Member: 2849478 Status: Offline Thanks Meter: 1 | Well I flashed the phone with update_full_base firmware downloaded from the net. Now it starts and displays "Your device has loaded a different operating system." and restarts in eRecovery mode. Where I can download software for this phone? Is there any in support area? |

Member: 2891705 Status: Online Thanks Meter: 2,141 | You can try to re-flash device firstly with board firmware via Factory mode, then re-flash device with same stock firmware version via Fastboot mode. Thereafter, send us result. |
