Hey there guys, I apologize if this has been covered, as I feel its related to an "efs" folder type of issue. I'm just not quite sure where the hell to even begin searching.
I've been on 4.3 since the leak and have been using Cataclysm 4.3 JWR ROM for a while now, problem free. All was running great until yesterday I was downloading some media and transferring it to my laptop (~10gb of traffic before I noticed the problem), and my WiFi shut off and restarted itself. My mobile data kicked in at that point for all of 10 seconds until the WiFi reconnected and within 30 minutes my signal bars suddenly dropped to zero and calls couldn't be made. "Mobile network not available." message appears. So I figured i'd pull the SIM, replace and reboot. When that didn't work I tried rebooting without the SIM, to see if it would detect no SIM card and prompt me to put one in and reboot to be able to connect to mobile network. Well nothing was detected. A full wipe, reflash of identical ROM, reflash of updated ROM, reflash of original JWR deodexed & rooted backup, all with the same outcome. I have tried everything short of downloading the stock image and flashing that but I haven't got around to it since I haven't had time to backup my internal SD before losing all data. I should note that I'm on baseband .84/4.3 bootloader and have been since Google pushed JWR & JSS. I haven't tried flashing a new modem, I figured that wouldn't been an issue. I suppose I'll try flashing .48 and update.
Edit: I forgot to mention that yes, WiFi is in fact working. Mobile signal seems to be the only thing affected.
Edit: Reflashing baseband .84 and .48 didn't work.
I really appreciate any ideas guys, I'd like to sort this out rather than having to flash stock and RMA it or something :/
All settled, it was an issue with the frequency band my provided operates on. Mod can lock/delete thread thanks.

Hello,
I have a strange problem with my SM-G900F. After a couple of Mobile Odin Pro flash fails and restoring the original firmware with desktop Odin, I now have a strange problem: everything works ok on 2G/3G/H/H+ but when I switch to 4G I have only data and no signal bars. I tested data connection and it works ok but, of course, when I try to make a call it says "no service". If I switch back to 3G, everything works on again.
I tried factory reset, wipe cache (from recovery), nothing seems to work.
Any ideea how to fix this?
Thank's

Hi guys.
From 2 days am facing a problem on my nexus s that's the mobile network signal is not available.
When i restart my nexus s after some minutes later the mobile signal comes up and some moment later the signal goes back offline.
My sim is working great on other device.
This device was running on Aosp 4.4.3 kitkat rom.
I tried some following steps to fix this problem :
1. Unplugged the battery, sim card and restart,
2. Wiped cache & dalvik cache (didn't fixed),
3. Flashed the factory image from google (Didn't fixed)
Can anyone please help me to fix this problem?
Thanks.
Update :
Well finally i figure out what is the problem.
Actually It's my sim which was causing the problem.
I've to replace my sim card.
The sim card lost network signal after some min.
Last night my phone started acting up on the recently flashed official CM13 nightly 25-3. So I tried to restore my nandroid backup of the CM12.1 version but got stuck in a bootloop. I manually reflashed CM13 but can't get internet through wifi or cellular data, wifi is off and keeps displaying "Turning on wifi" with a grayed out toggle in the on position, Data is on but there is no H or LTE displayed next to my signal. Calling and texting work fine though.
I tried going back to stock Cyanogen OS with the windows toolkit but still the same issue. Installed Chroma kernel and flashed the Marshmellow firmware but still no fix.
Anyone have any ideas how to resolve this?
Edit: Data works now, it was an APN issue. Still no wifi though. And apparently Bluetooth isn't working either
Hi, my device is in a trouble with its signal. It sometimes lost (no service) that never happen before the device fall. I am not sure it is a hardware or a software problem. It is because if the signal lost then I reboot to recovery sometime it is back (In service). After reinstall MIUI ROM, it also back although lost again and reboot to recovery did not work also. So I install custom ROM (RR 5.8.3) but Initially the signal still lost (no service) but a few days ago, it start to back (In service) again.
I read in some thread in MIUI Forum that it is need to reinstall modem. But I don't sure it suitable with my problem. And is it modem for MIUI is suitable for RR OS?
Can you give me some advice?
Try wipe cache partition via twrp. Turn off your device, then press power and volume +/- together for entering twrp. It could be helped, but it could not.
I have the same problem on signal strength when using RR 5.8.4. But I'm sure that it could be problem from signal quality on my home. It's not happened when using MIUI 8. But, when comparing with other device, Samsung J7 (upgrade to Nougat 7.0), it looks like the same problem on the same operator that have weak signal on my home. I ever have editing build.prop for increase signal strength, but nothing increase signal strength.
may it caused by you drop the phone, and then the antenna cable be unpluged
Open the phone and check it
