No signal or data

I'm not skyraider Zeus preview and have no no issues till last night. Now all of a sudden since last night I have not been able to get 1x, 3g anything and signal drops. Have multiple lines on verizon and the rest of the phones are fine. Really don't want to change roms but will if I have to.

Have you tried to just reload the rom on top of what you have now?
Have you tried to restore a backup?

Okay I just restored a backup of liquid gingersense and same problem... Starting to get a bit scared.

Alright flashed the brand new GB radio from "someplace." Still have same problem. Sometimes I have full bars but no 3g and can't get calls tried to test and calls don't go through so my phone is kinda pointless... I'm really panicking I need this thing...

When you installed the new radio did you also install the LTE radio?

Honestly no clue how would I be able to tell? I've installed nearly every radio and never has two separate radio files.

There are not two separate radios to install. If you downloaded MR3, it will work if you're on a GB Rom. If you're on a froyo Rom then you need a froyo radio.
Also check to make sure your battery door is completely attached. Your antennas are in the door and it must be attached.

Were you running a leaked radio when you had this problem first off?

I was running the OTA MR2 radio since release never had any problems then last night out of nowhere it just happened. Have been scrambling ever since.

Went back to MR2 radio now since I know it's not a radio issue. Battery door is completely sealed. Checked to see if the metal was bent in any way and it's not.
EDIT: Every time I reboot it gains bars back for a bit but no 3g. I've tried calling during this period to no avail. Then it looses bars with just an x over them. The one thing I am thinking is there any possibility that the sim just died...

Did you check your mobile network settings? Are you on LTE only mode possibly?

As goofy as it sounds, when I first rooted my TB awhile back I completely lost signal then was able to pick up 1x and that was it. I did a factory reset on the device (as instructed by VZW), and it actually worked. Nothing else had been done to the device besides a root, no one else could figure out what exactly went wrong, but the wipe restored it back to "factory" root and it worked perfectly.

No LTE/CDMA. I have done like 30 factory resets lol. Called Verizon to make sure there was no outage. I'm getting a new device (Not refurbished shockingly) over-nighted. The big bummer is having to reroot and such, but hey the guy was nice about it and everthing so no complaints. I can live without it for one day. Thanks for all your help guys!

[Q] Got GSIII and reception is terrible

It's easily 50% worse than my last phone (palm pre 3) and I've never had issues at my home with anyone's verizon phone.
I did flash LK1 RPM and Radio from this thread: http://forum.xda-developers.com/showthread.php?t=2007414
I'm not sure if that has any bearing on it and am also not sure if it was like that before. I did it all when I was in town.
Is there another radio I can flash and see if it's better? Or does the GSIII just have garbage reception on the outskirts?
TIA TIA

Diddo on all that..here is a list with all the modems.let me know if you find the best
Good luck

I've tried the miui 4.1
stock JB
and the mean jellybean one I posted above.

To be honest when I first flashed any ROM on to my GS3 my reception was terrible. Every ROM that I used was the same, I also tried every radio available.
My only solution was just to go back to stock which I did now this Stock ICS has me at 4-5 bars everywhere I go.
My last CM ROM had me at 0-1 bar in the same places.
I hope this helps.

Check to see if you have the updated prl version 15154. Do this by going to settings, about phone, status. I think that is an updated list of the towers and that could be your problem. If its not the updated version just shut phone off take out SIM card for 2 min and then just start it up and it should automatically update. I read this somewhere in another post and just figured i'd pass it on. Hope it helps.

Txs mike..I was on something like 14015::' 1 month of fiddling of different modems and radios

Unfortunately I'm already on this PRL
Going to try some ICS roms I guess.

I have tried each radio as they have come out with mixed reviews. Some are better than others for me but YMMV. I have found the latest VRLK1 is what works best for me. I came from the Thunderbolt, and I really miss the reception I had with that phone; however, that is the ONLY thing I miss about it. I am currently running CleanRom v5.0 and VRLK1. I definitely get the best reception, and can maintain 4G at work while the other radios would drop to 3g or 1x. I only hope it continues to improve, but I don't think it will ever be as good as I had with the Thunderbolt. Good Luck.

Did you try all the radios, even the ICS ones.

Mark as solved!
I tried every radio I agree the newest seemed to work best but still was ridiculous. Barely any service even though I had two bars at times. Not enough for a single call and had to be by a window to get spotty text service.
Traded for a lumia 822. Works perfect.

This is funny. Coming from the nexus this phone has way more signal and better reception. Instant switching from 3g to 4g and to wifi. Ive tried every radio and they all work very well. Tried on my nexus and all were horrible. Just my .02 cents but this phone rocks.

As others have said try out all of the older radios and use whichever one works best for you. Unfortunately, this phone is not particularly known for having a strong radio (and no software update is ever going to really fix that).
If you are really on a fringe area of service, this might not be the best phone for you. In my experience, Motorola phones have always had the best radios in the industry, and are the most reliable in fringe service areas.

[Q] Reception issues?

Unlike some people I've always had pretty good reception on my S3 where I live near Chicago. I had been running "Jelly Beans Build 4" for several weeks with no problems (using K1 Modem and Stock Kernel). Then last week I updated to the new Beans build, Build 6 and installed the K3 Modem and RPM (running LeanKernel). Ever since doing that, my reception has gone from always around 4 bars to usually hovering around 1-2 (happens both when I'm at home, and at work in the city and has been pretty consistent). I tried going back to the K1 modems and it didn't change anything (ended up trying all the JB modems with no differing results). I've also tried flashing the stock kernel again. No matter what I do, my reception doesn't seem to change and I can't get it back to where it used to be. Is there anything else I can try? I'm about to flash back to another ROM to see if that changes anything. Any ideas would be great though. Thanks guys.

Maybe check to see if your prl version is up to date. Do this by going to settings about phone them status. Should be 15154. If that is good no modems work and previous roms are no success then maybe they are doing work on some towers in your area. That happened to a coworker of mine on sprint and once they were finished everything went back to normal maybe even better but it took about a week of him pulling out his hair. (he is bald now). hope this helps and good luck.

Thanks for the advice; yeah I checked, the PRL is up to date as well. And flashing back to another build didn't make any difference. So I'm beginning to think maybe you're right, maybe they are doing construction or something.

Reception problems on 4.4.1

Ever since I updated to the newest version as well as the new radio and modem, I get worse reception than before in SOME places.
I don't know what to so to improve it...

The old radio works fine. Try this thread:

I don't know.
As with all updates I ever do, I reset my phone to factory (wipe) and I find my radio as well as WiFi better than before.
In my garage I would always get 1 bar or less (switches back to LTE) now I get a steady two bars in the same location.

Why not? Because he'll have to download all the apps and do his settings again? I find that some stuff I don't need anymore after some updates so instead of having software on my taking over functions that the built in stuff works just as good or better. I would format for EVERY Nightly on CyanogenMod at one point, my phone doesn't contain anything that I gotta have and setting up the phone again is part of what makes it fun because i'll see new stuff and changes when going through the setup again. If you just flash over and over and over eventually you'll start getting issues (shouldn't happen but it does).

While I agree it may not be practical, its something I've done on every machine I've ever owned any time an update is done.
I look at it this way, and although it may not be true for android and Linux its what is burned in me:
Anytime you do an uninstall of a windows program, there are always files left behind, registry entries that remain or invalid paths etc that are no longer required. So in essence not a real uninstall of the old stuff.
Over time your system gets sluggish and doing a full format of your PC gets it flying again.
Sure it's a pain to do but it works.
Now again I don't know if the same situation occurs with Linux or Android, but most of my stuff is backed up to my networked hard drive so really the only thing that takes time is setting up my home screen again.
Further, I'll probably end up doing the same thing once the full factory image is posted.
But I don't know, that's just me I guess.

I also did a clean flash.. In some places I get better radio but mostly it's worse.

Reception for me is just the same as before. I haven't really seen any noticeable decrease or increase.

Both radios still drop signal
Sent from **Nexus 5 sucks**

I have noticed that my LTE reception is worse than pre-OTA. And while I agree doing a clean install is great and I don't really mind re-downloaded apps or restoring from TB. The real problem with this phone is that there is no SD card, so I don't want to have to worry about all the stuff on the internal storage. Of course I have my photo's setup to copy to the cloud but stuff that I download here or there isn't and I like having my photos on my storage until necessary to clean up for more storage. In the past I always had the phones memory plust a 32GB card and the card never got wiped when doing clean installs or factory resets.

My signal definitely appears worse. Couldn't this be just appearance though? I thought in the changelog for 4.4.1 it says that they revised how the signal bars scale. If I go to the battery screen, it says that I am running at a higher time without signal, but my battery life isn't affected by it. I wonder if this is just some bug or related to how the signal is being reported, or if this actually reflects what your cell phone is picking up and what it isn't. For example, I have sometimes read my time without signal being reported at 50% or higher, but I am still able to make calls and receive texts, etc. etc. Therefore that leads me to believe this might just be cosmetic?
Does anyone have any real metrics to prove that the signal is actually worse or are you going by how many signal bars your phone has at the time?
I'm not saying anyone is wrong here, I am just trying to get an accurate assessment of the issue. I have noticed the same thing you guys have in that the signal that is being reported is worse than what I used to have, but I am hesitant to blindly flash back to the old radio not knowing exactly what the issue is. If the signal really is that much worse, shouldn't I be getting much worse battery life? Shouldn't my phone be heating up trying to boost power to the antenna? Neither of those cases are true.

I had to flash back to the pre-4.4.1 radio since on Sprint, LTE signal strength was anywhere from 3 to 10 dB worse, after the update.

[Q] Lolipop radio

Hello
With the final version of lolipop I have a lot of lost cell signal in place where I usually can phone without problem.
I think the new baseband 2.0.50.2.21 is horrible for me.
So can I flash the last radio of KitKat with lolipop?
Thanks

I don't see why it won't work, go for it, but at the same time be careful, back up your data, I've flashed radios for different versions of kit Kat on my nexus 5 before, but never from another version of Android.
Let us know how it turns out!

Just flash the Last kitkat radio all is fine. I'll see if the reception is better.

I'm having the same issue. Since I bought a used rooted N5 and who knows what they did to that KitKat build, the OTA update to Lollipop didn't work for me. So I flashed a full stock image of Lollipop LRX21O from Google's servers last night.
I don't recall ever losing signal in my home, but it currently is going from a full signal to complete signal dropout for minutes at a time. Was doing it in another location across the city this morning, so I know it's not a tower issue.
Please let me know if you find a stable radio that works with this build. Thanks!

I'm having the exactly same issue in Chicago with T-Mobile. I'm so annoyed that I cannot make a call or data is either very slow or keeps dropping out. I'm not sure where the problem is from.

Argh, flashed this last night. All seemed well for about 18 hours, then I have had several episodes of signal dropout this afternoon.

I'm actually seeing the opposite from you guys. Ever since I flashed the stock lollipop ROM and new radio, I've seen signal boost in places where it was terrible before. I would get horrible signal in my house. I now get a steady 2 bars, and my LTE hasn't cut out once. I guess its a Your Mileage May Vary type of thing.
I was on stock KitKat 4.4.4 before. I am with T-Mobile if that makes any difference.

Im another one wit signal issue I have horrible dropouts out of network, for about a minute with new lollipop radio
the worst part I don't have custom recovery any more to flash older baseband,
I'm from Europe. Is there any work around in settings or so please let me know.
