I tried copying files to the system folder but I keep getting "failed to copy, out of memory". Any idea why? I also tried using Root Explorer but despite the pasting animation being displayed, the files were not copied.
I've tried both the terminal emulator
Code:
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cp /sdcard/libt9.so /system/lib
and adb
Code:
adb remount
adb push lib/libt9.so /system/lib/libt9.so
It seems the file has been moved successfully through recovery mode, but I still can't see the file when the phone is booted.
i rooted my verizon galaxy tab and i can run Root apps, but i cant move a wpa_supplicant file to my /system/root using Astro.
Is this a root issue or do i need something better than Astro? I also tried OI file manager but it just says "cannot move file here".
By default, /system is (usually) mounted read-only. You probably need to remount it read-write.
Code:
adb remount /system
adb push [path-to-file] /system/bin
If remount doesn't work, try
Code:
adb shell mount -t yaffs2 -o rw,remount /dev/block/mtdblock3 /system
my atrix 2 was rooted and everything was good. a few days ago I copied a new su file using "Absolute System root toolbox" from sdcard to /system/bin, now i am still struggling to find a way to change the permission of the su file. looks like it's locked as a read-only file, now I can not use root explorer to change permissions of files or folders, and on my laptop using adb it gives me a $ rather than a #, it reads "operation not permitted".
any clues? thanks in advance!
**One quick note** If you got the 2.3.6 update, zerg doesn't work. In that case you will need to wait for a new root method to be made available.
This comes from the rooting thread in the dev forum. None of it is my work... You need a root shell to reset the permissions on su. Here are some instructions that should allow you to do that.
Download exploit ---> Exploit.zip
1) Unzip contents of folder to your Desktop
2) open a command terminal and navigate to the folder (cd Desktop/Exploit)
3) type the following commands
---> adb push zerg /data/local
---> adb shell
---> cd /data/local
---> chmod 777 zerg
---> ./zerg
4) Wait for the root to be gained
5) type the following commands
---> adb shell (only type this if you are no longer in [email protected])
---> mount -o rw,remount /dev/null /system
---> chmod 4755 /system/bin/su
Hope this helps / works...
Yeah you basically need to re-root your device.
i am trying to mount /system as rw, but keep running into errors. my tab is rooted and i have superuser elite installed. i have tried from a terminal app from the su prompt (#mount -o remount,rw /system and variations of), from adb shell, and using adb remount, but always get an error. (permission denied, are you root?)
any suggestions?
secondly, i messed up my permissions on both /system and /etc, as i had a similar issue with permissions when i was trying to get root, but forgot to note what they were previous so that i could set them back. i set them both to 755 for now, but if someone could tell me what they are suppose to be that would be appreciated.

Hi,
Try :
adb shell
su
mount -o rw, remount /system
It work fine for me on adb shell and terminal emulator
The command adb shell remount doesn't mount /system as rw
thanks, that put me on the write track. turns out i was getting rw the whole time, but i didnt have write permissions. did chmod 777 /system and it worked, and when i was done i put it back to chmod 755 /system
if anyone has a similar problem, the command 'mount | grep /system' is a great way to check to see if you actually have it mount as rw or not.
before this i tried a couple of the remount apps, as well as the mount as 'rw' option in es file explorer and they always fail to mount, presumably they aren't failing to mount but are running into the same permission issue and can't write
i want to use INT2EXT in cm9 i followed this tutorial

INT2EXT+ INSTALLATION TUTORIAL
IF YOU ALREADY HAVE S2E, LINK2SD OR SIMILAR, YOU MUST REPARTITION SD CARD AND FACTORY WIPE
int2ext+ is a relatively new script that instead of making symbolic links(Link2SD) or moving certain partitions(S2E) to sd, extends your internal storage into your ext partition in sd, which means S2E's potential space saving and Link2SD's stability combined together and gives you something to brag about.
PREPARATIONS
Download the latest build of CyanogenMod 9.
Download the latest version of CronMod INT2EXT+ here.
Open CyanogenMod 9 zip.
Navigate to /system/etc/init.d
Open INT2EXT+ zip.
Navigate to /system/etc/init.d
Add the file called 40int2ext in the /system/etc/init.d directory in CM9 zip.
INSTALLATION
Go to recovery, do factory reset and advanced > partition sd card.
Select 1024M for ext(for some reason, I selected 4096 and it only read the first 1GB-ish) and 0M for swap.
Wait until it says Done and goes to menu.
Go to Mounts and Storage.
Select USB storage and connect your phone to your computer.
Copy your modified CM9 zip file to the root of your sd.
Select unmount.
Reflash ROM.
Reboot.
After reboot, go to settings > developer settings > root access and select Apps and ADB.
Go to your adb directory and do adb shell.
Type su.
Then do:
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd /system/etc/init.d
chmod 644 00banner
chmod 644 90userinit
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
Reboot.
After reboot, reboot into recovery and flash gapps.zip normally.
Then go to Applications and enjoy your new, extended internal storage.

can someone help me how to do adb shell and go to adb directory
Use the directory that you used to root your device.

Err, now that's funny. To do adb shell, all you have to do is put in the command adb shell
Isn't that funny? xD
What the guide meant for adb directory is the place where the adb.exe file is kept.
So all you have to do is put in cmd:
adb shell
and while you're in shell you just put in those commands:
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd /system/etc/init.d
chmod 644 00banner
chmod 644 90userinit
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
After that to close the terminal, type in:
exit
then adb reboot
Hope that helps =)

Hmmm, you don't need adb for this. Just use terminal emulator on your phone. It comes installed by default on CM9 roms. Or you can search play store for android terminal emulator. The app is by Jack Palevich
Code:
su
mount -rwo remount /system
cd /system/etc/init.d
chmod 644 00banner
chmod 644 90userinit
mount -ro remount /system
Then again, I don't really see why it is necessary to deny execute permissions to these scripts in first place. They are just empty shells - unless they have been modified.
I'm using int2ext4 right now and never really had to...
EDIT: If you want to reverse these changes then
Code:
su
mount -rwo remount /system
chmod -R 755 /system/etc/init.d
mount -ro remount /system

As of link2sd it uses installrecovery.sh file in /system/etc to mount sd-ext partition. It then moves apps/data/dalvik-cache to sd-ext and places symlinks at the original locations.
Take a look here where i've explained why symlink based apps/scripts should not be used on HTC explorer.
Hit thanks if i helped!:good::good:
