THIS POST IS FOR THE SAMSUNG GALAXY SKYROCKET SG2 LTE: MODEL# "SGH-I727" FOR ATT & "SGH-I727R" FOR ROGERS.

Thanks Goto lart2150 And cschmitt From This Thread, read the whole thread there and if you dont understand it then try this post.

I Decided To Make A Step By Step Guide To Keep All The Steps In One Post Instead Of It Being Spread Out Over Many Posts And Also For Newbs And Dense Members That Could Not Read The Original Thread Correctly.

My Phone Was Already Unlocked With A Paid Code From Ebay So I Could Not Complete This Procedure To The End.

All Info Was Taken From Above Thread, I Had No Hand In Making This Free Method Work.

For Newbs That Have Never Installed Custom Roms Or Custom Recoveries Read This First The Most Common Questions Answered Here Before You Proceed.
Theres A Learning Curve In Dealing With Android And As Such Basic Knowledge Of How It Works Must Be Learned.
If You're Too Lazy To Understand\Learn\Read Or In A Rush Then Just Spend The Damn $ And Buy An Unlock Code!!!

Thanx for a great post!

I applied for an Unlock code form ATT. They sent me one and it wouldn't work. I went thru about a weeks worth of goofing around with ATT and their codes never worked.

I used your method and I now have an unlocked phone, Thanx!

I also pressed your button a few times...
