I'm trying the to flash my I9300.
Everything goes well until the ClockworkMod recovery.
So I'm need to get rid of /system/ect/install-recovery.sh and /system/recovery-from-boot.p
but all apps to do so... require root privileges (...).
As I didn't like to give up, I tried...
  • Root Explorer
  • Explorer
  • ES File Explorer
  • Files
  • Total Commander
  • ROM Manager
...but none of those got me rid of those two files...

Does anyone have some advice on how to tackle this?

At the Sprint guide I noticed the TeamEpic-Root-from-Recovery-v5.zip, that deals with this problem, but I strongly doubt I could use that part on a I9300, right?
