Why did you unlock it as V3x if you have the option of E1070?
The camera problem should be related to flex, don't rely on flashes from boot-loader as they have only few languages avaliable. The best way is RSD Lite, you can find flashes for it easily.
If you have more than 1 phone, and easy way to repair is to make a backup from a working one and flash it to the faulty one, after that restore security area. |
