i'm new to adb. i finally got it working. the correct string is added to Path, it's in my root directory C:\. i'm able to list my device, list directories, and even push/pull (did test to sdcard). i cannot, however, mount the /system directory to r/w.
this is what's happening
C:\android\android-sdk_r06-windows\android-sdk-windows\tools> adb remount
remount failed: Invalid argument
i'm in recovery trying to do this. anyone know what's going on or can maybe lend some help? thank you

if you do not have a rooted, NAND unlocked, phone, you will not be able to mount /system

it is rooted and NAND unlocked lol
i was actually able to push but not where i wanted.
i did
adb push com.htc.resources.apk /system/framework
but that's not where it needs to go
so i then did
adb push com.htc.resources.apk /system/framework/
and it says /system/framework is a directory, which i know lol that's where i need the file to go.
oh yeah, and i got it mounted as r/w. so now i'm just having trouble getting the file where it needs to be with the whole "is a directory" error instead of it actually pushing the file. still unable to pull a file from that location, though.
try writing the filename. it 'should' append it automatically, but if not then try
adb push com.htc.resources.apk /system/framework/com.htc.resources.apk

/system is under mtdblock4 on our device.
if you need to mount /system as read/writeable from adb, you should just be able to use
adb remount
if you are doing it in shell, use mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system

thanks. yeah i started just killing it in task manager
after using "mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system" and trying to pull, i'm still getting /system/framework/com.htc.resources.apk does not exist
yeah, not sure what to tell you then. i can't piddle around in my own, because i'm on cm6, and won't have that.
are you sure it exists?
adb shell
# cd /system/framework
# ls
that will tell you what's in there. if you can't see it, it's not there.
from a brand new shell, (or bounce back up to the root directory)
try
find -name "*resources*.*"
that should tell you every file that contains 'resources' as a part of the file name, and where it is located.

that was prob the case, can't remember if i re-mounted or not when i was doing that. regardless, i was positively mounted when trying to push/pull and it wasn't working so i guess i'll just have to wait for someone to put it in a flashable zip.
i hate adb
thanks for your help dude
Hello there,
does anyone know how to mount the galaxy s4 as writeable via adb?
mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p9 /system
is the Red Coloured the right Path?

omg no no no no.
if you are talking about trying to use "adb push <name of file> <destination file>"
Then you must use "adb remount" if it fails, you are not on an insecure kernel. Thus your only option is to push to the sdcard then use "adb shell" and navigate to your sd card and use "cp <name of file on sdcard> <destination file location>"
as for the commands, it is NOT what you have posted. it is simply
mount -o rw,remount /system
nothing else is needed. You will seriously mess something up if you try mounting it as yaffs2 considering we use ext4 now. FYI, the above command can only be entered AFTER first entering "adb shell" which gives you a command line on the device to execute commands.

Then you need to use
adb shell mount -o rw,remount /system
thats it. To uninstall apks, use:
adb uninstall <package name>
And you are getting a read only system error because you are trying to create that "file.txt" file onto your "root" directory.
do this:
adb shell cd /data/media/0
then try to do your list packages.
I'm currently trying to use adb to push a ROM to my sdcard on my Verizon Galaxy Nexus. However, it keeps failing due to /sdcard being a read-only filesystem.
When I adb shell into the phone and type mount, i get this (among others):
Code:
/dev/block/mmcblk0p12 on /sdcard type ext4 <ro,relatime,barrier=1,data=ordered>
Attempting to mount /sdcard as read-write is not proving fruitful:
Code:
mount -o remount rw /sdcard
Can anyone help? I'm just trying to get a rom on there so i can install it. Unfortunately, the phone never leaves the google screen when i try to boot, so recovery and fastboot are my only options.
mount -o rw,remount /dev/block/mmcblk0p12 /sdcard
try that

To make things easier, copy the .zip file to the folder where you have ADB then try
adb push ./rom.zip /sdcard/rom.zip
I never could get things to push to sdcard while in recovery mode no matter what I tried.

Hello there, my samsung galaxy s2 i9100's internal sdcard suddenly became read-only shortly after updating it to 4.1. I've tried using the command: ''mount -o remount, rw /sdcard'' which works until i reboot or connect it to an external usb storage device. I'm kindly asking if anyone knows a permanent solution to my problem. P.S- I'm a bit new to this android thing so make your explanations as easy as possible. Please help
Just wanted to know if anyone knows how to disable the virtual cdrom in OOS when you plug in usb to pc. I have looked and there is no cdrom.iso like other phones i had.
Edit: Just overlooked the file.
If anyone is interested in disabling the virtual cdrom upon usb connection, navigate to /system/etc with a root filemanager and rename usb_drivers.iso to usb_drivers.iso.bak and reboot. or enter the following commands in adb shell and reboot. Phone MUST be rooted.
Code:
adb shell
su
mount -o remount,rw /system
mv /system/etc/usb_drivers.iso /system/etc/usb_drivers.iso.bak
mount -o remount,ro /system
Revert
Code:
adb shell
su
mount -o remount,rw /system
mv /system/etc/usb_drivers.iso.bak /system/etc/usb_drivers.iso
mount -o remount,ro /system
Edit: fixed a typo
for everyone getting this Error:
mount: '/dev/block/bootdevice/by-name/system_b'->'/system': Device or resource busy

Has anyone been able to remount /system as rw? FX File Explorer says it's successful but then switches automatically back to read only
I'm also trying to remount /system as rw. It seems that the patched Magisk boot file provided in this post preserves dm-verity, which disallows system partition modifications and makes it unable to remount as rw. The mount command will complain that '/dev/block/dm-8' is read-only.
Having tried repatch the boot image with unchecked 'preserve AVB 2.0/dm-verity' in the Magisk app, but resulted in a crash during boot (QUALCOMM CrashDump Mode). Can succesfully boot with that option checked. It would be fine if dm-verity can be disabled in other ways.

Have you tried fastboot?
fastboot oem disable_dm_verity
If it causes problems, replace disable with enable to get back to current state, but it shouldn't
I don't like to disable dm verity for performance concerns, but for now it would be okay until a new root method comes out

Correct me if I'm wrong,but devices released with Android 10 out if the box will not allow making changes to the system( i.e it will remain read-only only)

You cant mount system as r/w because android 10 is read only
