My device is f240s i flashed e988.kdz when i flashed that my internal storage became 16gb. (from 23gb to 10gb) then i lost my imei and no signal. after that i reflash the f240l stockrom , flash my efs backup then i got my signal back. But my internal storage is still 16gb. Tried factory reset but 16gb remains. Gonna try reflash all over again later
