So, I flashed that dual sim firmware on my ss xperia m. Everything worked fine, and I tried to root with that cydia impactor method. Everything seemed to go well, until rootfixer step. So I run rootfixer, it seems to be going well, but after the reboot, when it tests did it worked, my phone reboots(so I guess it failed to full root). I get Error: Device not found in cmd, and that's about it. I tried it several times, but I did not managed to get full root with this method. So, are there any other methods to get full root on 4.2.2. ss?
