So ive upgraded to 2.1 Via nordic method but ADB doesn't seem to work. It worked for one time after I upgraded and I removed some useless stuff such a moxier and stuff but now it doesn't really work. ADB pull works fine but when I try to mount the device with "adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system" it says "mount: Operation not permitted" and when I try to remove more files I get something like the file is read-only or something.
Same problem overhere.

If you just type ADB SHELL, do you get $ back?
Then SU, get #
Do you Titanium, Busybox and Superuser working OK at the phone?
I am trying to root an elocity A7 and I pretty new at this. I installed root explorer but the mount r/w button does not work in the system folder. I tried the terminal command below but it does not seem to accept the command. I get back a message that says shows Usage: mount [-r] [-w] [-o options [-t type] device directory. I retried root explorer and still can't write. Thanks for any help.
- open Terminal emulator:
$ su
# mount -o remount,rw /system
- open Root Explorer \system folder and press r/w
adb remount
or search the market for "mount system"
I'm not following how to use adb remount. What would be the complete command line? Also, I can't get to the market which is why I am trying this. I read it on another thread here.
i cant find mount r/w button
download this program from the market "Mount /system (rw / ro)"
I can't get to the market on this device. Any other way of getting it?
Try the attached zip
Thank you! That worked.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
Thanks For the App Recomendation

my rom is stock but got a version that used zpst to force magisk to allow root, root is good but cant move 1 app to system without read only i tried this it says it worked but when i try to move it says i dont have permission .. guessing there isnt a recovery for this model the z835
I thought I'd bricked my NT but it would appear that it is actually alive because it turns up with adb and I can get shell and then issue command su, but what I can't do is replace the old build.prop because file system is not writable. How do I remount it to be writeable from a shell please?
Thanks!

mount -o rw,remount -t ext4 /dev/block/mmcblk0p8 /system
Type mount to verify rw, make your changes
mount -o ro,remount -t ext4 /dev/block/mmcblk0p8 /system
Type mount to verify ro
Thank you!

I don't have this tablet but a phone with similar problem.
this does not work for me, although I have ROOTED phone MTK6572, android 4.2.2 ;
"/ root" gets RW, but "/system" stays RO.
I get this message:
error
"the item "system" is read only"
I have tried many apps in phone (remount system RW, FX file expl. ....), and mtkdroid-tools and ADB shell in PC.
I have tried many similar version of that command, too, inc. busybox remount. non of those work.
any ideas, what to try next?
what file or thing or item and where I need to change to get this remounting system to RW done?
it is ext4, and remountable.
I have SuperSU in phone but can't update its binaries: /system stays RO, what ever I try...
I can't change audios, anything in /system.
very annoying...

I understand your frustration, however, you should try to post your question to the MTK6572 or Samsung S4 thread. Anyway, since you have asked I'll answer. The mount point for /system is different on each phone model. There is no one standard /system mount point. On the Nook Tablet and Nook Color it is mmcblk0p8. On your device it is different, so the command you tried will not work.
You need to find out what the /system mount point is for your phone.
Open terminal from phone and type su.
Press enter.
At the # prompt type cat /proc/mtd
Press enter.
Look at the output on the screen and see what the mount point is for /system.
A the the # prompt type mount -o rw,remount -t ext4 /dev/block/enteryoursystemmountpointhere /system
Note: replace enteryourmountpointhere with your mount point from the previous step.
Change /system to ro when done. Hope this works for you.
Also download root checker app to ensure you rooted properly.

thanks for your responce.
with that "cat ..." I got : "no such file or dir"...
I know already that my mnt point is (did try already these earlier):
mount -o rw,remount /dev/block/mmcblk0p4 system
mount -o remount,rw -t ext4 /[email protected] /system
but no success, " system read only" stays, and no change.

Did you use the root checker app to verify for proper root?

yes.
I have many apps (e.g. FX, ATools, TitaniumBup, busybox, ES, mount /system rw, SD maid, root expl., adbd insec., rootAppDel, a.s.o.) that use root rights, and phone's superSU gives the rights to them.
AT:s terminal has # prompt, so it must be root. (?)
adbd insecure's current status = binary: insecure; usb debugging: enabled.
I have earlier version SU's binaries working ok, but updating SU made this binary-update-issue: " binary update failure" and so SU-app won't open (it closes after failing binary update), though otherwise it works ok (and worked earlier until I did let G-play to update it, silly me!).
somehow my /system has been "open" i.e. RW earlier, since busybox and superSU has been installed, but now it is "stuck" to that RO-status. "/" opens, but "/system" not.
MTK Droid Root & Tools v2.5.3 (from here xdadevs) gets root shell ok, but fails when trying to install SU, busybox a.s.o. ("read-only system") - and it "crashes".
maybe kernel related? or boot loader, or .... what?
-----
btw, my apologises, that I wrote this issue to this thread, but I found my "problem" here with the search, and after posting I realized that this is "tablet area..."
so this part can be moved to better place by those who know best where to - though not to trash, anyway....

Don't know what else to suggest, except maybe contact Chainfire on G+.

I just installed Android Q and was trying to mount the filesystem as RW in Android Terminal.
When I run:
su
mount -o remount,rw /system
I get an error that says '/dev/block/sda33' is read-only
I tried an app from the Play Store called "Mount /system RO/RW" but it didn't make a difference
I was just wondering if there is a solution yet for this?
Same issue, have not been able to rectify it.
Hello,
im new here and i rooted my OP 5t and it still works. But when i want to make another app to an System app i always get this Error : "mount: can't find /system in /proc/mounts".
I tried it with Link2SD or Terminal Emulator but nothing works.
Can somebody maybe help me with this problem ?
@N3xus97
Try
Code:
adb shell "mount -o rw,remount /system"

I already did this but it doesn't work for me.
But there is a password on the TWRP is it possible that this cause the error ?
@N3xus97
Don't know because I'm not using TWRP.
BTW: /system isn't a mount point.
