[Q] Any way to delete all messages without going in the app?

Is there anyway to delete all the SMS and MMS messages without going into the stock app itself? Like is/are there any file(s) that I could delete using a file manager?

You can go to Menu - Settings - applications - Manage Applications, find the app in the list and tap on it, and then select clear data. This will wipe out the messages, but it will also wipe out all of the messaging apps settings.

Or you could download an app like SMS Quick Delete and use it.

[Q] Titanium setup to ignore music cache

Anyone know of a way to stop Titanium backup from backing up cached music or skip just one app? It is backing up my Google music app. which I have set to a cache of 2GB and making for a ridiculously large backup file.

Backup/restore > menu > preferences > uncheck backup app cache

[Q] how to disable google talk?

What's the proper way to disable it? i don't use it and i kept on receiving notification from spam user request.
i tried go to settings-apps and disable google talk & disablot notification, but i still get notification! i also search that i shouldn't uninstall it thru titanium backup as it will cause other problem to android.

Just uninstall it with titanium ! I used to uninstall it and i had never had any other problems. Try and otherwise restore it and look for a different option
Or just take out the Talk.apk in the system\app dir and copy it to your sdcard.

You can also disable the notification in Settings
Settings -> your email -> notification -> Disable

createTarFork() Error while backup the data partition.

Hey guys here,
I've got a problem with my OnePlus 5T a while now. I used to make weekly nandroid backup (ye im rooted), but about 3 weeks ago the backup of the data partition via TWRP stopped working. Every other partition works, but data dont. Now i want to test a custom rom and wanna be able to switch back to oos without losing data.
I got the error
Code:
createTarFork() process ended with ERROR: 255
in twrp, so I pulled the recovery log via adb and i got this:
pastebin (dot) com/7Vvfx7sM
Sorry for the link, the ****ty outside link detection system found some links in my log
If I should provide more data tell me, I hope you can help me!
Greetings,
tooxo

This might be because of Parallel apps. See below links for more info.

you need to turn off parallel apps, then go into a root explorer and delete
data/system/999
data/system_ce/999
data/misc/999
data/misc_ce/999
data/user/999
data/user_ce/999
This will allow you to do a backup, but you'll get "extractTarFork() process ended with ERROR=255' when trying to restore. So it feels kind useless, unless someone can figure this out.

going to test out

I could resolve my nandroid /data backup error on my EMUI 8.0 Mediapad M5 device with those following steps:
1 - Use a correct TWRP implementation
TWRP need to access the uncyphered partition /data.
There no possibility to backup it, if TWRP does not implement deciphering user data partition.
2 - Remove all users except user 0 (the administrator)
You can verify that there is no unwanted users, looking at directory /data/user : the only subdirectory should be "0".
To remove the others users :
Remove the PrivateSpace if you have one (Settings > Security & Privacy > PrivateSpace, and tap on the garbage can).
Remove all the secondary users (Settings > Users & accounts > users, and tap on each users to delete them). Keep just the main administrator user.
On EMUI, remove all twins applications (Settings > Apps & Notifications > App Twin, and disable all twin apps).
On OxygenOS, remove all parallel apps (Settings > Apps > Parallel Apps, and disable all parallel apps).
On MIUI, remove all dual apps (Settings > Dual Apps, and disable all dual apps)
On others devices ... you must find all parameters that create those unwanted users.
If you are not able to get the correct settings to suppress those users, in last resort you can try this command : "pm remove-user user-no. (For example "pm remove-user 999").
3 - Do not forget to protect your backups by a password
This would be stupid to cipher your /data partition and keep backups of this partition unprotected.
These steps fixed the nandroid backup problem for /data partition on my Huawei Mediapad M5 device.
I post on this forum because I hope that this will be helpful for others devices owners.

[solved] Disable rom update notification? Clear OTA cache?

I would like to disable update notification. And clear already downloaded update files.
I have tried to freeze update system apps without success. Any idea, experience?
Thank you!

Update
TidyPanel (pro) sopved the notification.

Now i just want to delete cached update files. Where i can find in the file system?

I have found the place of OTA files here:
/storage/emulated/0/.Ota

More space optimisation.
If you don't need official wallpaper, you can remove:
