No 3G after flashing, only EDGE

Hi !!
Looking in the forums, i have seen this problem in other models
The solution, normally, is to reset the APN settings to default (haven't worked for me)
flashed to stock firmware ... still with EDGE
Someone have experienced the same problem ?

Try a factory reset

u flashed back to stockrom using odin?
i have no idea bout this problem
but if you flashed stockrom using odin and did hard reset should fix the problem.
make sure its not about a network trouble from the provider

you might try this...open setting>wireless and network>mobile network. untick use packet data. network mode, choose wcdma only. tick use packet data.

This is what i've done
1- Flashed to an Indian firmware version, no backup (my mistake). From that
moment, losed 3G/H connectivity
2- Flashed various firmwares, no success
3- Thanks to Doky, i was able to get the original firmware of my phone, installed it and change the country via *#272*_your_imei_# and reboot
4- Still with EDGE ....
In a previous flash, i used the "WCDMA Only", but i lost my mobile network .
Going to test in another phone to see if it's a provider problem .....
Thanks for your help ...

when i used "WCDMA Only", my current network changed (i'm from Colombia, my SIM is movistar, changing the setting changed the current network to Tigo) ....

based on your explanation, it seems that you have bad signal reception dude...

There's something special with that version ? ... i'm trying to not flash my phone unless the firmware has any sort of light to solve my problem (avoiding factory reset ... my phone must be dizzy ... so many resets ... )

Try another sim card.

[Q] Regarding APN on cm9

Hi,
There are multiple apn's provided by my service provider,I'm using 2g data plan but somehow my service provider lets me in 3g network.
Now when i use a perticular apn on cm9 or any rom based on cm9,i get speeds around 384kbps,but when I use the same apn and setting with any gb rom or even froyo rom,it just doesn't work.Only the stock browser works.
I want to know if there's any tweak included in cm9 that lets it happen ?
Any ideas folks ?

Make sure "Use only 2G networks" is unchecked under "Mobile network settings".

Did you try to restoring the defaults via the menu ?
You can use APN Backup & Restore to clear all APNs,after that try to restore the defaults.

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

I had similar problem.
I'm on E975 and I was able to get networks connecting manually because LTE is on by default (but it was always droping)
After changing to 3G no more problems. Have you tried this?
P.S. I never tried to solve the 4G issue but probably I need to change APN settings.

Mine doesn't even recognize the network. Can't even search for it manually. I reflashed the KDZ and flashed the baseband still no network :\

Don't understand what you mean... after reboot you get any message? What do you have in status bar? the red cross over the signal icon?
That what I was getting...
You can't go to setting - more - mobile networks - network operators and seach networks? Why, it's grey?

Yeah I;m getting the red cross. When I was in CM 11, I tried searching for networks manually but it would just be a loop. So I reflashed the LGF180S KDZ and I am back to stock. Still I have the red cross and the stock rom does not allow to search for networks manually.

I'm with E975 stock ROM and I have the options to search network, as I mention above and you should have too.
The problem here could be that it's grey and you are not allowed to do it, but the option is there, is that your case?
I'm not sure if I had that before (you know so many flashes...) but I've always solved my issues by restoring to a previous works ROM. I remember that I got GPS issues too and I restore a ROM backup.
I believe that I can't help more

first if you read a little and ask in the Vanir rom thread if you can't see which of the 2 roms are for your phone, you need to have the correct modem flashed to the rom aswell, plus using the right APN's or else you can have network trouble.
i am running stock CM11 on my own E975 and it don't have any mobile network when i do a reboot or a cold boot, but then i go in and search for network and all networks in my country shows up, and i just choose the one i want and i get 3g/4g LTE no problem there
