[Q] No 3G connection with Cyanogen CM7 Gingerbread

This question should probably be in the thread for the rom.
The 3G connection is not working with Cyanogen CM7 build 32.
It was working with leedroid 2,3d.
Anybody got a clue?

Too bad that i need 10 posts before i can ask that question in the developer thread and report bugs.

I just flashed the latest radio without any better results.

This thread is correct to stay HERE..NOT in dev section, thats why the 10 posts rule
U should open a thread in dev section only if You developed something..
About the 3g connection, it works fine on my phone on latest cm7...maybe poor connection in ur location, i dont know

That was not an alternative. But i received a bootloop on the phone after installing a theme. Full wipe and clean cache + dalvik.
Then it works!

It´s working now after a clean of dalvik cache and manually set APN under network settings.

Doesn't Cyanogen have it's own forums? Surely you'd be better off there?

I was not able to make posts in that thread before 10 posts on the forum.

Same issue.
I am having the same issue. What do you mean by "manually set APN under network settings."?
Thank you.

Some APN settings from CM7 are not correct. You might need to manually enter these settings. You can usually find your carrier's APN settings either on their website or by calling them.
In CM7 go to settings, wireless & networks, mobile networks, then Access Point Names. You must delete anything listed by clicking on each one individually then clicking menu and choosing delete. Then you can add your settings by clicking menu then add on the main access point names screen.
Hope that helps!

APN
I added the apn manually and it fixed the issue for me. I had the same problem on leedroid btw.
Thanks.

I'm having the same issue, I was going to try and clear the settings but in my ver. of GB I have nothing to clear, it list, "Data enabled" "International data Roaming" National data roaming" and "System select, Home, Affiliated, auto"
The first three are check boxes only, nothing else, is there another way to reset?
Thx

I also had 3g problem with defy and cm7, Fixed
I found an app in the app drawer called baseband switcher. I simply had to open the app, set it to US Tmobile and reboot. I set the default apn to tmobile and now I have 3g/hspa.
Of course I didn't notice this baseband switcher app until after I wiped the phone twice trying to fix this issue
I hope I can save someone else the time and hassle of reloads and reboots and apn renames.

[Q]Cant send MMS

After i flashed 4.0.2 radio, i cant send mms anymore.. I got the apn from my mobile provider (Telenor), but its stuck on "Sending"...
Any one ?

Is mobile data enabled? Do you actually have a data connection? Unless your provider gave you the wrong information.

I still have lots of problems sending MMS. 4.0.2 running Android Revolution 2.1.2, with the leaked 4.0.3 radios. It was a problem when I was still 100% stock, too. Pretty bothersome.
3G, WiFi (which I'm pretty sure isn't supposed to work with MMS anyway), nothing. Sometimes when I reboot and retry sending it will go, but mostly just sits in sending mode forever. Frustrating.

Might just have a defective phone. Go back to stock and lock it up and take it to your phone company

go back to your previous radio? or pick another to test.
btw, radios are location and carrier specific..
which is why it works better for some an not others..
ppl should stop referring to radios with a link to rom versions..

No data after flashing a new ROM

I have a Galaxy Nexus with Android 4.1 using Simple Mobile (T-Mobile towers) but every time I flash a new ROM, my signal bars go gray And I get no data ( MMS, Browser, etc. )
It has to be something simple that I'm missing. What could it be.
I made a backup so all is well but I just can't upgrade.

Have you checked to see if your APN is configured properly after flashing?

I'm writing down all the APN settings now. I'm gonna flash and make sure these settings are correct.

[FIXED] Mobile data doesn't work with custom ROMS

Hello,
I purchased the new Nexus 7 LTE last friday. The very next day I unlocked, rooted, and installed the ElementalX kernel (with the stock ROM) . All worked well.
Sunday I tried installing a ROM (IceCold). It ran fine, and I was on wifi, so everything was working. Until I go out of my house. Mobile data was not working at all. I later reflashed stock, and did a factory reset. Mobile data worked again.
I thought it might just be the ROM, so I decided to instead flash P.A.C Nightly 4.3.1 with default kernel, and again, same issue. The mobile data icon is grayed out, unless I connect to wifi, and then it goes back to the blue color.
I have tried everything I could think of:
Restore stock recovery, kernel, and ROM.
Help would be greatly appreciated. Thanks ya'll.

Bump
Does no one have the same problems? Could this just be me missing something?

You are probably using a rom for flo Devices that do not have lte or 3g connectivity. Only use roms from the "nexus 7 (2013) LTE Android Development" forum!

It could be that the custom ROM you are trying does not include the APN for your carrier. Go to Settings -> More -> Mobile Networks -> Access Point Names. You will need to find the correct APN settings for your carrier. You could copy them down while you're on stock, or look them up online.

No, I checked this. The first ROM I tried installing wouldn't install because of it being for flo devices. However the next two were both made for deb devices. So that wasn't the issue. Thanks though.

This does make a lot of sense, could it be it's not reading the Sim correctly perhaps? I'll be sure to try this when I get the chance.

Most APN settings are easily found with search of the carrier name and APN. You may have to enter these manually.
Did you try mobile data before rooting and installing a ROM/Kernel?

Data worked before during stock, and when I had a custom Kernel with the stock ROM. So the cause definitely had something to do with the ROM. After I reset everything (relocked and unrooted) it still works. I am redoing the unlock and root as I type this, and I will hopefully get a ROM installed and check to see if the APN settings really were the problem

Well that's good news. The only reason I asked was to make sure it wasn't possibly hardware related.

Note 2 No data coverage after 4.3 update?

Just upgraded to 4.3 today but my data services don't seem to function well. Can someone please help me?

Same problem here..

Looks to be an issue with TWRP, have either of you tried the latest CWM recovery? I was hoping to avoid it since my nandroid backup was TWRP (I'm honestly not sure if there's a difference) but a few posts in the main threads are reporting a similar thing.
EDIT: Nope, same issue, at least for omnirom.
I take that back, it does work.

Go to Settings - Network Connections - More Networks - Mobile Networks - Access Points Names
Check and see if you have the APNs from your provider, they usually are 3 ([Provider] Internet, [Provider] WAP, [Provider] MMS - in my case). Make sure [Provider] Internet is selected. When I usually re-install some ROMs, the WAP APN is selected by default and that will show me the 3G data icon but it will not let me access internet resources with my data services.
If by any chance you are missing the Internet APN, search a bit on the internet for your provider APN settings for internet access.
Hope this works.

It just acts like there's no SIM card at all. I don't understand it completely, but CWM is doing something that TWRP is not (or vice versa) and is causing this issue. Took my 7105T from virgin vanilla stock to the omnirom 4.4.2 nightlies yesterday and when I flashed from CWM the issue was resolved.
That said though, I'm unsure how this will affect omnirom's updates so I might need to switch to cyanogenmod. Shame, because I do prefer TWRP.

I don't know what you guys are talking about but I can't even access the APN settings, its invisible. I have a SCH R950 note 2. H2o wireless already took my money but told me I needed to unlock it, even though I can't unlock a CDMA phone. im so confused because it is quad band and has sim card slot but no one can unlock it and I cant find how to flash to h20
