flashing roms on MJA

I've been searching around as much as possible but the XDA search function seems to be broken because no matter what I put in the search field it returns no results.
I updated my S4 to the latest OTA and am now on MJA. I rooted it and installed TWRP. Reading all this stuff about MJA and Knox has me worried I might screw something up so I want to make sure before I proceed with flashing roms. Can I flash roms now without worrying? Can I flash 4.4 and not brick my phone? I don't really care about tripping counters or voiding warranties.

Well first off, I don't think TWRP is playing nice with the MJA update at the moment so I would recommend using Philz Touch CWM recovery, Then just head on over to the rom threads,and check them out to see which one would best suit your needs. I myself am running Stock Rooted but it's just my personal preference..:thumbup:

Thankyou, there isn't much concise info on the MJA update and what we can and cannot do with it.

[Q] Please help...

So here's what happened. Unrooted my s4 to get the 4.3 update. Don't care about warranty issues so then I rooted again and installed CWM recovery and then wireless teather hack. After restart it just sticks on sprint screen. Being hasty and stupid I did not back up stock firmware before I installed the teather hack. Is there a way to get the stock rom back on this rooted phone. So far all I can find is the stock firmware to keep the former bootloader. Will this tar file work for me as well? Help greatly appreciated.

If you want to download the stock MJA you can go here: http://forum.xda-developers.com/showthread.php?p=47359331 Then you can re root and then use Philz Touch CWM. You should be good to go..

[Q] How Do I Get To MF9 From MK2? Sprint S4

So i updated to MK2 firmware this morning from OTA with my phone running Stock 4.3 MJA. I now realize there's a problem, as it WILL NOT LET ME TURN WI-FI ON. Each time I try, it force switches it off and brings up a KNOX notification saying that the attempt has been blocked. Can anyone tell me if there's a way to get back to the older firmware such as MF9 from MK2 right now? Also, I tried going back to MDC using Odin 3.07 and Odin 1.85, neither worked. Please help.

You can't.. Once your on MJA that's where you are stuck although I believe you can go from MK2 to MJA but that's about it. Otherwise there is no downgrading to any previous firmwares. Please read through the threads... All answers are here if you read...

Hmmmm...I'm now on MK2...just hoping there's some way to get back to MJA even. Also, another thing has caught my eye when the phone turned on. Music force closes and sound doesnt work one bit. Is there any way to factory restore the device at the moment with/ without using Odin? Like an MK2 factory reset file?

I tried the link, although their servers are down so I'm unable to download anything from that site. Is the file I have to download a large 1.53 GB file? Also, Sound doesnt work and Music force closes when i try to use it. Do you know of a way to hibernate or kill any knox related processes in the system so that it stops turning my Wifi off?

Negamann WonderROM has a working r26 ROM that he just finished building today with verified MK2 kernel that works with wifi.

If he didn't take the ota he could of went back. Is that correct? Taking the ota locks the bootloader. If he updated with Odin and Philz recovery he could of keep the mf9 bootloader allowing him to down grade
Love the 90s good times

Waiting for the OP to post back if he was successful in downgrading MK2 to MJA by running the full MJA tar file. I know you can't go back farther than MJA but hoping we can at least downgrade back to MJA if we need to after a failed upgrade or bad ota.

I have downgraded mk2 to mja working fine no Knox flags tripped (still at 0×0). 100% stock everything.

I actually took the OTA from MJA to MK2. thought it would be a better update since it said that before i installed it. Instead, it causes more bugs on my phone, where i cant use Wifi and even play Music, let alone the fact that no sound plays at all on anything and i can't make a call...as the Phone app freezes when i try to make a call.

Please tell me what files you used. because at this point, I just wanna watch a simple Youtube video and call my friends! All of my data (contacts, pics, music) is already backed up on my computer. I don't have Root and i tripped the knox flag once so it says 0x1 which pissed me off

Hey thanks for being great helpers with helping me and my phone troubles...apparently my phone works again! Knox is not blocking my wifi and my sound and Music and Calls and everything is working! I'll post a new thread if any problems arise with this update. But to be honest...stick with MJA guys. Don't go through the same trouble i went through. Too much stress to handle when u can't make a single call or play your fave song or even connect to your beloved Wifi hotspot!

I can confirm that you can downgrade from mk2 to mja as I have done it. They process want difficult at all. Going that OP can get it going and it works out for them.

Ok one question...when u downgraded, where did u find the file? And did the file wipe your data?

http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy S4 (SPH-L720)/Stock ROMs/MJA
I used this. It did wipe everything from my phone. I just made sure to back up everything I wanted to save on my sd card using super backup. You can find that on the play store.

I had the same issue with WiFi not working and get the message. (For details: On a Stock rooted S4, Updated the Security policy and then flashed the MK2 modem).
I went to: http://forum.xda-developers.com/showthread.php?p=42954149 and followed the exact instructions to go back to MJA. It worked. I didn't lose anything. Only a ~26mb download.
Hope this helps.

I had the exact same problem as the OP with wifi and KNOX notifications upon toggling wifi. This had to do with a bad update which I believe was a result of rooting my phone. Something is weird with recovery after rooting the phone with cf autoroot as it no longer looks like the stock MJA recovery. So when I manually installed the MK2 update using what I believed was the stock recovery, I experienced serious issues such as what the OP described.
In any case, I used ODIN to flash the MJA tar which restored everything back to normal. Then I used the stock recovery to apply the update zip file and everything went without a problem. Then I flashed cf autoroot with ODIN and again, the recovery looks different from the stock MJA and MK2 recovery, but everything works fine. I did not do a data wipe during any step of the process and have seen no ill effects so far.
So the take home message is, if you rooted the phone ODIN stock MJA or MK2 if it becomes available before applying any future updates manually. Or ODIN a stock recovery file for your current ROM if one is available. KNOX has nothing to do with this. I disabled KNOX and still could not turn on wifi.

What if you have mf9 baseband? Can i down grade from mk2 to mf9 and if so how do I do this?

After going to Sammobile and finding my newest firmware (I realized it was MK5), I flashed it used ODIN and all is well again. Thanks to the people who assisted me as well as they could

So, yesterday I receieved my new S4 and wanted to install the Google Play Edition rom, well after I flashed the ROM and following all the steps, my phone will no longer boot. Any time I try to flash my "stock" firmware, Odin says "Fail! (Auth)" I don't even know which firmware to use because there is so many and I'm freaking out because everything I seem to be trying is failing. A little help would be appreciated...

Sounds like you're trying to flash a firmware other than MJA or MK2. You are most likely on the latest firmware and trying to flash a previous one.Look for an MJA or MK2 and you should be good to go.

Hey thanks for responding. I have been trying to flash the MK2 firmware over and over again using the newest Odin. I have also gottent he phone working again by loading a stock rom off external_sd, but now my wifi isn't working. I know that's an issue with the Modem not being updated, correct? Everytime I attempt to install the MX2 firmware it FAIL! (Auth). The only thing Odin seems to want to install is custom recoveries. Gladly, I am not bricked, but I did stay home from my first class today to fix my phone Any idea on getting the WiFi working?
ROM I Installed: http://forum.xda-developers.com/showthread.php?t=2586586
(Deodexed)
Unfortunately, I tripped the KNOX Flag, but I'm not worried about my warranty currently because I do know what I'm doing for the most part, except this is my first time rooting/unlocking a phone instead of a tablet so it's much more intricate.
Thanks

Although I'm still on MJA I've heard of people having success by just flashing the MK2 modem. Just look for the modem and flash it with Odin.

Dude what I'm saying is I try to flash the MK2 Modem file, but Odin just gives me a "FAIL! (Auth)" error every time.
I also figured out that my phone and Kies is reporting the following:
PDA: MK2
Phone: MK5
CSC: MK2
Is MK5 even a thing???? I'm so confused
UPDATE:
So I didn't realize that I had the SPH-720T so I was trying to flash the wrong firmware, and when I installed the custom rom, my firmwares were mismatched; therefore causing the errors. It's flashing the MX5 PDA file successfully as we speak. I will update further on what happens.
UPDATE 2:
The Firmware installed as it should have and my wifi is indeed working again. Phone is clearly functioning and everything seems to be in order. Now I will never touch my phone ever again until I learn more about the ROMs and compatibility.

Hey I know the thread is dead, but When you installed the new Modem did you end up having to wipe the current Rom you installed? I was just curious if you got it running on your custom rom with the new modem. Figured Id ask while waiting for the dinosaur download speed. Thanks again!

I haven't tried because that file isn't the modem its the whole 4.3 rom and boot loader. that's why it's 2.1 GB. I ended up bricking my phone until I found the MX5 firmware. so I have no clue. I'm done messing with Roms until developers start working on the triband version of the S4
