OK, so I flashed /e/ onto my XA2 just over 2 years ago (Mar 2020). It was stock Sony Android 8.1.0 before flashing. It’s been fine with OTA updates up until last Dec, v0.20-o-20211210151039. No further updates have happened since then (yes, I have the phone set to auto check daily and any manual check says “No new updates found”).
So it seems it is past time to upgrade to a new base Android version, since OTA seems to be MIA now.
Side question: why?
I’ve watched the discussion here go around on which base version of Android to flash over for initial flashing. But my question is simply this: I already have a stable /e/ 0.20 over Oreo (8.1.0) installed. Given this, is it as simple as just choosing which new base Android I want to install (P, Q or R) and just going for it? Or – and I suspect this may well be the case – are there any traps for players who last flashed a phone over 2 years ago? If so, what are they?
The documentation was not very helpful back then (I even wrote in this forum that it was better to use the SailfishOS documentation for finding drivers for the XA2 to work on Windows, then switch to the LineageOS documentation to finish up). I am hoping the documentation has been revised and tested since. I also now run from a Linux laptop so finding Windows drivers is no longer an issue.
So that’s it. I’ve been running /e/ for 25 months on a Sony XA2 (4133, dual-SIM). But, as I use this phone as my daily driver (with two numbers, one in each SIM slot), I am understandably “trepidatious” about buggering it up. Anyone done this upgrade over an existing /e/ on an XA2? Did it hurt?
