[GUIDE] Internal Memory Data / Deleted Files Recovery - Galaxy S 4 General

This is the same tutorial written by Wartickler at this link. Thanks for his efforts, his work is appreciated.
Here we bring minor changes to the tutorial for those of you who are facing problems accomplishing the procedures.
The Problem
Internal Memory doesn't mount as a drive like external memory does. External memory would allow you to use data recovery tools that scan for deleted files and return them to a usable state. These tools work because most operating systems don't go through and set all of those 1's and 0's to just 0's when you delete a file. Usually the operating system will just delete the reference pointer in the index that says that a file exists with such-and-such name and it's located at this position on the hard disk / memory location. There are destructive delete tools out there that will overwrite the spot of a deleted file multiple times to discourage recovery in just this manner. The issue is that data recovery tools need an actual mounted drive in order to dig deep and unearth those funny pictures of cats you so tragically deleted by accident. These newest batches of phones don't have external SDcards which are super easy to mount as drives. Internal memory mounts as MTP/PTP which is not treated as a mounted drive and cannot be scanned by these data recovery tools. But still there is a hope.....
The Process
My phone is the Samsung Galaxy s4 (GT-I9500) though I imagine this should work for ANY phone with Internal Memory. We will be using a Windows 7 machine to:
back up the entire internal memory partition to your computer as a single, massive .RAW file,
convert the .RAW file output to a VHD,
mount the VHD as a disk in Disk Manager,
scan the attached VHD volume for files that have been deleted and recover them,
The Requirements
A rooted Android phone, (try to root with a non-destructive method as this appears to protect those who must root from wiping the device data a second time),
BusyBox installed on your device,
Cygwin installed to [c:\cygwin] with pv and util-linux from the repo (at the package selection screen search for pv then util-linux and click on Default to change it to Install). Make sure to open Cygwin once to make sure that the /bin folder is created. Also, I made a folder at [c:\cygwin\samsung] to put the exported .RAW file,
Netcat (download the ZIP file and extract nc.exe to [c:\cygwin\bin]),
ADB - You can use minimal adb and fastboot which is 2MB only. Attached, find the link at the bottom of this post. (make sure adb.exe is in your path. Path is in System Properties -> Advances -> Environment Variables -> System variables -> Path and add to the end: ";C:\Program Files\Android\sdk\platform-tools" or where ever you placed your adb.exe),
USB Debugging enabled on your device,
VHD tool from the mighty M$. Put the VhdTool.exe file in [c:\cygwin\samsung],
Piriform Recuva or your favorite data recovery tool, (it appears Recuva only finds the more common file types like images, videos, etc. Those were the file types in which I was interested. If you are after more exotic file types perhaps you might share the software you used.)
A calm sense of peace and serenity that you will get your files back... :fingers-crossed:
The Work
*****Based on the number of people having trouble with this step it is now my recommendation that you choose to recover your entire memory block instead of just the data partition. In my phone's case that is mmcblk0. Please discover if yours is different.
[*]*****For identifying which block/partition you want to recover, install DiskInfo from Playstore. Open the app and click on Data (USERDATA) to see the partition name for yours. For our purpose here we are seeking to recover the userdata partition: /dev/block/mmcblk0p21
Turn on your phone
Connect the phone in ADB mode
Unlock the screen.
Open a Cygwin terminal and enter (This assumes your BusyBox installation is at [/system/bin/busybox]. It may be at [/system/xbin/busybox]):
*Remember to enter codes line-by-line. After you enter su, you have to grant permission on your mobile phone at the same time
Code:
adb forward tcp:5555 tcp:5555
adb shell
su
/system/bin/busybox nc -l -p 5555 -e /system/bin/busybox dd if=/dev/block/mmcblk0p21
Open another Cygwin terminal and enter:
Code:
adb forward tcp:5555 tcp:5555
cd /samsung
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p21.raw
[*]Depending on the size of partition it may take a while to backup.
We need to convert the .RAW file to a virtual hard drive. VhdTool.exe basically just puts a VHD footer on the end of the .RAW file. Open a Windows command prompt, go to [c:\cygwin\samsung], and type:
Code:
VhdTool.exe /convert mmcblk0p21.raw
Now we need to mount the VHD in Windows. Select the Start button-->right-click Computer-->select Manage.
Select Storage-->Disk Management.
In the menu select Action-->Attach VHD.
For Location enter [c:\cygwin\samsung\mmcblk0p21.raw] and select the OK button.
Right-click on the name (e.g. "Disk 1") to the left of the Unallocated space and select Initialize Disk.
Select the GPT (GUID Partition Table) radio button and select the OK button.
Right-click on the Unallocated space and select New Simple Volume...
In the Wizard select Next>, leave the default for the volume size, select Next>, select a drive letter (e.g. K), select Next>, MAKE SURE to select the 'Do not format this volume' radio button, select Next>, select Finish.
A box will pop up asking you to format the drive. You DO NOT want to format the drive at this time.
Right-click on the RAW space and select Format... MAKE SURE to change the File system to FAT32. Set the Allocation unit size dropdown to 'Default.' MAKE SURE that the Perform a quick format checkbox is CHECKED. You do not want to overwrite the entire new drive with all zeroes (0's) and destroy your data. Quick Format means that it will only attempt to destroy the index for the drive by establishing a new index. Without this box checked the Windows operating system will write zeroes (0's) across the entire volume, potentially destroying your data. Select the OK button.
A box will pop up saying that Formatting this volume will erase all data on it. That would be doubly true if you actually didn't check the 'Perform a quick format' checkbox. Double check that you actually did check the box and select the OK button. (Don't worry. This essentially leaves the volume in the exact same state that your phone's internal memory is living in right now: there is data on the drive...you just can't see it. It's coming back, I promise!)
Open the Piriform Recuva application. In the wizard select the 'Next >' button. Select the 'Other' radio button and select Next >. Select the 'In a specific location' radio button and enter: k:\ (assuming K is the drive letter you chose...) Select the Next > button. Select the Enable Deep Scan checkbox. This is the magical setting that finds files that have been deleted...but not really deleted. Select the Start button.
The application may take about an hour to do the 'Deep Scan.' It's time for more laps around the house! Once the application has returned its results you can choose which files to recover using the checkboxes. Select the 'Recover...' button and choose the location to which you wish to output your files.

Profit! :victory:

You should add that the x86 version of Cygwin is needed, not the x64.

Do you also know that as of Android 4.3 this method doesn't work anymore?

yes

it works with 4.4.x and 5.1.1, it probably also works with 4.3. it's just an adb command after all.

No its not that. As of Android 4.3 Google enabled Trim on our decives. That means when you delete a file its really gone. Not even a professional company can get it back.
I have tried the above methode and I could not get any data back. Thats when I started reading about Google enabling Trim and found out its impossible to get it back.
Did you try it on Android 4.3+?

I have tried on my previous Samsung galaxy s3 (i9300) and my one plus one, both 64gb, i got at least 20% of the pictures back (.png, .jpg, ...), possibly even 50% since i had no idea how many i had on the device, some zip, most of .pdf and .doc and some other random stuff.
In both cases i did not manually delete the files from the phone, instead, i screwed up the partitions by deleting some system file, so after restarting, the SDcard/used data partition was empty.
i noticed though that even if my phone only had 500mb of free space available, the .raw partitions i extracted with this method were mostly empty, they only had about 10% of the data, so i guess some happened when android restarted, maybe yeah, some kind of trimming.
i think its worth trying anyway. just remember to not open any program or copy any file in the memory, as it would lower the chances to get anything back.

Yes but that's something different I think. Then you never deleted the files, they were there but not accessible.
If you look for example in the last 10 pages of the main thread, then no one is able to recover anything. Because it's simple not possible anymore. That's just how Trim works.

You should be honest with people. You should put in the op that it will only work on Android versions below 4.3. People are just getting false hope and wasting their time.

This is not my method nor I have, my self said that 100% you will get what you have deleted. I have only brought minor changes to the tutorial for the sake of successful transfer of data to the pc.
Now if you feel responsible for the feeling of people, definitely I will appreciate if you find another way.

That's the thing. You just copy paste a tutorial that does not work. Why would you do that? I can imagine that you did not know that it would not work anymore. But now you do know. What do you hope to achieve? Raising your thanks meter? You give people false hope and you waste their time.
And about me finding another way....There is not even a professional company that can do it. It's impossible at the moment.

I don't need thanks... why I should do.... it doesnt give me anything... I have got my own forum with its nice members.... if someone is in need of thanks, thats is you which is trying to show himself as a defender of others feeling, time, blah blah.......
I have recovered my file on a 4.4.2 android after a system crash which I had to reset the phone. if someone is in desperate need of something s/he will try anything and as far as I know trying this one doesn't harm anyone.
for you I have a recommendation, go and drink something cold and calm down!!!

Errr...

Awesome....the raw extraction worked on my S6 running Android 5.0.2. This time I tried it on a Mac and used Homebrew to install PV. Is there a way to get the entire image, even with the unused space?

Great
Thank you!
Worked on my sm-g900f
If you get nc/pv command not found , try this:
When you open cygwin terminal, start with this line: export PATH="/cygdrive/c/cygwin/bin";$PATH
The terminal should now know the location of them.
Same if you get that "adb: command not found" just type: export PATH=/cygdrive/c/XXXXX";$PATH
Just replace that XXXXX= to your location of adb.exe.
Hope it helps someone out of this ****

[Tool] SaveMyApp - Preinstall Your Apps

Tired of having to redownload and reinstall all of your apps when you reflash your phone? SaveMyApp can help.
This script will setup your phone so that after your flash to your favorite rom, all* of your apps will be install on the first boot. These apps will show up in the market too!
Also, the script will allow you to backup your /data/data folder to your sdcard and then restore it after your reflash. The /data/data is where Most of your user data is stored. This is not guaranteed to fully restore everything. This also does not backup your Google, Android, or Motorola settings; this is to improve compatibility with roms.
*The /preinstall folder is limited to 120MB, so if you have more then of apps this script will not fully work.
This should work with all phones, however it has only been tested on the Droid 2/X.
If you want to test this script on a different phone, let me know the /preinstall size and if it worked or not.

First!
I'm just holding a parking spot for this post!
What a great idea...thank you for developing this, im so tired of re downloading my apps back and setting everything up...done it about 10 times in the past month between sbfing and updating the fission rom several updates in a row so thank you...will most definitely be using this when I flash roms in the future. Thanks again

Excellent program! I'm having trouble getting it to work unfortunately. When apps.sh begins to copy files from /data/apps, I get errors saying "No space left on device" after every single file it tries to copy. This is of course not true since this D2 has over 6 gigs free on the system storage.
I am running this through the window's command prompt, but I don't see much in the code that won't run on windows aside from "du" which isn't even relevant unless my app + app-private folders combined size is over 120 MB (it's not).
I'm also running Epic 2.5 if that has anything to with this.
Any ideas? Am I just doing this terribly wrong?
Thanks!

If you read the first post it states the /preinstall folder can only hold only 120mb so it you have more than that to backup it won't fully work..I'm guessing that's were the apps are being saved...

Apps are normally saved in /data/app this script copies those apks to /preinstall so that after a wipe they will automatically be installed on the first boot. Yes /preinstall is limited to about 120MB.

How big is your /data/app folder?
OK! I sort of have it fixed. In that I'm not getting my original error.
What I did (which in retrospect was not such a hot idea) was delete the /preinstall/ folder and then created a new one with the subfolders /app/ and /md5/. The logic behind was that I saw the script had nothing in it to clean out the original preinstall folder, and I noticed that it had silly things like NFS in it. As I said, in retrospect I should have just deleted specific items from the folder, but that's what I get for acting without thinking too much.
How bad do you think it is that I remade the preinstall folder from scratch?
Now my preinstall folder is properly populated (I think). But the data won't back up for some reason. I think it might have something to do with the if statements being broken. I'm gonna go ahead and modify your script to bypass the if/else statements and see what happens.

The NFS removal is a good call, I will append the script to check the /preinstall folder and prompt to remove the files there
The reason you are having trouble with this script looks it be like because you are not running it on the phone itself...meaning to say you are not running it via a terminal emulator on the phone nor are you running it via adb shell. The backup uses tar, which isn't on windows by default.
Actually I'm running everything through the adb shell. It's puzzling to me too. My terminal emulator for some reason doesn't have root access. At this point I think I'm just going to SBF anyway.
At any rate, I just decided to pull /data/data/ from my phone onto my HD and I will replace it after I reflash and install my programs, but before I log into my google account. Do you see any reason for this not to work?

Hmmm, you might have to check your superuser app to see if you accidently are denying su access. In adb shell do you have a $ or a #?
Backing up the /data/data folder to your HD then restoring might not work because I am not sure if it will retain the owner, permissions, etc.
I had a # in my shell. There was something slightly wonky about my root I think. At any rate my backup method didn't work so well (as you predicted) - it caused timeriffic to force close when I tried to load in my old settings via /data/data/.
I will try using this again once I've got my shiny new Fission 2.1 set up as I want.
Thanks for your attentiveness!
I'm guessing this script should be run AFTER all of the applications have been installed. Is this correct?

install android SDK http://dl.google.com/android/android-sdk_r21-windows.zip and follow instructions to get the google usb drivers. Search XDA there are several guides, I couldn't find the one I used as of writing this article but there are many out there.
Search google and find a zip with just the ADB drivers.
Download Super One Click Root and use the drivers in the tools directory of the zip. http://forum.xda-developers.com/showthread.php?t=803682
Root Explorer - quick way to move and remount file systems rw with ease. I used v2.13.1. Google around and find an APK to install, just be careful there is another completely differnent package out there called "rooted explorer" it may work but I have not tried it. ** UPDATE ** I attached the version I used to this post
Google Apps for ICS - gapps-ics-20120429-signed.zip is what I used from http://goo.im/gapps/gapps-ics-20120429-signed.zip ** Update ** I replaced the URL with a direct download link from goo.im enjoy!
**NOTE** SUPER ONE CLICK ROOT WILL NOT ROOT YOUR TABLET SO DON'T BOTHER TRYING!
Step 2 install and configure your ADB USB Drivers (Let the fun begin)
Extract your zip file containing the ADB USB drivers or Install the Android SDK and follow instructions on how to use the SDK manager to download the lastest drivers from google.
Once downloaded edit the inf file (usually named android_winusb.inf)
Add the following under the [Google.NTx86] heading and again under the [Google.NTamd64] heading: (one is for 32bit systems and the other is for 64 bit Systems)
Code:
;ProScan plt-7035
%SingleAdbInterface% = USB_Install, USB\VID_2207&PID_0010
%CompositeAdbInterface% = USB_Install, USB\VID_2207&PID_0010&REV_0222&MI_01
After saving and exiting. Turn on USB Debugging on your tablet. It is under Settings => Developer Options and is the first option at the top make sure it has a check in the checkbox. Exit the developer screen by pressing back or the home key and plug in your tablet to a usb port on your computer using a micro-USB cable.
Device detection should at this point detect a few devices but at least 1 will fail without drivers. Possibly more on XP systems..
Under Device Manager => Other Devices you should have a device called "PLT7035-PL" use the usb drivers modifed above to install the ADB USB Drivers.
*** Important Note ***
At this point even with the ADB Driver installed ADB will not see the tablet. We have to create or edit the file c:\users\whatever your username is\.android\adb_usb.ini
If you have already run ADB at any time on your system the file and directory should already exist. If not you will need to create the directory and the file.
on a single line simply add this to a blank line in the file and save and exit:
0x2207
This tells ADB to look for that vendor code. (if you allready have ADB on your computer 'adb devices' should now show your tablet.
** UPDATE ** This is still necessary even if using the drivers attached to this post!​

Step 3 Root your Tablet!
*** Warning ***
I almost bricked my tablet on this step due to an error with a faulty PlayStore I had tried to install just using the APK. It kept the tablet from rebooting properly during the root process! I recommend erasing all user data before continuing YOU HAVE BEEN WARNED!
Click to expand...
Click to collapse
Extract Root with Restore by Bin4ry v15 to the directory of your choosing.
From explorer on your pc double click the RunMe.bat and select option one.
This particular root uses the system restore function to gain root access. If everything goes right you should get a prompt on the table to restore an image.
Click to expand...
Click to collapse
Press restore ON THE TABLET without entering a password or changing anything else and after a minute or two (maybe more) it should reboot.. Do some more stuff then reboot one more time and you should now have a rooted tablet.
Step 4 Copy root explorer and gapps-ics-20120429-signed.zip to the internal storage of the tablet.
Make sure the tablet is plugged into your computer and turn On USB Storage.
Copy rootexplorer.apk and gapps-ics-20120429-signed.zip to the Downloads folder via windows explorer and the removeable drive from the tablet.
Step 5 Install root explorer
ON THE TABLET: to applications => explorer => Internal memory => Download => rootexplorer.apk
This should bring up the apk installer and ask for permission to install rootexplorer. Follow the prompts until rootexplorer is installed.
Open root explorer. The first time you open it if everything is right you should get a prompt from SU to allow root access, hit grant. After that you might get a message that you need to close and reopen root explorer again, this is completely normal.
Step 6 Remount File Systems r/w
Once root explorer is open and has root access you should be in the root directory of the device.At the top you should see a message that says "Mounted as r/o" and a button to the right of it that says "mount as r/w".
Click to expand...
Click to collapse
Click the button to mount / as rw.
The message at the top should change to "mounted as r/w" and the button should change to "mount as r/o"
Click to expand...
Click to collapse
Scroll to the system folder and open it.
At the top you should see a message that says "Mounted as r/o" and a button to the right of it that says "mount as r/w".
Click to expand...
Click to collapse
Click the button to mount /system as rw.
The message at the top should change to "mounted as r/w" and the button should change to "mount as r/o"
Click to expand...
Click to collapse
Now click on the ../ Parent Folder icon on the top to go back to the root directory,
Step 7 Extract GAPPS
Scroll to and tap sdcard
Scroll to and tap Download
You should see the google apps file we copied earlier.
Click to expand...
Click to collapse
tap and hold on gapps-ics-20120429-signed.zip until the menu comes up and select "extract all" this will extract the zip file to /sdcard/extracted/gapps-ics-20120429-signed/
Step 8 Copy Google APPS to /system
Scroll to and TAP .. Parent folder at the top to go back a directory to /sdcard/
Scroll to and TAP extracted
Scroll to and TAP gapps-ics-20120429-signed
You should see 5 items, install-optional.sh, META-INF, optional, system and the ../ Parent Folder link.
Click to expand...
Click to collapse
*** WARNING *** Do not click on the install-optional.sh bad things might happen!
Click to expand...
Click to collapse
TAP and hold on the system folder until the menu comes up and select copy.
This will place a paste button on the bottom of the screen be careful not to hit it yet or you will have problems.
Click to expand...
Click to collapse
TAP ../ Parent Folder until the directory at the top says / (you should have to go back 2 or 3 folders)
You should now see a bunch of folders in the root directory as well as the tablets system folder. There should NOT be a ".. Parent folder" visible.
Click to expand...
Click to collapse
Now hit the paste button on the bottom left. You should get a warning massage saying "system already exist. Do you want to overwrite it?" hit yes
The file copy takes 1 to 2 minutes when it is done all that is left is to remount the / and /system folders r/o and reboot the tablet
Click to expand...
Click to collapse
Step 9 Remount file systems r/o
At the top you should see a message that says "Mounted as r/w" and a button to the right of it that says "mount as r/o".
Click to expand...
Click to collapse
Click the button to mount / as ro.
The message at the top should change to "mounted as r/o" and the button should change to "mount as r/w"
Click to expand...
Click to collapse
Scroll to and TAP system
At the top you should see a message that says "Mounted as r/w" and a button to the right of it that says "mount as r/o".
Click to expand...
Click to collapse
Click the button to mount /system as ro.
click the back icon on the bottom left until you have exited root explorer.
Press the power button on the top of the tablet and turn it off and back on.
If everything went right you should now have a fully functioning rooted tablet with Google Playstore...

Unfortunately as stated above there is no factory rom available for these tablets yet... I am looking into using rkflash or rkflashtool to download my rom prerooted so I have a backup and also can post a rooted rom for everyone. Most likely later this week I should have some time to figure out the rkflashtool and get it dumped.
I will post it here once it is done.
I'm going to say this now. I have a very busy schedule so I cannot guarantee when I will get this accomplished.
Also if this works for you please hit the thanks button.

Confused as heck !!
OK, I am confused as heck here. I have the SDK installed. I have the USB Drivers installed. The PC sees the phone just fine, I can browse the internal storage and the external sd card with no problem. Windows XP Device Manager shows Android Phone, and under that the Android Composite ADB Interface.
PDANet works with the phone, no problem. However, adb devices never shows the device, and the Root program cannot find it either. At this point, I'm stumped. Any ideas what I need to do? I have put the android_usb.ini file in c:\Documents and Settings\myusername\Android with the necessary hex codes for the device and for Google. I'm going nuts here!
I know ADB is installed properly, because I can plug my phone into the PC and run adb devices, and it's detected just fine. It's just this tablet it can't find.
FIX: Not as obvious as it might have been, but here is the solution to my problem. I used the Search function to find the adb_usb.inf file - umm... it's in .android, not android. Once I added those ids, everything was fine.
No Market?
Achieved root, copied over the system folder from the zip, but no market. Did I miss something?
What about Recovery?
Just wondering if there is a recovery option as yet? That would be so helpful!

Yeah, this happened to me too. And for some reason, when you go to the \system folder and look in apps there is another apps folder in there. I think there is something really odd going on with root manager possibly. I don't know what the deal is, but none of the Google Apps are running.
I've tried several older 4.0.x versions of GAPPS, and I will be danged if I can get any of them to work. I'm rooted OK, but that's all that worked thus far.
Good instructions! But failure... and then success
The instructions were great above! The pointer to the version of google play was bad, but I found this link http://forum.xda-developers.com/showthread.php?t=1934441 and after using Root explorer to do the appropriate permissions at / and /system, and on the renamed file, it works!
---------- Post added at 06:17 AM ---------- Previous post was at 06:06 AM ----------
Now that I got Google Play to work...
I am having an odd problem however - the installation of apps stalls at 0% for about 30 seconds, and then continues. And as the percentage is updated, I see app screens cycling. And little google play shopping bags start to stack up in my "task tray" area of the tablet.
Does anybody else have that problem? It's very annoying! It seems like the downloaded apps not only install but open, eating up precious memory.
Speaking of which, how is the flash memory used? (4 GB), and not having apps take up the 500 MB that's available?

It is 4GB shared. I haven't tried looking at the partition table.
There is only 2GB usable, it's on the TF card, I moved the apps there.
Not sure how to access the SD card to put apps there.

My GAPPS are working fine. I thought about killing that /system/system folder and manually placing the files via adb.
Try checking the permissions too, I think they need to be 644 or better.
I've put the Tablet away for now, I will tinker again later probably.

How do you move your apps there? I'm aware of the app called something like app2SD, but the TF card isn't an SD card.

You have to extract the zip file, remount the file systems as rw and copy the /system folder from the zip into the / of the device so that all the files goto their proper places... if you have /system/system it was not copied correctly...
as far as those not getting ADB to reconize the tablet.. a) make sure you have usb debugging turned on and b) you put the hardware id in the adb_usb.ini file.. See the ** important note ** in Step 2!
Unzipping Files
I have read and followed your directions to download the files, but, my unit keeps saying it can not open any zip files.
Do you have any idea why it may say this or how to get around this problem so I can continue as instructed?
unzip on your computer and transfer over, or use root explorer

You can unzip them on your computer and then transfer them over, or use root explorer on your tablet. You'll have to hold your finger on the .zip file for a few seconds and then the unzip option pops up.
Well, everyone be careful! When my Google Play would not install properly, I tried to clean the tablet up, ie, put it back to its original condition. Somehow, I managed to cause something to crash, and from then on, the tablet won't boot past the Android startup screen, although I can adb into it and it is still rooted, etc. What I've got now is a project tablet - HOW TO UNBRICK THE BRICK.

I hope you do so or some body find a way to unbrick this thing as for me i still have 26 days to return mine.i got to the part where I was about to paste the system I hit yes then everything locked up. I noticed before I hit yes it said do you want to merge and copy the files over not do you want to overwrite it but I still hit yes bad idea. can anybody tell me why I said merge and copy. well this is the second one I have bricks follow the steps perfect got all the way to the end and this is what happens so I took the first 1 back guess I'm going to take a second back also and try again until i figure out what I'm doing wrong.has anybody maked a rkimage or a .zip. update that will work to re cover this thing. I would be willing to try it out for you because I can.

try doing an ADB shell
then the following commands
su
wipe data
this will reset the user partition. I had something similar happen on mine.. BTW 'wipe all' will definitly brick your tablet so be carefull
If you still cannot get it I was almost in a car accident yesterday and my tablet went flying and broke the screen... If you confident with a soldering iron I now have a plt-7035 mainboard prerooted and playstore installed for sale for $25 including shipping.. it would involve soldering 6 wire and the wifi antenna if your up to it pm me,, I know its good as I was able to ADB into it and run su and wipe data to reset it..

[HELP] forensic file recovery from f2fs filesystem

The background: thought I had everything backed up but didn't realize there was something I missed. A quick wipe of all partitions on the phone has removed the data partition's file index. Then I realized I was missing data from my backup.
The problem: file recovery tools I've come across thus far don't seem to want to look for this particular type of file... simple XML. I'm also trying to limit use of the phone itself because installing of new apps to try and recover the data may overwrite sectors that are needed for the recovery. I'm already feeling sort of lucky that this is a 32GB internal memory device and my estimate of the file size is going to be <200MB. In that respect odds of data already having been overwritten in the minimal use I've had since should be slim, and if it has occurred it is probably something I can fake my way around.
Steps taken so far: from TWRP recovery's terminal I performed a dd of /dev/block/mmcblk0p38 (data partition on my Moto XT926M) to a file on an external card. This has enabled me to more easily work with the data from my Ubuntu desktop and also to not have to worry about further changes of the data from phone usage. I've already located via grep and parsed out via dd two XML files that I lost but those were easy as they were each under 100KB. I've located the start of the last XML file I want to recover but after about 1.5MB the trail goes cold. Either the data was contiguous and has already been overwritten at that point or the original file was being written, encountered a next block that was already occupied and continued writing elsewhere. I'm hoping for the latter.
SO...
With this image of the data partition and the knowledge of "this is where the file starts" does anyone have thoughts on how I can continue to work to find the missing pieces of this file? Assuming that from the staring point I've found that the original write just had to skip and continue writing at a different block, in f2fs is there a way to see that from the vicinity of the data I've located? I seem to think when looking at low-level data for some disk format method that the last handful of bytes (or maybe in some sort of header bytes?) of one file segment would indicate what block/sector/offset the next file segment would start but I don't know if that is the case here. Better yet any Linux based utilities that can take an f2fs partition dump and do advanced forensic recovery? I'm able to instruct it that the file starts at byte X of the image. I could try an Android app based solution but 1) that partition will continue to evolve and risk further destruction of desired data and 2) apps I've examined so far are great for finding pictures and videos, not so much at anything else.
My alternative is going to be to continue grepping through the image searching for known XML tags and manually trying to piece things together. At that point the 32GB MMC size changes from a blessing to a curse. Needle, meet haystack.
Oops, in hindsight I probably should have had this under "Android General" instead of this sub forum. Mods, I leave it to your discretion regarding movement but you can't argue that this is highly technical.
Any Luck

[HOW TO] Fully Backup & Restore Android Device

NOTE:
I'm not a developer or something even near to that. I'm a newbie and will be, seems so. All information provided here is copied and compiled from different internet sources. This information is according to best of my knowledge and comprehension and is just for curious souls like me who want to understand things in quite simple words.
I have tested this on different devices. I'll not be responsible for any harm to you or your device. It works perfectly for me. You may try it on your own risk.
Encrypted memory may cause problem in backing up and restoring data. So better decrypt it before proceeding. Or the Recovery should support decryption of /data partition.
WHY YOU NEED TO BACKUP YOUR DATA
For security, in case if device is lost. Read here more about the risks.
If you are going to change your device.
If your device is running out of memory space.
If your device is slowing down or giving random errors and you want a clean start i.e. by factory data reset.
If you are upgrading your Factory Firmware or ROM (OS).
If you are a curious soul like me and interested in experimenting with device.
WHAT TO BACKUP
Backup is a broad term used in many contexts.
PERSONAL DATA
On an android device, backing up personal data like pictures, music, videos, documents, e-books etc. means backing up Internal Memory (/data/media/) and SD card (if you use one). If you have disabled internal memory (D.I.M), your SD Card would be working as Internal Memory.
Personal data might be created by apps (like Camera, Facebook, WhatsApp etc) or imported from internet or other devices by yourself.
APPS & APPS DATA
If you are upgrading your ROM permanently, you might be interested in backing up your apps and their data as well. So that you don't lose important data and don't have to install apps again. System apps are stored in different folders under /system/ while user apps under /data/.
Apps typically store their data in /data/data/ but it's not a rule. Many apps save / backup their data on Internal Memory and/or SD Card as well. That's why you see folders named 'Android', 'data' etc. on Internal Memory and SD Card. Also, there are numerous folders named after app names. These folders may contain Personal Data as well, created by that certain app.
Contacts and messages are also stored in their default apps' data folder i.e. in /data/data/ and are not usually backed up manually.
OPERATING SYSTEM & APPS & APPS DATA
If you are going to install new ROM temporarily, you may want a complete backup so that you don't have to go through the hassle of installing apps and setting up / personalizing your device again. It usually includes /system, /boot and /data partitions.
OS consists of SYSTEM and BOOT. While user apps & apps data is stored in DATA.
PARTITION IMAGES
From a developer's perspective, one may want to backup the whole device partitions, in case if something goes wrong during experimenting.
Read here more about android partitions.
WHERE TO BACKUP
INTERNAL MEMORY (/sdcard) (/storage/sdcard0) (/data/media/0)
This memory can be used to save data if you are not going to wipe / clean it. A Factory Data Reset usually doesn't wipe this but it can. It depends on the device. Similarly, Recoveries usually don't wipe internal memory but you can manually do so. However, formatting /data would certainly erase internal memory. Formatting might be a part of flashable zip if you are going to install new ROM. Flashing Factory Firmware using flasher will also erase internal memory.
EXTERNAL SD CARD (/external_sd) (/storage/sdcard1)
This is a more safer place to save / backup data because it is not wiped unless done manually or accidentally.
PERSONAL COMPUTER (USB Flash drive or Internal / External Hard Disk)
This is the safest place to keep data with abundant space and the least chances of losing / corrupting data.
ONLINE / CLOUD STORAGE
Some apps, including Google offer backing up your data online and auto-synchronizes it. You should certainly avail this option particularly for sensitive and light weight data like contacts, messages, documents, saved passwords, bookmarks, financial transactions etc. WhatsApp also has a good online backup option. You can use apps like Drive, SMS Backup & Restore, FolderSync, KeepSafe etc. to better utilize this option. But technically, this is a limited option.
HOW TO BACKUP
FILE EXPLORER APPS
You can use a file explorer like ES Explorer or Solid Explorer to manually copy files from, say, Internal Memory to SD Card to back it up.
BACKUP APPS
Some default apps have built-in feature to backup data and settings locally and online e.g. GO-SMS, Tasker etc. You can check apps for this feature.
Also, special backup apps like Titanium Backup can backup almost all of your user and system apps and their data. It can also backup contacts, messages, device settings etc. It can create a flashable zip of backed up data to flash through recovery. However, backups from one ROM may not fully work with other ROM's.
CUSTOM RECOVERY
Backing up data when ROM is running isn't safe. When files are being used by OS, they might not be written / read sometimes. So, a custom recovery is the best option to backup/restore data. Custom recoveries (TWRP/CWM) can backup / restore partitions SYSTEM, BOOT and DATA (excluding internal memory) for sure. Some new recoveries offer backing up more (or all) partitions on device. You can choose where to save backup files i.e. Internal Memory or SD Card. Then you can transfer these files to PC as well.
You can also use recovery's File Explorer to copy Internal Memory to SD Card. However, it's a slower process if you have a large number of files to backup.
PC
You can use PC in multiple ways to backup/restore data within device or from/to PC.
First of all, you will often come across different software advertised on net claiming to fully backup your device when connected to PC. They work but are not much useful / reliable according to my experience. Give them a try, if you want to.
Secondly, you can use USB cable to directly connect your device (as MTP in ROM or recovery) to PC or use apps like Wi-Fi File Transfer to wirelessly connect (in ROM) and then explore Internal Memory and SD Card. FTP or SFTP (SSH) server may also be setup on Android to remotely access it from PC if both are on same network.
Thirdly, you can mount SD Card as flash drive (UMS in ROM) or switch off your device, remove SD Card and then insert directly into PC through card reader to manually copy files. This method is faster, to copy large data. However, mounting as UMS in running ROM isn't recommended, particularly if you are using D.I.M. It will crash apps.
In Android 5+ UMS may not be available in USB settings as it has been deprecated in favor of MTP to avoid problems. However, to copy large data from internal SD card is really problematic without direct USB connection. Or what if we need to recover accidentally deleted data from internal memory? We can directly attach internal memory (as in UMS) to PC by a little hacking.
Fourthly and ultimately, like a boss , you can use life saving ADB feature of android to backup/restore your data as well as recovering your device from difficult situations and doing a lot of stuff. It's the best and fastest method to backup Internal Memory to SD Card and then restore (COPY WHOLE FOLDER (within device)). Or you can COPY WHOLE FOLDER (From/To PC) or COPY WHOLE PARTITION IMAGE (within device) or BACKUP / RESTORE APPS & DATA (From/To PC) in seconds.

Another application that you can use to backup your phone to computer is Apowersoft Phone Manager. This works greatly in managing your devices plus it make sure that all your files are secured from being corrupted or loss.

I can't determine the efficiency of the Apowersoft tool, but if you want to backup data , this is right way , after the phone data is backuped ,you don't have to worry about the deleted data unable be recovered back ,
The backup files is the best way to recover deleted data from phone
Kindly guide me on restoring app data alone from a nandroid to newer version of an app..
The scenario is that ,I upgraded to a higher android OS but find some of my apps(with no cloud storage),restored from my nandroid ,crashing; probably prompted by the change in OS.
I downloaded the compatible version of the app from playstore,but am clueless how to sync restored app data from nandroid to this version.

Would you please mention apps names? Don't uninstall previous version. Just install compatible version over it. It should automatically have previous app data.
The backup program is much simpler than the android recovery program,
I came here looking for the best way to back up my internal storage before activities like flashing a new ROM or firmware. Previously, I'd plug my phone into my PC and just drag and drop the internal storage partition to a folder on my computer, but I'd often have to do it a few times because some file would get hung up, or the phone would randomly disconnect (even though my phone, cables, and computer are all new and high quality).
I'm currently using the TWRP file explorer to copy /sdcard to /external-sd/!InternalBackup, but there is no running log or progress indicator... So, this approach is less than ideal.
I'm still looking for the best method (not necessarily a software that will do it for me) that will do it fast, not get interrupted, and provide good feedback on if it's working and how much longer it will take. (The TWRP method above checks the first 2 criteria, but the 3rd is woefully insufficient.
I'm thinking that the best way to back up the internal SD will be in recovery, otherwise something might be in use and will halt the process.
Any suggestions?

Commandline solutions are always best. You have better control over them. Use TWRP built-in terminal to run commands.
Simply 'cp' with verbose option "-v" is what fulfills your needs. 'rsync' is better if you want to save time by automatically skipping unchanged existing files. If you want to preserve file attributes and permissions, use 'tar'. Added compression can be achieved by 'xz' or '7za'. All of these commands are stable solutions, with high speed and ability to handle/resume broken/interrupted operations.
TWRP comes with busybox bundled. Busybox utilities have limited functionality and mostly suffice the need but rarely we face unexpected behavior. Instead you can use full static binaries of these commands.
Typing lengthy commands in TWRP shell terminal is somewhat challenging. Either use 'adb shell' or for repeated use, create a shell script and place it in internal memory or SD card. Or you can unpack TWRP image and save script in /sbin directly to run it just as a normal command. Another easy way is to create a flashable zip of your script. This way you can also see progress bar moving if you write a proper script for it.
Hope it helped.

That's a lot of help... But I lack the basic understanding and experience to make use of it all. I'll have to Google it a bit and look at some examples. Thanks!
UPDATE: I did a little research, and I succeeded in using "cp" to do a test move in TWRP (I had to use -r and -v), but even using -v didn't create a progress bar or any indication that files were being moved. It just finished and went to the next new line. Is this expected?
Also... my version of TWRP doesn't seem to have rsync available. When I try to use rsync in TWRP, I get
Code:
sh: rsync: not found
So it seems that TWRP's terminal doesn't have rsync. I'm using TWRP 3.0.2-1
So... I'm currently using the Termux app to do the cp operation. I'd prefer to use rsync, which is supported in Termux, however, unless I do "su" first, it says it doesn't have access to the destination folder. And, when I use "su" I can't use rsync. I get pretty much the same message as when I try to use it in TWRP... something like "rsync not found"
Does this mean that when Termux is using root, it can't use rsync? Does that make sense?
Any help?
Thanks!

'cp -r' copies recursively i.e. files/directories under directories and so on. So it's definitely required if you want to copy directories. 'cp -v' shows each file which is being copied, but not the progress during a single file copying. Check 'cp --help' for options.

TWRP uses busybox which doesn't have rsync built-in. You can get a copy of static (independently working) rsync binary from many sources like this. Aarch64 will be a bit faster. Check 'getrpop | grep ro.product.cpu' to find your CPU architecture if it's 64-bit or 32. When in TWRP, place binary in /sbin directory. Then do 'chmod 0777 /sbin/rsync' to make it executable. Now you can use rsync. 'rsync --help' will show you options and basic help. Do note, /sbin is on volatile filesystem i.e. it will be gone on reboot. Don't expect it to be permanently there. You can also use rsync from other locations like sd card but that will need to call binary with full path and filesystem may put restrictions on execution.
So... I'm currently using the Termux app to do the cp operation. I'd prefer to use rsync, which is supported in Termux, however, unless I do "su" first, it says it doesn't have access to the destination folder. And, when I use "su" I can't use rsync.

It's expected. When we do 'su' on Termux, it's environment is gone and PATH is set to /system/bin etc. So any binaries which Termux downloaded to /data/data/com.termux/files/usr/bin won't work. There are better options, but easiest is to use 'tsu' instead of 'su' on Termux. It will handle things for you to run Termux binaries in superuser mode. Do 'apt install tsu' when connected to internet. Once installed, simply execute 'tsu'. Now you can use Termux rsync binary.
Or use rsync static bianry instead as explained above. Copy rsync to /system/bin/ or /system/xbin/ etc. and set permissions. SELinux may interfere if it's set to "Enforcing". Do 'getenforce' to check and 'setenforce 0' to set it "Permissive".

This reply is probably a bit late for you, but...
If you install tsu (pkg install tsu) in TermUX and use tsu rather than su, it'll work.
Tsu sets up the runtime context for su properly.

Hey, it's never too late to refine your backup strategy. Thanks for letting me know.

Am I doing something wrong? To be clear.. I just did "rsync" without any commands/switches to see if it would produce the help info. I knew it wouldn't actually attempt to copy anything.

Lol! You missed the key point: use tsu instead of su.
Instead of typing "su", type "tsu".
But don't take it too hard - I did the same thing when I first started.

/data/data/com.termux/files/bin/tsu is just a wrapper i.e. a shell script that sets environment variables for Termux and then executes 'su'.

Is backup feasible when sd external card has been mounted extending the internal storage (Android 6.0), working as internal storage as well?
Can some expert comment on this, just not to go crazy for nothing. I don't want to upgrade with last rom by manufacturer and lose my data.
I have ADB , fastboot and usb drivers, but trying and use Helium backup I was unable to pair, even though the phone is connected (I can select onscreen for instance PTP or usb storage, tried both, nothing).
Not even sure about nandroid backup also.

Yes it's feasible but depends on what, how and where you want to backup.

Any solution is fine to me, I just want to be able to restore apps and launcher (Nova launcher prime) with icons arranged as they are, without having to start all over from scratch.
Other data are on the cloud, so if I can possibly backup some folder (from phone or sd card, if the difference matter in my case) good, or I'll take care of it in advance.
Just having the phone upgraded but not reset from the beginning.
If necessary I can try rooting it. Thx for replying.
how to use a twrp data backup for oder rom?

Backing Up to External SD Using TWRP Command Line and No Display

I've spent the last couple days searching around to fix this problem, not only on XDA and Google, but in TWRP's Issues and code on GitHub; all to no avail. So here it is:
I have a device with a broken display. The only way I can initiate commands on it are with the power, volume, and home buttons, and with adb. I've installed TWRP on it, and I'm able to boot into it. I'm trying to back up everything on the device I can to a 32GB external SD card in the device's SD card slot. But when I keep getting the following result:
Code:
~ # twrp backup SDBOM
Setting backup options:
System
Data
Boot
Compression is on
Digest Generation is off
Updating partition details...
...done
* Total number of partitions to back up: 3
* Total size of all data: 7976MB
* Available space: 496MB
Not enough free space on storage.
Backup Failed
Done processing script file
The External SD Card has more than enough space for the backup (several times over, in fact), so clearly TWRP is attempting to save the backup to the device's internal storage. It seems, from testing I've done on an identical device with a working display, that twrp backup in the command line saves to the Storage last selected in the graphical version, but since my device's display is broken I can't select the External SD Card as the storage for the backup.
Since I have no display, I also can't do adb backup --twrp, since that requires confirmation on the screen.
Is there any way to select the storage for twrp backup fully through the terminal? For example, is there an environment variable I can set, or something I can pass twrp backup?
I figure this is an easy one to answer, and that it's something really, obviously, simple (so much so that I'll have to hang my head and never show my face here again!). But for the life of me, I can't find it.
Same thing here. In my case I have a working display but my kernel does not allow any touchscreen operations when in recovery so I can see TWRP but not input anything. So the command line is my only way to use TWRP but like you I cannot switch to creating backups to my external SD card.
It seems funny there is no solution to this since having touch screen problems with TWRP seems to be a common issue so how do all those folks with no touch recoveries do their backups?
check to which folder mount yours external SD
and set var "tw_storage_path" with "twrp set"
example "twrp set tw_storage_path /external_sd"
you can find this var in android_bootable_recovery/openrecoveryscript.cpp
also
you can change backup folder
example "twrp set tw_backups_folder /external_sd/all"
can find it in android_bootable_recovery/variables.h

Hello and thank you very much for helping on this issue.
I gave up on this long ago but it is still of great interest to me since I am still using the same phone and TWRP backup would be welcome. But since so much time has passed since I unpacked the recovery, I am a bit rusty at it. I am an old programmer but my android knowledge is limited, still I did succeed to make the sdcard visible to the recovery (cant remember how but I think I changed its block name in recovery.fstab then for some other reason also had to un-repack) so I can handle such things if I am guided a bit.
So your help is very welcome and also reignited my interest to solve this issue. Problem is I cannot find the "android_bootable_recovery/openrecoveryscript.cpp" script in the unpacked recovery or the phone's file system. I am sure I am missing something silly but googling around did not help me either.
Could you possibly guide me into finding those scripts so I can edit the aforementioned variables?
Thank you very much for your attention and help.
Chris.

Hi again.
Okay now I understand, I will download from there and check what I can come up with. I already feel that this will involve some compiling and I wonder how that is going to affect my custom TWRP (which I found at twrp builder). I will step into it and see.
Thanks a lot for your prompt help, I really appreciate.

Sorry if i misunderstand you but why compiling? You dont need it. You can change this vars from adb terminal. Boot device into TWRP connect USB to PC run adb shell and you can change vars in shell via commands like this: 'twrp set tw_storage_path /external_sd' and so on.

Oops, I thought I had to change the variable in the source files and then compile the recovery from scratch. This is now great news I will check it tonight.
Thank you again!
EDIT: For anyone who has the same problem I confirm that I checked it and the method above works fine! Kudos to you OrBitRo!
