thanks a lot!!
Now, if I understand correctly:
I have to flash the device with my own recently done ftf
(or by using SE Companion)
then I have to re-root it with flashtool,
and then, booting in xrecovery,
I can restore my rom from the backup I made
and I get the system correctly configured again ?
So, if I'm not wrong, xrecovery backup is not a full rom backup image.
Will Nandroid do a full rom backup image
allowing for a one-step rom restore between CM6 and previously made SE backupped ones?
Many thanks in advance
