Soory for very delayed reply, i never had trouble with sms, so i have no solution.
The way for making system as read/write;
Code:
mount -o rw,remount /
mount -o rw,remount /system
(Note: it technically should work, but i have not tried on this device)

that code won't work on android 9 and above

Search forums for super_rw v1.32
Super partitions need to have their blocks removed first and that script does it for you, then just flash the new super image it produces.
Used it on my C3 and c21

[Q] About Removing System Apps

I have rooted HTC Desire and i tried to remove system app in many ways but nothing worked. Pls give any advice how can i done this.
First i tried with Root Explorer, i mounted R/W mode i deleted the app, the app is deleted from /system/app but present in menu and when i restart the phone it comes back in /system/app
Second i tried with Terminal Emulator: "#mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system" "#rm /system/app/appname.apk and i got the same result again :\
Third i tried with Titanium Backup Pro, when i Uninstall the app i got the same result but when i try to freeze it that's the only way i can remove from the menu :\
Thanks
Root Explorer only works if you're S-OFF
Easiest way, download the Android SDK and use adb in Recovery to remove them
Remove the apps from the ROM before flashing it?
Be carefull as removing certain apps can make the ROM unstable.
Sounds like the OP has only rooted and isn't using a custom ROM, hence my suggestion
Otherwise, yes, download a custom ROM and remove what you don't want prior to flashing

I've recently come across two very interesting Windows apps which make the process easy.. Android Commander and QtADB...Both are GUI frontends for ADB, so once rooted, removing it should be easy in these. However, I believe that some may be removable only in Recovery mode, unless you have S-OFF
My devise is rooted and i use custom rom, Oxygen 2 atm but its not S-OFF, how can i S-OFF? I used unrEVOked to root my phone.
Thanks

Did you boot to clockwork recovery first? You must and then run
adb shell
mount -o rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/app
ls
rm anythingyouwant.apk
rm anythingyouwant.odex
mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
reboot with trackball
This is how I do it in linux. You can boot with live distro linux, connect your desire and start console. I think it should work. I do it from virtualbox.
Thanks alot, S-OFF was the problem, my phone was rooted but not S-OFF. Now everything is fine.
Thanks,

[Q] Correct path in Terminal Emulator?

I have spent hours trying to find an answer to what I thought was a simple question, but I just can't seem to find it...
I wanted to familiarize myself more with Terminal Emulator, so I used it to delete a system app that needed to go.
I used these commands:
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblk3 /system
# rm /system/app/xxx.apk
It appears to have worked perfectly after a reboot, but my question is: what is the correct code to mount your system partition in TE? I have seen several variations of the line I used. Often they vary at 'mtdblk3.' I have seen it 'mtdblock5,' for example. Is there a particular line I should use for my specific device? Is it dependent on what I am specifically trying to do?
Any information is greatly appreciated; even/especially a link toward my answer. Thank you very much.
I've always used 'mount -o remount,rw /dev/block/mmcblk0p25 /system'
as far as 'correct' code I don't think there is as such. But I think different devices would have different partitions and mount points for system.
-Nipqer
I think it will depend on where your system is mounted, although I don't know why that would vary for the G2. It might be different for the DZ and certainly for other devices.
You can type "mount" in the terminal to see where everything is mounted.

i use this command:
# mount -w -o remount /dev/block/mmcblk0p25 /system
Thanks for the replies... I see now, that the path I should have used is: /dev/block/mmcblk0p25 /system. And that "code" was the wrong word. I was asking about commands & paths not code. Sorry - still learning.
edit: If anyone knows of a good and thorough resource of Terminal commands, I'd love it if you'd share... I've found bits and pieces of info, but something more comprehensive would be great. Thanks again.
Wow you guys are going about it using the long hand method. If you're just deleting a system app, to mount the /system as rw just enter:
Code:
$su
#mount -o remount,rw /system
#rm -f /system/app/xxxx.apk
The -f command isn't really needed but I use it to make sure the job gets done. Not sure if the pm uninstall command is used anymore. I'll have to look into that. I know some phones required you to mount yaffs and mmcblockXX but for just deleting an app I don't believe it's required. Never had an issue not typing that.
Here's the correct way to delete the app:
mount -o rw,remount /system
rm /path/to/app
reboot

Or you could use remount,rw. It's the same command. I threw reboot in there to reload the app list in your launcher correctly.

adb mount command for rw on Tab Pro

Just got a used Tab Pro 8.4. I've rooted it and now am interested in debloating it. I've always done this manually with adb on my previous devices using a command I always assumed was specific to that particular device (ie. mount -o remount,rw /dev/block/mmcblk0p20 /system for a Note 3) .
I haven't found any references in the Tab Pro forum to the mount command for writing to the system partition. When I list the mount points with the mount command inside the adb shell I see this:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0
So would the command really be mount -o remount,rw /dev/block/platform/msm_sdcc.1/by-name/system /system ? I have seen references elsewhere to a generic "mount -o rw,remount /system" command for Android devices in general.
I'm sure there are pre-built tools that would let me do some debloating without worrying my little head about what's going on under the hood. But please humor me. I enjoy learning the details of how these boxes operate by working with them manually. Any help here will be appreciated. Thanks.
So you are not going to flash the ROM, you could also try Gates Debloater tool. I used on my Note 4 all the time, may Tab I just flashed to a new ROM though.

No thank you. I like to see the .apk disappear when I delete it from the command line. Just a thing I've got. I assume I'm looking for something like "mount -o remount,rw /dev/block/?????? /system".

If it's rooted you can use titanium backup to delete.

All you should need to do is
# mount -o remount,rw /system
It's in fstab, so you don't need the block device.
When done just issue a sync and reboot.

System remount?

Has anyone been able to remount /system as rw? FX File Explorer says it's successful but then switches automatically back to read only
I'm also trying to remount /system as rw. It seems that the patched Magisk boot file provided in this post preserves dm-verity, which disallows system partition modifications and makes it unable to remount as rw. The mount command will complain that '/dev/block/dm-8' is read-only.
Having tried repatch the boot image with unchecked 'preserve AVB 2.0/dm-verity' in the Magisk app, but resulted in a crash during boot (QUALCOMM CrashDump Mode). Can succesfully boot with that option checked. It would be fine if dm-verity can be disabled in other ways.

Have you tried fastboot?
fastboot oem disable_dm_verity
If it causes problems, replace disable with enable to get back to current state, but it shouldn't
I don't like to disable dm verity for performance concerns, but for now it would be okay until a new root method comes out

Correct me if I'm wrong,but devices released with Android 10 out if the box will not allow making changes to the system( i.e it will remain read-only only)

Why? What error do you get?
Try to move/copy something into /tmp folder. It should work if you're rooted (your shell shows # instead of $).
If it doesn't work, maybe you have to remount your system as rw (read and write):
Code:
mount -o rw,remount /
after you made your modifications, mount it as ro (read only) again:
Code:
mount -o ro,remount /
If it still doesn't work, we need to see the error you get (copy and paste into this forum) while moving/coping something into /tmp.

Can you verify you entered that command as root?
Please do the following:
Do this on your computer to enter your devices shell
Code:
prompt_PC:~$ adb shell
Code:
prompt:~$ whoami
This should give you either "shell" or "root"
If it says "shell" do:
Code:
prompt:~$ su
prompt:~#
It will show a # instead of $ if you're root.
If you're already root (or you are now root due to su command), do:
Code:
prompt:~# mount -o rw,remount /
Now it should be writeable and you can do your modifications.
After you finished you need to change it to ro (read only) again:
Code:
prompt:~# mount -o ro,remount /
After that you can exit the shell:
Code:
prompt:~# exit
prompt:~$ exit
(first exits su, second exits shell)
I'm sorry if you already did that but I wan't to be sure you did it correctly.
If this procedere doesn't work, please copy and past your input and output into this forum as this might help to understand what's going on/failing etc.
