As a family mobile tel maintainer my feeback is:
1
Google
Pixel 5
redfin
e-1-19.1-T-stable
not rooted
upgrade to e-1.20-t-stable locked at “reboot preparation” at 50% during 40mn. So I cancel upgrade.
Need to investigate why…
2
Lenovo
Yoga Tab 3 Plus Wi-Fi
YTX703F
e-1-19.1-R-dev
rooted
upgrade to e-1.20-R-dev : no issue evrything OK.
3
Xiaomi
MI10T
Appolon
e-1-19-1-S-dev
rooted
upgrade to e-1-20-T-dev not available from “param/system upgrade” so I upgrade the device manually (fastboot flash recovery and adb sideload). Upgrade works finely, no issue.
