[HOWTO] Dual-Boot P31xx

view story

http://forum.xda-developers.com – Dual-booting has always intrigued me. I dual-boot between Windows and Linux on one of my computers, dual-boot between stock firmware and RockBox on my Sansa Fuze v2, and I decided to find out how to dual-boot my Galaxy Tab 2 7.0". It took a couple days of work, but I have found one way to do so using the external SD card. Warning: While I am not aware of any specific way this could brick your device, stuff happens, so don't blame me. I've tested this and found no problems, but you may not be the same. To use this method, you need a microSD card at least 8GB in size. If you use 8GB, tho (HowTos)
