So just to confirm, the "firmware" in the OP is just the modem so I can flash the MK2 linked in the OP and that only gives me that modem and not that Bootloader? I am pretty sure that my assumption is correct just looking for a confirmation.

Thanks

For the people who got a bit out of the last guide I wrote (which has since been lost in XDA oblvion), I have written and uploaded a step-by-step guide for getting your phone rooted and tricked out. It mentions TriForce ROM, but just replace any instance of TriForce with your ROM of choice and it should be smooth sailing. I bounce back and forth between releases so I tried to make it as universal as possible (as long as the user is willing to use Philz).

Cheers!

hi

I have a Galaxy S3 Sprint (android 4.3, works perfect) but when I install CM 11, the phone runs out of signal. A modem that I can change to make it work in CM 11 (Android 4.4.2) ?

thanks:good:

anyone having problems with MK2 modem?

i tried both links above and it downloads fine and both have same checksum but i get an error when trying to flash with odin pc.

i can flash any other modem its only the mk2 file.

would like to have an option with the stock mk2 modem and stock mk2 kernel.

would be nice also.

check mk2 modem and see if it has problems for you too.

QUESTION...

I have the sprint S4 rooted w/native hotspot hack. Build is mdc android 4.2.2.

I have not updated or bothered to look for latest version of android for some time because Im soo busy with work and family!

My question is can I flash the mk2 firmware over my current version of android without issue?

Also I am looking for the latest android version stock rooted rom with native hotspot working ....if anyone could recommend a rom and possibly walk me thru flashing so I dont brick my device I would greatly appreciate it ...
[Sprint Samsung Galaxy S 4 Android Development] Mistertac:
Well right now you have a pre Knox bootloader and you're going to want to stay right there.

What you can do is flash a rom like carbon for example which happens to be 4.4 and then you can flash whatever modem you desire.

What recovery are you using?
[Sprint Samsung Galaxy S 4 Android Development] byg.nick:
Just upgraded from MF9 to MK2 firmware using the method described in the OP. Working flawlessly. I remember you from the EVO 3d forums, serious genius over there too... Unknownforce, you sir, are the man.

---------- Post added at 08:48 AM ---------- Previous post was at 08:26 AM ----------

[MENTION=2209683]PHIL2577[/MENTION]: I just updated from MF9 to MK2. Here's what I did:

Flashed this (odexed) stock MK2 ROM through custom recovery: http://xdaforums.com/showthread.php?t=2586586 (I believe that you could pick any custom 4.3+ ROM, but the one I listed is basically completely stock minus KNOX which you don't want anyway.)

Booted into rom, setup and let it run for a few minutes to verify that eveything worked (except for WiFi, as I hand't updated the Firmware yet)

powered the device completely off, then followed the instructions posted by [MENTION=1354510]Unknownforce[/MENTION] in the OP of this thread and updated my firmware using Odin (directions here: http://xdaforums.com/showpost.php?p=42954144&postcount=1)

powered phone off and then back on using directions in OP, confirmed that WiFi, cell, and data all worked.

rebooted into recovery and flashed this native hotspot hack http://xdaforums.com/showpost.php?p=48590490&postcount=337

powered phone off, restarted, confirmed that Native Hotspot was working, and... Viola.

I am using Philz recovery now, as TWRP was having an issue opening the ZIP for the rom.... not sure why, but I believe that you *Should* be able to use either recovery... hopefully someone with more knowledge on this part could steer you in the right direction.

I can honestly say that with this setup, my phone is running faster/smoother/more stable than ever before, although I keep it pretty close to stock and haven't even been off of a TW Rom. Good luck!

Thank you so much btw this is exactly what I was looking for !! A walk-thru and an updated stock-ish rom that outperforms a stock bloated sprint rom

I probably should mention that I got this S4 about 2 to 3 months ago via a warranty claim as I broke my orginal S4 not sure if this matters but this knox bootloader mentioned kinda worries me is there any way to check my bootloader?
[Sprint Samsung Galaxy S 4 Android Development] byg.nick:
I'm not sure how to check just the bootloader, but if you haven't followed the process to update just your firmware, you should be able to look in Settings>More>About Device>Baseband version... if you are MF9 or before, you don't have knox. I know there's another way to show each item of your firmware, but I'm not entirely sure how to get you there...
[Sprint Samsung Galaxy S 4 Android Development] zsgoin:
Bootloader Version

To check your bootloader version type *#1234# in the stock dialer and it should say the version an the AP line
[Sprint Samsung Galaxy S 4 Android Development] PHIL2577:
I tried this method....MDC was the last 3 letters in the ap line but it did something and requested su permission after granting su permission a screen flashed rather rapidly all I could read was knox disabler and then it said knox disabled i have a ss ill try to upload :confused:
[Sprint Samsung Galaxy S 4 Android Development] PHIL2577:
sorry guys for the double post couldnt find the ss from my laptop so I uploaded from my phone and thank you all again im guessing I would have already screwed up this phone if not for your help!

Does this mean im good to flash the rom/modem of my choice now? I am very much lost at this point

(Edited) You can't break KNOX on a permissive KNOX bootloader which MDC is.

Why would it say knox was disabled? If I remember correctly this phone was on android 4.3 when I got it thru a warranty claim,at the time there was no hotspot hack for 4.3 so i reverted to 4.2.2 I used a pre-rooted stock sprint rom via odin.guys im sorry for all the hassle here just tryin to get an updated version and not have a brick lol.I just purchased the zerolemon extended life battery and a pretty nice zerolemon case which has renewed my interest in my s4 .THANK YOU ALL !!!:good:
[Sprint Samsung Galaxy S 4 Android Development] egingell:
As far as i know, breaking KNOX won't brick your phone, but it does void Samsung's warrantee and changes your splash screen.

[Sprint Samsung Galaxy S 4 Android Development] zsgoin:
To explain the SuperSU KNOX disabled the way I understand it the KNOX applications were present in the stock roms but KNOX was absent from the bootloader (MF9 and before). SuperSU detected the applications and disabled them. KNOX was the end goal from the beginning but its release was delayed until the MJA update so fragments of it existed pre MJA update.
[Sprint Samsung Galaxy S 4 Android Development] Mistertac:
Exactly, breaking /tripping Knox won't brick your phone. It just shows the Knox Warranty bit at 0x1 and then depending on who you're talking to you no longer have warranty.

Was the firmware file supposed to include Baseband? Can't remember if that's part of bootloader or something separate. (Flashed the MK2 from the OP but I'm still on MF9 Baseband)
[Sprint Samsung Galaxy S 4 Android Development] swiggs98:
Most common cause from what I can tell is rebooting into download mode vice power down. If that isn't it, there are several others in this thread that have discussed this and shared their resolution.
[Sprint Samsung Galaxy S 4 Android Development] Thistleknot:
I can confirm that this was the issue I was having. Booting into bootloader from a powered off device resolved my issue
[Sprint Samsung Galaxy S 4 Android Development] xfullmetal17:
Figured it out in the end, once I flashed CM11 the Baseband took as well.

MK2 to MDC downgrade Moden only

Hi,

Just a silly question that I am currently on MK2 OTA update want to use this phone outside of US, cant ask Sprint to unlock as it was purchased from Craigslist.

Can I downgrade from MK2 modem to MDC and unlock. After unlocking flash it back to MK2. I suppose it will break Knox but I am not eligible for warranty so as far as phone works OK I have no issues with knox as I can freeze the two apps checking knox.

I hope someone could guide me out of the situation.

Thank You
[Sprint Samsung Galaxy S 4 Android Development] egingell:
Why can't you ask Sprint? Unless it's a bad ESN and you've flashed it to Verizon, I don't see them having a problem with where you bought it from. Then again, I've never done it or even tried.

modem push through Heimdall

WTF?? I finally got mk2 modem on my phone, but they sure don't make it easy. Apparently, I made the "rookie" mistake of thinking rebooting to download mode from the menu would actually work. Jeez, whatever. Then I had to go through 3 different usb cables and 2 usb ports and 10 attempts before the download would complete successfully. The download procedure is so flakey on the gs4, I'm biting my nails every time I do this. My old fascinate never had this problem. Oh well, another crisis narrowly averted until next time...

---------- Post added at 01:56 PM ---------- Previous post was at 01:47 PM ----------

Its just modem firmware correct? No bootloader. I was thinking if I tried another mk2 modem this may fix. Or if you know of a mja or mk2 flashable wifi fix?
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
The MJA package does not have the bootloader chain, the MF9 and previous ones I think I was still including the bootloader in, which will fail if you try to flash them. I can make new packages without the bootloader chain in them if I get some time here soon.
[Sprint Samsung Galaxy S 4 Android Development] Goat1378:
Thanks man thats great if you want to but you dnt have to do that. I know you developers have lives with alot of s#@t on your plate. The guys rom that im running is probably sick of me im always asking s#@t lol but at this point I dont think its the rom. I've flashed other roms with the same out come. Poor wifi too slow message. Driving me f#@ken crazy. But any help will be very much appreciated. :)
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
You can get rid of the message by disabling the Auto Network Switch in the Advanced Wi-Fi settings.
[Sprint Samsung Galaxy S 4 Android Development] Goat1378:
But that don't fix the problem will it? The message doesn't bother me as much as not having the wifi. lol but yes i will do that thank you!
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
It most definitely will not fix not having Wi-Fi. Modems can have an effect on it, but in all honesty, our phones simply have terrible radio hardware, both LTE and Wi-Fi. I don't know that there's much you'll be able to do to fix it. It's just a fault of certain Sprint models. The other carriers don't seem to have these problems, and as you might or might not know, an S4 is not an S4 is not an S4... they are all different, we seem to get the short end of the stick when it comes to radio hardware.
[Sprint Samsung Galaxy S 4 Android Development] cruise350:
This would help people wanting to unlock their SIM card after updating to mja or mk2. This way they could just install the MDC modem, perform the unlock procedures and then go back to the mk2 modem.
[Sprint Samsung Galaxy S 4 Android Development] Goat1378:
Well that sir.. Sucks a big bumpy one! Lol I know it may not do much but im willing to give it a shot I know the phone is capable of getting good wifi cuz I had it before the switch to mja and so on. So its got to be there somewhere. And thank you for taking the time to talk with me that's really cool of you guys that take time out after the work you guys put in to help or try to help us guys that need it.
[Sprint Samsung Galaxy S 4 Android Development] desiwizard:
Thank You for the suggestion, one more thing if I unlock buy downgrading modem only to MDC and then flash complete MK2 stock rom via odin to clear out any errors, or any time in future if I flash a custom rom will I be still unlocked?

im trying to get back to official stock with what i have installed

im unrooted after telling supersu "full unroot"

i have twrp 2.6.3.1 installed and i need the "stock mja recovery" in md5 format if anyone can tell me where to find it.

i was hoping in this thread but i see no full firmwares for mja

i see a "recovery.img" in the mja stock official tar.md5 i have but i know there has to be a stock mja recovery somewhere right?

is the recovery the bootloader?

do i need the stock bootloader too?

thanks
[Sprint Samsung Galaxy S 4 Android Development] Goat1378:
Wow you really did it! The bootloader not inclued. Is that what I was asking about when I was questioning wifi fixes? Is that what I was looking for?
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
The only way you'll get it to show Official again is to re-flash the full Stock Tar, and possibly twice.

If you're already on the knox bootloader, then just use the MJA tar, if not then I suggest sticking with MF9, so no knox bootloader.
[Sprint Samsung Galaxy S 4 Android Development] en11gma:
not ture

what i wouldnt up doing was using cf-auto-root to get root

do all my stuff i needed to do with*#0011# and ##3424#

i then did a "factory data reset" from settings

that put me back to stock official mja

i believe cf-auto-root uses the same stock recovery or something.

somehow im showing "official" in settings about phone status

[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
This post isn't related to kernels at all. This is strictly Modem firmware and bootloader.

If you're on a ROM that is based on MK2, and you're running MK2 Modem, then a stock MK2 kernel should work. They all have to match for it to work. Otherwise a custom kernel and possibly the WiFi fix is necessary for it to work.
[Sprint Samsung Galaxy S 4 Android Development] xfullmetal17:
Huh, for some reason I can't seem to get this to stick... I didn't have an issue going from MDL to MF9 in Cyanogenmod 10.2, but now with 11 I can't do the baseband update from MF9 to MK2. Unless something in Cyanogenmod 11 is overriding the MK2 baseband.

Power off

Boot into download mode while unplugged

Attach phone, load the MK2 modem into PDA

Flash modem, leaving auto-reboot and F. Reset Time unchecked

After it succeeds, power off by holding Power for 10 seconds (I have a case on my phone and it's a bit of a pain to take off)

Boot back into CyanogenMod.

Using Odin 3.07

Those steps worked for the MJA update

edit: Figured it out, for whatever reason I actually *did* have to physically pull the battery, plus a trip into recovery for a cache wipe.

You also have to use an MK2 kernel for the wifi to work when you are using the MK2 modem. Look in the original development section for an MK2 compatible kernel or flash an MK2 based rom that includes the stock or custom kernel.
