No 4G LTE connection after root

I rooted my thunderbolt using the ADB method and everything went fine until i tried installing CM7 1.4RC. I noticed that I did not have a signal at all even though I had upgraded to the 2.5 radio. I thought maybe it was the ROM so I tried MIUI and OMFGB to see if I could get it working. Even with the new ROM as we as every radio combination I could find I still don't have any 4G signal. Is anyone else having this problem or is this just me?

Initially had this issue. I resolved by going to settings , wireless & networks, mobile networks.access points, check verizon internet lte. This worked 4 me.
That doesn't seem.to work for me. Would going back to stock help at all?
Have you tried any of the sense roms?
Try taking synergy for a test ride.
2 me going bak 2 stock is a waste. Reflash 1.4 install goo apps and radio. After I did that I am getting a strong 4bars. 4g in atlanta.
i had that issue with my last phone....could not figure it out for the life of me. i tried everything. got a new phone.
I had this issue just last night..I found that there is a radio and an Lte radio that I had to flash. So maybe trying flashing a new lte radio.
I have been having this same issue...I updated the radio and got 4G last night. I then put snErgy theme on this morning and now I lost all data. Plus my WiFi is not working...which I heard is a common problem. I will try and reflash CM7, radio and see if that works.
Which radio are you currently using? Did you flash a combo radio or did you try to flash the coma and then the let separately? Try downloading the OTA MR2 cdma/let radio combo and see if that works.

What baseband are you on? Go to Settings > About Phone and check the baseband. You might be on the MR1 radio which will not work on CM7. If so flash the OTA MR2 radio.
1.39.00.0528w, 0.01.69.0602w_1 I flash the MR2.5 last night and it worked. But when I put synErgy on this morning...I lost data.
I flashed the MR2.5 radio this morning and I still can't get any LTE signal. I have tried the MR2 radio before but it hasn't worked but I guess I will try it again. Do you think that it is a problem with my SIM card?
Like mikeyflo said, definitely flash the LTE radio also. Fixed it for me

Do you have a link for it? I've search and for some reason I'm not finding it.
Right now my baseband version is "1.39.00.0528w, 0.01.69.0602w_1"

I can send a link after work..but there is a sticky in the development section that has Rome/kernels/radios and that's where I got it from..I just used the stock lte radio..it was the last link in the radio list

Found it and flashed...works perfectly now. Thanks man!
Can you link me the one that you flashed? I tried it and it didn't work for me but maybe it was the wrong one.
