I just bought a zte android n762 last month. Now it has stopped start up or booting to the oper sys. I have changed the battery, tried several different chargers, changed the SD card, and went to the basic retail shop to ask for trouble shooting advice to retrieve my data? No help all they say we will replace the old device to new one. Come on please there has to be a way to get my old data back?? Any help appreciated. Folders in android are :- dcim/notepad/documents/several apps folders automatically installed.
