I'm trying to convert an app to a system app by placing it in /system/system/priv-app. I'm rooted using Magisk, but otherwise running completely stock Pie, with stock recovery installed. Here's what I've tried:
1. Using Magisk's Terminal App Systemizer module. This was the first approach I tried.
2. Using ES File Explorer to move the folder and change permissions.
3. Using Link2SD to make app into a system app.
4. Booting into TWRP using Fastboot, then using TWRP's File Manager to move the app into the /priv-app folder and set permissions.
5. Following the directions here to place the .apk directly into the root of the priv-app folder.
6. Following the directions here to make a folder for the app inside of /priv-app through adb shell and placing the .apk inside that folder.
Each time I've done this, when I try and reboot my phone it hangs during the boot sequence on the G logo with a little loading bar at the bottom. After a little while, the phone will automatically reboot into recovery and prompt me to either do a factory reset or try again (trying again causes a bootloop). I can boot back into the bootloader using the hardware keys and use fastboot to get TWRP running. From there, if I delete the .apk inside the /priv-app folder my phone will boot as normal. Note that I've had to sideload the OTA image when I used Magisk/Link2SD to systemize the app, as I couldn't find the app inside the /priv-app folder at all.
I've tried 2 different APKs with the same result. I make sure to set the proper permissions before rebooting, but it would appear that I'm doing something wrong with the .apk, since the problem goes away as soon as I delete it from the /priv-app folder.
Any help? What am I doing wrong?

Hey guys,
I still rename my bloat, I know, you probably see this as lame, but maybe someone has the answer anyway.
In system/app, the Motorola Migrate apk (fswriter.apk) can be renamed using root and Root Explorer, but after a minute or so, or a reboot, the apk returns to the original name (I usually add .old to the end). Just about all of the other apks I rename in that folder retain .old in the name even after a reboot. The entire contents of system/vendor/app does this. I can rename the apks, refresh and see they are still renamed, and then a minute later, or a reboot later, they drop the .old or .delete extension.
For now, I disabled the ones that appear in the app drawer, but maybe someone who is curious enough knows the answer.
Thanks,
Jason

are you rebooting into R/W mode aka recovery mode? For this line of Droids, after rooting, in order for you remove or change anything within the system you need to reboot into "recovery" and i use the quotations is because in all androids in the past (at least the ones i have had) recovery is TWRP or CWM but with our phones recovery is the OS but the OS is R/W...so make sure you are rooted and then you can either use an app like Rom Toolbox for example, use the rebooter option within and in that menu select Reboot Recovery, it'll reboot into the OS but rewritable once you are booted that way you can add and remove system apps as well as make any name changes to the system files and whatnot...hope this helps
Holo reboot in play store works great for rebooting into recovery or just a normal reboot!

I downloaded a music file (using U torrent for android) to the Internal Storage/download folder. I tried to delete it but it is grayed out and unable to do so. how can I delete that folder and it's contents? Thanks in advance.
Might the file still be "in use" by the uTorrent application? Try fully stopping the torrent file and deleting it from within the app if it has the option.
Ran into a similar problem. If the above doesn't work you will need to delete the file without booting into the OS.
Options:
1. Reboot and try to delete the folder again.
2. Custom recovery with file manager and delete from there.
3. Boot into bootloader and use adb to delete the file.
All of these options can be learned courtesy of Google.

Some apps (such as Huawei Health) are installed on your device during the initial boot. They can, however, be uninstalled, and there's no obvious way to get them back.
Here's how you do it!
The APKs live in the /cust directory on your device. You can either pull them (using ADB, e.g. 'adb pull /cust/preinstalled/public/app/') or use a file explorer app to browse to the same directory and click the APK you want to install.

I tried installing it with both Flashify and Magisk, but both methods failed.
When I tried installing it via the included Xposed Installer, it also failed, but gave me the message:
> Error: Xposed_Framework.jar already exists in /system/framework
I'm guessing a previous installation failed, but left the file there.
My next idea is to delete that file from /system/framework and try again, but since it's in an RO directory I don't have permission.
I tried using a terminal emulator to mount the drive in rw mode, and also tried using a root file explorer, but either both methods don't work, or I just couldn't figure it out.
Anyone have an idea of how to remove or rename that file so I can try to install the .zip ?
-Thanks

In the Xposed app you should be able to just run the uninstaller script. If that doesn't work, boot TRWP and delete it from there.

Unfortunately, the uninstaller also fails.
It says it can't remove that file from a read only directory..

Root Explorer....
This app does wonders, it allows you to modify directories in /system and other root folders. You can even change permissions of specific folders/files from read/write/read-only....etc. I've had this app since the earliest of android days and it has been my go to file explorer. Root Explorer of course requires root....but it completely unlocks your phone and allows you to modify any system file that is set to any permission. Of course there are other file explorers that allow you to modify system files, but this is the one that i have the most experience with. You should be able to access the system folder where the Xposed file remains and modify it so it can fix your problem.

This!. I've used it for years. Not muss no fuss. It's not bloated like a certain couple others I know of. It just does what it does and does it well. Manages files. No extra garbage.Give it a try. I'd be surprised if you can't delete it with Root Explorer. If you do try it, go to the folder you want to delete the file from. Once in there, look at the top right of the screen. Somewhere up there It will say MOUNT R/W. Touch that and you should be able to do whatever you want to within that folder.
Do you have the magisk DNSCrypt module installed? If so, thats why you cant modify anything in /system. Not sure why or how it breaks it, but it does. Took me for ever to figure out what was causing it. Now that i removed the module, i can modify anything i want again.

A reference to ware the file system in oxygen lays for apps.
User app= /data/app (the folders for each user app are not labeled after what they are.)
System apps (in OxygenOS))=/system/product/priv-app or /system/product/app
It depends which type of system app you intend to make to app. Either directory works.
So I like viper4android and will use it as an example.
1 download this version ViPER4Android-FX_2_7_1_0.apk
2: install it as a user app. It should work now but need the rootless driver install in twrp for it 1st.
3: boot 2 twrp, mount all partitions (works better). Flash the zip, reboot to system.
4: verify the app functions add the Ulta low buffer module or what ever else need to be hooked to the app were Systemizing.
5: everything set use a app like Sdmaid to get the actual directory name that oxygenOS installed it to. Just the 1st two letters works for this to ID it in twrp (ware we won't be able to check.
6: boot to twrp. Mount all partitions. open a file manager it has. Go-to the app's directory under /data/app/... That apps directory. Open that directory and move the next directory to...
/System/product/priv-app or /app.
7: you don't have to but you can now use the file manager in twrp to verify that the app folder moved there and rename it to a better ID if you want. Also you better compare the app's permissions to another system app in that directory and match it up.
Reboot and if the directions were followed, you have systemized an app.
This works better than a systemized app, or a magisk/twrp module. Why cause twrp work is the hands-on management.
The droidware I recommend is.
Sdmaid (lookup apps given directory name.)
Orangefox (dual boot) cause I use it.
A file manager to check you work helps. Need root authority. I recommend the one I'll linkup.
In other roms and OSs the system directory for system app placement is just /system/app or prive-app.
Don't forget to mount the partitions before any working in twrp. I realized that about flashing and twrps modules running while I'm editing my system.
Sorry not adding links or apps good luck with it.
One other thing the boot animation.zip file for changing in located /system/product/media on Oxygen 11.
Ohh yeah theirs a app on play store called partitions manage. You can save any partition live while running you OS to a .omg file. If I do that after Systemizing some apps. It makese a system.img with them included. No more work to redo.
Well gonna go get beer or white pirate stuff. Lol
