So we see channel predicted in [LIST] Devices which will be getting upgraded to /e/OS T but I guess the ROM and e-recovery are not yet published. Furthermore e-recovery are a little “behind” in general Week 39, 2023: Development and Testing Updates - #28 by Manoj.
The Upgrade page tells us to
Run
adb sideload /path/to/zip(inserting the path to your /e/OS package).
where /e/OS package would be a matching pair of e-1.nn-X-xxxxxx-dev-channel.zip + recovery-e-1.nn-X-xxxxxx-dev-channel.img.
So today I would think it ok
-
for Android 12 (S):
e-1.15-s-20230916331435-dev-channel.zip + recovery-e-1.14-s-20230818321663-dev-channel.img -
or for Android 13 (T) … wait for a matching pair.
