Re: Samsung Galaxy S2 (ATT) Rooting
The easiest way to root i think is usin the odin program, simply put the phone in download mode, selct the file in odin, connect your phone and click start and the whole process is done in about 20 seconds, as for the different methods of rooting, i guess that is down to the individuals personal preference. The Siyah kernel will root your phone when you flash it so i would use that method if i were you, using the odin guide in this thread but with the Siyah kernel: [url]http://forum.xda-developers.com/showthread.php?t=1309293[/url]
When you flash a custom firmware though there is a binary counter that records the amount of times a custom kernel/firmware has been flashed but you can buy a jig from ebay for a few $ that will reset this although the newer official firwares have blocked this from working, you can however flash an old bootloader (again through odin) which will allow it to be used and reset. Someone in the I9100 forums replaces the bootloader in the firmware so the jigs always work, not sure if anyone across the pnd is doing that yet though. Hope this sheds a bit of light for you though, so simple once you get going though.
