I have a OnePlus One running CM13. Recently, I got into a boot loop and had to go to a backup I had made in TWRP v2.8.7.0, but after I did this, the SIM card was not detected. My friend told me this was a bug in versions 8.6.1 and later, and said I should flash 8.6.0, then go back to that backup. This made TWRP accessible, so I tried a factory reset. My phone rebooted and nothing happened. So I installed cyanogen recovery instead and reinstalled CM, but that didn’t fix anything. I tried to flash TWRP again, and now neither recovery is accessible.
Now I have an extremely buggy CM that reboots automatically every 2 minutes with no recovery mode and my SIM isn’t detected. I’m considering installing Ubuntu Phone or buying a Nexus, but what I really want is to install TWRP, get my SIM detected, and install CM13 release track.
What in the world should I do?
