- Important Update! Check out 3.3v voltage fix for this device. It can help to prevent possible use issues like with reading or programming a target BIOS chip, or in the worst case prevent possible damage to the target device: • CH341A Important 3.3v ...
So some time ago I was messing around with BIOS modding and BIOS files. I was trying to give unique names to old 775 motherboards and accidentally broke my backup ASUS P5E3 Premium motherboard. As the motherboard has only single BIOS chip and it is a soldered one, and no BIOS flashback utility the ways to get it working again are quite limited. The motherboard does have some built-in recovery thingy but I couldn't get it to work.
So the easiest way to fix a motherboard like that is to obtain an external BIOS flashing tool. Popular ones that I know of are the CH341A that is easily available from China like from eBay for example, or Elmor EVC2. I got the CH341A earlier so used that one in this case. The external tool connects to the target BIOS chip with SOIC8 test clips that are quite hard to attach correctly.
You need a separate computer to flash the target BIOS chip with. I recommend using a laptop and the NeoProgrammer tool I discovered at the end of this project. The flashing procedure might take a while so don't get confused if it is slow.
CH341A is available on eBay: www.ebay.com/itm/EEPROM-BIOS-...

I wanted to say thank you sir, for a very helpful tutorial. I wanted to upgrade my CPU, which required a bios update. Which I had done before, this time around it failed(simply turned itself off mid-update), and I used your tutorial to a great success! I have you to thank for saving money from having someone else fix it or worse buy a new board! So I want to formally thank you!
Hello, please help me :( did you use .bin file or .rom file because I have a b450m aorus elite and should I download the bios from the official website or what :(
Thanks, this may be something I need very soon. My Asrock X370 Fatal1ty is about dead like its name implies, haha! About 100x tries to get it to boot (swapped CPU, RAM, integrated graphics only/external GPU, button battery, etc). Thankfully if I leave it running it works fine, but its very sketchy when booting back up (got it just now after 2 hours of messing with it) and that's the biggest flaw that I hate about that board is it doesn't have a replaceable BIOS chip and Asrock is a little buggy when it comes to making BIOS in the first place before I get my hands on benching with it. Thankfully I think I have that flash tool already so if it finally goes I'll have to try it (looks like I bought it 3.5 years ago, and warranty is 3 years, go figure, haha!)
Thanks Luumi! Happy benching!
Wow! I haven't seen that type of board in a long while. Brings back memories of my old DFI-Dark mobo.
I love P5E3 Premium.
@@LuumiJuhani Yeah, that mobo is sexy as hell. I remember a friend who had one and his CPU cooler was a Zalman circle, wind turbine like cooler.
This is so cool! I'm considering doing this, since I bricked a board as a first-time builder. I think the USB BIOS Flash feature went wrong and it ended up in a corrupt state. I love the idea of getting into the nitty gritty of how my components work.
This video from you, too funny. As in coincidence that when I was trying to install XP and 7 on the dark board, the bios chip died. Evga sent me a new one. Once I get my oc room finished and all set up I'll join your discord.
Awesome Video Man, Thanks for posting!
Thanks man recovering my modded M9A bios now, don’t have the BIOS solder mod 😂
Thank you for explaining it so well.
Good job, great video.
Enjoy unlimited bios modding. ♥️♥️
Nice. The hard part is always finding a bios to recover to, do you happen to know of any online repos/sites with old mono bioses?
ASUS usually has them available.
@@LuumiJuhani Huh, I'd never have thought they'd have them for older mobos.
You can actually use carprog thingy to read all that stuff
Old car ecus has those falsh memories, eproms, eeproms, all kinds of data storage. And the carprog thingy also has lots of adapters for connecting into them
@@MokokoMokoko ok
Very COOL stuff! thanks for this!
Hi, great video, but when you buy the CH341A, is it originally programmed for your Bios (make, model, etc) or is there a reference for each different Bios?
The CH341A is just an interface device. You have to actually find and download the correct BIOS firmware.
@@SkeeterPondRC For lenovo b51-80 laptop can work this metod? I have a motherbord with corrupted bios.. Thanks
@@Fabio-ik5erYou need to check the bios chip
Thanks! After 9 years i can use my pc .i am going to sub you and like
Thank you! I did learn how to install the programmer and clip on the IC tho.... question....
I'm trying to flash a Hisence 65H9EPlus TV, IC is MXIC MX25L1606E, I made the programmer read the file and saved the backup to my desktop, i'm ready to do the flash....
Question: where do I find the bin file for this model? I just need the last step to complete the flash......
Thanks for this video. I have a problem with my laptop BIOS (it won't start after a failed BIOS update) and after taking the board out I have identified 2 chips which could be the main BIOS. One is a Macronix Mx25L167E and the other is a Winbond 25Q3 2FV S10. I have just got a CH341A programmer and I have managed to read the Macronix chip and the Winbond chip. So far, so good. How do you identify which is the BIOS chip as there are no markings on the board? The Macronix chip is nearer the CPU and the Winbond chip is near the edge of the board next to an ITE chip? Thanks in advance!
so you need a windows or linux lappy for the bios chip flasher CH341A chip USB adapter device to even function???
Thumbs up for your successful hard trying..👍
I got one of these to try to repair a graphics card in case the vBIOS had corrupted, and yes, the alligator clip is beyond fiddly to clip on the chip
Please after plugging in the usb to the laptop do you still need a software or any bios to flash it or
Recently i bricked my gpu with a non compatible bios and i fixed it using this method.
Thank you so much. Does this think also work on UEFI. on this motherboard msi 170a gaming m3? And how i will know bios is succesfuly flashed? Thanks for any help.
Hello, would this tool work to flash a modified BIOS on a laptop that has a security to prevent modified bios to be flashed with afuwin? Thank you!
thank you great job done for this helpfull video
Im debating whether to do this or solder a new and programmed bios chip... What would be easiest i wonder.... ?
hi, i run into an issue when clipping to my bios chip. windows and programmer software stops detecting the usb programmer then states usb device malfunctioned. like if it shorted the usb. ive checked pin 1 connections and adapter to usb programmer and they should be correct as every video ive learned from. any ideas. drivers a installed usb recognized. but once i connect to the chip it shuts off the usb. (no pwoer on board no cmos batt)
@Luumi Those CH341A External Flashing Tools are meant to receive a chips by itself. You don't need any power to the motherboard or the chip. You are also supposed to remove the bios battery "normally". Beside that you have bin very lucky you did not fry the bios chip or the motherboard. Your CH341A has a manufacturing error. It connects 5v to the 3,3v data pins and need some soldering to be used save. Google CH341A 5v fix
And because of that problem there is a newer CH341A programmer model on Aliexpress and other places that has a manual voltage selector switch for 5, 3.3 and/or 1,8V. So, no need for a mod. Job done.
i have a question, is it working if i download a bios bin file and flash the bios chip, any mod is needed?
and boooom it worked. thanks for the video.
Thank you :D , time to subscribe !
Can you help me to get BIOS file for specific laptop to flash reset the chip. Since it is showing an error "buffer size is bigger than chip size" as the bios file is of 16 MB whereas the memory of chip is 8Mb.
Thank you for new hope. My motherboard just broke from flashing the bios. (by ASUS Software Update). I'm currently waiting for the device I just ordered from China. I hope I can succeed like you.

Hey got a question ... I properly got my ch341a working and I can read the BIOS (or what is left of it, most data reads blank) But I can't for the life of me find the proper normal driver for my motherboard. The Gigabyte website just has some exe that extracts to a few files ... non of which are hex or bin files. The file extension of one of the files end with FC ... which is the version of the motherboard. Is there another website or something where I would be able to download the proper BIOS file? Thanks in advance! (it's a very old motherboard GA-970A UD3)
What if my bios file is .10M extension not .bin msi ge600 1675 model old laptop...😔😔
I need to do this with my thinkpad t15 but I searching for the bios file. on lenovos page there is an exe file you can extract it and then there are 2 files in a folder 1mb~ and 24mb~ I think there these but I don't know if it's correct
I have the MSI B450M pro-m2 max motherboard, i wanted to upgrade my cpu from 3100 to 5700X. I have to update the bios to be able to use the 5700X, but in the middle of installation it corrupted, Now everytime I turn on my PC the cpu debug led it turn on. I've tried everything (clear cmos, -changing the cmos battery, take out the CPU and re-inserting it back, etc) but still doesnt work. Do you guys think by flashing it with CH341A will fix the issue?
Best to connect via the SPI connectors. I did that for my Dell bios recovery.
Hi, how can I do that? I can't find any thotorial for that spi connection. Can you help me please?!🙏🙏
should u take the CMOS battery out?
Did you just downloaded the bios from the Website of the Manufacture?

i tried doing this but the software to use to flash the bios didn't have the current bios chip model i have
is this work with asus eufi bios i want to try on my asus x470-f gaming? Asus newer motherboards hawe some strange file format for bios ...its not .rom or .bin its .gap?

I overheard somewhere that the CH341a is spitting 5v out its data line, instead of 3.3v. Is it necessary to mod the programmer so that it spits 3.3v?
Under load it drops to 3.3v
thanks & very good
Good morning, sorry to bother you, but I have seen that you are an electronics specialist and I was wondering if you could give me some solution. I have a Sindoh 3D 3DWOX 3D printer and when I inserted a USB flash drive to update the firmware, there was a power outage. Now only the Sindoh presentation screen is displayed and the image is frozen there. I have disconnected the printer from the power and even removed the internal battery from the motherboard but it remains the same. There is no way it does anything. It has been left frozen. I'm afraid the firmware has become corrupt. I have observed that the motherboard has some jumpers, I don't know if any of them have any use. Can you help me please? Any suggestions to force flashing the firmware? How can I find out which chip on the printer's motherboard is the EEPROM? Thank you very much in advance.
Chip quick or hot air will remove the chip, but it is necessary to have pretty advanced soldering skills and the right tools. I have desoldered bios chips from graphics cards because of the clip not gripping good on board and flashing them with this excellent flasher. Thanks for the video.
it's also got an ISP header right next to it, which should make light work of the problem..
@@TheducksOrg what’s that
@@phr3ui559 ISP = In System Programming. Allows you to reprogram the chip in situ

Neo programmer constantly says IC not responding when i try to read the bios, is there something i am missing?
Just a fun tip, EVGA mobos have 2 bios chips per board with a switch bios 1 bios 2 selector switch so if 1 is corrupted can use the 2nd one to boot into windows still
Modern boards have even 3 bioses but not all have a removable BIOS chip.
. @LuumiJuhani I wonder what made you say in the video that this chip is not removable? Any 8 pin chip in the world is removable with the right kind of tools and skills. Tip: to avoid melting plastic parts or other electronic components situated in the vicinity of the chip while using the hot gun to desolder the cip simply use some capton tape and that is heat resistant and will protect them from burning.
Nice video
BTW how to recognise 24 or 25 series of the bios?
its in the cryptic name on the chip i think
@@smilingbandit6900 what kind of cryptic answer is this?
any advice on how to make good contact with clip on chip? Feel like i have been trying for days
Yeah it is pretty difficult. One way is to remove the chip from the motherboard if its a removable one.
Greetings, the BIOS flasher w/ Test clip to flash BIOS and EEPROM chips is an interesting resolve I being clueless such a fix existed. Considering I've been spending endless hours attempting to normalize my corrupt BIOS that invaded my gravity standing sideways.
I have a dysfunctional Lenovo YOGA 730-15IKB Laptop, question; Are the flasher Test clip Devices universal for all computers or device specific for specific model computers?
Thank you very much for posting a vital answer for this educational post for all of us, remain well in peaceful balance to take good care of it all...
There are clips for any 8 or 16 pin bios chips.
Bit late but how do you know what the bios chip on a motherboard?
I had a p5e3 deluxe / wifi motherboard and the same problem happened to me, but I didn't have Windows for this, and I executed these commands with flashrom installed in my Linux and my problem was solved(just be aware that whenever you encounter a problem or error at any stage, you should Run the following commands again from the beginning, because if you don't do this, the motherboard will not work despite the correct information in BIOS and you will end up in bootloop!)
flashrom -E --programmer ch341a_spi #erase BIOS
flashrom -w 'bios file location ' --programmer ch341a_spi #write and verify BIOS
flashrom -v 'bios file location ' --programmer ch341a_spi #verify BIOS
your bios should work again 😉😉
please help sir where can i download bios file for acer e5-475-35cl rev e bios
Thanks for the video!
I might've just messed up flashing the BIOS on my motherboard.
I happened to have the USB programmer already, so I just ordered the required clip. Once it arrives I'll give this a try.
Seems like the most important thing (other than getting the clip to contact the IC pins) is to connect the red wire to pin 1 on both the IC and adapter, right?
Where did you get the ROM file of your bios? I have MSI X99S SLI plus and i can't find the rom file for it
From the manufacturer's website, where you can get all BIOS files and drivers.
@@LuumiJuhani .rom files are not available on website. I get some strange format files *.100 file format. Is it possible to use it directly with CH314A?
@@AhmadAlghannam I think you can covert to rom.

Will this work if i have a board with a working BIOS? (Like read the BIOS off the working one and wright it to the corrupt one?)
Easier to just download the bios file from the net and write to a corrupt one.
Question. I have a bunch of chinese motherboards and I cant find the most recent bios for them. Around half of them are causing major issues as a result of the bios being out of date while the other half are fine. Would I be able to copy the bios off 1 of the good boards and flash it to 1 of the bad boards if they are all the same model?
Yes if they are all the same model. Read the newest bios that works store it and reflash the bad ones. Done.
Please Help me . I need to Flash files Download links for Laptop and desktop PC.
Why would it ever be necessary to turn on the board ?
If you remove the bios chip and solder it to a breakout board, it works fine, so why would you need to power on the board ?
Because the CH341A may not power the chip.
If the motherboard doesn't appear on the screen and beeps, what's the problem? what is the bios? Biostar A88MQ motherboard 😁

Please Help. Hi, I have Dell XPS 15 L502X {2nd-Gen i7 processor & windows 10} (purchased in 2012). Few days ago, a blue screen error suddenly appeared during using the laptop (not remember the error code). After that, repeat blue screen errors occurred just after the windows completely load up but Windows was loading in safe mode.
Next day when I tried to boot the laptop again, it's fan, leds lights & keyboard backlight etc are working but display is not turning on at all (Not even Dell boot logo is showing). Battery & charger is ok.
I have done all basic troubleshooting steps like press power button for 1min without battery & charger. Also connected the laptop with external monitor but no help.
Laptop Display is working, i have done Dell Display test by pressing "D-key + power button" and multiple colors are showing but after reboot same black screen issue is happening.
During repeatedly trying to boot the laptop, 2 times Dell boot logo was randomly appeared out of 50 trys. And an error code was showed on boot " 00c08270: Real time clock error - check date and time setting" along with continuous beep sound.
I pressed F2 to boot in bios and changed date & time settings and then I pressed F1 to boot in windows. Windows was trying to load but a blue screen error occurred " Stop code: DRVER POWER STATE FAIURE" .
I thought that it is CMOS batter issue so next day I changed the CMOS battery and installed a new one. I also removed the RAM, Keyboard, HardDisk and cleaned their connectors with soft brush & cloth.
But issue is still occuring, Dell boot logo is not appearing again & display is totally black but fan, led lights, keyboard backlight etc is ON. I am not able to access BIOS settings.
Is this problem related to BIOS? (but I hadn't installed any bios).
So, What can be the issues & how to resolve it ?
possibly bios
Was this just a test or are you really gonna use that old thing? Core 2 duo?... yeah that's pretty old.
vintage core duo sir
yes it is helpful ;D
Super.
If I have a removable chip, can I just pop it straight into the USB programming device?
i have mobo which blank when install ram

Very nice little tool
where did you get rom file
From asus website.
If the SPI header is on the board you don't need the clip.
What do you mean please explain?
what is that
Serial Peripheral Interface (SPI) is a series of pins or connectors on the motherboard that are used to connect the different chips and the programmer hardware, Not all motherboards have it.

Eso está mal. Si te fijas en el diagrama esquemático el circuito CH341A esta alimentado a 5V. por lo que la lógica esta a 5V no a 3.3V que es como se alimentan este tipo de memorias y además si alimentas esa memoria en 3.3v y le metes las lineas lógicas en 5V podrías dañar la memoria y targeta madre de tu PC.,
*What about using the 1.8v adapter? I hear 5v is too much for BIOS chips and can fry them without using 1.8v adapter!*
Although it’s recommended to match voltages, even with 5V it’s just 1ma current. Never seen anyone fry a chip with 1ma. It would be fine as long as it’s plugged in properly and doesn’t get too hot.
In my case after i update the bios i have no display, i try to rest the bios by removing the battery but it didn't help
If i use this way do you think it can fix my motherboard

@@yukuzoona6604 yeah it worked! but you need to take off and put the bios chip back again, the thing that they give you, that you put on the chip doesn't work so you need to take it off the motherboard, you need someone who has got the things to do that

I bought from ebay.
Good jobb, by this programmer get 5v to chips this is danger for to BIOS and EEPROM.
its better to desolder en programm it using a adapter
dude, do you realize that this SPI header was for BIOS chip and the clip hassle was unnecessary?
Exactly :) this SPI header is connected directly to BIOS chip. Only need to check with multimeter (I realised that pinouts posted on the internet aren't always true) and connect those pins to programmer. More reliable than the clip. Also beware the voltage on the chip. Mostly spi flash is 1.8V so you need to plug adapter to CH341A programmer.
