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.

[@AJDOLDCHANNELARCHIVE]

@@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.

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.

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.

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. 😃

9:13 If you have an option to "Safely eject" CH341A - you can do that, but in general, it's safe to just unplug it. 9:52 I just said, that there are some more features in the AsProgrammer application, but they go above the minimal usage guide.

Nice video, thank you. I noticed that is some videos referring to some laptops (eg mine HP Elitebook 840-G6) it shows the Bios chip having to be removed from the motherboard and I didn't really understand why - has that to do with powering the motherboard or not during reading/writing? Could there be some other reason? Thanks again.

That's exactly because of the motherboard's layout and risk of burning some components when power goes from the chip to the motherboard.

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.

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)

[@xx3868]

I looked up my Bios chip for "max ratings" and it says 4.7V Peak only and Reg V way lower SO, the little programmer outputs all 5V unless you mod it down to 3V and the specs for it says it can do that so i will me doing mod as old bios chips only meant to get 3.3v on its lines and you can install a switch to toggle from 3.3 to 5 as well. Max rating are VERY critical as i once accidentally touched the 19V pin to the LDV pin and it sent 19V into that line of the BQ chip and then the the chip only pulsed voltage and nothing worked. Looked up the max rating for that pin and it was only 7V, so you can see "guessing" that 5V wont hurt a 3.3V bios chip MAYBE you get away with it or not, too risky. Volts is pressure so even if the signal lines wont have any amps on it, they tell you what pressure it can stand too and exceed that and you compromise the chip.

What about programming using the SPI header on the motherboard, can you talk about that?

[@Miyconst]

If your motherboard has a header for programming the BIOS chip - you can use it, but not many boards have it.

[@aoi2853]

@Miyconst but do you connect PSU in that case? Another person who used SPI header told me to remove CMOS , disconnect PSU and power drain the PC

The less power the better but sometimes it's required to connect a PSU.

Using UEFITool open the capsule file just as a binary BIOS file, then in the top contextual menu there is a Capsule section, select there "Extract BIOS" or something like that, I don't remember the exact name. It will save you the BIOS itself, without the extra capsule info.

All i want is playing fornite&some other game, meet people online and maybe becoming friend. Only that is what i look up for everday. My life suck, my parent always fighting over something, they blow out their money having fun when young and now have none saving and only debt that i and my brother gotta contribute, because of how much they fight... It affect me from very young and i have become stranger in my own neighborhood, feel really hard to make connections with people. About a week before this happen, my gpu suddenly no display... Idk what cause that. But man... that alone is very suck cause i cant play games, gotta pay to service that gpu using almost all my money at the time and even now i still havent received my gpu back. I have suspicious its my psu cause my electricity went out few time back then and i heard many people complain its damaged their electronic, but with my motherboard now error i guess its not only thing i gotta worrying.

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?

[@SaajidRizvi]

Can you remove or disable computrace using this method?

[@And10686]

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

[@Miyconst]

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.

[@dalavaisri]

bro, awesome tutorial. I have surface pro 3 which is locked at boot level. cannot even go to boot setup as well. right after boot screen it asks for password. is there a way i can flash the bios without opening the surface pro?

[@Miyconst]

I am not aware of such a way. If you can't even enter the BIOS then I have no clue what else you could do.

Hi, I am trying to flash a bios for a lenovo ideacentre AIO 520-22AST it has a W25X20CLNIG bios chip. The bios file I got from the manufacturers website is too large for the chip. The chip is 2Mbit but the BIOS file is 8MB. Could you help me finding a correct file pls? Many Thanks

Hi. How could I help you find something in Google? I have exactly the same tools as you do.

[@amirtak9886]

Asprogrammer comes with the option of 2 CH341A drivers, parallel and serial. Which one should I use?

Serial, if you use USB connection.

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.

Bro I want to reflash the bios on my dell optiplex 9010 (i5 3rd gen) I checked online ....i found a product named USB Programmer CH341A Series 24 EEPROM Writer 25 SPI Flash BIOS Board Module USB to TTL 5V-3.3V And a SOIC8 150mel Socket + SOIC8 Clip Adapter... My question is ...will these things work on my pc....I found SOIC 200mel aswell ....which one to buy... I csn share the website link if you want

[@Miyconst]

Sorry, I can't tell you what is going to work without access to your Dell. Find the BIOS chip on the motherboard, check it's model and physical dimension, then check which programmer can read/write it. Most likely CH341A can do the job for you.

[@UNR11]

Hi bro, i have asrock b350 pro4 and i dont know which version my bios chip is 24/25? I did look at the bios chip in motherboard but it doesnt show any numbers/letters. It should be 25 right?

[@Miyconst]

Yes, you definitely have 25 series, but AMD boards need 1.8V, so you can't use CH341a out of the box, you need to either modify it for 1.8V or use a special adapter.

[@UNR11]

[@fluthyer4362]

Hi great content, i have a question, being the motherboard an x79 turbo, is there any situtation where the bios has to be removed out of the motherboard to be reprogrammed or is it always possible to reprogram with the chip still on the motherboard? I have an old psu that i was planning to use for not having to take mine out of my computer but it doesn't have the 8 pin conector, do you think that the 24 pin alone could be enough? Thanks.

[@Miyconst]

Yes, 24-pin power is usually enough, you can also try to read/write the BIOS without connecting any power, it might work.

[@fluthyer4362]

@@Miyconst Nice, good to know, thank you for answering, focusing on the technical side of computer hardware on youtube as well as you're doing is rare now days.

[@TrustNo1sz]

Great precise video. Clear most of my doubts. What about the 3.3/5.0 volts issue/mod I have been reading about?

[@Miyconst]

I suggest you to buy the new updated version of CH341a that has a voltage switch, no mods are needed in that case.

[@d11k4facts5]

Can I know why the AMD b450 motherboard's latest bios not support older 1000 Cpu's

[@Miyconst]

Because there are way too many AM4 CPUs and some motherboards have BIOS size limitation so they can't add support for everything.

thanks for the tutorial..my huananzhi is the f8d plus...i bricked and need to reflash,,i saw a winbond w25q128jv is where is the ngff m.2 on the right...the first one...is this the chip to flash??i dont see on the board another one similar..can someone point me in the right direction,please?

That seems like the chip you need.

[@ErcoleBellucci]

I got B550 Pro-Art and it's not bricked, it doesnt show the bios even after CMOS and flashback bios, should i consider to do this? It helped a lot of people

[@Miyconst]

Are you sure your BIOS is compatible with your CPU? AMD BIOS chips are 1.8V so CH341A may kill it, make sure to use the 1.8V adapter if you decide to try to flash the BIOS.

hi miyconst....how do you extract a bin file from A7592IMS.1E0...the bios is the latest update for the MSI G41TM-P33 motherboard...i cannot find a bin file for the board...i am using a CH341a..it can read the bios content but cannot write in it...it gives out an error "write operations timeout failed"..please help me.

[@Miyconst]

You don't have to extract "bin" as it's just a file name. You need a binary BIOS file, that's it. If your programmer fails to write with a timeout, it will fail with any file, you have to figure out why that doesn't work. Feel free to bring or ship me the motherboard if you would need my services.

[@newvaper3794]

@@Miyconst thanks for the reply. i soldered the bios to the CH341A and is now detected...however when i write it says file length beyond range of and will be ignored..this is the correct bios for the board...please help me. thanks.

[@Miyconst]

@@newvaper3794 The "correct" BIOS does not mean that it's a binary format. Many manufacturers provide their BIOS options in a custom wrapper, which is needed to use the official flashing tools. To use CH341A you have to use a plain binary file, so you have to extra the actual BIOS from the file you have downloaded.

[@newvaper3794]

@@Miyconst thanks for the reply..what program do i need to extract the bin from the bios? i tried the uefi tool but it is saying that the bios is not of a uefi fromat.

@@newvaper3794 it's different for each motherboard vendor, so you have to research how to do that with your particular file.

Hey dude, I've run into a problem. The clip for CH341a has 4 pins, but it is too small for my 16MB Machinist X99-K9 chip: 25Q128JVSIQ I can only make contact with 3 of the chip's pins.

I had problems loading bios using mi899 before and I wrote a new bios with ch341a without any problems. After 2 months, when I wanted to change the bios again (Huananzhi x99 f8)It does not accept it.

Can you also verify the read data? If no - the programmer is not attached correctly or the BIOS chip is damaged.

It could be that your CH341a malfunctions as well, but more likely the chip is kaput.
