That's not fully correct. It's just a bit harder. Just recovering the backup seems to result in many errors.

What i did to recover an old version is:

- wipe data, system and cache

- install zip of rom

- install magisk (because i had it rooted)

- restore from backup everything except system and vendor

- install latest gapps versions if you used gapps (Thats important, because installing an old version results in errors, because the data partition expects the new version)

if this doesnt work, than i would recommend to first recover everything and then dirty flash the rom zip, magisk and gapps, without wiping anythink (Except cache, that can always be wiped)

After that i could sucessfully downgrade to android 10, because i forgot to backups a handfull of apps

Did you resolve this issue?

I have the same problem, it seems to be related to the keystore, because apps, which don't encrypt based on fingerprint of faceunlock seems to work fine. Like CPL, Android Login and an App calles "Fingerprint test".

Apps that didn't work for me where a banking app calles "finanzblick", keepass2android, KeePassDX

I tried to gather some more Information regarding this issue:

Keepass2Android and KeePassDX have the Error "No biometric or device credential is enrolled"

During Registration of a new finger i get following error messages (Don't now why waiting finger has to be an error instead of verbose or debug)

Where ru.whatau.cpl is the CPL launcher

And a few Log Entries when i open KeePassDX as an example

I've made a clean install and used NikGapps-basic-arm64-11-20210130-signed.zip and installed Magisk 22.0 (Root only, no modules installed)

Other than the fingerprint issue this rom seems pretty good and stable so far. Especially the battery while phone is locked is back to a great level (First time that i didn't need to charge my phone over night). Thank you for that

i should have known that a few hours earlier :)

i managed to get most of my apps back out of the google account. then i had to go trough a lot of settings again to get the phone to be "mine" again.

Hi again

just a short update :

After I installed the ZIP files listed above I restored my applications and data using Titanium Backup.

Everything worked - including the Google PlayStore w/ microg and I can also use my apps bought in the Playstore with license checks via Playstore. Very cool.

The only thing that did not work was Push Notifications -- everything was green in the self check in mircog ; device registration and cloud messaging was enabled but Push notifications did not work in any app.

Today I found a website with instructions how to get the push notifications to work:

Issues with push notifications on the LineageOS MicroG version

I switched from 17.1 GSI with microG to Off17.1 with microG. Finally A2DP is working again. But I’ve got trouble with microG Cloud Messaging. No App connects to it. The push notification tester app leads to a red cross at “Register for Push Notifications”. Even the checkin dial (* # *...

forum.fairphone.com

Instructions form that thread:

"

After using these instructions push notifications now also work again.

There is only one missing step in the instructions:

After the last reboot you must grant all permissions for microg again in the self check for microg

Probably this hints will also help some other user

A BIG thanks to all that are doing a great job maintaning AospExtented!

Can you explain the next steps after installing this three packages?

What do i have to do after the first start?

What do i have to install for using microG?

What do i have to install and use, when i want using some apps as Signal e.g.?

Hylli
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] bnsmb:
Hi

well, these are not packages - the additional ZIP files must be installed via TWRP like the installation of the ZIP file with AospExtended. After all three ZIP files are installed you must first finish the configuration of microg : Use the app "microG Settings" that was installed with the NanoDroid ZIP file. In that app is a section called "microG Settings" that must be used to finish the config (If you need support to configure microG you should ask in a forum for microG.)

When this is done and microG is working you can use either the app F-Droid or the Google Play Store (both installed with the NanoDroid ZIP file) to install the apps you like.

Hi,

when i only install "NanoDroid-fdroid-23.1.2.20210117.zip", i don't have a microG App, where i can change the microG settings.

This is why i asked for further information.

Do i have to install further packages from https://downloads.nanolx.org/NanoDroid/Stable/ so i can install and use microG the right way?

Or do i only have to install some (which?) apps/packages from F-Droid, so i can use microG?

Hylli
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] bnsmb:
Hi

I recommend the Titanium App for this purpose -- the best backup app I know . And perfect for doing a backup before installing a new OS version. With Titanium you can create a zip file of your backups .That zip file can then be installed again after the installation of the new OS and you can then restore some or all of your apps including the data ( very handy if you delete the internal storage by accident as I did some times...)

Only drawback : Titanium needs root access and I strongly suggest to buy the full version

@bnsmb

Seems to work, after installation of both packages microG and F-Droid.

With F-Droid i updated Aurora store, so i can use the anonymous login for the store.

The only thing i do not understand:

How can i update the microG Services automatically?

Installed version is 0.2.17.204714, but Github lists a newer version 0.2.18.204714 from Mar 4, 2021?

F-Droid says, that there are only 4 Apps in this repo.

2. Is it possible that we don't have the same settings in microG? (I activated all in self test?)

I couldn't find the app in Auror Store, so i downloaded the APK with Raccoon, but the App doesn't work after manual installation.

It's such a pity, that the app doesn't work!

yes, did you sync the repo? The new version is not the one shown in the list. Just select MicroG Services Core and expand the section with the versions.

Hello,

I installed this rom, but I do not get any SMS...

I've checked the SMCS and it seems ok...

also the APN and seems ok...

Messages app from Google states : Failed to create conversation please try later ....

And the ROM message app will simple not move to write the message screen or anything.

Are other people seeing this ? (i've got 2 sims installed and happens with both)

[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] bnsmb:
Hi

Did you do a clean installation w/ wiping or a dirty installation w/o wiping?

Do you use some additional images like Magisk or microg?

I tried the new AospExtended-v8.1-z2_row-OFFICIAL-20210427-1926.zip today:

- dirty installation without wiping anything except Dalvik and Cache on the installed previous version with Magisk 22.0 and Nanodroid 23.1.2.20210117 installed did not work : There is an endless boot loop after the reboot

- the fresh installation after wiping system, data, cache, and dalvik works. But after the installation of Magisk 22.0 and Nanodroid 23.1.2.20210117 the ZUK is again in an endless loop after the reboot

Strangely enough, after installing the new image, the restore via TWRP no longer worked -- the restore aborted every time the system partition was restored, i.e. nothing worked and the LED was blue. The restore of the other partitions over TWRP went without problems.

I restored everything except the system partition with TWRP and then installed the previous image from AospExtended via TWRP.

Currently I use the previous version again.

There is now a new Magisk version available -I will test the upgrade with that version the next days

I did a dirty flash, but the first boot was a boot loop as well. So I rebooted into TWRP and reinstalled the update, including magisk 22 and nikgapps from April.

This time the boot worked, but the Google app crashed. I could fix this by uninstalling this app and reinstalling it via play store.

Now i don't have any exceptions and the only thing I realised is, that the vibration motor is now weaker, but for me that is completely okay. Didn't check if there's a setting for it

Without. At the end I had a working dirty flashed OS, just needed to install all 3 zips instead of only rom file. Didn't even wipe dalvik cache, even though this should never be a problem
[Lenovo Zuk Z2 Pro ROMs, Kernels, Recoveries, & Oth] bnsmb:
Hi

tried that -- did not work for me

After installing Magisk the next boot hangs. That happens independent from doing a wipe before installing the new AospExtended image.

Will continue testing

Update 02.05.2021

Found the problem:

The new AsopExtended works with Magisk.

The installation of Nanodroid version 23.1.2.20210117 (this is still the latest version) is the root cause of the endless loop (with and without Magisk). MicroG is mandatory for me so I will use the old version of AsopExteneded until I find a working replacement vor Nanodroid or a new, workingversion of Nanodroid

I´m still on Android 9, been using the same installation for way over a year, and I also have this ptoblem, in most videos but not all, and its recent, no more than 3 months, so I´m pretty sure the problem is App related, not OS.

About the update, any idea on how can I do a 'clean' install, also wiping storage? I´ve been accumulating files and kind of just 'updating' the OS since Android 7.1, but if I wipe data, will I have to upload the OS zip via ADB?

Also, should I update TWRP before? The app says the 3.5.2 is available, and I´m still on 3.2.3

yes

>>I´ve been accumulating files and kind of just 'updating' the OS since Android 7.1, but if I wipe data, will I

>>have to upload the OS zip via ADB?

no - it's not neccessary to wipe the data partition. Just upload the zip to /storage/emulated/0/Download/ for example.

>>Also, should I update TWRP before? The app says the 3.5.2 is available, and I´m still on 3.2.3

I recommend to update to the new version but I don't know if it's required -- you can boot from the new TWRP image without installing it to make sure it works:

#
# boot the device into the bootloader
# (the instructions are for a PC running Linux)

adb reboot bootloader

# now boot the device from a image local on the pc
#
# replace "/data/...maguro.img" with filenname for the TWPR image
#
sudo fastboot boot /data/backup/GalaxyNexus/recovery_images/recovery-clockwork-6.0.4.7-maguro.img
downloading 'boot.img'...
OKAY [ 0.993s]
booting...
OKAY [ 0.423s]

In v8.1 there seems to be an issue with the video recording storage path of the build-in camera app.

Pictures are fine, but videos are stored relative to the camera app "data" path in subdirectory "pictures", such that they are out of focus for gallery or filemanager apps.

Been using aosp for years.

Yesterday I decided to switch to this version.

Here's how it went (tldr: not good)

Fullly erased data/cache/system etc. Fresh start.

Installed the rom and nikgapps (openg goes only up to 10, if you know something I don't let me know)

Rebooted.

Installed magisk, copied the boot img, patched it, rebooted to twrp, flashed the patched image, rebooted to system, installed magisk manager, safetynet passes, etc. Restored my apps and data.

5 hours in the UI randomly rebooted and reset my system wide custom color and icon shape. Then it happened again.

I had a total of 5 UI random reboots since yesterday. Sometimes even when the phone is idling.

LTE data randomly disconnects and needs a full reboot to recover.

Sometimes the UI reboots are stuck animating forever.

Sequence:

1. Advanced wipe (dalvik, cache, data, system).

2. Flashed AEX 8.1, Magisk 22, NikGapps/Open Gapps, and (sometimes) baseband.

3. Reboot.

4. .............

Hey guys. I'm currently running on Pixy OS (10) after the updates for AEX stopped some time ago. Now with Android 11 I'd like to switch back, because there aren't any updates for Pixy.

I need your suggestion: Swith or Stay.

Right now my phone runs mostly smooth. If my battery is dead, the phone doesn't boot while charging but that's it. I pass safety net check and I got apps that usually detect root working (DKB, Blackberry work).

When I'm connected via Bluetooth my phone app is very slow and I can't pick up calls which is annoying. And there aren't any updates anymore.

Would AEX be an improvement or are there any issues that aren't solved yet.

Do you pass saftey net as well? Has anyone tried for instance the tan2go app by DKB?
