A year ago, a line of next-generation Galaxy tablets was released by Samsung: the Galaxy Tab 10.1 and Galaxy Tab 10.1V. Soon after, another variation of the tablet was released, the Galaxy Tab 10.1N, sporting a metal frame over its sides and repositioned speakers. The Samsung Galaxy Tab 10.1 has been through patent lawsuits and sales bans, but developers are stopping at nothing just to bring tablet owners updates, tweaks, and custom ROMs.

With its default Android 3.2 Honeycomb OS, the Galaxy Tab 10.1 GT-P7510 runs smoothly, given that it has a dual-core processor. But, the fun doesn't stop there. Just recently, an alpha build Jelly Bean for the tablet was released by XDA Developers senior member MapleSyrup using the official Jelly Bean sources provided by Google. This is definitely one thing Galaxy Tab 10.1 GT-P7510 owners should rejoice about.

Keep in mind that this is an alpha build, purely experimental. A couple of things don't work in this build like the camera and aGPS. But, sooner or later, workarounds may be provided by the developer, so don't let those things hold you back from trying this build out. Just follow the requirements and instructions below to upgrade the Galaxy Tab 10.1 P7510 to Android 4.1.1 Jelly Bean.
