CyanogenMod 10 gave a great way to get the taste Jelly bean Android on your Tablet unofficially. Right now, only few tablets like Asus Transformer, Motorola Xoom have got the Jelly bean update. Samsung Galaxy Tab 2 devices are the 3rd Gen Samsung Tablet but yet Samsung has not taken any initiative to provide the Android 4.1 update. All thanks goes to XDA developer member codeworkX who has informed us about the Android 4.1.1 Jelly Bean port for Galaxy Tab 2 7.0. The ROM is working on GT-P3100, GT-P3110, or GT-P3113. The ROM is working fine but there are few minor issues like Touch do not respond at lock screen [happens only in rare case], Home screen is always in landscape mode and cannot be turned into portrait mode. I am sure that developers will resolve the issues very soon. We also got some leaks that Samsung is creating Jelly Bean 4.1 update packages for Galaxy Tab lineup. But still we need to wait for Official announcement.
- In order to proceed with this upgrading process you need to root your Galaxy Tab 2 7.0 with ClockworkMod recovery installed on it.
- Backup your precious data, apps and settings on your device such as contacts, SMS, MMS, APN settings, MMS settings, Wi-Fi passwords, images, videos, music etc just to make sure that you have kept them safe somewhere.
- Check for your device battery whether it is charged or not. It is better for the device to charge it’s battery to at least 70% before engaging in any kind of update process. Otherwise, your progress will get interrupted by turning off the device.
- Please enable the USB Debugging option on your Galaxy Tab 2 just through the path ‘Settings > Applications > Development > USB debugging’ and checking the option box for USB Debugging.
- The security suites like firewall, antivirus etc must be disabled on your computer and device so that it will no longer be able to interrupt the process.
