At first I thought it was the ROM, but I flashed 4 different roms and still the same problem. Every time someone calls me it drops my signal, all my bars go away and whoever called me cannot hear me. Idk how to fix this :/

4.4 seems to require at least the 4.3 modem baseband, you need to flash it via Odin. Be careful on the version, note the one already installed and chek which one is the normal upgrade. My m919v only worked with it's specific modem.
There's a few topic about this. Can't post link but look for this one: [ONLY FOR MDL BOOTLOADER] How to use 4.3 MK2 Modem and Retain Sound
Okay so I just returned to stock because I couldn't fix the problem .. so now i'm running android 4.2 and my wifi wont connect. Keeps giving me this when I try to turn on Wifi

So my dad trashed his E4GT by dunking it in a river. Then dropped it at work cracking the screen. Gave him my old one. Had a hell of a time getting it programmed to his line, but I got it. eventually had to flash the One-Click Stock (JB) odin to fix an issue where he could not connect to WiFi. After that, flashed Dirty Unicorn, and all was good. Or so we thought (we were in range of an Airave). Seemed he no longer had any reception off of the Airave. After much searching it seemed possibly due to the fact that the phone refused to leave WCDMA mode. Long story short, I fixed the issue by starting back on Stock Rooted (JB), getting fresh PRL and Profile after wiping EVERYTHING i could find, and then flashed back to DU. He was totally fine for two weeks. Now all of a sudden he again has no signal off of the Airave. He is in a bad reception area, but when it is working properly he gets enough to call, text, browse a bit, etc. But when it is acting up like this, he cant do anything at all off of Wifi and/or Airave.
TL;DR
Going from stock rooted JB to JB Dirty Unicorn, would that cause modem issues (being that the stock rooted most likely has a JB modem, and you arent supposed to use JB modems on JB Dirty Unicorn)?

ICS modem for DU..pretty much all aosp ROMs ( ICS to jb )..the latest ICS modem is FL24. Flash that modem or another ICS modem on the phone. Then do the temp boot to upgrade prl and profile.. If you're on stock again you can flash the modem and update the prl and profile.. Then flash DU.. Making the move to DU shouldn't have messed up the modem..if you did the above..

Yes, i know that. But his phone worked fine for 2 weeks so I wasnt sure if that was the culprit. I have some time before I will have an opportunity to *try* to walk him thru flashing an ICS radio himself >.> so I figured Id ask

No I hadn't flashed an ICS modem. Everything you said the first time was correct. I went straight from JB Stock to DU. Spaced out on the modem because I was in a rush to get everything working. And when it actually did work fine for 2 weeks and now stopped, it threw me off.
I am going to see if tomorrow I can walk him thru the One-click to install FL24

No need for a one-click.. Just have him download an ICS modem from rwilcos repo..( zip format ) and then boot to recovery and wipe cache and dalvik cache. Then flash the modem.. Next time you have a moment you can do the temp boot to update prl/profile

The One-click is nice and simple though. The less steps the better, my dad isnt exactly a whiz with current tech. I already have both downloaded on my laptop in case he doesnt have the confidence to do it himself

You the boss.. But there is no way..hooking you're phone to a computer is easier than flashing one zip file from you're phones own recovery.. In my opinion.. Less steps my way , too. If you need any help with flashing a modem from a phone or you're dad does. Just hit me up. I'd be glad to help.. I finally have my dad texting and my mom on a rooted huawei ascend 2..although I did all the heavy lifting for her,she's starting to get it..lol.

Just ran thru installing the ICS modem. No change. Cant update the PRL or Profile on DU of course, though. Updating the PRL and/or Profile necessary for any change to take effect?
Also JFYI, yes I know what it will take to update them, just wondering if having not done that yet is what would be causing there to still be a lack of signal

This is where I'm not sure, everybody says to update..but I have went without,but I did notice my signal bouncing around..... But I'm in a very good signal area.. I would say an update can't hurt...FYI...I get the best signal on gb27.. On touchwiz...of course. There are some good tw Roms out lately..too. You could always go back to stock to see if its the rom/modem..Then work back to cm/aosp or tw... This signal stuff is funny to mess with..what works for one might not for the next.. I can't remember what carrier you have but a signal repeater might be a choice..

Sprint. He has gotten signal where he is before in DU (and that was with a JB modem, no less) for two weeks. It was low signal, but it was signal no less. Our only option is to get the phone working normal, a repeater will not do as he has no signal at his house, at his job, or anywhere within approx 60 miles of where he lives. Normally he has low signal, but atm he has zero. I am currently waiting for his download of a Stock Rooted rom to finish so we can flash that (which I know for sure will give him signal) then flash the ICS radio, update PRL and Profile, and then try DU again. If that does not work I will just have to have him stick to the Stock Rooted JB rom, since we know he gets signal on that.

Sounds like you have a plan..hope it works for ya.. if ya run into any problems don't hesitate to ask..
Hi all, I was flashing a Infamous Google Edition ROM and everything was okay until my phone booted up. My carrier is WIND and I have the SGH-M919V, and every time I locked/unlocked my phone I wouldn't have a signal. I would have to search for my network every time I unlocked my phone, which was really irritating. I tried three other Google Play Edition ROMS, and they all wouldn't let me get a signal. This is strange because I have previously flashed the INFAMOUS S4 ROM with no problems whatsoever. I am currently on Android 4.3 stock rom.
My question to you guys is this: How do I fix the no signal problem so I can get a custom rom again?
Rooted with CF-Auto-Rooter, and used Philz Touch 5 if that helps.
Thanks in advance!

Sigh... What bootloader are you on? KNOX or non-KNOX? If you are on non-KNOX, you need to Odin flash the 4.3 modem that is all over the forums. If you're on KNOX bootloader, check your APN settings. Hope that helps. :good:

Did you find the problem? I'm having a similar issue, but not quite sure where to find this "4.3 modem". I've read references to the mk2 modem but so far it hasn't helped me.
My issues are on Hyperdrove or Darthstalker roms, my network (wind) won't stay connected if I turn the screen off. But on any AOSP rom my network connection is solid.
Also, on this mk2 rom my connection is fine: https://sites.google.com/site/dannyben777/home
I'm just wondering how I can get my WIND network connection to work on the hyperdrive rom =\
This is what I did:
I was trying to get Infamous S4 Google Edition (which is 4.4) when I was on 4.2.2. I tried to install it, but apparently it wouldn't install properly (forget the details). I tried going back to 4.2.2 to try it again, but strangely enough it boot-locked at the SAMSUNG screen. I upgraded to 4.3 and everything worked, so I tried the Infamous ROM again the next day, and it worked
Strangely enough, every time I try to charge my phone when it's powered off it boots back up again, and says something about a kernel (forget, kind of lazy to check).
Hope this kind of helps!
Hi
I was using android 4.4.2 and all was going great with the wifi and signal. I decide to flash M919UVUFNH7 Stock Rom that is 4.4.4.
Then when i power up for the first time i cant turn on the wifi and the signal was a circle.. I was searching a lot and there are a lot of fixes for i9505 and i9500 but for the m919 there isn´t a lot of information. i found this kernel:
http://forum.xda-developers.com/showthread.php?t=2289140
that kernel solved my wifi network but not my signal netwotk... sometimes but only sometimes it gets signal but then if i restart or power of its very dificult to get signal again on.... i tried airplane mode... a lot of times trying to get signal up...
Sorry my english. Please some help, i dont find nothing how to fix it for this model..
Root with chainfire's auto root. Then odin to stock.
If that doesn't work try a custom ROM like cm.

I have root. and when i flashed 4.4.4 y flashed with odin. Stock rom that i said before. but bicuase the probem with wifi and signal i flashed the kernel i mention before...
I would still try to Odin flash again.
It seems like you got a bad flash situation going on.
I'd do a factory reset first.

Thanks For your help! i solved the signal problem flashing the modem in this post
https://www.androidfilehost.com/?fid=23622183712469693
Now i have signal and wifi woriking perfectly. i dont know why some samsung phone on the update get this problems.
http://forum.xda-developers.com/galaxy-s4-tmobile/development/moving-please-post-t3009561
flashed that
Wifi works. Data/Calls do not.
What do I need to update?
Tried another 4.4.4 rom, same result
You probably have to update your bootloader, I had the same problem a while back. I Oden the entire 4.4.4 tmobile firmware and haven't had a problem since.
Sent from my GT-I9505 using XDA Free mobile app
You need to read through the thread and see how other folks fixed the problem. The rom thread that you flashed.

i have the same issue with mahdi 4.4.4 and cm12 latest nighty! i had mahdi for 3-4 days no issue, then last two days no signal! same on cm12

(i read that a simple reset could fix this but never tried)
no signal on first boot, entered apn, restarted
I have 4/5 bars!!!
so how do i make cm12 work??? Idont want touchwiz or kitkat!!!
so i set up the device (accounts, wifi, etc) service staying good.

Well If you really need your phone to work properly, receive and make calls, working mms and have long battery life and not blow up, you may have to settle for stock /touchwiz.

I've got the T-Mobile M919 S4 and I have a 4.4.4 ROM on it (Insane Hybrid).
I've got the latest NK2 Baseband and I also don't want to upgrade to Lollipop since I did before and it was lag lag lag lag lag after a week or so.
I've noticed recently that it is getting very poor reception.
My buddy's S3 will have two bars and mine will show no service. Or it'll have bars but no data service. Or I won't be able to call out.
There also seems to be an unusual amount of spots where I have no service.
When I do have service, the data can get really really slow.
My GPS lock also frequently gets lost during navigation.
Any ideas? Do I need to flash a kernal, modem, or radio or something? Which ones?

Try updating your baseband. That sometimes solves it. Here's the link:

Thanks, I'll give those a shot. I'm going to flash this and see what happens:
http://forum.xda-developers.com/gal...stock-base-4-4-4-nk2-rooted-deodexed-t2990478
I'm still a bit confused on some of the terminology and what's bundled with what.
- The "modem" is the same as the "radio", right? It's a driver that controls how the device deals with cellular voice and data signals. I can find the version of my modem/radio by looking at the last letters in my "baseband."
- The modem/radio driver is usually bundled with a ROM, right? So the ROM that I flashed above will also update/replace my current modem/radio driver?
- Modem/radio drivers can be separate from the ROM itself. If I use a 4.4.4 rom that has NK2 bundled, I can still flash just a NH4 radio using ODIN onto the old ROM and be ok, right?
- Where does the kernal come in? I'm assuming the kernel is bundled with the ROM and the kernal is only in charge of the switching between cellular and WiFi data, right?
That's the price you pay with custom roms, sometimes your lucky and everything works the way it's supposed to sometimes it doesn't.
Run phone for a day and make sure everything works properly after flashing back to stock before attempting custom again.
If you need your device to function as a reliable phone, making and receiving calls and messages you may have to rely on stock roms.
