I have an unlocked Note that has Android 2.3.6 on it. I installed the Clockwork mod on it, and I flashed Tmo_SGH-T989_KID_radio_ATTNOTE (I have also tried 3 other modem files) to my Note. After the reboot, I see the 4G icon, but even though I am in a 4G area (San Francisco area of California), Speedtest only calculates that I get around 700kbps. I know you can “force” your phone to use T-Mobile’s 4G network (if you get bad T-Mobile signals like me) by switching to HSPA Only mode in Settings->Wireless and network->Mobile networks->Network mode, but even after doing that, I still do not get 4G speeds. Any ideas? P.S. - I have already tried the method here (but no luck): http://forum.xda-developers.com/archive/index.php/t-1547114.html P.S.S - I have also tried the Saurom (SAUROM_XLA2_RCVII) with T-Mobile Blaze modem (Tmo_BlazeModem_0331122), and no luck either.
