[GUIDE] How to perform a BigPart Repartition Upgrade on your Motorola Xoom


How to perform a BigPart Repartition Upgrade on your Motorola Xoom

The Motorola Xoom is a very significant device as it not only the first real Android tablet, but it is also the first unnamed Nexus tablet. Even though the Xoom was well specced and future proof when it was first launched, its 1GHz Tegra 2 processor and 1280 x 800 pixel resolution feel aged next to newer devices.

While its dual-core processor and 1GB of RAM should still be able to handle Android, its stock partition layout is not allowing it to get newer versions of Android. According to Motorola there simply isn't enough space on the device’s /system partition to house the more recent versions of Android.

Fortunately thanks to the openness of Android, the development community have found a way around this limitation.

Senior XDA member realjumy (along with some help from Schischu and rchtk) were able to breathe new life into this device by creating BigPart.

Updating your device to the new partition layout is a fairly straightforward process. You must first load a new custom recovery. That recovery is then used to essentially perform a series of wipes and formats. And after all is said and done, your device will be repartitioned.

[UPDATE] [June 2014] If you face any issues with this guide, please for the source link at the bottom of this post for updated files/guide from the original source

[NOTE] It is important to note that once you change your partition layout, you must only flash ROMs that are compatible with the BigPart partition layout. Please download a compatible ROM before you continue.
