I am a newbie when it comes to flashing. I am using TI866 plus and a test clip to connect to the chip MX25L12873F. I am able to do the following. Read the chip. Save the bios backup file. Then open a "t460.bin" file which i downloaded from the internet, did an erasure, then program. However after that, I could not turn on the laptop.
After which, I tried to open the bios backup file, erase then program. However, I could still not turn on the laptop.
I tried to do the comparison between "the read bios chip" and the "backup bios file" and found out there are many differences. Is this because I am using the test clip which is not good?
The file "t460.BIN" has both BIOS & CSME corruption so if you flashed that, then that's why it doesn't boot.
You must not take dumps from the internet and flash them directly on your SPI chip because:
a) You lose model specific info (serial numbers etc), part of the BIOS region b) The CSME firmware is Initialized and needs to be cleaned first via [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization c) It could have a BIOS which is corrupted, modified in a bad or unwanted way, infected or similar
You have not mentioned why you're doing all this. What was the original problem?
