I installed avast! Mobile security on my rooted Galaxy SL.
In the anti-theft setup I chose the Write direct option and the phone went into a boot loop.
Had to restore from Nandroid backup.
Would welcome any advice or assistance.
Thanks in advance.
Restored system and retried setup.
Phone no longer loops.
But I receive a message about being unable to write to system because of lack of space and then phone reboots.
Tried the Recovery Image method.
Received:-
E:Error in /emmc/UPDATE.zip
(Status 0)
Installation aborted.
Found the answer.
Now need to resize system partition or delete some files.
How do I mark this solved??
You don’t, but I’m glad it’s working
