Read Only File System after Rooting

[vulcanY]

When I rooted my device , Redmi Note 9 MIUI 12.5.2 , It gave me all root privileges except an error of " Read-Only File System " .

I can change some system files, but some files Can't be changed or deleted or edited anyway.

I wanted to change the Boot Animation, so I took a zip file and deleted the boot animation.zip from system/media , but as soon as I delete , somehow it magically gets restored. I am not able to overwrite that file.

I tried to install magisk but it shows read only file system . I did also try mount -o remount commands , but Nothing works.


Please help me in this situation!!

You cant mount system as read-write.

Try this:

[SCRIPT][Android 10+] Universal Mount SystemRW / SuperRW featuring MakeRW (read/write)

If you can't get this script to work on your device check out the brand new sophisticated superrepack tool by @munjeni line SystemRW / SuperRW (feat. MakeRW) v1.32 by lebigmac NEW VERSION COMING SOON! STAY TUNED!;)(y) ANY TALENTED DEVELOPERS...

Could you please tell me how to do it. I've tried " mount -o remount,rw / " but even after doing so, I wasn't able to install magisk

I said you can NOT mount system as read-write.

Hi @VD171 @vulcanY
What do you mean system cannot be mounted as rw on your Redmi Note 9 ? Does it have shared_blocks read-only feature? You can check like this

adb shell
su
tune2fs -l /dev/block/dm-0

What about the other partitions? /vendor , /product, /system_ext, /odm? Same problem? I know /odm can sometimes cause trouble...

If you're lucky next version (which is coming very soon) might do the trick but I can't 100% guarantee it yet

This is the Output of that command

Well it looks like my script successfully removed the shared_blocks read-only feature from your device
Unfortunately you still have read-only error for some reason. There must be additional protection features enabled on your device. To find out more info about your specific read-only error you can run dmesg immediately after remounting your partition as rw like this:

adb shell
su
mount -o remount,rw /
dmesg > /sdcard/dmesg_output.txt

 

[vulcanY]

Again After remount it shows Read Only Error and here is the dmesg_output.txt

Your dmesg looks really long.
Try to reboot the device, mount as read-write and then save dmesg output again.

Even after reboot, the size is same
