Trying to get root access

I can enter the first two commands, mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system,flash_image recovery recovery.img and cd /sdcard but when i type in the last command i get this
cannot open /system/recovery.img no such file

Don't know what you're typing there.. missing some stuff.
Try this:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
cd /system
cat /sdcard/recovery.img > recovery.img
flash_image recovery recovery.img

Did you type SU before??

i did what the first reply did. what do you mean su?

i got it thanks

SU = root access.

Once you have rooted your phone and installed a custom image, you need to type "su" and press enter anytime you go to the command prompt to do something requiring root. Basically root is disabled by default so you don't break things - you need to specifically tell the phone you want root access to try and avoid breaking things by mistake.
Anyway, glad you got it working.

How can I run 'adb root' on Nexus One

Hi,
I have rooted Nexus One which runs on GingerBread. I can open 'adb shell' and then execute 'su' there.
But when I try to 'adb remount', it fails.
Code:
$ adb root
adbd cannot run as root in production builds
$ adb remount
remount failed: Operation not permitted
Basically, I want to copy a file from my Desktop (MacOSX) to /system/bin on the device, is there anyway to do that on my Nexus One?

You rooted a stock OS - it doesn't have insecure boot, so ADB doesn't allow remount and other root commands.

It seems like you are trying a bunch of things without reading beforehand, and understanding what you are doing. As has been said to you before, you cannot use the adb remount command with a secure boot image. If you want read/write access to the /system partition, you need to do the following:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Now you have read/write access to the /system partition. No you can copy files from your sdcard to the system partition if you want. When you are finished with whatever you have to do, don't forget to issue the following command:
mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
There you have it. However, if you would have read a bit, instead of starting a new thread for each question you had, you would already have found what to do...

[Q]: Read-only filesystem

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

A little easier to type...
Mount r/w
Code:
busybox mount -o,remount -rw /system
Mount r/only
Code:
busybox mount -o,remount -r /system
Edit: You shouldn't post stuff like this in dev

try: adb shell mount -o remount,rw system

Code:
adb remount
It should do the trick too

lol, that's shorter indeed

adb remount will only remount an existing mount, it won't create one.
It's not clear what the OP wants.
You don't need rw to deodex a ROM because you certainly don't want to write to system whilst you're doing it.
Also, I thought the stock ROM was deodexed?
To mount system in recovery, which will give you rw access and allow you to pull the files you need you just type:
Code:
mount /system
or
Code:
adb shell mount /system
Because system is included in /proc/mtd

to all: the answer is:
mount -o rw,remount /dev/block/mmcblk0p1 /system

Hi, this seems to work for me:
Open a terminal (Command Prompt).
type adb shell
type su
You should see a # in your prompt.
type mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
and Bingo! Your /system is now mounted as r/w. [NOTE: There will be no confirmation message. Your command will simply be printed again, and that means its a success)
The possible error might be that you forgot the su part. I'm making a wild guess that it stands for superuser. The first time I tried this, I didn't know about the 'su' and I wasted a little time because of that.
Hope this helped.
