My phone is 'samsumg s2 plus' i wana root my phone

Question

Am using samsumg s2 plus. I wanna root my phone. Suggests me best way.

Already tryed the www.unlockroot.com website. But I failed. Help me ..

@RossC / Yazz: Mind to create an answer with at least an abstract, so we can link this question from our index for future users? — Izzy, Commented Sep 16, 2014 at 15:58
@bmdixon Thought so. Also had to look twice. Luckily, our index has two questions linked on different S2 models, so I wanted to check which one it is – only then I noticed. Had there been only one link, I'd fallen for the same :) Nevertheless, we no longer dupe-VTC against the list. If it has a matching entry, dupe-VTC against that instead – otherwise, link it from there (which I will do now, as this one at least has a pointer – hopefully Ross will make his suggestion an answer soon). — Izzy, Commented Sep 16, 2014 at 16:01
@RossC Wow – that deserves an immediate +1 from me, very detailed – thanks! — Izzy, Commented Sep 17, 2014 at 11:04
