[Q] TMOUS ROM 3G data problem..

Hey Guys..
I had the hard work done, got s-off and had clockwork recovery on, but was having problems with wi fi/data knocking itself off at any times. Turns out it was a bug with the rom, so i decided to change to another..
and made a mess. Eventually i lost cwm recovery, was back to the chinese one and flashed TMOUS and eventually got it going. It looks and works great, except..
no 3g data. Wifi is perfect, gps is fine i think(latitude working) but no 3g connection, even though it says in settings that network operator is identified and 3g data is enabled also.
I reflashed a few times, same as. do i need to reflash a new radio?

[Q] No 3G data connection!

So, here's my situation:
I'm running a CDMA Gnex with Apex v.1.0.1 as my rom. I flashed a new radio, [Radio Hybrid] VZW EK5 CDMA(4.0.2) / EK4 LTE(4.0.3), in the hopes I could improve the hand off between 3G and 4G... Nope! The phone will no longer, no matter what I do, connect to the 3G network
OK... I figure, no big deal. I'll just flash a different radio set. Next up were the Leaked 4.0.3 Radios. Same thing. NO 3G at all!
Now I'm getting worried. I flash the stock 4.0.2 radios... Still cannot force it to use the CDMA network. I either have 4G data service or none at all...
What am I doing wrong? I've re-booted each radio set a couple times before dumping them for a different set. I've restored the nandroid back up from before I started messing with the radios. No fix there either. I've removed the sim card and reinstalled it (knowing full well it only controls 4G). Nothing doing...
I've seen similar posts about 3G/4G connectivity issues, but mine is strange because it's just the 3G radio that doesn't work. Voice calls and 4G data work fine.
Bigxie's rom has been rock solid, and since all the radios I've used presented the same issue, I'd be hard pressed to say it was one of them. I'm a noob, so I'm thinking user error somewhere along the line. Any help would be appreciated.
Update:
This was a CDMA network issue, not an issue with the Radios or Rom!!!
I magically picked up 3G this morning while at work. Since I was still running the leaked 4.0.3 radios and the Apex Rom, I realized that this was a network problem, not a software problem. I confirmed this with Verizon just now. They brought down the node closest to my place for emergency repair last night. The CDMA radio came back up as soon as it hit a tower that let it authenticate... It was just a coincidence that it occurred right when I flashed my first radio set, and frankly I feel dumb that I didn't see network error as a possibility sooner.

Try going all the way back to stock with stock radios and see if that fixes it?

flash the bootloader before the radio, reboot after flashing the
bootloader then flash radio, reboot, then flash stock.

[Q] No data after radio flash?

So after running into the bootloop problem since flashing, I got the appropriate (i thought) radio flashed and it fixed my bootloop issue. Now the problem I'm running into is i have NO data at all. Wifi works just fine but I can't get anything with 3G. Anyone have any ideas on what I should do?
EDIT: fastboot flash zip 1.09.01.0312_vivow_Radio_PG32IMG.zip is the command i used to flash the radio.

Upon further investigation and some help, I was advised to re-download the radio and flash it again. However, it had the same result. I even tried upgrading to the .0320 radio and I still have no data. The Mobile Data toggle on the phone keeps switching from on to off. Shows at least 3 bars of signal and then goes to the no bars with an X on it...
When I flash the radio in RUU, should the green bar go all the way across before doing a fastboot reboot-bootloader?
Again, any help is hugely appreciated!

And upon further investigation, I realize that I'm an idiot...... I forgot that I hadn't reactivated the phone yet....
*228 and the problem was fixed. Dur.......

[Q] Wifi not connecting at all on CM10

I had the wifi issue on 4.0.4 too, where my ion wouldn't connect to my wifi after it got disconnected but it would have worked again if I put my phone into airplane mode, disabled wifi, then turned it back on, took it out of airplane mode and reconnected the wifi, but after I installed the cm10 it doesn't connect at all it can't even find my network. I've tried adding the network manually but it still says its out of range. anybody else having this issue? has there been a fix to it ?

my wifi on cm10 working great, had no problem since i installed cm10.
maybe you can try re-install cm10, better do clean install, wipe data, wipe cache, wipe dalvik and format system.
hope it help you.

Well I figured it out it connects if you change the region code in the wifi settings and that's great cause there's no need to reboot the device anymore every time.

Low internet connection- switches to roaming mode

Hello,
Running ARHD 33.1 / stock kernel.
Problem: When my internet connection (not the signal strength bar) is getting low it tells me I am in roaming mode. For example: I'm in a room with very thick walls, it sometimes displays the 'E' connection and few seconds after I'm in roaming mode.
It happened for the first time when I flashed a wrong kernel (sense 4, but I was running sense 5). I was stuck on bootlogo, flashed stock kernel again and my phone was working, except this internet connection thingie... I was doing a full wipe, fastboot erase cache etc, reflashed ROM.. nothing helps.
I hope someone can assist me to solve this issue.
