Samsung Galaxy Tab 7 users can now update their devices to Android 4.2.2 Jelly Bean. This update was made possible by the CyanogenMod team. The team has released the latest build of CM10.1 for Android devices. Samsung Galaxy S4 and HTC One were also included.

Specifically, the users of the GT-P1000 version of the tablet can update using the CM10.1 Nightly ROM based on Android 4.2.2 Jelly Bean. The ROM is based on the initially released Android Open Source Project. Based on reports, the developed AOSP promises a more stable and superior performance than the stock version.

Given that the Samsung Galaxy Tab 7 CM10.1 ROM available is a nightly build, users should expect some untested bugs and broken features. But rest assured users can find the fixes in these issues in the next updates for Android 4.2.2 Jelly Bean CM10.1 ROM.

Disclaimer: Some recommend against using the custom ROM to Android 4.2.2 Jelly Bean update. However, users can always choose to update at their own risk. Providers of the update have no control over what will happen to the device after the update.

There are things to satisfy before doing the update:

  • Users must ensure the model of their devices is GT-P1000. The custom ROM will only work with that given model.
  • The Samsung Galaxy Tab 7 should also be at least 80 percent charged.
  • USB debugging should be enabled on the Samsung Galaxy Tab 7.
  • Users should create a backup of important settings and data on their device. They can use either TWRP or ClockWorkMod.

Installation instructions:

1. Download the CM10.1 Nightly Build ROM for Galaxy Tab 7 P1000 [Filename: cm-10.1-20130504-EXPERIMENTAL-p1-cdesai.zip] and Google Apps [Filename: gapps-jb-20130301-signed.zip]
