Install the Alpha of OpenGD77 firmware for the (VERSION 1 - ONL). TYT MD-UV380 / Retevis RT-3S
HTML-код
- Опубликовано: 16 авг 2024
- IMPORTANT.
New radios do not use a genuine STM CPU, and the previously release firmware files will not work with this radio. However we have just found a solution to this problem and the updated firmware will be available soon
TYT / Retevis changed the CPU chip used in this radio, sometime at the end of 2022, which made it incompatible with the firmware. The new radios have an unmarked clone of the STM32F405VGT CPU, which is not compatible with the OS (FreeRTOS) which the firmware uses.
How to install OpenGD77 firmware onto the TYT MD-UV380 / Retevis RT-3S
See.
www.opengd77.c...
Note.
This is Alpha level firmware. Not all functionality from the GD-77 version is currently functional
Purchased a RT3S based upon the info in this video. Very pleased with how easy it was to upgrade the firmware.
This is really amazing.. I'll be watching the progress and will try it out. Thanks
Fine fine work Roger. I am now quite confident to make the change to the OpenGD77 firmware. Big decision at my age :) thanks
Cheers for this step-through - it helped tones! 🍻
Thanks Roger purchased tis to install the Opengd77
Excellent explanation. I installed it just now on my Retevis and it works fine. Does the FM frequency range open more to 200-300mHz in this alpha version?
Thanks for the good job.
The frequency range is the same as the GD-77, because the RF chip (AT-1846S) is the same as in the GD-77
RF PA and Rx amp stages are similar to the Baofeng RD-5R, but different from the GD-77.
Use on 220Mhz band for Tx creates very strong hamonics on 2 x the Tx frequency, but this is similar to the GD-77
If I were to purchase the MD-UV380 now would it have the cloned chip issue and not allow OpenGD77 to be installed? Thank you in advance.
Hi, I installed OpenGD77 on my MD-UV380 for 4-5 months, and I realized that, I haven’t save „test” file. Will my radio be useable, if I would like to return to orginal firmware?
Is the pinout for the programming cable different on the RT3S to the Baofeng DM1701? I made my own cable for the DM1701 but my pc says the RT3S is an unrecognised device, its not a driver issue, its the USB itself failing to find a device ID.
Thanks enormous for this!
Danke für das Video, ich habe es geschafft, Software läuft!!!🤪😁😁👍👍
Thanks for the guide - it works with my brand new UV390! de EI9LC
NECESITO CAMBIAR EL COLOR DE LA PANTALLA Y NO SE COMO HACERLO, ADEMAS QUIERO QUITAR ESAS FRECUENCIAS QUE SE VEN Y NO SE COMO HACERLO, ESO NO FUE EXPLICADO EN EL VIDEO
perfect tnx for all your work, hope it goes on, even on the lack with STM32 chips 73 Alex OE3JTB
Unfortuately. Now that TYT have replace the CPU chip with an unmarked Chinese clone of the genuine STM32F405VGT, it is going to be difficult to make the firmware work on the latest version of the MD-UV380 / RT3S
The problem appears to be that the clone is not compatible with FreeRTOS (OS) which the firmware uses 😞
Possibly one of the people who bought one of these new radios, may be able to debug why FreeRTOS crashes, but unless TYT or Retevis send me a free sample of this radio, I have no way to even start investigating the problem :-(
I notice a few links on the web instruction are now dead.

Thank you very much for your hard work! Will there be record option available like in the original firmware?
This firmware is not a modification of the official firmware, its a version of the OpenGD77 firmware, which is firmware written from scratch.
The OpenGD77 firmware does not have a record function, hence the OpenGD77 firmware when running on this radio does not have a record function
@@vk3kyy I'm not a native English speaker so maybe I asked this question wrong. I know about OpenGD77 and that it is alternative firmware not a modification. I'm just trying to ask if you plan to implement the record function just like you're implementing GPS function although it wasn't present in the original OpenGD77? Again kudos for your great work!
@@TTymek
There are no plans to add a record function to the OpenGD77 firmware.
The focus is to finish the port to this radio, as currently some features in the GD77 version do not work in this version.
It takes a very long time to get the firmware working on every new radio.
I bought this RT-3S in July 2022, and it has taken 2 years to get this far, mainly because Colin G4EML ported the firmware to the MD-9600 which has the same MCU as this radio.
So there are still many months of work before the port to this radio is even finished.
@@vk3kyy thanks for the answer and good luck!
Thank you for video and explanations.
Question: Is the Hotspot function working in this firmware?
It will be a great functionality, to use this HT in Hotspot mode, like in others radios like GD77 or DM1801.
73!
Hotspot function is working.
Note. The USB connection on this radio is not as reliable as the GD77 even for codeplug data transfers etc, so will probably require more RFI screening than the GD77, otherwise the hotspot will disconnect
73 thank you very much.
Hi, whats the overall benifit of using this firmware? Does it allow more contacts to download and overcome the 120,000 limit.
Is it now possible to install on newer version of md-380? Maybe I should buy md-uv390? I cant find any seller that provides info about md (what year it is and what version).
Thanks!
This looks really interesting, I can buy a TYT MD-380/RT-3S in the UK quite easily, I was trying to get a GD77 but I haven't found one for sale new or used. Is there any downside going for one of these over the GD77?
RF hardware is not as good as the GD77.
Battery life is not as long, as the radio takes more current.
But it's currently impossible to buy a GD77, probably because of the global chip shortages, as the CPU in the GD77 is basically unobtainable at the moment.
@@vk3kyy Many thanks for your reply, I will keep looking for a used GD77 on eBay etc. I may just grab a RT3S as well to play around with.
The firmware link downloads/DMUV380/Firmware/Latest doesn't show the .bin files as at 12/12/23.
firmware files have been packaged as .zip for several months because the firmware is now separated into firmware executable and language pack, as file size of both the firmware executable and all the merged languages was larger than the total ROM of the MCU in the radio
You need to use an up to date version of the OpenGD77 CPS which supports the .zip packaged files
@@vk3kyy I unzipped the file and installed the Boot. Installed CPS but it wants a Serial Port. I have the USB device in DFU mode. How do I get that to work?
@@VK2AHB
As I said in my previous post.
You need to use a version of the OpenGD77CPS which supports handling ZIP FILES.
You CAN NOT unzip the file and use the contents
Also. The firmware update is not via COM port on any supported radio.
The UV380/DM1701 use the STM32F4 series MCU's and use STM's Device Firmware Update system including the STM DFU device driver.
Search RUclips you'll find loads of example of people showing you how do update the firmware.
@@vk3kyy Hi Roger, I found the right zip file and it loaded. THanks.
Can be applied this update to the only UHF band walky's RT3
Thanks for your reply
No.
The RF and DMR hardware inside the RT-3 is completely different to the RT-3S.
@@vk3kyy Many Thanks for your reply
Is your firmware compitable with TYT MD-UV390 non-gps model?
Yes.
Will this firmware can scan two TimeSlots at once like an Anytone?
@@GSampiyonable I don't entirely understand your question.
If you are saying, can you set the firmware to listen to signals regardless of whether they are on TS1 or TS2, then Yes, and this is done by turning the TimeSlot filter off, in the QuickMenu
It also by default will receive any TG, including PC, unless you enable TG filtering
It can't however receive on all CC, it has to scan for the active CC and lock onto that, as the hardware is not capable of ignoring the CC
See the OpenGD77 User Guide
@@vk3kyy Yes, that's exactly what I'm trying to ask. You understood exactly what I was asking. Sorry for making it a little confusing. Compared to factory firmware, this is a huge leap forward. I will try asap. I'm looking forward to the Beta phase. Thank you for your hard work. :))) 73
What is the overall functional improvement? What are the sat keps used for in this radio? Very nice changes and I will be doing the change if for nothing more than a better uncluttered screen I can put into inverse mode. I don't see at all in one eye and the others not far behind.

How can one access the ID database in the radio? I wrote around a hundred but when I listen to DMR repeaters no contact info is shown.
Did you write contacts or ID's . It seems unlikely that your wrote 100 ID's as each country has thousands of IDs which the CPS downloads from www.radioid.net on the DMR ID's screen
@@vk3kyy I wrote the dmr id database, the one thats automatically uploaded to the radio
I put the open GD77 on my Baofeng RD-5R works great and I love it. Can I put this on a new Retevis rt3s without having to put original software or updating firmware? Do you know how many contacts can be put in Retevis rt3s with open GD77?
You have to follow the steps listed in link, in the description to install the firmware.
The firmware uses the GD77 codeplug format, which AFIK has the same number of "Contacts" as the official firmware.
However, I doubt you mean Digital or FM Contacts, because no one needs over a thousand of each type of contact in their radio.
I suspect you mean DMR ID's for callsign and name lookup. In which case the maximum number is just over 2 million.
@@vk3kyy thanks for your help
Hi Roger to download the whole world what number do you use .Thanks
Its a filter.
Enter nothing
The process is the same for the new tyt md-uv390 versions? Just have to use the new beta from the forum?
Yes. MD-uv390 is the same as md-uv380 except is waterproof. Firmware and installation is the same
@@vk3kyy Thank you very much !!!
Can OpenGD77 receive two frequencies at once? I didn't find how to do it.
No. The radio only had on RF chip. It can only receive 1 frequency at a time.
You can scan multiple channels, but this is not receiving 2 frequencies at once
@@vk3kyy I meant it. Follow the two frequencies, and take the one that has a signal. As in the original firmware.
How to turn on scan mode?
See the OpenGD77 User Guide.

Ok but on RT3S this buttons run squelch but not scan.
Ok I didn't understudy that it need to be hold ;) my fault thanks ;) by the way you done grat job many thanks for that
But I found that it doesn't work on VFO mode only squelch is going down when hold UP arrow.
I even loaded firmware once again and it is the same problem, scan works only in memory mode. What am I doing wrong ?
this video is a lie, my dm1701 dont turn on more after this video
