Thank you @NeoArian for your awesome work!
Just a question: now that 18.1 is out, will there be any more builds for 17.1 (e.g. security patches)? I'm asking because I'm going to wait some time before doing the move to 18.1.

Hi,

Very Thank you for your work

With the 17.1, I initially used Magisk 20.4. It was OK.

With the 18.1, I'm trying to install Magisk 23.0, but for now it's KO with me (I'm android newbie ):
- Magisk-23.0.zip install with TWRP: OK
- Magisk-23.0.apk install: OK
- but Magisk app tell me that Magisk is not installed
- I try to patch boot img..., same
Some tips for Magisk and z3c / android 11?

Best regards

This worked for me

Thanks Klbgr, I modified assets/boot_patch.sh in Magisk-v23.0.zip, it works for me too.

No, there won't be further updates of lineage-17.1.

Upgrade from LineageOS 17.1
Please follow the instructions here.

So what exactly should still be wiped (case/dalvik/system)?

You don't need to wipe anything. However it won't harm and you won't loose anything of you wipe cache and system before upgrading.

 

[marcypan]

Thank you for your awesome work!

I made a clean install (been using unofficial 18.1 build previously) with Nano GAPPS pack and everything works perfect for now. I even tested Google Pay and purchase was successful! I wasn't expecting that!

 

[L.Lmar]

I have tried upgrading from 17.1 without wiping data without success. Loading reached the wallpaper, then boot animation started again

Everything is looking good except I can't unlock the screen for some reason. I use my old pattern but instead of unlocking it throws me right back to the unlock screen again. Any ideas?

In this case you should wipe data. There might be issues if you have used a pattern. I have tested an upgrade from 17.1 to 18.1 without a pattern/pin set.
The reason for this is that support for the legacy credential hash support was deprecated and we had to remove the legacy hardware keystore.
If you want to keep your data, you could try to remove the pattern on 17.1 and do the upgrade, but i can't guarantee that it will work.
Sorry for the misleading comment in the OP.

Thanks for the clarification. All good now.

 

[t.Lancer]

Just wanted to give my thanks for supporting this phone. Although I have moved to the XZ2c. the Z3c still acts as my backup.

thanks again!

 

[Samare]

Thanks again NeoArian for supporting the Z3 Compact!
I've installed LineageOS 18.1 and everything is fine except...
a kernel wakelock: sensor_SMD 2000000000
Because of that, deep sleep isn't what it should be.

It seems that the Z3 Compact isn't the only phone with that problem: msm8937-common: Disable the Significant Motion Detector

 

[Samare]

CPU-Z doesn't show any data for the Significant Motion Detector so it seems like a no brainer to disable it at least for now:

 

[Samare]

I've changed my build.prop

ro.qti.sensors.smd=true

to

ro.qti.sensors.smd=false

-> problem solved.

By the way, I checked an old build.prop from LineageOS 17.1 and it used to be disabled, which explains why this problem is linked to 18.1.

Is there a reason why GPS doesn't work for any App / Tracker while Screen is turned off?

I tried the update without wiping anything - it ended in a boot loop.
Any change for upgrading without wiping data partition?

I did a short test with FitoTrack without any problem. I'm guessing you made sure to enable the location permission in always mode?

Same here.
You can either try the integrated Seedvault backup (enable the backup apps option) or use the Migrate (requires root) or OAndBackupX (not tried) app.
