I've created a Nandroid backup and transferred the img files to my Win7 PC for storage. Is it possible to mount the Nandroid img files with any Windows utility (to extract the files in data.img). It appears not to be iso or tar format.
Try power archiver or an image mounting utility like magic disc or alcohol.
Okay This Is My First Post Please Dont Flame
This Is For Every One Who Messed Around With Their deice and now cant log in and you have important data in the emulated internal storage which you need. If Yes the follow this simple tut
THIS METHOD IS ONLY FOR THOSE WHO HAVE A NANDROID BACKUP OR CAN MAKE A NANDROID BACKUP USING RECOVERY (i used cwm) IT CANT BE USED TO RESTORE ROM IN PREVIOUS WORKING STATE !! JUST DATA BACKUP
Lets Start..
1). Make A Nandroid Backup (usually created in the external sd) and copy it on the desktop of your computer
2). Download 7-Zip
3). Install
4). now open your backup folder there will be files with different file extensions (named like system data)
5). there will be many files we are only interested in files with extension .tar.ext4.a usually the biggest files
6). now those files are the image files of your internal sd and system
7). open 7-zip and navigate to your file (data.tar.ext4.a) and open it.
8). the fun part now.. now thats your root folder so navigate to /mnt/sdcard/
9). Viola! Its Your Internal SD now just select the file/folder you want
10). Select extract and extract to your required location.
11) And Its Done
This method is usually useful if you use audio manager and you havent changed the default data location from /sdcard0/Program Data/Languages/.fr
Enjoyy
Things had been going good for a couple months, and my internal media had been intact on my Nexus 5 for almost a year. So, after backing up kitkat using twrp, and installing the lollipop developer preview, everything was going fine. But after rebooting twice I found out that my data/media and /sdcard/ were empty, and es file explorer said that my data (nexus 5 doesnt have an sdcard, so es file explorer just looks at the sdcard folder) partition was almost full. So then I installed kitkat again after not being able to copy anything to my sdcard folder, and it created all new folders and everything, but es file explorer still says the data is their. Then, I used disk digger and it recovered all the photos and mp3 files from the data partition that dissapeared. But, what's really important to me is things like my backup, and the titanium backup files so I can have all my data from my apps.
IS THERE ANYWAY TO RECOVER ANY KIND OF FILE, I'VE DONE IT WITH MY COMPUTER WITH PROGRAMS LIKE RECUVA, BUT ANDROID PROGRAMS ONLY RECOVER PICTURES AND MUSIC FILES!? ANYWAY TO RECOVER TITANIUM BACKUP FILES FROM A PARTITION WHERE THE DATA IS STILL THERE TAKING UP SPACE, BUT JUST INVISIBLE?!

Sorry to bother you, but did you get my message?
@jeyaram06 how do I recover my data without special tools?
If you are not familiar making any major changes to the Android OS.
The first thing you should know what to do is Backup and Restore.
Make sure you have a valid All partitions backup and save on your PC.
Then you can make modifications, if anything goes wrong. Just restore it and all is same as before!
These steps will help you in creating a backup and be able to restore it to the same Tablet or any other HP TOUCHPAD.
How to create a Backup and restore using Team Win TWRP Recovery ( provided by Flintman ) Many Thanks to Flintman for his great work!
On the TWRP screen touch on Backup
Select the partitions to backup (Boot) (Cache) (Data) (System)
(Disable Skip MD5 generation during backup)
Select the storage (Internal Storage) (Micro SDCard)
Once the backup has completed.
Connect Tablet to Computer by USB
Go to the storage where you selected to save the backup files: (Internal Storage) or (Micro SDCard)
Go to
TWRP/BACKUPS/30N5HOIN9SAMLASPK9V41ADEBSR44B6B (that number will be different)
Select the folder under it, which is a folder with the date of the backup, Copy this folder to your Computer.
Let's assumed that the worse happened, the entire Tablet got wipe out.
To restore backup store in your Computer.
1. Create a new backup using TWRP as you did the first time, select any partition example boot. (It can be empty) (This is done to allow TWRP to create the folder structure and detect the files that you will copy to be restore)
2. Select storage, large enough to copy files from your previous backup that are on your Computer to the Tablet.
Go to the backup that was just created.
TWRP/BACKUPS/30N5HOIN9SAMLASPK9V41ADEBSR44B6B (that number will be different)
Delete the folder under it, which it has the date as the name.
Copy the folder store on your Computer
TWRP/BACKUPS/30N5HOIN9SAMLASPK9V41ADEBSR44B6B (that number will be different)
Select Restore
The backup that was copy from Computer (old backup) will be listed to be restore, in Select Package to Restore
Select all the partitions that you want to restore. All data selected, will be restore.
Many Backups can be created and save into PC and replace when need it.[/SIZE]
* Edited as per shumash suggestion:
Any other input is greatly appreciated!

You might want to point out that the backup and restore is done in TWRP recovery.
Hi,
I have a Wiko Lenny 3 phone and need to recover the pictures. The unlock code is lost, the touchscreen doesn't work anymore. My ideas so far:
1. I used the "Backup user data" feature of the stock recovery to a SD card.
Since I cannot upload an image until I have 10 posts, the recovery is like
"
Android Recovery
alps/full_v3702/v3702
6.0/MRA58K/1453981211
user/release-keys
Volume down to move highlight;
enter Volume up key to select.
----------------------------------------
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe data/factory reset
Wipe cache partition
Backup user data ---> this is what I used
Restore user data
Root integrity check
Mount /system
View recovery logs
Power off
----------------------------------------
SD card free space: 29564MB
User data allocated: 11893MB
backup file: userdata_20190929_172118.backup
Backup user data complete.
"
But how to access the data? Tutorials which I found didn't help (merging the files in Linux, remove 512 Bytes and rename to zip to be able to extract "some" data: it isn't recognized as zip file). Is it possible to restore this user data to a virtual device somehow to access the data?
2. Removing the code: Following a German instruction (I'm not allowed to link it, sorry).
ADB doesn't recognize the device. Probably because USB debugging is turned off and I cannot turn it on without unlocking the device.
I don't do this very often, so my knowledge about ADB and Android is limited.
Does someone have a helping hint? Thank you in advance!
Regards
Martin

Thanks. Is it possible to flash TWRP without losing data and without access via ADB?

If your phone has twrp available and it's a Samsung you can flash it and you won't be able to do a twrp backup without formatting data to have data partition mountable in twrp to flash decrypt zip to do a backup however you don't need to format to be able to mount system partition once system is mounted you can use the twrp file explorer to delete files to delete your screen lock so you can enter the phone

It's a Wiko Lenny 3, no Samsung. Sorry, I don't get it without punctuation.
Do I get it right, that
- If TWRP is available for my phone I can flash it, but I need to format all my data (no option)
- I can flash a "decrypt zip" to do a backup (what is it, where do I get it?)
- I can mount the system partition and can use the TWRP file explorer to delete files (how can I mount it?)
Thanks.
Problem solved, I could access all the data in the backup from the stock recovery!
This is how it worked:
In short: Make a backup of all user files in the stock recovery to a MicroSD card, put it to a Linux desktop, merge the backup files by skipping the first 512 bytes of each file, copy the merged file to Windows, extract it with 7zip.
In long:
1. I put an empty 32GB FAT32 formatted MicroSD card in the MicroSD slot of the Wiko Lenny 3
2. I used "Backup user data" from the Stock Recovery (see my first post). It took a few minutes until ~12GB of user data were written to the card. The stock recovery told me when it was done.
3. I copied all files (6 files, userdata_20190929_172118.backup to userdata_20190929_172118.backup5) to a Linux environment (Linux Mint 19.2)
4. The rest is explained in this video: https://www.youtube.com/watch?v=cY4cKKimEFU. If it is offline, I will explain here.
Do not use something like "cat userdata_yyyymmdd_HHMMSS.backup* > userdata_yyyymmdd_HHMMSS.backup" to merge all files into one because it will add the unnessesary 512 bytes header of all .backup files to the merged file. Instead copy all content except the first 512 bytes to another file and append the content from the other files to it, also by skipping the first 512 bytes.
5. This command will copy the content of the first file "userdata_20190929_172118.backup" to a new file "img.ext4":
Code:
dd if=userdata_20190929_172118.backup skip=512 bs=128k iflag=nocache,skip_bytes oflag=nocache,append conv=notrunc of=img.ext4
6. Repeat using the same command to append the content of all other files to the file "img.ext4" by skipping the first 512 bytes. Be sure to increase the number of the source file extention in the command. Next one therefore is:
Code:
dd if=userdata_20190929_172118.backup1 skip=512 bs=128k iflag=nocache,skip_bytes oflag=nocache,append conv=notrunc of=img.ext4
7. Repeat with all files
8. Copy the file "img.ext4" to a NTFS formatted USB stick or an external hard drive and go on with a Windows environment. The reason is that Linux will prevent opening some important folders
9. Install 7zip
10. Extract the file "img.ext4" with 7zip. If you are searching for pictures, you will find them in the subfolder "\media\0\DCIM\Camera"

I have the exact same problem with an older 2017 ALCATEL Pixi Unite A466BG. The code is lost and there's some photos we need off of it. I followed these instructions but when I got the img.ext4 file on Windows and tried extracting it with 7zip, I got an error that "ext4" is not an archive file.
I was hoping to see if anyone else had ideas of possibly why 7zip wasn't recognizing it? I had 3 backup files to merge (backup, backup1, backup2).
