No 2g/3g/lte after flashing rom - ONE Q&A, Help & Troubleshooting

Hello, I have this weird problem, which i also had on my old galaxy s4(i9505).
After flashing android L rom, I have no data. My wifi works perfectly, but my data is gone. I can send/receive sms and calls without problems. My connection has 3 bars but with a "!".
Things I've tried:
-Flashing a 4.4 rom(still no data)
-Flashing 3 other android L roms
-Flashing another radio
-Changed data to 2g/3g/lte
-Checking APN settings
-Changing carrier in the settings
Please help me!
Would be much appreciated
Edit:
I've now tried using the OnePlus One Recovery Tool v1.0 (64gb ONLY) from xda
Now i have "E" yay -.-
Edit(after waiting a bit and rebooting):
H+ Finally i have data again...
Does anyone have an idea how i can make it work in android L too?

[Resolved] [Q] HTC CM7 Radio

Hello everyone, I'm new to xda but not new to rooting and stuff
However I need help
I rooted my Wildfire a while ago..and then i installed some font...which messed my stock rom
receving no technical support over email or service centre, i manually flashed cm7
...
all goinig well but there is no 3g connection at all...the phone keeps on rebooting when i turn on 3g....and 2g is incredibly slow!!!!!!!!!!
I hvnt s off 'ed my wf but hv rooted it successfully..I'd like to know if s off is needed for radio flash...pl help me
How should I s-off my rooted wf??
Hello, i solved this issue.. I was on the radio 3.35.20.10 which is the newest. I flashed the latest rc1 cm7.2. Yes (3g and H) mobile network works flawlessly.. changing a few type of internet build prop values of cm7.2 will lead to rebooting when turning on mobile data
I won't be of any help but I have the same problem: I can't remember when I have noticed it the first time - my Wildfire keeps on rebooting if I switch to 3G.
Initially I thought that one of the different modes (2g/3g only, 2g or 3g etc.) would cause the problem but I have tried everything without any success.
If I find the time I'll probably try a newer nightly to see if this will help.
AFAIK I'm on the newest radio (flashed it a while back due to the well known radio problem).
Anyone with a helpful hint?

Hm, I'm not sure about your solution - could you be a bit more specific? I've already done a lot of things to get rid of the problem - including flashing newer versions of CM7 - currently I'm on the 20120420 nightly. Release date for the newest RC1 is 20120314 if I'm correct - so it looks that this didn't solve my problem.
Furthermore I flashed the radio again (inspired by this thread) - without any help regarding the bootloops. I'm really close to do an RUU update - but I usually rely on good old traditional computer wisdom: "never change a running system" XD
If someone with a bit more understanding of the changes in build.prop could give hints what (which values) exactly could be the reason for the problem this would be really helpful.

Phone stays in Roaming mode.

I've Installed this yesterday, but I'm experiencing a couple of bugs.
I first did a format (disk + dalvic),
then flashed Codename Android v3.3.2
then Camera + Backlit Fix
and then Codename Android GAPPS
Because I have a S-on device, I flashbooted the boot.img from the CA Gapps zip. (other zips didn't have that file)
Everything works very smoothly, but the errors/bugs I encounter are:
4. When I insert my SIM-card, I'm always Roaming, untill I enable WIFI, then I can make phonecalls.
So when WIFI signal is lost, I'm at Roaming and mobile-internet doesn't work.
Does other people have these issues, or is it because of a wrong Boot.img I flashed?

Since I don't want to post this in the dev section anymore, I'll continue here.
This problem first started with Codename Android.
When I install an other ROM; for example Blindbean, the problem stays.
Then I tried MIUI from Shrome, same problem.
(always with format disk and clean dalvik cache)
This night I installed the ICE-DS v4.4 ROM, and everything works fine again.
But when I install Blindbean again, problem is back.
You guys have any idea how this is possible.
Boot.img isn't suppose to be in gapps. Should be inside the rom itself.
When flashing a new rom always do a full wipe.

Ok, so I did again couple of hours of googling and stuff, and found some interesting stuff.
In our country, we have 3 mobile networks with their own towers. (proximus, mobistar, base)
But 2 of them rent these towers to other carriers. (mobistar for example to Telenet)
It appears Jellybean (I have it on every JB rom) sees a difference between the carrier and the tower-network. (If you get my point)
So I have to enable Roaming to be able to use my carriers network.
So far I can see, no additional costs.
But this still is a strange bug, that started with JB.

[Q] Flashed CM11 on sprint S5 and lost wireless network/data

Hi,
I am rooted using the TWRP kltespr version. I flashed CM11 4-07 nightly and at first lost the ability to make calls but still had LTE data (go online, get email). After a reboot I lost both completely. Can't make calls and can't get data. I have done a complete wipe and clean installs of a few nightly versions. They all install without errors but I still can't get connected to my network. I have done several factory resets. Under mobile network data is enabled, I have tried "prefered network type" set to LTE, Global and 3G. Still no network.
Any help/suggestions getting my network connection back will be appreciated,
thank you
Search for how to fix your APN. I would say to upgrade your version too, the latest build from October does not have this problem anymore I believe.
Just about every AOSP rom is bssed on CM 11 now if your using offical CM 11 rom. I have flased several official. yhey yo spell out KLTESPR. but I chsnged the updater script no problem

Nexus 5 Unable to make use of Lollipop?

Hey guys, I'm having some crazy issues with my nexus 5..
So I'm not new to flashing, how to properly flash/ect, but no I do not know how to logcat When all else fails i fully wipeout the phone and flash factory and then reflash to whatever rom.
Anyways this is the issue:
When installing any lollipop roms save for pure white lollipop rom (I think it was pure white..something like that...) I can send texts for about 2 hours but then I'm unable to send/recieve any more texts for the duration that I have the rom on my phone. I mean ANY lollipop rom.
So it must be a radio problem right?
Tried flashing the radio I know works KTU84Q (4.4.4 Release 2) / KTU84 P.
Clean flash w/radio = NO SIM
Dirty flash w/radio = NO SIM
----------------------------------------------------------------------------------------------------------------
Wipe phone and install ANY KitKat rom:
Everything works perfectly.
Anyone have any ideas? I'd like to really use lollipop because that's where all the development is heading..but it just seems that if I do use it..I won't be able to text or do anything aside from hangouts wifi :/
*EDIT* I've double/triple/quadruple checked my apn settings are correct.
Carrier: T-Mobile.
Does it work on stock L images?

[Q] help plz. Data conection issues

Hello world
I have a 64gb oneplus One. I'll make it simple.
With CM 11S everything works perfectly
With oxygen OS everything works.
With cm 12s or any cyanogenmod based 12 por 12.1 i have connection problems. When i disconnect from a WiFi network, the OPO cant reconnect to data. It just shows an exclamation mark on the signal indicators.
The only way to make it work is to enable/disable airplane mode.
Ive tried every apn configuration from my provider.
Ive tried several módems
What else can i do? Its not a hardware issue because it works perfectly with the avobe mentioned.
Its annoying because i keep missing whatsapp msgs or stuff like that
Thanks un advance!
When switching between ROMs, did you always flashed the correct hardware for the given ROM?
Now i have cyanogen OS 12s. I flashed 11S vía fastboot and got all the OTAS
