I just installed twrp on my device and tried installing magisk but it just keeps failing to mount /data
So I reformated /data to ext3 and it kinda worked fine, I got Magisk installed and got the device running normal but the play store wasn't able to install anything anymore.
So does anyone have any clue what I could be doing wrong?
TWRP: twrp-3.2.1-0-cheeseburger
Magisk: Magisk-v15.3
EDIT: Tried again with twrp-3.2.1-0-universal-codeworkx-cheeseburger and it seems to work fine now.

So guys, I downloaded the latest CM nightly through the CMupdater app, I rebooted into recovery TWRP 2.6.3.0 at that moment I think, when I tried to flash my update it said "Unable to mount /system" and just stood there, I rebooted into recovery again and tried to mount it from the mounts menu without result.
Next I updated to the latest TWRP but the problem persisted, changed to the latest CWM and that too, is unable to mount /system displaying the message "Error mounting /system!"
I seriously don't want to lose my data as this was a simple update so I didn't make a backup but I don't know what the hell else I'm supposed to do.
Oh and BTW, trying to boot to system leaves me at the Google screen for an indefinite amount of time.
Thanks in advance
Edit:Turns out formatting system doesn't delete my data, I got impatient and did that, problem solved.

Thx Josh
So, i just started getting this same error after updating to TWRP 2.8.2.0, I tried wiping the system and still got the error? I downgraded to TWRP 2.8.1.0 and wiped system again, and that seemed to fix the issue. Not sure if it was my own bug or 2.8.2.0 but just wanted to leave feedback for the next person who may be searching for help.
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
Hi everyone,
Just got my new G6, after much pain I managed to unlock the bootloader, install TWRP (v3.2.1.0) and to root it with SuperSU (stable release 2.82).
For now I'll keep the stock rom but I wanted to make a backup in case something went wrong with other tweaking I might do and I couldn't because TWRP couldn't "mount /system (device or resource busy)".
So I went into the mount menu and tried checking system but it just won't. I can mount it as read only but I can't mount it as writable.
If it's of any importance, I couldn't get magisk to install to root the phone and had to use SuperSU instead.
I could do the backup while mounting system as read only but I feel like it might be an issue in the future (for custom roms or even restoring the backup maybe ?) if I can't fix this issue.
So does anyone how to get TWRP to mount system as writable ? Thank you

Have you formatted data trough the dedicated option in TWRP? Format, not wipe, where you have to put "yes".
Anyway you can try with Melina's TWRP which solves many problems of the official one: https://forum.xda-developers.com/lg-g6/development/recovery-twrp-3-2-1-unofficial-fixes-t3722199

I did try it once after the magisk install failed and I assumed it was because of that issue but I haven't tried yet with superSU correctly installed. Should I immediately try the backup after formatting or boot the phone once before ?
The issue I have with Melina's TWRP is that it's not compatible with fulmics and if I were to install any custom rom I think it would be that one (to keep stock camera mostly)

Format data, reboot recovery, and try to install magisk or mount system.
For Melina's TWRP it has NO problems with Fulmics, Zefie said that "officially" is not compatible because two users said that they have problems with that TWRP only with fulmics, i can assure you that with last version of both Melina's TWRP and Fulmics i never had problems like those two users, anyway you can try to use Melina's TWRP and if you have any problems just flash back the official twrp.

Alright so it's been a rough ride.
I formatted data, reboot TWRP and then indeed I was able to mount system as writable.
I then did my backup, which said it was successful and the only error it showed then was "unable to unmount /system"
I flashed magisk and rebooted into the normal system and the phone of course was back to factory settings and asked me my google account. Except that when I tried logging in it always showed me an error along the lines of "google play services keeps crashing". (making it impossible to get through the installation part of the system)
I'm not sure why that happened. I had frozen some apps but that shouldn't have been saved since I formatted data right ? and the phone was working perfectly fine before that.
But anyway I didn't really know what to do at that point so I just jumped the gun and downloaded and flashed fulmics.
It worked fine but only with supersu. For some reason magisk just doesn't want to get installed at all.
The rom itself worked fine but I had no root access by choosing magisk in the aroma installer so I wiped again and installed it again with supersu which works.
I also flashed xposed which is also working as intended.
So I'm all set for now I think.
Maybe when I need to wipe again I'll figure out why magisk doesn't work but for now I'm satisfied.
In any case, thank you for your help
TWRP on S8+ Oreo Exp9. Failed to mount '/data' (No such process)
Never have had this problem on TWRP before. Neither on my S6E, S7E and S8+ , always updated on latest firmware, rooted and with perfect TWRP.
Until now ..... with latest OREO/exp 9 update .... . Cant make any backup / restore for _ Failed to mount '/data' (No such process)_
How I did try it (for almost two days):
1:Flash G955FXXU1CRB7/ G950FXXU1CRAP (samfirm and WRoid) with odin 3.13.1 / 3.12.3 and Prince
2:Flash TWRP 3.2.1-0 latest
3:Format Data ( yes) + also tried Wipe Data, and Internal Data, Dalvik & Cache
4: Reboot recovery and Flash no-verity-opt-encrypt-6.0
5:Flash Magisk 16 , later on also tried 15.3
6:Reboot
7. Setup and phone works fine
but when booting into Twrp afterwards and try to make f.e. a backup get a "Failed to mount '/data' (No such process)" notice .
Already Tried:
differet odins, firmwares , magisks , partitioning SD, re-formating micro SD ext 3 / ext 4
always same error message after rebooring and never can "mount data" afterwards .
HELP .
Tnx in advance ,
El
here is a person who said that you have to stay 1 week without shutdown phone if y want twrp work with no costumed rom but y can use costumed rom no wipe needed
It's a problem with Magisk. You need to flash a custom kernel or use SuperSU instead of Magisk.
I'm having same issue have tried all of all of that already also have tried going into advanced wipe changing file system, it bring up the /data and will work to flash files but as soon as you reboot it goes back to failing. I'm getting fed up with restoring my phone and adjusting all my settings and apps everytime
Any help would be much appreciated

How can I install supersu without wiping my data and having to restore again, I tried the magisk uninstaller but TWRP can't read /data. Also I tried to Download notorious kernel but I can't seem to get the link to download
I have the same problem. Formatted data multiple times, always the same problem, as OP described it. Is RMM state really the problem here? Or has anybody tried it with SuperSU instead of Magisk? I'm really tired of setting up my phone all over again...

Just tried it with SuperSU, doesn't work either.
after so many tests I discovered that twrp can read and write data only if you flash last supersu beta, magisk and supersu official both doesn't work:
https://forum.xda-developers.com/app...v2-05-t2868133
I had previously been able to flash roms on my ze520kl, had it rooted with magisk running xenon android 8.1
I had some issues with the phone not taking my pin so I attempted to restore and reflash, but nothing had worked so now I've done a full data wipe and its refusing to take any rom zip files including stock.
I've tried reflashing stock boot.img and recovery.img and going back to twrp and reflashing but I keep getting error:7 and its saying that it can't mount /system and /cache
mount: failed to mount /dev/block/bootdevice/by-name/system at /system: invalid argument
What can I do to fix this? Let me know if you need more info
possibly solved, seems to be flashing from internal storage just fine. I was going from external SD before
