[SOLVED] Cannot mount /sdcard or flash in recovery following phone encryption

Hey guys,
I recently encrypted my phone for my work e-mails (the Exchange server required it). I made a complete Nandroid backup and also entire Titanium backup before encrypting, just in case something went wrong. But the encryption went beautifully.
However, I've noticed that I cannot mount /sdcard or flash anything from recovery. I can't update my Franco kernel or CM nightlies... It's a bit annoying because I want to keep flashing! lol.
My phone asks for my password everytime I reboot (in order to decrypt sdmount and mount the ROM), so I'm assuming this is the reason I can't mount it in CWM recovery.
Anyone know of a bypass or fix for this?
I don't really feel like restoring nandroid backup or doing a factory reset everytime I want to flash a new nightly, it just doesn't make any sense (besides I haven't even tried to see if I can restore from nandroid or factory resetting, they might not even work because it can't mount /sdcard?...)
I've searched around the forums for some complex solutions such as using ADB or Odin but I'm not interested in that.
Thank you!
UPDATED:
Ok guys so basically restoring from nandroid did not work because of the sdcard mount error.
I did a factory reset, erased all data and format system. But I couldn't format sdcard or even user data as it didn't have access... Basically the phone got bricked from then on and I had to completely restore back to stock bootloader/recovery/stock rom with adb/fastboot. Instructions are found here:
http://forums.androidcentral.com/nex...e-restore.html
Hopefully this will come to use to someone else. I've heard that TWRP does not have this sdcard mount problem with encryption as does CWM, so that's what I installed this second time around.

Why don't you just transfer the files regularly without entering recovery mode?
The recovery doesn't allow mounting to the PC. It just doesn't work.

I've never mounted to PC in recovery. My files are backed up on my computer and nandroid as well.
My issue here is that I can't regularly flash new nightlies (and thus mount internal /sdcard to do so) following the phone encryption.
Since my internal /sdcard path is encrypted with a password, CWM recovery can't bypass this and it gives me the error "cannot mount /sdcard".

bump?
Any help would be highly appreciated!
Is this a lacking feature in CWM Recovery? Have the developers looked in it? Or is there already a fix for this without doing an entire factory reset?

Daily bump.
Anyone there? (echo...)

If you want to recover the data from SD card, you do not use the SD card.
You can try to recover the data from the card with some specific software.
I will try to fin one I used before.
It will take few minutes... do not use the card.

Many thanks, this link helped me restoring my Nexus 4. I enabled "encrypted storage" and wanted to root the phone and almost bricked it.

It's also possible to flash the stock recovery with odin, then do a real factory data reset and be able to install a custom rom, after (or before) which you can reinstall a custom recovery.

You need to wipe the data partition in TWRP in order to decrypt it.
wipe/format data/type YES
TWRP doesn't yet support samsungs encryption.
wiping data will obviously remove everything, so backup first.
immediately after wiping data, flash an updated supersu, or dm-verity disable
Flashing a rom over an encrypted data partition will do nothing to solve it unfortunately.

S8 TWRP Error

Hi all,
Yesterday I managed to root my phone all fine with TWRP and SuperSU. Then after incorrectly uninstalling the security log agent and getting a million errors I foolishly deleted the stock OS.
I have download the correct version for my phone and location but now TWRP fails to launch.
I get the follows errors when booting to the recovery.
Failed to mount /data (invalid argument)
Unable to recreate /data/media folder
Unable to mount storage
Unable to mount /data/media/TWRP/.twrps
I have googled a millions things and am still stuck.
Interestingly tho, If i install the Indian version of the OS, it loads and roots no problems (I'm from New Zealand).
Any help greatly appreciated.

Hi
Your internal memory now corrupt you have to format it.
Use twrp wipe option select internal memory then format to fat32 after that again do same thing. This time choose its original format type.

Hi, thanks for the fast reply.
Iv'e tried this option, I installed the Indian OS which works with TWRP, formatted the Data drive to FAT (Fat32 isn't an option) and then back to EXT4. I then used Odin to Install the carrier firmware I want to run and the same errors occurred. Could it be a problem with the actual OS?
Edit** When I install the Carrier firmware I can't get TWRP to open, these errors occur as soon as it opens, and then it crashes and reboots

Hi hi, tried that several times. Would still like to find out what is causing the issue but have now installed Nemisis and all is working perfrctly which makes me think it's the OS as opposed to my file system, considering I have installed multiple other versions and ran TWRP no problems.

Got same problem here. Installed TWRP to flash a custom rom, TWRP can't mount /data.
Google doesn't give me any solutions
This fixed it for me:
- download stock firmware from sammobile & flash with Odin
- go into stock recovery
- wipe data and cache partitions
- flash twrp using odin
After that, TWRP was able to mount /data and function normally again

Backup S8 - G950F with TWRP

Hello guys,
i've just received the Android 8.0.0 and as soon as i got it, i root-ed it. Now everything is fine but the only problem i have is that i cannot backup the whole system as it is right now with TWRP.
When i open TWRP in boot and i go to backup all files it gives me the following error : "unable to mount //data". How can i solve this problem without formatting it again ?
Thank you.
P.S : i added a photo as an attachment with the error.

Format both to fat and back to ext4. I would like to know if there is another way. You can backup needed apps with titanium and restore later.

When you say both, you mean "data" and what else ?
LE: I did it for "data" and now it seems to work but will try when i have the whole rom ready.
Thanks.

Update : for that time being, it seemed to work. After that i installed all the apps and did all the settings and now when i go to backup it gives me the same error. This is a part of the recovery.log after the failed backup. By the way, it failed at almoast 95% .

Can anybody help me ?

Did you first format data to fat and back to ext4 and it got fixed?; was it showing free space in /data/media, not like on screenshot where is 0mb and it's broken? after you tried to backup it broke in the process? Try to wipe, install custom rom and back up it. Try external sd

After the first format it got fixed, yes. And i did make a back-up.
After that, i booted, i installed apps and so on and when i came back to twrp the error reappeared and /data got corrupted again.

I never got blocked out for 7 days even though i installed at least 20 times different roms in the past days.
When i rooted i installed the RMM .zip . Are you sure it's from there ?

Yes, I had the same problem. I am back on Android 7 until there is a good discribtion in the right order to get it right. No one can tell me the right solution. They are all diferent. So I wait for now.

I've tried using a twrp for oneplus 5 because they seem to have had the same problem. The good news is that is seemed to work as the /data remained ok. The bad news is that the phone would enter a loop.

I found the fix !!
dr.ketan helped me make the right files to flash. Now i have made the first FULL backup and i am amazed it works. In recovery /data appears mounted. I went there 3 times to make sure :fingers-crossed:
If you want to I will ask dr. ketan if i can upload the files.
Thanks for the help and have an easy day!

OKé, is he on the forum, dr ketan? Perhaps you can tell us now because you have the solution.

if you follow the video you have the "/data" problem and after that you solve it with the solution from dr. Ketan.
I don't know if you can flash directly the zip from dr. ketan, haven't tried it. In theory it should work but i can only confirm what worked for me.
Keep me updated on what you did.

Best step if one is on oreo stock and just want twrp +root
1.flash twrp with format data (will wipe Int storage)
2.flash magisk (from ext SD)
3.flash data mount fix(from ext SD)
All three to be flashed without reboot in between
Then must have to reboot to system
Now next time when reboot to recovery, data will available in twrp
Who already have oreo rom +twrp then simply flash data mount
Who are on nougat custom and want oreo custom rom
1.factory reset (no need to format data)
2.flash oreo custom rom
3.flash magisk if rom doesn't included
4.flash data mount fix
Reboot to system once
Done

Phone not accessable after trying to install Custom Rom

Hi,
so i've tried to root my phone and then to install a custom rom. the root went without any problem. After the root, i tried to install lineage OS 16.0 and followed this guide:
https://forum.xda-developers.com/redmi-note-7/development/rom-lineageos-16-0-t3923203
i downloaded the rom and gapps, put them on my root directory of my phone and then i wiped System,Cache ,Data, Internal Storage and Format Data. After wiping, the roms were gone, so i rebooted and transfered them again into the root directory. Then, i went onto installing (just like i did with magisk) but an error occurred saying:
E: String resource 'zip_compatible_err' not found. Using default value.
Zip Treble compatibility error!
Invalid zip file format!
Error installing zip file '....'
Updating partition details...
...done
Ok. So then, i tried to install another Custom Rom so i went for Oxygen OS, it actually did install but then i couldn't boot into it because it was telling me there was an 'Android System Error'. Ok, back in TWRP, i wiped everything and then i tried to install the Original ROM but i got the same error as above.
For now i tried to download the miFlasher tool but it only wants to download some driver and it literally takes forever.
Hope you can help me...

Those recoveries are old.. Use orange fox recovery 10.0-2 it will work and format data then install rom.

@BlackGarnett
Thanks, that help me on a quick one!
@loseyourself
Also thank you for this advice, i'm new to rooting smartphones and install cfw since i was using iPhone for the past few years.
But now i got another new question: if i use orange fox recovery and i run a backup with it (i think there will be an option to do a backup), then i format all data and internal storage, can i still recover from the backup or will it be deleted?
thanks again!
