Flashed OMJ's latest offering, 1.6 (without the radio), went to this thread,
http://forum.xda-developers.com/showthread.php?t=715485 , and downloaded the latest baseband and wimax radio, cleared cache between each flash (rom flash, radio flash, and wimax flash), updated my profile and PRL after the last flash (which was the wimax radio), and my 4g works! I now have a consistent 2-3 bars of 4g inside my house. Before this update, I only had 1 bar and it would not be a consistent connection. I have been attempting to get 4g working ever since Sprint came out with the latest OTA.
If there is anything anyone needs me to test out, please let me know. I have an EVO im using as a test subject. It has to go back to Sprint so I figured Id flash this bad boy until I found out how to get everything working.
