I seem to have signal issues on both ROM's. I'll give you guys a little background information.
I've used Fresh and Myn ROM's and always get perfect 3G coverage in my house and around town. Everytime I flash an AOSP rom I can't seem to connect to anything but 1X (if I'm lucky). When I was using the 2 previously mentioned Sense ROM's I'd have no issues with data. For the record I don't do a restore of my system data or apps when I flash because I prefer to download everything again to prevent FC's and other issues.
I've done a nandroid restore and updated PRL and Profile in a Sense ROM (2X) and then restored my AOSP ROM (ultimate droid) and that doesn't fix signal issues. My girlfriend has an Evo and she gets perfect signal on 3G (4G as well but she has it off) so it's not network related.
I downloaded the latest radio and pri from the development thread and flashed them in recovery. That didn't do anything at all and may have been a waste of time.
I then did these steps:
Dialed *#*#463+#*#*
Clicked on Phone Info
Turned off Radio (waited 1 min)
Turned radio back on
Ran ping test (failed because of no data signal). I can make/receive calls but nothing data related.
Is anyone having this issue? This has prevented me from fully enjoying AOSP ROM's and I don't know what the issue is. I'm using the latest PRL but could it be that my radio is broken? I would ready appreciate any help.
*** Update ***
I'm typing this thread on my phone and it's displaying 3G in full bars and then jumps to 1X full bars. It's kind of random but never steady. If anyone can please help me with this I'd appreciate it.
By the way I have an Airrave. Could that be the cause of my problems?

Same. i have this issue. although i dont get 1X. but i do however get spiking signal.
from what ive learned, the bars arent ur reception but how good ur connection is to the....satelites? aslong as u have 3G showing ur phone/internet SHOULD be working. although i would rather like to see all full bars where i normally would
i'm in a pretty high 4g signal area, but i love ultimate droid. i too have loopy 3g using cm6 or ultimate droid, would gladly give up my 4g to use either of these roms, but the 3g performance is way slower than on a sense rom. it's not just the bars, 3g on aosp is almost unusable, on sense roms, it works nicely
I solved my issue. The root of the problem is the Airave and how it connects with AOSP ROM's.
When I flash a Sense based ROM I don't have an issue with 3G and signal. I'm in a perfect 3G area by the way.
As soon as I disconnected the Airave last night my 3G signal came back with a vengeance. It hasn't left and is steady. I plugged in the Airave again and I saw my signal disappear and never come back. I could make/receive calls but no data access. I have the latest version of the Airave. Could someone (DEV) of an AOSP ROM investigate this issue. I knew it wasn't my phone because it would only happen in AOSP ROM's.

I finally got my phone replaced a few days ago for free (I broke my 4g and lost my rsa keys)
Before I rooted, my 3g had no problems. I made sure I updated my profile and my prl.
I rooted and performed a nandroid before flashing a rom
I flashed cm7 .. was running 3g just fine until it randomly stopped working. I've been Stucked on 1x...unless I decide to turn on my 4g. I'm not sure what's wrong..I've already messed with the roaming settings, host...making sure its cdma prl...restored my original nandroid ... still running 1x and extremely low speeds (.12 mpbs). It's not a tower issue (I live in fort worth tx..hurst area if that helps) as I've already tried different places and with another Evo that had no problem connecting to 3g. I reupdated my prl and profile with stock and no luck. Have tried several roms and no fix. Have also unrooted and went back to complete stock..no luck.
What could be wrong and how can I fix this issue? I really need my 3g back and I've ran out of solutions
Have you tried the fix located here: http://goo.gl/dTAXz
Posting & replying via the XDA Premium app
Wow man....that seemed to fix it for me. Resetting the ports and proxy...then restoring the data and doing the handsfree activation again (canceled the prl update)...though its weird I was on prl 67677 and after doing all that still am on 67677. Not sure how it fixed it but 3g is back...

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.
For the past week and a half, I've had internet issues when I'm on 3g. It works fine on wifi. I've switched between ROMs, kernels, modems, etc. I'm currently on Goodness with the MA6 firmware modem AIO and the anthrax kernel. I've tried updating the profile & prl. I have between 2-4 bars of 3g and yet it still gives me the webpage not available sign. I tried clearing the cache/ fixing the permissions. But the internet simply won't work. I'm in Maryland, between Baltimore and Frederick. What could the problem be? Maybe the phone itself is defective or Sprint's network died in my area?
I'd see if they're doing work i that area. I know in areas of Baltimore 4G is there, I believe. You could try using build prop tweaks ect for signal if you wanted.

Misery loves company.
The 2nd post is a thread I started regarding the same problem. The first post is to a thread I thought could help me. I tried some things mentioned in there but none of them worked. Then someone posted in the thread who is having the same problem.
Here's what I've been running into and what I tried. I am on FreeGS3, Anthrax kernel, and recently updated to MA6 when I started having problems. I use a battery saver so my internet connection turns off when my screen is off. I started noticing a week or so ago that when I woke up my phone, the 3g icon would appear but only the up arrow flashed. The download arrow wasn't doing anything. I would toggle it off and on and eventually get it to work. I'm in the Raleigh-Durham area and we are just starting to get LTE. My 4G works whenever I go through 4G areas and my wifi works. I have restored a working backup, wiped my phone, flashed back to stock unrooted, called Sprint (they refreshed my signal and had me do an OTA activation), manually changed my PRL, upgraded to MA6, updated profile (when I could get it work).........and I think that about sums it up. The one thing I've noticed is my phone works flawlessly when the network mode is set to CDMA. At this point I'm clueless. I really don't think it's a phone issue because 3g works on CDMA. It's like when the phone is set to CDMA/LTE and it doesn't have an LTE signal, it doesn't know what to do. That up arrow flashes in such a rhythm that it's like the code is stuck in a loop.
Put on CM11 Nightly (20131218) and I am having issues with handoffs from 4G back to 3G (although 3G to 4G seems to be fine). I can turn off radio and back on and everything is fine, but was wondering if anyone had a better idea about this?

official or unofficial build?
what gapps did you choose?
did you dirty flash or do clean install?

Official nightly
GApps 20131208
Clean flash (format /system, dalvik, cache, and data)
I've since gone back to 10.1 since it seems to be the most stable for data handoffs, but I would love to get KitKat going again.

I'm seeing the same problem with the latest snapshot (cm-11-20140104-SNAPSHOT-M2-toroplus.zip). I plan to switch to CM 10.1 for now, as well, since 10.2 still has known "Issues between 4G and 3G switching".
(wiki.cyanogenmod.org/w/Known_Issues_page_for_toroplus)
Any updates would be appreciated.

I updated from CM11 Snapshot M2 to the recently posted Snapshot M3. The 3G/4G handoff problems that I was having in M2 appear to have been fixed in M3. However, the (stock) portable wifi hotspot function isn't working properly for me now with M3.
After some additional testing I've found out that my signal cuts out and has problems reconnecting after activating the portable wifi hotspot (similar to the previous 3G/4G handoff problems). And the my other devices can connect to the portable hotspot but they do not get an internet connection. It appears that turning off the portable wifi hotspot and then toggling data may reset the data connection.
Is anyone else experiencing the same behavior?

I've been having all sorts of data issues lately, even worse I think with M3. But, I haven't cleaned flashed in a while. I hadn't thought to try toggling hotspot--I'll have to try that next time I can't get any data (3g or 4g). Over the weekend I had to hotspot my phone a bunch and since lte doesn't yet reach my house I had to hotspot 3g and that was working just fine. I'd be interested though, if you're consistently having good 4g data or if it was just a momentary fluke for a day. It seems like some days I've had no issues with 4g and other days it's been a bear where I struggle to even get 3g.

yotvb531, your suspicions were right... After 1 day of flawless data handling on CM 11 Snapshot M3, I experienced a hiccup during a 3G/4G handoff. Soon after, the data handoff problems became routine like they were with Snapshot M2 (perhaps worse). Although toggling the data connection would get the network to reconnect, the data connection problems occurred often enough to make me revert back to CM 10.1.3 a day or two later.
I'm now anxiously awaiting the next CM 11 Snapshot, hoping the data connection problems will be fixed.

After not being able to pick up 4G from the snapshot on, and hearing from others that they had 0 issues on a clean flash, I finally spent the 5 hours to clean flash my phone (I also formatted the sdcard while I was at it because I hadn't done that either in a very long time).
Happy to report that ever since then (12 days and counting) things have been very smooth. I've had issues only twice, but based on the behavior I'm pretty sure they are attributed to cell tower maintenance and not my phone freaking out...mainly because it didn't matter what I tried and then hours later after I had given up messing with settings everything started working again and was then fine for a week afterwards...and also after that outage the data speeds went from 1 Mbps to 8 Mbps.
Not saying a clean flash will fix everyone's problems, but it definitely did wonders for me...fingers crossed that when I finally decide to move on from the 2/13 nightly everything will continue smoothly.
There I went jinxing myself! I had to toggle airplane today after leaving work to get 4g to pick up. Was stuck on 3g EVDO. Toggling airplane mode got it to switch over to eHRPD which then allowed it to pick up the 4g. So maybe the hand-offs aren't perfect, but act fine most of the time--in my situations.
That same behavior happened once before on this same nightly (2/13) and I chalked it up as tower maintenance. That was in addition to the other time I mentioned where speeds jumped from 1->8 Mbps and I didn't have to do anything for the lte to return. I think that one was actual tower maintenance; just the other one wasn't...and it happened again today...twice in 14 days isn't too bad but it's definitely not perfect.

If I could get CM 11 to behave like that I'd switch right back to it. My problem wasn't that it would get stuck on 3G, it's that it would get stuck and not have any data connection until I either toggled data (e.g. airplane mode) or restarted. This would happen multiple times per day.
While I always clean flash, I never format my SD card. I assume this step has to be done separately from flashing, correct? Is it a best practice, or can just the Android folder (any others?) be deleted?

I did my internal storage wipe at the same time under advanced wipe in twrp (cache, dalvik, data, internal storage). I don't think it has to be done very often...I hadn't ever done it since the toroplus phone first came out so I had a lot of garbage and hierarchical messes all over the place (the 0 folder in 4.2 that was created...).
I doubt wiping the internal storage has any effect on the functioning of the data hand-offs; but I just don't know either.
