    That means your data partition is probably messed up. What where you doing before this issue occurred?

    Last week i updated to COS13 but had troubles, couldn't call or receive/send sms, because i couldn't find a solution i did a downgrade again to cos12.1.1 . Had a factory reset and reconfigured everything without any problems. But i'm facing a problem that a never had before in the past.

    My mobile network is constantly switch from 3g to 3g+ (every couple of seconds it switches) or loses signal, where in the past there was never a problem, always stable connection. If I switch off wifi it can take 5minutes till i've got mobile network.

    I removed my APN and add it again. Switched to 4g, 3g etc. Nothing seems to help.

    Someone has idea how to solve this issue? It's really unusable this way.

    Thank you.

    i dont know how it started but i think it got updated then all this started, but i kept trying some basic things like connect it to laptop and charge, then i have done "power button+vol up/down" keys many times, sometimes it get starts and run properly and then again goes to same loop, so finally once when it was working fine i did factory reset, but after that also it went into same loop once or twice....ryt now its running properly but donno till when it will run...but you please tell me what to do when it happens again...

    @Reboot101 I have wifi issue on cos 12.1.. U have placed a link of a file that can be flashed to fix it. Also, the mobile network signal isnt good. So there's a fix for that too. These issues require flash. Can i flash it using stock recovery? Or do i need to have a custom recovery? My opo is complete stock n i have no intention to unlock bootloader and install custom recovery. Please help

    For those of you who have a glitchy phone due to the updates, all you have to do is Restore/Factory Reset (for some, you have to wipe cache, etc) your phone like you would do on a computer (in the BIOS of the phone). I did this yesterday with CM13 and my phone became anew, with the same version of the OS. I realized I was an idiot. If you're reluctant on losing saved photos and other stuff, I wouldn't know another way.
