I have written about this quite a lot through the forums, but basically all you are doing is to copy off and back on your internal SD (everything), with TiB backing up my critical apps, and SMS Backup for TXT/MMS, then I wipe the device, install fresh, then restore on top of the new OS and never lose a thing. I have TXTs from 2015 still on my device, from SMS Backup through multiple devices and OS's, same with my data. Once I copy it off/on, I don't lose a thing.Mind making some more detailed directions? I'm coming from version 11 of android (enjoyed the stability) and trying not to lose stuff in the update process.
Let me know what you get stuck on but don't expect to move from Android 11 to 13 with OTA or dirty flashes. You should CLEAN flash it or you risk a lot of headaches. What ROM are you on that's running A11 but wish to upgrade to A13? If its a ROM like LOS, you might be able to OTA update to 13, but again, I would only clean flash. Don't take shortcuts.
