Good excuse me, I would like to see if the mount error could be solved: '/system' not in /proc/mounts which does not allow me to remove system apps from a gsi, and I would also like to convert system apps but it does not let me. Which error appears in linksd

Command 'mount -o remount,rw /system' doesn't work on emui 9.1 using an external terminal (Termux etc.) due to EROFS.
On GSI use terminal in TWRP (root required).
Also you have to install vndklite GSI version, nonvndklite is read-only!

Hi ALF, well actually I was thinking of deleting some apps to replace them as system apps, like the system camera, or the messaging app, I was thinking of doing those exchanges, but if it can't be done, I'll leave it as it is, thanks
I'm on the CAOS version: caos-v300l-210117-arm64-bvZ.img

Hello guys.
Yesterday i installed Chainfire 3D from Android Market and then installed driver. My phone is now not booting, just galaxy s logo. How can i delete this driver and repair my Android? It's located on my memory card.
Re-apply permissions to all files. Mount the ext2 partition read/write on Linux, cd to it, and do "chmod 0777 ./* -v -R" and then "chmod 4755 ./system/xbin -v -R". Flush the cache with "sudo sync" and unmount.
By the way, how did you manage to install Chainfire? It keeps giving me an error when I do, about not being able to mount /system read/write.
Is this commands safe for my data or i will lose it?
How i installed? Just by downloading *.apk file.
Are you sure? Installing the apk only installs a tool which takes you to a menu to install the driver. If you don't click the icon and go through the install process inside the app nothing happens, so CF3D is most likely not the cause of your problem.
The commands I posted should still solve it and they don't destroy any data.

You need a kernel which doesn't mount /system as read-only. If you use the latest release from nbates, then I think your only solution is to remount /system as rw either via adb or from a terminal emulator on the device, then install cf3d

Going to try. If the shell script cannot mount it I doubt a terminal will, but whatever. I'm using the SD version with the audiofix kernel (can't remember date) and the MIUI ROM by the way.

My problem is that I installed that driver (CF3D) from tool. Your commands doesn't help. My android still is not booting.
@edit:
problem solved, i reinstalled system folder
I seem to be having the same exact problem, can someone tell me the adb lines to fix this? not sure how to reinstall the system folder
Hello everyone, I made the root using the "all in one" by condi.
the root is fine except that when I use the 'app' root app delete "to delete the files of sony, tells me that I need root permissions.
the version of Android 4.0.3 is R5A.
can someone help me? thanks
----------EDIT---------
with titanium backup I found out where they are system applications
/ locale / vendor / app. I tried to move "crash bandicoot" in / local / system / app and it says it is a read-only file so I can not uninstall it.

I used adb shell
mount: operation not permitted
Check your tablet screen after entering the su command, there should be a window asking you to grant root access. Give root access and you should be able to continue with the remount command.

Hello. I installed emui 9.1 on my mate20pro with the dload method. I unlocked the bootloader again and rooted the system with patched recovery. The phone is rooted, but the system partition remains in ro. I have tried various apps to mount the system in rw, but without success. I have also tried some commands found on the net both through adb and emulator, but nothing to do. I have also tried using rootexplorer which has been granted root permissions, but fails to modify anything, nor to insert or delete files within the system folders. What can be done?

it's the new filesystem called erofs (Extendable Read-Only File System)
So there's nothing to do?
Sorry OP if this is off topic , but its about magisk and root in 9.1
I have the "system partition remains in ro" issue too , its annoying yes , but I have a bigger problem
When "rooted" , the phone app ( dialer ), and the contacts app both get broken and crash .. So I have to fastbootflash twrp and lose root to make those apps to work normally again
Anyone with the same problem ?
I need root so I can change and use the font ( I like ) with a magisk module

Magisk can already 'replace on the fly' file from /system systemless-y.
It dies already support erofs.
Check Magisk documentations.
There is also a way to mount custom erofs partition....
which is?

Build your own erofs partitions (cf. erofs.mkfs)
Unmount stock ones and mount yours.
I just did some test 48h ago on erofs /cust and it seems to work...
-Mounting other file system type on same folder could even work !

Magisk Doc. :
https://topjohnwu.github.io/Magisk/
So far, out-of-the-box, Magisk is already ready to replace systemless-ly files and paths on /system easily when used with modules.
-Module just need a a small tweak to add Magisk systemless-ly compatibility to other erofs partitions like /cust
Another way would be to bind or mount...

my reply was not for you but for the off topic before my reply: contact, ph app and message force close after root.
as I said, there is already a solution about force close.
Anyway I can only write in /system/etc and some over folders

Hi, I saw that you managed to get a custom erofs partition mounted using magisk. I was wondering if the same could be done for the/product folder because that would allow me to fix the DPI scaling issues found on EMUI 9.0-9.1. Would it be possible to see the code for your magisk module?
Ok, So.
After having a look at what I did with this WorkInProgress...
So far there is 2 main way I thought about and played with:
Method A
A1/
Using the mkfs.erofs tool to make your custom erofs partition and mount it over the original one. (mayne umount it before)
Thanks @ph03n!x for his work on mkfs.erofs.
Thanks @ante0 for his android arm build.
A2/
I did not yet tryed to flash via fastboot or adb these modded erofs images.
Method B
What I'm actually doing is just mounting systemless-y with a magisk module whole folders over erofs one ;
In post-fs-data.sh, I'm doing:
mount -o bind $MODDIR/cust /cust
mount -o bind $MODDIR/version /version
With a ~150MB custom /cust it is working ; It should be tryed/perfected for bigger folders.
Another way, to not replace/spoof the whole folders could be to mount the whole list of custom files at their respective path (-to be tested)
PS: I'm not sure if update-binary module's file should be modded with some:
mount /cust 2>/dev/null
@ line 42

I'm rather new to this trying to do something similar on my EMUI9.1 using Magisk, I'm having a problem that i can replace anything in most other folders without much problem like /etc/ for example, but when i try to substitute /vendor/, whatever i put it the folder does not only fail to get substituted, it even disappears from the $MODDIR/system/vendor folder upon restart!
I.e. let's say I create a new file in $MODDIR/system/etc. Upon restart i'm successfully seeing that same file appear /etc.
However when I create a new file under $MODDIR/system/vendor, Upon restart i'm not seeing that under /vendor. ALSO the file is gone from $MODDIR/system/vendor like it was never there.
Any idea what is happening? I've also tried manually mounting in the post-fs-data.sh, where i put the following:
mount -o bind $MODDIR/system/vendor /vendor
That actually caused my system to freeze on the loading screen. I had to reset magisk to non-modded settings in order to get it to run again.
Any help's appreciated.

Hi I have almost the same issue after updating to EMUI 9.1 the phone hardbricked. It only shows as fastboot on my PC I tried flashing but not sending the img files please help
As the title states, I cannot get it to work. Yes, I do have root and my bootloader is unlocked. I've already tried modifying the boot.img and system.img both but to no avail. If anyone out there smarter than me can help that would be greatly appreciated.
If it helps, im on the OG Pixel.
Having the same issue (on the same build, with the same phone). Stock Android + Magisk. Trying to modify my build.prop so that I can enable tethering. Can't figure out how to mount /system as RW (only able to get it mounted as RO). I even tried doing it from TWRP, but for some reason, it won't mount system unless I check the box for "Mount System as Read-Only".
EDIT: Oh and I should mention, I also tried from adb shell.
sailfish:/ $ su
sailfish:/ # mount -o rw,remount -t ext4 /system
'/dev/block/sda33' is read-only

I wanted to delete some files from the system like some useless system apps/themes etc. I was trying to root my phone with magisk. The magisk would install but I couldn't make any kind of changes because I found it was read-only! Now if I want it to mount read-write, it just won't. Any solutions, anyone?

Try this script from this thread.
You can't mount system because of dynamic partitions (super partition). The script linked above doesn't mount system rw, it just makes a new super partition.
The real way to make edits to dynamic partitions is with adb remount which replaces the old 'mount -o rw, remount /system' method.
The practical way to make edits is systemlessly with a magisk module.

I feel superdumb but @jwchips , where am I supposed to put those commands- in custom recovery terminals, in Windows command prompt or in a terminal emulator app?
Plz someone teach me step by step. I can't rw system by root explorer in miui rom, but I can do it in aosp rom. I don't know what causing this result. Since android 2 to android 11. Every upgrade time I struggle a lot. Now I spend 2 mouth to search internet but for code noob like me, get nothing. I'm still study it hope a newvice tutorial post.
same problem here, ive tried different zips and also doing it manually, no success
