this is the first and only root method that has worked for my T989D, ive read literally hundreds of threads from fellow S2X owners who all share the same problem, pcs not recognizing their device and/or not being able to go into download mode...well I wont say this is a guarantee but, I have tried literally everything every single person in every thread has said for advice and in the end, no one guide did the trick completely,but rather a mesh of a few.....1st, back up your phone if you can wirelessly through kies or another online file manager site. 2nd do a full factory reset with stock dialer *2767*3855#(cant be undone) 3rd download latest version of kies for drivers on PC and download necessary files from here:h t t p://mirror41.downloadandroidrom.com/download/GalaxyS2TMobile/rooting/tmobilegalaxys2rootICS.zip?token=800439833 where it says click to download, not on sponsored link, 4th. on phone,in stock dialer enter *#7594# and select "enable shutdown with long press end call" box . 5th, go to settings, then and more... select usb utilities, and press connect to pc,(without cable in phone) then it will say connect cable, do it and select usb storage quick before it disappears, once your sure the phone and pc are aware of each other(in your device list it will be labelled android and not under unspecified) and the icon in your notification isnt going away, hit dissconnect usb storage button and hit home button. 6th, hold down vol+ and vol- together first for a sec, make sure your holding right the middle, and then hold power key until vibration, immediately let go of power key AND AND!!! vol+ continuing to hold JUST vol- for another couple secs until download screen appears, and again same method when booting cwm, I was astonished when it worked, and all because of letting go of vol+ and power at vibrate, again thank you ten fold everyone who gave me tips!
