[GUIDE] How to unbrick a totally dead MBL

tried at least twenty times fat32, fat, ntfs usb drive and sd card yet i always get the unable to mount after i enter

mount -t vfat /dev/sdb1 /mnt/usb

and the sdb1 does correspond to the proper drive with all the proper files intact on it.

i was totally able to get all the files off of it as it was still visible with the programs sugessted in the howto,

cannot seem to get anything started though as i can’t mount it.

any ideas anyone?
