Not working on Dell Inspiron 5570 #293

Hello

unfortunately I didn't succeed on my laptop Dell Inspiron 5570, cpu i5-8250u (the same cpu works on others laptop without intel ME).

In the eeprom I read that the code starts with AH1819 and I can't find any information about that in the web. Flashrom detect a Gigabyte eeprom and suggests me to use the option '-c "GD25B128B/GD25Q128B"' or the option '-c "GD25Q128C"'.

I made the first backup with the option '-c "GD25B128B/GD25Q128B"' and if I restore It, after a few tries, the pc works correctly,

If I try to write a me-cleaned image, with every possible me_cleaner option, the pc doesn't boot. I see a led on, then the fan turns on and nothing more happens.

I tried to remove the batteries, the hard disk, the ram, and pressing the power button in order to reset the BIOS, but in every case the laptop doesn't boot.

I assume that me_cleaner doesn't works on this board.

Thank you

I've seen dell implementations with Two ME regions. They were both in the same EEPROM, with two partitions. came up as same chip numbers just with a different ending. The EEPROM had double the memory it usually needs. If there is a check going on, you may have to see if you can find a second image on the board and flash both to be matching.

Good luck if you try again.
