Thanks

Hi,

I personnaly had trouble to perform the upgrade, and ended up loosing all my data, see my post back then : community.e.foundation/t/samsung-galaxy-a5-2017-upgrade-to-r-failed-rollback-to-q-error/35117

Don’t know if it helps, but since R seems to be the last Android version that will come up for this device, it should be the last fresh install with data loss in the worst case scenario

Hi,
Thanks…and…so…
I successfully upgraded my phone from Q (e-1.8.1-q-20230206257879-dev-a5y17lte.zip) to R (e-1.19.1-r-20240110372392-dev-a5y17lte.zip WITHOUT losing my data

• To do this, I first made a backup of my phone with this tutorial :https://community.e.foundation/t/howto-backup-and-restore-data-on-android-devices/23292
• I have deactivated the unlock code on my screen.
• And with adb

adb reboot recovey

• On TWRP : Advanced → ADB Sideload
• On PC :

adb adb sideload e-1.19.1-r-20240110372392-dev-a5y17lte.zip

• then reboot system

I had a problem with the sound card at the beginning. I repeated the procedure to downgrade to e-1.17-r-20231111351093-dev-a5y17lte.zip, reboot system and upgrade again to e-1.19.1-r-20240110372392-dev-a5y17lte.zip. The sound problem has been corrected as below.

Good luck to you
