uninstall any system app will fail in boot error - OnePlus 6 Questions & Answers

up to Android version 9.0.8 it was no problem to uninstall system stock apps.
since 9.0.9 and now also 10.3 its not working any more.
even when i uninstall only one app e.g. google pay , the system will not boot on next restart.
i have only root via pached boot (Magisk Root without TWRP for OnePlus 6 Oxygen)
to get boot again i have to flash stock boot and install hole system via zip. (no data will be lost)
what security level recognize that some system apps are missing?

How are you uninstalling the system apps?

root and try again!

with app "system app uninstaller"
root and try again will be the same

how do you uninstall system apps?

try to use titanium backup next time
what kind of app u installed ? if its like stock from the rom itself, sometiems yes it will not boot up. and why did u uninstall it.. i mean its not that heavy.

There's ur first issue. Don't use an app dude. Either use the debloat Magisk module or do it through adb. Apps have a tendency to f*** up

in the versions before 9.0.8 it was not a problem to uninstall it.

It in android 10 you can delete apps permanently through twrp, these 3rd party apps not yet compatible to delete them even with root.

I tried using TB and no success. A pop-up was displayed in TB when I tried to unistall an stock app saying it was not possible (or so on, I don't remember the text). I did it in OOS 10.3.0.
In my experience, the only way to not see the apps is freezing them witn TB, for instance.

Problem after 8.1.0 update

Verizon Pixel Unlocked and rooted. I flashed the December release 8.1.0 (removed the -w). Everything worked as always, re rooted with Magisk. I had updates which include Data Transfer Tool, which has never shown up in the updates before. In the about information it says"This system app will be automatically installed on your phone. Please do not install this app." I can not find any way to stop it from trying to install, I cleared the play store cache, Did the January update, and it was right back. How do I get rid of it?
If it's a system app you can go into Settings/Apps and disable it or use a root tool to uninstall it like Titanium Backup. Just be careful, you might find your phone not working correctly if you uninstall it. At the most I'd disable (or freeze through Titanium Backup) first to see what happens. I don't even uninstall system apps anymore, I just disable them.

Installed Magisk on Pie but root and manager is missing

Hi All,
Having a strange issue with Magisk.
I performed the upgrade today coming from renovate ice (Magisk module).
I followed the instructions of flashing the full OTA of the pie update. And then the blusparks TWRP. I rebooted into recovery and then flashed Magisk 17.1 as per the guide.
Booting back into the OS I can see that Magisk Manager is missing and my rooted apps are unable to get root either. Also when I try to goto the themes section inside settings the settings app crashes on me.
I attempted to reinstall Magisk but this did not work. I only noticed that when I was running the uninstaller for Magisk it did detect my boot image is Magisk rooted despite the OS not reflecting this.
Any ideas? My next step is 17.2 but I have my doubts on it.
EDIT: I tried 17.2 beta release and it made no difference. Exact same symptoms

Manually download and install magisk manager app then try to open root apps.
Then give root permission that works

I was able to resolve the issue by performing a factory reset without having to wipe data. I'm guessing something old must have been left behind. Thanks for the help you provided, I appreciate it

Settings Force close

I installed a new version of the settings app (I'm assuming from the OnePlus 7) and now it only Force closes. Any suggestions on how to downgrade it? I can't access the app info. I'm not rooted and don't want to. I also can't access recovery because I guess my phone is encrypted and asking for a password but I never set it.
What did you download, from where? What OS? Substratum (this could be it if your themed)? Logs?
It's the OnePlus settings app from apkmirror. No root or mods or themes. Open Beta 18

The password for recovery is the PIN you have on your phone.

Hi,
I had the same issue as you but I was rooted and had TWRP. I tried to install OOS 9.0.5 again but it didn't worked...
So the last idea I had was to boot on the second partition.
And it worked.
You can try to boot on fastboot and type : "fastboot--setactive=_a" or "fastboot--setactive=_b" to switch partition and reboot. It should work for you too.
Oh that's a good idea. I ended up getting one of the app uninstaller apps from the play store and was able to uninstall the settings update.

Delete "Google Maps" stub

I've got my shiny new Pixel 4 XL up and running on the stock ROM after coming from a worn out Note 8. Everything is better except the new version of GMaps. I was using 9.47.x and this new 10.x.x is just awful. I want to completely delete the stub from the system so I can install the older version. I've tried several root uninstallers, even using the adb shell command. It always "uninstalls" but the stub is still there. Therefore the older APK refuses to install. I've even gone into the root/product/app/maps folder to try manually. It doesn't work, nor does changing any permissions. I have a feeling someone is going to tell me that this can't be done without installing a custom rom.
I'm guessing the culprit is not being able to remount the system with read/write permissions on newer versions of android. Unless there's something I'm missing.

It may be having a conflict with cached data from the version that you installed, removing the cached data might allow you to install the version you want.
Uninstall the app from system partition, then, power the device off, then, boot into recovery and wipe the cache partition, then reboot into system and try installing the older version.

That is right where the issue is. I can get it to the point from being a 66mb APK down to 200k where the system; or play store, even recognizes it's installed. I need to get write access to the system partition to get rid of the "Maps" folder persistently living in the root apps folder. If that can be done on 10 in stock recovery then I've never done that. Mind you I'm rooted on Magisk with the flashed boot image, no TWRP yet.

After flashing the Magisk patched boot.img, did you install the Magisk Manager app? Magisk Manager is what is used to grant root permissions to your other apps. There is more to it than just flashing the boot.img.
You can also use adb shell to remove the app as demonstrated in the second method described in the link below.

So I tried what you suggested, I got the same result. Maps uninstalls but still lives in the root directory. Not being an ADB expert I went into adb shell super user mode and tried the the rm command to delete the folder, also the remount system command. Neither of those worked. Trying to install the older APK results in "App not installed"
And yes I have Magisk manager. It installed the latest version automatically. I use RootExplorer and it has superuser permissions.
Would something like this work? I'm not completely clear on how this works.

Uninstall system apps

I am using OOS 10, which has TWRP and magisk installed. For some reason, i cannot uninstall system apps. I am trying to completely delete Chrome and other apks. I have tried going into TWRP, mounting system, and deleting folders and apks. I have tried root essentials. They all say it worked, but then the app still persists.
I do not want to disable, but completely remove, does someone know what I am doing wrong?
No idea what you're doing wrong but the xXx-nolimits magisk rom can debloat quite a bit.

I did the method in the link above then rebooted my phone once done with my adb commands and was finally able to get them off my phone
