Push build.prop to /system/build.prop

Question

I have edited build.prop and now my phone cannot boot. I have pulled build.prop using adb and now I have the correct build.prop file

What I need is to push build.prop using adb.

First try: Read-only file system

when I mount system:

Second try: Permision Denied

what can I do?

Answer 1

Probably because adb push uses the shell user, which does not have write permissions to /system/build.prop. You can, however, push the file to a different location first (e.g. /data/local/tmp/) and then move the file to the right place with the root user (after mounting).

Answer 2

Here are the commands you need to use:

adb push <Path to build.prop>/build.prop /data/local/tmp/
adb shell
su
mount -o rw,remount /system
adb push /data/local/tmp/build.prop /system/build.prop
