[Q] How to Update PRL on Cyanogenmod 10.0 - Sprint HTC EVO 4G LTE

Hello ladies and gentlemen. First and foremost I would like to say that XDA is a wonderful community of which I am very pleased to finally be taking a part of. Since my very first Samsung Transform that I had back in 2010, to my Current HTC Ego 4g LTE I have used XDA and the resources that are provided here for all of my Android related questions. For that I want to thank XDA for having such a wonderful community and hope that things continue to devolp fruitfully for everyone.
Now onto the subject of my first post, of which I hope is appropriate in every manner.
I am running Cyanogenmod v 10.0 on my HTC Evo 4g LTE, TWRP recovery, S-on, Hboot v unknown currently.
Upon installing Cyanogenmod v 10.0 after much struggle I noticed that the 4g does not work. I checked my PRL and noticed that I am running 25015. So I began trying to find a method to update my PRL in hopes that this would allow the 4g to begin working. I have tried many different ways that I have found throughout XDA and Cyanogenmod forums to no avail. No dial codes work. Period. Please do not suggest a dial code because I have already gone through and tried every prominent variation. The next thing I began trying was connectingy phone to the computer and using the CDMA editor program(I cannot remember the name currently). The problem I ran into with this was entering DIAG mode. Again the dial code does not work due to the non Sense ROM. I have tried many variations of the Echo > 1 command but I cannot locate a DIAG file that this command would apply to. I have found a qct_ file but it is corrupt.
If anyone has found a method to put the phone into DIAG mode, or update the PRL using a different method that I have not mentioned your assistance would be greatly appreciated.
Thanks in advance.
I will update this post with more specific information on what I have tried when I have access to a desktop terminal.

You could make a backup, revert back to a sense Rom, update the PRL, then restore the backup.

^Easiest way to do it. It's always good to keep a Sense backup for updating profile and PRL, and for the occasional GPS fix.

I would like to figure out how to do so without flashing a new sense ROM. Until I get S-off I have to flash the boot.IMG if I understand this correctly. I had to do that when I flashed Cyanogenmod the first time.

Even so, I think it would be good to find a direct method to update the PRL and Profile in Cyanogenmod as opposed to simply working around it. That's no fun. I have beem trying to hunt down the file to change but to little success.

Definitely would be nice to know.
Is your firmware up to date? Only reason I ask is because your PRL is up to date and won't help you with your lack of 4G LTE.

My PRL is up to date? I thought sprints newest PRL was like 60xxx.
What do I look for in my phone info for my firmware version? If it is not up to date would that fix my 4g LTE issue on cyanogenmod?

You might need to call sprint and have them reprovision your phone, for that you probably need to be on a sense rom, flash meanbean which has a s-on installer then restore your cm nandroid... Good luck! I don't think there's other way to do what you need in aosp... :banghead:

Base band version: 1.12.11.1119
I enjoy trying to find new solutions to problems I encounter. I do not wish to take my phone to sprint and let them do anything to my phone. My phone is my baby.

Okay. You're a version behind. You need to S-off and update to the newest firmware version.
Take a look at the link in my sig and check out the link on updating firmware at the bottom.
