Hello, I was wondering if anyone would mind helping me with an issue I'm running into with flashrom on a dell xps 15 9550. The dell has a 16 mbyte Winbond W25Q128.V bios chip on it. I'm using flash rom on a raspberry pi 4 but when I read this chip with a soic8 test clip, it seems to read successfully. However, when checking to see if the checksum of the reads I do are identical, they always come up as different values. The other two bios chips however read with the same checksums every time. I am attempting to use intel me cleaner to set the hap bit and disable intel me without repartitioning or cleaning anything on the chip as intel boot guard is enabled. ME Cleaner is able to read the file and say the hap bit has been successfully set. However, when writing the modified image, I get the error through flash rom verifying flash...failed, your flash chip is in an unknown state. The laptop will no longer boot and the power light comes on for a moment before turning on. I suspect either flash rom is not compatible with this chip or something about this chip prevents it from being read by flash rom. Using this guide: darajnish/dell5577medisable it seems as though a select few people have been able to set the hap bit by using the command soft-disable-only. Even when I try re-flashing the original read bios image however, the laptop still does not boot. I read somewhere that my chip has flash descriptors locked, but since other people have had success I'm not sure why I can't get it to work properly. Any advice would be much appreciated!
