Not connecting to 3G EVDO, only 1xRTT

Hi, I was hoping someone here may be able to help me out with this problem. Last week I had a weird issue where my GPS signal stopped working, text messages and phone calls weren't coming into the phone. I've since been able to correct that issue with flashing to a clean Sense based ROM, and updating the profile and PRL, but now I can't seem to pickup 3G EVDO signal, only 2G 1xRTT..
My phone is(was) rooted and flashed with Calkulin's EViO 2 v1.77, most current radios. I thought maybe something got messed up, and since 1.8 was out, I flashed to that. Same issue, updated the radio from his package, same thing. Then I thought, ok, maybe something with this rom is messed up(unlikely, but I was grasping at straws at this point), so I flashed to a different rom, think it was sprint lovers.. same thing. Flashed to CM7, same. Unrooted and flashed back to stock, took it into Sprint, which they did a hard reset and told me since it shows the 3G icon in the top bar, it is on 3G and working fine. This is ofcourse bull**** since the Evo shows that 3G icon even if its on 1xRTT signal..Sprint tossing out wrong info, shocking I know. I've used Antennas and OpenSignal apps to show that it is indeed connecting to the 1xRTT signal. Downloading anything on the phone is ofcourse slow too, I've had google maps updating now for about 15 minutes, and it is 5.86MB.
Would anybody have some suggestions of what I can try to get the 3G radio working again?

Anybody have a suggestion of what I could try here? I've changed my PRL to the Verizon one, which gives the same results. Still having the same problem.

ya its calkulin's 1.8. the new extended mobile data menu hack has a messed up default that sets it to evdo only by default, messing up everything else. switching roms doenst help. go back to calk's 1.8 and type in the dialer ##3282# select view only and make sure mode of operation is on automatic.

[Q] phone will not let me do anything while roaming. any ideas?

so i was running the VR_GengerSense_Revolution_B4 rom about 4 days ago with now problem doing ANYTHING on my phone while in digital roaming. then i left the roaming areas and went into sprint service area and came back into the roaming area and now my phone wont do anything while roaming. i cant make or receive calls or messages or use any apps or the net. i have 2-4 bars of signal but if i try to do anything it tells me i have no network connection. yesterday i switched to the BeKinged-STOCK-Beta-V1-Clark44 rom thinking that changing everything would fix it but it didn't i went back into that same roaming area today and its the same story. does anybody have any idea of what i could do to fix this? I'm at a loss i tried every setting and was on the phone with sprint for about an hr. and nothing. Ive tried different radios and still nothing. i was thinking of un-rooting and seeing if that changed it. it baffles my that it just randomly started with out me changing anything on my phone.
thanks for any input.

i updated the PRL tonight hopefully that will help \. gonna try that before i un-root.

PRL update didn't help. unrooted taking it to sprint tomorrow.

[Q] why can't I make phone calls?

For some reason randomly when I try to call someone it stays at dialing even if I have good signal. I've tried restarting multiple times and trying any profile, and prl update but to no avail. I get data no problem but on 3g with 5/6 bars I got .40 mb down and .13 upload... Is anybody else having these issues?

[Q] Data stopped with 3G Signal ON

Hi, I've been following xda for a while but just recently registered. I searched the forums but didn't find any good answers/fixes.
In either case:
I've lost connectivity on my HTC EVO 4G. It's odd because the 3G signal indicator shows strong and the up/down arrows light up/dim. I'm running the latest CM7 supported nightly build and the Tiamat Kernel.
I was running a PRL for Verizon only roaming but heard rumors that 4G was in Phoenix. I did a backup of my ROM and restored a default android one then did the PRL update through the phone to get the most recent PRL from Sprint. Now in my CM7 rom and regular android ROM I can't connect to any data.
I tried re-wiping caches and restoring a second time to no avail.
Maybe I broke something in the ROM and just need to do a factory reset? Not a problem if that's necessary I have backups of all my stuff.
Any help for regaining service would be great! Thank you in advanced.

Well never mind I guess... just my luck as a Sysadmin once I ask about why it's broken it's fixed.
All data is back on my phone even after multiple reboots. Maybe PRL update didn't register on Sprints end? Don't know...
Thanks anyways everyone!

Happing to me too, it's a tower problem in my area. Nothing to do with your phone just Sprint's crappy network.

[Q] No 3G data

I am currently having issues with my 3G data, I have full signal and get the MIPS: 316 error, data connection cannot be established. It all started when I my GPS stopped working and the solution I found was doing an NV Rebuild. After I did the rebuild my GPS was "OK," but not great. I noticed when I was on 3G data it worked great and fast, but on LTE it was awful. I ended up dealing with it for a few days and did the NV Rebuild again, but this time when I booted I had no 3G data connection, even with full bars. I tried flashing several roms. I was on CMRemix 8.6, 8.7, 8.8, then used Hybrid X-Series v2.3 and Hybird I-Series Alpha v2. Nothing worked. I ended up flashing stock last night hoping it fixed the issue, but nothing has worked. I did the PRL update and the Profile update, nothing.
Does anyone know how to fix this issue?
Thanks!
