@nikey22 - dump with 1.30 and 1.34 and then ASProgrammer 1.40 or 1.41 and compare them in hex, if all match then for read/dump it doesn't matter, but writes you can only find out by erasing the chip and writing your dump back to confirm it's OK
I suggest you have someone check your dump to be sure it's an OK dump, unless you know how to look in a few tools and be sure it looks at least similar to the stock BIOS and or a BIOS in general. I've not seen any issues with your chip ID and regular CH341A software, only some 128 Winbond ID's

@Hyppo - please upload for me, I don't want to register somewhere to download, as mentioned above, thanks
If you doubt it's erasing, fill the chip with data, erase it, then dump and look at the file, if it's all FF then it erased properly (or do a blank check with regular CH341A software after an erase with colibri)

@huyho - download clean versions of 1.40 and 1.41 from the source

Hi Lost_N_BIOS,
First thanka for your help, now I already can open the software. But I have chip SST26V032B seems that CH341A and AsProgrammer do not support on this chip. Can you again help me with this case?

Thanks so much!

@huyho - I assume you meant SST25V032B, any other typos there, such as maybe VF, or VF0, not V0? SST25VF032B is in 1.30 software and ASPprogramer 1.41 list too, I would try this ID
Show me image of the chip too, in case it's not actually SST. ESMT is the ones that are really not compatible, and many that are detected as SST can be PCT instead,

Hi @Lost_N_BIOS ,
I show the chip

Hi @Lost_N_BIOS ,
any update?...

That is Microchip Brand (not full SST I think, page 48 shows code info) SST26VF032B AKA 26F032B - https://www.microchip.com/wwwproducts/en/SST26VF032B
http://ww1.microchip.com/downloads/en/de...c/20005218e.pdf

I see no way to tell if it's 32B (26VF) or 32BA (25VF) type flash, both have same 26F032B on chip
Try SST, PCT, and Microchip 25VF032B, this ID is in CH341A software, ASProgrammer + Colibri too

You may need to purchase "FlyPro" brand flash tool, it's only one I see with this 26VF in compatible list, but from CHIP ID on face of chip you can't tell for sure if it's 26VF or 25VF
Also, I see REVELPROG is compatible too

Have you tried any Flashrom?

Good day,
A successful bios update (from stock to newest V.) lead to me, successfully bricking my ASUS A68hm-Plus motherboard.
The BIOS Chip is identified as a GD25Q64B but the label looks to me more like GD25B64B (definitely is), nonetheless the CHA341a Soft. reads it and i have extracted a dump.
Skimming through the thread i noticed that, there is quiet a lot more to this, than i firstly imagined.
Could someone give me directions (to a guide) that fits my circumstances and could possibly alleviate my plight?

Good day,
I have Acer Aspire S7-392 that I wanted to flash the bios chip (winbond 25q64fv) with the bios dump from other working unit. I used the CH341 for making dump and to flash. After flashin the dump. the laptop led indicator kept blinking but there was no display on monitor and the laptop did not respond to keyboard. I also downloaded the bios update file from Acer and extracted the isflash.fd file. I noticed that the file size of the dump (8 MB) and the isflash.fd (4MB) are different. I will be grateful if anybody can give advise to this problem. I attached the bios dump (acers7-392.zip) and fd file from acer bios update (isflash.zip).

Do all 8-pin SPI25 chips (eg, W24Q64FV) have the Vcc at pin 8 and GND at pin 4? Is this a standard? I ask this because 16-pin SPI25 chips (eg, MX25L128E5EMI) have Vcc on pin 2 and GND on pin 10, so I'm having to individually route each pin from the SOIC16 clip to the correct region on the CH341a Programmer.

Yes, according to the data sheet.

Hello, I bricked my asus laptop because I flashed a bios with incorrect module. Do you know how can I get soic8 and ch341a at aliexpress? After that how can I connect my hdd?

I didn't buy anything at ebay.

@XPWELL64
Which Laptop or which type of BIOS chip is it?

You can buy directly from aliexpress, they have english language, too.
If you know your chip, you could buy soic8/soic16 or dip8/dip16 and maybe also a clamp.

Best regards, MiMo

@Amorphis - Software package, in case you possibly need other general CH341A software versions - http://s000.tinyupload.com/index.php?fil...695330485827902

CH341A Image Guide
https://www.bios-mods.com/forum/Thread-G...341A-programmer << Same as one directly below, but with all images expanded/visible at once
[GUIDE] Flash BIOS with CH341A programmer

I think maybe I already helped you with this on another thread? If not, it's OK, we'll get you sorted out

@jsinfo2 - please link me to stock BIOS package from manufacturer, and attach working BIOS dump from other system, with that include dump from broken system if you made one (before you did anything)
For W25Q64FV you should use software version 1.30 or 1.34 (linked above) and ID W25Q64BV, otherwise writes will fail usually. If you have not touched (written or erased) the BIOS on the broken system, make a new dump with this software version and ID, and include that with above instead of the older dump you made.

@XPWELL64 - you can purchase on ebay if you want, or any store. You need CH341A + SOIC8 test clip, be sure it comes with cable (Some ebay sellers show cable but do not include)
In above linked guide you will see how to use these tools to connect to your BIOS chip (not HDD)

Does the green CH341A works with the test clip? (to read/write without desoldering)

I read that this varies with the board. But I saw a random youtube video where a technician says that the test clip won't work with the green programmer, only the black one.
Then I saw this message that suggests the same thing:

[quote=Lost_N_BIOS|p57684]...*EDIT PT.2* I've been messing around with it for a few hours, now I keep getting the chip detected, but only in the versions of the program which automatically select the name of the chip. In the one that makes me choose I still get access violation.
I can read the bios but I only see FF in the code of it. Anyway, on the left I Have theese informations:...

Which CH341A did you use? Some of them didnt work at all, they use wrong 27Mhz crystal instead of correcf 12Mhz crystal.

I have CH341A in different colors. Black CH341A is able to read data via test clip, my green CH341A isnt able to read via testclip. But both of them read the chip correct if it´s put in the zif socket.

So best is to try to read another chip and take a look if you can read data. If yes then maybe the current is to low to power up some parts of the board.
