[Q] No Internet when flashed

Apologies if this is a eally simple question - but i did search for an answer.
I flashed at first to DeFrost 6.1 but wasnt getting any 3g, Edge, or H showing on the phone - only the signal bars. I assumed this was maybe a problem with the flash or something so did it again and still the same problem.
Now flashed onto CyanogenMOD 6.1.1 and its still the same. Do I need to add some other file to enable this?
Cheers.

Have you checked the APN settings as these will need to be configured to your network provider?

[Q] Problem with data network - DHD

Hi guys
I have problem after rooting DHD with AAHK with gprs/EDGE data and 3G data. GSM works fine, WiFi, GPS also but I cannot turn on data over mobile network. Tried different ROMs, flashing different radio versions, return to stock rooting again and still nothing. Tried to change APN settings, pull off the battery also but no luck. Also I tried with *#*#4636#*#* to switch radio off no luck. Is there any way that I can troubleshoot this to find out what is causing the problem. My radio version is
12.56.60.25U_26.10.04.03_M
Sabsa Prime V8.0 - tried CM7.2, stock, Revolution HD, Jelly Time, Pacman Jelly... no luck
Thanks in advance for any help

I think the problem is with your APN settings. Something like this happened to me recently and it was because my APNs were messed up. Try this app to save your APNs. Maybe there's some error in what you're manually entering. I see no other reason as to why your mobile data shouldn't work on any ROM, especially if you're getting a signal.

Thanks on your reply. I found that the problem was with my operator, because they disabled the data service for my account. I thought that problem is with my phone but it was on their side. Thanks again

[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.

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.

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
