[Completed] please help....No signal In GSM/2G Mode, But 3G/HSPA working fine - XDA Assist

I was browsing the net and suddenly the mobile freeze and i had to reboot it.
Then there was no signal and then i changed to WCDMA(or 3G ) mode and it worked fine.
This problem is with both the SIMS( one airtel sim & other idea) suddenly. I can use 3G but cannot 2g.
When I manually search The network operator in the GSM/2g only mode by settings>more>mobile networks> network operators>manually then I can see that the 2g network of both the operators is available and when i click on that network then it just shows " Registering on network...." for 2 minutes and then it says "can't connect to this network right now, try again later" ,both the times I search the network manually for each Sim.
I have flashed stock Rom twice and had factory reset, but the problem still persists.
Please help

[Completed] [Q] Flashed CM12 To Galaxy S5(SM-G900F) and now I have no cell service

Hey everyone. I recently flashed the new CM12 rom to my Galaxy S5 and mostly everything works fine. The only problem I have is I can't make calls and/or send text messages. My carrier is Sprint and my model was formerly SM-G900P however after I flashed CM12 it now says SM-G900F. Whenever I click on mobile plan it says "Sprint has no known provisioning website". I can't even access the APN settings. Can someone please help me fix this, I love CM12 and would rather not go back to stock. I have no problems with my IMEI/MEID number, and under Status in settings my phone number still comes up however for Network it says "Searching for Service" and for Mobile Network Type it says "Unknown", it also says "Disconnected" for Mobile Network state. Is their any way to fix this?
Hi
Thanks for writing to us at XDA Assist. From what I can see you have the Sprint S5 (CDMA) but it looks as though you've flashed a ROM for the GSM model. GSM and CDMA are totally different mobile technologies so using a GSM ROM on a CDMA device will result in exactly what's happened to you. Where did you find the ROM that you flashed? Can you provide a link please?
Your device forum is here:
Sprint Samsung Galaxy S 5
Make sure you bookmark that page. Make sure you only ever use ROMs/kernels/mods/modems etc from within that specific device forum for your device. There are many different variants of the S5 and you can't mix and match ROMs, this time you probably got lucky but flashing the wrong firmware can very easily brick your device.

[Completed] Cyanogenmod 12 for HTC Daul Sim (Network issue)

Hello
I recently flashed CM12 nightly offical rom
I am liking it very much but i m have trouble with the network settings
Dual Sim
Sim 1 - 3G Data Only
Sim 2 - Calls only
Now when i set LTE network mode on sim 1 and do the *#*#4636#*#* i get the H+ working but the sim 2 setting switches to 2G which causes calls to loose all incoming/Outgoing audio...
and when i set LTE on sim 2 calls work fine but then sim 1 switches to 2G causing low speed untill i manually change that back...
I have searched lots of thread but found no working fix for it for my HTC 816 daul sim
Kindly guide me to the thread where i can get my problem fixed permanently..
Thanks
Hello, thank you for using XDA Assist.
