“* For a clean installation (It will erase everything, factory reset)– Remove the battery to the L7 and while holding the key Vol+ connect the USB to the PC ”
and it didn’t erase previous version of Android. My phone is only upgraded. I wanted clean new software, cuz my previous ICS was sim locked. Now i have JB 4.1.2 and it’s also sim locked. Any advice how to do it (to completely delete my phone and install fresh version and automatically unlock the phone)? Thanks in advance.
