Asus Tuf Dash F15 (FX516PC Rev 4.0) IC chip no longer able to be read

[aprilmixtape]

I recently ordered a CH341a to try and fix my 2021 Tuf Dash F15 after seeing a video about Asus laptops being diagnosed as having fried mobos when they have corrupted bios. After following the steps from a YouTube video and flashing the IC chip (W25R128JVSQ; detected as a W25Q128BV on AsProgrammer) the laptop booted up for the first time in 2 years. I looked around my room for the M.2 drive I had removed from it and as soon as I came back the laptop had turned off. I assumed it automatically turned off due to inactivity but when I pressed the power button, the backlight and power button would glow for half a second and then completely shut off. I decided to read the IC again and compare the MD5 hash with the .bin of the bios I flashed and noticed they were different. I decided to reflash the bios and check if the laptop would turn on but I got the same split-second boot, then turned off. I decided to leave the issue for the morning as it was already late by then but when I came back to it, the laptop's keyboard backlight no longer lit up when the power button was pressed and the only light was from the battery indicator which glowed a solid orange. I then spent 30 minutes checking capacitors with a multimeter and none of them seemed to be open. I then went back to try and reflash the IC but I got the error

"Verifying memory...
Verification error on address: 00000000
Execution time: 12:00:00 AM"



I tried reseating the clip, using a different USB port, using a USB 3.0 port instead of 2.0, and unprotecting the IC, all of them yielding the same error message. I then tried using CH341a Programmer Version 1.18 and 1.29 which would either give me the error "Write Operation Timed Out" or "Chip Main Memory with the contents are in disagreement"

If anybody knows a way to fix this issue or the cause, it would be greatly appreciated

You need to get another 16MB winbond chip preferably with the same suffix as original and try flashing it.
However, i strongly feel that the symptoms may just repeat itself. I feel its the heat at play while de soldering/soldering the eeprom chip.
Look what is near the bios chip.
I dont find CH341A reliable at all. It often gives error, even writes a chip without error but it doesnt work. the same chip when flashed with RT809F/H programmer ,works flawlessly.
If you dont have any other programmer,,try latest version of "NEO Programmer" software with CH341A.
