Hello everyone,
I am having an issue with the Bass Booster app after I made it a system app. I did so through Link2SD. After the conversion, the app just disappeared from the app tray and it was no where to be found. I finally found it in the data folder of my root browser and changed the permissions to rw-r--r-- and rebooted my phone. Still the app doesn't appear in the app tray. Any help would be appreciated.
Thank you! :)

Uninstall/remove/delete it then boot to recovery and wipe cache then reboot and reinstall it like normal.

Edit: in your screenshot, it shows the folder but it has no icon on the folder, that means the app is no longer there, look in the bass boost folder, I'll bet it's empty but there's supposed to be an .apk file there for the app.

Is there a bass boost folder in /system/app or in /system/priv-app?

Yes. I found it in system/priv apps
If you have custom recovery, boot to recovery and wipe oly the cache and Dalvik/ART cache, DO NOT FACTORY RESET.

If you have stock recovery, boot to recovery and wipe cache partition, DO NOT FACTORY RESET.

If you did everything correctly, this should reload the app.

Okay so I delete the .apk file and then go to TWRP and wipe cache right?

No, I think you might be alright if you just leave it and boot to TWRP then tap the "wipe" option, then tap "advanced wipes" then select cache partition and Dalvik/ART cache, then slide the slider to wipe them, do not wipe system or data, only the caches, then reboot. If you have everything right it will load the app as a system app and be in app drawer, if it isnt, let me know.

I think you may have only missed that one step, any time you are adding apps to system or removing apps from system, you have to boot to recovery and wipe the caches then reboot.

Yes I missed that step. I will clear the cache and get back to you
Can you tell me if any app when converted to system app misbehave or crash?

Sometimes, it depends on the app, the device it's installed on and/or Android version. No way to know for sure which ones unless you try them.

Hmm. Delete it from /system/priv-app, if it's in its own folder in /system/priv-app then delete the whole folder, then go to /data/data and delete the bass booster folder.

Then boot to recovery and wipe the caches again, then reboot, reinstall bass booster.

Then install ES File Explorer, enable root explorer in ES File Explorer, then mount r/w permissions, then go to /data/data, find the bass booster folder, press and hold on the folder(do not open the folder), tap the "more" button, select "move to", navigate to /system/priv-app, place the bass booster folder in /system/priv-app folder, then exit ES File Explorer.

Then reboot to recovery, wipe both caches, reboot.

Then send if it's working right, if not, go to /system/priv-app and make sure it has system app permissions.

Sir I am facing problems with ES File Explorer. It just disables the root explorer and says that there's some problem. This is the reason why I am using root browser instead of ES file explorer

You aren't properly rooted then or something.

Use root browser then, just move the whole folder(not just the .apk), make sure app permissions are correct. Then after you move it, boot to recovery and wipe caches then reboot. This is more reliable than using links2sd or other apps to convert apps to system apps

I am properly rooted. I checked that and if I wasnt, the rest of the apps requiring root wouldnt have been working.
The permissions should be rw-r--r-- right?

Yes, rw-r--r--

Sometimes, root checker says you are rooted and root apps work but there will be some root processes that fail, these devices are partially rooted. It happens a lot with devices that use Kingroot or Kingoroot.

    Probably, su binaries have to update after opening it for the first time.

    I was able to delete the file using Root Essentials root browser. I reinstalled the app successfully. Now I dont know if I should try and convert it to a system app again cause I have wasted more than two hours behind this :confused:
    But thanks for helping me out atleast I could get the app working again. I owe you :)
