Unable to Delete System Apps on Marshmallow using Titanium Backup - Nexus 7 (2013) Q&A

I've just installed Marshmallow on my Nexus 7 2013 wifi using the Nexus Root Toolkit and rooted using the beta version of SuperSU.
As I understand, there is almost no space left on the system partition. And I've read suggestions that you use Titanium Backup to delete an a system app such as Google Play Games to give yourself some space in the system partition. (and then reinstall the app in the user space, if you want it).
I'm not having any luck with deleting the system app using Titanium Backup. The Processing dialog just stays up forever. And after a reboot, I tried to to convert Google Play Newsstand from a system to a user app, and again the Processing dialog just stays up forever and a reboot was necessary.
Is there something I'm missing or something I need to do in order to free up some space in the system partition? Thanks.

It should work. You flashed the boot image right?
I flashed chanifires modified boot.img and then the 2.52 beta through twrp and was able to delete system apps with TB on mra58k (didn't try on mra58u).
You can try flashing the system.img and then redo the steps above and see if that works. You won't lose any data flashing system.

Thanks. Reflashing the system fixed the problem.

I must be doing it wrong - Titanium Backup Pro

I am having fits trying to use Titanium Backup Pro (TBP) on my Samsung Galaxy S3 (i747). After installing a new ROM and preforming a TBP restore I always have two problems. First my wifi and 4G(LTE) fail to connect. Second, I can no longer install apps in Google Play store from my desktop PC. Before I do a TBP restore both these problem do not exist. What am I doing wrong?
First I will walk through my process of installing a new ROM.
Place ROMS & GAPPS in the root directory. I put them there because it is quick and easy to find.
Backup my current ROM using ROM Manager Premium v5.0.3.1.
Backup all my apps, folders, and settings with TBP...I think. I choose the Backup all user apps + system data option.
Here is where some of the confusion is for me. Which backup option should I chose in TBP?
I have tried both Backup all user apps and Backup all user apps + system data.
Or should I choose another option?
Does TBP backup all my folders I created on my homescreen and other screens?
Does TBP backup all my WiFi connections and passwords?
Does TBP backup information pertaining to Google Play?
Does TBP backup all my widgets on my homescreens?
Does TBP backup the wallpaper currently in use on the phone?
After all the backups I boot into Recovery mode using ClockworkMod 6.0.1.2.
Once inside CwM Recovery I select wipe data/factory reset, wipe partition cache, wipe dalvik cache, and wipe battery stats.
Next I install the ROM and GAPPS. After they both successfully install I reboot the phone.
Finally I go through the setup process to complete the new ROM install.
I have tried both letting Google Play restore all my apps and stopped Google Play from restoring my apps.
At this point my WiFi and 4G(LTE) are working fine. Plus I able able to install appsin Google Play from my desktop PC.
Now I preform a TBP restore. I have tried both Restore all apps with data and Restore missing apps + all system data.
Once the restore is done TBP recommends I reboot, which I do.
Sometimes the phone will get stuck in a boot loop. So I have to pull the battery and reboot. Sometime the phone will get stuck in boot loop and the only way to get out of it is to reinstall the ROM and GAPPS.
After the TBP reboot I notice my WiFi and 4G(LTE) are not working as well as installing apps from my desktop PC.
I hope you guys can help figure out what is going on.
Thanks,
-Sonny
Only thing I can say is never restore system apps. I always use TB and have never had an issue.

+1 to this. Never restore any system apps.
The only system data I restore is clock and contacts storage.

[Q] A question about TWRP and Simple2Ext

Hello everbody,
I have some questions related to TWRP. What I am aiming for is trying out new ROMs to see which one suits best my needs. For that I need to do a full backup of my system. As far as I know this is what TWRP is supposed to do this.
I just did some tests and it turned out that this is not the case - I created a full backup using TWRP (checked all checkboxes in the backup creation window). This is the place to mention that I use Simple2Ext to move all user apps to sd-ext. So I assumed that TWRP will manage to restore the whole system as it backs up all partitions (incl. sd-ext). It seems though this is not the case - I just recovered a backup but the system contains only the system apps (Calculator, Gallery etc.) Not even Google Play Store. All user apps (including S2E) have an SD icon in the Apps settings and when I try to start an app from the desktop, it says App isn't installed.
What am I doing wrong? How can I make a full backup which I can restore and have S2E working? Is this possible?

It seems that it did a only-system-partition backup. Don't know if that's the only backup function with TWRP, but as it should be based on CyanogenMod recovery, it should support a full backupt (including every partition). I suggest to write in development thread.

[Q] CWM didn't restore data well.

Hello, I have CWM for long time but that's second time when I used it to restore my stock firmware with apps from a backup made before changing a ROM.
I was using Cyanogenmod 12.1 and before it I did backup of my stock firmware by CWM.
The problem is, when I did restore from a backup, It restored system well, but ... not exactly data.
System booted well, but I don't see any of my apps. Hovewer, when I check in App Manager, I see many apps that i HAD installed but they are shown as 0,00 B weight and have "android" icon.
Memory of my phone is filled as same as when I did backup but apps don't show.
How should I use restore from backup to restore entire system well?
Go to recovery and wipe data,cache and dalvik. Then use advance restore option to restore data and cache.
Now data should work but I recommend using folder mount or sd fix to modify the sdcard restrictions on stock kitkat.

Titanium Backup can't perform changes in the SYSTEM partition [Lineage 14.1, Supersu]

Hi,
I have recently replaced my LG G3 stock rom with Lineage 14.1 official rom. I have also rooted my device using the 'su-addon' suggested by Lineage team.
Unfortunately, since I moved to Lineage some of Titanium Backup's features have stopped working properly. For instance, I tried to uninstall some system apps, and after reboot they were still there. I also tried to convert system apps into user apps, but Titanium Backup couldn't accomplish the proccess (I had a message telling me "Please wait" for more than 15 minutes).
However, Titanium Backup does succeed in taking backups (for both system and user apps). Another interesting fact is that I managed to uninstall system apps / convert them to user apps manually, by using a File Browser with root access. Therefore I really don't get why titanium backup stopped working....
My guess was t. backup doesn't work properly with Lineage root addon, and thus I replaced it with SuperSu (latest version). Still, titanium backup doesn't work... It looks like it fails in each action requires to change files in the system partition (maybe it doesn't have write permission?)
Any suggestions?

[Solved] Restoring apps in data after switch to LOS

Hello guys, I'm thinking of switching from MIUI to LOS or Syberia. To do that I need to format the /data partition. I really don't want to re-install all my apps again, so is there a way to restore the data partition not as an image, but as file structure? I have TWRP backups but they're images of the partition. Do I need to install Titanium Backup or similar?
What would be the best course of action here?
Thanks in advance!
Try migrate on play store

Play Store indeed has a list of all the apps I have installed. However all the data that's in the app's settings will be gone.
Here's an example - I use a Launcher app. If I re-install it from Play Store, all icon arrangements, wallpaper settings, all other settings within the Launcher will be gone.
What I'm trying to achieve is once the /data partition is formatted, ideally I'll just need to copy paste the data (files and folders) back in again. Partition restore won't work as it will mess up the LOS (or any other non-MIUI OS) installation.
The TWRP backup gives me an image file, which can be extracted to apps and folders, but I'm not sure I can just copy paste that over to the /data folder(partition). Main concern is permissions. Would they be automatically set on OS boot?

Titanium backup is hard to beat. You can copy your back up folder onto your pc and copy it back over after the wipe to restore your app data.

He actually means Migrate as it's an app on Play Store. The app is sort of like Titanium Backup but free.

Thanks, I misunderstood the reply. Migrate indeed looks like the app that will do the job. I'll give it a shot.
Thanks again!
Quick update - I am now on LOS 16 and used Migrate. A few apps gave errors (Telegram is one of them) so I uninstalled and installed them back from Play Store. But that's nothing really. I loaded the launcher amd saw all my icons back where I left them... Amazing!
