if you don’t want to wait for the “Over The Air” upgrade,
(backup your things first, in case…)
in theory, from e-2.9-t- you can :
- download the file https://ota.ecloud.global/official/FP5/e-3.0.1-a14-20250607498722-official-FP5.zip onto your smartphone, and use the “local update” function in
→ settings → system update → 3-dot menu at top right
or
- start your smartphone in recovery mode, select “Apply Update From ADB”, download the https://ota.ecloud.global/official/FP5/e-3.0.1-a14-20250607498722-official-FP5.zip 2 file to your PC, and run the command
adb sideload e-3.0.1-a14-20250607498722-official-FP5.zip
