Cant go back to stock kernell after using kt

Hi, I installed the kt kernell. the only reason why I installed it was so i culd get fas charging support, so I could charge my phone while using it with my appradio. I never used the overclocking part, or any other feature in that kernell. After a while I tried to update to MF9, follow the official mf9 thread, (flash noobl zip, flash kernel file and then flash rom file.) It all seemed to work, but in the phone info screen everything shows the right version exceot the kernell part. i have attached a screenshot. After that i tried downgrading to mdkl, and same thing. kernell version still shows the same thing. any help will appreciated. thanks

That kernel you are on is stock

Is that what the kernel info is supposed to say? I ask because while i Had the MF9 stock Rom it said the exact same thing., and I figured It should said MDL or MF9 somewhere in it.

yep its what it is supposed to say, doesn't specifically say MDL or MF9 in it.

thanks, i thought I did something wrong and screwed my phone up. I appreciate your time.

Baseband has to do with MDL and MF9. Kernel is different. While you still need to know if your baseband is MDL or MF9 for choosing a kernel, the kernel itself isn't really dependant on the baseband.

so only software, baseband, and build should match, am I correct?

The baseband and build should (if you're on stock, at least)
I don't see the software anywhere (sorry, I'm on CM, not stock)

How to update baseband/modem

I've been flashing ROMs since I got my phone many months ago but, despite flashing CM10.2, Omega 13, Slimbean build 2, etc... it seems that I still have the MDC baseband.
How can I find and flash an updated modem?
I ask because I don't get 4G or LTE on slimbean or Omega and others indicate that they did. I am hoping that an updated baseband will get them working.

Odin back to mdc unrooted and catch the otas to mf9 then use cf auto root to root, do a nandroid backup and flash whatever rom ya want. Thats what id do. I get lte on slim and all aosp roms..

Actually, just odin the full mf9 tar file from sammobile and you won't have to do the OTA crap.

So I Odin'd the MF9 baseband, that didnt help.
Then I Odin'd the entire MF9 ROM - THAT STILL DIDN'T HELP!
Even in stock MF9 I didnt get 4G. I was going to bring it into a sprint store but on a hunch i went to Update PRL (that didnt help) and then
Update Profile - Voila!
So, if anyone else has this problem, flash back to stock and do an "Update Profile."
I have since flashed back to SlimBean and retained my 4G. Still have no idea how I lost it but I'm glad it's back.

here you go bro (link below), Hope this help's it did for me, cheers

Question is HOW did you 'get it'?
What is your current ROM and how did you get/install that?

I got the modem from the tri force rom, i was on a mf9 stock rom, it got changed to mk2. My current rom is slim bean 4.3 2.2 final, and i got it from the official site

Try going to a stock MK2 ROM to see if that fixes your issue.

You could not have gotten the modem from a ROM. It is not included in any of them. If you are flashing some 4.3 ROMs without using Odin to update the modem, you could run into issues.

Honestly, i tried using odin to update my modem but everytime it'd fail when i tried, so i gave up, but when i downloaded the tri force rom that's based on mk2 for some odd reason it said my baseband was now mk2, so i thought it did it automatically, but now no matter what rom i go to, whether it be jelly bean or kitkat based ones the phone apk lags, freezes up, and messes up everytime

And what frostedunit said is true also. Modems must be flashed via Odin in download mode.

now my issue is wifi not working ;( i'm on the rom "stock(ish) v01"

You must be on the MK2 modem for Wifi to work on that ROM. Redownload the modem .tar from Unknownforce's thread in development and Odin it in. Sometimes it takes a few tries for it to stick. Just make sure to run Odin as administrator and put the modem .tar in the phone slot.

{Solved}Please help me!!!...I tried to update to kitkat.

I tried to update my sph l720 to unknownforce kitkat rom ....BUT
after i flashed the NAE modem and then flash the ROM after wipe...wipe...wipe....format...format ...format
My wifi and 3g data are OK....working.
but I can not make or receive any calls......Just i can receive SMS?
So what is the problem?
please help me
The Solution:
1)Flash mf9 stock odin file.
2)dial the code ##786# to return to sprint defaults.
3) update one by one...mf9>>mja>>mk2 then flash the NAE .
4) Flash the phone again to my local carrier using DFS.
Now all things are working great.

Have you updated profile and prl? What recovery did you flash with. What where you on prior to???

That means your firmware has already been updated to a version newer than MF9. Once you have gone to 4.3 (MJA or MK2) you can't go backwards to 4.2.2 (MF9). IF you have already upgraded to Kit Kat 4.4 (NAE) then you can't go backwards at all.

Thanks for your help cruise350. The knowledge of MF9, MJA, MK2, NAE helped me alot. Finally it's working now perfectly. I am running hellkat rom (NAE) now.

@dreamii, I'm confused? I am running the MK2 along side KK without issues. Did you have problems with the baseband? Did you upgrade to NAE baseband to get your calls to come in and is that what solved your problems?
Just trying to understand where it went wrong? LoL!

What I was running MK2 and hellkat 4.4 rom, I couldn't get any outgoing or incoming calls. And there is this sound issue also. The speakers, the headphone jack wasn't working. After I upgraded to NAE, it worked smoothly. In my case, combo of KK 4.4 and MK2 firmware was giving me trouble.
So this is what I did.
1. NAE stock 4.4 rom
2. NAE firmware flash with Odin 3.07
3. Wipe clean stock rom/cache
4. Install hellkat rom
Works like a charm now. :good::good::good:

Coud'nt you have just flashed the NAE modem then update PRL/Profile? Most times that should fix it.

I did try other KK Roms when I was at MK2 + some JB roms also. Same issue. I tried stock unrooted KK rom, TriForce JB rom, Omni Rom, Avatar KK rom. All had same issue.
I didn't thought of just flashing NAE and updating PRL/Profile... huh.. Should have done that so it save some times for me.

FYI, I just rooted a S4 with the MF9 BL and flashed LS KK with no issues, everything works.

[Q] OTA 4.4 back to 4.3

Can someone help me take my S4 back to 4.3? I got the OTA update for 4.4 yesterday morning and have had nothing but problems. Terrible battery life (40% down in 3 hours with little to no use) WiFi wont turn on thanks to this piece of junk Knox software. So before I dump Samsung completely for a Moto X or Nexus, can someone help me downgrade from 4.4 back to 4.3 where I had no problems?

Were you totally stock before the OTA? If you still have warranty left, I would bring it in to a Sprint store and *****.
If not, you can try one of 2 things. 1) flash the NAE tar file using odin to see if that fixes your issues or 2) flash the MK2 tar file to bring you back to 4.3

I went Cyanogen at one point, didn't like it, and flashed back to stock. When the OTA hit I was rooted but had made no changes from stock, not even an uninstall of a Samsung app. I am backing things up now to flash the NAE again, but I want a version without this Knox garbage in it. Is there such thing?
I read that you can't flash back with Odin from 4.4 to 4.3 so I don't know how to do option 2 at this point.

You're correct with not being able to go back to mk2 4.3 via Odin.

Yeah, I think you are right. Can't go back to 4.3 once you have the 4.4 bootloader, my bad. I wonder if you should do a factory reset to see if that clears up your issues.

Is there some other way of downgrading? What about going back to Cyanogen's full release?

Well that sucks that you can't go back to 4.3

I had the same issues when I updated and was kinda pissed at it to but a factory reset and it been running way better ever since and I'm rooted with xposed installed and no complaints

I believe once KNOX Bootloader has been installed, your stuck with it. No going back.
But honestly, if you root 4.4, your gonna void KNOX.

You can still have all that. KNOX is just the warrantly flag I have KNOX on mine, but I still have rooted and flashed other roms.

You're saying your bootloader went back to MK2 after this? Didn't think that was possible. I've had nothing but stupid little issues myself after using Odin to flash the phone to NAE. I've done factory resets... Completely wiped the phone in Philz. Tried KToonsez kernel as well and stock NAE just sux! I'll probably just flash Liquid Smooth back on it, was only trying to stick with stock NAE for stability and camera , that phone is my girls and she doesn't have the patience for all the bugs that come with custom Roms lol
Anyways just want to confirm that with you. Thanks

I don't know if that is possible for those of us rocking triband. Obviously we cannot use the Mk2 modem or rom. In any event, I upgraded to 4.4.2 on my new L720T and regretted it, but now I'v" managed to install twrp and rooted it and the rom settled down after a few days. At first, horrible battery use but now its amazing. My battery reads 75 percent after 14 hours and that's quite good enough. The only issue I still face is the SD card thing, but that only seems to apply third party software as I can move files directly from internal to external memory using the stock files app that comes with android.

i dont know about triband. i dont have one and im not going to pretend im a smart dev because thats also not true.. i HAVE ODIN 4.4.2 THEN turned around and ODIN 4.3 due to something i didnt like...im not sure if it changes the bootloader or not, i dont even check. i have only tried this with mk2 to nae.. when i purchesed my device it came with mk2 so i have never tinkerd with the other bootloaders. if you have something other then mk2 id ask a dev befor doing anything. like i said it works for me as long as i flash the modem FIRST that corrisponds to the build. ( mk2 or nae )...and in some cases if the wifi is borked on nae, iv had to flash the modem again after instalation of the rom.. i cant explain why any of this happens....

Lol I know what you mean... Sometimes things just seem to work or they don't.
But that's interesting you can go back to mk2 after being on nae. I figured that was not possible. But if you didn't get any fails in Odin while downgrading that's great. Maybe I'll get ballsy and try this later.

Is there a stock 4.4 Rom out there I can try, preferably one without Knox? Sprint has recommended that I unroot, that they have a tech bulletin where rooted phones have wifi, and other issues.
