How to unencrypt backed up disk image - Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)

Recently I tried to flash root on my phone and I corrupted the ROM. I couldn't boot so I backed up an image of the disk, saved it on my pc and then recovered my phone. I have the disk image, and I'd like to unencrypt it to recover some things I had on my phone. Is it possible to unencrypt the image on my computer?

Can you explain every steps?? I mean how did you corrupt the Rom while rooting???
Most of the times The Backup can be restored easily and phone works fine. But in your case *Disk image , i am unable to understand what you are talking about???? Are you referring to system image??

I flashed supersu to get root but the system woudln't boot. I ran adb pull on the data partition and backed it up to my pc. After that I formatted the disk and reinstalled the os, so I dont have the data on my phone anymore, only on my computer on a .img file. I want to know if you can decrypt that file and get the original data.

Deleted internal storage in TWRP. Need Help.

I deleted the internal storage on my phone in twrp. What can I do to get everything back?
I think you're boned. Unless there is a way to pull the deleted data using software on a PC.
Fastboot factory IMG. Or use rom tool kit to flash a factory image. There is an option in twrp to connect to the PC where you can transfer files. You could always load a rom that way and flash a zip through twrp
As said above, you can still install a ROM. Or flash a factory image etc. But the data (pictures, videos, music etc) is gone. It was formatted and not likely able to be recovered. I assumed that's what you meant, when you asked to "Get everything back"?
My sad sad self went and did this. Still in TWRP. I've mounted system, data, and cache. I see the Nexus 6 in Windows 7 and see Internal Storage; it's empty. I cannot create new folders or copy files (ROMs, GApps, zips, etc) into Internal Storage without getting "The device has either stopped responding or has been disconnected." I cannot for the life of me find another way to push files to the phone.. Any help is greatly appreciated!

EDIT: Is it still possible for me to follow Mr. Hoax's Tut through bootloader? (I'm really nervous to try and reboot into BL) It says I don't have an OS (obviously) when I get to the confirm reboot of TWRP...

You're referring to TWRP, correct? Wipe->Format Data? I have done this but am unsure how to proceed... I still cannot seem to get files to copy onto Internal Storage...
EDIT: I got a ROM, GApps and SU to stick to Storage!!! Gonna try to install now.
SUCCESSSSSSSSSS!!!! WOOOOOO! Totally gonna try to update to 5.1 again haha Thank you thank you thank you @simms22!

Tip: it will not allow to format user data right after deletion!
You will need to restart recovery and only after that it will format the user data!

Is it possible to mount data partition on PC or USB to recover data

Is it possible to mount data partition on PC or USB to recover data?
Edit: I meant userdata partition
I have tried backing up data partition using TWRP, but it prompted me that pictures and downloads will not be backed-up!
Isn't the data partition that holds my camera and download folder?
I am looking for a tool or and app that can let me take a disk image of internal SD partition, or create a whole image of my phone; so that I can use data recovery in my PC.
Making Dump Files Out of Android Device Partitions
have u try this
Thanks I have tried it but when I execute
Code:
noblelte:/ # dd if=/dev/block/sda17 of=/sda17.img
Gives me
Code:
dd: /sda17.img: Read-only file system
Just to be sure : I ran the adb code while the phone is on normally not in TWRP.
I also ran the code in TWRP terminal, while connecting a USB and mounting it.
It created the image inside the USB , however it stopped at 4GB saying the file is too large.

Are you just wanting to back up pictures, download folder, etc etc? Backing up the data partition the way you are is pointless as you're just accomplishing what twrp already does. Data partition is apps, system configurations, texts, calls, etc. Not pictures you've taking, download folder, etc.
And is there a reason you want an img file? Seems pointless to me when you can just copy it all over by drag and drop or adb pull the internal storage lol
I want to make a userdata partition image because it holds the camera album I deleted by mistake. I want to take the image and try to recover the deleted files using PC recovery software.
I found out that my problem was the 4GB limit of FAT32, so I formatted my USB flash memory using both exFat and ext4 and recovered the partition using TWRP terminal with the code above.
However I am still unable to read the image through Linux Reader and I can't attach the image as VHD.
Is what I am doing is useless? Because it came to my mind that if the recovered userdata partition is encrypted I will not be able to opened it, however, TWRP can browse the files so I guess it is not encrypted.

You may need to convert the file type of the img using simg2img, make_ext4fs, etc
You can see what the file system type of the img you have by running:
file blahblah.img
But still don't think you're going to recover them but possibly lol never tried as I sync everything to a cloud

For backing up app data, I'm more of a Titanium Backup person myself and for backing up partitions I generally prefer TWRP, but there are also apps for backing up all the different partitions as well. This is just one. Never tried it, but Wanam is a much trusted developer in the XDA community for Samsung devices.
https://play.google.com/store/apps/details?id=ma.wanam.partitions
NOTE: You can always save these backups to a USB OTG device if you need to as well. That's what I do with my Titanium Backup app data files and the information is with me all the time hanging on my key chain.(More info about that under "No SD Card Slot" on this post HERE.) This information can of course always be copied to a PC too.

The only thing that will take your fear, is a backup of all important partitions (boot, system, data, vendor, efs, persist), stored externally, plus a copy of the internal storage content, also stored externally.
With that you should be able to restore everything to the exact point it is at right now, so you'll really need to mess up hard to not come out of basically any situation with those partitions saved.
As for your inital question:
Why don't you just update via ota if you wanna stay on stock?

Okay, so maybe first copying internal storage content to your PC and backup important apps would be sufficient then.
For apps you can use Titanium Backup (good, but makes troubles on android 10 at the moment), Swift Backup (recommend by many others) and more.
These backup solutions save apps and app data on your phone, so copy that to an external place, or you might lose them if you need to format data (which I'll suggest).
After your "backups" are made, I would wipe every partition in each slot, which you can also achieve with a "fastboot -w", and then also format data - the one where you need to type "yes" (which will also erase all internal storage content, but most probably will also solve your troubles).
From here there are tools like miflash or fastboot images to reflash stock (inform yourself about them, before you start all that!).
Be sure to flash the latest one right away, so you won't be in the need of "dirty" updates immediately again.
Afterwards, you can copy back the internal storage content and the folder of the backup app, and restore the previously saved apps.

I tried MiFlash, but without wipe anything, and it don`t upgrade version of system
But if I must, flash 2 slots A/B using MiFlash or one slot (A) is for system?
You can just download the zip file with version u want from the site below and flash it via TWRP making cache and dalvik cache wipes and changing slots at the end.

Just if u want. It's not necessary.
In october I updated mine this way but forgot to change the slot before rebooting to the system and realized that was in the old Android version. I just went to TWRP again and changed slot. After rebooting, the phone was in the updated Android One.

Soft bricked phone after trying to restore backup after LineageOS flash

I flashed the lineageOS 17 roms that is available and it worked but then i realized that gapps was not complete so i went into TWRP to restore my old Backup of ColorOS 6.1 (A.08 version), also it had magisk installed, but it then would show the first boot logo then restart and go into the recovery. I then tried formating everything except internal storage and also factory wipe and now my backup is gone and everything else on my phone. I can still boot into recovery and such but now it wont even ask me for the decryption password. File manager in TWRP shows 3 folders in the internal storage (in sdcard 0, obb and TWRP).
Any help? i dont wont to break things even more.
Edit: I just noticed that in the 0 folder in sdcard there is 65 gb of folders and files. Im assuming that are my old files but they are encrypted. Any way to undo that?
I guess you have to install a rom and set everything up from scratch. You lost all your files when you formated data, including backups, etc.
If you want to update or change your recovery, now it's the time - since there's no rom or files to lost.

I didnt format the internal storage only data and i edited the post saying that i think i found all the data but still encrypted. Im guessing TWRP wont automatically decrypt it.
For anyone with a similar problem. I reinstalled LineageOS and it decrypted all the files.

How to recover my files after failed supersu flash?

Today I wanted to root my phone. So I flashed twrp to later flash supersu. After i flashed twrp the phone worked fine, I could boot normally and go into recovery to access twrp. However, after I flashed supersu I couldn't boot back into android. After several tries of recovering the data its been a mix between bootlooping twrp or being stuck in the splash screen. I could format the partitions to clean everything, but I can't do that because I need to recover my 2FA codes (cause I didn't backup them up) so I dont lose access to my accounts. I tried unencrypting the storage from twrp but it always failed, even though it was the correct password (I use a pattern to unlock but I converted it to a code). Is there any way I can recover my data or do I have to reset everything?
