[Thunderbolt General] deathrow1993:
Ok everybody, after a few days of tinkering around with the help of many different forums and threads (sorry, i cant possibly start thanking individuals cuz i went through so many threads) i finally got my htc thunderbolt on PPC with 3g working. this is how

1.) remove the 4g sim card (if you have it) from the thunderbolt

2.) aquire all of the drivers you need for the thunderbolt and DM mode (hint, use htc sync)

3.) on the phones dialer dial ##3424# and press send

4.) hit the button that says reboot to modem+diag mode

5.) when your phone is plugged into the computer, has all the drivers installed, and is picked up in the device manager as 2 com ports

A.) The voice, text, and 1x com port is the htc diagnostic

B.) the 3g/4g com port is htc diagnostic 9k

6.) aquire a copy of cdmaws (2.7 is fine, there is a cracked version floating around, just use google no warez links

7.) open up cdmaws and connect to the non 9k port and connect

8.) go to the security tab and input your spc (000000) and click send, should say unlocked

9.) go to the other tab and under R-UIM Config make sure you select NV only then click write

9.) write all your nam settings, mdn, min, sid, nid, imsi and etc etc (other posts here at xda have all the details) repeat for name 2

10.) go to the other tab and under prl make sure it says universal and nam1

11.) click write and locate your pageplus evdo prl file (i used 51720) repeat for nam2

12.) go to the main tab and click disconnect but DO NOT CLOSE CDMAWS!!!!!!!

13.) connect the 9k port and repeat steps 8-12 but dont read, just write (all of your settings should still be on the screen)

14.) close cdmaws after all the settings are written to the phone

15.) find a copy of qpst 2.7 build 366 (again, google is your friend) and install it

16.) open up qpst configuration and click add new port

17.) find your non 9k com port click it once then click ok

18.) at the top go to start clients->service programming

19.) click ok then click read, click ok on the pop up that comes up

20.) go straight to the m.ip tab and create a new profile (or edit the one that shows up if it shows up) make it look like the screenshots i have below

21.) write the profile

22.) go to the PPP config tab and put *your 10 digit page plus phone number*@vzw3g.com for your nai and *your 10 digit phone number*@dun.vzw3g.com for teth. nai. password is vzw for um and an tab.

23.) close service programming and select the com port in configuration and remove it, close qpst configuration

24.) get a copy of dfs tools (demo is perfectly fine)

25.) see screenshots included at bottom of post

26.) make sure you start with the non 9k port, write what you need. and change ports to the 9k port without closing dfs tools, write everything to the 9k port (to be sure i pressed write for everything about 30 times but i may have been a bit excessive :D

27.) now activate the thunderbolt on your pageplus account by taking the last digit off of the imei number and they'll take it.

28.) insert ANY sim card into the sim card slot (NOT A VERIZON 4G ONE) i used a old nextel one to be honest :P

29.) turn on phone and dial *#*#4636#*#* and click phone information. change to cdma auto (prl) and close out.

30.) make a phone call and BAM 3g picks up and authenticates

Sorry if this guide isnt easy to follow, im not too good with wording things, lol. but it gives enough info for others to help including me.

also make sure under wireless and networks-> mobile networks-> that data roaming is allow for all trips, network mode is cdma only, and system select is automatic b
