view story

http://forum.xda-developers.com – Hi ! I'm interested in root my sk17i with .587 without a custom kernel and without using the 4.0.3 stock kernel metod. I like to have the original kernel, but have root and recovery, It's possible for .587?? In dev section, I've only seen stock kernel with CWM and preroot but for .431 Thanks ! (HowTos)
