3. Unplug the USB cable from the computer and power off your phone.

4. Now, boot into Recovery mode through a button sequence. Press and hold Volume Up, Volume Down and the Power button, until the screen flashes. Then release all the buttons. NOTE: Use volume buttons to browse/navigate and Power button to select options in Recovery.

5. Take a Nandroid backup of your current ROM, so that you can restore it later if something goes wrong with the new ROM. To do a backup, Choose Backup and Restore, then on the next screen, hit Backup again. Return to main recovery menu once backup is done.

6. Now, do a full-data wipe task. To do so, choose wipe data/factory reset and then click Yes on next screen to confirm. Wait for a few minutes until the data wipe process completes.

7. Tap install zip from SDcard, then hit choose zip from sdcard. Now, browse to the rascarlo_maguro-ota-2012-11-26.zip file that you copied to your phone earlier in Step 2 and select it by tapping Power button.

8. Once the ROM is installed, return to the main recovery menu and click Reboot System Now to reboot the phone into the new Android 4.2 Jelly Bean ROM - Rasbeanjelly. The first boot may be time-consuming. So, leave it alone.
