[Q] Backup / Restore android "Accounts" only. - Android Q&A, Help & Troubleshooting

Hi everyone,
I'm looking for a way to backup and restore only the accounts in my smartphone (no apps or data needed).
I have Honor 4C rooted running android 4.4.2, and I'm planning to upgrade to marshmallow.
Any application or file to backup or to edit in system.
Thanks.

Any file like the one with WiFi passwords?

Make a NANDroid backup first then,
Make a backup of this file:
/data/system/users/0/accounts.db
Pay (massive) attention to permissions given to the file.
Because you have to set permissions after restoring it.
Any wrong permission set will end with failure, or maybe bootloop.

Help me to restore Titanium Bk data

It's a very bad time when you are not using WhatsApp. The thing is I was using s3 with root and many more. And I always use to take backup with titanium application. I took WhatsApp backup in my s3. Unfortunately in last week my s3 gets wet and now it won't work. But I have that backup file in my sdcard. Yesterday I bought galaxy a5 which I don't want root ri8 now. The main problem is I want restore my WhatsApp data. Because I was using my wp on my very old number and now I couldn't able to do verification of wp again. So I had this problem many time but now because of new phone it's very difficult to restore because tb ask for root access. I want to use my wp on my old number so please help me. Hw can I restore my tb data in my new phone which is not yet root..?
I have no full solution, but just an idea. In your TitaniumBackup folder, you should find a tar.gz file with the name of the WhatsApp apk. In there, you should find a data folder and then a /. folder, in which there should be the actual data used by WhatsApp. Then, if your new device accepts that, you should be able to push with adb these files and folders to the new data folder of your new installatation of WhatsApp.
I have never tested anything like that, so I don't take any responsibility, but it is an idea based on Helium from Clockworkmod which uses this trick.

Backup - restore whatsapp chats from data directory

Since last November, Whatsapp on my (rooted) Samsung Galaxy S3 Neo has been giving me problems: backups no longer work, it is impossible to download and upload multimedia. Also, I am experiencing random problems with other apps with file writing. So I would like to reformat the phone as much as possible and install a custom ROM (CyanogenMod being the first candidate).
But first I have to make sure that I can recover my Whatsapp chats, some of which are quite important for me, which is not trivial with backup not working. A bit of googling pointed me to a few people having similar problems; some of them managed to solve their problems fiddling with permissions and ownership on the backup directory, /storage/emulated/0/Whatsapp/Databases; I tried to do the same, but without success - let me just say that this attempt would be the subject for another thread. So I decided to try and simply backup the data directory, /data/data/com.whatsapp, having read that it was possible.
So I backed up the data directory to SD card using good old tar, then I renamed the original and restored the backup; having used tar, both permissions and ownerships were correctly restored (except for the symlink lib -> /data/app-lib/com.whatsapp-3 which was now owned by root rather than by user "install", but having permissions 777 I would be surprised if this was an issue). I also checked that the contents were exactly the same as those of the original directory using diff, and I deleted the app cache before trying to restart Whatsapp: in spite of this, it crashed before starting. I removed the restored directory, renamed the original one to its correct name, and whatsapp started correctly.
I am really confused: how is it possible that an exact copy of a working directory prevents an app from working? The only difference I am aware of in such a copy is in the inode numbers, but nobody would hardcode them in an application... I hope
Any idea, any suggestion is welcome. Did anybody every manage to backup ad restore whatsapp chats from its data directory?
Well, since your phone is rooted, which makes recovery very easy. You just need to find a good app. From my experience, you could apply to Jihosoft Android Phone Recovery. Good luck.

Need help restoring NFC app on lollipop.

I did a stupid thing.
Used titanium backup to uninstall NFC apk.
Tried to restore backup from TB and it would hang. Upon restarting, would constantly get error message that the NFC service has stopped (likely because restore was incomplete and a system function is trying to call it). Went into nandroid backup and restored by hand, the system/app NFC files and data/data NFC files, maintaining the permissions and structure. Reboot, same app can not be started errors.
Anyone got any ideas on what I'm missing? Full nandroid restore is a last resort.
Lollipop 5.1.1, Nexus 6, stock rom.

PLK-AL10 doesn't create backups on GDrive

Hello,
Today I got myself a new phone and I would like to move all data possible over from my old Honor 7. This is the PLK-AL10 variant so no Google apps were there by default. I have installed some things manually and Google Backups are an option in the Backup & Restore settings. Backup creation is on and the Google account is selected, yet no backups are created.
I have installed the compatible Google Backup Transport package and granted all the permissions it needed manually through the Permissions manager +made the phone ignore battery optimization for this one but still nothing.
Does anybody have a solution?
Kind regards
