Brikk and backup nor

Hello guys.
do you think it is possible that the backup with ps3xploit flash dumper is corrupt?
I brikked the ps3 because during the flash of the memory there was no current and brought me the ps3 of brick.
I already had a few seconds before the backup.
I have e3 flasher and then I decide to restore the backup offered before the brick but it is corrupt and the ps3 shows no signs of life.
black screen.
Could it be that the backup performed via ps3xploit flash dumper is corrupt?

Thanks
