Ok, admittedly a noob, but I've been trying for weeks to find some concise info about my EVO 4g Wimax issue(s) without much success. Rooted my EVO about a year ago but never flashed a custom ROM. I basically rooted (via unrevokedforever) solely to gain wireless tether capability. Noticed soon after root that my phone could no longer connect to 4G service (scanning....connecting....scanning, etc). I know many others have had this issue. I've since tried to troubleshoot this issue as best I can. RSA keys are intact according to the Market RSA key checker. Recently flashed CyanogenMod 220.127.116.11, everything works flawlessly except Wimax. Baseband version 2.15.00.11.19, so I don't think its a radio upgrade issue. My WiMax MAC address is intact (verified by taking out the battery, etc.) Any thoughts (Please!)?
