Anyone knows what are the correct settings for the status registers here for GigaDevice 25R256DYIG on Latitude 7420?

Not sure why, I don't see zip archive with the bios attached to my previous message while I am not logged in. Uploading the dump in rar format once again just in case....Leave a comment:

Attached is the file, can you please check it?
Latitude 7420
Service tag HF8DGK3
Bios chip: GigaDevice 25R256DYIG
One more question - I read the chip using CH341 programmer and it works as usual, I can erase it ok, but when I start flashing it with an original bios, the process hangs the programmer (tried AsProgrammer and NeoProgrammer both programs just hang and stop responding). If i stop the process and read the chip again, I see that only some blocks of the firmware are written correctly and then all the subsequent memory is empty. Did you ever meet such an issue?...Leave a comment:

Hi, I have the motherboard with the exact same model: GDC31 LA-K371P, rev. 3.0. ( A02), but the UC2 chip is different from what you mentioned, it's GigaDevice 25R256DYIG, is it correct?
I will desolder and read it, I assume it's just another manufacturer, but the same chip and the password is there....Leave a comment:
