I bricked my x99 mobo trying to unlock the bios... Bought a ch341a programmer and followed this video, now my mobo works fine again!
Thank you very much!
Thanks for the support 🙂.
if everyone know how to explain like you no one will get lost ever. thanks a lot .
That's clearly best guide for me. My Hp 7200 MT workstation's bios had corrupted. I tried many ways to fix it, but failed. Finally, without desoldering, i followed your guide and made all steps. Your guide brought it back to life:) I appreciated. Thank you so much.
This video is going to help a lot of people, thank you for making it!
It saved my x79 motherboard from trash bin. Really helpful video.
i guess Im asking randomly but does any of you know of a method to log back into an instagram account..?
I was stupid lost the password. I appreciate any tips you can offer me
Clear and concise instructions. Really easy to understand. Made flashing my ROM easy. Thank you so much.
Phil's computer lab mentioned you today! Hell yes, your channel deserves so many more followers. Such great content.
Thank you for the support!
Thanks for your work. It’s easy to see the love that you have for technology, and for sharing it. You are helping a lot of people ^^ I hope it returns double as you give. Have a nice weekend :) and keep doing that you love, you are doing great 🙌✨😁
Thank you Ricardo!
Complete and clear video with all the information needed and no other crap. Thank you very much
Awesome. Have this programmer on order. Need to flash a bricked laptop and hopefully bring back to life. Nice work as usual , thanks for the info
Absolutely amazing instructions and work you do for us! Thank you my friend! A life saver you are.
I found a non working s400ca Asus Zenbook. that wil live another day thanks to this guide. Thank you very much!
Your channel deserves more subscriptions. Hope you will make many useful videos about computer engineering!
Wow. This is an incredible resource. I cannot put into words how thankful I am! :)
Been waiting for this, thank u!
Glad to have made it here. This is the advanced internet user type video ☻
thank you very much, I admire your work you know a lot about computers, I was able to recover the bios of my motherboard thanks to you!
Another satisfied customer. With this vid and others, I was able to un-brick an asrock a320m mother board that I was trying to update normally for a ryzen 5700g.
I am glad to help. 🙂
i been searching for this video good job man
This item is helping me with badly modified bios.
I tried to change the logo of Asrock G41M-VS3. Didn't boot afterwards but I flashed it using file from official asrock site. It worked again.
Thank You for the awesome tutorial! 👍🏼👍🏼👍🏼
this is gonna be really handy with secure boot bricking everyone's gigabyte motherboards when they're trying to install windows 11
This has just happened to me
@@ULTRAJSKand to me 😂
@@CisumAPRAT What happened??
@@MrMalam1234bricked the bios on my gigabyte b450m ds3h while trying to enable secure boot for win 11, because i kept going fast in the bios menu 😂, but i reflashed the bios with the ch341a and everything is perfect 👌
This channel is a gem!
Thanks!
Excellently presented video for peeps like me who need to be talked through each phase to complete the job. I will add to this comment when my USB Flash Programmer arrives. Once again thanks for a complete tutorial for this process.
Did it arrive?
Yes it did and it enabled me to restore the chip that I have.
How do you know what series of chip you have? Since 2300 and 2400 go on different sides of the programmer. Did this work for you?
By searching for the instructions for my programmer
These instructions are perfect. Thank you so much.
Managed to save my board ,thanks.
Thanks man!!!!! Im only here to watch how to program but also great video! Too useful for those that bricked his bios (srry for my English)
Thank you for this video I managed to save my Z170 pro gaming mother board with this device and tutorial
Thank for your explanation!!! It's so helpful
Thank you man, your videos are really helpful
Ima download it thanks for sharing!!
I am going to try flash my z170 pro gaming bios chip tomorrow. Using your tutorial hope the programmer i get is not faulty.
Good luck with the project!
Thank you! Very well made!
Thank you realy needed this video
This guide saved my B450i Strix, only thing I did differently was that I used Neoprogrammer.
Hey man! I've brick my b450i strix can you help me bringing back to life by telling me everything you did ? Thanks in advance
Thanks to your video howto guide! I was able to flash my old x58ud3r mobo. Unfortunately, it did not fixed the constant reboot issue.
Muchas gracias por tan valioso material, sos un capo!!
Golden channel--- nice content-- subbed immediately 💯
Thanks - managed to restore a functional BIOS to an otherwise bricked motherboard because of this video. FYI the ASprogrammer software had some pretty serious graphics distortions on my display, but functionally it worked perfectly even so- might be reassuring for others to know. Thanks again
Hi there , it was one of your best tutorial video . it was awesome and perfect and informative tutorial video . keep it up . thnx
A very useful video... Thanks alot
Thx for the PSU trick helped me a lot
As always, everything is super. Waiting for new cheats from your side
thank you! great video
thanks so much for this video. Helped me to update bios after black screen after undervolting on Gigabyte g5 kc. I did not believe it, until i saw first message on screen. But I had interesting problem, that it could not connect with usb3, but it worked with usb 2 connector ...
Your USB 3.0 port might be implemented through an external controller which does not provide enough power. Good job reviving your motherboard!
very nice this gives me little confident
I have a question, what would happen if you per exemple leave fans, cpu, rams on your motherboard while doing it?
These extra components may drain some extra current from the programmer and it may fail to detect or properly read/write the BIOS chip.
Love you bro it was very much usefull
Good tutorial
However, to clear CMOS you just use the jumper as indicated on the motherboard OR you remove the battery but not BOTH.
The program FLASHROM can be used from the command line, it does use CH341A as an option
Good luck
many thanks for the great video helped me thank you very much
Great video thanks
You skipped one step, before starting to work with AsProgrammer, need to install CH341A drivers on PC, where u configuring new bios.
Thanks for your vid, very helpful!
True, I spent hours looking only to discover Windows update can download driver (under advanced options)
Thanks alot!
Esperemos que este video me funcione mas adelante saludos bro ;)
Thank you very much brother
Hi there , it was great thankyou
Heads-up for those wanting to flash a bricked old X58 motherboard (Gigabyte X58A UDR3 Rev 2.0 here), I had no luck using AsProgrammer1.4.1, but was able to successfully flash my BIOS chip using CH14AProgrammer ver. 1.1.1.3.2.
Thanks for sharing the info.
@@Miyconst No problem. Ironically this was an Aliexpress refurbished board that the seller explicitly stated on the listing "Updated to the latest BIOS for maximum CPU compatibility"... didn't POST or put out any signal at all, tried absolutely everything you could think of... eventually I decided I may as well get a BIOS Flash Programmer tool as a last resort (return period had already passed before I tested the board as it looked very clean and like new) as I suspected the seller did not actually update the BIOS which would prevent my Xeon X5675 from being recognised... and what do you know... as soon as I flashed the BIOS the system worked perfectly haha... I think the lesson to be learnt is do not trust Aliexpress sellers to always be honest.
This is a great tutorial that explained things well enough that my monkey brain could follow it. Thanks!
Thanks a lot ❤️
What a nice video
Most new chinese motherboard come with Winbond 25Q128JVSQ. What program do you use to flash it, because even CH341A 1.40 does not have that bios model listed.
As far as I know it's compatible with the Winbond W25Q128BV, at least I always select this option from the pop up window and it works.
Gracias, muy buen video pude arreglar mi rx580, sludos
Found this tool on my nightstand not knowing wtf it was. :D
Thanks!
Great video, thanks.I hope i never need to use this info
❤️❤️❤️
Good morning sir I have one question for you , I have CH341a and I have clip SPI 8 and now I have clip SPI 16 so how to use with this programmer?
Hi there, what is the difference between 24x and 25x on CH341A programmer? thnx
Thank you for the video first of all. Since I see likes to post, I'll go ahead and ask: I'm using a NeoProgrammer v2.2.0.10 but so far when I want to open the repaired BIOS Image that someone has done for me, that has access to LBE++ BIOS Extractor (dealing with an HP BIOS here), I get the error message File not open, press ok to ignore & risk data corruption or abort to kill the program. Any ideas why that happens? What going wrong?
When I press ok, the cursor on the laptop I'm using (since mine is well the patient not doing so well) just does an infinite loading circle.
Thank u :)
Hi, great video tutorial with amazing tips and helpful information, well explained easy to follow and understand. I need to try this on my Lenovo t460s, do I need to remove the cmos battery during the process or it’s just the 2 main laptop batteries inside? Thanks in advance.
I would suggest to remove both batteries just to be safe.
Hi miyconst, my atermiter x99 shows code 61 and just stays and does nothing. Do I use this tool to refresh bios?
hola. intente todo y no me reconoce el chip. ademas , al conectar el programador pone el display FF y hace un pitido(ruido) muy fuerte. que podria ser?
placa huananzhi x79 2.49, v3.1
my chip is 32 mb but the bios i downloaded from the gigabite website is only 1.41 mb, i cant find the correct bios for GA-78LMT-USB3
Hi, i would like to use this to reflash my bios that is suspected to be infected. But i am worried about thsi programmer whether it itself contain virus(like badusb) or the driver itself. And i would like to ask if reflash the bios can remove the virus thanks
I'm a bit confused? Would I be able to just disconnect power cord to pc, and press the power button multiple times to get all the juice out to then be able to clip the bios programmer on?
Without the need of disconnecting the cpu?
Yes, you don't have to disconnect the CPU while flashing the BIOS.
The Surfaces from Micro Soft are seal units with no coin batteries in them. The one I have just might have a SSD that can be remove or not. Think of Surface screen that sits on top of a battery and a Mother Board. No moving parts (maybe a fan) the screen is glue down. The BIOS lock is separated from the regular password.
Then I am afraid you need to bring the device to a workshop.
Hello what about hp bios files .exe it gives 4 .bin files if i choose to make a copy on this pc. which bios file i choose?
hello, i bricked my x99 board bios and now it wont boot, i tried following this video but multiple things happen:
1. at first the program said Error connecting CH341(-1)
2. after removing cpu it said in the console 4 parameters which were all ffff or 0000 so i kept trying and nothing happend
3. the run led on the programmer became yellow and now its yellow even when its not connected
any help would be great as i am stuck with a bricked pc because of a stupid mistake i made
My bios chip (Winbond W25Q256JVEQ) doesn't appear in the "IC" of AsProgrammer... What can I do? Thank you.
hey! Phil's Computer Lab made a vid about x99. he mentioned you 'cause of your unlock turbo boost vid! :)
That's nice. Could you please link me the video?
whoops, confused his name with Tech by Matt's. lol!
ruclips.net/video/hpUDGdDq4VQ/видео.html here's the vid
Awesome tutorial mate. I'll have to try it when I get my ch341a. Only on question the ch341a is 3.3v and the datasheet from the eeprom chip says it needs 1.8v so I also ordered a adapter for 1.8v but I don't know how to connect it.
Install the adapter into CH341A and the BIOS connecting clip into the adapter, it's simple 🙂.
ok.. but how do you put the device itself together in order to start this whole process?
Hi. I have Problem with writing/programming.
I have a Gigabyte ga-z87x-d3h motherboard and BIOS file is Z87XD3H.F9. Power is connected (to mainATX and to ATX(CPU)12V 2x4). XEON processor, Clock battery and ddr3-memory (4pcs) and system fans are connected to mobo, nothing else.
I have read both BIOS CHIPS (it is multiBIOS MX25L6473E), reading gone fine and both chips are full of FF(empty).
BUT when trying to do anything else with Asprogrammer 2.1.0.13, it did not happen:
1. Erace IC, it starting to do but never end
2. Program IC, starting to do, no progress in bar (red and yellow lights are on)
No error messages, but this never ends.
Can anyone help me?
Problem in machine is that suddenly it sopped working. When pressing power button PSU starts and fans rolling couple of seconds. Then all stops to start again etc... I tried to reset bioses first by short-circuiting those...
Thanks for this guide, it is very clear!
Can you tell me what is the kllisre x99 d8 chip? I bricked the motherboard but I have the usb programmer xd
Had a mobo with suspected by BIOS. Backedup up both main and backup bios. At that point, the SOP8 clamp wouldn't attach to either of the BIOS chips anymore without me holding it and I bricked my board. Gotta order a new programmer now and hope this one will actually attach AND stick properly... what a hassle. I'm so frustrated.
Just take it easy, step by step and you will get it done.
Great precise video. Clear most of my doubts. What about the 3.3/5.0 volts issue/mod I have been reading about?
I suggest you to buy the new updated version of CH341a that has a voltage switch, no mods are needed in that case.
Hi guys. Someone can tell me how to make a usb stick to run on a usb port if was disable ,without to have acces to the pc ? I got acces only to the usb port by when I insert the usb stick is not running . The power is on the usb but is not making connection. Pls Someone tell me if is a way how to do it
Hello, if chip written Winbond 74M12JWSIQ 2138 , what size it is?
I got my X99-TF bricked and with this tutorial I was able to fix it, than you Myconst!!!
By the way, is there any place to learn in detail the different versions of the BIOS inside your tool?
Having the CH341a here, makes me want to make some test but I would like to know what is the difference between one and another.
Mi899 has a description for every BIOS option. You can launch the app and pick the BIOS you want. Beware: multiple BIOS flash with CH341A may break the BIOS chip or its legs.
Hi Marlon, I have a laptop that is bricked. I need to get a .bin file to use with ch341a. any idea on how to convert .exe file to .bin file for flashing?

i have a gigabyte Z97X-UD7 TH board and when I press the? button all I get is an ID FFFF error I don't see a window popup. please help. (i got full RED LED so the full power is available)
Hi there. If you live in Sweden, you can ship or bring the motherboard to me. Otherwise I am not sure how to help.
anyone help?? Chip eraring completed, please check is empty!
i did detect the chip, i cant get mobo working
i watched another guide video about flashing bios with the ch341a and in the case of a soldered chip that requires the ch341a to clamp on the chip directly he said that we should remove all power connectors off the motherboard also remove the cmos battery , he said no electricity should run through the motherboard during the flashing
That's the ideal condition, but since the BIOS chip soldered on the motherboard is attached to another components, your programmer's power might be not enough to read-write the chip. Thus the extra PSU power might be required.
Hi!! I have a Sager NP9870 (Clevo P80DM-G). When I bought it, years ago, it came with just one GTX 980M. So now I bought another GTX 980M in order to make them SLI. I asked for them to send it with 1617 ID but they sent me with 13D7 ID. So I couldn’t flash it right with the vbios from the older one using Nvflash. I forced with the Nvflash mismatch version and the bios chip got really messed up. So I bought spares from the same chip (MX25L2006EZNI - 12G) and spare one from the older plate (25Q20BT) and ended up dessoldering the chip from the new one and putting a 25Q20BT in the place (with the vbios from the older one flashed inside using CH341A SPI flasher). When the new 980M arrived, the notebook didn’t even started if I put it in the master slot. Now with this modification, it goes to the windows all right but I don’t get image (not even through HDMI). So the idea here is to have both cards with the same vbios and ID in order to make them SLI. The notebook bios recognize both cards but the windows just the older one (with the 1617 ID). What can I do to make this work as SLI? I have my notebook with windows 10, both cards (the 1617 one is already inside of course), SLI cable, both heatsinks and even that cooper plate that was hard to find (I have the two necessary units). I have the CH341A SPI flasher and adapters to use the right voltage. And I have a couple units from both chips (MX25L2006EZNI - 12G and 25Q20BT. The 25Q20BT is so much easier to solder and it is the same model that the older plate uses. And I tried a lot of the drivers version from Nvidia and nothing, even cleaning with DDU. Would you help me to make it work? Appreciate it and thanks in advance. I really hope you can guide me to get there and I don’t think I’m that far away!!
I am sorry to disappoint, but I can't be of any help here. These notebook Nvidia GPUs are complete miseries to me.
@@Miyconst I tried to find information on how to make the new one have the same ID from the older one so the drivers and G sync work all right eventually. No success so far.
Where is the docu for the jumper switch and pin row ?
Hi, I have a question. Maxsun b450m challenger is supports Ryzen 7 1700 but , in product page it says it requires different bios for that . But in the official website Ryzen 1000-5000 series requires *B1* bios . I don't if it has the latest bios then I put a Ryzen 7 1700 is that going to work.
Each motherboard has its own BIOS with a list of supported CPUs. If the seller says that you need another BIOS for R7 1700 then most likely it's true.
@@Miyconst seller said latest bios supports Ryzen 7 1700 . But the product description that need different bios. Can I buy it
Take screenshots of the conversation with the seller and if the motherboard doesn't work with R7 1700 - demand compensation or return the motherboard. I cannot guarantee you anything, it's not me who sells the motherboard and it's not me who writes the description page. 😃
Can you remove or disable computrace using this method?
This is great. Can do a video of the rig frame you have. It looks interesting. How to DIY it?
Here is a short video about my test bench (frame): ruclips.net/video/3E7amlkqxgs/видео.html
Great video. Just wanted to know how to place the pins of the 16 pin motherboard to 4x2 pins set and insert in the programmer pins. Using the green chip. I want to solder the 16 pin bios chip on green chip of programmer and insert it into the programmer
It's hard to explain without a picture, but you just follow the key, usually marked as 1 so it matches in all connecting parts.
Can CH341A write the bios on the following chip 'Winbond 25X/Q Series'??
Yes, as far as I know.
