Welcome to our AndroidForums, Chamuth.
When I edited a file with
Root Explorer and saved my changes, it told me and indeed created a copy of the original file in the same folder with a "
.bak" extension.
So, hopefully you've got USB debugging enabled and have the ability to use the
adb utility (we already know you are rooted):
- connect your phone to your PC with your USB cable
- launch
adb from your PC:
c:\> adb shell
$ su
# mount -o remount,rw /system
# cd /system
# ls build.prop*
if you do NOT see a build.prop.bak file here, then do NOT proceed any further!
# mv build.prop build.prop.BAD
# mv build.prop.bak build.prop
# mount -o remount,ro /system
# exit
$ exit
If you do NOT have USB debugging enabled, but have a custom recovery (CWM, TWRP, etc.) installed (which will have USB debugging enabled and allow adb usage), you'll have to first launch the custom recovery, then used the Advanced menu (or Mounts) and mount your /system partition; then use these commands (similar to the above) to rename your build.prop files:
c:\> adb shell
$ su
# cd /system
# ls build.prop*
if you do NOT see a build.prop.bak file here, then do NOT proceed any further!
# mv build.prop build.prop.BAD
# mv build.prop.bak build.prop
# exit
$ exit
If you have questions about the above or are unclear, please ask first before proceeding.
Note: I do not have the Micromax A27 device, but these fairly generic instructions should work for you.
Also,
always take a Nandroid backup before making a change to anything system related--or, have the knowledge in-hand to get out of situations likes this before attempting.
