e-OS S is available since a couple of months for MI 10T. Has, someone, successfully install it ?
My goal is to upgrade from R to S without data loss!
I try but I don’t success
Upgrade doc explains phone must be on the same Android release.
I upload the last Xiaomi ROM (V13.0.2.0.SJDEUXM which is Android12 based
I try to flash it but:
- e-os recovery says the signature is not well suited
- I bypass that issue by answering yes to the question “flash anyway?”
- at the end of the game sideload abort because dates are not valid (Xiaomi Rom is older than the current ROM (e-1.2-r-20220727)
- I try to replace the e-os recovery by TWRP but unfortunately there is no Apollon TWRP release
Thanks for your help @smu44 .
My initial idea was to flash only the firmware, but I don’t find a detailed howto for Apollon.
So as an alternative, I read on LOS forum, than it is possible to flash the full ROM, using the recovery and then (taking care to never boot on system) flash the new recovery (using fastboot) and then the new S system release.
That way to do seems to avoid dataloss
But, thanks to your advices, I have a quick look in the install script, and I just discover than the date issue is part of the installer script (I know sometimes I’m stupid)
So I edit the script, suppress the date check, and put back the new script in the zip file.
I will try that asap, but I have to make backups carefully (in case of dataloss), because it’s the daily device of my wife and I want to avoid divorce .
Another time, @smu44, thanks a lot for your advices and a happy new year.
