Work smoothly for 3 months.
Everything working fine
But i didn't find any option for turning on flash in camera and also no shutter sound selection option .
I tried the other gallery/camera app but F.C And same problem.
well, as i see you use Flashtool and select the Fastboot mode to flash...once you selected Fastboot mode it pops up another window called Fastboot Toolbox, right?
There you hit Reboot into fastboot mode (via ADB) the button located on left side ...
