[Q] secure erase of /data, remove cwm
Hey there. I have to send my Tipo in for a repair. Afaik, warrenty is void, if no stock rom is used.
questions now are:
how can I securely delete the phone, especially /data?
with CM 10/Android 4.1, internal memory is not available as USB mass storage device and therby cannot be deleted via a PC afaik
how do I restore stock rom? more precisely, I have a backup of the stock rom, but this contains cwm. this should be removed obviously?!
