Alright, so I've been trying to mount the /system partition as rw today now that we have perm-root and I've been failing. I'm tried multiple mount options such as
mount -o rw,remount -t ext3 /system
mount -o rw,remount -t ext3 /dev/block/mmcblk0p15 /system
and a few others. The command works but when I try to uninstall an application via the package manager:
pm uninstall /system/app/amazonmp3.apk
pm uninstall /system/app/amazonmp3
I get failure.
I was also searching in the init.rc scripts in /, and noticed that it mounts the /system twice. Once in rw and then again in ro. I can't change that file though since for whatever reason, I still can't access the /system even with perm-root (s-off).
Titanium Backup also doesn't detect any /system applications.
Any thoughts, or enlightening clarifications? I'm not a Linux beginner and have experience in system administration all the way from Debian Sid to Arch Linux.
EDIT:
Solution: I have ro.secure=0 now and the remount is now successful.
You are using the pm command incorrectly. The argument is package name, not file name.
pm uninstall com.amazon.mp3
pm list packages for a full list.
That would be the reason. Unfortunately I can't look at the man pages of these commands on the phone ;D.
You edited your post to show that you now have r/w access to the /system folder, but you didn't say how you achieved ro.secure=0.
Care to share? I'm having the same issue.
perm root will give you ro.secure=0

rosecure=0 is set in the ramdisk of the kernel. It allows easy mounting rw , as in adb remount, however shouldn't be needed. Use this to mount as rw:
# mount -o rw,remount /dev/block/mmcblk0p25 /system
Replace rw with ro and run again when your done to return system to ro. I just tested it and it does mount as rw
Just to make sure it worked, I type that and get:
Usage: mount [-r] [-w] [-options] [-t type] device directory
after trying this.

U sure you typed it exactly as I did?
There is a space after /dev/block/mmcblk0p25 before /system
Edit: and no space between comma and remount as in rw,remount
Yeah, that's how I typed it, exactly as you had it =\

Hmm, and you did this from root prompt # not $.
Can anyone else confirm or deny that command for me. I'm gonna flash a unmodified kernel when I get home tonight and see if that makes a difference.

I can confirm it doesn't work on my G2 either. I'm using Cyanogen RC1 btw.
try
mount -o remount,rw /dev/block/mmcblk0p25 /system
maybe the rw has to come after remount.
Anyways, I know mine works on permrooted stock
That did the trick, thanks!

So weird. If I type it that way, I get the mount options menu u were getting. If I type it my way it works.
I was messing around with remounting the /system partition with rw permissions, and the thing is that it does work as in, it doesn't give you an error when mounting, but it still doesn't let you access it. It's weird.
As for the ro.secure, I just used installed bacon bits, and it did it for me.
There's an app for that! I'm using a market app called mount /system (rw / ro). You can just search mount rw in the market, its free too

Can't you just use adb remount?
It worked for me (GT-P1000, CM 10.1-20130218-experimental- cdesai)
First, my Euro Desire Z is S-Off (using the gfree method) and perm-rooted.
I was messing with installing some new keyboard layouts to the /system folder, when I found and installed busybox from the market to use its cp command...
Then I discovered I could no longer write to /system -- I could before busybox
I booted to recovery, installed my nandroid backup (taken before installing busybox), and I still can't get write access to /system
I did a factory wipe (still have S-Off) ran visionary to root and permroot ( I get the # prompt just fine) and still no write access to /system.
I restored my nandroid to get my apps back and still can't seem to get write access.
Any ideas
Hmm -- I just found and installed "mount /system" from the market and that did it -- I can now write to /system.
Not sure why it stopped working before... Busybox may have been a red herring.
I think it was just that you still had /system mounted as read-only, and that app just mounted it as read-write (i.e. "mount /system -o rw, remount" )

Yeah -- I had it RW and something must have remounted it to RO --perhaps when I was doing an adb session...
Speaking of BusyBox -- whats the best version people are using for the DZ?
Hi All,
Can some one please suggest me a replacement for root explorer? I tried to run it on Moto ginger 2.3.4 but getting a force close.
How do you guys copy files to system or other protected directories? I tried adb remount but its failing for permissions issue.
You have to use root explorer v2.16
I use Yaffs Explorer. It's very nice in that it uses a small font for both file lists and the internal editor, so you see a lot of content on the screen.
As for ADB, do an "adb shell", then you can gain root by typing "su". On the phone the usual superuser popup will appear, confirm it and voila you have root in the adb shell. Then you can remount with "mount -o remount,rw -t ext3 /dev/block/mmcblk1p21 /system". And to go back to read-only: "mount -o remount,ro -t ext3 /dev/block/mmcblk1p21 /system"

Great!! Ill try that.. Thanks..
Also you can try Super Manager 2.2.9, it's free and it's pretty good.
[Tweak root] add extra +700mb to Internal memory storage from /cache & +600-900MB from /system folders.
just run terminal with root & paste code
su
chmod -R 777 /cache
mkdir /cache/"your-program-folder"
mount -o bind /cache/"your-program-folder" /storage/sdcard0/"your-program-folder"
add extra +600mb (+900mb if you have LiteRom) from /system folder.
su
mkdir /system/share
chmod -R 777 /system/share
mount -o bind /system/share /storage/sdcard0/sharŠµ
before you can write to /storage/sdcard/share mount it RW
su
mount -o rw,remount /system
after every reboot do it again. how add script to startup folder, any Idea?
all work great. I have 4.5GB + 700MB + 800MB internal storage for my music and maps.
But you cant use any OTA updates because your download /cache folder filed now. Remove all data before update
rm -R /system/share/*
rm -R /cache/*
Re: [Tweak root] add extra +700mb to Internal memory storage
Are you sure you got these commands right? And why don't you just make a script to automatically run these commands at boot? You know, so you don't have to keep running the commands over and over? And you have the work "program" spelled wrong. Its spelled with only 1 "m". Program, not programm.

So what happens if you are using your whole internal sd including this 700 megs and you reboot? Does the system freak out?

absolutely right. And why don't you just make a script to automatically run these commands at boot?
How, do it, init.rc not work.

everything will be fine, just live little more space on /cache (100mb at least)
UPDATE 1st post. add extra +600mb (+900mb if you have LiteRom) from /system folder. Now I have 6GB internal storage for my music and maps.
su
mkdir /system/share
chmod -R 777 /system/share
mount -o bind /system/share /storage/sdcard0/share
before you can write to /storage/sdcard/shear mount it RW
su
mount -o rw,remount /system

Well, make a new folder on your sdcard, I used root explorer. I called it "67tweaks", I then zipped up the folder, then navigated to my zipped folder and I removed the .zip extension (doing it this way allowed me to make a new text document, but theres prolly an easier way, but this is the way i used) and then I long pressed it so it would let me open it up as a text document. I deleted some jibberish that was inside, I then started with #!/system/bin/sh, then space, then pasted your commands under the space and I then placed the file under system/etc/init.d folder. Now every time I boot up, the script gets run. You can also use an app like "ROM toolbox" and go to scripts and just create a new script and select it to run at boot, or you can use SMmanager and create a script to run at boot.

I'm no dev so I wouldn't be able to make a script to run at boot, but if you don't have init.d support you can add a script to your init.qcom.post_boot.sh file in system/etc folder and it should run at boot.

Hello everyone, I've been using android since Eclair and I had a couple of different brands under my ownership. Sony Ericsson, Samsung, Alcatel...
I've always been rooting my phones. After that, each time I needed rw privileges in order to be able to delete files (like built-in apps), place ringtones, alarms and notifications sounds directly into /system/media/audio, rename or backup system files etc., I was using a simple command from a terminal app or via ssh from a desktop giving this syntax:
mount -o remount, rw /dev/block/mtdblock3 /system
Then, until next reboot I could write in /system.
Unfortunately since I got G3 this command won't work. Apparently, either lollipop's or LG's partitions are a bit different that the usual...
After looking around for a while, I came up with a page which shows that this command "ls -al /dev/block/platform/msm_sdcc.1/by-name", lists all partitions' paths by label and that according to the list, /system corresponds to mmcblk0p40. So I was thinking of trying the command a bit altered, like this:
mount -o remount, rw /dev/block/mmcblk0p40 /system
Since I don't have good knowledge of linux -I can't even tell if the old syntax is not working because of LG's implementation or of android's new version (lollipop)- I'd just like someone who has already done this to confirm that I'm right and it works. I'd really not like to brick the phone atm. I feel too old for this s...
Thanks, George...
P.S.: Now, if someone would be kind enough to provide an in-depth explanation of how I could always find by myself (in any newer version of android and any different android implementation), which partition is the appropriate one to use in this command in order to obtain rw for /system, that would be more than welcome!
Edit: I should have mentioned this to avoid getting answers about 3rd party apps which do those stuff like root explorer: I'm looking for a solution, not a workaround. I need the syntax of the command, not a list with apps which do what I'm trying to do using terminal. But thanks adamzki anyway...
Use root explorer pro. That's it.
This command is enough to mount /system as rw;
Code:
mount - o rw,remount /system

That's really strange, I had used "mount -o remount,rw /system /system" and it didn't work
I now used "mount -o remount,rw /system" and it works! I'll never understand Linux...
Thanks anyway man!
