Any terminal emulator should do. We use this one.

9. Gain root permissions for terminal emulator

  • In the terminal command window, type “su“. After typing “su“, you should get a popup requesting root permissions for the Terminal Emulator app.
  • You should then see a “#” prompt instead of “$“. This means you’re able to execute root level commands.

  • In the terminal emulator window type “sh /storage/emulated/0/“. Note there is a space after the “sh“.
  • Your phone may then reboot to recovery.

  • Boot into recovery if you’re not already there (from Power Off, hold VolUp+Power until logo shows, then let go of Power and wait until recovery shows).
  • If you’re not already on the official Global, make sure to select “wipe device” along with “update”. This is because you’re changing to a totally different ROM, not just an incremental update. You can try without “wipe device”, but we recommend to do a “clean” install of the new ROM.

Bam! You’re done. Good job.
