I played a bit with my Android-Device, partitioning my SD-Card to met the requirements of Link2SD (without success).
Finally I formated the card and copied the data back onto that card, so it looks like before.
But since then I cannot access the Internet any more. When trying to activate Data my Galaxy Tab 7.7 keeps telling me I do have to enter a sim card.
Is there any chance to solve that problem without wiping?
I have Titanium Backup installed, so I might be able to restore some data if anyone could tell me what to restore.
