Hello, I have a Xiaomi Note 8T (Ginko) with /e/ 1.8 (Android 10) and I want to upgrade to Android 11 /e/1.10.
To do this I need to do a manual update (I don’t see an automatic update in /e/ for this).
I have several questions:
Yes, that’s it
If uncomfortable with adb push, from a running Android you can also download from network or upload file from PC, any place will do!
As long as TWRP is able to access the zip file (that’s to say: you are able to access to content of /sdcard from TWRP), it really don’t care where the file is.
Note: with some devices TWRP can also work as MTP, making some phone storage accessible from a PC (better use Windows).
Hint: from adb shell, when in TWRP, you can use md5sum or sha256sum commands to check your file
The difference between a ROM file and a FIRMWARE file is: the content of course, but also the flashing script.
You can take a look a /META-INF/com/google/android/updater-script, inside both zip files.
As long as the /META-INF content is okay, TWRP is able to flash anything.
I would not advise to upgrade firmware with sideload.
Better download the zip file before (while in system), then boot to TWRP and use Install.
If you downloaded the file to the default folder, it may be in /sdcard/Downloads or something similar.
I’m not aware of /e/ Recovery flashing methods … Why don’t you stick with TWRP for now?
