Not sure which bootloader Im in.

I'm using safestrap and I have flashed different roms, kernel and modem over the last few months.

Right now, my baseband shows I545VRUFNC2 and Builds number is KOT49h.I545VRUFNK1.

Firstly, how do I know is my boot loader?

Secondly, I need to get the right modem for my Galaxy S4 VZW on 4.4.2 ROM. I say that because I have flashed modem not knowing if it's was right for the device or not.

Once I get the modem that is new and will work for my device, I will not want to mess with it again.

If I flash a modem on Stock slot, would that modem be used for any Rom installed on different Rom Slot?

Every time I download the Developer Edition NC5 modem it only has 21 kbs not 21 mbs. Is there another link?
[Verizon Samsung Galaxy S 4] gpz1100:
Use the blue pill, not the orange one.
[Verizon Samsung Galaxy S 4] Surge1223:
I think I may have posted the developer edition nc5 zip on devhost back when they were semi tolerable and not a horrible host.

The good news is I believe this is the only modem I posted on devhost, the bad news is I don't know If I still have a zip of the developer edition nc5 modem handy. I will search for it and re-upload to a dependable, non-shady host. If anyone has a link for people in the mean time that'd be awesome.
[Verizon Samsung Galaxy S 4] robn30:
I'm running Hyperdrive RLS20 on Verizon NC5. I don't have a Loki'ed MDK bootloader. My baseband is NC5, can I just install the latest NK1 modem using safestrap? Or is there something else I need to do? I know when using SS and Hyperdrive I've always had to flash the NC5 Modules after upgrading HD. Will I need to do this for NK1, using NK1 modules? Thanks.
[Verizon Samsung Galaxy S 4] robn30:
Went ahead and flashed the NK1 modem file and all seems to work. Is there any advantages of the NK1 modem compared to NC5 baseband? Thanks.
[Verizon Samsung Galaxy S 4] ThaRockstar007:
I'm on RLS20 with NC5 baseband and modem. I've tried mounting system in SS 3.72 and then flashing googlies wifi fix and it still won't turn on. Any other suggestions?
[Verizon Samsung Galaxy S 4] npjohnson:
3.72 is incapable of flashing the WiFi fix, as it flashes non-hlos partitions, which 3.72 cannot do. Upgrade to Muniz ris 3.75
[Verizon Samsung Galaxy S 4] cognitivedissonance:
Although I don't know the answer to your question, it seems (based on minimal reading from a couple pages earlier) that the primary differences you (may) experience are with compatibility.

Here are the relevant posts that I saw (I started here, on page 85 withcomment #841

I'll try to summarize,

1) There's mention of SELinux and 'enforcing' / 'permissive' issues with NK1 (not even sure what SELinux, 'enforcing' or 'permissive' are tbh)

2) Someone mentions that sdcard permissions don't always work on NK1

3) Someone says that Xposed Framework and Safestrap have issues with something caused by NK1 (this again has to due with SELinux, 'enforcing' and 'permissive' I think)

4) Someone says that Google Edition Roms will have lots of app crashing with 'enforcing' and "needing kernel hooks" (again, not sure what any of that means)

Hope this confuses you as much as me helps!
[Verizon Samsung Galaxy S 4] ThaRockstar007:
I flashed NC5 modules then Gogolies NC55 wifi fix then NC5 modem all thru safestrap 3.72 and got wifi working. I tried just the fix and modem and it never would work til I flashed the modules. Worked for me
[Verizon Samsung Galaxy S 4] npjohnson:
Then what your setup needed from the WiFi fix wasn't the non-hlos. Many setups need that file to flash to work correctly. Plus, if you were on NC5, then the NC5 WiFi fix wouldnt have to flash the non-hlos, as it has the NC5 non-hlos preinstalled!

The NK1 modem does not cause these issues. The Full NK1 build & kernel cause some of these issues. The NK1 modem brings extended XLTE support. & WiFi stability fixes according to Verizon.
[Verizon Samsung Galaxy S 4] cognitivedissonance:
Thanks for the info. Maybe I'll give them a shot then. I'm on the MDK bootloader running a custom kernel, GPE 4.4.4 ROM and currently have the NC5 Dev Edition radios. I shouldn't have any issues, correct?
[Verizon Samsung Galaxy S 4] npjohnson:
Nope. Just don't flash the Non-HLOS package, just do the modem. And the clear cache and dalvik. Should be good.
[Verizon Samsung Galaxy S 4] robn30:
I didn't flash the entire ROM for NK1, I just flashed the modem portion. I haven't had any of the issues described. I am running Hyperdrive RLS 20 on a Safestrap platform. I unfortunately don't have the Loki'ed version, wish I did.
[Verizon Samsung Galaxy S 4] Michaelmansour1997:
Need .tar

can someone please explain to me how to convert the zip nk1 modem to a tar, so that i can flash in odin, i am on stock rooted, but i do not want to install safestrap, and i am trying to flash the modems from Odin.. any help would be much appreciated.
[Verizon Samsung Galaxy S 4] 760hacker:
Anyone extract the new goods from the OTA?
[Verizon Samsung Galaxy S 4] vt0r:
Have a link to the OTA? I'll extract the modem and HLOS and package them up if I (or someone) can find it.
[Verizon Samsung Galaxy S 4] 760hacker:
Can't find it. if i do capture it i'll be sure to post a link. Thanks for the offer to zip it up.
[Verizon Samsung Galaxy S 4] GamerOnOne:
So I flashed nk1 and lost lte.

I tried going back to stock and nothing

Also tried going back to nc5 and nothing

Changed bootloader, mod, and modem

Running hyper drive latest version now.

I tried restoring old back up and it didn't help

Factory reset

*228 to reprogram

Fully uprooted and did Ota update as well

Lte did show after flashing nc5 but wen straight to 3g.

I never had this issue before, any help?
[Verizon Samsung Galaxy S 4] ahoslc:
*228 fry's your sim on S4 I had the same issue also seen others. Go get a new sim card for free and your issues will be solved.
[Verizon Samsung Galaxy S 4] cognitivedissonance:
Whoa... I never knew about that. Does it actually fry the card, or could he just call in and have them reset his service or something like that?

I'm glad I read this though, I probably would've tried dialing *228 too, and my closest Verizon retailer is about an hour away.
[Verizon Samsung Galaxy S 4] ahoslc:
Nope most of the time it requires a new sim nothing on phone they can do about it.
[Verizon Samsung Galaxy S 4] GamerOnOne:
Honestly, that's what I figured but was trying to make that my last step, lol. Thanks
[Verizon Samsung Galaxy S 4] amoeller:
I found this tar of the OC1 modem however it has the non-hlos in it and you shouldn't flash this tar if you are not already on OC1. I'm still on MDK so I'm only interested in the modem.
[Verizon Samsung Galaxy S 4] FernBch:
It doesn't "fry" the card, it just breaks LTE. These phones should never be updated with *228 as the system does it automatically. You'll need to go to a corporate store and have them replace the SIM.
[Verizon Samsung Galaxy S 4] ahoslc:
No modem extracted yet?
[Verizon Samsung Galaxy S 4] vt0r:
No OTA link yet?

If you have a link, let me know. I'll extract and zip it up after I get home tonight.

EDIT - Found the OTA. I'll create and upload the zips shortly, then I'll have Surge add them to the OP.

EDIT2 - Here are the links for modem only and modem + NON-HLOS zips for VRUGOC1:

Modem only: https://www.androidfilehost.com/?fid=23991606952594946

Modem + NON-HLOS: https://www.androidfilehost.com/?fid=23991606952594947

MD5sums are on the AFH pages, and I've verified the ones displayed on the site match the zips before uploading. As always, remember to ONLY flash the modem + NON-HLOS zip if your bootloader is already on VRUGOC1 (it's not). I'll get in touch with Surge and have him update the OP whenever he can.
[Verizon Samsung Galaxy S 4] GamerOnOne:
Well if it's rooted will they still just give a Sim?

It doesn't have insurance on the phone since it's been bought off someone else awhile ago.

I'm use to prepaid so I'm normally dialing *228.
[Verizon Samsung Galaxy S 4] FernBch:
My kids have done it to both of my phones. Just took them to the store and they hooked me right up.
[Verizon Samsung Galaxy S 4] wavedashdoc:
Has anyone tried just the modem OC1 on a stock or Kitpop 1.3 based on 4.4+? Does it work, or should we just avoid this entirely to avoid issues?
[Verizon Samsung Galaxy S 4] amoeller:
I have the OC1 modem (just modem not with NON-HLOS) installed and running without issues on GPE 5.0.1 with MDK bootloader.
[Verizon Samsung Galaxy S 4] FernBch:
Running the OC1 modem only on CM12.1. Seems good so far.
[Verizon Samsung Galaxy S 4] masters:
I'm on NK1 (From MDK) have you noticed any change or difference in reception with the OC1?

Seems the NK1 modem I am on was worse than the stock MDK.
[Verizon Samsung Galaxy S 4] 1BigLoser2:
OC1 working fine on 5.0.2!!!???
[Verizon Samsung Galaxy S 4] FernBch:
Haven't made but a couple calls today and they were around the house (work 4 10's get every Friday off). The real test will come Monday through Wednesday at work. My service area is 10k sq miles in eastern AZ/western NM (elec coop) and I'll pretty much cover it next week.

I haven't switched the NONHLOS, either but I've tried pretty much all the modems. NG6 was the worst and NK1 was pretty good for me. If OC1 doesn't pan out I'll drop back to NK1.
[Verizon Samsung Galaxy S 4] dunderhead:
I'm still on NC5. Do you recommend installing the NK1 modem? I can always flash back, correct?

Edit: nevermind, just flashed the OC1 modem, and everything seems to be working fine.

Hyperdrive RLS21 (Android 4.4.2)

NC5 bootloader, OC1 modem

Safestrap 3.75
[Verizon Samsung Galaxy S 4] npjohnson:
No ones boot loader should be OC1... And if it is, they cannot flash a zip due to not having a way to root..
[Verizon Samsung Galaxy S 4] musicfreak190:
Hey I am on MDK bootload with CM12.1.

Do i need the non hlos or just regular radio?
[Verizon Samsung Galaxy S 4] GamerOnOne:
Yeah they didnt care that ps1 boot animation was loading with 320dpi and modded theme lol just gave a sim right away.
[Verizon Samsung Galaxy S 4] FernBch:
Just the regular one (modem only). You have the MDK bootloader so you should have the MDK NONHLOS.
[Verizon Samsung Galaxy S 4] musicfreak190:
Thanks! Flashed oc1. Hopefully i won't grt stuck in these weird no cellular States anymore. Sometimes my signal icon would show an explanation mark and show no signal. Airplane mode or toggling data did nothing.

Reboot were ny only option.

OC1 BE MY HERO :)
[Verizon Samsung Galaxy S 4] FernBch:
I've been running it since Saturday and it has been good so far. The real test will come Wednesday when I go to New Mexico. I'll pass through a couple "fringe areas" and a stretch where CellOne is the only signal. If I pick up VZW in the fringes and everything automatically comes back after leaving CellOne territory I will say it's good.

That was the test when I went to Nk1 and passed over NC6.
[Verizon Samsung Galaxy S 4] cognitivedissonance:
I'm rocking the MDK bootloader, alucard kernel, and GPE 4.4.4 ROM. Been on the dev edition NC5, and I just flashed the OC1. I'll be back with my notes on it in a few days. My apartment has crappy service, so if the OC1 is markedly better, I'll notice.
[Verizon Samsung Galaxy S 4] anewday:
Not much difference with oc1.

Modems and GPS?

Bizarre issue. On CM11 jflte nightly from April'15. The phone works fine here in Phoenix, and in Portland, NorCal, etc. When I travel to Korea or Germany (GSM, not CDMA locations coincidentally), then the GPS seems like is it completely non-functional. GPS Status flashes up the active/searching icon in the notification bar for about 1 second, then it goes away. The GPS Status display shows zero satellites forever (tried for 10min). Not even one satellite showing on the signal strength bar or radar map. Zippo.

Tried deleting, resetting and downloading A-GPS data (via a wifi connection, not mobile data) does help. Note that I have mobile data roaming off, but cell service on and I can make/get calls and texts. Arrive back in the States and the GPS works again. Can't debug something that ain't broke! Damn it!

I'm not finding this issue in any forums. Is this a known issue? I'm on the MDK Baseband version. Will changing the modem package potentially fix this?
[Verizon Samsung Galaxy S 4] FernBch:
I've been running the OC1 modem for about a week. At first I thought I noticed a slight increase in data speeds but not much change in cellular service. Today I did notice that it doesn't seem to be quite as good as the NK1 was. I may reflash the MDK+NONHLOS and try OC1 again (doing this helped once before) but if there is no change I will return to NK1.
[Verizon Samsung Galaxy S 4] roadblock217:
If I'm on stock, unrooted OC1, am I able to flash an older modem? Reason being..I've noticed problems in my area with the OC1, but no problems with the previous modem...
[Verizon Samsung Galaxy S 4] skepticmisfit:
no

unless you did the neutered odin tar which had the nk4 bootloader. if you took OC1 via OTA update, you can not flash a new modem.
[Verizon Samsung Galaxy S 4] roadblock217:
Gotcha, thanks. I tried using the regular recovery and it didnt work. I used to have an S4 but don't remember the specifics of stock and twrp for modems and such...I am going to try using the stock tar to reflash and see if that helps..
[Verizon Samsung Galaxy S 4] cognitivedissonance:
After a decent amount of testing of the NK1 and the OC1 modems, I'm sticking with the OC1. Details about my setup are in the post I quoted, above. Whether it's that much better than the NC5 or NK1, I really can't say, but it seems to be more reliable. Might just be my imagination though.
[Verizon Samsung Galaxy S 4] Nath5:
With OC1 WiFi doesn't seem to be able to turn on. Any ideas?
[Verizon Samsung Galaxy S 4] masters:
MDK bootloader (not safestrap) and on a CM12.1 rom

Which one and what is the purpose of the modem only vs the nonholos.

I previously flashed and am on the modem only nk1 baseband.

I am basically trying to decide if I should try oc1 and what the differences are.
[Verizon Samsung Galaxy S 4] Surge1223:
Modem only is modem only, hlos tends to mess with kernel compatibility so use modem only.

Also apparently I didn't post oc1 here yet? It's on my afh, I just haven't updated OP with a link yet.

So if someone is freaking out "OMGz he hasn't posted new modem yet!!?!?! NOOooOOOOo" it's definitely findable lol.
[Verizon Samsung Galaxy S 4] masters:
Flashed the OC1_modem

Now I have no signal (in the triangle) and Preferred network type in the Mobile network settings defaults to 3G. If I change it, it changes back but still no signal.

Went from

MDK - FNK1_modem - OC1_modem

EDIT: Oh, wow, after a really long time (20+minutes) I now have LTE. I had given up on it. :eek:

EDIT 2: Darn typed to soon.. Now back to no service and something about "restricted voice service changed."
[Verizon Samsung Galaxy S 4] 1BigLoser2:
Flash NK1 back.
[Verizon Samsung Galaxy S 4] masters:
Did that, weird that I have data but not voice now. They say the voice goes over the 1x network.

Just strange I show signal LTE but can't get calls in or out

It will even sometimes say the baseband version is unknown .

Later today I am going to try to ODIN back to MDK and see if that gives back my cellular voice.

I don't really want to have to buy a new phone.
[Verizon Samsung Galaxy S 4] vt0r:
Before you do that, flash the MDK modem and non-HLOS (but only if your bootloader is really MDK), then flash the modem only zip of whichever modem you actually want to use.
[Verizon Samsung Galaxy S 4] Surge1223:
I second this motion.
[Verizon Samsung Galaxy S 4] masters:
:(

Put it baseband back at MDK non HLOS, on a CM12.1 Rom

Still Data works, good signal with LTE showing.

No Cellular Voice, No Txt messaging.

My workaround is using the Hangouts Dialer since I use google voice to make calls on the Data.

After I try a few more things, Next mission will be to Odin back to a stock MDK, go through that process and see if it works. Then flash back to my last known good backup that worked before.

Switching between modems is easy. You can flash just about any one of them no matter what baseband your on. I am still on NC5 base band but have OC1 modems, I can use MDK ones if I wanted. But I want to try the newest one though!
[Verizon Samsung Galaxy S 4] tshelby73:
Switching yes easy but I would like to have the of1 in case it is actually the best and its not available yet so I can't go back. I am going to do a little more research and see if I can figure out how to extract.

I'd recommend shooting a message to a few of the guys who extracted previous versions. I'm sure they could point you in the correct direction.
[Verizon Samsung Galaxy S 4] tshelby73:
I've been having some issues with not switching back to 4g and on oc1i had it actually not recognize sim. I reinserted sim and reboot fixed it.

Reflash the MDK+NONHLOS package then flash the modem only of choice. I had a similar issue in the past.

Sent from S4 using the better than it was then they jacked it again Tapatalk
[Verizon Samsung Galaxy S 4] blackops11252:
Sounds like a sim problem and not modem.
[Verizon Samsung Galaxy S 4] cognitivedissonance:
tshelby, maybe flash the NONHLOS version of the NK4 (if that exists... I'm too lazy to check) and then the modem of your choice.

Alternatively, just go grab a new sim card from Verizon. They're free if it's a retail Verizon location (if you're rooted/ROMed, keep an eye on what they're doing with your phone so they don't eff anything up - most of the ppl at the stores don't fully know what they're doing)
[Verizon Samsung Galaxy S 4] FernBch:
Didn't realize. You want your bootloader to match with the nonhlos. Try the same only use the nk4 nonhlos package first. If that isn't the solution search the thread for your ROM, there may be a solution there.
[Verizon Samsung Galaxy S 4] vt0r:
Anyone have a link to the OF1 OTA? I'll extract and package the modem if so.

Not all galaxy phones support downgrading basebands. For example, sch-r530, no downgrading. Sure it'll flash successfully but you'll have no signal. Fortunately this is not the case with the vzw s4 thus far.

TWRP and Modems??

Okay folks, here come the ever reoccurring set of ignorant question. Kindly humor me. This should be quick…

I have an SCH-I545 / Verizon GS4 with the MDK baseband (as listed in About phone), and I assume MDK bootloader, running CM12.1. I'm also using TWRP V2.8.4.0. I have regularly flashed CM11 and CM12.1 builds, and make Nandroid backups using TWRP before each CM flash.

The title of this thread is "[MODEM][Zip] Modems for Loki'd & Safestrap roms", and I can't be sure that my device qualifies.

Simple questions:

1) Can I grab a Modem package from the beginning of this thread and simply flash the .zip file using TWRP?

2) What is a recommended Modem .zip to install?

3) I gather that the various modem zips can be switched between freely, without wiping anything else in the phone, correct?

4) And finally, has anyone heard of this GPS problem ([Q] Dead GPS when out of the country), and will a newer modem possibly fix this? Also having flaky Bluetooth share crashes on CM12.1. I'm not alone.
