Hello,
I was in the process of fixing adhoc networking but the last command keeps giving me device or resource busy.
Code:
adb shell mount -o remount,ro /dev/block/mmcblk0p5 /system
What should I do in this instance? If I reboot the nook color, the /system directory would boot up read only, correct?
Thank you,
Filovirus

Tell me what I'm doing wrong here. I'm trying to make a script that will remove some apps whenever I flash a new rom. Here's what I thought would work:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
cd /system/app
rm com.amazon*.apk
rm Mail.apk
rm Development.apk
rm LatinIME.apk
To use it I type:
Code:
$ su
# sh /sdcard/apps.sh
and it just fails at every line. Any help would be appreciated.
On the first line try
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
or your could shortcut it by using
mount /system
Stupid question, but do you have the permissions set to allow root access?
I've done that a few times to realize what my "mistake" was.
well you could just make a script for your PC something along the lines of
Code:
@echo off
adb remount
adb shell rm /system/app/com.amazon*.apk
adb shell rm /system/app/Mail.apk
adb shell rm /system/app/Development.apk
adb shell rm /system/app/LatinIME.apk
adb shell reboot
and rename it to a .bat or .cmd file

Ok so I did that and the script appears to be working. I'll test it when Cyanogen release another update with amazon... Adding the -t yaffs2, what exactly did that do?
The -t is a trigger saying that your going to specify what type of filesystem your mounting, yaffs2 is the type of filesystem
What's the difference between these two (at least why they use the mount command, remount command, or shell command?)
su
mount -o remount,rw /dev/mtdblock3 /system
rm [whatever i want]
mount -o remount,ro /dev/mtdblock3 /system
and
adb remount
adb shell rm [whatever i want]
The first is a terminal command from the phone. (Only requires the phone)
The second is through adb to the phone. (Involves a properly configured adb, computer, usb cable, and phone)

Wow, so people manage to type out all that craziness on the phone huh.
Thanks!
Anytime. Doubt they do that all the time, it would be easier to just make a script if you have to do that more than once. I just use root explorer, it has a button that mounts /system/ -rw.
I'm not sure about other terminals, but you can create aliases in Better Terminal Emulator
alias rw='mount -o remount,rw /dev/mtdblock3 /system'
alias ro='mount -o remount,ro /dev/mtdblock3 /system'
so now all you have to do is type rw or ro and it executes the full command. Or you can create scripts:
su
mount -o remount,rw /dev/mtdblock3 /system
cd /system/bin
echo "#! /system/bin/sh" | tee ro rw
echo "mount -o remount,rw /dev/mtdblock3 /system" >> rw
echo "mount -o remount,ro /dev/mtdblock3 /system" >> ro
chmod 755 rw ro
Same thing, except it executes the scripts instead of an alias.
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...
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
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
Code:
'/dev/block/dm-0' is read-only

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.
