[Tutorial] - Fixing a bricked system

[TheStranger]

No not worked - get same errors.
I compare the both signature-files and they have the following data:

Code:

2015-03-12 17:20:11
dev
vicsiu

But in the bootup they get a warning with another datetime:

Code:

2015-12-17 16:26:59
dev
vicsiu

I think they dont flash it.

I do this with my originally firmware-backup:

Code:

1. format the SD as FAT32
2. copy my backup.bin to SD
3. starts putty and connect
4. check if SD is mount (ls /media/scardb1)
5. Flash
if=/media/sdcardb1/sdcarda6_backup.bin of=/dev/sdcarda6

Can i clear or format the old sdcarda6?

Another Question is - i'll do it all in windows putty - must i'll do it in linux too?
