3. Without actually extracting the files, copy the two files downloaded in previous steps directly to the phone.
4. Switch off the power of the phone and boot into TWRP recovery by performing a button sequence. Press and hold the Volume Up + Volume Down + Power buttons together until the display turns on. Browse and locate the Restart Recovery option using the volume buttons for navigation, then select it using the Power button to restart in recovery.
5. Click on Backup, then slide the blue circle button at the bottom to the right to start backing up your current ROM, so that you can restore it later if something goes wrong with the new ROM. Once backup is done, return to the main menu by tapping the home button at the bottom left of the screen.
6. Choose Wipe, then hit Factory Reset and then tap Yes to confirm the data wipe. Please note this process will not wipe your internal SD card's contents, so you may leave it connected to the phone. Now, return to the main menu by clicking the home button once wipe is complete.
7. Select Install, then browse and select the ROM file you downloaded in step 1. Confirm installation to flash it.
8. After the ROM is successfully installed, repeat step 7, but this time select the gapps-jb-20120726-signed.zip file and install it.
9. Once the Google apps package is installed, tap the Reboot system button to reboot the phone and boot up into the ROM. First boot should take up to 5-7 minutes and subsequent boots will be much faster.
The JRO03H based Android 4.1 Jelly Bean ROM is now successfully installed on your Galaxy Nexus.
