Titanium Backup unable to delete system apps?

[CZ Eddie]

EDIT: SEE POST #8 FOR THE WORK-AROUND TO UNINSTALL SYSTEM APPS

Rooted last night and one of the first things I did was install TB so I could remove some of the system apps.
But while TB says they're removed (like Chrome & easter egg), I reboot and they're still there.
I did have latest BusyBox installed.
So I tried using TB's built-in BusyBox and had the same issue.
I also made sure to get /system_root Read/Write and still couldn't uninstall using TB.


Are we gonna have to wait for either SuperSU or TB to get an update with fixes.

Any suggestions on a way to get TB working? Other than manually removing apps via Root Explorer which I already know how to do and is not the point of this thread.

Isn't current root system-less.?

Root is actually in system_root and system is not being mounted rw?

If its true you cant change anything in system until it can be switched to rw..

I've already set it to R/W using this command: mount -o rw,remount /system_root.
Didn't help. The apps are still there after rebooting.

An odd thing I noticed. Titanium is showing "Android System Webview" and "Device setup 7.1" as frozen. And I didn't do it. Anyone else noticing this?

try system remove app

Just tried it. Doesn't work either.
Thanks for helping me rule out Titanium Backup specifically though.
Definitely something to do with Google's partition setup (or with root) then.

No big deal, I'll just use Root Explorer to remove the ~35 system apk's I'm trying to get rid of.
I just feel safer seeing app names rather than guessing at apk names when I'm removing stuff.
Plus, TB is just faster & more convenient. And I'm probably going to have to do this a few times over the next few weeks as I make & break my phone.

Btw, I'm a little disappointed there are a bunch of Verizon apps on my Google purchased phone.

DM-Verity, I think it is, is still active with this root. Think that's what your running into.

By the way, I found a work-around.

If you want to uninstall SYSTEM apps via Titanium Backup (or any other method), it helps to do the following first.

Open up a terminal session on your phone.

I use the free app Termux to do this:
https://play.google.com/store/apps/details?id=com.termux

Then type the following two commands:

su
setenforce 0

This sets SElinux to "permissive". Then you can uninstall all your system apps. Then after you reboot, the phone automatically goes back to "enforcing" for SElinux.

Works great. Doesn't screw up any of my user apps after removing the system apps I don't want (like Chrome, Messaging, etc).

If you want permissive on a permanent basis then check out this thread.
I haven't tried it yet, don't need to:

I really only wanted to backup, switch chrome from a system app to a user app, and restore data but couldn't do this using TiB until I ran these commands. Thanks!!!

this.. worked..

The workaround doesn't work for me. After reboot, selinux is back to 'enforcing' but the app still isn't Uninstalled.
However, thanks for letting me know about the apk delete method from system/app. It's the only method that works with some MIUI apps.

Yeah, setenforce 0 doesn't work for my N9100ZC (6.0.1)

What's working is, reboot into TWRP, choose Mount -> System -> Internal memory. TWRP main menu -> Advanced -> File Manager.
Make sure to delete the folder and subfolder of your bloatware (\system\app and \system\priv-app).

Hope this help

It seems that the workaround doesn't work anymore.
Have you find another one ?
