[Q] No data connection with any Jellybean ROMs

Hi,
I recently decided to flash a jeallybean ROM since most of them are getting really great and we don't have any word on the official update. Unfortunatly, I'm now unable to get a data connection on my HOX. It's the rogers version which I unlocked and I'm now using on the Bell network. Before flashing, LTE worked fine with the stock sense ROM, but now I don't have any data at all.
ROMs I've tried :
AOKP, MIUI and CM10.
I've tried to : set the data connection to GSM only, nothing, to LTE only, nothing, to WCDMA only, nothing. I've tried all the APNs I've found (pda.bell.ca, pda2.bell.ca, inet.bell.ca). On AOKP it sometimes said "Error while searching for network". WiFi, texts and calls work fine.
If anyone could help me, it would be really appreaciated. Otherwise I'll just revert to Rogers ROM. Thanks alot!

I cant offer any help, but I'm having a similar issue recently. I was on a nightly build of CM10 (from 10/06/12 I believe). I upgraded to a newer build (from 10/10) and I get no data over cell. I flashed it back and things were fine.

Before flashing jelly bean roms you need to flash a sense rom then do full wipe and install cm10 or aokp..

I have the exact same problem with my SGS using the X-bean 3.0 rom.
What's the best solution? Is it because I used to Cwm?

Every device has its own nuances, as do various ROMs. So I'd advise posting this in the forum specific to your device.

Still no data connection.
I am having the same issue with my AT&T One X phone.
The phone was running 2.20 before it was unlocked/rooted. Installed TWRP, was a noob and forgot to save a backup, fastbooted the boot.img, flashed AOKP and CM10 successfully. With both of these ROMs, I could not get internet to work via cellular connection. I have tried everything with the APNs (even had AT&T help me setup APN settings) and still no mobile data connection. I can still receive/send SMS/calls, use bluetooth and wifi, just no mobile internet.
I'm not entirely sure what to do next. I attempted to go back and flash the UrDroid 4.1 Stock Sense ROM, but after fastbooting it's boot.img and attempting to flash with TWRP, I got a signature verification failure. Got scared and restored back to AOKP (I remember to make a backup this time.)
Thoughts? Sorry for being a noob.

Are you in an LTE area?

I am in a "4G" area (HSPA+) but I am also a hour drive away from LTE. I have tried APNs for both, but AT&T recommended I stick to the LTE APN. AT&T had me go to Settings->More->Mobile Networks->Network Operators and the phone just sat there searching without finding anything. I just did that above operation again and it found AT&T and I selected it. It spins on "Registering on AT&T..." for a few minutes and eventually errors out "Cannot register on this network at this time."

Have you tried switching off LTE by selecting "GSM/WCDMA Auto" in Settings?
I've had data problems on certain ROMs, where turning off LTE got the HSPA+ connection working.
In that case, it was probably a base of build.prop not playing well with AT&T's network. Although I would think the ROMs you mentioned would have these issues worked out at this point (and for some time now).

When I switch to "GSM/WCDMA Auto", it immediately switches itself back to the LTE setting. This is concerning.

Phone stuck on "Activating... " after installing slimbean

Like the title says, my phone will not activate. I was using liquid smooth 4.2.1 beta1b. It was running flawlessly then I saw the slimbean 4.2.1 beta release and did a clean flash. When first turning on, i selected english then went to the next screen where it was stuck on "Activating... " and never activated. I booted into cwm and my backups disappeared, so i reinstalled liquidsmooth and got the same error. So then I figured it was my modem so i installed vrblk13 (i think it is... the newest one), rebooted and got the same error of not finding service. So after this I odin'd back to stock jelly bean, still no service. What could it be??
Do i need to odin back to ics or something? Im so lossed at this point as to what it could be. Settings wont even show my number as if the sim card isnt in, but it definitley is as ive taken it out and put it back in..
Any help GREATLY appreciated

After you attempt to make a call, which won't work.
Go to Settings.
Mobile NetWork
CDMA Subscription
Switch from NV -> RUIM/SIM
Reboot.
Try to see if you can make a call.

Thank you very much, that did the trick. Any chance you can explain what that did, and if i went back to 4.2 if it'd make it work? (im back to 4.1.2 pa

It flipped the phone from using MEID based authentication to RUIM authentication ( the LTE sim)
The same thing happened to me when i flashed cm10.1 I originally thought it killed my imei.

[Q] Service is toggling after flashing JB on i727

I have two questions 1) is my only way to fix this to go back to stock ICS using ODIN? 2) Once i get back to that, what do i do in order to get to a working version of JB? is it as simple as trying another ROM? Is it ok to skip ICS and just flash another version of JB?
Background if you want it....
Followed vincon guide : http://forum.xda-developers.com/show....php?t=1773659
Started with Stock ATT 4.0.4
CWM via odin
baseb: UCLI3
I flashed JB [ROM] [4.1.2] [UCLL3] Stock Debloat to my i727 last night. Everything went seemingly smooth, everything worked with a strange exception being my exchange account wouldn't authenticate.Today my service is off about 95% of the time, then it will come on and ill get a text or two, then it goes off. voice calls dont work at all. LTE data is hit or miss.WiFi works
In phone status under network type its toggling: UTMS:3 to HSPA:11 to HSPAP15 to no service...then it drops everything and service state will say out of service and disconnected.
My IMEI is correct, I confirmed that.
It tried dialing the *#*#XXXX#*#* thing, that just said no connection and ended.
I started to go down the path of looking to flash a new radio, but that just doesn't seem like the answer to me... obviously the risk of me being wrong is high. i did check the MD5 numbers on other radios though and they came back as mismatched, so i did nothing there.
Also i wiped cache 3 times, as well as dalvek
Is there a simple solution that Ive missed or do i need to go to stock via ODIN? What, if anything, did i do wrong>

If you didn't flash corresponding UCLL3 baseband - AFAIK intermittent service is expected.
If you need to flash baseband - flash the latest UXUMA7 baseband.

Well i've actually had the exact same problem, in several variations and on several androids and here's my conclusions:
1 Magnetic storms and grid issues with the carrier. There's not much to do about these, except maybe for a making a tin hat for your phone. But, on a second thought this would also kill the signal
2 If the issue persists for more than a couple of days then the other thing for me was = radios that just didn't work with my carrier or rom. Changing these showed instant results.

I actually had this exact problem but for me it was on the carrier end. I tried every ROM and radio out there to no avail. After about a month and my parents also experiencing the issue, we called the carrier and they had it fixed in about two weeks.

[Q] Lost all data/mobile connectivity after flashing CM10.1.0.1

I am also having the same problem I went from MOAR rom to CM 10.1 and my phone says roaming. I try to call and it tells me to call Verizon. SO I went back to MOAR rom and I still have the same problem

Same issue here. Had to restore to previous.

Check Q&A and Dev threads.
The .1 breaks data. Either go back to release, RC5 or go to Nightlies.
I went to nightlies and i'm working fine now. (and get the new features)

My problem is I flashed back to stock via odin and I still have no data, at all. It's roaming...Will attempt to reflash tonight.

Alright I'm on the latest OTA build, MF1 I believe, still roaming only. Where should I go from here, what should I flash to hopefully get rid of this. *228 doesn't work. *2767*3855# says my phone is not authorized to make this call, etc...I'm stuck.

Nevermind, I did a full reset and have all my data back. I'm on the latest OTA, can I root, unlock, and proceed as normal from this build?

[Q] Cannot acquire data connections

I'm having an odd issue. I've been running the latest Hyperdrive ROM release on my S3 for about a year now, but I can't stand Touchwiz ROM's so I've tried flashing AOSP ROM's such as CM, AOKP, even Beanstalk. I love all of these ROMs for tons of reasons but I keep running into the same problem, everything works great but I can't receive mobile data. My mobile network state is Disconnected and I have no idea how to fix that. I can text, call, and connect to wifi fine, but no mobile data. I've backed up my EFS but I'm not sure that's connected to the same thing. I have the network set to "CDMA/LTE" (would be more specific but each ROM has it different), but for whatever reason the APN settings are inaccessible. The menu option is clearly there but I cannot open it to ensure I'm using the LTE APN. I decided to give this another go yesterday, and still no dice. However upon restoring my CWM backup of Hyperdrive, I have now lost 4G and am stuck on 3G. My network type now shows eHRPD and while I can access my APN's (I was always able to on Touchwiz ROMs) I can tap on the Verizon LTE APN, but it seems to make absolutely no change to the actual APN. In fact when I reboot it it defaults back to eHRPD all over again.
So, 1. have I somehow screwed myself over? and 2. what am I missing with AOSP based ROMs?
Thanks for any and all help.

I would try flashing a stock ROM such as the one on ScottsROMs.com
The 4.3 stock rooted, OTA disabled, UNlocled boot loader and no Knox.
See if you can get data with that. Firmware for the radio may have gotten messed up, and this would re-write that data (long shot, but worth a try). Another option would be to re-flash the radio maybe.
And now that I think of it, which radio are you on? MF1, ML1, NE1? Because I think I read somewhere that certain ROMs require a certain radio newer than _____ (don't remember which radio).

Thanks for the help. I flashed a 4.3 ROM as you suggested, and no difference. I then chased some threads around and decided to just factory reset it as if I was going to return it. Still nothing, I get 3G, not LTE. I was using MB1 before I flashed an AOSP ROM, at which point I flashed the MF1 firmware and then the ML1 modem. That did nothing to fix my issue. I'm not quite sure what else I can do at this point.

Hmm... ML1 should be new enough.
That's a bizarre issue.
For me, I mainly get 3G. It seems as if either Verizon pulled some LTE towers near me, or my data antenna doesn't have very good contact. Maybe you're having the same issue.
Do you EVER get 4G? Or literally never?
