[EDITED to correct TWRP version typo]
How does one upgrade an encrypted FP2 running FPOOS to 18.10.0?
So far as I understand, I need an upgraded TWRP; it appears that TWRP 3.2.1 (which I used to upgrade to 18.0.4) is insufficient because it fails a digest check on the .zip. However with either TWRP 3.2.2 or 3.2.3, whether I install them using the TWRP app or from TWRP itself, my FP2 hangs at the Fairphone logo when I reboot to recovery/TWRP with Vol+ pressed. After a reboot to FPOOS, the next reboot to TWRP finds me back at the default 3.0.2.
Anybody else experienced this?
Previously, my FP2 displayed an “upgrade available” message for a short while after 18.10 came out, but it then stopped. Even after I manually upgraded the Fairphone updater app to the latest version, it still didn’t detect an upgrade; however after manually downloading the new sibon .zip I found I could open that file using the updater: doing so only paused for a while, then rebooted me to TWRP.
