Can't mount system as writable in TWRP (device or resource busy) - LG G6 Questions and Answers

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

Bootloop and stuck on LG logo

I was on 10T official. I decided to unlock bootloader, I followed the guide, I my storage was unencrypted...
I have unlocked bootloader and then installed TWRP 3.1.1.
After a boot, I have installed a Stock modified ROM (Fulmics ROM 2.0).
After reboot, the phone is stuck on LG logo, and after minutes it reboots and stucks on LG logo and the reboot...... etc etc
Entering TWRP again, it says my Data is encrypted and asks me for the password.
I have formatted Data, and reinstalled Fulmics ROM, but, same problem. Stuck on LG logo. Now entering TWRP there is no partition encrypted... but...
What should I do now?
Reinstall stock using LGUP

Restore the official firmware with LGup, install again the TWRP, make a format data (format, not wipe), install whatever you want to get twrp stuck (SuperSU, magisk ECC...), Reboot system, then reboot in twrp, manually or by a rebooter app, wipe system, data, cache and dalvik, install fulmics with your favourite aroma settings, after that reboot recovery, flash the 2.1 ota, and reboot system.
Now wait some minutes, it'll reboot again once, it's normal, when happens just wait again for some minutes, and it should boot normally.
I've installed this rom a bunch of times (for a bunch of reasons) and never had Bootloop problems doing this.
Good luck:good:
Thanks, stock firmware like this one? https://forum.xda-developers.com/lg-g6/development/rom-h870-10f-rom-imgs-kdz-t3615183
And in LGUP should I do anything particular? Or just reinstall kdz?
Then, should I format only Data partition or also system or others?
You can decrypt data through fastboot

Here it is the kdz: https://lg-firmwares.com/download-file/?fileId=10110
Just reinstall the kdz with upgrade option.
You have only to format data (not wipe, remember).
Thanks, worked!
Mmm... No, I was able to reinstall stock rom, but then, when I try to format Data I get error like "Failed to unmount /system (Device or resource busy)" and then "Failed to mount /data", "Unable to recreate /data/media folder...
And also when I install Magisk I have those errors... (Failed to mount system and data).
Booting up, stock rom is ok, and also Magisk, so phone is rooted.
But when I reboot to recovery and I install fulmics rom, it seems to install correctly, it shows a final error of mount system and when I boot I still have stock rom, without Magisk or fulmics settings... so It is not installed fulmics rom! Tomorrow I will try another time. By now I keep stock rom rooted. Anyway I'm happy to see how easy is to reinstall stock rom.

In my case the official twrp from twrp.me had the problem of unable to mount system. I read all the twrp Guide from LG G6 in rom, recovery root section and I read that had some problems and they posted an usefull twrp. Try downloading twrp from these post.
I've installed experimental TWRP over official TWRP posted here https://forum.xda-developers.com/showpost.php?p=73071238&postcount=228 and works, no more mount error.
Now I have installed Fulmics rom. I'm happy!
Thanks to all

HELP .
Tnx in advance ,

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:

Can't create a backup through TWRP.

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.

Thanks for your reply, it doesn't actually let me tick that box. Nothing happens when I tick it. It also says that the data partition is 0mb. Any idea what that might mean?

Which version of twrp are you using
Latest is 3.2.3.0 which should fix the data issue ( it"s a known issue).

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.

Can't accsess /data in TWRP and Have no root

Something recently broke Twrp so now I cant touch my /data partition, ive read that I need to format my phone to fix this issue, the problem is that a recent update from Lineage OS is what broke it I believe, and I updated from within LOS (check for new updates download and install) which auto restarted, so when I went to go back into TWRP to reflash Magisk I started getting the issue
So now I have no root, and no twrp abilities that I know off, which means I cant use a decent backup program
can anyone help?
EDIT: I don't know if they has any relevance but ADB does have root permissions,
EDIT 2: I found out that I can reinstall magisk VIA ADB Sideload from within TWRP, as such I now have root again
@foxtrotdragon: If you can get into TWRP then reflashing Magisk shouldn't be a problem. However, if /data is encrypted then Magisk may not flash, it needs to be able to place some files there. You'll lose everything on internal storage, but formatting /data is the only way forward.
If you can't boot into TWRP then the obvious solution is to reflash recovery from a PC.

Getting into twrp is no issue, the issue is that TWRP cannot read the internal storage, it can read external fine, but fails to read internal storage, which means i cant flash anything, an reflashing twrp does nothing
im fine with reformatting the phone, but i need to backup my stuff first, which i can not do since no root
@foxtrotdragon: Unfortunately for you, backing up the contents of your internal storage is no longer possible, unless you can think of some ingenius method to decrypt without formatting. Formatting /data is your only option. In the future, you should make backups *BEFORE* disaster strikes.

help about /vendor

im having big problems about vendor. for start im giving some info:
device: mi a1 (tissot)
current os: lineage OS 17.1
root: yes
twrp: can install or use just booting .img
i unlocked my device and installed twrp. there is no problem.
i wanted flash lineage OS and i wiped my device. gives error about cannot mount /vendor
i installed treble supported twrp and installed lineage OS. flashed magisk. installed microg...
then i tried flash mapsv1.zip which is recommended for microg. then booom. another /vendor error.
now i can boot device. i can use everything except gps. google maps app cannot found location. yandex maps can found and i can use it until lock screen or going main screen (or another app). then it starts stopping everytime until i clen its data and cache. then again... in chrome when i open google maps and try found my location chrome stops.
i tried to change /vendor/etc/gps.conf. its still same.
what to do now guys? im worrying about if i try re-flash rom it doesnt flash and device bricked. any solution without re-flash rom? what causes to cannot mount /vendor after solved it?
What exactly did you wipe? I think you wiped vendor, or bumped your O.S. from an old firmware. However, wiping system, data and Dalvik was more than enough.
To solve this, the worst thing to do is trying to hook around. Just reflash the latest original firmware and start again.
Keep in mind that you might need to backup your stuff first.
Use adb pull and push commands in case your device is rebooting too much. Check if device works well this time.
Next, open adb access from device and reboot fastboot to reflash your custom recovery, then reboot recovery and wipe just these items. Finally, complete Rom flashing procedure, depending of your needs.

Dalvik cache , system, data, and cache. My device is not rebooting too much. Sory if i couldn't explain. Everything working fine except when an app tries use my location, app stops running, i cant flash anything right now.
İ thought anyone knows mapsv1.zip file(microg.org) and which files are replaced or added by this file when flash it. And can i do it manually? Btw i can read and write /vendor file with solid explorer
İf needed to re-flash rom thats ok but i think lineage OS was perfect for me until this error. And a last thing: can i backup my settings. (İ already took backup of everything in stock when unlocked bl)
Thank you for help
Edit: gps problems started when i tried flash mapsv1
ROM could be perfect, but what I doubt is how perfectly you followed the procedure. Again, better start from zero, being sure you have all the prerequisites (latest firmware included). My humble opinion.

Okey ilk try it and share the result night. But is it possible to backup settings of phone?
Well, that's why in step 0 is always recommended to backup you phone. At this level you should have nothing in settings, since you wipe it all... However, that's better, that's the goal of a Clean Install after all. Each ROM has its own flavour and is not recomendable to overwrite these values from a backup, if you're changing ROMs. What you could do, was to backup your apps and some settings with a third app like Swift Backup, or older Titanium Backup, before starting it all, or else, making a complete backup from recovery, in case you end with a problem with newly installed ROM (recommendation here is disable any screen security lock before doing Backups).

İ did it all. Step by step. But i realized something. That errors doesnt matter on my device. Bcs when i flashing stock mi flash tool said failed but i booted system and everything working fine. İ installed persistent twrp. Same error. Then wiped. Same error but wipe completed. Than i flashed this zips single and booted everytime: lineage os, magisk, backup of migrate. Everytime it said cannot mount vendor but all of this apps and os and recovery working fine

İ am using treble support twrp, flashed stock rom via mi flash(said error but worked fine) then how to treblize a device? And is this required for anything(like a rom, an app)?
