hi, is me again, last laptop is giving me headache. I am not able to READ or FLASH the 8MB chip, as the other ones. Is giving an error :

Pin detected passed
Check ID Error!
Checked ID is : 0x FF FF FF
Wish to continue programming, please cancel[Check Device ID] option!

I did disable "Check ID" and reading went through, but writing Didn't.

Is there any solution for this issue?

Chip is the same as for the other ones so is not possible to pick a wrong chip from the list

Thanks in advance

[moshu]

I've read the 8MB chip on the the 2nd Laptop , but Rex patcher doesnt recognize. I've read the 16MB as well, went through the patcher and the same.
Any idea what is wrong here?

in the end I've write the same patch from the first computer to the 2nd and is working

[moshu]

thanks, I've used the patch for the 8MB chip and initially computer restarted every 5 seconds Redo the soldering and is good now

Thanks again

Hello,
Now you can see how well the Rex98 software works.
The 16MB Bios chip doesn't need to be patched because nothing is found in it.
If you have 2 chips, as in your case, you have to consider which of the two should be processed.
In your case only the 8MB chip needs to be written back.

I've try link above but doesn't want to generate the patch file for the 16M chip, it does for the 8M chip instead. Below is the error:

Rex98 **Dell-8FC8-Patcher**
@Tecshack Cebu
Pag huwat ky ga patch pa!...in file W25Q128JV@SOIC8_61F0533_PSW_V2.BIN
wa nakit-an ang intel signature
Pinduta bisan unsang key para ma exit...

Please help me understand what I have to do next.

In the meantime if someone can patch both file for me
