hello, I have an Archos5 unit with the firmware version 1.7.99 android 1.6 on it. i have managed to root the device but I cant figure out how to remount /system read write on the device.
I checked my root ID and its 0.
i have tried mounting with this command : mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
I get an invalid argument if i try mounting from block.
its the same if i try mounting mtdblock5 where cat /proc/mtd5 shows system being located/
i also tried mounting mtd directly but it spits out an error saying block device required.
i would try through android ADB if i could get it working on linux. the windows archos version wont let me remount (vista).
ignoore this thread. i have succeded in doing what i wanted and now have debian apt working in my archos5. since its quite hard to do I will post a how to in another thread.
Hi;
I'm looking for a safe way to root my new A5, firmware 2.0.38, Android 1.6
I want to use Wifi Helper but it requires rooting. I've yet to find how to do this on this machine. Can you help me?

I was never successful using SuperOneClick for the Optimus V. hangs at wating for device.
THOUGH...
I believe I did finally get it rooted using adb and push psneuter, busybox, su and Superuser.apk...via Ubuntu 10.10 Maverick...
I rebooted the device twice...downloaded terminal from the market and sure enough I can su to a # prompt...I take this to confirm I have successfully rooted my Optimus V.
Now to the question....
I found several post most of which included this command in adb shell:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
However I was successful based on a post found here by (Endur):
http://forum.xda-developers.com/showthread.php?p=12076877
with the command
mount -o rw,remount /dev/block/stl9 /system
What is the difference? Have I done something horribly wrong?
And Thank you for all your work here...This is a lot of fun prying into the technologies of today and tomorrow.
Any answer or pointing me in the direction to research on my own would be much appreciated.

Hi, I cannot figure out what I need to write in terminal emulator to gain root access to install cwm. I was hoping someone could post the exact command needed, I would appreciate it alot. I have tried searching but the generic commands i found on a different site didnt work. Thanks!
Can you gain root from terminal emulator? First I have heard this. Why not just Odin one of the modded kernels?

If you're just looking for the command to mount /system as read/write, you'll have to figure out what "device" is used for the mount. From the terminal, type:
mount
That will show you a list of things that are currently mounted. You'll see something like (not exactly):
/dev/block/stl9 /system rfs rw,dirsync,nosuid,nodev,noexec,noatime,nodiratime, uid=1000,gid=1015,fmask=0002,dm
ask=0002,allow_utime=0020,codepage=cp437,iocharset =iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
The part you're interested in is the part before "/system" and that is the block device used to mount your system partition. To mount it read/write, you type (based on this example's block device & based on the rfs vs. ext4 file system):
mount -o rw,remount -t rfs /dev/block/stl9 /system
The -o part tells mount "here come the options" which are read/write & remount. The -t tells it the filesystem type (rfs or ext4, depends on if you have voodoo enabled). The next argument tells it the block device, then what mount point to use.
As for root, what Exodian said. You'll either have to flash a root enabled kernel or use SuperOneClick v2.2.
Hi, this is a blatant crosspost from the android stackexchange site, questions/24081... I posted it there and figured I wouldn't get much help, so I thought I'd try here. Let me know if this is OT or in the wrong place or whatever.
I want to remount a read-only partition in read-write mode, but I want it to be writable for all users.
So far I've got this:
Code:
mount -o bind /someplace /someplace_else
mount -o remount rw /someplace_else
The first command creates a new mount point from a directory. The second one remounts the new mount point as rewritable. This all works.
Problem is, the new mount point has uid=1000,fmask=0222,dmask=0222, so the non-root user still can't write anything, and root can't give it permission.
How do I change the fmask and uid when remounting, or is there something else I can do to make the mount writable for the normal user?
Also, note that the command that worked for me is this:
Code:
mount -o remount rw /someplace_else
...with no comma between "remount" and "rw," as I've seen in almost everything my searches turned up. Does anyone know anything about this discrepancy in syntax?
I'm doing most of this in a terminal emulator on the phone, and in SL4A.
Yes, my phone is a chinese Hero H2000+.
I have managed to stick su and busybox into /system/bin using debugfs, but there's absolutely no way I could find to make /system get into read-write mode.
If I type "mount -o rw,remount /system" it seems to work for about 1 second, but then it's remounted read-only. All the changes will be reverted (files I add/remove via script). If I try to run the same command again, it will show me a message saying filesystem is read only.
Does anyone know what might be causing this?
Thanks in advance.
For some reason I have never been able to mount my system r/w through adb or terminal emulator. I'm not quite sure what I'm doing wrong since I've been doing it for years now. I imagine it has to do with root. I can use ES file explorer and modify system to my hearts content just not through adb or terminal emulator. I am on 7.1.1 Pure Nexus with ElementalX 1.08 and SuperSU with 2.79 binaries. I've tried to mount multiple different ways and all result in same error.
Code:
sailfish:/ # mount -o remount,rw /system
mount: '/dev/block/bootdevice/by-name/system_b'->'/system': Device or resource busy
Nvm found it. I guess it's same as Pixel C.
Code:
mount -o rw,remount /system

Same here but with Oneplus 3T.
I think its kind of encripted "new way" in Android 7.1.1
Also, if you check the magisk thread there is a way to use the mount remount command inside root browser

Nope just a different mount syntax not encrypted at all. I was kinda thinking same at first like a security feature or root keeping you from so you don't accidentally modifying system.
mount -o rw,remount /system
Instead of
mount -o remount,rw /system

Sadly I tried your new syntax, adb did some stuff, but it does not work either.
Anyway thank you very much, your solution almost got it.
