Hi i moved some files from system/app into the sd card to get some space so i could use the metamorph app but i didnt work so i was going to move back the files from the sd card to system/app but now they wont move there anyone know a soloution how to do this?
thanks in advance
system is readonly
you must do an
adb shell
mount /dev/block/mtdblock3 /system
then you can fool around with your system apps
mount /dev/block/mtdblock3 /system || I wrote that but it says
"mount: mounting /dev/block/mtdblock3 on /system failed: Device or resource busy"
i rooted my phone yesterday quite knew to android and i have no clue what to do
You are doing that in recovery mode right?
I tried in ClockworkMod Recovery v2.5.0.1 but it says Device or resource busy :/ have no clue.
ClockworkMod has a nice green menu on screen from where you can see (partitions menu) which partitions are already mounter and which are not.
You can also do adb shell and run "mount" in it to see which partitions are mounted and in what way. ClockworkMod has /etc/fstab so you can mount system just by running "mount /system". If system is already mounted, you can cd to /system/app and try "touch test". If you get permission denied then your system is mounted read-only otherwise you will see test file in /system/app if you run "ls".
I did adb shell and did run "mount" and it says /dev/block/mtdblock3/ on /system type yaffs2 <ro>
I downloaded a app called root explore and the main reason for that was so i could move some files from system/app so i could get some free space so i could use metamorph that was my plan and i moved some files i have eard you could move that wouldnt harm anything but it wasnt enough free space, so my plan was to move back the files i had moved into the sd card some went great but i have like 4 files that i cant bks it says "You cannot paste here because the file system is read-only" is there any other way to push those file into the system/app again? have tried the things u wrote up.
And im not a very pro of theese things i started with this yesterday so excuse me for being stupid!
This:
/dev/block/mtdblock3/ on /system type yaffs2 <ro>
...means that system is mounted read-only (mind that "ro" at the end).
Try running "mount -o remount,rw /system". If it doesn't help run "cat /etc/fstab" and post here the output. You need to be in recovery mode while doing this of course!
did "mount -o remount,rw /system" and it said mount: can't find /system in /proc/mounts
and the other one said
/dev/block/mtdblock4 /cache yaffs2 rw
/dev/block/mtdblock5 /data yaffs2rw
/dev/block/mtdblock3 /system yaffs2 rw
/dev/block/mmcblk0p1 /sdcard vfat rw
/dev/block/mmcblk0p2 /sd-ext auto rw
used my brain a little now and in the recovery settings i did mount the /system in the menu and now i tried to write cd /system/app and now in the cmd it is like this "/system/app #" anything useful?
Sure... as I already told you try to run "touch /system/app/test". This command shoud make empty test file in /system/app. If you get permission denied then you have read-only system. If it suceede, then your /system is writable and you can see all the contents of /system/app by runing "ls".
I wrote that and it wrote the same
"touch /system/app/test"
no permmission denied then it may have worked?
i checked and there is a testfile in /system/app now
I think i got it to work now thanks man for all your help!
First, you need to install the drivers:
http://www.samsung.com/us/support/d...R&prd_mdl_name=SPH-D700&prd_ia_sub_class_cd=P
Then you must be rooted:
http://forum.xda-developers.com/showthread.php?t=775110
Next, get the most current SDK:
http://developer.android.com/sdk/index.html
Extract the zip and put it where it's easiest for you to get to on Command Prompt. I put it in my C:\ for extremely easy access.
Now, open up Command Prompt and put in these commands in order
1.
Code:
cd C:\android-sdk-windows\tools
2.
Code:
adb devices
3.
Code:
adb shell
4.
Code:
su
5.
Code:
mount -t rfs -o remount,rw /dev/block/stl9 /system
6.
Code:
cd /system/app
7.
Code:
ls
Now you should see a list of all the pre-installed Apps on your device. To remove these apps you must use this command:
Code:
rm "app_name.apk" or rm "odex_name.odex"
Here is a list of all the pre-installed apps on the stock Epic ROM and an explaination for most of them:
http://forum.xda-developers.com/showthread.php?t=773142
-------------------------
Here is my suggested list to use:
Code:
rm amazonmp3.apk[LEFT]rm Asphalt5_DEMO_ANMP_Samsung_D700_Sprint_ML.apk[/LEFT]
rm MediaHub.apk
rm nascar09-prod-release.apk

rm SN28-1092-sprint-signed.apk

[LEFT]rm SprintTV.apk

rm SprintZone.apk
[LEFT]rm MobileAP.apk - Only if you don't pay for the $30 hotspot[/LEFT]
rm MobileAP.odex - Only if you don't pay for the $30 hotspot

Titanium backup is easier and less time consuming then messing with ADB and is free.
Eh, not really. ADB is much more resourceful and has alot more uses and options if you learn how to use it. This is only one of it's uses. Titanium Backup is just a waste of space IMO. It is very limited on the free version.
Or you can use SDX App Removal if your interested in only removing the preinstalled apps (must be rooted).

At the expense of sounding like a noob, which I guess I am when it comes to Android, I'm getting a real-only error. I rooted with noobnl and Titanium Backup tells me I'm rooted. What might I be doing wrong?
Try using this as the mount command:
mount -t rfs -o remount,rw /dev/block/stl9 /system
Or better yet use one of the GUI options unless you are familiar with linux and save the headache. If all you want to do is remove apps there are far easier methods that are less time consuming. Titanium backup and SDX removal tool are both free.

Mine is Wildfire, I have some issues:
Can not do this:
mount /dev/block/mtdblock4 /system
or
mount -t rfs -o remount,rw /dev/block/stl9 /system
But actual there exists a directory /system/app, in which I can see all the .apk and .odex files. When I tried to delete a file, it says that 'rm failed for File-Name, read-only file system'
What should I do? thanks

Now I can mount, to over come the read-only problem, however whenever I delete a file, it says that: rm failed for filename.apk, Directory not empty
You guys have any advice? thanks

I tried to reboot in HBOOT/Recovery/ Partition Menu, then mount /system. Then I could remove apps in adb shell successfully. can anyone confirm that doing like this is ok?

If it works then it should be fine

My noob question is I am using titanium backup to remove the sprint bloatware like media hub and it looks like the program removes it but when I exit titanium it is still on the phone.

Titanium backup is the mark of the noob in my opinion.
thanks, i had been searching around for the adb commands to mount the system r/w so i could remove the bloat.
SDX Stock App Removal is tops in my opinion.
Quick, simple, and allows for back-ups.
And I also don't think Titanium is the "Mark of the noob". It would be more like the "Mark of the ADB is unnecessary for stock application removal"
Also I don't think this should be in development. And if you know ABD commands you should know that.
This thread is okay....but sdx..and root uninstaller are awsome. Thanks for this guide though my friend very useful info for those that want to experiment with adb....

More options is a good thing. This is also helpful for the noobs who want to get their feet wet with unix/linux shell commands.
Hi!
I have rooted my phone (LG Optimus 2X) and mistakenly deleted some files.
I have these files, and want to push them back using adb, put my problem is, that when i try to mount the system in read / write mode using "adb remount" i get this error: "remount faileded: Operation not permitted".
I can't figure out how to fix it, i can pull files etc.
I have also tried to use the adb shell, and copy the files from the internal sdcard, but i'm getting the same error.
Only read-mode.. :/
Anybody who can help, fixing this problem?
If you want to mount /system just write:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Then you're good to go

Mount r/w
Code:

Mount r/only
Code:

Hi, I follow the goide, but my root dont work on 100%. For example titanium backup works, root checker say that I have root. BUT when I want rename somu app I cant - (I want my camera sound off http://forum.xda-developers.com/showthread.php?t=1882926 )

Where is problem?
Can't help you with your problem exactly, but why dont you choose Camera Sound 4?
Sound 4 = Sound off
Sound 4 = sound off, after you change the file CameraApp.apk... BUT I cant du this - look on the screens.
AW: My root dont work?
You must remount the /system partition as rw (readable AND writable). Use a file manager which can do that (e.g. ES File Explorer). Usually there's an option in their settings menu to mount /system writable. Or use terminal emulator and type
Code:
su
mount -o remount, rw /system
Remember to mount the partition as read-only again afterwards.

Worked for me! THX
I have a rooted Pixel 7 and It was suggested that I rename a system file to prevent the system from updating itself (despite my having turned off all such options). My first attempt was to merely try renaming the file, but that didn’t work because the file systems in mounted RO.
I did some looking around, and the common approach to dealing with this issue is to remount the file system. Following is a ‘screen grab’ of my abd session:
Code:
cheetah:/ $ su
cheetah:/ $ ls /product
app etc fonts framework lib lib64 lost+found media overlay priv-app tts usr wallpaper
(this has the directory I want, so this file system)
cheetah:/ $ mount | grep product
/dev/block/dm-15 on /product type ext4 (ro,seclabel,relatime)
(this is a mounted file system)
cheetah:/ # mount -o rw,remount /product
'/dev/block/dm-15' is read-only
cheetah:/ # mount -o rw,remount -t ext4 /product
'/dev/block/dm-15' is read-only
cheetah:/ # mount -o rw,remount /dev/block/dm-15 /product
'/dev/block/dm-15' is read-only
(three attempts to remount – all failed)
So, now what should I try?

Thank you. Seems like this might work, but after reading several pages, I am not sure how to install/use overlayfs. I have a Windows system - any chance you could point me to something that provides some guidance?

I've never used this before but I believe once you flash the module it makes the /system RW so you can start making modifications. There's a README that provides some information. I don't know of any other guides besides the information on that Github page.

Good suggestion. I installed FX File Explorer, gave it the appropriate permissions, but was unable to change the /product filesystem to read/write.

When you say "gave it the appropriate permissions", just to confirm -- that doesn't mean that you changed the security permissions on the folder & files, correct? I hope it means you did not do what the OP in that thread had done and actually did enable root access particularly (hoping that's what you meant on "gave it appropriate permissions").
Because, in certain cases, I've changed permissions on files/folders vs. simply enabling root access mode....
Apologies in advanced if my inquiry seems fairly obvious (to the point of insulting maybe; it is not meant to be), but you never know and many foolish things has been done/assumed on this site that missed many (obvious) things because it wasn't confirmed....
