Here's how to firmware update on your FrSky receiver, like the FrSky R9, without ever removing it from your quad. The secret is a feature called Betaflight serial passthrough. I'll show you all the steps for how to update the firmware on a Frsky receiver using Betaflight serial passthrough.

Glad to see you talking about the R9, wish you would do a video on Crossfire vs the R9M, best wishes, also, do you know when Liftoff will get the new map?
LuGus will make the announcement. It's still a few weeks out.
Joshua Bardwell Still waiting...... 😉
Just bought a wing and can’t wait to see this 😁
P.S. please can you include details for us Euro’s? Many thanks
this works on all receivers not just R9
Thanks JB for another great video! Does this work for the Flex firmware as well?
I don't see why not.
My R9 MM won't bind. So I like to upgrade the firmware with this method. I added a switch in the 5V line of the receiver. I have exactly the same configuration in the Ports screen as shown in this video. But if I enter 'serialpasthrough 2 57600' I get the message 'Port 2 already open, setting baud = 57600' and the frsky update tool is not able to find the receiver. Any tip? I use the JBardwell F4 AIO board. Why is the port already opened?
What are you wearing for pants?.... it looks obscenely comfortable. lol Love ya Bardwell!
it's called saroong (in malayan language). it's a south east asian clothing...
You can also use serial pass through on the Matek VIDEO TRANSMITTER 5.8G VTX-HV to update the firmware by connecting up rx and tx ,but I don't know if you can do this while video and audio are also connected and it's installed in your quad? www.mateksys.com/?portfolio=vtx-hv#tab-id-6 ,I will have to try it.
Unfortunately I don't have a windows computer... I might have to try installing windows through bootcamp
I remember back from the first generation of cellphones, respective MP3-players: When flashing firmware I don't move at all, like "hold your position until it's finished... ,D"
I always hold my breath doing things like this lol
By the way: You can also flash the R9M Module during this method. For example you have a nirvana and cant flash the module during the radio. Connect the sport, plus and minus of the r9M module to your fc and choose the right file for it. Works great!! I hope i could help.
Greez from Germany. :)
posrproductions - thank you my dude. I have this boi integrated into my flysky is6, and therefore, cannot update it like you would with a taranis... I thought this was possible, but I had to check the comments, lol, thx.
hi mate what FW you are using and did you power the r9m module via fc? thanks stay safe out there .
Help please - I bought this quad from a guy who said FPORT is already setup, not being able to bind to my Taranis Q X7, looking to the update the Frsky R-XSR ultra mini via this method, but it is not able to find the device using the Frsky utility, have a JB F4 AIO and on BF Serial Rx is on UART3, I can see that the s-port yellow wire is connected to 'Tele' on FC - should i use 0 or 2 in serial passthrough command ?
Trying to do this with MacOS.......any problems known doing this?...before I screw it up :)
Nice tutorial...two questions: 1) will it work rousing fport? 2) once you finish the procedure, do we need to type something in the cli to restore the initial configuration?
Yes it will work using fport. To restore original configuration just power cycle the FC.
Solder bridge on the back?!?
That’s one fewer beer I’m going to buy you, one of these days.
I'm trying to put legacy firmware on a r-xsr on a speedybee f7 aio for use with jumper t lite. I've tried so many different things I've lost track. No matter what I do, the update tool doesn't see the receiver. I'm lost. Anyone ever do passthrough on a speedybee? Am I missing something in wiring, uarts, commands?
2:15 made me nearly spill my coffee when jb said that
Have had no luck with GEPRC phantom and XM+ receiver, tried multiple ways, also had problems with a baby ape before and had to de-solder and do manually.
Let's not forget this is still extremely useful to pilots with Devo radios or other radios compatible I don't know of. Thanks so much!
How do you wire rx mini to FC please
I was thinking... Can i use this methot to flash the r9m transmitter module.. I hope if i just connect the transmitter sport pin instead of the receiver and select the firmware for the r9m there isn't going to have any problems... Because i use it with a radio that doesn't have a sd card......
hi mate have you found any solution by yours thanks stay safe.
Hi. I have an hobbywing xrotor f4 g2. It doesn't have an s port. Can you please tell me how to set it up.
You can update the R9M module using this technique to. Use the S.port on the under side (bottom hole, and ground is second bottom hole.), then plug in TX30 2s. I have a Nirvana...
THAN YOU!
could you elaborate the process a bit? do I use the s.port and ground wire from my receiver and desolder it for the process?`soI need to solder my r9m to my fc's receiver cables?
@@XJ1345 hi mate did you find the solution of this thanks.
@@FPVrare I ended up buying the Frsky STK tool to make updates. If I remeber correctly I couldn't get it to work this way.
Thanks mate I'm planning to do so also.
Hope this works as my betafpv lite2 $40 doesn't have plugs
Hi With which program can I upload the update files to the R9 STAB rx? Thanks Gianni
great stuff mate
Hi hope you make a video flashing expresslrs to r9 thanks!
I bought crux3 with rxsr soldered in. Will this work for me?
Yes i'm out there :D
Never used a Crossfire.. Happy with my R9M, R9 and R9 Mini's.
hiya josh, great vid
Q: what uart would you use to update the receiver if smartport is on softserial?
or would it be easier if i put it on eg tx3
Ummm I know the softserial ports have a number that you can redirect but I don't remember what it is, or where i saw that.
Maybe just easier to put it on uart 5 then.
Thanks v much 👍
If they implemented OTA programming like crossfire then it’s a nonissue.
+1 for Crossfire OTA updates
How much is the difference between EU - LBT compared to US NonLBT?
STephanM
I think the only difference is the MHz 900 for USA and 868 for EU... I think.
900 MHz is the same as the GSM network in the uk so it’s a no no
I have a jumper t8sg transmitter so theres nowhere to plug the rx into the tx
Will the pass thru work for r-xsr same way?
will this work to flash an xm+ reciever?
DOT WORK if use softserial
I cry(((((
i moved to the us just for fcc. no honestly..
Is there no way to put the R9MM into bootloader mode from CLI? Would make this even easier. Have my R9M and R9MM coming in a few days. Looks like a PITA to flash the thing, with it not having a plug like the RXSR
Or perhaps a CLI command to make the RX power cycle even?
Could I do same thing to flash the module firmware by the sport pin on backside. I'm using a jumper t8sg v2 plus radio running under deviation TX and the pxx protocol don't work on my r9m 2019 cause of acces firmware I think
Yes. The FC doesn't care what it is flashing.
@@JoshuaBardwell you make my day 😊. Thanks for quick answer
@@JoshuaBardwell if my s.port is softserial1 does I have to enter cli command serial pass-through 10 57600?
I am trying to update the firmware of an r-xsr with the Betafligth and when I start the FrskyUpdate the screen only shows the comm 11 and also not available. I can not change to 3.
I've tried running it as an administrator and putting comm 1 to 57.600, but nothing.
As I have the open drone I have disconnected the whole receiver to prevent it from being powered, with the idea of connecting it when the updater needs it. It's okay ?
In the port configuration the UART3 is at 19200 and Smartpor is selected in automatic and Rxserie off.
The Rxserie is only activated in the Uart6, which nevertheless has the MSP disabled.
You can help me?
The actual COM port number depends on your computer. It will vary. If COM11 appears when you plug in the FC, that is the one to use.
@@JoshuaBardwell In Betafligth I connect with Comm11 but the problem is with the Frsky update, in its screen do no shows any comm port avalaible. It shows Comm 11 but shows a message that it is not avalaible. In your video in the 10:54 minute you can choose the comm,
I can not.
Maybe it's a PC problem, but I've updated the Com and Lpt ports from the file manager and still Frsky updater does not find open ports.
I HAVE WINDOWS 10. Can be a compatibility problem?
Would it be possible to update R9M modul with Serial Passthrough?
The module? I don't think so. It just plugs in via USB.
Just a note for those who have FCs that power up the RX [ R9 SLIM in my case ]:
Disconnect the R9 SLIM cable > connect FC > Do exactly what JB does until he plugs the battery. At that moment you don't need to plug the battery, only the cable into the R9 SLIM RX. This will do the same effect, it will solve any issues of FRSKY update tool not detecting your RX.
kind of unrelated but JB i cant get telemetry to work on my dys F4 mini with my R9 mini reciever, ive tried everything sport, seaching for rssi sensors through my transmitter but it isnt working what should i try now? oh and i cant seem to update the receiver for whatever reason.
SD card reader in my qx7 is broken so this was only option to switch to EU firmware on my new R-XSR and man... without your help I would never get it to work so many thanks....
Edit - works on DALRC F722 dual and r-xsr (in case someone needed to know)
any chance of flashing xm+ via betaflight?
Have you try? I'm curious about it
Hi Joshua,
great video!
I'm trying to update my RXSR-FC (Omnibus F4 V6) using this way, but no of the UARTs in the list in Betaflight Configurator has Smartport enabled in default config. Also the manual says: Resources for Smartport are "Software serial", while the other functions have some UART assigned (e. g. SBUS is UART1). Do you now how I can update the receiver?
looks like this is the Video for me... i bought an R9MM receiver and was surprised there werent any cables coming with it.. but maybe i just create some extra cable stuff to plug it into my xlite pro since nothing is soldered atm.. :D
Hi Joshua! Love your vids. I learn something every day ;-) But what I cannot find anywhere is what EXACTLY the differences between the 'normal' firmware and the FLEX firmware are. Unfortunately the Chinese are not very good in explaining the stuff they sell. Could you shed some light in the dark here for me, plz? And... Does changing the firmware from EU-LBT to FCC actually change the frequency from 868Mhz to 900Mhz? Thanks! Keep up the good work. Cheers!
Hi, great video but i'm adding smtg for F7 guys that are tilting with it. WIth F7 controller, the easiest way is to activate Fport with josua's video and after follow this video but instead of selecting smartport on telemetry, just activate Serial RX of the uart needed. That's the correct way to do it with Fport :) i found it after 2 hours of research so... i'm so happy
Your video are awesome josh keep going
another popular youtube made a video saying micro motors ate burning up on the new betaflight 3.4 and up.. and oddly enough I've noticed motors getting wayyy hotter on my babyhawk r. any thoughts?
Try BF 3.5 :-)
Joshua Bardwell configurator 10 3.1 firmware 3.5.0... just did a test flight and super hot motors after about 2 minutes
May you do a "How to use 16 channels on R9M (EU)" ????
A lot of EU-Users would appreciate it.
Thank you! Your video saved me the time waiting for the frsky tool. I own the nirvana and as awesome it is, it can't upgrade modules and receivers. I got myself into r9 and of course it wouldn't work without the upgrades. I took an old crazybee f3 aio fc put the r9mm on it, set up serialpassthrough as you showed it and it worked! Then I cooked up a connector for the module (you don't wanna know) and upgraded it too successfully. Now everything works! God, I love this hobby!
I have a huge request to you. I also have nirvana, myself with this software uploading for a few days and I lack strength. Previously I tried on Matek F4, now I came with a mini F3 controller and did not. Can you help me find the reason why I can't upload the software? I come from Poland, my mail is gkochab@gmail.com
hi mate you can even do on the r9m module? where did u connect the s.port thanks.
@@FPVrare bottom pin is the signal, the one above it is ground, the one above it is the voltage. I cut a paperclip in 3, soldered the wires to them, plugged in these holes in this order and prayed so it doesn't come apart anywhere during the update. That's it. Since then I learned there is a smart port in the front too. That might be easier.
@@athefpv4670 wow thank you mate im gonna try this thanks for helping does the upper pin still the PPM input? for r9m if your familiar.
@@FPVrare it should be. The module supports ppm so it must be it
It will not brick it to lose power during flash. It will brick the firmware, but the bootloader will still be intact to reflash the firmware.
Still don't lose power during flashing that's a bad idea!
You know the TBS guys please tell me they didn't just try to squeeze frsky team Black Sheep spent so much money on their image.
TBS would have to know that this would get out all I can tell myself over and over again was what were they thinking what were they thinking and all I can come up with is it's a big lie because this would destroy their image in fpv community
Why not just have an over the air update? ;)
Indeed...
Because it would cost more and then people would again be looking for a cheaper option.
Awesome, JB!
BTW, I'm thinking about making a adapter cable to flash the firmware of XM+ receivers, but I don't know how yet. Something I could use without soldering any pins. I'm going to do the same with R-XSR receivers, but as it already have a connector it's much easier.
Use female to female servo connector, don't forget to rearrange the pins in the connector on the radio side if you're using X9D because the GND VCC data pins aren't aligned correctly which will be resulting in smoke! Also, make sure the battery in your X9D isn't over 10V because the VCC is a direct battery voltage.
Frsky tool didn`t find COM port which I was using for betaflight (COM3). I workaround it by that I start FrskyTool and it found some other COM1 port, then I remap COM ports in windows device manager, at first other device remap to COM2, and then betaflight (holybro) COM3 I remaped to COM1. After this, I start with flashing procedure, do passthrough in bf, close bf and then connect battery to quad, after it FrskyTool (which was running from beginning) found my receiver firmware version... so I was able to flash new one.
Hope it can help to someone else with same problem with frusb-3-fuc-3 (frsky_update_sport_rev14.zip) tool COM port problem.
Wow that is a lot of manipulation, isn't easier just to desolder 4wires?
I have the same problem, frsky tool is not recognising the com port which I connect fc to. Which driver do you use ?
@@Simofly I installed driver from frsky wesite: www.frsky-rc.com/frusb-3-fuc-3/ and also I tried USB driver Zadig zadig.akeo.ie.
But trick is to run Frsky Tool(do not turn it off!), and if this tool see any COM port, then just remap ports in windows device manager, so your FC will be using port which frsky tool seen before :)
Hey JB, what if my smartport/telemetry is solderd to UART3, but it is working via SoftSerial1?
I think you must use the softserial interface number, not the UART3 number. This number exists but I don't know what it is. I've seen it before... I'm pretty sure you can do passthrough on softserial. But I don't know the CLI command.
@@JoshuaBardwell its softserial11. So i need to use 10 or 11 when i type the command?
Damn it no smartport.. I wanted to do this.. i have cinepro 4k..
R-xsr won't bind to internal accst d16.. only xjt lite module..
Trying everything to fix it
Definitely need to update the firmware either on your internal module or your RXSR. If you can't update the RXSR then update the module.
@@JoshuaBardwell updated internal module even though it already had the latest. . Updated radio. OpenTX. R-xsr only thing left but drone has to be taken apart. And I think capacitor unsoldered or power cable (cinepro 4k) im a novice still learning. Just frustrated. I'd pay u to do it if u lived near by.
Module on the latest firmware but what if the RXSR has old firmware. You may need to roll back the module to pre-2.x firmware.
@@JoshuaBardwell none offered on X9 Lite S page. Can I use X9 Lite? (none S)
@@JoshuaBardwell omg yes other lite radio firmware worked.. it worked.. works now thank you so much..
Hey Joshua, say you want more range and happen to have a 2w 2.4ghz booster, and a taranis x9d se. Is it possible to remove the stock antenna, and place the 2.4ghz booster inline, to say a higher th I antenna?
What is the BOD rate? Is this related/established by your FC or receiver?
If you've got a power-over-usb FC (JBF4, CLR F4S, and Kakute F7 are some that I have used and confirmed the following for) and an Rx that uses a plug-in style wire harness that is connected to the power-over-usb 5v pad, then simply leave the Rx unplugged from the harness while you set up pass-through and start the FrSky STK, then plug it in once you are ready to write to the Rx. Works perfectly for me without having to change my wiring away from the power-over-usb 5v pads. Unfortunately for R9 Mini quads (including my own) being a direct solder Rx this trick doesn't apply. Just updated my R9 Slim+ this way and will be doing this for all of my R-XSR quads as well. Thanks Josh, informative content as always. Hope this tip helps someone out there.
thanks again you legend!!!!!!
keep up the good work.
stay as safe as poss. but keep bringing on the vids.
nice - but is annoying (receiver power up only with battery) when you want to use your kwad as connector for playing simulators, which is possible in the latest Betaflight releases.
Tested it yesterday to update one of my r-xsr receivers to Fport, like you mentioned 'as long the receiver is not powered from the same rail as the 5v USB it works flawlesly. Well ok it'll take some time, but much better than unsolder your receiver.
Is that a skirt?
FYI you can just right click, go to 7zip command, and click extract here. It extracts the files to a new folder with the same exact name as the zipped folder.
Good, I thought that Windows had to be smarter. Thanks VP, any chance of flying in the Kremlin?
I have to say it.... cause I know there are others that won't. Watching this video was super informative. But as much as I really wanted to purchase Frsky's long range system I will not now. This updating thing has gotten out of hand on more then just this system. But I think this is totally ridiculous. Why can't it not come ready to fly updated and all. I use a Mac and along with everything you did there will be even more hoops to jump through or odd steps to this lengthy process. I love you but no thanks FrSky!!
blabla
Just desoldered last night to upgrade my R9 mini. Thanks for saving me time next time I have to update my R9 mini and slim+!
I heard something about frsky is going to make a new firmware for the EU r9m. Do you know something about it? Seems like it's not doing full power from what I read.
Make sure to have the RX off while setting up serialpassthrough, I found that otherwise I'd get "Could not get device version".
how you wire it ?
Is this possible to do using F.Port?
Good job 👍
ok maybe i shoul watch till the end until ask questions :) deleted my previos comment. i think i need to desolder anyway but: can i check firmware version of the receiver without the update tool?
No way I know of to do that.
Have anyone ever figured out an solution on how to revive a bricked receiver because sadly i have about 3 lying around at home :|
Apparently the bootloader should still be intact - so it should still flash. But yes I have inop. rxs that will not flash. I'm gonna try using a USB FDTI adaptor next I think.
Hey brother! I know questions in the comments are super long and inefficient... I have the XM+, your JB FC, and the XJT module :( And no friends who fly FrSky :( . Is it "Serial passthrough 0 57600" since the sbus is going into UART 1 as I understand it? Or am I misunderstanding things completely?
Yes that sounds correct.
Interesting... I’ll keep fiddling with it then thanks. Thought I followed all the steps but I’m obviously missing something. So badly want RSSI on channel 8/16 (hence me attempting to update). Thanks friend!
SUCCESS!! THANK YOU! I was not clear on terms & meanings... Temporarily moved the receiver SBUS wire from the SBUS pad to the SmartPort Telemetry pad and it recognized & updated (still a little foggy on terms and differences; serial port vs. UART, SmartPort, SBUS, why serialpassthrough only forwards to a smartport and not an SBUS, etc :) THANK YOU! Now I have OSD RSSI. Silly XJT module... Just love my old JR radio.
Joshua what if sport is on a softserial port?
I think it can still work but I don't know the port number to use in the serialpassthrough command.
For SoftSerial1 use 30 and for SoftSerial2 use 31. Still, I couldn't get the FrSky tool to properly connect to the receiver. Let me know if you managed to flash over softserial.
I will try to updade de xm+ on my mobula 7 using this method, i need to unplug the power wire and conected later.
May be this solves the binding problem between the x9lite-s lbt and the xm+
did you manage to configure the R9 receiver and transmitter according to the instructions? Could you help me?
@@MusicOnlythebest i have already binding it and there is ok at the moment. I have to use a script on cli, because the light dont change color. I dont need to update the xm and at this moment i have bindid the m7 and tinyhawk.
Hey Josh, I have the Matek F405-CTR and my Smartport wire is soldered to the TX2 pad but I had to assign it to softserial. What should I type into the CLI to enable pass through?
I think it can be done but I don't know the port number. I asked the Betaflight FB support group here, so click through and when they post the answer you'll have it too: facebook.com/groups/betaflightgroup/permalink/299599867402563/
i have updated my XM+ while its connected to the FC. i just tinned the tips and connected it to the controller.
I updated the wiki with this info, and linked to your vid. There were some pieces missing in the wiki. Thanks.
So to use serial pass through you have to be using F.port right? Wont work with sbus right?
No, not at all. Serialpassthrough doesn't care what protocol you're using.
This method would also work for upgrading the R9 (the big receiver) and the R9m transmitter module? Thank you!
Yes I believe so.
Josh we really need to look how you unzip files and copy them ? Thanks to show us how to unzip, almost learned new thing
Hi, Jan. The software I use is 7zip
www.7-zip.org/
Here's my problem... I use a Jumper transmitter so I can't do it through that and all I have to use would be soft serial. Is it possible to do this through the soft serial as done through a uart?
I don't see why not as long as the baud rate is supported.
Ok so I successfully flashed the xm plus this morning. I have kakutef4v2 and it has smart port on Hart one. So I moved the subs wire to smart on the fc and the flashed worked.
Hi Kemonric, please can you explain it little more what you mean with "So i moved subs wire to smart on the fc?"
I have also kakute f4v2, smartport on uart 1 (so serialpasstrough 0) but frsky update tool won`t find my COM PORT which betaflight was using.
@10:08 - What if you are using softserial? What command do I use in the cli?
I think it can be done but I don't know the serial port number for softserial. You should ask over on the betaflight support group and see if a dev knows the answer.
would something bad happend to the FC if i flashed the receiver with the s.port on the taranis while it still is conected to the FC? cause i did it :/ i have used servo pins to get it mounted solid. (just like one the magnum f4 stack) so it was very easy to just add the flashing cable to the top of the pins. i left 1mm poking out of the receiver so i can use a servo plug to flash it. but i noticed the s.port cable from the taranis powered up the fc also :/
If you are going to flash via S.Port yes I do agree you need to disconnect it from the FC.
I already did it. Hehe. The fc made some extra beeps and it drained the taranis battery super fast but it seemed to work.
I dont think its possible to write via the tx pad to the FC.
I've used passthrough before with your FC and had no issues.
Hey JB, thanks for this. Have a couple quads that I have been putting off updating the rx's because of course theyre buried in there all soldered up. This is a big motivator.
Can I ask what the 4 different colored icons are on your task bar that look like periodic table atomic symbols?
Adobe Creative Suite.
Hi! Thank you for tutorial. When I launch this fw updater tool - there is no option to select com port at all, just empty field. Have you faced with it?
If you’re on Windows then you need the STM micro electronics driver. 👍🏻
Would a single pin wire plug or small barrel connector on positive lead to receiver more simply allow the update period more accessible?
To me it seems like my way is better but yours would work.
My curtains have the same pattern as your dress
Hi there Mr Bardwell,
greetings from Hungary (a small country in EU).
Just one question: does the whole procedure apply for updating the TX module as well? (or alternativelly could it work?) [I own a 9XR-Pro with an updated OpenTX]
Cheers, keep up the good work!! :)
The TX module is updated by putting the firmware on the SD card in the Firmwares folder. Then on the radio, long-press Menu. Press Page to get to the SD Card screen. Navigate to the Firmwares folder. Highlight the .frk file in question and long-press Enter, then select "Flash External Module".
(Or "Flash Internal Module" if you are updating the radio's internal module. External module is for the JR bay.)
this is going to be soo useful. I'm also running an r9-mini.
Wait, is this a process we can use to find what firmware is on the RXs we have? Or is there a way to find what version is on the receiver?
Yes, it shows the current version in the app when you connect.
Nice Video! I'm not having trouble updating r9, but connecting to MW OSD, I've got some crappy old backup backup backup Quad, which has the Flycolor Raptor 390 stack which has MW OSD R1.5, you're supposed to be able to connect using serialpassthrough, but in the MW Osd GUI it gets stuck reading or doesn't start to read at all, so I can't configure it, do you have any tips?
Make sure baud rate is set correctly. Power the MWOSD at the right moment to catch the bootloader window. This is the hardest part. If you use an FTDI adapter it has the ability to reboot the device to trigger the bootloader window. But that doesn't work over passthrough.
Joshua Bardwell Thanks for the response, I don't want to flash it though, I want to connect it, I'm sorry if that was confusing.
Ha! Joshua whats up with the ImmersionRC - TrampHV its been out of stock everywhere for over a month?
No idea. All I know is everybody is waiting for shipment from IRC.
Joshua Bardwell ok 👌 thanks
What if it says port 2 already open? Just sits on finding device. x4rsb on the jbf4.
I got it to work. Next to smartport where it says auto I changed to 57600 and it worked
I'm not sure I know exactly where you've gone wrong but if you follow the steps in the video exactly, it should work.
@@JoshuaBardwell I finally got it to work. In the ports tab next to smartport where it says "auto" I changed that to the 57600 and it worked.
@@JoshuaBardwell I am however still getting repeated messages from radio "telemetry lost" "telemetry recovered" over and over.. Any ideas on that? It even said "sensor lost" once tonight..
@@JoshuaBardwell ahhh I just found this information.. This is my issue.
"It is possible to receive spurious "telemetry lost" and "telemetry recovered" messages when the transmitter and receiver are less than a meter apart.
This is not a malfunction and will stop when the 2 devices are physically separated."
so what if i hv a qx7 i do have a receiver that i can just unplug and do the old way BUTTTTT i updated my QX7 now it wont see the pins on the bottom to update my brand new r_xsr just get errors that it cant see the pins on the qx7 display :(
StaticMotion I have a similar problem. Do you get bottom pin error ? Or does the flash just not happen ?
chris colburn both can’t flash or see pins it happen after I flashed my qx7 so idk maybe I’ll just get the frisky flash gizmo
StaticMotion I got the gizmo coming today in the mail because I got a r-xsr that my x9d+ jacked up and I can’t get it going. Hoping the USB port flasher will work.
