          Yeah, i am currently having the same problem. I rooted my mega and my gallery, wifi and everything on the device storage were locked. It’s there but its not visible. I’ve tried unrooting it but to no avail. Havent tried ur methods yet, but i’ll comment when i do. Thank you!

            This method flashes the stock firmware on your device. It removes any custom ROMs, or any other kind of modifications on your device, and gives you a phone that’ll work like you’ve just bought it off a store.
