It hasn’t been long since XDA Forum Member itsjusttim opened a bounty thread to get the AT&T Samsung Galaxy Note I717 hacked and working on Tmobile’s AWS 1700. It seems that it is finally a reality! XDA Forum Member tomin.fhl posted well documented info on how he replicated T-mobile 4G with three different modems: T-mobile SGH-T989 KID, T-mobile SGH-T989 VKL1, and Telus KJ3—all of them with full phone functionality.
You can choose between two options in order to hack your Note and get 3G/4G on Tmobile. The first one is the “easy” one, by downloading the modem you want and flash it through CWM. Or the more “technical” one, which involves adb and the dd command. You can find any of the three modem options for download on this thread thanks to XDA member tspx23.
The Galaxy Note must be rooted in order to proceed with this. The original poster has it running with the latest Saurom Projekt Team ROM and with the kernel that comes with it. He states that the phone works perfectly well. Remember, this is a process that will void your warranty and could turn your Note into a brick, so proceed carefully. In the words of tomin.fhl:
The AT&T Note was networked unlocked
I have been on T-Mobile for the past 3 years
I am on the T-mobile post paid 5GB Data Android Plan (with unlimited talk and text)
T-mobile sim was in the device while testing the solution
The Galaxy Note was rooted, and running the latest Saurom Projekt Team Rom with the kernel that comes with that rom (DA_G’s kernel I think).
The phone functions perfectly. My family called while I was testing and there were no issues.
Signal strength on my note was less than it was on my GS II. Indoors, I struggled to get two bars of reception.
I have yet to break 5Mbps download speeds and upload speeds are low, usually 1 Mbps or less.
