No, i haven't made backup but my computer has restarted perfectly. My Bios
version hasn't changed and i have profited this time to make the backup. I
have attached at this mail the "recovery.log".
Thank in advance
Flashrom should also have told you if you are safe or
not (to reboot).
So I presume you did not include everything flashrom printed.
Nevertheless it looks like flashrom modified the content of the flash
memory and that makes it potentially unsafe to reboot.
To recover I would first try to write the backup you read before with
flashrom -r ... you did make a backup, didnt you?
Please send us the complete log file created, e.g. "recovery.log" when
flashrom -p internal -o recovery.log -w "backup.img"
