Titanium Backup (TiBu) Uninstall Not Working | Oxygen OS 10.3.2 | Magisk 20.4 - OnePlus 6 Questions & Answers

Hello OnePlus XDA Family. Hopefully someone can help me. I have just received a OnePlus 6 preloaded with Oxygen OS 10.3.2. I have rooted it and I am now trying to debloat it with TiBu but I am not able to uninstall any of the system apps. I receive the following error message every time I try to uninstall 'Cannot remove system app | Failed to locate the apk file.' I can only guess why this would be happening, perhaps it is android 10? the a/b partition thing? Is any one else having this issue? I have searched to no avail. Kind regards in advance

Yes... I do understand your frustration but I can confirm that titanium back up can't uninstall some of the system apps (mainly bloatware).
I suggest you the ADB way using a pc and a USB cable.
Follow this page (it works with rooted or non rooted phones)

You could use Terminal Emulator Debloater, Swift Backup, or just freeze the apps instead of uninstalling them.

[Guide] Backup Apps & Their Data for Rooted & Non-Rooted Devices

[Guide]
Backup Apps & Their Data for Rooted & Non-Rooted Devices​
Purpose: Let's say that you made a high score in subway surfers and you don't want to lose it, then you'll need these two apps to backup the game data.
Helium (Without Root Method):
Helium is an application by Koushik Dutta, who has also developed CWM Recovery.
Important Note:
Motorola devices are not supported due to a bug on Motorola’s part.
Requirements:
1. Rooted or unrooted device with android 4.0 or higher.
2. Computer and USB cable.
3. Helium on your android with Helium desktop app on your computer.
4. If you're using Windows, you've to install ADB drivers, but if you’re using Linux or MAC OS X don’t worry about this issue.
Helium - App Sync and Backup (Play Store link)
ADB Drivers and Helium desktop app
Instructions:
1. Run Helium desktop app and Helium on your device, then connect via USB cable. Wait just a few seconds, and Helium will be enabled. You can now disconnect your device.
Note :If you reboot your device you'll have to reconnect it to re-enable the app.
2. Now to backup, you must select the desired apps and games then click backup. You can select one by one or swipe up the bottom tab to select all. You can backup the app data only to make the backup less size but you must to redownload when restoring or you can back up data with apk (this is pretty helpful but with more size).
3. You can restore on your current device or on a new device using the same sdcard. I think you can also copy /sdcard/Carbon folder from the current sdcard to the new sdcard to restore.
- You can make schedule backups
- If you run to the premium version, you’ll be able to backup and restore from cloud storage.
Titanium Backup (Root Method) :
If you've a rooted device, you can benefit from Titanium Backup automation and flexibility without caring to android version. This app is more featured and works without connecting to computer.
Requirements:
1. Rooted device.
2. Titanium Backup on your android.
Titanium Backup ★ root (Play Store Link)
Instructions:
1. Start Titanium Backup and grant root permissions.
2. You'll see 3 tabs. Enter backup/restore page. You can now see a list of system, uninstalled and user apps which can be filtered.
3. Here you can manually select which apps to backup and restore.
4. Let’s say you want to run a full backup. Select the button on the top right of the screen (batch button) and you'll see many actions. Run “Backup all user apps” action. You can select what do you want to backup or select all. After figuring, tap the green checkmark.
5. For making a full restore, you can enter the batch actions and run “Restore all apps with data" action. The free version will make you press a yes dialog box for each app you want to restore, but the premium version does it all behind the scenes.
Important Notes:
1. Restoring system data can cause serious problems.
2. Restoring system data from one device to another will definitely cause problems.
- You can make schedule backups
- If you run to the premium version, you’ll be able to backup and restore from cloud storage.

Super Backup makes backup for sms & contacts, where Titanum Backup and Helium makes backup for apps and their data (like a saved game in Angry Birds).

OK, you're right, but it requires root. Non-rooted devices need Helium to backup app's data.
Any way, if my guide helped you or you liked it hit THANKS.
I have been trying to get Helium Desktop to install on my Windows 8 64bit PC and keeps giving me a missing DLL error and won't install! I have been searching the internet for days now and all I can read is that others have the same problem, but no one has posted a solution! I'm at wits end on this one! How do you get it installed and where can I find this missing DLL!?!

I had the same problem. It was related to having the Use as Media Device setting checked in the options. Once I unselected it the DLL files downloaded and installed. I don't know why but give it a try and see if that helps.

Very good alternative to Titanium, I usually use Titanium along with a Dropbox account, but this can more, great stuff.
Helium and MDM
While Helium was a fabulous tool for backing up from one tablet and restoring to another, I've encountered an odd problem. The original tablet was rooted, but I used Helium in non-rooted status. Then I restored to a non-rooted tablet. Thereafter, I installed AirWatch MDM only to be told by AW that the new tablet is rooted. I've confirmed through various means that the new tablet is not rooted. However, I suspect Helium does something that trips a flag. Does anyone have any idea on how to clear the flag so that my unrooted tablet will look unrooted to AW?

Hey, you can simply see the requirements in the OP
Helium works with rooted and unrooted Android devices but needs 4.0+. I think it won't work with ginger bread even if you have root. I hope that I helped

Hi maw,
Did you find a solution for this ? I have the same
Are there any apps that allow you to backup to your desktop? I want to be able to individual backups of the apps I currently have installed, delete the ones I don't use(I need the free space), with the much faster option of just sideloading them instead of having to redownload them from the play store. I don't have enough space on my tablet or phone to make Titanium or Helium backups. Thanks for any recommendations and help.
Edit: NVM found one
Insufficient permissions
When I tried running the shell script on Linux Mint 16 64-bit Petra, it just said
Code:
error: insufficient permissions for device
First I had a problem that the script required changing permissions of the script and adb, but that was not a big of an issue. This however, I don't know what to do with this. USB-debugging was enabled and device was connected.
Edit:
I got this working. I configured the USB-access in udev as per instructions of source(dot)android(dot)com/source/initializing.html#configuring-usb-access. Then I modified it's permissions to read-and-write
Code:
sudo chmod a+r /etc/udev/rules.d/51-android.rules
and then I also restarted udev by
Code:
sudo service udev restart
That did the trick and I managed to connect the device.
Problem on Windows 8.1 64 bit
Hi Guys, I've just upgraded my OS to Windows 8.1 64 bit, and each time I tried to connect my phone the OS haven't recognized the device. I looked at the device manager and I discovered a generic Android driver provided by Helium.
So I unistalled Helium, restored the USB drivers by Samsung Kies, and now the OS recognized my phone again.
WHy?
Thank you!
Antonio
Thanks for being here, forums, when I need to do something simple and just have a senior moment
Very often, I reset my data on the S3 for try new ROMs, and, every time, I have to re-download all the applications...
Can I backup last version of Helium APP (APK?), so I can install it after the first boot and restore applications?

[Q] How to disable/uninstall preloaded NVIDIA apps?

I know you all are going to think I'm ridiculous, but I bought 2 shield tablets for my kids ages 3 and nearly 2 for educational purposes. After weighing the Nexus 9, shield tablet and Sony's Z2 tablet the shield seemed to be the best value. My kids have a restricted profile with only the educational/learning apps that I have selected available to them. My question is how do I disable or uninstall the preloaded NVIDIA apps such as SHIELD HUB, the controller one, Twitch sharing, etc.? My kids will never use them likely for the usable life of the tablets and I don't need them poking around with them so I'd like to have them removed or hidden at the least. I have the tablets stock rooted with TWRP recovery and I've used Titanium backup on previous devices to do something similar before but it doesn't seem be to able to located the APKs of these apps to uninstall them.
Thanks for the help!
Go into Settings and then Apps, you can select which you want to disable and uninstall (will not always uninstall as its part of the system i think) This is what I have done as i dont want junk running when I dont need/want it to

I tried that first before resorting to Titanium Backup. The Disable button is greyed out and not available to click for these apps. These are like some super system level apps that can't be disabled or uninstalled the normal way.

My suggestion would be to root the device. Many apps such as Titanium require root access for full functionality. Once rooted you'll be able to remove anything that you want. I personally just use Root Browser to navigate to System/App and delete what I don't want.
The drawback to rooting is that you won't have automatic OTA updates. (Not hard to get past that, download the OTA file and flash in Recovery.) But for your use you might not want to receive OTAs anyway.

My tablets are rooted, I mentioned that in the original post. However, Titanium Backup was unable to uninstall them (thus my question here) saying something about being unable to locate the APKs. I'll try Root Browser manually like you suggested when I get back home to them later.
I'm fully aware of all consequences of rooting, OTAs, etc. Every Android device I've owned since the original T-Mobile G1 has been rooted, but I do appreciate your willingness to help!

Got it, I misread the part about being rooted and your experience on previous devices.
I stopped using Titanium Backup a while ago. There are simpler means of restoring apps and restoring data is likely to cause headaches. That said, the problem seems odd. As far as I know, all apps install to either /system/app or /data/app, That being the case, can't imagine why TB wouldn't be able to find them.
Are you by any chance running Multirom?

Not running MultiROM, just stock with root. I thought it was odd that Titanium couldn't locate the APKs too, that's why I decided to ask here. I suspect if I go cruising around /system/app looking for these APKs to remove I won't find them there.

You would be correct about them not being in system. Look in /vendor/app. Should be what you want.

fix/bypass signatures do not match the previously installed version

So i need to back up app which has backup function disabled, so i decompiled app, changed backup to true and compiled, app installed and i could back it up with adb but data was gone, i needed to keep /data/data/com.myapp so i did, with pm uninstall -k and it kept data but now i can't install my modified version, it gives me error "signatures do not match the previously installed version" is there any way around this?
i don't need some root solutions, my goal is to back it up from pc with adb without root
i also tried to extract data with app not installed, but didn't work, what tells phone not to back it up if app is not installed? data itself?
EDIT: oh boi, i just realised this is general thread, can't delete or move, mods please? xD

Can't delete bloatware

Hi guys,
So I just unlocked my phone using xperifix and I tried to delete all the bloatware using 2 apps I found in the play store but I was unable to. The phone just tells me the uninstall failed and i dont even know why
Any idea why this is happening?
thanks

Titanium Backup is possibly the best app for a rooted phone. It will uninstall any app.
You can go into TWRP, mount System partition, then hit the FileManager under Advanced, and then change permissions/delete files/folders accordingly.
But be careful, there seems to be some wierd dependencies going on in there, and you end up with some random FCs here and there after removing bloat app folders and such.
My personal advice if you want to be free of headaches, just 'freeze' the apps using say 'Advanced Tools' from appstore (my recommended app freezer and general swiss-army tool).

Titanium backup: Apps crash after restore

Migrating to a new phone and discovered an issue with the backups on my old phone. This is tested and happening on both btw.
If I backup and restore a working app it then will force close on opening. Clearing cache and data and still force closes.
I tried uninstalling titanium, deleting titanium folder and reinstalling.
Same issue after a backup and restore of an application.
Running Oneplus 6 and Oneplus 7 pro
Unlocked and unrooted with magisk
Titanium at latest version from market.

App restore with titanium doesn't work for switching to a new phone, only restoring to the same phone and same os. When it does work the apps tend to be super glitchy. I'll drop a link to the xda thread where you can get more info/ help. Good luck.

Agreed. I've only migrated app data to a new phone using TB import/export (.TiBkp) feature. AFAIK, you can only do that one app at a time. So I've only done it with a few apps that I really wanted to save the user data.
More folks on this forum are recommending Swift Backup these days. It seems more reliable for this phone. I've use TB for years, but now I've just started trying out Swift Backup.
It appears TB is not compatible with the newer "split apks" format for newer apps in the appstore.
Basically TB will only backup the "base.apk" for an app when it does a backup. But with split apks, there are other APK files besides base.apk, like one for the app's language (split_config.en.apk) or the cpu type (split_config_arm64_v8a.apk) and the screen resolution (split_config.xxhdpi.apk).
So, since TB does NOT backup these extra apk files, these files will be missing when you do a restore with TB and thus the restored app will crash when you try to run it.
Luckily there is a new open-source backup app that works well with Slit-apks on Android 8+:
GitHub - NeoApplications/Neo-Backup: backup manager for android
backup manager for android. Contribute to NeoApplications/Neo-Backup development by creating an account on GitHub.
github.com
And I think it's better then Swift backup because:
1) Swift backup requires your google account login
2) Swift backup throws errors if you block internet access to it for security reasons
3) Swift backup is not open-source, so it could go the way of TB in the future.
4) And OandBackupX is FREE

So I tried this app and maybe you can help me out and tell me why after trying a restore I ended up with all of these errors , any advice or hints would be great,,,also prior to attempted install I was rooted and about 40 plus apps installed fine,
Swift does not give me these errors

Those errors seem like there is a problem with xandbackupx not being able to gain root access.
When you first started OABX, it has a bunch of cards where each card requires a different permission on your device - did you go through each card/step and give all those permissions, including root?
Are you using android 8+?

Thanks for the reply,,, yes I checked all and granted all permissions, Iam on a11 firmware running a a12 rom Bliss, ,, I will mess with it some more with it , it looks really robust with alot of options so maybe one of the settings need to be ticked or maybe it's just this rom, it's not a big deal as I have the other one to fall back on until I do some more testing
