I cannot write to my phones system partition. I can successfully run
Code:
mount -o remount,rw /system
from the shell but doing
Code:
mount | grep system
afterwards reveals that the partition is still read only. Root apps like Link2SD and ES File explorer also fail to write to system. I can still do it from inside of TWRP but I'd like to get it working in Android. Is there any fix for this as of now?

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, i've been trying to mount my filesystem as RW, but all the commands that i searched failed! Can anyone enlighten me?
commands i used:
Code:
ADB Remount
and i get operation not permitted
Code:
ADB shell
su
mount -o remount,rw ext4 /blah/blah/blah /system
this works, but i cannot push files from my mac to the phone! OMGOMGOMG.
Might be easier to use Root Explorer. It's basically a file explorer that lets you make system files rewritable.

Yeah in the end i succumbed to UI and used ES to do it. But i wanna understand what went wrong! So someone, please tell me!
[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/sharе
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
But you cant use any OTA updates because your download /cache folder filed now. Remove all before update
rm -R /system/share/*
rm -R /cache/*

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.

Looks right to me.
Thanks for the info. I am learning to love my M more and more.

I cut and pasted this exactly and it doesn't work. Can you please reply with exact sequences. I keep getting mkdir failed for /cache/your-program-folder, File exists
Will this work on a bionic?

SM-T705, cf-autoroot (incl. SuperSU) checked with root-checker, platform.xml adapted
e.g. if I want to copy /dev to my sdcard ... there comes a message similar to "copying went wrong ... 4.4+ .... in non-root mode some limitations ..."
I won't search for you, please have a read through Q&A and General for a number of other similar questions and corresponding answer I would suggest you please contact a Mod to delete this unneeded thread
Sorry I searched and read a lot of older suggestions but did not get a clue ... and I know about the kitkat probs regarding SD (platform.xml). But still dont understand, why there are just few folders affected ...
So sorry but it seem I need a Little push into the right direction
+1 solid explorer has struggled for me, but root explorer hasn't. Seems to be only certain directories. ...idk
just to make shure - we are talking about Root Explorer (File Manager) non free app. Did you try to copy System dirs like /dev ??
if yes, where to did you copy them. I just figured out that my ext3 partition (1st=exFat, 2nd=ext3) on the SD is mounted to /data/sdext2.
but copying /dev to /data/sdext2 doesnt work either
Could someone please tell me how to Mount /mnt RW
some folder cant be copy. the only way for you to have those are extracting it from the original firmware.
THX - 2 Pprobs now
1
mount -o remount rw /System worked, but still
[email protected]:/ # mkdir /mnt/extSD2
mkdir failed for /mnt/extSD2, Read-only file System
a) with Root Explorer it seemed to work, but was gone after restart ?
b) where to mount my ext3 SDcard partition (1st exfat, 2nd ext3)
c) can I do it by modifying init.rc, universal5420.rc or fstab.goldfish ...
2 how to extract Folders from Firmware files like T705XXU1ANF7_T705DBT1ANF1_T705XXU1ANF7_HOME.tar
I extracted the files within. But how can I Mount those Image files on W8 (ext2fs does not work with my sdcard) ?
2nd best would be to go to my Linux PC (but I'm a Linux DAU) ...
try learn about kitchen or use this software on windows... ^_^ http://sourceforge.net/projects/ext2read/
sorry my english is not good enough ... kitchen seems to be a Linux tool ... this seems to be a good start http://www.modaco.com/topic/366230-tools-useful-tools-for-tinkerers/ or this http://www.diskinternals.com/linux-reader/
Best use OSFMount to Mount the *.img and "Paragon ExtFS for Windows" to view the files
mount -o remount rw /System worked, but still
[email protected]:/ # mkdir /mnt/extSD2
mkdir failed for /mnt/extSD2, Read-only file System
a) with Root Explorer it seemed to work, but was gone after restart ?
b) where to mount my ext3 SDcard partition (1st exfat, 2nd ext3)

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!
