I had the latest kt kernel when I Odin'd to MK2 .. ZERO problems with wifi ...in fact I have had a noticeable performance upgrade since going from mja to mk2 ..I have 4G in places I didn't have previously ..If you are using sacs latest there are reports that kt kernel is not working well for some

---------- Post added at 08:51 AM ---------- Previous post was at 08:45 AM ----------

If you made your back up using Philz you need to go in nand settings and check the Se context 4.3 box prior to backing up otherwise you will get unknown baseband ect..As far as mja not sticking are you powering down completely prior to going into down load mode ? Also with mja after flashing with Odin people ( myself included ) needed to hold down the power Bolton after flash ..so uncheck auto reboot ; after flash says pass hold down power
[Sprint Samsung Galaxy S 4 Android Development] chefy2k4m:
I had mja modem flashed mk2 I have no volume at all. Anyone know a fix? I reflashed the mja and no luck
[Sprint Samsung Galaxy S 4 Android Development] lipps:
Thanks! I'm running latest CM11 nightly, and was on MF9. Followed the OP instructions (left Odin settings on default), flashed MK2, and everything seems to work fine so far. :good:
[Sprint Samsung Galaxy S 4 Android Development] smccall:
When you go into about phone what does yours read mine still says mja. I flashed twice both passed also unchecked f - reset and auto reboot
[Sprint Samsung Galaxy S 4 Android Development] lipps:
It says MK2...
[Sprint Samsung Galaxy S 4 Android Development] smccall:
Mine isn't taking then that's odd

Ok I'm dumb it said not to use the reboot into download option in the power menu and it finally worked. Wifi on stock kernel is working perfectly.

Anyone have issues with loosing root when flashing the mk2 modem? If you did, how were you able to reacheive root?

my wifi is not working after flashing the MK2 modem either. any one found a fix yet
[Sprint Samsung Galaxy S 4 Android Development] socos25:
Mine works at home but not at work. This has been since I got the S4 rooted on 4.3.
[Sprint Samsung Galaxy S 4 Android Development] xxaddictedxx:
anyone tried updating to MK2 with mobile odin? i read back about 10 pages and didnt see anything? i know it worked on previous versions but havent updated since mf9...

edit: flashing with mobile odin pro was successful after the third attempt(had to place .tar in the modem #2 slot :S) . flash broke sound though. went into recovery and cleared dalvik and cache......unsuccessful. reflashing entire rom (slimkat 4.4.2 beta 1.6 weekly with KTs 12/4 build). still no luck.....anyone with a great idea for how to fix the sound?

Edit: flashed back to mja and it did not fix the sound issues. Got home and flashed the mk2 modem via PC Odin and it fixed everything......moral of the story is Mobil Odin doesn't do well with the latter modem versions.
[Sprint Samsung Galaxy S 4 Android Development] dewrust:
had this issue and i had to reflash mf9 via mobile and everything went back to normal

good to hear that using pc odin works better

thanks for the info

edit: SUCCESS
[Sprint Samsung Galaxy S 4 Android Development] Danny DiMarzio:
I tried flashing the MK2 modem only using Odin3 on my pc a couple times, now my wifi isn't working either with the stock deodexed MK2 Rom.

I checked my Baseband version and it still reports that im on the MJA Baseband. It's clearly not flashing correctly.

If anybody has a fix that would be greatly appreciated.
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
Are you powering down all the way ..then going into down load mode after phone is completely off ? I know some people were having problems with mk2 not sticking for them when they were going into dl mode via the power options ..just a thought
[Sprint Samsung Galaxy S 4 Android Development] clshores:
Mine worked for almost 24 hours and then gave up the ghost. No wifi at all.
[Sprint Samsung Galaxy S 4 Android Development] majid25:
Don't we supposed to flash to PHONE instead of PDA like we did for the MJA modem when it first got released?
[Sprint Samsung Galaxy S 4 Android Development] dewrust:
I always use PDA and it works fine for me.. But electronics do have their own "personality" if you will

No two phones are identical
[Sprint Samsung Galaxy S 4 Android Development] xxaddictedxx:
i used PDA when i flashed an have had no problems. all services confirmed working.
[Sprint Samsung Galaxy S 4 Android Development] jonmcginnis:
Hey man, please help...because somehow I must be an idiot...where have you found a Stock Deodexed MK2 ROM? I've been watching for this for days. Have my eyes just missed this somewhere on the forum? I'm on MJA running smoothly but am reluctant to install the MK2 update that pushed to by S4 a week ago. I don't want to break root if I can help it. Thanks sir.

[Sprint Samsung Galaxy S 4 Android Development] mogul420:
hai!

I just noticed im still on MDC and decided to flash to the latest.(MK2) using Odin 3.06. It runs and reboots, but it doesnt upgrade. It stays on MDC.

Help?

EDIT: Unknownforce's instructions are very accurate. I need to l2r before posting.
[Sprint Samsung Galaxy S 4 Android Development] dewrust:
I would say use mobile Odin but its not working 100% (unless you don't mind not having audio)

You have to hold tight till chainfire gets time to update
[Sprint Samsung Galaxy S 4 Android Development] soundimpressions:
Thank you!!! I have the 4.3 Mk2 update and had lost all wifi. It's now fixed!!! I shared the link to this thread on another where people are asking how to fix that problem. I also donated a couple bucks. I wish I could do more, but I'm broke.
[Sprint Samsung Galaxy S 4 Android Development] scott_0:
thx for this! worked great for me
[Sprint Samsung Galaxy S 4 Android Development] evolishesh:
can i flash the mk2 if I'm on mdl modem and still running 4.2.2?
[Sprint Samsung Galaxy S 4 Android Development] godsonbx:
I would like to know the same thing, I'm on MF9 and also have a flashed mod for the hotspot for this specific firmware. If I use odin to flash MK2 will I mess something up on my device and will I lose my hotspot mod.....or can I simply just flash a custom rom and skip all this madness of flashing only modems..
[Sprint Samsung Galaxy S 4 Android Development] evolishesh:
Delete please. ..

---------- Post added at 08:52 AM ---------- Previous post was at 08:51 AM ----------

I figured it out. You have to flash the mk2 and the phills recovery through odin, than download any 4.3 rom and flash it. But before you do anything check this video out.

[Sprint Samsung Galaxy S 4 Android Development] lakemann:
Can someone tell me what I am doing wrong. I put the download tar file in oden and it does not see it or find it to flash. Never had the problem before.

Thanks
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
The file you downloaded was a zip file, extract it first, then find and open it with odin by clicking either PDA or Phone.
[Sprint Samsung Galaxy S 4 Android Development] lakemann:
That was what I was doing. I have not had a problem before but was with this one. I finally got it to work. I had to search for the file even though I had it in a folder with Odin. Thanks for the response.
[Sprint Samsung Galaxy S 4 Android Development] kerryeberrye:
You ROCK!

Thanks a mil!

Got my SG4 and ONLY rooted. Been running Sprints crappity-crap right out the box because I read everywhere that the upgrades would break root. I prefer my hotspot more than I do "updates". With TSF Shell and a few other great apps I am able to tweak my phone the way I like but my signal is crap and I'm less than a mile away from Sprint's LTE Tower @ JFK in NYC!!

Sooooo...., I downloaded and flashed this at approximately 3:09 am (est), installed OMNI ROM 4.4.2, and for the FIRST TIME SINCE GETTING THIS PHONE IN JUNE I GOT NOT ONE BUT TWO LTE BARS IN MY HOUSE!!

I am so psyched right now, you've made my December!

Then I find out OMNI has no working hotspot...., can you say DuuuuuH!

:-/ :-/ :-/ :-/ :-/ :-/

SMH/Off to another ROM

Moral of this story.....

[Sprint Samsung Galaxy S 4 Android Development] radboy:
Can use some help please. So I am on MJA with MF9 bootloader and Philz recovery and MJA Hotspot mod. Received the notification for MK2 OTA but did not download.

If I Odin MK2 will I lose Hotspot and Wifi and are there fixes?
[Sprint Samsung Galaxy S 4 Android Development] rlmiller:
No you should not. ..but just in case. .. you can always flash them again
[Sprint Samsung Galaxy S 4 Android Development] dewrust:
I have the mf9 bootloader and flashed the mk2 from this thread with no issues(don't use mobile Odin it will break media support, speaking from experience) PC Odin worked fine just include a battery pull when it reboots
[Sprint Samsung Galaxy S 4 Android Development] drewmonge:
I made the mistake of using mobile odin to flash mk2. How did you fix media support?
[Sprint Samsung Galaxy S 4 Android Development] Shoulon:
Just reflash using odin on computer.
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
Build number is the build of the currently installed system ROM, not of the modem or any part of the firmware.

This is part of the build.prop file, I've modified this in my ROM to say "ForceROM 2.3" instead of "L720VPUAMDL"

The Software Version and Baseband Version are all that matter for the Modem.
[Sprint Samsung Galaxy S 4 Android Development] xchampx13:
Ok thanks, so then yes, it does work well with Mobile Odin.
[Sprint Samsung Galaxy S 4 Android Development] Son Rise:
So All We Do Is The Download File. & Phone Into Download Mood. And Use Odin To Run It?
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
Follow the directions as they are laid out or else it won't work.
[Sprint Samsung Galaxy S 4 Android Development] STRETCH3535:
It all depends on where you are and how your specific phone does with certain modems. data speeds are not the same for everyone so just use what works best for you.

Is this the same as flashing the latest update? Sorry, confused about what exactly the modem is... :eek:

Will this work on a SPH L720 on a I9505 rom with out working voice or data? By flashing it with mobile odin pro?
[Sprint Samsung Galaxy S 4 Android Development] sggrant323:
I'm getting terrible signal indoors with the stock modem. Has anyone updated to one of these and seen improved signal? I'm a noob coming over from ATT iphone4, so I'll need to do some more reading before I'm quite ready to update, but I'm looking for solutions. I had to buy one of these zBoost network extenders to get signal in one of the locations that I am frequently at. I'd like to not need to purchase a second one of these for my house.
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
These are stock... There are no custom modems. MDL is just the newest release.

[Sprint Samsung Galaxy S 4 Android Development] sggrant323:
One is already on the way for one location. Unfortunately, that isn't an option at the other house where a couple people on my family plan live. They live way out in the boonies and their only broadband internet, (other than a Sprint 3G usb mobile broadband which doesn't exactly work without a signal), is Excede satellite internet. Since it isn't unlimited, that wouldn't work. I think I've managed to work out a solution using this:

http://www.amazon.com/gp/product/B003VOW5WI/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

It is weird. Inside their house, no signal. 20 feet north of their house, no signal. 20 feet south of their house, 5 bars of 3g. I ran the antenna outside and mounted the antenna south of the house. I buried the the cable. The signal in the room where the repeater is is now good. It isn't quite strong enough to give full signal throughout the house, but I still get 2 bars in every other room so its about 1.2mbps. Outside by the antenna the 598u can get about 2.7mbps.

The most frustrating part about it is if I go 1/4 of a mile north, or 1/4 of a mile south of the house, I get 4G in an area where 4G isn't officially even rolled out yet. This is on a backwoods country road that isn't even paved:

Too bad it's a quarter of a mile away/
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
The good part about the 4g being that close and not being rolled out is that it will probably be extended before it does officially get rolled out.
[Sprint Samsung Galaxy S 4 Android Development] BP-isMe:
Thank You for posting the modem files.

I am running Stock Rooted MDC. I assume that I can just flash the MDL modem following the post 1 instructions.

That seems to be the point of these files. Could you confirm my assumption?

Thanks...Brad
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
Correct.
[Sprint Samsung Galaxy S 4 Android Development] BP-isMe:
Thank You...

Seems to work fine...Baseband says MDL

Finally successfully flashed to MK2 while still on MF9 bootloader. Pheww, slight ordeal for me. Used Odin 3.07 on Windows 8.1. Had trouble with other Odins.

Other than that, I followed the instructions in the OP a couple times, but without success. You definitely have to do the BATTERY PULL after flashing thru Odin and it says PASS (Which the OP doesn't mention). But that's the only way I got it to work.
[Sprint Samsung Galaxy S 4 Android Development] todivefor:
That's interesting, as I installed without a battery pull. Unchecked reboot and reset and held power for about 10" (to poweroff) after passed. MK2 modem no problem.

Did the install over mja with mf9 bootloader and verified I have MK2. Anyway to get rid of the ota notification for system update downloaded?
[Sprint Samsung Galaxy S 4 Android Development] HPferoxCraft:
Long press on the notification and a little box pops up says app info I think. Click that and detick show notifications when it goes to the app manager.

Unknown maybe u can provide me with A clean original stock stock MK2 rom no mods basically a return to stock mod just in case i need to return my phone back to my carrier i would appreciate homey!!!
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
http://www.sammobile.com/firmwares/ (Type in SPH-L720) has the stock tar to use odin to go back to stock with, keep in mind this would completely wipe everything.

However, this will also install the latest bootloader as well. Meaning KNOX bootloader.
[Sprint Samsung Galaxy S 4 Android Development] prguzman1978:
Thanks homey i found it b4 your post sextape had a tar one i appreciate peace!!!
[Sprint Samsung Galaxy S 4 Android Development] 0x6A7232:
I had a problem updating to MK2 but I discovered I forgot to enter download mode from a complete powered down state, which is required.

For battery pull, I just unchecked F. Reset Time and auto reboot, which means after it says Pass in Odin, you have plenty of time to pull the battery.
[Sprint Samsung Galaxy S 4 Android Development] churchey360:
What is the difference between the two MK2 modems i noticed that there was two different downloads for it?

---------- Post added at 11:51 PM ---------- Previous post was at 11:49 PM ----------

Did you just upload them to different places so if one download link dont work then the other one would lol?
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
Just mirrors for anyone that can't get it at one or the other. Also some people have better speeds at one or the other, so I have many places to download them from.
[Sprint Samsung Galaxy S 4 Android Development] t1chaz2002:
full MK2 tar

I have seen some MK2 tar files floating around and was wondering is it safe to Odin the full MK2 tar if your already on MK2 rooted...?

To Safely remove root...
[Sprint Samsung Galaxy S 4 Android Development] PiggySmalls:
If you intend to unroot, yes. If you plan to reroot in the future, I would recommend flashing MF9, so you don't end up with the KNOX bootloader. Unless of course you already have it.
[Sprint Samsung Galaxy S 4 Android Development] t1chaz2002:
already have it...but thanks for the heads up...

do you know of any other problems I could run into..
[Sprint Samsung Galaxy S 4 Android Development] PiggySmalls:
Not that I am aware of. Ive flashed stock through ODIN before with MDL and MF9, I have never had a problem. I think though, if you've tripped the KNOX counter, it will not reset by flashing stock.
[Sprint Samsung Galaxy S 4 Android Development] t1chaz2002:
flashed team blaze stock Rom W/O Knox...so no nag was triggered...just trying to figure out a way back to stock if I need to... thanks again
[Sprint Samsung Galaxy S 4 Android Development] PiggySmalls:
In that case....maybe wait on the ODIN, get someone more knowledgeable's advise. I would hate for you to get rooted without tripping it, then trip it ODINing back. I don't know if it would happen or not....sorry.
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
Yes just Odin this

http://samsung-updates.com/device/?id=SPH-L720&details=Galaxy_S_4_Sprint

If you took the 4.3 update you have already tripped Knox, if you didn't take the OTA and manually updated modem to mk2 and then updated to 4.3 by a Knox free rom flashing the tar will not trip Knox but you will have Knox bloat now(once back on stock) and if you decide to root again you will then trip Knox
[Sprint Samsung Galaxy S 4 Android Development] PiggySmalls:
I knew someone smarter than me would chime in!
[Sprint Samsung Galaxy S 4 Android Development] t1chaz2002:
Thanks for the heads up guys...
[Sprint Samsung Galaxy S 4 Android Development] iamred:
Follow directions exactly.

I just wanted to add that the OP's flashing instructions are VERY important. Although they might seem unneeded (i.e. boot into download mode from a power off state) this proved critically important for me to get the flash to stick. I did a "hot reboot" 2-3 times and couldn't get the flash to stick. Only after following the instructions exactly did it work for me. Also, I used ODIN 3.07.

[Sprint Samsung Galaxy S 4 Android Development] Raistlin1:
We are talking about bootloaders right? If I am on MDL right now and then after I root/flash I want to move to the MK2 modem I can then go back to say an MDL modem, right? Or what this thread is calling firmware instead of modem.
[Sprint Samsung Galaxy S 4 Android Development] leaderbuilder:
Yes talking about bootloaders.

You can be on an earlier bootloader (MDC or MDL) AND ROM, and update just the Modem part of the firmware (using the Modem zip through recovery would be safest)

HOWEVER

If you take an OTA or flash the the MJA or MK2 bootloader with Knox you cannot, as yet, go back beyond MJA.

Most ROMs here have the knox bootloader stripped out and can be flashed in recovery without tripping the knox counter(bootloader). Though many do now require the MK2 modem for data services to work properly.

I'm still on the MF9 bootloader running MK2 ROMs (and the MK2 Modem). This lets me flash just about anything I want, and still have the option to PC Odin to stock MF9 if I need to warranty my device.
[Sprint Samsung Galaxy S 4 Android Development] Mistertac:
And yes you can go back and forth between modems as you like. I see someone else already explained in detail what I should have pointed out the first time. . My bad!

So... I guess this is as good of a place to ask as any. Dumb it all down for me.

Currently, I'm running Tri-Force 5.1 with non-Knox MK2 firmware. However, I'm probably going to be getting a replacement SGS4 thru warranty this week for a cracked bezel around the screen. If my replacement comes with official Knox-ed MJA or MK2, then I basically lose device warranty from Samsung when I root... Right?
