FYI I am on mdk with hyperdrive rls15 and have same problem. My csc.apk is in system/apps. I googled delete csc.apk and came up with " CSC.apk -- NO. This breaks CSC. According to insanity, this can be removed after first successful boot, but if you ever have to hard reset or restore factory settings, this will not allow you to boot successfully." Does this become just another thing to try to remember under those circumstances?

Also, Go seems to get around this and send mms. So go figure. That was with csc.apk moved to card but not rebooted.

---------- Post added at 01:40 PM ---------- Previous post was at 01:30 PM ----------

Rebooted and base sms will not send mms and just sits in sending mode so returned csc.apk.

I'm running Hyperdrive RLS13 (non safestrap) and previously using modem I545VRUAMDK. I flashed "I545VRUFNC5_modemzip" from the modem only section. My speeds and connection in general have improved but I have lost all audio (music players, phones calls, alarms, etc.). I know the guys on CM have had problems but haven't seen anyone running Hyperdrive having audio problems. I'm assuming I could flash back to an older modem and that might fix the problem but these new speeds are nice. Any ideas?
[Verizon Samsung Galaxy S 4] jorceshaman:
Try flashing MDK + NON-HLOS. If that fixes your issue, try the NC5 Modem only again. If you're still having issues, flash back to your MDK + NON-HLOS and try the MK2 Modem only.
[Verizon Samsung Galaxy S 4] Saear:
Success, "flashing MDK + NON-HLOS. If that fixes your issue, try the NC5 Modem only again." restored audio and maintains the NC5 modem. Thank you for your help.
[Verizon Samsung Galaxy S 4] myklbear:
Is there a simple list somewhere that gives any benefit to each modem? What non hlos does. And what is different in dev versions.
[Verizon Samsung Galaxy S 4] jorceshaman:
Dev versions just come from the dev devices. MK2 and up have AWS, and beyond that every newer version is supposed to be slightly improved. Everyone has a different preference and different experience. Try them out.
[Verizon Samsung Galaxy S 4] Bait-Fish:
And, like Surge1223 stated in the OP, the non hlos should match the version your bootloader is. Basically, you don't need to flash the non hlos.

An example. My Dev Edition bootloader is MDK. I can flash any of the modem only files no problem. I have no reason or need to flash any non hlos since I am not flashing the bootloader off MDK.
[Verizon Samsung Galaxy S 4] swieder711:
Here is what I can tell you anecdotally:

With the MK2 modem the phone seems solid

With the NC5 modem, when in a weak signal area I was only getting a 3G signal. If I toggled airplane mode the phone would sometimes pick up an LTE signal, but usually went back to 3G until I was in a area with a stronger cellular signal

With the NC2 I had a dropped voice call in an area with a moderate signal.

I have an app called "Network Signal Info Pro" that reports Network Strength and all sorts of other data. Let me know if there is any info that might help figure out what is going on.

[Verizon Samsung Galaxy S 4] cnorman76:
Hi guys, I'm back again. I don't know what happened. A few weeks back I flash the wrong modem to my phone any couldn't make or receive calls. You guys helped me get the right one back on. Well, something else has happened. I swear I haven't downloaded or changed a thing. Phone worked great until about 5pm today. I tried to make a call and all looked correct. The call would connect but no sound on either end. I checked my bootloader and I'm on MDK. I flashed the modem again and even redownloaded a 2nd and 3rd time. When I flash sometimes I get a working phone for about 5 minutes than I lose it again. Any thoughts?

Which ROM are you on? I had the same issue on the 5/4 build of CM11. I dirty flashed 5/4 overtop again and have been fine since. Not sure what the cause was but the issue hasn't returned (have since updated to 5/18).
[Verizon Samsung Galaxy S 4] cnorman76:
I'm on Hyper drive rls 15. I've tried complete wipe and install of same rom and even different rom. I know my microphone works because I tested by sending text by s-voice. Sorry, I should have mentioned all this the first time.

No worries. I didn't wipe anything, just flashed the same ROM over top.

Off the top of my head, no. Sorry.

When I get in this situation I usually wind up going back to stock and starting over. Such a PITA when I have to go that route. Hope you get it figured out.
[Verizon Samsung Galaxy S 4] moparfreak426:
I was on mj7 for a while, updated to nc5, had awesome data speeds, then it stopped all data connection, tried wiping cache etc. Toggling, rebooting... Nothing brought it back, flashed nc2 to no avail. Went to mk2, worked for a couple days then back to none again.... So back to mj7.....nothing. Any input here?
[Verizon Samsung Galaxy S 4] jorceshaman:
What's your baseband? Flash the HLOS of your baseband and see if that works.
[Verizon Samsung Galaxy S 4] moparfreak426:
I'm on old mdk bootloader so I can flash me some aosp roms
[Verizon Samsung Galaxy S 4] jorceshaman:
Have you tried flashing the MDK + HLOS to see if you get your connections fixed?
[Verizon Samsung Galaxy S 4] moparfreak426:
No I haven't. I've been flashing modem only..... But I was so impressed by nc5 modem data speeds.... I'd love to get that working
[Verizon Samsung Galaxy S 4] jorceshaman:
Try that, see if your issues are resolved. If so, try the NC5 modem only again.
[Verizon Samsung Galaxy S 4] moparfreak426:
Well I have lte but shoot is it Soooooooo slow.
[Verizon Samsung Galaxy S 4] fireattack7:
I'm late to the party, sorry.

I assume these modems are flashable in the recovery?

I'm running the MDK bootloader currently with the ME7 radio (flashed via Odin). Will going to the latest modem cause me any issues? I am running Carbon ROM nightlies (4.4.2).
[Verizon Samsung Galaxy S 4] Mistertac:
No shouldn't cause you any issues

Grab a modem only file and flash in recovery. I'm on nc5 and works great
[Verizon Samsung Galaxy S 4] fireattack7:
I went ahead and flashed NC5. I get roughly the same speeds I had with the ME7 radio. I guess the latest Verizon signal hasn't hit my area yet.
[Verizon Samsung Galaxy S 4] vt0r:
Definitely sounds like your region hasn't gotten the AWS upgrade yet.

If you don't see any signal or quality degradation with the new modem, you might as well stick it out until the day when you suddenly get 50+ Mbit/sec speeds (AWS has risen).
[Verizon Samsung Galaxy S 4] jmac112:
Hi Everyone!

I’m new to the rooting community and hoping to get some help with my new used phone that I bought off swappa. Here’s info on the phone:

Rooted Verizon S4, has Loki'd bootloader, currently running CyanogenMod 10.2-20131014-SKANK-jfltevzw, Android version 4.3.1.

I’ve been having problems with the 4G LTE signal / speed. I will get 1-2 to 0 bars and then drop to 1 bar of 3G when I pull it out of my pocket.

After reading around online, I think I might have an old signal band on the phone. How do I find out what modem is on my phone?

Will installing a new modem fix the problem?

I really appreciate any help and guidance you can give me.

Thanks!
[Verizon Samsung Galaxy S 4] FernBch:
Go to settings>about phone and look for the baseband info.
[Verizon Samsung Galaxy S 4] jmac112:
I'm on I545VRUAMDK. What baseband is the newest one? I545VRUFNC5?
[Verizon Samsung Galaxy S 4] gordo2212:
Yes. Only flash modem.

[Verizon Samsung Galaxy S 4] nmerc001:
I just flashed the I545VRUFNC5_modem file to my phone without wiping anything and seen a huge bump in speed coming from the ME7 modem. I am currently on Cyanogenmod 11.0 M6 and where I tested the net speeds, was averaging 1-2mbps before flashing the newest modem to averaging to 13-15mbps! As of right now, no issues.
[Verizon Samsung Galaxy S 4] 318sugarhill:
I wish I got good results with the newer modems but i hate them all. If I get any kind of low 4g signal...it drops to 3g. At work..at home...never had this prior to kit kat. I'm back to the MDK hlos. Huge improvement at work keeping 4g and it did wonders for battery life as well...since the better the signal, the better the battery life.

My question is which radio was the first for the AWS spectrum? I know one of the radios be for kit kat had it. MK2 works ok for me...but i feel it was better prior to lot kat. I feel like MJ7 was first with AWS
[Verizon Samsung Galaxy S 4] vt0r:
We've definitely seen mixed results in this thread about the newest modems, so just use the one that works best for your area.

The first modem to have AWS (that was released to everyone) was MJ7, so you might as well try that out to see if it's stable enough for you.

bluetooth

I am having issues on hyperdrive 16.1 and bluetooth. It simply will not turn on. I have tried everything from clean flash to dirty Flash, to going back to mdk modem back nc5 modem. Nothing is working. What's strange is only a few users are reporting the same issue. I am on mdk boot loader. Any suggestions?
[Verizon Samsung Galaxy S 4] shpotik:
I'm new to this modem stuff! I'm on mdk baseband version. I have attached a screenshot of my about phone. What is the best and safest modem I can flash? Any suggestions? Thanks in advance
[Verizon Samsung Galaxy S 4] Mistertac:
Try any one of the " modem only " ones and see how they work for you.

I'm on NC5 myself.
[Verizon Samsung Galaxy S 4] thejulianath20:
Sorry if asked before, but I can't find it....

Are these Modems the same as the Modules for Safestrap?

When I update my phone to 4.4.2 and then flash Hyperdrive and I would normally do the Modules, would I instead use these Modems? I can't find the Module for NC2 or NC5...
[Verizon Samsung Galaxy S 4] k1mu:
No.

The Modem runs the radio hardware. That's responsible for the signal handling for WiFi, 3G/4G/1x, Bluetooth, etc.

The kernel modules allow the kernel to control the radio hardware. The modules have to match the kernel that you're using, however having a newer modem doesn't stop the kernel hardware drivers from talking to the modem hardware.

So, they're independent. However, having an up-to-date modem can enable things (like Band 4 LTE) that you can't get by updating the kernel modules.

I just did ur upgrade prosses on my mk2 phone...

I flashed hyper16.1 then modules then later on NC5 modem...I had twice the speeds on mk2 modem..

Can I just flash my mk2 modem over all this and then reflash my modules????

I am currently on mk2 boot loader with nc5 base and nc5 modem..

Any help would be great....much appreciated
[Verizon Samsung Galaxy S 4] lazer9:
You should just be able to flash the "RETAIL" Mk2 Modem from the (1st section of OP) and not require any other modules or anything.

What's the difference between this modem and the fnc5 posted in May?
[Verizon Samsung Galaxy S 4] Mistertac:
That ones from the Dev S4 that's all. Nothing major
[Verizon Samsung Galaxy S 4] Alxoom33:
Any reasonable to re flash this one?
[Verizon Samsung Galaxy S 4] Mistertac:
Not really to be honest. Going between certain modem builds like MDK to MJ7 or something is worth exploring but I don't think the Dev modems are any different side from there build number changes is all..
[Verizon Samsung Galaxy S 4] swieder711:
Some folks have reported better results when using the NC5 Dev modem versus the retail one. My signal got worse when I moved from the retail MK2 to the retail NC5. I am back on the retail MK2 and was thinking about trying the Dev NC5 modem.

I am on this ROM: [ROM]KOT49H【4.4.2】AOSP Official Google Edition 【Verizon!】05-30-2014

Thoughts?
[Verizon Samsung Galaxy S 4] Mistertac:
I'm sure that's true. Modems are a hard thing to recommend since from what I've seen on here it differs so much based on the users location.

For the longest time I was on the Mk2 one myself but recently Nc5 has worked out great for me. Just have to test and see what works
[Verizon Samsung Galaxy S 4] Surge1223:
I find this to be true personally for me, but your results may differ. IMHO, the dev NC5 modem was a pleasant surprise.
[Verizon Samsung Galaxy S 4] scrillakev:
So I flashed the GPE ROM last week & noticed I wasn't getting fast LTE speeds while at work (Downtown NYC). I was still on the MDK baseband so naturally I wanted to upgrade to a newer modem to unlock AWS since its available here in NYC. Ran a few speed tests and here's what I got.

On MDK Baseband (Downtown NYC)

On MK2 Baseband (Downtown NYC)

On MK2 Baseband (Hollis NY)

Also had a colleague of mine test out his speeds he's on a MDK modem still running TouchWiz and he also got some pretty crappy speeds. I did have an issue with sending SMS after I flashed MK2 modem. I pulled out the battery and everything seems to be okay so far. Really hope I don't have to keep doing a battery pull to get it working.
[Verizon Samsung Galaxy S 4] crossen0:
The first three are retail NC5. The last three are GPE NC5. Nice little bump for me.
[Verizon Samsung Galaxy S 4] equake:
Nice to see you on this thread. Does it make a difference on which ROM is being run? I'm on Stock Consumer MK2 with the NC5 consumer modem and really see no difference then when I was on MK2 modem.

More personally, which ROM are you running?
[Verizon Samsung Galaxy S 4] eklipz3:
I hope i'm not out of line here but was wondering if the modem has anything to do with accessing service mode? since i updated i can only use a few codes. disregard if this is the wrong place for my question.
[Verizon Samsung Galaxy S 4] ruffryder91290:
I've been running the developer NC5 for a day now and results are great, thanks
[Verizon Samsung Galaxy S 4] scrillakev:
Does anyone notice a delay in receiving or sending SMS?

EDIT: Has it been confirmed that the Dev modems works better with AOSP ROMS rather than retail modems that work better on TouchWiz? Or maybe it just doesn't matter at all.
[Verizon Samsung Galaxy S 4] gordo2212:

I've also been pretty surprised with the dev modems. Seems the dev NC 5 us just as good as the retail on David's aosp rom
[Verizon Samsung Galaxy S 4] scrillakev:
Okay so I've noticed that I'm not getting very good cell signal its staying around 98 - 102 dBm (Running GPE Edition). Decided to flash back to my stock nandroid to see if I'd get the same results and I am. However my brother has an S4 and he's getting 70 dBm.

Should I flash the MDK+ NON-HLOS and see if it resolves my cell issue?
[Verizon Samsung Galaxy S 4] cobra7361:
I would just try flashing the retail modems first..

Try mk2 ..nc2 and nc5....there is also the Dev edition retail modems...

Mk2 works best for me in my area...
[Verizon Samsung Galaxy S 4] scrillakev:
Yeah tried those out, didn't help increasing the cell service. Is there anything wrong about flashing the MDK+ NON-HLOS just to see if it would resolve it?
[Verizon Samsung Galaxy S 4] cobra7361:

[Verizon Samsung Galaxy S 4] gordo2212:
Someone like surge could probably tell you but it really doesn't matter. It depends on your location and device on which modem gives you best results. I always used retail modems until nc5 when I started having weird texting issues. I switched to dev and it was much better.

so, I tried both the retail and dev version of NC5, but I am unable to get connected to 4G anymore. I have a MDK bootloader, so I used just the modem update. I am on a recent nightly build of CM. After flashing NC5, I have lost all the advanced options under "Mobile Networks" - don't have access to things like APN anymore...
[Verizon Samsung Galaxy S 4] cobra7361:
Read all of OP again..

If ur having trouble flash nonhlos of ur boot loader...

Then try a retail modem of ur choice..
[Verizon Samsung Galaxy S 4] the_jaguar:
I flashed with the nonhlos version of MDK and I am still seeing 3G only. I still don't have access to APN settings, etc. I then installed the NC5 retail version now, and I still can't connect to 4G at all. I dialed *228 to activate/reactivate the phone again, but that didn't help either.. I still can't access settings like APN, etc under "Mobile Networks"...
[Verizon Samsung Galaxy S 4] Mistertac:
Dialing *228 royally screw's up your sim card and you won't get 4g anymore.

Call Verizon. Tell them what you did and that can possibly fix it over the phone or you'll have to get another sim.

Has nothing to do with your modem.
[Verizon Samsung Galaxy S 4] scrillakev:
Might need to get a new SIM if you dialed *228 or wait about a week and see if it comes back.

Yikes, I had no idea that I wasn't supposed to call *228.. damn it, I am going to try calling Verizon and see if they can fix it...
[Verizon Samsung Galaxy S 4] Mistertac:
Someone else on here was able to call and they fixed it. Another person mentioned waiting a week and your account would get updated automatically.

Sims are free at Corporate Stores and $15 at retail ones. Good luck!!
[Verizon Samsung Galaxy S 4] FernBch:
That happened to me. I made a comment on having poor service for a while and my kid thought he was helping.

Three phone calls did not fix it. Two of the "techs" told me that *228 didn't hurt anything (they got schooled). Waiting for the phone to update on it's own does nothing. The only way I have ever seen it work was by replacing the SIM card.

And Mistertac is correct. They are free at corporate stores. Takes about 5 minutes and you're good to go.
[Verizon Samsung Galaxy S 4] IMMORTALKING69:
Hi, I'm just trying to understand this completely. I thought the latest modems (nc5) would or should be the best for all gs4s. Doesn't nc5 include all the previous bands and then some? My device, gs4 VZW GPE 4.4.4 mk2 modem KTZ kernel. Tried nc5, worked good but not as good. Does it make sense that the latest should be the best? Did AWS start up on mk2?
[Verizon Samsung Galaxy S 4] the_jaguar:
I called tech support and they checked and said that my SIM is shot. I have to get it replaced. I am going into a Verizon store today to get a replacement SIM. I wonder why Verizon doesn't just block provisioning when they detect it's a 4G phone...
[Verizon Samsung Galaxy S 4] s44:
Yes, it did.

I've found that MK2 beats retail NC5. Dev NC5 is supposed to be better than retail, but I haven't tried yet.
[Verizon Samsung Galaxy S 4] Mistertac:
Well that's great you've got it sorted out.

I'm not sure either why we would be allowed to call *228 if it really did nothing for us other than hose the SIM.

I know these phones are sim unlocked maybe that's got something to do with it.... No idea
[Verizon Samsung Galaxy S 4] IMMORTALKING69:
I'm on Dev mk2! I've tried both retail and Dev of mk2 and nc5 and stuck with Dev mk2! I just want to understand why nc5 doesn't include what mk2 has and then some. I just don't want to miss anything better.
[Verizon Samsung Galaxy S 4] scrillakev:
It really depends on where you're located some people have the best experience on NC5 Dev others have a better experience on MK2 Retail.

Give a few of them a try for at least a week each and see what works best for you. I'm currently on the NC5 Dev going to try the MK2 again though for another month.
[Verizon Samsung Galaxy S 4] the_jaguar:
So I got a new SIM and I now have 4G access again - thanks for all the help everybody!

The one issue I am still facing is that when I go into "Mobile Networks", I have just only 4 menu items "data enabled, data roaming, preferred network type, system select". I don't see any of the APN options. Also, under "preferred network type", I only have the following options: LTE, 3G, 1x, Global. In the past, I used to have a lot more options here. Is there anyway to get them back? or is a factory reset the only option?
[Verizon Samsung Galaxy S 4] Mistertac:
Depends on the ROM you're running. C ROM or Mahdi I believe still have all those options but SlimSaberKat I'm running now doesn't have them... And I can't speak on TW I don't run it.

One of the last Android updates we got seems to have changed up Mobile Networks quite a bit.

What ROM are you on?
[Verizon Samsung Galaxy S 4] lazer9:
Battery life per given modem

Curious as I haven't thought of this until now. Ever since going to KitKat from 4.3, my battery life has tanked quite a bit. Could there be any relation as to the "Modem" and battery life? Has anyone tested or compared?
