Hey guys,
When i try to mount system :
Code:
[email protected]:/# mount -o rw, remount /dev/block/system
mount: read-only file system
There is the problem.
Please help i'm stuck with that since 4 hours
I have no idea, but maybe you can find something useful here? If not, try googling "can't mount android system read-only" or the output from your terminal.
Thank you
I've already seen the thread and nothing worked for me i will search a little bit more on google and if I find something will post it here.

hi,
guys i am having trouble with my phone all of a sudden.
I flashed back to stock ED05 and now my /system rfs partition is READ ONLY.
I found out its only read only, because i couldn't root anymore. I need root for titanium backup so i can restore my apps.
How do i change it to Readwrite?
Im trying to remount, but i am having problems
i went into cmd > adb shell > window opened up i typed mount -o rw,remount -t rfs /dev/block/stl9 (the stl9 is my /system i think from the look of the screenshot if i am wrong plz post)
and then i tried chmod 777 /system
it says UNABLE TO chmod /system read-only file system

-odin doesnt fix it
-trying to get root but since /system is read-only i cant get root

I'm having the same problem. Tried using the Samsung root package mentioned in another thread and it fails to mount the system directory.
I just got my Fascinate this weekend due to a warranty swap from another phone. It ran the update to ED05 when I OTA'd it. Is this something locked down in ED05?
FYI, just found this thread and had no problems doing it the manual way. try it out.

Of the 20+ Android phones I have had, and each being rooted and ROM'd, this is the first that I have seen.
On the TPC ROM, when my phone boots, my /system & /etc are mounted by default as Read/Write rather than Read Only. I have no such problem when I flash SAUROM.
I can set it to R/O, reboot, it becomes R/W again.
I asked the question in the ROM thread but got no help. It seems that others don't have this problem.
Why is this and how do I fix it?
Thanks.
Edit: The mount point is /dev/block/mmcblk0p24 for /system and /etc. There are some remount commands in a file located in init.d. Could that be the cause?
I'm no dev, but have you looked at the superuser logs to see what app might be changing r/rw modes? You say when you reboot it changes back. So that makes me think an app you have auto starting is mounting the system rw to make a change and failing to mount back to R.
Go in SuperUser.. clear the logs, set it to R, make note that it saved that change in the log using whatever program you use it to set with... Reboot, check Superuser logs to see what gained root and changed it back.

Thanks for the suggestion. I removed all the apps that requested SU on boot, but the ROM still had /system as R/W. I don't think it's an app doing it.
Is there a way for me to add something into a boot script to set it as R/O?
Thanks.
I'm still trying to track down this problem.
I noticed that /etc also mounts as R/W by default. I see that both /system and /etc share the same mount point: /dev/block/mmcblk0p24.
I look in init.d and found one file which contained these lines:
#mount fs for faster IO speeds
mount -o remount,nodev,noatime,nodiratime /dev/block/mmcblk0p24 /system
mount -o remount,noauto_da_alloc,nodev,noatime,nodiratime /dev/block/mmcblk0p25 /data
mount -o remount,noauto_da_alloc /dev/block/mmcblk0p26 /cache
Would the first line cause this?
Is there something I can add to init.d to re-mount as R/O?
I'm still curious as to what is causing this. Thanks for any help.
Through trial and error, I found this command works to set /system and /etc to RO:
mount -o remount,ro /dev/block/mmcblk0p24 /system
I added it to init.d, and it works. Once the phone completes the boot, those directories are RO. It's just a patch.
But nevermind that--I am still very interested in the "why" and if there is some other script/boot command somewhere that is causing this.
I'd appreciate some guidance. Thanks.
So I'm trying to make Google play music save on my sdcard and I'm having a problem with the script. First the phone I have is the DROID RAZR MAXX and I just did a FDR because of a root problem and now that I have it rooted the scripts aren't working. My script text is this
"Mount -o bind sdcard-ext/MusicCache sdcard/Android/data/com.google.Android.music" I'm really not sure whats wrong so hopefully someone here can help me out.
The error it shows is like this:
exec sh '/mnt/sdcard/MusicScript.txt'
card/MusicScript.txt'
/mnt/sdcard/MusicScript.txt[2]: Mount: not found
Also sorry if I posted this in the wrong spot I'm new here and there's a lot of places to visit.

Hi guys
I need some serious help with my phone... i accidently edited build.prop and now my phone doesn't boot anymore.
I need to push a new build.prop file to my phone.. I can get into recovery mode on the phone and I've managed to pull build.prop from the phone but I cannot push it back due to "Permission Denied"
Does anyone know a adb command or application or something that can help me sort this out?
My phone is the Huawei Ascend P2
Thanks guys.

Android: ADB – Mount a filesystem read-write
Mount a filesystem read-write
Very often when you want to write files to a particular partition on ADP1, you will get a “Permission Denied” if the partition is mounted read-only.
To get around this, you need to mount the partition read-write. Typically this is done with /system partition
$adb shell
$ su
$mount -o rw,remount -t yaffs2 /dev/block /mtdblock3 /system
(Replace /dev/block/mtdblock3 & /system with appropriate device path and mount point, as obtained from cat /proc/mounts)
This was the first result on Bing with the search terms "adb mount read write"

HI Dragon
Thanks for your post
I am getting the error "sh: -o: not found" with the last command
I'm not entirely sure on how to use the remount command.. I'm trying to mount the system partition i guess?
could you please provide some noobish info on how to get this done?
I don't know what "/dev/block" means, nor "mtdblock3" .. I know /system is the part with build.prop in though
Edit: device not found
adb devices
You see yours? Good
adb shell
mount
This may tell you or try
adb shell
cat /proc/partitions
Or maybe
ls -l -a /dev/block/platform
Then from here find chip and search this and so on and so and if you find a by-name directory your good

I was trying to copy a update file to the sdcard, but I kept getting permission denied, so I went into adb shell and tried remounting the phone with rw permissions and it kept saying "Device not found" ..
I think im just gonna have to take it back to 3 and wait 50 weeks to get it back
Hi all.
I apologize ahead of time that this thread is so long, but I have quite a problem. I am in the process of rooting my unlocked Galaxy S4 running Android 5.0.1 lolipop, but I cannot add the su and busybox to my /system/bin folder because /system is a read-only filesystem. I have done just about everything I can think of to mount and remount, like typing adb remount and mount -o remount,rw /system, but they just give me the same answer saying permission is denied. I tried doing adb root to get the permission I needed, but I got an error message saying that adbd cannot run as root in production builds. After doing some research, I found out that the /default.prop has debuggable=0 and that may be what is not allowing me to restart adb as root. So I opened the shell and typed cat to see and sure enough it was set to 0. So I did echo and set the variable to 1. However, whenever I hit enter, I got another error telling me the same thing, that /default.prop is a read-only file. I am at a loss of what to do now. How I can mount and unmount the /system if I can't get any permission to do so? Any help would be greatly appreciated. I do ask though, please don't recommend ready made apps that can insta-root your phone like a supah-hackah because I want to do this the hard way for gratification's sake. I am just stuck and need some help to get the /system to allow writing as opposed to read-only. Thanks in advance.
