Network Extender Issues?

I flashed the MJ7 modem (was on MDK), and ever since then, if I try to make a call at home under the network extender, my S4 will kick me off the extender (the little house symbol above the signal bars will disappear, and I notice a big drop in voice quality). I tried flashing back to MDK, but the same thing happens. It was fine before.

Has this happen to anyone else? Any suggestions?
[Verizon Samsung Galaxy S 4] Surge1223:
Try flashing the mdk non-hlos and modem zip package. Then clear cache/dalvik and reboot.
[Verizon Samsung Galaxy S 4] oilfighter:
Thank you for the suggestion. Unfortunately, it didn't help...
[Verizon Samsung Galaxy S 4] Alxoom33:
Do what surge suggested and then flash the mdk modern alone (w/o non-halos).
[Verizon Samsung Galaxy S 4] Raygray123:
Do any of these modems allow band 4 AWS?
[Verizon Samsung Galaxy S 4] klabit87:
The mj7 modem does.
[Verizon Samsung Galaxy S 4] zetachi:
Links dead?

Could not access backend storage
[Verizon Samsung Galaxy S 4] klabit87:
Works fine on my end.

Which one are you trying to get?

Let me know if you need a mirror or try another browser.
[Verizon Samsung Galaxy S 4] zetachi:
hmm working now :)

Thanks

[MENTION=4939386]Surge1223[/MENTION] Will you be posting a new set of modems for the new MK 4.3TW OTA update that was just released in Europe?
[Verizon Samsung Galaxy S 4] Surge1223:
MK 4.3 ota..? Let me take a look at the files. I ll look for the thread and get back to you.
[Verizon Samsung Galaxy S 4] Lou 270:
I just got spanked in another thread and that guy said cm10.2 could not be used in safestrap so what is different about this and why can it be done all the sudden
[Verizon Samsung Galaxy S 4] riker147:
Not really sure what you're talking about. This thread is for Modems/Radios only.
[Verizon Samsung Galaxy S 4] Lou 270:
Oops posted in the wrong tread
[Verizon Samsung Galaxy S 4] Alxoom33:
I believe it is MJ9

Newer one...MKF
[Verizon Samsung Galaxy S 4] s44:
Those are GSM radios. Only Verizon radios should be flashed to the i545, no matter what ROM you're running.
[Verizon Samsung Galaxy S 4] Alxoom33:
Got it. Thanks.
[Verizon Samsung Galaxy S 4] swordmastr54:
I've been getting really bad service like 2 bars everywhere I've tried some of them but I'm wondering what I can do to to get better service I'm running a 4.4 ROM and me7 would the mdk one be best or what one do you recommend?
[Verizon Samsung Galaxy S 4] jromash:
How do you know your bootloader

Couldn't find this answer, but I feel like it should be easy

How do you know which bootloader you are on... had some issues recently when updated to new nightly of CM. Think I have it fixed but it was a shot in the dark which bootloader I was on. I had previously updated to J7 so I couldn't look at baseband.

I assumed it was MDK, or ME7 so I started there with the Nonholos MDK seemed to get my phone back up and running, so I guess that was it, but I was scared to flash the ME7 nonholos per the instruction in the OP.

thanks for clarifying in advance
[Verizon Samsung Galaxy S 4] scryan:
ummm, I don't think your asking what you mean to...

Are you trying to restore your device with official firmware or are you flashing custom rom?

If you were using CM you phone was originally MDK.

MDK is the only one that can do custom recovery with out safestrap, so its the only one that can flash none TW roms. DO NOT INSTALL ANYTHING OFFICIAL OTHER THEN MDK or you will trip a qfuse and will not be able to flash custom recovery again, and will be stuck with only safestrap/unable to change kernals.
[Verizon Samsung Galaxy S 4] jromash:
That makes sense... from what I read in the CM forum it was that particular nightly that was causing radio problems.

But I was freaking out because could not find a place to verify what my bootloader version... since was on CM I knew it had to be MDK or ME7

Thanks again for the clarification
[Verizon Samsung Galaxy S 4] PFusion:
rightssg which

I'm a little confused please bare with me because I've been out of the loop for a few years. I've tried to read as much information but a lot of is fragmented through out the forums.

I've attached a picture of what I'm currently running. I'm running ClockWorkMod Recovery v. 6.0.3.2 and HyperDrive 10.0. Lately I haven't been able to connect to any 4G singals even when I am close by the tower. I'm hoping I could upgrade my radio which is the baseband correct? Well I'm hoping that will help fix any issues I've been having. I'm also assuming that the Baseband version MJ7 is the latest baseband?

Do I need to do anything special before flashing, and can I just flash using odin or load the zip file from ClockWorkMod Recovery. Will I loose any data when flashing a new baseband, will it effect my rom, or root? Sorry I know some of these questions may be newb questions but again I think this will help a lot of other people who are lost in the fragmentation of information about this.

Thanks
[Verizon Samsung Galaxy S 4] Mightycaptain:
Makes me think you should look at your mobile network settings and make sure you have LTE enabled and aren't in global mode or something.
[Verizon Samsung Galaxy S 4] PFusion:
Well I've tried both Global and LTE/CDMA both are not working. It's interesting though because Verizon Enterprise Solutions Tech support had me make sure it was on global. Anyways... Is MJ7 the best radio currently available?
[Verizon Samsung Galaxy S 4] Surge1223:
I think I literally answered all your questions in the OP. I mean you could probably just read the parts in red and the FAQ section and you'd have all your answers. You can either flash the downloaded zip or extract the modem.bin and flash it under "Phone" in Odin. As long as you're phone model is SCH-1545.

P.s. One of the knocks against CM is that it cant get the same network performance and bandwidth as natively found on Touchwiz.
[Verizon Samsung Galaxy S 4] PFusion:
I've attached my specs

I'm currently have a Galaxy S4 (Verizon) and I have HyperDrive 10.0 installed and clockworkmod installed for my bootloader, and I am rooted.

Can I upgrade my baseband to 1545VRUEMJ7_modem.zip without any problems? Again I've included a picture below with specs.

Thanks for the help!
[Verizon Samsung Galaxy S 4] PFusion:
Surge! Thank you for being patient with me and answering my questions. I'm trying to sort this out the best I can. I've learned a lot of the last few hours. When you mentioned one of the knocks against CM is the network performance, is there any work arounds? How much of a difference do you see in network performance and bandwith as natively found on Touchwiz?
[Verizon Samsung Galaxy S 4] Surge1223:
Yes you can flash the MJ7 modem you referred to. I dont know the status of how cm is functioning on the S4, and I havent installed cm on my s4 for awhile now so I couldnt tell you to be honest. Im sure the difference in minimal, maybe some cm veterans can chime in.
[Verizon Samsung Galaxy S 4] PFusion:
List ougmoin

Thanks again, I've searched for a post about this but can't find it, do you know if anyone has posted details about the differences between each radio? Performance etc.. in your opinion which is the best radio?
[Verizon Samsung Galaxy S 4] s44:
Performance will vary from location to location.

The only blanket difference is that only MJ7 is able to do LTE over AWS. This will massively increase connectivity in dense urban areas like midtown Manhattan.
[Verizon Samsung Galaxy S 4] murph:
Verizon S4 MDK rooted running CM 10.1.3. Used CWM to patch MJ7 radio today. Getting 30+ Mbps DL in NYC. Hellooooooo AWS. Thanks!!
[Verizon Samsung Galaxy S 4] Mightycaptain:
My wife has a stock s4 so I've been able to compare them side by side with the same radios with mine on aosp. Honestly its about the same. Where aosp differs IMO is with data handoffs. It is a lot slower transitioning back and forth from 1x to 3g,4g and WiFi. Signal strength in dBm for voice and data are very similar. Typically aosp is a little stronger in the same place. Just my experience. For typically me7 radio has been the best radio. It holds edge voice and data better than the rest. When I say that I mean on me7 radio I can make calls all around my house, on others have several dead spots. But you won't have aws unless you use the mj7 radio. But I'm definitely not getting aws in my area.
[Verizon Samsung Galaxy S 4] claytonjn:
First off i'd like to apologize if this has been covered already in this thread. I read the OP and skimmed all the pages, but I might have missed it.

I have the Developer Edition S4. Currently I have TWRP recovery, and am running the MK8 4.3 ROM here: http://xdaforums.com/showthread.php?t=2552605

My current baseband is OYUAMDK. Can I safely flash the 1545VRUEMJ7_modem.zip baseband? I know the OP says "ONLY FLASH THE NONHLOS and MODEM PACKAGES OF THE BOOTLOADER YOU ARE ON!" but I haven't figured out yet what exactly applied to the Developer Edition and what doesn't.

Also, I just upgraded to the S4 from the Galaxy Nexus a few days ago. On the Galaxy Nexus there were individual radios to flash for LTE, WiFi, etc. (although usually a flashable zip was made that would flash all simultaneously.) Just to be perfectly clear, "Radio" "Baseband" and "Modem" all refer to the exact the same thing?

Thanks!
[Verizon Samsung Galaxy S 4] Surge1223:
You can safely flash the MJ7 modem. For the purposes of this thread you can assume everything applies the same for all versions of VZW GS4s. I removed the MJ7 NON-HLOS from the OP anyways.
[Verizon Samsung Galaxy S 4] abe_cedar:
dev modem.

Hi Surge,

I have a dev edition which came with the MI1. I wonder if the MI1 version is ok with this device.

Thanks

Abe
[Verizon Samsung Galaxy S 4] Surge1223:
What? Dev editions come with OYUAMDK. What's your full build version? (settings>>about>>build number)
[Verizon Samsung Galaxy S 4] abe_cedar:
I have tried both modems the MJ7 and the MDK on this dev edition. It hangs when it says activating. The phone was never user. I am trying to get the box to see what version was on it. I have tried the tar before. Something must have gone wrong. I can get into recovery and into the rom but no activation...

Any ideas?

tia
[Verizon Samsung Galaxy S 4] equake:
Was this a brand new DevEdition out of the box? What is the entire version number ie all the stuff before MI1?

Thanks
[Verizon Samsung Galaxy S 4] abe_cedar:
I don't have the version anymore it was a OY... MI1. It is a brand new dev edition some friend got last week. He tossed the original box- which had the software. The phone is ok as I have installed philz latest cwm and not the rom. Did the backup but I was not able to restore from it. I have tried beans s4 rom and it did not boot. then I have tried to odin back a version of a Y..MDK. Did not work. I was able to get scotts rooted MDK to boot but it is stuck at activating. the phone restart but no network or wifi. I figured it could be the modem so I have tried several no luck.

I am sure some non dev file is in there and it makes the phone unhappy.

tia

Abe
[Verizon Samsung Galaxy S 4] Surge1223:
Its probably kernel modules related. Unless theirs a new version of the dev edition. Can you open terminal and extract the aboot partition? Ill be able to tell you what device you have and/or see if its a new version.

su
dd if=/dev/block/mmcblk0p6 of=/sdcard/aboot.mbn
[Verizon Samsung Galaxy S 4] abe_cedar:
I don't think I can do that since I cannot get pass the activating screen.

I remember when I tried to flash your tar MDK I got an error when odin was getting the aboot.bin .

Are the any unsigned kernel/newer than MDK?
[Verizon Samsung Galaxy S 4] equake:
Have you tried to ODIN the factory Ml1image?

My 2 cents?
[Verizon Samsung Galaxy S 4] abe_cedar:
No because I don't know where to find one.

Surge,

are the any tar factory images for the DEV device?

I doubt it.

thanks

Surge, new modem in mk2 update?
[Verizon Samsung Galaxy S 4] Surge1223:
Working on it, problem is we need someone already on mk2 to dump it. I posted in q&a asking for it
[Verizon Samsung Galaxy S 4] scarmon25:
Modem.bin posted in general mk2 thread
[Verizon Samsung Galaxy S 4] Surge1223:
New modem zip is up! MK2 works, tested myself

Enjoy!
[Verizon Samsung Galaxy S 4] FernBch:
You da man
[Verizon Samsung Galaxy S 4] mtown_cyclone:
Anyone tried MK2 yet?
[Verizon Samsung Galaxy S 4] 0reo:
Works fine for me so far. no noticeable difference in the first 15min.
[Verizon Samsung Galaxy S 4] jorceshaman:
MK2 is working fine for me. Haven't noticed much difference from the last one. From reading the update information I think the main improvement is stability in Canada and Mexico.
[Verizon Samsung Galaxy S 4] igacek:
This might be a placebo, but after flashing MK2, my 4G signal at home went up a bar. Usually I got 2-3, now I'm getting a steady 4 it seems. On speedtests with the previous modem, I was averaging around 5-7mbps down, and around 5mbps up. With MK2, I got 12mbps down, 8mbps up.

Again, I don't have any science to back this up besides my previous modem experience, but this may have been a decent improvement.
[Verizon Samsung Galaxy S 4] musicfreak190:
Is there an app to see what band you are on?
[Verizon Samsung Galaxy S 4] vwpiper:
Just did speedtest.net and MK2 is markedly better.
[Verizon Samsung Galaxy S 4] stuckintheskull:
Can I use Odin to flash latest modem on a MJ7 device?
[Verizon Samsung Galaxy S 4] swordmastr54:
I assume that its not going to lock my bootloader if I get the mk2 and flash it?
[Verizon Samsung Galaxy S 4] scarmon25:
Nah. It's just a modem.
[Verizon Samsung Galaxy S 4] TemporalShadows:
Anybody else have terrible voice service on mj7? I'm wondering if it was a hardware issue or the update. I warranty replaced my phone and I'm on me7 now, but don't want to update at all if it is the radio firmware that caused it. If MK2 corrects the issue, I'd love to try updating the radio.
[Verizon Samsung Galaxy S 4] abe_cedar:
Surge,

I was able to get into the rom. It says MDK. This is scott's MDK stock rooted deodexed. So that is the kernel that is inside.

baseband unknown...

soooooo

I have to have a radio that works...

Any ideas?

TIA
[Verizon Samsung Galaxy S 4] Surge1223:
Yeah if you want to. Extract the modem.bin and flash in Odin under phone
[Verizon Samsung Galaxy S 4] TheCelt:
hmmm... I just tried flashing the MK2 modem with ODIN 3.07, failed the security check. I'm rooted on MJ7.

---------- Post added at 04:41 PM ---------- Previous post was at 04:39 PM ----------

d'oh... nvm, I have knox frozen. I bet that's not going to help much when flashing a new modem.
[Verizon Samsung Galaxy S 4] Surge1223:
Hmm, weird alright maybe hold off on Odin flashing let me double check the file. I couldve sworn i modded it to be signed...
[Verizon Samsung Galaxy S 4] TheCelt:
Welp, wasn't knox. still got same Auth failure. Maybe it got corrupt during DL?

Thx for checking into it Surge!
[Verizon Samsung Galaxy S 4] Surge1223:
No problem, still gotta double check a few things but it still appears to be signed correctly. Ill try Odin flashing it w/ 3.09 and Heimdall ill report back.
[Verizon Samsung Galaxy S 4] RedBullet:
On VRAUMDK, ok to flash to MK2?

from what I can tell these are just radios, so there should be no harm in flashing them right? I can always go back and flash a different one if I need to and it won't be messing up bootloader, custom recovery, or anything like that?
[Verizon Samsung Galaxy S 4] Mightycaptain:
No won't cause issues like that. Is just a radio.
[Verizon Samsung Galaxy S 4] Surge1223:
Well this is weird. MK2 fails in odin, MJ7 works fine in odin. I swear MK2 is signed properly I triple checked. I even tried it as a tar.md5 in ap. Something tells me they've either upped security or I made a small mistake somewhere. Then again if I made a mistake then how did Odin know I was trying to flash mdm..? Weird, im looking into it.

P.S. Those on MI1, ME7 and MDK, dont worry you can still flash these modems back and forth with recovery, I just went from MK2 to ME7 to MK2 to MJ7 and back to MK2 with no problems.
[Verizon Samsung Galaxy S 4] abe_cedar:
So which one works in odin beside mj7?
[Verizon Samsung Galaxy S 4] jorceshaman:
As long as you extract the modem file from the zip, everything EXCEPT MK2 I believe. I just flash in TWRP though.
[Verizon Samsung Galaxy S 4] mikehinnenkamp:
MDK with CM10.2, Which radio?

Hey guys,

I just put CM10.2 on my S4 today. good so far, I am still on MDK for my Baseband. I noticed that after installing CM i get worse reception then i did with the stock 4.2.2. Anyone have experience as to which radio firmware i should try? From what I have read my best bet is the 1545VRUEMJ7_modem.zip, can someone verify that? And i want to make sure i can install that Zip via my TWRP recovery (2.6.3.1).

If i have issues i can just flash back with the 1545VRUAMDK Modem zip file? Or would flashing back to stock mean using the apnhlos file?

Thanks!
[Verizon Samsung Galaxy S 4] Mightycaptain:
Its not worse. Aosp ROM's reflect in the bar strength which ever signal is worse. Usually data. TouchWiz reflects the stronger of the 2 usually voice. Check out an app caused advanced signal status. Check your strength in the same place on both aosp and TouchWiz. You'll see they are the same more or less. The only other difference IMO is the aosp is worse or slower for data handoffs. 3g to lte or to wifi and back again.

As to which radio is better. I'd say it depends on where you live. Me7 radio has proven the best for me. There is no aws in my as area, if you have that maybe mj7 or mk2 would he better for you. Others will say it's any affects you think you have will be placebo. But I can make calls all over my house with me7 and drop calls with every other radio. I live in an edge area. I think your results will vary. Just test and see.
[Verizon Samsung Galaxy S 4] mikehinnenkamp:
Radio Q

OK, that may be the case; but it does seem to be slower on 4G too, my area has almost complete 4G service where I am, may not be AWS though; could just be me having OCD. So did you use the regular radios to flash yours or the non-hlos ones? I should be good to jump back and forth without breaking anything on my phone? Do you use TWRP or CWM to flash those zips?

Thanks for your help with this.
[Verizon Samsung Galaxy S 4] Mightycaptain:
TWRP 2.5.0.2. Surge has a little quote above the flashables. "Flash these 99% of the time" Use those. Yes jump all around. It's just a radio.

As to speeds. I don't know exactly. My wife has a stock s4. Side by side in the same places sometimes I'm faster sometimes her. I'd say it balances out in the end.
[Verizon Samsung Galaxy S 4] FernBch:
Does anyone know where I can get the MK2 radio w/ NONHLOS.bin?
[Verizon Samsung Galaxy S 4] scarmon25:
I've been wondering the same. I would be willing to try one made by surge
[Verizon Samsung Galaxy S 4] FernBch:
Especially since CM merged the MK2 fingerprint into CM11 jfltevzw.
[Verizon Samsung Galaxy S 4] scarmon25:
Exactly. I am more than willing to try one that has been made properly.
[Verizon Samsung Galaxy S 4] FernBch:
Not unless I beat you to it. :)
[Verizon Samsung Galaxy S 4] ryanw5489:
Ok I'm totally new to this modems thing!

I have never taking a OTA Since the s4 came out and Im running Hyperdrive Rsl11. So could anyone help me out on how to do this! Also which one I should grab? And is it best to do this or if everything is good should I leave it alone?
[Verizon Samsung Galaxy S 4] stuckintheskull:
Just flash in recovery. MK2 modem is the latest. You can always flash back in you don't like it.
[Verizon Samsung Galaxy S 4] ryanw5489:
OK but where do I find this. I only see a list but don't see any mk2? Also what exactly does this do or help? And do I have to flash this everything I Reflash a rom?
[Verizon Samsung Galaxy S 4] stuckintheskull:
It's in the OP it ends with "mk2". It could improve your signal. All you have to do is flash in recovery just like a rom. No need to wipe anything.
[Verizon Samsung Galaxy S 4] TheCelt:
Is the MK2 modem fixed? It originally was failing the security check and was resulting in a fail.
[Verizon Samsung Galaxy S 4] Surge1223:
Havent been able to figure out whats wrong with it yet. Im open to suggestions though.
[Verizon Samsung Galaxy S 4] scarmon25:
Is there any way to make a zip that has both modems in it?
[Verizon Samsung Galaxy S 4] jorceshaman:
I'm not a developer but... What's the point in 2 modems in a zip when your phone can only have 1 installed at a time?
[Verizon Samsung Galaxy S 4] scarmon25:
Ones the modem.bin and the other is the apnslos.bin. Both are essential to get the full benefit of the modem update. One without the other is like a burger without the bun.
[Verizon Samsung Galaxy S 4] jorceshaman:
Ah, the 2 parts. I thought you meant like MK2 and MJ7, for example.

My bad.
[Verizon Samsung Galaxy S 4] scarmon25:
Ah. Haha yeah that would be a little crazy
[Verizon Samsung Galaxy S 4] FernBch:
Does anyone know where I can get the update file? I would like to attempt to create a tar.md5 that contains the modem bin and the non-hlos.bin.
[Verizon Samsung Galaxy S 4] mirceab:
Check the thread about the MK2 update. Unfortunately I can't post links yet. Somebody uploaded the update.zip to dropbox and posted the URL there.

You can take the MJ7 non-hlos file (see OP) and apply the binary patch from update.zip using bspatch.
[Verizon Samsung Galaxy S 4] FernBch:
Got the update.zip, I'll see what I come up with in a couple days.
[Verizon Samsung Galaxy S 4] papstar:
Any chance at getting the non-hlos.bin with the MK2 modem?
[Verizon Samsung Galaxy S 4] TheCelt:
Hopefully not a dumb question..... but could you flash one at a time or do both have to be in the same zip?
[Verizon Samsung Galaxy S 4] Surge1223:
Im hesistant to post the nonhlos because a lot of users often dont know what they're doing and despite my warnings in the op they will flash both and end up with wifi problems. I mostly put them up for people to recover but hold up Let me think about it, in the mean time ill post the MK2 modem from the odin tar.
[Verizon Samsung Galaxy S 4] jorceshaman:
Maybe you could post them within a "Spoiler" thing with an extra warning saying advanced users only and no support will be given for the following files or something along those lines?
[Verizon Samsung Galaxy S 4] Surge1223:
Thats a good idea, though it probably wont work and since im a nice guy id end up helping anyways lol. Also I should clarify I don't have the odin tar yet, im in the process of getting it though.
[Verizon Samsung Galaxy S 4] jorceshaman:
It probably won't BUT it could probably ease your mind a bit.
[Verizon Samsung Galaxy S 4] Surge1223:
Well we'll give it a try. Once I have the odin tar which at this rate is going to be 3 hours from now (its downloading)
[Verizon Samsung Galaxy S 4] TheCelt:
Can anyone give a quick explanation as to what the NON-HLOS.bin does? I'm no "advanced" user by any means, but all references to this file seem to coincide with people complaining of wifi issues.

That being said, if one upgrades their modem and experiences no issues... do they also need to flash that NON-HLOS file (making sure they are both of the same build... e.g MJ7, MK2, etc)?

I pulled the modem.bin file from the MK2.tar.md5 on sammobile. Flashed via ODIN with no issues.

As always... TIA.
[Verizon Samsung Galaxy S 4] jorceshaman:
I'm not an advanced user but I know enough to look something up and read about it before flashing. Glance through comments and see if there's any issues that would make me want to avoid something.

And I don't entirely know what the nonhlos is but from this thread I gathered that I should only flash the one for my base (MDK). Which is all someone like me needs to know. I don't understand the people who don't read.

This is a $600 phone, don't turn it into a brick because you're lazy!
