I rooted my micromax a27 a few days back. It installed an app Kinguser to give root permission.

Earlier it was working fine.

I did a factory reset last night.

Now, when I try to copy file to root folders like /system/media/ directory. It gives error as Permission Denied.

Please help how to recover root access.

I am using ES explorer with root access enabled.

  • Have you re-mounted /system before trying to copy? That partition usually is mounted read-only – so of course write permission is denied. – Izzy Dec 2 '14 at 12:12
  • how to re-mount /system ? – Anuj TBE Dec 3 '14 at 10:25
  • Multiple ways: adb remount, or (via adb shell or a terminal app after becoming root) mount -o remount,rw /system, or using root-filemanagers which have this capability built-in. – Izzy Dec 3 '14 at 11:14
  • I think i have lost root on my phone. as after checking root status using root checker is says Not Rooted – Anuj TBE Dec 5 '14 at 10:26
  • I wonder why ES is not explaining about that then. But if root checker fails, there must be some issue with root. "How to root the A27" would be a separate question (it's not yet listed in our rooting index). – Izzy Dec 5 '14 at 10:45

In es file manager, slide the menu out and tap on "root explorer" (not the switch) and choose mount rw. Then tap on the radio button in the rw column for all rows. Now you should be able to write to those partitions.
