When my Motorola G32, which I really liked, died in a very strange way, I got the Redmi Note 9 Pro as a replacement from my friend Tom.

It came with LineageOS 21 already installed, which was fine. Today the update to LOS22 (Android 15) arrived, I was a bit nervous about the data and the backup. And here it is... article about how it went... Here is the screen of the freshly updated phone.



So when I got the announcement of the new main release, I was just afraid to back up all my data, because I am still used to the idea that upgrading the custom ROM means wiping the data and rebooting to a clean phone. However, after reading some more info, those days are back! And I am really happy.

To lower expectations, I still had to use my phone to upgrade to the higher version. However, it was really easy and it was just two/three commands and it was done.

So all I had to do was download the latest build and new GApps to be safe, restart the phone from ADB, sideload the new lineage, sideload the gapps and wait for the miracle.



And... everything is perfect. When the phone booted up, I saw my wallpaper and saw that I had won. Everything was where it should be and working. But... the fingerprint sensor was dead... I was confused and thought that this build had some problem detecting it. Fortunately, after some time I realised that the fingerprints are stored in a special encrypted memory, so it might have been erased when the ROM was flashed, and I was right. So the sensor was dead just because it has no stored fingerprints, so it has nothing to compare.

So I just added the fingerprints again and everything works now. So I am really happy and now I am just waiting for the easy update to Android 16 next year.
