Exact the same Chip on TBook 16 Power, same Problem. It can’t read (everything is “00”) and after every write it complains a mismatch because it still reads “00”.

Yes, I did and the Act LED ist actually flashing when I try to write or read. It also tells me there was a timeout if I try to write without the chip connected to the programmer, so it is finding it.  But when I click “Detect” it didn’t choose a chip (I choose GIGADEVICE GD25Q64, also tried WINBOND W25Q64) and the Manufacturer Information an Capacity all showing “00”.
It pretends to write, but when reading I got all “00”. Should be “FF” if it’s erased I think…
Next step is to desolder the chip and try it again without the Mainboard connected.

The Battery was disconnected while I did this btw.

I got bad news again…

I am able to connect the flash chip to the programmer but I keep just receiving zeros…

When I flash it the software tells me that the contents dismatch with the file (because there are only zeroes) and the tablet won’t boot.

I really hope I can get this thing back to work somehow

Thank you very much! I think this Little file could save me.

I noticed that I’ll Need a Level converter (1 .8V) in order to not blow the chip. It hopefully arrives the next few days. I will provide my results when I’m done.

Could you please Backup your bios and attach it?
I made a Backup of mine but it’s on the internal Drive…I hate my self a bit…

With this tool you can “Save” your bios to a ROM file. It would be very nice and I would love if you do this.

My USB Programmer arrives tomorrow and I just need the ROM.

 

EDIT:

Maybe I should tell you how to backup the bios easily to save you time. In this downloaded .zip file go to “AMI AFU for Aptio V/afu/afuwin/64/” and extract the “AfuWin64.zip”. Inside this zip there is a “AFUWINGUI.exe” which has to be launched with administrator privileges. It instantly Show your Systemdata and offers a “Save”-Button which saves the bios to ROM file.
