Not sure if this will help, but here is a shot. I found this info on the forums, but i haven't had a chance to try this yet.
I got these instructions from this post by kaeslumz

I modified these instructions a bit.
Instructions for QXDM 3.11.36:
1. Open EFS explorer from the QPST programs menu
2. Now click ok to select your phone and let it open up
3. Now exit EFS explorer
4. Open QXDM Professional
5. Go to options then communications and set the target port to whatever you use for QPST, mine was COM4
6. Click view and select NV Browser
7. Go to category filter and select data (as opposed to * all)
8. Scroll down until you see item 01192 "HDR Access Network Stream CHAP.."
9.Write down all the hex vales skip the first start with password 0-15
10. Now go to QPST service programming
11.Click read from phone
12.Then go to M IP Profile
13.click profile 0
14.then go to AAA shared secret and enter the hex values u wrote down do not use 0x00 just 00 and so on
15.now click ok
16.then click write to phone
17.then exit
to test if your evdo is authenticated..
##33284 and selecting debug info then HDR and all the way at the bottom it should say 1 = authenticated
If it says failed that means it didnt work and you might have to try again in case you made some mistakes in entering the hex value.
