I explain better:
I made a full nandroid backup & a full titanium backup on my old PB G100W, then I received a brand new tablet from Acer.. Now I would restore back all my apps & data, so I made downgrade from HC 3.2.1 to HC 3.0.1 unstable, root, recovery 1.3.4, updated recovery to 1.7.3 touch and flashed Tegraowners v169.
I restored apps by Titanium and everything was ok, but 2 apps (Opera and a game weren't work properly). Tried something to solve it, but nothing.
I decided to restore my last nandroid backup from cwm 1.7.3, but nothing, restoring boot ok, restoring system ok, restoring data works for a while, almost at the end stops and give me back "Error while restoring /data!".
Maybe my backup could be corrupted or maybe it's a internal storage issue.
So I made a real format (data/media enabled) -> /format system.
Retried, nothing, get back the same error.
Flashed back recovery 1.3.4 by thor and retried restoring, works for a while, then stops again.
I tried another nandroid backup, different from the first one (of 1 week before), same procedure, and stops and the same point.
So, I got two corrupted backup or I'm missing something?
I tried so much methods that I bricked the tab, but solved with TimmyDean's method, unbricked, reflashed and then (I don't know how) all Titanium backup were working and no issues.
Maybe the solution on titanium back is reboot a few times.
