How can I run 'adb root' on Nexus One - Nexus One Q&A, Help & Troubleshooting

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...

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.

[FIXED] Remount failed: operation not permitted

Ok, I'm not a total noob. I've been trying to return to 1.5 as cleanly as possible, but now I'm having an error when trying to remount my phone.
Code:
C:\android-sdk-windows\tools>adb devices
List of devices attached
HT9C1HF03306 device
C:\android-sdk-windows\tools>adb remount
remount failed: Operation not permitted
C:\android-sdk-windows\tools>adb shell
$ su
su
#
This is what I did:
Flashed the 1.5 RUU that Flipz has had out for months. No errors
Ran the Avalaunch PRI fix to get rid of the flipz_01 PRI name
updated my profile
updated my PRL (which is now 65000??)
rooted through the normal sequence without error, I can boot to the recovery just fine, but when I adb shell into the phone I end up at $ instead of #. I have to su to get to # and at the c:\windows-sdk-windows\tools\adb remount fails with "remount failed: operation not permitted"
Is it possible that the PRI update has foiled the root exploit? I even restored a nand backup that I know had a working root and I still have the same results. This is too weird.
Anyone else have this issue? I searched the forum but I came up empty.
Try adb remount before adb shell. I'm pretty sure anythig with adb should be ran at just the command prompt.
Someone feel free to correct me if I'm wrong.
right, this is at the c:\android-sdk-windows\tools\ prompt. I guess I need to re-word that last bullet point to be more clear.
Code:
C:\android-sdk-windows\tools>adb devices
List of devices attached
HT9C1HF03306 device
C:\android-sdk-windows\tools>adb remount
remount failed: Operation not permitted
C:\android-sdk-windows\tools>adb shell
$ su
su

Yeah the wording got me. I was hoping it was as simple as that for you tho. Defiantly Strange. Believe me I've had plenty of those moments where hours would have been saved if someone could have just said "no your just doing it wrong".
Maybe try rerunning the RUU and start from scratch the PRI fix should hold thru the RUU but if it did affect something else running the RUU again may correct it.
I RUU'd about 4 times so far on two different laptops, one with XP and one with Win7, running both versions of the HTC Sync drivers.
Something is definitely different. I'm thinking of doing the PRI fix again to see if that helps. The PRL being 65000 instead of the normal 60664 is another anomaly I'm curious about.
looks as if the 65000 PRL is a new one. I can't confirm (not with Sprint) but there is a thread over in General talking about it.

YEAH! I fixed it....well....actually Flipz fixed it for me. I created a custom ROM in the kitchen and flashed it. Now the remount miraculously works. I'm back to being happy...though I don't know why. Its not like I was using root for anything

I found something that help me and you. it properly works!!
I can't spell out instructions for the above mentioned suggestion, since I
don't know which file editor comes on the shipped device, but I have an
alternative solution.From the SDK's tools directory, run adb shell. In the
prompt run the following:
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system (Or any subdirectory you want to push to inside system)
# exit
adb push <local file> <device location>
and eventually you should restore the original directory permissions by:
# chmod 755 /system (Or any subdirectory you modified permissions to)
Hope this helps,
Yoav

still no Read/Write on /system
I tried the above, and I could not mount /system as read/write:
Code:
adb shell
$ su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Permission denied
$ mount: Operation not permitted
My Android 1.6 is rooted, so I feel like I should be able to do this. But any help would be...helpful.

Just cd to your tools directory and adb remount

Is there a solution for this?
I have a rooted HTC Desire.
When I type adb remount I get permission denied.
When I type adb shell and then su , i get permission denied!
This was a stock 2.2 rooted with unrevoked 3.
Any idea?
[edit]
i noticed root permissions pop-up on the phone and allowed so su worked.

EDIT: I have set S-OFF using AlphaRev's recovery fastboot and I am now able to remount in rw (well no access denied anymore)
still missing some access as I fail to remove the Google Maps app (want to use Brut maps only)

Don't mean to bring up this dead thread but a more simple solution would be this
adb shell
$ su
# busybox mount -o remount,rw /system (or another desired directory)
# chmod 777 (or another desired permission set) /system (or another desired directory)
# exit
$ exit

[Q] Problem with ADB and Removing Apps

I'm not new to coding per se, I'm a web designer and developer and most of this makes complete sense to me, but I'm not sure what I'm doing wrong here. I have decided I want to learn more by customizing the stock .5 RUU rom (reverted back from .6). So I am working on removing the stock Sprint apps at the moment. I rooted via UnrEVOked one-touch. I am running ROM Manager with the ClockWorkMod Recovery Image.
Here's my setup. I'm running Parallels on my Macbook with Windows XP. I added android-sdk-windows to my C:\ drive and started into the ADB. (I do have SU permission). I have USB Debugging running and I'm in Charge Only Mode.
Code:
C:\android-sdk-windows\tools>adb shell
$ su
su
[B]mount -o rw,remount Permission denied[/B]
$ # mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
$ cd system/app
cd system/app
$ ls
[Returns the long list of System Apps that are installed ]
$ # rm amazonmp3.apk
# rm amazonmp3.apk
$ exit
C:\android-sdk-windows\tools> exit
This is just an test, trying to remove the amazonmp3.apk. I reboot into recovery and reboot the system from there, but the app isn't removed. I've highlighted the possible "problem" commands. - The "Permission denied" error is automatic, I don't get to finish writing the remount code before it automatically gives me the "denied" error
Any ideas on what I'm doing wrong? I've read that the UnrEVOked app doesn't give you full root access, is this correct?
When in tools directory type
Adb remount
Adb shell
Rm (app name).apk /system/app
or if you removing several apps you may want to cd into the app dir
Code:
adb remount
adb shell
cd /system/app
rm amazonmp3.apk
yeah, I think that the UnrEVOked one-touch just doesn't cut it because I get Permission denied on the "adb remount" command
getting this:
Code:
adb shell
$ cd /system/app
cd /system/app
rm amazonmp3.apk
rm failed for amazonmp3.apk, Read-only file system

Not really sure cause I've never used that method of rooting. Try using the regaw version found in the android Dev forum

[tutorial]Root any latest firmware with ease

Firstly what i would like to say is this is not a one click root like update.zip or superoneclick you will need to have some basic knowledge of adb and ubuntu and a little bit working mind which can follow the provided steps.
Requirements:-
*cwm recovery already flashed (if not refer here)
* Working linux distro (ubuntu, mint, kubuntu etc.) with atleast sudo rights
* adb setted-up (if not refer here, may not need to follow the usb drivers steps)
* must know how to use adb
* superuser package from here
Click to expand...
Click to collapse
So we are now ready to start
STEPS:-
1. Extract all file (su, busybox) from the downloaded package to the folder where you have adb setted-up
2. open a terminal
3. cd to the directory where you have placed adb and files
4. boot your phone into cwm recovery mode (home power) connect through usb
5. type "sudo chown root:shell /path to su"
6. type "sudo chmod 06755 /path to su"
7. type " sudo chmod 04755 /path to busybox"
8. type " adb devices" if you will see anything attached you are good to go
9. type " adb remount" if you get remount succedd then you can do below steps if not you are doing something wrong do again
10. type "adb push su /system/xbin"
11. type "adb push busybox /system/xbin
12. type adb push supersu.apk ( or what it is called) /system/app
13. now type "adb shell"
14. type su if accepted then you are rooted
15. now type "reboot"
Click to expand...
Click to collapse
you are successfully rooted
enjoy your phone
awesome guide buddy very useful for n0obs
First of all great guide! But please correct these:
You have to mount the system partition manually. Adb remount won't do it!
adb shell
# mount -rw -t rfs /dev/block/stl12 /system
Do chmod/chown in adb. It isn't enough to set it before copying.
# chown root:shell /system/xbin/*
# chmod 06755 /system/xbin/su
# chmod 04755 /system/xbin/busybox
# chmod 04755 /system/xbin/sqlite3
# chmod 04755 /system/xbin/ssh
if we were able to chmod with adb there was no need to use ubuntu
we cannot chmod it shows operation not permitted as as we yet dont have root
have you tried to do adb remount or just saying that i will not do the work
and thanks for chown part

Hi!
For me, adb remount didn't work. It exited with an error code. I don't remember the exact error code... (cwm couldn't mount too)
When I experienced "operation not permitted" while chmoding, the partition was mounted as vfat! Because if you do "mount /dev/... /system" without switches, it automatically mounts it as vfat. In vfat you can't set setuid, setgid permissions.
I think it was just a coincidence that i could rooted with ubuntu. But it worked, so better to use linux (better adb perhaps?).
Rooting is a bit strange in this new firmware. For example when you do "adb shell" while the phone is in cwm, you have root access. So you have to do those things manually while you have temporary root access.
how can you mount rfs file system as vfat i dont think it can be done

Yes it's really strange. I don't know how this thing possible too...
But I checked multiple times with "cat /proc/mounts" , and mounting without "-t rfs" it was mounted as vfat.
a bit of googling:
"You can mount as rfs as Fat in ubuntu and read/copy the files
editing them wont work at all ."
So maybe it is possible.

[Q] /system/vendor is read-only

Everything was tried, adb terminal, adb pc, different file explorers but that folder stays read-only, even can't change permissions, MAgisk 17.1. ANy ideas?

be careful what you wish for...
you need to remount the partitions. you can do this through adb shell or terminal emulator on your device.
Adb commands
Code:
adb shell
su
mount -o rw,remount -t ext4 /system
mount -o rw,remount -t ext4 /vendor

In response for remount /vendor, it gives

You need to unlock the other parts of your bootloader then. It will factory reset the device, but you need unlock flashing and unlock flashing critical. This let's you remount critical partitions. Vendor is a critical partition.
