HI friends,

I really need help because I am a little bit desperate. I am trying to fix my son's computer because we cannot afford to buy another one.
I have desoldered de Wson8 (25R512JVEN) Bios Chip, however I am not able to read it with CH314a programmer (Neoprogrammer, Ch31A program, AsProgrammer...)
Also I have modified Ch314a programmer 3,3V but same result.

I attach you some pictures, I don't really now If I am doing anything wrong.

Please help

you have three different files because you read them with errors..
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

The 3 files should be identical, otherwise you are doing something wrong.
What is the chip number? Need to see which adapter do you use with the Programmer?

25R512JVEN and I am using T48 programmer and Wson8X6 adapter. (Forget previous pictures of CH314a... in this thread).
I think i am doing well but unfortunatelly this chip is corrupted.
So I need a bios to write in a new chip

Here is your new BIOS, try it and let me know.
If you want to replace the chip, I think you need to use a similar one "25R512JV". Also you have to choose verify after programming the chip to see if the written file is identical or not.

Hey friend, i wrote this bios in the chip, read after the writing everything is correct but my laptop does not work, same situation at the video posted before. Led turns on and after 10 or 15 seconds It turns off. Maybe is other problem i am really desperate
