Got yourself a Galaxy Tab 2 7″ P31xx and not satisfied with running just one build of Android on it? Want to dabble into custom ROMs like CyanogenMod 10, but don’t want to lose the stock ROM at the same time? XDA Member Macadamia Daze has found a way to dual-boot two Android builds on this tablet.
This dual boot method runs one Android build from the internal memory and the other from the SD card. Before you begin, you must have an 8GB or higher capacity SD card, though 16GB or more is recommended. Also note that the ROM you are running from the SD card has to be prepared to run that way. Fortunately, the developer has provided the latest CM10 nightly already prepped for the purpose, along with instructions on how to prep any ROM of your choice for booting from the SD card. For more details and the complete guide, head over to the forum thread and enjoy dual-booting two Android ROMs on your tablet!
Also, if you have yet to root their Galaxy Tab 2 7.0, we have already featured the rooting instructions for this device as well.

Perhaps you remember the days of the very first Android ports to Windows Mobile phones such as the HTC Touch Diamond and HTC HD2. Beside the fact that this groundbreaking development was one of the factors that ultimately led to the end of Windows Mobile development on XDA, it did bring some innovative features to the table. Dual boot for example. It was revolutionary to be able to choose between Android and Windows Mobile. After a few months, when people started to move to newer phones, and this innovation ultimately got buried under the huge
mess mass of development for Android phones.
It seems there is currently only limited active development for a dualboot system for native Android phones. There have been projects in the past, for example for the Samsung Galaxy S II, Droid Eris, Xperia Play and LG GT540, but it seems development is more focused on individual ROMs nowadays. Multi-device development – and yes, we use the word development a lot – is more and more subject to development on individual devices. In the past, developers collaborated to put together something great (Ervius Visual Kitchen, anyone?). The Android port to Windows Mobile, called XDANDROID, and the dual boot innovation are just few of the many examples of this.
Although it isn’t a bad thing that developers have a strong focus at individual ROM development, we probably all share the dreams of being able to boot into a clean, battery-saving and light-weight Ice Cream Sandwich ROM while also having the option to boot into another ROM, one that might be an experimental ROM or a ROM that is more focused on performance. Or any other combination. The open-source Android OS allows for many dramatic changes to be made to its structure, dualboot on Android has been proven to work on the Droid Eris, so why hasn’t development started yet? Why seems development of such innovative systems at a standstill? I say we fire up that innovation engine as soon as possible.

Every time we publish a story about the mods and developments on the Nook Color, it makes me seriously wonder if the Barnes and Noble people knew what was possible with the little ebook reader they were selling.
XDA Senior Member racks11479 has updated his multi-boot images for the Barnes and Noble Nook Color to include an SD image with both Gingerbread and Ice Cream Sandwich. Since the ICS build is semi-unstable and he still needed access to Gingerbread, racks11479 created this dual boot image for use on an SD card rather than the internal eMMC.
Following the SD versions release he put together a flashable version for the adventurous. Building the SD card requires the use of a partition manager and an image burner, but that’s a small price to pay to protect your devices precious eMMC.
If you decide to flash to your internal memory then, as usual, you take your devices future into your own hands. Check out the thread here to try it yourself and be sure to thank racks11479 for another great contribution to the Nook Color world!
