I would think the better modem would give you better battery life because it doesn't have to keep searching for the best signal. Also I've seen a few articles online where they say KitKat does drain the S4's battery.
[Verizon Samsung Galaxy S 4] Mistertac:
Kit Kat definitely brought some battery draining features... Basically you need to keep everything " Google" in check. WiFi + Location settings as well. I Greenify everything I can and I also don't let Google Play Services keep my phone awake under Privacy Guard
[Verizon Samsung Galaxy S 4] lazer9:
Interesting, but I'm a little confused, Is that a particular app that is allowing you into that section/selections of Google Play Services?
[Verizon Samsung Galaxy S 4] Mistertac:
It's called Privacy Guard and it's built right into a lot of ROMs. I'm currently on SlimSaberKat.... I think there is an xposed module though that may be along the same lines if you can't run AOSP ROMs.
[Verizon Samsung Galaxy S 4] FernBch:
I can't speak for other ROMs as I don't run them.

In CM11 if you want to access the APNs open the voice dialer and say "open APNs".

For the "Preferred Network" menu that changed several builds ago and is what it is now. LTE (recommended) is the same as EVDO/eHRP+CDMA, Global is the same as WCDMA/etc/etc, and so forth. A factory reset will not change the menu.
[Verizon Samsung Galaxy S 4] lazer9:
Yea I looked in Xposed downloads and found one called XPrivacy but it doesn't seem to allow any kind of access to system apps, thus I can't control the play services. :(
[Verizon Samsung Galaxy S 4] Mistertac:
See if you can find App Ops

That may be it

*228 will not fry your sim nemore, Verizon fixed that issue almost 2 years ago, it will put u on a 3 Prl but 4G will work on a 3 pgl your phone will just give off a Lil more heat.... to cycle back to 4G pre just cut your phone off take out sim for 5 min and then reboot, if that doesn't work clean flash any rom and it will update prl back to 4G. .... don't give out bad info without research

---------- Post added at 07:20 PM ---------- Previous post was at 07:19 PM ----------

Or just call Verizon and they can manually push a 4G prl update
[Verizon Samsung Galaxy S 4] Mistertac:
I'm not giving out bad info. Many users have reported that and have also confirmed it on here after talking to Verizon and after flashing many ROMs to try and fix the problem.

I've also done your other methods myself with removing the sim and that didn't work. I flashed many ROMs for over a week while dealing with only 3g and never got it back..

Only getting a new sim worked for me. So before you tell me to do research.... maybe you could do some yourself[emoji3]
[Verizon Samsung Galaxy S 4] FernBch:
I had this happen about 2 months ago. 4G service no longer worked after *228. Power cycling, removing and reinstalling the SIM, factory reset, and talking to 3 people at Verizon did not fix the issue. I had to take the phone to a Verizon store and have a new SIM installed to get 4G working again.
[Verizon Samsung Galaxy S 4] ebsk8er06:
I have had a galaxy nexus g2 and s4 and the galaxy nexus will ghost dial *228 if it doesn't have 4G for awhile and 4G will still work on a 3 Prl, g2 my daughter got my phone and dialed *228 and again on 3 Prl but 4G would still work fine phone would just get very hot when using, haven't tried dialing it on s4 but galaxy nexus and g2...galaxy nexus all I had to do was flash a new rom, g2 waited about 3 weeks it finally updated it self back to 4G prl, Verizon told me the issue was fixed right after micro sims were released...... I've had to replace one sim card and that was when switching from galaxy nexus to g2, g2 to s4 sim took fine
[Verizon Samsung Galaxy S 4] Mistertac:
This is one of those issues where results varied. Some had it come back after some time.... I guess some had it come back after flashing different ROMs. Most of the ones I have read about and dealt with myself either had to call Verizon and they fixed it and/or had to just get a new sim.

There are quite a few of us on here that have dealt with this at one time or anything.

So your right.... Research... [emoji16][emoji106]

radio question

Had posted this to general Q/A but no response so I thought I'd try here as it's radio related:

I am on the 6-25 edition of the GPE rom but for the past several iterations I have been having trouble with maintaining LTE and cell service. I have one of the earlier Galaxy S4s MDK bootloader and baseband.

Basically whenever i go somewhere where there is no or weak cell service the phone has trouble re-establishing it when I go back to an area that has good coverage. I either have to go to access point names and click LTE or reboot the phone. This has long been an issue with GPE rom but it's my understanding that it's mostly fixed now.

Also I should mention that sometimes it even drops cell service entirely (no phone calls) even when I'm in an area with coverage. I usually have to restart the phone at that point.

I'm wondering which of the alternative radios/modems will be the most reliable when entering and leaving areas of low coverage? Also can i just install the zip with TWRP or do I need to use ODIN? Is it safe to flash NC5 modem when I'm on the MDK bootloader? OP seemed to say no but then others had success. Thanks in advance for any help.
[Verizon Samsung Galaxy S 4] scrillakev:
I'm currently on the 5-30 version of Dan's GPE ROM. Like you I'm on the MDK bootloader but I flashed my modem to the NC5 Dev Edition (Please flash MODEM ONLY) via TWRP. I generally get decent cell service 90 dBm. However this weekend I noticed that when I had low cell service at my cousins house I could not send or receive calls. Tried toggling airplane mode on and off but it wouldn't let me re-establish a connection until I rebooted my phone OR powered it off and booted it back completely.

If I don't put my phone into airplane mode while riding the subway I lose the APN setting for 4G and have to reselect it when I'm above ground. I wonder if its the samething when I get a low cell signal if it un-selects the LTE/CDMA/EvDo option.

If anyone has an idea, I'm all ears.
[Verizon Samsung Galaxy S 4] ahaynes42:
Bad hardware?

I've tried a few of these different radios and my cell service seems to be performing decently on all of them. But both my Wifi and Bluetooth signals are consistently very weak. My girlfriend's Moto X will pick up wifi networks that my S4 can't even see. And when it comes to bluetooth, signal starts to break up around 8-10 feet, while most bluetooth products claim a range of 30 feet. Is the radio hardware in the S4 just that bad? Do any other S4 owners here have similar issues with Wifi and Bluetooth? If so, are there certain basebands here that seem to improve wifi and bluetooth?
[Verizon Samsung Galaxy S 4] Surge1223:
I generally don't reply here since I just post the modems, don't really stress test them or anything but I thought I should point out a few things.

1. MDK phones CAN flash any of the modems without having to worry about losing/messing up their loki'd device.

2. Modems generally don't effect WiFi and Bluetooth...those are ROM, kernel, HLOS, and module related.

Enjoy the modems! :sly::thumbup:
[Verizon Samsung Galaxy S 4] Alxoom33:
No, I think there is something wrong eighths rom/kernel that you are running
[Verizon Samsung Galaxy S 4] s44:
Or with the hardware... though if it's MDK you probably won't RMA.
[Verizon Samsung Galaxy S 4] myklbear:
Try another ROM like Hyperdrive.

VZW S4 MDK Hyperdrive 17.1 via XDA Prem.
[Verizon Samsung Galaxy S 4] stromgald2:
Follow up from before:

Tried 3 different radios now (MDK stock, NC5 dev and NC5 retail) and same result on all three. Go to an area of no service (basement tunnel etc) and it never comes back until reboot. Might have to go back to Hyperdive as much as I like GPE for everything else. The one thing I need my phone to be is.. a phone.

Is there anything else I can do instead of restarting? Does the ROM control how often the phone looks for towers? Thanks all.
[Verizon Samsung Galaxy S 4] therobzilla:
I'm on a MDK original phone, I've tried all the modems and testes them all over the west coast of the US, I have had the best success with the MK2 modem out of all the modems.

Just FYI for my phone and I'm on HD 17.1

[Verizon Samsung Galaxy S 4] scrillakev:
Ah man I was hoping this wasn't the case. I'm going to head to my cousins house this weekend where I lost signal before to see if it still does it. This week I did test it out in the subway, did not put the phone in air plane mode while underground and when I was above ground it reconnected.
[Verizon Samsung Galaxy S 4] Mistertac:
I had these similar issues about a month or two ago on AOSP Roms.

The actual modem didn't make a difference, I tried quite a few. Something was updated on CMs side possibly apns possibly something else that ended up fixing the issue and I haven't had the problem again.

Not saying that's the only answer... But I'm just guessing it could be something on the ROM side and how it's actually handling your data hand off.

I don't run TW or GPE though so I can't really say for sure
[Verizon Samsung Galaxy S 4] scrillakev:
Thanks man, I'll just have to hope for the best, really don't want to go back to TW though. ;\
[Verizon Samsung Galaxy S 4] ahaynes42:
Aaah, thanks for clearing that up! I wasn't sure what wifi/bluetooth fell under as far as hardware/software interaction goes. It seems that I need to take this up with CM11 nightly thread. Thanks again for the modems!
[Verizon Samsung Galaxy S 4] cobra7361:
Have u tried wiping ur dalvik and cache after flashing modems?

Or when ur service won't come back on or try turning airplane mode on then

Off?

I always wipe cache and dalvik when I flash new modem
[Verizon Samsung Galaxy S 4] stromgald2:
Yea I tried wiping cache and dalvik a couple times. And have tried airplane mode. Airplane mode sometimes restores it when ive only lost the data signal, as does toggling the access point name. But if ive lost cell phone as well the only thing that fixes it is a restart.

Actually for the past couple days i haven't lost cell signal...maybe it was a problem on verizon's end. Ill keep my fingers crossed..maybe it's fixed.
[Verizon Samsung Galaxy S 4] gleggie:
Which modem is recommended? I'm on the original MDK modem but lately i've been having on and off issues sending SMS, so i'd like to update my modem to see if that fixes it.

Should i just go with the latest modem or is there more to it?

Wifi skype Googkw hangouts issue

So I updated from MK2 to NC5 using Surges method. Im pretty sure that it did not upgrade my bootloader from MK2, even though I'm on the NC5 baseband.

The issue im having is that a can't get audio over wifi using Skype or Hangouts. My audio sound like a chipmunk.

I didn't have this issue before the update.

I read that flashing the modem doesn't do anything for the wifi, that only the Non-HLOS fixes wifi issues.

So I want to flash the Non-HLOS to see if that fixes things.

Should I be flashing the MK2 non-HLOS? Or will I screw this up pretty bad now that I'm on NC5?
[Verizon Samsung Galaxy S 4] Chadwick108:
Download Samsung info from the play store and will tell you the bootloader
[Verizon Samsung Galaxy S 4] hakisac78:
Is not the latest modem out nc5? TIA!!!
[Verizon Samsung Galaxy S 4] ymDroid:
Thanks.

I'm definitely on the MK2 bootloader.

So I'll flash the MK2 non-HLOS to try and fix the wifi audio.

Will this also put my radios back to MK2?
[Verizon Samsung Galaxy S 4] wtherrell:
It's not an also. It's what it does. The modem software is the radio software.
[Verizon Samsung Galaxy S 4] ymDroid:
HELP!!

I screwed up really bad,

I flashed the NC% modems and it didn't fix the wifi audio/Skype issue.

So I flashed the MK2 non-HLOS, and the wifi is BRICKED.

I click it and it won't toggle WIFI on. Now I can't skype, text, email....

I'm overseas for three weeks and this is the only way to commuicate with my family.

What do I do?

Please help!
[Verizon Samsung Galaxy S 4] ymDroid:
Fixed it.
[Verizon Samsung Galaxy S 4] wtherrell:
Try flashing a regular NC modem (not the non-hlos version) and then flash the NC2 wifi module fix.

---------- Post added at 02:16 PM ---------- Previous post was at 02:11 PM ----------

Please fill us in on how. Perhaps I misunderstood your problem.
[Verizon Samsung Galaxy S 4] ymDroid:
Thanks.

I put SELinix to permissive, flashed the NC2 fix, flashed the NC5 modem, then set SELinix back to normal.

So wifi is toggling again, but the wifi audio over skyoe/hangouts isn't working still.

I wonder if anyone else is having this issue?

---------- Post added at 02:32 PM ---------- Previous post was at 02:19 PM ----------

Flashed those over SS 3.72

So I upgraded from MK2 to NC5.

And then I left left overseas. We dont have mobike data here, only wifi. So I keep my phone on Airplane mode, wofe the wifi on. This way I can still check emails, text over Hangouts, and video chat over Skype and Hangouts.

The problem is that when I call the family over Skype or Hangouts, the video is perfect but my audio comes across to them garbled. Like a chipmunk almost.

My mic is fine. I could make calls, record video, but not chat over wifi. It worked fine on MK2/4.3. I thought it was a wifi issue, but reflashing the NC5 modem didn't help, the MK2 non-HLOS kill the wifi toggle, and now Im back to NC5, but video chat is still working.

Guess I should have tested it before I left.

Could someone who upgrade from MK2 to NC5 turn off thier mobile data, and make a Skype or Hangouts video call, and tell me if the other person can hear you clearly?
[Verizon Samsung Galaxy S 4] vonhulio:
So... I finally decided to update from my trusty MDK radios. I selected the NC5 modem only, and flashed from TWRP. Upon boot, I immediately noticed that I could no longer make or accept calls. Everything else appears to be working fine; i.e.4G mobile data, wifi, etc. I have since tried every modem in the OP to no avail; even the MDK modem. Still can't make or accept calls. I've tried switching to several different ROMS with full wipes. Same problem every time. What the hell happened....? Anybody.....?
[Verizon Samsung Galaxy S 4] gpz1100:
^^Is the rom you're using based on NC5? If not, try a baseband based on your rom.

What exact file did you flash?
[Verizon Samsung Galaxy S 4] ebsk8er06:
If on mdk bootloader flash mdk with nonhlos modem and all should be good

---------- Post added at 08:10 PM ---------- Previous post was at 08:10 PM ----------

Baseband has nothing to do with rom
[Verizon Samsung Galaxy S 4] thesoldier:
You probably flashed the one with nonhlos. Go back to that thread, flash the MDK + NONHLOS, then flash NC5 without nonhlos.
[Verizon Samsung Galaxy S 4] LowaEastSide:
Hey, in need of help.

Bless.
[Verizon Samsung Galaxy S 4] vonhulio:
Fixed!

You guys are truly awesome. For you to take time out of your holiday weekend to help me out, I'm truly humbled. I'm now rocking NC5 and my radios have never worked better. Both of you were exactly correct. I must have initially flashed the nonhlos version as you said (I did in fact have it on my SDcard for some reason). Anyways, how did you know this? I thought I knew my stuff, but this was apparently over my head. I tried to find an explanation for regular vs. NONHLOS but kept coming up empty. Thanks again guys; you rock. :good::good:
[Verizon Samsung Galaxy S 4] gpz1100:
From researching this in month's past, my understanding is the non-hlos.bin handles the lte and wifi radio portions of the firmware. HLOS usually refers to High Level Operating System.

I am running Hyperdive 18.1 on a Verizon Galaxy S4 with the I545VRUFNC5_modem retail modem.

Is the developer edition I545OYUFNC5_modem that much better and worth flashing? I am in a bad coverage area.
[Verizon Samsung Galaxy S 4] wtherrell:
I couldn't tell any difference, but it's so easy to give it a try.
[Verizon Samsung Galaxy S 4] syintiphic:
Give it a try. I tried it and I noticed that my 4G kept dropping and I would have to toggle airplane mode to get it back. I'm now on the regular NC5 modem and all is working well.
[Verizon Samsung Galaxy S 4] s44:
Retail MK2 is still the gold standard. Older ones may be better for 3G but losing AWS isn't worth it.
[Verizon Samsung Galaxy S 4] major payne:
I apologize if these are stupid question(s). I'm knowledgeable on some things and a noob on others.

1. If i flash any modem on my MDK will that effect my being able to sell as a mdk s4?

2. I'm running Bonestock 4.3 S4 2.1 what radio's can i use?

3. What the best modem to run on T-mobile in phoenix?
[Verizon Samsung Galaxy S 4] bryantjopplin:
Any radios (modems) , not bootloaders.
[Verizon Samsung Galaxy S 4] bryantjopplin:

[Verizon Samsung Galaxy S 4] Spookymyo:
1. No. Changing your modem doesn't change that. You can flash back to mdk whenever. Just don't take any ota's.

2. Any of them both retail and dev.

3. Only person that could tell you that is you. You'll have to figure it out by flashing several of them and seeing which one gives you the best results. It can be different for every phone.
[Verizon Samsung Galaxy S 4] Balian67:

To All:

How to modify the OTA zip to make it just flash the new modem and hlos:

I prepared this zip by modifying the OTA zip, this zip updates your modem and hlos to VRUFNG6 using the method from the OTA zip.

VRUFNG6-modem-hlos-from-ota-example.zip

will only work if currently both modem and hlos are VRUFNC5, also flashing the above zip will also upgrade hlos which will cause problems for users so I recommend either flashing the VRUFNG6 modem zip provided by giglie above or from me in the OP. This modified ota zip is mainly posted to be used as an example of how to get the modem and hlos from an ota zip.

Thanks, but as this being the 1 year anniversary of this thread, I figured I would teach users in the future how to do this, being that I will be moving on from this device soon. Also since you've accused me or kanging from you in the past, I figured posting the above modified ota zip would also exonerate myself from any potential claims of having taken the modem and or hlos from the zips you have provided above.
