How To Upgrade Galaxy Nexus L700 to Jelly Bean Build JRO03L

  • First thing you need to do is just download Maddoggin Jelly Bean JRO03L custom ROM file on to your PC and transfer it to your Galaxy Nexus’ SD  card.
  • Next, switch off your device.
  • Now you have to boot into Recovery Mode and you can do that by pressing and holding Power+Volume Up+Volume Down keys.
  • And now you will enter into Fastboot Mode. As soon as you enter in this mode you can see “Start”. All you have to do is just use the Volume keys to bring to light “Recovery” and choose it using Power button.
  • And my advice is you should go for a NANDroid backup of your current ROM so that it can be restored back if something goes wrong.
  • And you can back up using the following steps – Go to –> Backup and Restore –> Backup –> Select Wipe data/factor reset –> Select Wipe cache partition and start wiping the data.
  • Next, Select Install ZIP from SD Card –> Select Choose ZIP from SD Card –> Browse for Maddoggin ROM file and the ROM starts to install over your device.
