[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.

[Q] i727 Network Drop after LiquidSmooth 2.5

I have installed 4.2.2 version of LiquidSmooth. But after installing it my network is dropping out within a min of talking. It's so annoying as I missed the most importing function. Talking to others using my phone.

What radio are you using? You should be using UCMC1.
Sent from my SAMSUNG-SGH-I727 using xda premium

I have a similar issue. I've been running the March 23rd version of AoKp with no problems. However, I recently tried to install the latest version and my phone will not connect to the Rogers network (connects briefly during start up, then drops, this trend repeats infinitely). Even when I do get some bars of connectivity, it never actually registers with the network, so I cannot send/receive calls, sms, etc. All other functions work fine. Also of note; after first reboot after installing ROMs, all the correct APN's are there and it seems to default to Rogers LTE which is good, however never actually connects. Then, after a subsequent reboot, all APN's are missing and I cannot manually add any (when I save them, they don't actually save).
I've tried installing the latest version of CM - same issue
Tried flashing different radios to no avail (running UCMC1 currently)
Luckily I'm always able to restore my backup to that March 23rd version AoKp which still works without issue. My next step is to revert back to stock ROM and either stick with that or try installing a fresh custom following that.
Any idea what the issue is???

I'm seeing the same issue as well on AT&T.
I tried reverting back to the regular Cyanogenmod Rom, but I'm seeing the issue where the radio keeps dropping and connecting back every few seconds.
I'm on baseband UCLI3. Is that the best version to use?

NO GSM after CM10.2 Flash

Hi,
i tried to flash cm 10.2 on my photon Q today.
I had the latest official rom working for half a year but i was missing some features i couldnt get with stock.
Anyway its a simcard modded unit i use in germany i was running stock jellybean (rooted, motochopper method) until today.
First i unlocked the boatloader, flashed latest open recovery and then flashed CM10.2 latest nightly (GSM) + gapps, after that i did a factory reset with open recovery.
After i configured the new firmware i noticed that i had no gsm, it didnt even ask for the pin of my locked card. I tried to switch from CDMA to GSM but with no effect. I also tried several reboots but i couldnt change the mobile network or get gsm to work.
I then tried to flash the latest cm snapshot but it doesnt work as well, the only difference is that the phone service always crashes when i try to change the network method.
Doesn anyone else have a idea? The thing is currently useless to me...
Thanks in advance.

Try this
http://forum.xda-developers.com/showthread.php?p=47978878#post47978878

i looked at the build.prop and those options except:
ro.telephony.default_network=3
dont appear in the file...
Also this talks about GSM Data problem, i cant even do phonecalls/sms, its not even asking for my sim code..
I then tried to flash back to stock but now RSD Lite 6.1.5 wont show my device... (all drivers installed).
Im really getting frustrated.
EDIT:
ok tried another PC with Win7 (mine runs 8.1) and now RSD Lite seems to work
Update: Now back to stock... GSM Works fine after i activated it... i now try to reflash cm10.2 and see what happens

Ok its working now
everything out of the box...
i dont know what went wrong the first time cause i did exactly the same as far as i know...

Indeed this line was likely the relevant one

[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?

My One won't reconnect to network after it looses signal

Hi there,
Everything was working just fine, but since I switched to a new carrier I can't get the network back as soon as my OP looses it (subway for example). I have 4G as my favorite internet mode and my APNs are good.
Only a full reboot fixes it, not even a soft one. What can I do?
I use the lastest CM 12.1 S rom (YOG4PAS3JL)
Maybe I should try to flash Oxygen's modem? http://forum.xda-developers.com/one...dio-updated-modem-radio-files-oxygen-t3072516
It seems many users are affected by the problem but I didn't find a real solution, hence my post.
Thank you!

After a long investigation, it seems that the OPO is having trouble switching for and from 4G. I solved it using 3G as my preferred network, but I'd have loved using 4G

reinstall the system... u can google fastboot images for opo... flash them through CMD

I've tried 3 ROMS and at least 4 modems so I think I've tried eveything that's available atm

I have had the same problem for some time now. But no reliable solutions found. Have tried various versions of ROM and Radio. Currently using 44S and CM 12.1 S (YOG4PAS3JL).

Didn't fix the problem. Finally reverted back to Oxygen OS. Complete reinstall, including bootloader, storage, everything. Got it done at OPO service centre. Much better reception now.
