Google Nexus 7
JRO03D ROM based on Android 4.1.1 is available for Nexus 7. Digital Trends

A member of the XDA Developers' forum has released a JRO03D Android 4.1.1 (Jelly Bean) ROM for the Google Nexus 7. This is a significant release because the ROM is a stock Deodexed ROM.

The difference between an Odex ROM and a Deodex ROM is that the Odex ROM contains main files moved to another area for faster booting whereas the Deodex ROM carries the files that are compiled inside the APK. The benefit of having a Deodex ROM is that the user can customise the ROM.

If you wish to update your Nexus 7 with this ROM please follow below instructions. IBTimes UK warns its readers it will not be held responsible for damage to the device during installation. Ensure the Nexus 7 is rooted and ClockWork Mod (CWM) Recovery is installed. In addition, ensure all important data is backed-up and the battery has more than 80 percent charge.

  • Download Android 4.1.1 JRO03D ROM
  • Connect device to computer using USB cable
