Hi Guys
Im having trouble flashing new Roms to my S7. When I enter TWRP recovery, it shows my device as 0MB and it doesnt picK up any files. I looked into this and read that Encryption should be disabled on the handset. I followed instructions to do this and noticed that there is no option for Encryption Protection. Its not there!
I disabled any passwords and Pin numbers to erase decryption and it still didnt work!
last resort was to try a factory reset and the device restarted to recovery and failed as TWRP recovery cant find any mounted devices due to the encryption crap.
Any help appreciated.

Hi mate
Seems like you did not format your data partition during TWRP installation.........
Try flashing your custom rom from the External SD card......your data partition has all your app , files , passwords, photos...there is still a chance that there it may be a incompatibility issue between your apps and the new rom....that is why they recommend a factory reset when flashing a new custom rom

hi mate
thanks for your reply. I dont have an external SD card
Is there any other way of sorting this? I am downloading a stock rom as we speak.

Hi
TWRP can not handle Samsung encryption . if you wish to use TWRP and have access to the Data partition ( internal SD card) you need to format it so the encryption is disabled ( you lose all your apps , data and user configuration AKA factory reset) , you can have TWRP and data encryption but mods and roms have to be flashed from external memories also you will not have available MTP in recovery or factory reset from it.
There is no way to disable data encryption without format data.....
Ok, I got a friends SD card and placed the Rom on there. I can now see the Rom but the trouble is, TWRP wont let me wipe Dalvik / data / system / cache as it wont mount the storage....
can I still apply the ROM?
Unable to restart your device. The integrity verification has failed. You need to reset your device to factory default settings. This will erase all of your data.

That is why I point it out " factory reset is recommended when flashing custom rom" if you wish to flash a custom rom you will have to format your data partition and flash the data verify file........

I have tried to format/wipe data. TWRP keeps saying it failed as it cant mount the storage.
I tried flashing the stock rom via odin and it also failed as it goes to recovery to wipe data and it fails again as it cant mount storage.

How did you flash the stock rom...which files did you use?
Wipe data is not enough you have to Wipe / FORMAT DATA and type yes....
1 To get rid of encryption, go to "wipe", format data (TWRP) (keyboard will pop up) then type "yes" and format it, then reboot to recovery
2. After flashing this, hit wipe, full wipe (this will clean all internal memory and your data will be lost
3 you can test if encryption is still enabled, if TWRP shows error about not mounting data your phone is still encrypted

What version of TWRP are you guys using and what version Super SU?

Can't flash anything through recovery. (failed to mount "/cpefs" (Invalid Response)
I recently got this phone and I've been trying to install a custom rom, however, I can't seem to do anything while using TWRP. For some reason the file explorer shows no files and no /storage folder. It also says that the /system partition weights 0MB. I've already tried formatting the /data partition from EXT4 to extFAT, but it won't let me because it cannot mount the "/cpefs" partition, which I've been unable to find any information about.
I can flash the stock firmware trough ODIN, and I can flash the recovery. The internal storage works fine, but nothing shows up when I open TWRP.
I've tried formatting the data partition, repairing it, changing the partition format, wiping, installing a custom rom, installing superSU. But it won't allow me to do any of those things. Either "/data" can't be mounted, or "/cpefs" can't be mounted while formatting /data.

Which phone you're using?
J7 Pro?
Secondly make sure to enable OEM unlock options from the stock ROM's Developer option!
Thirdly check the recovery patches etc of the desired recovery's webiste (you're using) and flash it through the recovery if you're facing the problem!
It'll work, mostly some users said they fixed this by the above mentioned step!
If no luck, maybe someone will sort it out for ya, soon! :laugh:
Good Luck! :good:

Thanks for your reply. The model of the phone is SM-J710MN. The OEM unlock option is enabled, otherwise I wouldn't be able to flash the recovery. I am trying to use TWRP. Where would I find a recovery patch for this model?. Everything works fine in the recovery, but it won't let me wipe/format/repair or change ANY partition. It can't mount anything, and the error that I see the most often is that it cannot mount the /cpefs partition.

try flashing a lower version of the same frimware you've already installed e.g if the latest is nougat 7.1.1 with the recent security update, try flashing with another nougat version that is lower to the recent one's security patch #
I searched for an answer and noticed it's a common issue. I am trying to flash a kernel on to my already flashed rom. I was wondering if there is a more current fix. More importantly, how can this be avoided in the future. Thank you guys!
Its caused by a bug/error with either the filesystem or encryption.
Did you wipe data after flashing the new ROM? Data from stock usually doesn't work with custom ROMs.
Do you have a PIN/password on Android?
Are you using the latest build of TWRP?
Press the menu button at the bottom of the screen in TWRP and post what the error message is in the red text.
It's caused by no root access

Something is probably wrong with the data partition. TWRP should always have root access.
Try in TWRP:
Wipe > Format Data > Slide to format
This will erase the data partition, so backup everything to a PC in Android first if needed. It should allow TWRP to mount /data again.

I've debated on doing this. I'm not worried about losing pictures texts etc as they're backed up.
I read that it essentially leaves the device with no OS. If that's wrong please let me know!
I have found that if I choose Slot A and reboot system it reboots me in to TWRP. If I choose Slot B it runs the OS like normal (except I still have issues using Facebook and it's services).
The ROM works and I can perform all the custom mods on it. I just want to flash a kernel and the problem persists. 0 mb in storage.
It's trial and error at this point. Fail fast fail forward. I have another phone I can use but I love the OnePlus. Any help will be appreciated!

I'm not willing to risk it until I know how to get the custom ROM on to the storage to flash it.
Yes formating by typing in yes will wipe it all,everything including pictures, with no rom on it at all. If u choose to do that, don't close twrp. Instead you should be able mount after wards, once mounted transfer the magisk zip, twrp, and your custom rom(has to be 1.5gb not 200mb through magisk). Flash magesik, install ram disk twrp, install rom. That was a method I've done before but if u want to keep everything there is other way
fastboot boot twrp.img, that command boots twrp if u have it or don't, installing to ram disk makes it permant...this boot command is just a one time thing each time. It's what I do when new firmware update, I loose root but I regain it each time
Never heard of formating data removing the OS, that would be if you wipe the system and normal wipe is like a factory data reset and therefore will not wipe your phone of the OS

I attempted to format. It said
"failed to mount /data (device or resource busy)
"unable to mount storage"
Try this in recovery, sometimes its known to work.
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to EXT2.
Repeat the same process selecting Ext4
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to back to EXT4.
Try formatting data after this.

Since you dont care about the data on the phone I would just do 1 of 2 things. 1st I would reflash twrp on to you phone if that doesn't work then I would just grab the fastboot ROM and just flash your phone back to full stock reroot and install twrp from scratch. I would not try to start repairing partitions. I wouldn't want to worry about screwing up the EFS partition
Well in an update, I formatted the
Storage and now I'm stuck in bootloader screen. It's unlocked but I'm having a hard time flashing a ROM through adb.
I use the twrp version 3.3.1-2
Best would be to just use fast command to boot it
But it should be under wipe/format data/then type in yes
That was what I was trying to have you avoid. If your can boot to fastboot download the fastboot ROM I told you to and run the flash-all.bat file. If your on 9.5.8 make sure you use the fastboot ROM of the same version. Do not flash azip of a different version firmware like 9.5.7.
It happens to me any time I'm in twrp and flash a rom then reflash twrp. It doesn't matter if I flash Magisk or not the issue always happens. What I do is use a USB C flash drive and plug it in when I want to flash/backup a rom. This way I can always access it. After flashing any rom then booting I'm always able to access my internal storage again. It seems like a bug in twrp.
The strange part is when this bug happens your files are encrypted in a 0 folder but you can still copy from your PC to your internal storage while in twrp.
I essentially soft bricked my device. Called OnePlus and they got me up and running. That's awesome that they have that service!
Are you removing all security? Pattern, pin and fingerprints? Are you decrypted? Never had an issue with flashing a ROM causing these issues which is why I'm asking. Something you've done at some point is causing this
I'm not sure what that was. Ironically enough I am now stuck in TWRP boot loop. Hopefully I can figure this out otherwise I have to call oneplus again.
I will admit I may not know everything but it's trial and error. I don't have anyone to really teach me this so I try to read the forums and learn. You guys have been great!

Please post how you fixed as it may help someone in the future. Thanks
Was installing the wrong version of TWRP so flashed again via adb and is working. The zip file was for the 5g model I think but I've got the non 5g but works ok
Today I unlocked my bootloader and installed orange fox recovery, I tried to install TWRP but it wasn't being permanent, it was just disappearing after once I boot the device to system. Whatever, after I installed Orange Fox, it was permanent but I faced another problem, I couldn't mount my data, my internal storage couldn't be selected so I wasn't able to flash anything, usb otg option was also showing nothing but the device was connected to a PC and my data was encrypted which requires a password or pin to decrypt. Though I didn't have any screen lock, but I tried out many pins and passwords to decrypt, but it all went in vein. I tried formatting data and enabling a screen lock and tried that screen lock too but it didn't work out.
Now what can I do to Decrypt and mount my data so that my internal storage shows up with the data I have?
NB: My battery backup also dropped hugely for some unknown reasons, how do I fix that too?

Custom recoveries like TWRP and OrangeFox cannot decrypt Android 12 ROMs, which means if you are on MIUI 13 you have Android 12, you cannot decrypt internal storage yet.
USB OTG means to connect to an external hard drive or flash drive, not connect to PC.
2 ways to deal with: 1) put ROM in microSD card and put the microSD card into the phone, TWRP and OrangeFox should be able to read microSD cards. 2) use ADB sideload in TWRP/OrangeFox to flash ROMs/Zips files. You need PC to do this. Look up on Google how to flash with ADB sideload.
Hi Guys! I Found a new Method how to Decrypt the Storage.
1. Go to Wipe and wipe the Internal Storage (First make a Backup to Your PC)
2. Go to Backup and Backup Something, like Cache
3. Go to Menu>Mount, uncheck the Data and Check it.
4. Format the Data with Typing yes and Reboot
4. You're done and Enjoy!
TRWP beta can decrypt internal storage of A12.1, I am using it and it works fine.
OrangeFox beta builds are able to decrypt a12 data no probs. Even unoffical twrp beta can.
