Hello to all.
My phone is locked on by forcing me to remove the battery. I rebooted the phone and you are stuck at the loading screen.
I reloaded the OS (version JW7_JW2_JW1) and recovery(version CF-Root-v4.4-XX_OXA_JW4-CWM3RFS) through ODIN, but the phone still does not start.
I booted the phone into recovery and made a backup. I was able to manually copy all the documents.
From the backup of the recovery, through the tool unyaffs, I recovered the contact database (contacts2.db).
Now I started the trouble because I can not find the message database. I have read that you should find in the folder com.android.providers.telephony, but the folder is empty.
Fearful of losing these files, I used the tool ddrescue as follows:
Code:
sudo ddrescue -r 3 /dev/sdb /my_path/image /my_path/logfile
I then mounted the file image with the command:
Code:
sudo mount image /mnt
To my surprise, I do not see all the hidden files that is able to recover the recovery.
Do you think that I've lost forever the phone's message?
Thanks in advance for any help you will be able to provide me, hello to everyone.
PS: I apologize for any inaccuracies or technical errors, but they are new to this type of work.

Hello to all.
I was able to recover and restore the data of the Memo. The database is located in the folder com.sec.android.app.memo
No one has an idea on how to restart the phone and try to recover / export of SMS?
Thank you all.
Hi all. Phone is rooted and unlocked. Have twrp installed. Made a twrp backup, downloaded a new ROM (aosp). Wiped phone as in op, flashed new ROM & gapps. Upon restating, phone asked for password. I'd made sure that I'd got rid of security seetings before making backup. Tried to reinstall backup, phone boots into startup screen, then again, asks for "to start android device, enter your password". Please help.
Try deleting this file in twrp using the file manager.
/data/system/locksettings.db

Hi many thanks....but when I go into file manager, there is no file for data????
I think I've killed the phone. Any way of completely wiping and starting again?
The 3 buttons at bottom of screen. When I press the right button, message I get is:
Failed to decrypt data.
Unable to decrypt with default password. You may need to perform a format data.
Updating partition details....
.....done
Unable to mount storage
Full selinux support is present.

Glad you came here, it is simple to solve this.
1. put your device into bootloader mode
2. connect your device to pc via usb
3. install minimal adb and open command prompt in that minimal adb folder.
4. enter command - fastboot erase userdata
5. solved. but sorry, it will wipe your internal memory too.
you can even try wiping data with twrp, but it'll usually won't work at this stage. so follow the command. cheers.

Simply flash supersu 2.79 from the XDA thread, everything will be back alright.
I'm trying to do a backup using this adb command:
Code:
adb backup -apk -noshared -all -nosystem
I need to make an adb backup so that I can restore the backup on a non-rooted phone.
However, when I enter the command, the cmd window only gives an output saying "Now unlock your device and confirm the backup operation", and then ends immediately, leaving a blank (0 kb) backup file.
I then checked the logcat and saw an error message saying "unable to launch full backup confirmation".
I've tried rebooting and still, no luck.
Does anyone know why the backup confirmation screen just wouldn't show up on the phone? I really need to backup my apps and restore them on a non-rooted device so adb backup is my only option.
The rom I'm using is Candy5 ( https://forum.xda-developers.com/xpe...andy5-t3196185 )
Solved by myself.
It turns out the rom doesn't have the package 'com.android.backupconfirm' installed. So what I did was doing a twrp backup first, flashed the last snapshot version of CM 12.1, used 'adb pull' to pull 'BackupRestoreConfirmation.apk' from '/system/priv-app/BackupRestoreConfirmation', restored the backup, copied the apk to the same directory and rebooted. The backup confirmation screen finally shows up and I can do backups now.
Hi Guys.
Excuse my english
I have with ADB and the command
adb backup -all -apk -shared -f d: \ backup.ab
created a backup of my phone. According to the phone in the end, this backup was also made.
I also find under the drive D made the backup.
Then I had to reset the same phone to factory settings.
So again I have with ADB and the command.
adb restore d: \ backup.ab
The recovery started.
This can be tracked on the phone also, you can see how he restores the backup.
At the end, the message "Backup successfully recovered" appears on the phone.
But there is no change on the phone.
What am I doing wrong?
Or what can I do? In order not to have to do everything again from scratch.
Thank you for your help.
I backed up dtbo partition and then tried to backup other partitions but it's giving me this error and failing. I'm using the trwp that I got from the xda twrp flash guide. Please help.
Anyone?
same prob on k20 pro still no solution. RIP
I had the same problem and a simple solution:
Copy your TWRP backup from phone to you PC.
Install the ROM you would restore, after boot set your pin/pattern.
Reboot to TWRP and TWRP asks for your pin/pattern.
Copy your backup back to phone.
Restore backup.
It should work now.
Maybe check the twrp log.
I had the same error and it was because i had dual app feature turned on for an app.
I also read it can happen even if you don't use that feature.
