System write failed after root

Hi,
i rooted my mate8 succefully, but i can't modify files on root/system
I tryed to modify build.prop but i'm not able to save
I used mx explorer and grant proper permissions on super-su .
The root is applied ( checked with the cecker root application)
Any suggest?

Remount system as read/write, that usually isn't done automatically.

Help with read-only and /vendor

Hi!
I've been trying to boost my volume with changing values in mixer_volumes_FRD_ce with both solid explorer and with root browser. But I always get the same problem and the problem is that it says I can't do it in read-only mode but when I've booted into twrp I've deselected the mount system as read only. Another problem is that I can't change values in the under mixer path because it says I can't do it under /vendor... I'll gladly take any help or suggestions ... Stock rom btw

I don't know about the last part but if you are using some kind of system explorer you must enable r w (read write) in it.

I'm rooted, trying to install Xposed Framework, how do I delete a file from /system/?

I tried installing it with both Flashify and Magisk, but both methods failed.
When I tried installing it via the included Xposed Installer, it also failed, but gave me the message:
> Error: Xposed_Framework.jar already exists in /system/framework
I'm guessing a previous installation failed, but left the file there.
My next idea is to delete that file from /system/framework and try again, but since it's in an RO directory I don't have permission.
I tried using a terminal emulator to mount the drive in rw mode, and also tried using a root file explorer, but either both methods don't work, or I just couldn't figure it out.
Anyone have an idea of how to remove or rename that file so I can try to install the .zip ?
-Thanks

In the Xposed app you should be able to just run the uninstaller script. If that doesn't work, boot TRWP and delete it from there.

Unfortunately, the uninstaller also fails.
It says it can't remove that file from a read only directory..

Root Explorer....
This app does wonders, it allows you to modify directories in /system and other root folders. You can even change permissions of specific folders/files from read/write/read-only....etc. I've had this app since the earliest of android days and it has been my go to file explorer. Root Explorer of course requires root....but it completely unlocks your phone and allows you to modify any system file that is set to any permission. Of course there are other file explorers that allow you to modify system files, but this is the one that i have the most experience with. You should be able to access the system folder where the Xposed file remains and modify it so it can fix your problem.

This!. I've used it for years. Not muss no fuss. It's not bloated like a certain couple others I know of. It just does what it does and does it well. Manages files. No extra garbage.Give it a try. I'd be surprised if you can't delete it with Root Explorer. If you do try it, go to the folder you want to delete the file from. Once in there, look at the top right of the screen. Somewhere up there It will say MOUNT R/W. Touch that and you should be able to do whatever you want to within that folder.

Do you have the magisk DNSCrypt module installed? If so, thats why you cant modify anything in /system. Not sure why or how it breaks it, but it does. Took me for ever to figure out what was causing it. Now that i removed the module, i can modify anything i want again.

Can't edit or replace files in /System/~

As the title says, i cant edit anything inside /System, no file explorer works, every single one of the says that the operation failed. I wanted to replace the boot animation and some UI sounds, tried flashing the files with recovery, no luck. Other root things works as intended.
Rooted quad-core Shield Tablet, Android 7 stock, busybox installed, also Xposed with greenify.

Question I can´t remount /product read-only partition

I did a search for an answer without lucky.
I have the latest 12.5 stock rom, rooted...
I just want to install Vanced Youtube and it always show me an error saying that I can´t downgrade.
The youtube app is located in /product/apps/youtube, but I can´t delete using an rooted explorer nor in twrp, nor adb.
I tried to remount /dev/block/dm-2 in /product but it keeps saying that it´s still a read-only.
Also tried to disable-varity, but this time the message is that I have a User build.
Any ideas?
Can´t uninstall Gmail or any app located on /product
