My Sony PRS-T1 (Android 2.2) is not behaving as it should. In spite of numerous attempts to flash the restore set and sd rescue, I keep having problems with the dictionary change operation, with annotations, sometimes with the browser hanging while loading a page I have loaded many times before.
I had rooted my Reader for a time but at the moment it is back to the non-rooted state.
I suspect that either the partition table is corrupt or there is malware "somewhere deep".
How could I check the integrity of the Android partition table and, if necessary, repair them? I might root it if need be.
