Exclamation SOS. my phone stuck on EDGE

Since i changed a new rom(cm11) for my unlocked i747, I could not receive any hspa+ internet(I am using h2o). at the begining, i thought it was because of the lost imei, so i fixed it, but it was not working. then i opened *#*#4636#*#*, and selected wcdma perfered, it changed to h+, but about 1 min later, it turned back to Edge. if i select wcdma only, I can use h+ 1min and then no more signal even edge. also cannot make phone call and texting. i dont know why. the APN setting is right. and anyone tells me what should I do. thanks very much!

i had tried some other rom. i even regressed it to the originally official rom. it was will EDGE. I wonder the possibility is that some important files has lost. but i didnt find any solutions.

These seem like pretty routine questions but have you checked to see if another phone has the same reception problems?
