Hey, so I rooted my Galaxy S7 edge exynos, and everything was great. However, when I boot into recovery, TWRP can't do anything. It can't backup, install images, nothing. It says my memory is 0mb, and if I try to backup it says "cannot mount /data and unable to find crypto footer". I can restart my phone to system and everything works perfectly. Is there a way to fix this? I'm using latest version of TWRP (3.0.2)
Thanks guys!

FORMAT DATA, it's explicitly stated in the instructions. You must format data to wipe encryption.

Is there no way around this at all? It's really a hassle having to reset my phone every time.
Is there at least a way to install xposed without formatting?
Thanks!

You only do this once, use flashfire or titanium backup to backup your stuff.
did you flash this after TWRP?
"If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer no-verity-opt-encrypt.zip to your device over MTP* and flash it using [Install] in TWRP."

same here !:<
Same problem a few days ago. Caused by secure startup or encrypt device obviously lol. Only fix for read/write on data/internal storage is factory reset in stock recovery. Unfortunately this was the only fix for my fussy G935F.
TWRP couldn't mount data to wipe anyway I tried and the only way to flash was through selecting extSD.
i dont have escription enabled though ._.

I find a solution, just go in wipe and format data , it will removes encryption on internal storage. if not works try a factory reset in stock recovery them try again, S7 is encrypted out of the box and Twrp can't read or mount data. Works for me in G935F.
how long does it take to format? i chose exfat and it's taking ages... am i doing something wrong?

i unlocked a nexus 5 and got the same problem, formatted data, all seems good now
is there a way to save my data? my phone is oneplusone
if you use twrp to flash xposed, it'll still work. But your data is still encrypted.
Should I do anything else after the Formating data (install TWRP again, root again...)?
I remember that I did format data in my last phone and it completely deleted everything including OS, so now im little afraid.
Currently I can't do nothing in TWRP, not wipe and not backup...

Just format data and you will be able to use twrp.

Thanks, it worked! Too bad that the only way to get this is by loosing all the data .
Hi all,
I followed instruction on installing TWRP and also have root. I also installed the no-verity-opt-encrypt.zip file, but I still can't access internal SD. It says 0mb. Also after installing the zip it similar stated 'unable to mount'.
When I try to format data it can't mount it.
am i missing a step??
ideas?
Thanks in advance...
PS: not sure if this is relevant, but it keep coming up with the same flash screen message: "keep system read only?"
I tick the box says don't display this, and swipe to allow modifications, but get this message every time.

You have to format the data after you installed twrp. And then you can flash supersu and no verity opt thingie.
Thanks for the reply... It wont let me format it. 'says can not mount'
I'm having the same issue here. Although I can root, I cannot wipe data, so no way to install a custom ROM
Guys I am in need of help. I did not fully understand step 10 in TWRP installation guide and just skipped originally. I did notice I could not wipe anything but thought I would be fine so I just dirty flashed custom ROM assuming wipe would work afterwards and I can clean install after.
I am obviously stuck now with 0MB internal storage shown along with no access to phone since it says upon boot that verification has failed and that I need to reset my phone.
Now, I do have important photos/datas which are invaluable and thus do not want to lose... I did hear other guys restored their nandroid backup and were fine.
My question is, is there any way for me to access and back up my internal data somehow? I did hear something like flashing a stock firmware via Odin without the cache inside. Could someone confirm that this would work please? Would really appreciate a response. Thanks guys.
I did try this:
If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer no-verity-opt-encrypt.zip to your device over MTP* and flash it using [Install] in TWRP.
But TWRP would not allow me to flash because it said it could not mount storage. I presume this is because I exited TWRP...
Please, any guidance would be much appreciated.
Do a wipe, system, data/ dalvic , and cache . Do NOT check internal storage and SD card...reflash your rom

Thanks for the reply but I cannot do that since the phone does not let me wipe from TWRP due to the encryption issues I believe.

Thanks man. I am aware of this but have not done so which is my problem haha. Does anyone know of this set PIN before flashing stock rom on ODIN please? I obviously cannot since I cannot boot to system but I do not want to make assumptions like before, go ahead and cause myself more stress...
Hold up, have you flashed SuperSU? That should be the only thing stopping you from being able to boot up. After flashing TWRP and a custom rom you need to install SuperSU to be able to boot.
Either try to flash SuperSU using TWRP built in ADB or buy an external sd card and flash from there. You don't need to disable encryption and in fact, that zip you tried to use actually wipes your internal storage anyway so don't try it again.
Had this fixed on my first one . Had to return it and I cant find how i fixed it. Rooted. TWRP gives error message cant mount data. I cant backup or restore. Can someone point me to the fix, please?
Please note any instructions contained within this post are to be followed AT YOUR OWN RISK. I am not responsible for data loss, device failure, or any other form of damages resultant from the below post.
Final Edit: Method below tested and working on my SM-T580. Please read entire post before making any device modifications.
The reason you cannot mount /data is because TWRP does not support Samsung encryption, and your /data partition is encrypted by default. To fix this, you must disable encryption and FORMAT (not just wipe) your /data partition. You will lose all data on your device by doing this.
To disable encryption you must flash this ZIP file by ashyx via TWRP. I will update this post momentarily with the link.
Edit: Procedure that worked for me is as follows: [YOU MUST HAVE A ROM FILE TO REINSTALL]
-oem unlock and flash twrp
-format data
-wipe cache, dalvik, system, and data
-back out to main menu and reboot recovery
-flash your rom of choice back onto the device, I personally am using Fenix v2 found on XDA
-flash ashyx zip *not sure if this is actually necessary but it couldnt hurt, I flashed this file at this time
-reboot system
-then reboot to recovery to flash xposed, sd patch, etc
-you will see that twrp successfully mounts /data
Good luck!

What? Not sure what you meant but it seems there is more to it than this. For some reason my device is forcing encryption across all sorts of wipes and such so I am currently trying to figure this out as well, will update if/when I figure it out
Edit: got it, updating post and sending you a PM
So I just bought this Tablet and I wanted to Root it, but I immediately noticed that in trying to flash anything, this verification thing gotme stuck in a bootloop. I looked further into it, and I need to patch dm-verity out, however, the latest .zip I tried is for Android 6 it seems, as when I tried to flash it and then let TWRP make modifications, it still got stuck in the Verification Error bootloop.
Now I flashed the original system to it again through Download Mode, and that fixed the bootloop. However, I then went into Odin, flashed TWRP, went into TWRP, tried to do as it said in the guide where it says I need to "Wipe Data", but when I try to do that it says "Failed to mount '/data' (Invalid Argument)". So what now? And does anyone here have a dm-verity patch for this tablet that supports Android 7? Thanks

Bit of an eye attack, but it seems you didn't follow the instructions at 5e.
It specify states NOT to wipe the data partition, but to FORMAT.

These instructions are a tad simpler.
To disable forced encryption, disable dmverity and mount internal storage:
(Note this MUST be flashed after SuperSU if you intend to root)
1. Boot to Twrp
2. Format Data partition using the FORMAT DATA button under Wipe options.
(Note: This will wipe the internal storage)
3. Check DATA is mountable.
4. Install SuperSU (if root is required)
5. Install boot image patch below.
6. Reboot
Boot image patch

Hmm alright, I actually tried that before but it worked this time after I reinstalled the Stock Firmware multiple times and did multiple resets as well, thanks
So do you have a no-dm-verity.zip for Android 7 for me? Or does the one from the thread work?
Oh and, I want to flash Magisk, so shall I flash Magisk first and then no-dm-verity? I am pretty sure that is correct assumed of me.
EDIT: Thanks for the no-dm-verity zip, will try it and I will also try Magisk Thanks for all the help, has been a while with Samseong devices for me :/
EDIT 2: As far as I remember, doesn't Magisk disable dm-verity to begin with when it flashes itself?

Will work on Android 7 too.
If you flash Magisk you shouldn't need the patch.
I tried creating a system backup through TWRP just now for the first time ever. Throughout the process, it gave me multiple messages saying "unable to mount data" and the same for some other folders, and when the backup supposedly finished, it just said failed.
Is there anything I can try without actually wiping either of the partitions? This obviously because I'm trying to create a backup so I can wipe afterwards.

In twrp main menu screen select ' Mount ' menu and make sure mount data is ticked then go back and try backing up again.

That's the TWRP version that I've got installed.
I just reinstalled both stock firmware and reflashed TWRP but the exact same issue persists. At first I was able to mount data though, I could flash zips such as Magisk etc. But after having set everything up again on my phone, I couldn't mount data anymore.

Maybe I wasn't very clear.
I flash the stock firmware, set that up to enable OEM unlock. Then flash TWRP, wipe /data, flash magisk and other required zips (at this point, data is mounted). I then set that all up however I want, install apps etc.
If I want to create a backup after all that, it doesn't work cause of the unable to mount /data and /storage.

Sounds like your device is still encrypted
Did you flash the no Verity encrypt zip file
Also I said to format data not wipe.
In the mount menu these are the options I have enabled.

You're right, I formatted data, not wipe.
I did flash the no verity zip, does the order in which I flash Magisk, no-verity and RMM state unlock matter?

The instructions I followed to install twrp
Flash twrp (which you have done)
Format data
When finished reboot back into twrp(use twrp reboot menu option)
Flash no-verity zip via twrp ( have to make sure you have it on internal storage or SD card)
Then flash everything else
Not sure if you need RMM state unlock if your bootloader(OEM) is already unlocked in developer options though.

Just as matter of curiosity I use FX file explorer (root) in the menu filesystem it should tell you what format your data partition is mine or ext4. I have read that some people through twrp have changed it to something like ext3 and then back to ext4

I think that second thread you linked may have done the trick.
At first it didn't seem to help, but when I tried it again after reflashing everything, I am now able to mount /data.
I'm still in the dark as to why this happened and hasn't happened to anyone else other than the person who created that file, but either way, thank you very much for your help.
