[Tutorial] - Fixing a bricked system

[Greg677]

Hello,

My storio3 can't boot correctly (black screen after storio logo), the sdcarda7 seem corrupted (squashfs error, unable to read some files from /system/).

I'm flashing it with 3_FR_v39.30916-MOD.bin (dd if of) and now the system boot but the main screen is locked to official message "Update fail..... ect"

I'm connected to the busybox of the storio3 and i'm find several errors (see below).

!!!kernel.bin does not match to system.bin!!!
