[Tutorial] - Fixing a bricked system

[TheStranger]

I'll do it on more time and now i get an writing error:

Code:

dd: writing '/dev/system': No space left on device

My device is full  

Code:

Filesystem                Size      Used Available Use% Mounted on
tmpfs                    64.0K     64.0K         0 100% /dev
tmpfs                   256.0K         0    256.0K   0% /dev/shm
/dev/sdcarda8           185.0M    185.0M         0 100% /vp_mnt/Bundle
/dev/sdcardb1            29.3G     82.6M     29.2G   0% /media/sdcardb1
/dev/sdcarda6            26.4M     26.4M         0 100% /system

Is it a good idea to make "rm /system/*"
