S9+: Unable to update to eos1.4 due to TWRP will not Decrypt Data

aibd · October 13, 2022, 8:52pm

This should happen if you go to Settings > System updates > top right 3 dot menu > Preferences > Update recovery.

The position of this toggle changes with Android version.

When update recovery is selected, we expect TWRP to be replaced by the /e/ Recovery to match the /e/ version being installed as the /e/ OS update happens.

If you originally used Easy Installer, you are likely to be on a stable build (reference: https://doc.e.foundation/build-status). You should avoid lightly changing from Stable to dev channel (or vice versa).

On Android 10, this can be confirmed from

Settings > About phone > Android version > /e/ OS version – Long press on /e/ OS version to copy to clipboard.

Thanks for the suggestion. I have replaced TWRP with e.14 recovery already. Now I am hoping someone can help me install Magisk without TWRP if that is possible for S9+.

.

Why not install TWRP after each /e/ update to flash the patched-boot and then replace it by recovery-e before each /e/ update ?

OR simply keep TWRP and just “dirty flash” latest e-build over the precedant instead of perform OTA update ?

which TWRP version do you recommend that does not have data decryption issues with the S9+?

piero · October 13, 2022, 10:02pm

Maybe None,
it is the reason why it was (provisoiry ?) abandonned.

sfeos · October 13, 2022, 10:05pm

can I still use twrp (even though it does not decrypt data) with s9+ to install Magisk or another recovery like Shrp?

piero · October 13, 2022, 10:08pm

Yes, you have already did it in the past, before opening this topic… no ?

Only actual Problem with TWRP is OTA update using the system updater, because it will store the file under “/data/lineageos_updates” and TWRP can’t uncrypt “/data”
No problem if you download the latest /e/.zip file and flash it using the “sideload way”.

sfeos · October 13, 2022, 10:14pm

that’s true. I did have twrp (that did not decrypt) that also installed Magisk but when I installed e1.4 os it wiped Magisk and twrp off. I was just wondering if there was an easier way to install Magisk without TWRP but I guess you are implying there is not an easier way. If there are future eos updates, do I reinstall TWRP again in order to get Magisk every time?

Thanks. How do you do a dirty flash?

piero · October 13, 2022, 10:24pm

Download the latest /e/.zip file, reboot into TWRP, tap to install, navigate to the downloaded /e/.zip file …
WITHOUT WIPING ANYTHING is a dirty-flash

If it don’t work because “/data” can’t be uncrypted, use the “sideload method”

sfeos · October 13, 2022, 10:26pm

when I did that last time to install e1.4 to update, it automatically replaced TWRP with e1.4 recovery. Did I do something wrong? I don’t think I wipe anything.

Not If you unselect this feature.

sfeos · October 13, 2022, 10:31pm

Under Settings, System updates, there is
Auto updates check (never, once a day, once a week, once a month)
Delete updates when installed
Mobile data warning

I do not see Update recovery.

sfeos · October 13, 2022, 10:34pm

I do not have the Update Recovery feature

piero · October 13, 2022, 10:45pm

As @aibd often advise, “sleep on it”…
And Re-read the entire thread

Perhaps it is because you are on stable build, perhaps it is because recovery-e is actually installed …

sfeos · October 13, 2022, 10:47pm

Thanks for the help. I appreciate it.

In an earlier version the Update Recovery feature was at Settings > System > Developer options > Update recovery, see also Cannot boot into TWRP after upgrade to v1.0 - #8 by aibd

I want to thank everyone here for being so patient and helpful with my inquiries. With all your help, I was able to accomplish the following:

Update to e1.4 from e1.2
Install Magisk via TWRP

It was quite the interesting experience and I appreciate everyone’s help and kindness. I wish all of you well. I look forward to future improvements to make eos even more seamless to install, update, and include easier optional rooting features for beginners like myself.
