Need Help: Can't get 3G - Verizon HTC One (M8)

I have posted about this before but nobody was able to help. So I'm trying again.
I can only connect to 4G and 1x. So when I'm in an area that doesn't have 4g I don't connect to 3g but only 1x.
I'm running the Venom rom and I installed the Ota that came out in April.
I have tried switching the network type and it is set to "CDMA and lte/evdo auto".
Can anybody help me with this?

I never heard of this. That is weird for sure. Maybe try an run the RUU an go from there. Just a idea I'm throwing out.

This happened to me. I am using Viper Rom also. Basically when I was in my "home area" 3G/Voice would work great, but when I went out of my home area I had LTE only. So after several factory resets going back to stock without RUU'ing, the only thing that fixed it was RUU'ing. I then reflashed latest Viper Rom and all was good. Don't have any idea why it happened. You might try flashing just the radios from Santod Mods here:
http://forum.xda-developers.com/showthread.php?t=2723159 and see if that fixes it. If not just RUU and you should have 3G again.

First thing I would recommend is flashing stock recovery and doing a factory reset from it. Stock recovery resets some radio parameters that custom recoveries don't

Please help - Cyanogen Nightmare! Can't connect to cell network

EDIT: RIGHT AFTER POSTING, MY PHONE RANDOMLY STARTED WORKING. I HAVE NO IDEA WHAT I DID BESIDES POST HERE. MAGIC.
I installed Cyanogen version 7.2.0 just fine using the guide that was found here: http://www.mrmuh.com/2012/01/update-a-motorola-milestone-from-motorola-firmware-to-cyanogenmod-7/
However, the next morning I think I enabled the 2g/3g switch widget - and then my phone entered into a constant and continuous loop of "com.android.phone has unexpectedly closed" - and couldn't connect to cell service.
In a panic, I searched everywhere for fixes. I then tried a few of the fixes which instructed you to download "sqlite editor" and do some edits to the settings file. I did this, along with a couple of other network edits, resetting them to "0" instead of the "1" they were currently set to. No help.
Finally, I went into the Open Recovery system and did a full reset on cache/factory reset/etc. and then rebooted into cyanogen. Now my network won't even connect for a half a second and then crash like before - just straight up NO CONNECTION.
Now I've went through and attempted changing back some of those settings I messed around with in Sqlite - but to no avail.
Anyone with any ideas on how I can get an operating phone again, please let me know. I noticed I still have all my apps from previously, so I don't think I'm really factory resetting the phone. That could be part of the issue, I'm sure....I am very depressed and hoping for a miracle!!
Look into installing minimod recovery and then flashing the correct radio for your location after a full wipe.
If you do a google search you should find minimod. I'm on my phone or I would just link you.

OK Thanks for your reply.
However, randomly, just after I posted this - I looked down and my phone had a full 2G Connection. Went into baseband settings, enabled 850 band 3G, and now I have full 3G connectivity.
I have no clue how this happened. XDA forum is magical?
Thanks again for your reply, but thankfully I don't need the minimod suggestion as of now!!
You're welcome. You might want to go ahead and install minimod though. I made the mistake of not having it installed and flashed a new rom without the ability to select bands and was without a phone all day. It's better safe than sorry.

Good call. I'm just quite happy this is working now, but you are right, don't want that doomsday feeling again. Thanks
im having the same problem here :// i only can get cellNetwork if i restart with airplane mod.. then after i rebooted i go back to normal 3G/2G mode but otherwise i dnt get cell signal// also seems like wifi has some bugs im using HOHO CM7
Do a fresh install of HONO through minimod recovery.

Having radio problems

After flashing CM9 on my nexus s GSM, I no longer have any data connection or any connection at all for that matter, it detects that there are radios around but I cannot connect to any of them.
I have checked I still have the correct IMEI, and I have tried going to stock 4.0.3 and slim ICS, and 2 different radio drivers to no avail.. Also wi-fi works fine.
Can anyone suggest what I should do next?
edit: even tried going back to gingerbread... still no luck
Is there no advice anyone can give? I've tried so many things and i've run out of ideas..

Did you try to flash the latest factory image (4.0.4) downloaded from Google? It includes the radio, and after flashing it you would have your phone as if you bought it just now.
heres the different radio http://forum.xda-developers.com/showthread.php?t=1116884 or maybe the problem was the carrier??
try to figure out whats the problem?? or maybe you broke your signal hardware..
or maybe the problem was on the carrier??

CHeck your APN settings under settings>More>Mobile Networks and create a new APN unique to your own carrier. also, check if you can still make calls
I have this problem also when flashing cm7 months ago..
Solved it by flashing different radio..

Turns out somehow my phone corrupted my sim card after I flashed CM9, got a replacement, waited a day for three to activate the sim and it's all sorted now. Thanks guys
Wow. That sucks. At least you got it fixed and let us know!

How to get out of ROAMING? (after flashing 10.1 official)

So...I went ahead and flashed the Dec 24th official 10.1 release with data working. I flashed with TWRP and it went smoothly. I couldn't activate the phone because it was stuck in roaming. I tried what ever I could do but could not get out of it. So I resorted back to full stock from verizon locking and un-rooting. Did that and I also flashed a stock radio. Still cannot get out of roaming mode.
Any suggestions? Kind of in desperate need of data to get a working phone!
Thanks in advance. I'm sure this problem has come up among many of you.

I thought flashing "[OFFICIAL]CM10.1 Official Nightlies for D2VZW GSIII (12/24 Official Data Works)" was the latest one. How would I go about "fixing" the mobile settings? via the settings menu? I cannot access that menu if I need to go there. I need to get past the activation screen. Also I am not so sure on performing the four corners trick in order to get past that screen.
thanks

Gotcha. Did it and it seems to be fine now. Many thanks! Now I am hesitating going back to 10.1. I think i'll just stick to CM10 for now. until such time everything gets fixed.

i just posted a fix topic for this but here this is how i got mine to work after flashing CM10.1 the 12/24
If you remove ur sim card and boot up and connect via wifi, u can then register and set up the phone. then shut down put sim card back in and boot up. go to system settings -> More... under wireless and networks -> mobile networks -> CDMA subscription and choose RUIM/SIM (NOT NV)

I didnt see a responce from here but ill do my best, flash back to the stock ROM using ODIN and you should be put back into the operating system still in roaming mode then you dial *2767*3855# as soon as you hit the # your phone will download a file and re-provision itself which will fix the roaming error.

Latest 4.2.2 roms no service VZW

Has anyone else had this problem? No matter what latest rom I try, there is no data service at all. Even when I go into the configuration menu from the dialer and try to select the network, it refuses to do it. No matter what I do, my data will not work at all.

I saw your posts in the forums.
I'm having the same issue. CM10.1 from 7/17 works, but nothing after that does. I'm on page plus. What were you on when you flashed? I had to downgrade my radio to the ICS radio to flash my phone. I'm not sure if this is the cause though.
I should just have to set it as cdma & evdo to get it work but the radio never seems to turn on.

Weird ROM behavior, no data connection

So I installed bmm without issue, made my back ups and started trying roms. I had a hell of a time getting anything to boot. I would get stuck on the boot animation every time. Finally got slim kat installed and that is the only one I can reliably boot into. Tried aokp 4.3 which booted the first time but gets stuck on the animation now.
Also, when aokp worked I had no mobile data. Same problem currently with slim kat.
Where do I go from here? I've tried clearing cache and davlik on both with no luck.

Thanks, Wasn't aware of that. I copied my APNs from my stock ROM. I get data now, just not 4g for some reason. I'm looking around to figure that one out.

I only have the options of 3g and 2g with 3g already being selected. I don't know whats going on. My stock ROM gets 4g with those APN's, re-entered everything to make sure I didn't miss anything but I still don't have 4g as an option.

Type *#*#4636#*#*
Then select ''wcdma only''
Sent from my MB865 using Tapatalk 2
Well wcdma only didn't do anything. After messing with Slimkat and another 4.4 ROM (which only worked until I rebooted) I've decided that there are just too many bugs for me to use it daily. I decided to try a 4.3 ROM but I'm still having issues getting one to boot after the first reboot. I've let it sit on the boot animation for 45 minutes and it never loaded.
I haven't found a lot of advice on the subject of ROMs only booting once. Does anyone have any suggestions?

I realize this is an old one, but I thought it might be worth mentioning...
I had the same problem. When I copied APN data (specifically "apn type") from my stock ROM data did enable, but at a very slow speed. A quick search yielded this AT&T site which suggested different settings. I was able to choose the "ATT Phone" config and modify "apn type" from "default,supl,mms" to "default,mms,supl,hipri".
When I modified that value, data was much faster, but still only clocked 3.5 Mbps on my CM ROM vs 5.1 on Stock with SpeedTest.net app. I believe it used different servers and I only did a single AB test.
...and by the way - I am also a bit frustrated with the BMM setup. It seems like a third of the time I am unable to successfully boot back into my CM ROM. It always seems to boot into Stock ROM fine. I do have CM in the second slot which it sounds like some folks prefer to not use.
