Wow. OK, there are 2 ideas that may help...
The one that should help a lot is to flash a base-band from this thread http://forum.xda-developers.com/showthread.php?t=1688049
The baseband suggested by CM10 teams is "72", but I know from experience that "77" works perfectly well.
After you flash the baseband (using flashtool), you need to flash the libs that go with it (using CWM).
The other idea is to go to "Settings", then the "More..." option just below "Data Usage", then "Mobile networks", then tick "Use only 2G networks".
This is the same as your earlier work-around, so it may or may not work.
Good luck

thank you for your replay , i just flashed the 77 baseband and and the lib file , but still have the same probleme and when i choose 2g only the phone reboot again
should i maybe clear cache after flashing ?
edit even after clear cache and data the problem persist

Ok, then there's one last idea that might help.
http://forum.xda-developers.com/showthread.php?t=1836071
There's a stock rom at the above thread that could maybe get your phone back to the way it was...
Otherwise you can search for threads that have images of stock roms.
Oh yes, one other thing.. if you are running pdroid, then be careful how you set it up. (I've made some weird mistakes trying my luck with permissions)
I hope you are not stuck with only SMS and whatsapp..

simple: make full wipe and install stock kernel with shipped rom. If your phone reboot again, then it's hardware problem

[Q] 3G mobile data is not working

I've flashed Xperia Z Jelly Bean v4 (this one http://forum.xda-developers.com/showthread.php?t=2267230&highlight=data) on my Arc S and I can say its so fast and so beautiful.
The only problem I have is that I cant connect to mobile data 3G however my APN settings are correct
I flashed BB-77 too as recommended by one of the users in the thread and it didnt work as well
So what should I do now ?
Thanks

Were you able to use the 3G connection before this ROM?
My current advice - Ask from your operator, if the 3G connection is enabled for you.

Are you sure you have "Data enabled"? Try to reboot your phone.

Yes I was able to use 3G before this ROM and i contacted my operator and 3G is enabled already
Does that have anything to do with the baseband ??

Well, if in the thread you downloaded it from was nothing more to flash, then nop.
I said it because in GB Roms you must flash an additional libraries, but i dont had used CM10 based ROMs so i can just can guess, check the baseband threads.
By the way, sometimes my phone "losses" the data connection for a while (the icon dessapear even if the data connection is active). It just happen like 2 times since a got it, but after some time it comes back.

Flash latest stock 4.0.4 and then install Xperia Z Jelly Bean v4.

Well, in the thread I flashed something called Xperia Arc S 4.1.B.1.13 Vodafone DE firmware and they said it's for increasing system and data memory for Arc user and latest BB. You think this is the problem ?!

the phone is not set to gsm only?
look at settings - more - mobile network - uncheck 2g
also look at the accesspoin and choose the right one

Guys please this is really urgent and I did everything I could
Last thing i did was flashing every stock thing on the phone, stock GB, stock kernel, stock baseband and nothing changed and data mobile is still not working

You can try to input the apn by yourself

And finally you have paranoidandroid or back again in the previous rom? With a little search in the forum i found this "Hey...I found out why I didn't have service and was able to fix it. When I had flashed AOKP, there is a setting in the Mobile Networks screen to change the CDMA subscription to RUIM/SIM. Somehow (probably playing around) I changed it from the NV to RUIM/SIM. THEN, I nandroided back to stock, and had no service. As far as I know, that CDMA Subscription option isn't on the STOCK ROM...so I was baffled. Good thing I remembered what I did."
Try it and report..!

i'd recommend that you flashed again your previous rom to see if it is rom related or not. I ve read somewhere that some people had problems with the signal when flashing aokp.

i going to take it to the samsung cc....... lets see what they will say about this problem

I am suffering a very similar and strange problem. I have a Dmc3 deodexed and rooted Rom with NEDLK1 baseband (3 ITA operator) since 3 months. I have done nothing special (no new apps nor flashes) in the latest weeeks. I have never flashed any other ROM. But 2 days ago I saw NO service. I have correct imei, could even surf the web but no telephone functions. Rebooting the phone did not work.
I thought of a SIM card issue and yesterday I asked my operator for a new sim. While I was waiting the new sim to be enabled, today I pushed in my Note 2 another SIM by another operator. After some hours I had the same trouble with this SIM.
So the problem is the Telephon. I don't know if hw or sw, but there is an issue.
Now to see what may be, first I changed the baseband Modem and flashed a stock XXDLK7 and inserted the new Sim inside. Now I will wait and see.
In case of continuing issue, I will try and go back to full stock operations.

Hello guys. I had the same problem, and it was a hardware problem. The solution is really simple: put onto the left of the camera, inside the chassis, a small piece of papero of 3 mm. It's enough to strenght the connections of the flat of the SIM card connectors to the motherboard

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

Sent from my LG-E975 powering Stock 4.1.2

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

Network Signal Dropping after update to 6.0M (Poland)

When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:

Same issue. I am on stock 4.4 and mobile network signal keeps dropping on weak signal area. I set to gsm/edge mode to mobile network. But nothing goes fine.

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...

Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
