M3 custom release is clustered among the nightly builds with new features and customization options designed for specific Android devices, including the P3100 and P3110 models of Galaxy Tab 2 7.0.

Highlighted below is a complete guide for all users of Galaxy Tab 2 7.0 who wanted to upgrade to the latest Android 4.2.2 with CM10.1 M3 nightly builds. However, users should also note of the possibility of some minor bug issues to transpire, following the update due to the fact that these are nightly builds. Having this said, we at sebertech should never be held responsible for any issues that may transpire during or after the upgrade process. Also, be sure to verify your tablets meet the prerequisites before you begin installing the latest software update.

Pre-installation requirements to note:

1. USB driver installed for Samsung Galaxy Tab 2 7.0. This is necessary to connect your tablet to the computer.

2. USB debugging mode on the tablet should be enabled so you can connect it to the computer. Doing so will also allow you to utilize Android SDK with it. Here’s how to enable USB debugging mode on your Galaxy Tab:

a. Press Menu and then go to Settings.

b. Under Settings, locate and select Applications.

c. Locate and click on Development option. This is where you can see if the USB Debugging Mode is turned on or off. If it’s off turn it on, otherwise, leave it as is.

3. Backup all important data. Backing up of important files is a must before commencing the installation process so you can easily recover them later when necessary. Note that there is a possibility of the device’s data to be completely wiped out following this software upgrade process. Using an installed custom recovery like CWM/TWRP (if available) is therefore, highly recommended as it allows you to create a complete image of the existing set-up in your tablet.

4. Secure at least 80 percent of battery to have enough power so as to avoid potential interruptions during the update process. Errors usually occur when software installation is disrupted.

5.  Make sure your tablet is factory unlocked and not locked to a particular carrier.
