I can`t make /system go rw

[Fireintie]

I just wanted to change a line of code to make my xposed work for my android 4.4.2 on Honor 4x. I realised that i need to mount my /systen rw... but i can`t do that!

I tried tons of commands like:
mount -o rw,remount /system
mount -o rw,remount -t ext4 /dev/block/(here tons of other endings) /system
mount -o rw,remount -t yaffs2 /dev/block/(something) /system

And it always said:
mount: read-only file system
225|root@hwChe2: / #

Because no commands ork for me .I wonder if it has something to do with kernel...

(And yes - I used su command - u can see that by # sighn)

Welcome to AF, @Fireintie!

Does the Honor 4x have an unlockable bootloader?

That might be the reason that you cannot remount /system in read-write mode...

Your commands look okay to me, but if you could provide the output of a full mount command or (better yet) a "mount | grep /system" that would be helpful (that still doesn't mean you'll be able to get it to work--I'm just trying to verify that your mount command attempts were correct).

Here you go:

root@hwChe2:/ # mount | grep system
/dev/block/mmcblk0p38 /system ext4 ro,seclabel,relatime,data=ordered 0 0
root@hwChe2:/ #

And yes - i found some tutorials in the internet about unlocking boot on honor 4x so i suppose it is unlockable

One more question (that I think I know the answer to): does your device have SE Linux set to enforcing?

If so, it's likely the remount of /system is not allowed in the context that the mount command is being used (launched) in...

When i write getenforce it shows: Enforcing
Should i change it to permissive?

Btw. Sorry for not responding so quickly as u do

Oh, no, don't change it...that just tells me that your system might be also enforcing the write-protection on /system because of SE Linux's policies.

You might be able to try invoking the mount command via su with a special context that might work:

su --context u:r:init:s0 -c "mount -o remount,rw /system"​

It's a bit tricky to nail-down which context will work...the above works on my Nexus 5.

Your code does not work for me... you said that it might be diffrent... can you tell me how to try diffrent combinations? What to change?

Can you r/w system with ES File Explorer, Root Explorer etc? If not, you may have to unlock your bootloader as Scary Alien mentioned earlier. I'd go with DC-Unlocker for your Huawei. I've used it on a handful of different Huawei devices with success. Never a bad idea to get unlocked - surely there must be a custom recovery out there for the 4x by now - then you can back up and prevent future issues from messing about in /system and elsewhere.
