Device: SM-G532G Galaxy J2 Prime
OS: 6.0
What Happened:
I tried to root using a CF-AUTO-ROOT image and Odin and got stuck in a boot loop. Then i tried few other stock Roms (<20MB in size each of them) got it working/boot somehow. But all my user data is missing now.
Problem:
Device used to have 8GB Rom with around 2.5-3.0GB free space before this. But now it shows only 1.44GB when i check storage on PC. and shows 7.84GB as system/user data in system storage menu.
Desired Solution:
I need to access my previous user data (specially SMS). That's all.
(So factory reset and wiping which are the common fixes for this are out. )
What I have tried so far
1. TWRP - installed TWRP and tried rooting. (cannot view the zip file as it shows cannot mount /data error in log)
2. Trying with ADB to view (at least) the user data but had no luck. (may be i might be missing some step and ROOT of course)
is this something like i have manged install 2 OSs on the phone somehow (like dual boot without the correct bootloader) or some thing else?
Any help/guide is much appreciated. Thanks.

Hi guys,
I'm just going through the rooting process on here using the latest guide and I'm just getting the usually (which I've seen lots of people ask):
E: Can't mount sdcard
Now is this down to that I've selected in Location and security to setup the pre-boot encryption (Encrypt Drive) ??? Cause surely once you have run WDE (whole disc encryption) then the device cant be root'ed too?
Is this the case or is there another cause?
Cheers,

Greetings, Antz-
That's been my experience, experimenting with a Samsung Galaxy Tab 10.1.
It would stand to reason that if the rooting process intends / attempts to modify system files and packages, without first completing the preboot authentication to access the decryption key - the attempts seem to fail (sometimes benignly, sometimes with undesired results).
It depends on both the type of encryption - but assuming full device encryption, and noting that the CWM, ODIN, etc do not prompt for the device password - I think it's a correct observation to state that these devices can't (easily) be rooted.
I think it should be possible if you're willing to backup (manual or automated), restore to factory defaults, root, restore backup, and then re-encrypt?
Please bare with me since I am still learning about android and so my question is, how can I recover my applications from my tablet after I have rooted it.
I flashed cyanogen 9 to my SGT2.10.1 and it was successful, although I am stuck on trying to recover my applications from the partition internal memory. Of course I have done a variety of steps to recover them and some of the steps I took are:
1. I tried using the spk tool - I really do not know how to use it and I am having a hard time figuring it out
2. Trying to delete and reformat the internal memory - was not successful since it only erased of what I currently had on the rooted and partitioned memory, thus my original application are still within the internal memory.
3. I tried using applications such PC36IMG-AmonRA-3.07-gnm.zip - I changed the name to PC36IMG but flashing it lead to installation fail/aborted
4. I tried recovering them with titanium back up - but the application couldn't see my original applications
5. Also tried using Astro File manager - Same results as TBU
6. Deleting the files from my pc via usb- it does not give me an option to reformat it
Any suggestions? this is the final step that I need to complete to finally enjoy my retarded galaxy tab 2
Hello everyone,
I need your help. Sorry for the long post.
I have a OnePlus One. It was running on CM 13.0 (Android 6.0.1). I had TWRP and MultiROM installed.
I have had an issue where whenever I flash a zip file in TWRP, the phone will show an error after installing the zip: "Unable to mount storage". This appeared in red color on the screen right after showing the progress of the zip installation. The phone worked fine and all the flashed zips worked great as well. However, the error that appeared every single time when I flash a zip file bothered me. So I tried to fix it. (I know, if it's not broken don't fix it, but sadly I tired).
I followed this video to get rid of the error => (https://www.youtube.com/watch?v=X7yDPszoQ5s). However, instead of getting rid of the error, I ended up with a huge problem. My phone couldn't recognize the data in the internal storage. It showed that the internal storage was empty. When I tired to reboot in TWRP, It said: "No OS installed are you sure you wish to reboot". I realized that the video I followed was for a different problem and that I ended up with the same issue the video was trying to fix! I tried every single option the video suggested to fix the problem and nothing helped.
I connected my phone to my laptop and downloaded the latest CyanogenMod zip for my phone and I flashed it. when I rebooted my phone I got a screen that asked for my password. I typed a random password (I discovered later that the phone will accept any password and say it's correct). I got the following error: "Decryption Unsuccessful... The password you entered is correct, but unfortunately your data is corrupt... To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your google account...Then the only thing I can select is "reset phone." ". I pressed the reset button on the screen, the phone rebooted and showed the same error. Then I tired flashing PAC ROM and I got the same error again. Then I flashed OmniROM and the phone worked! It didn't show the error.
I have a Titanium backup for all my apps and I also have a nandroid backup for my previous ROM (in my memory stick using an OTG cable). However, I don't have any backups for my internal storage (photos, videos, documents... etc). I am guessing that these files are still in my internal storage. I didn't copy any new files to my phone because I think if I do, then the phone will keep replacing my old files (that I can't see) with the new ones.
My question is: Is there a way to get back these old photos and videos from the internal storage? Note that I didn't delete these files, but the phone can't read them. Also, I checked the nandroid backup that I have and the file system type of the previous ROM was EXT4. My current file system type is the same, EXT4.
Thank you for the help!
My galaxy S2 (gt-i9100) was running cm13 for about half a year. Some days ago I let google play update my apps. The result is a bootloop.
I've used the voice recorder to record a lot of notes I need to remember. Is there any way to get those files out from the phones internal storage?
The CWM recovery installed lacks the option to wipe cache / dalvik, which I would hope could get the device out of the bootloop.
When booted into recovery, I've tried adb, but the device is unauthorized.
I think usb debuging was disabled, however, I'm not sure about that.
The ideas I have to solve this are:
1) flash some other recovery that will give an option to wipe cache/dalvik and be able to boot cm13
2) flash some other recovery that will make adb able to pull the files while in recovery mode
3) flash some recovery that is able to copy files from internal storage to sd card
4) factory reset, and hope the files don't get deleted (this is the very last resort)
The thing is that it seems like I'll need to do all installations from SD card via the current CWM recovery. Does anyone know of a suitabel download / howto that can help me get my files off the phone?
If reason for boot loop is Xplore file explorer latest update , uninstall it with developer advices:
http://www.lonelycatgames.com/wiki/xplore/crash_on_cm
I did factory reset twice because of app.
Thank you, Kepsilla. Unless that is an app that is installed with cm13 or gapps, I don't have it installed. But your link gave me hope:
If you have custom recovery on your device (such as TWRP), enter recovery mode, open file manager and delete folder /data/app/com.lonelycatgames.Xplore-1
Click to expand...
Click to collapse
That means that if I can install TWRP recovery from CWM recovery, I should be able to access the filesystem. That should open up to two possible solutions:
a) Copy my files from internal storage to SD
b) Delete / modify some files to take all apps I've installed from play store will not start automatically.
Does anyone know of a TWRP that would give any of these possibilities and install on a i9100 using CWM?
(I can't really experiment iwht this - I feel the risk of loosing the files is too high. I have to know I'm going the right direction when I do something.)
Solution was very simple: By holding volume down pressed during boot, the device boots into safe mode - no apps started. Then I could just uninstall the apps that were set to autostart. Reboot and problem was solved.
I came across this way to enter safe mode when googling a error message that started to pop up frequently on my S5 mini. S2 with cm13 appears to have the same way to enter safe mode as S5 mini with factory rom.
I´ve tried to find any specific info on the subject for this phone but found none.
Maybe someone can help.
All was good on my phone when using Havoc custom rom. Yesterday I tested an android 11 custom rom on the device but decided to go back to 10. Orange Fox recovery restore gets stuck in the boot process. When using TWRP it can´t acess Data partition, so I´m unable to make any backups of data partition with it.
I´ve tried two diferent versions of either, and on TWRP after formating data the partition is once again acessible, but as soon as I flash a custom rom (tried two diferent one´s), boot to it and then reboot to recovery the Data partition is once again unacessible (encrypted) showing "0 MB".
Orange Fox recovery allows to access the data partition and so allows for backups to be created, but the restore process always ends up suck at boot (odly enough when enabling MTP on Orange Fox and connecting the phone to my Windows 10 machine two internal storage partitions appear in Explorer along side the SDCard one - all with the same content exactly). Something weird is going on here.
I´ve tried the steps on this post regarding DM verify (I do not know if it has got something to do with it) but it did not work (the fstab file already shows decryption on its entries):
[Deprecated] Universal DM-Verity, ForceEncrypt, Disk Quota Disabler [11/2/2020]
Hi all! For the past couple of months, I've been looking into making a more universal solution to disable dm-verity and forceencrypt. Needing to take different zips, modify them for different devices, and then cross your fingers when you switch...
forum.xda-developers.com
Has anyone had similar problems or knows what might be going on on my device?
Is the internal flash memory going bad maybe? I´m at a dead end here.
Apreciate any idea.
Thank you.
