While Trying Lenovo's A50 system.Img ... everythig went smooth and fine and superfast ... untill the time i realized that the soft keys have changed their way of function ... they blink but not work as they were supposed to work on A75.
Things i tried to solve ... but no success :
Rebooted : booted well and fine, just soft keys are dumbed.
Restored different backups .... no use, but the screen got unresponsive or misresponsive.
Flashed different ROM's ... no success ... the issue persists.
Power+VolumeDown ... Tried to calibrate the device but got stuck at Keys Calibration. Instead, additional camera keys appears in lieu of a75 soft keys.
Frilled myself and formatted phone completely including the format of NVRAM and NAND successfully.
Flashed Phone with Stock ROM. Ran It with no issues .... but the soft key problem persists.
Any Last day HELP, Advise, Suggestion, To-Do's-n Dont's... before i head to the Service Center ...!!!! ... Will be highly appreciated.
Thanks In Advance ...
