How To Unbrick GPU & MOTHERBOARD BIOS | CH341A Tutorial

My GPU has 4 things with 8 legs and a dot in the corner. Two on the die side, 2 on the back side. How can I tell which is the BIOS?

Thanks it helped me recover my rtx3060

Update: I've successfully unbricked the gpu, subscribed and liked!

Going to have to upload this somewhere else Google refuses to allow us to download it due to a false positive virus warning.

Thanks! Gonna unbrick my gtx 1060 since it's better than the crappy 1650 I have now

Does it work with maxsun rx580 ? I am a noob but i'll follow your steps , i've bricked it :( , i've already ordered the programmer , great video , thanks

Google drive says folder has a virus and cant download zip.

Bro you're great!! Thank you so much for this, I mean how long i've been cracking my head looking for a clear explanation of this problem, you are our hero

The video is very clear and easy to understand

I followed link to download software and drivers and getting message. Sorry, this file is infected with a virus.

Only the owner is allowed to download infected files. What am I doing wrong? lol
I am able to download similar software and driver but getting the clip to stay on is a nightmare. I am so done with this experiment.

my chip is PM25LQ020 and the software wont detect it how can i save my gpu please

hey i cannot download the link it says it is infected by a virus, could you update it please? Thank you very much :)

can i do this using nvflash ????

Hey bro, i have an rtx 2080ti and the voltage is stuck at .712V with a max of 1350mhz. I have tried flashing multiple bioses with different power limits but it didnt help. There s 2000W rtx 2080ti bios , its the Galax RTX 2080 Ti HOF vbios, which has unlimited power, overvoltage, voltage/frequency control. the reason i cant flash it with nvflash is because of a different EEPROM (WBond instead of ISSI). Anyways do you think this is doable in the first place and if it is, would it be a good idea to unlock the voltage control or maybe the voltage control chip of the gpu is just dead and there s nothing we can do ?

It doesnt let me click the detect button

I've used the 341 on a hdd before and thought this was possible but had yet to try it! Thanks for confirming this!

Can i flash dead gpu in this method?

Just bricked my RTX 2070. Error code 43 in device manager. Cannot flash bios because Nvflash says no Nvidia Display Adapters Found...

You are a legend, I took so long searching for a vid on how to physically tap onto a board with pins to edit the BIOS and not some VBIOS crap.

Thank you man!

Could you help me, my gpu electricity good and chip getting hotter after turn on, original bios not corrupt, and i flash using same type bios but different date still wont display

awesome info and thanks for leaving a google drive with the software, it worked for me!

Hi great video, i have a rx6600xt red devil and the rgb leds didnt work so i see that if i changed the vga bios i would work and know i can change the color but i had some shutdowns and i lost performance like 60 to 80 percente in games but my graphic cards still work so its not another way to reverse the bios without a spi flash programmer? can i do on amdvbflash? its where i done the atualization and my bios have two pre setted bios silente and oc i have done one by one and even that i have problems; thanks for your time hope you can help me

Haha, I was wondering if you were Swedish based on your accent, then I saw your folders, gött :D

nice Video thanks for that 🙂

software for this is impossible to find

"Get some paper towel, and rub some off." That got me laughing. Lol!

Hi! I have a chip named fm25f04a but the program can't detect it, and it's not listed. Can you help me?

Coll tutorial ! Merci bien man

Your video is soo helpfull... but when the chip isn't in the list what can I do? my chip is MXIC 25U8033E. There is anyway to put it in the CH341a apps ???

Will this 341a work with my bricked gigabyte rx5600xt rev 2.0

I have a GTX 1080 Founders Edition gpu that's bricked and unable to post from previous owner. Doesn't this have a 3.3v output? We need to reduce to 1.8v for Nvidia graphics cards?

on windows 10 first install DRVSETUP64.exe or setup.exe ? which is the right file...

i'm so confuse.. i download it, it said ch341 and then sofeware.. and then i click open and nothing happens, keep asking me what program i want to open it with. so i went and download unzip thinking its in a zip file but then it won't even show me that as an option..

hey, i have a ch341a programer, doing all correctly when i connect the gripper to the bios chip the programmer disconnect, the red led on the plate seems like shine less, so searching thats for a cut, so i tested the chip and 2 pins are in 0, but i think thats pins are negative, the chip is the pm25lv512, any recomendation helps me thankss

Many thanks

Greetings and Thank you! I know this video has been out for a while, but I have an XFX AMD RX 580 8gb card, but I don't see P25021H listed in the CH341 Programmer software. Any clue which one to use? Thanks in advance.

The new GPUs have encrypted bioses that can't be written without an encyyption key present in the flashing software .

friend ... what programmer do you advise me for a gtx 1070? I understand that some work with 5volt (usb) and others with 1.8volt. (adapter) How do I know what voltage is my bios chip?

When I order one of these, will they come with the wire and clamps or needed to be purchased separately?

My bios chip doesn't appear in the software. Any solution to this?

Please does this work on a laptop

I just got my CH341A in the mail today. I was curious, how can I be certain whether to use the series 24 or series 25 pinout? My tool has both. Also, does the card need to be powered on while flashing? Or can the data be transferred while the card is off of the motherboard?

Ah, thank you for this video, I hope it works

Really the best tutorial I found. Thanks!

Dosnt work on mine it comes up the chip is write protected

Thanks! A friend gave me one of those fake 1050 ti's and I badly need to make it work for a job, coz it requires me to have a gpu and a GTS 450 is more than enough for the requirements.

Yay! This is so good! Thank you so much for this wonderful video. And for your knowledge. You should really follow your dreams 💙 then you’ll end up where your supposed to be ❤️
