Take the attached file and flash it using the program you used before: fpt -me -f 7H3_0122_ME.bin
That is the stock firmware extracted from latest bios, picture to the right.
Please post result as screendump of flash window/ picture. Don't continue if you get error messages as in your last try, take screenshot/ picture, post again!
Check the ME after this flash with MEInfo -verbose and MEInfo -fwsts (If I remember right the results of the 2 commands are different for ME 6). Please post the 2 results.
Regarding udate to latest version- these are the different files SP 81826 update preproduction, SP 80262 same version but 'rev A', update production, file from repo in Win-Raid update, ME region og latest bios, ME- region!
If MEInfo result was OK you might update the ME FW to the latest version using the FWUpdLcl command and an update firmware from the repository (ME 6 Desktop 5MB v6.2.61.3535) FWUpdLcl 6.2.61.3535_5MB_DT_PRD_UPD.bin -generic
Check the ME again: MEInfo -verbose and MEInfo -fwsts
(I’d avoid the pre- production FW from HP since these firmwares normally only work with pre- production hardware)
