I will be giving it a shot. Currently downloading BlackBox NB8. Plan is to Odin MK2 AP, flash the ROM on newly created slot 1 along with the ATT Modules, Odin the NB1 files, and boot. Success = both ROMs are bootable. Total fail = both ROMs are lost and will have to start from scratch. Will post results.

---------- Post added at 12:13 PM ---------- Previous post was at 11:30 AM ----------

NO GO. The ROM would not boot of ROM slot 1 - black screen after Samsung logo. However, stock slot remained unaffected and booted the previous ROM with no issues. I am thinking that the NB1 modules we patch may only impact the stock slot and not apply to other slots?
[AT&T Samsung Galaxy S 4 General] DeadlySin9:
Neither the modules nor the TARs would apply to only the stock slot as long as you flash correctly. The issue is probably that Safestrap can't mount the stock slot when it's 4.4.2. This isn't an issue on the stock slot as the bootloader will go to it normally, but in the case of the ROM slots, it can't correctly mount the image that it creates for the slot and therefore has no system to boot.
[AT&T Samsung Galaxy S 4 General] rebel1699:
Not only that, but ss uses a secondary init for rom slots. Odds are, it would not be compatible with 4.4.2 anyways. I plan on asking hashcode if he minds if i make a modified ss that will be installed after 4.4.2 upgrade, that wont require reflashing the mk2 boot.img to install other 4.4.2 roms or add ons.

[AT&T Samsung Galaxy S 4 General] dave5777:
Are you AT&T SGH-I337? If you're not than it's not for you. Official AT&T KitKat is NB1. I think NC1 is for SGH-I337M.
[AT&T Samsung Galaxy S 4 General] DeadlySin9:
This is for NB1, the AT&T I337 update. NC1 is the I337m update and the software is not cross compatible.

[AT&T Samsung Galaxy S 4 General] NighthawkXL:
True, and yes I think your partially right when saying that MK2 and NB1 likely share some files together. But it doesn't explain how we get a fully working MK2 build on the NB1 bootloader and kernel. Generally Samsung changes the certificates per update, to my recollection this method "should" have ended up with a unauthorized system error. Granted, I could be complete wrong though...
[AT&T Samsung Galaxy S 4 General] ted77usa:
When u got unauthorized system error then u need to flash jlfte-att-16GB. Pit files to get u back to NB1 and then flash AP and CP files to downgrade.... I'll would add that PIT files tonight after work.....I thought I attached that PIT files last night.....:D:D

Thanks for all the help today guys...
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
Don't need to post it on my account I wasn't trying to downgrade I'm still on MK2 for daily driver, and MF3 for my spare phone. Just trying to coordinate information back and forth in hopes of a breakthrough. Though, I'm not overly optimistic on this method being anything more then a fluke.

Speaking of PIT files, might want to put the 32GB one up if it's available as well.
[AT&T Samsung Galaxy S 4 General] rebel1699:
Luckilly, I have a 16 pit file handy. I pulled one from heimdall a while back.
[AT&T Samsung Galaxy S 4 General] Surge1223:
I dont think your downgrading aboot. Here, let's find out. Run the below commands on both MK2 and NB1. This will also tell us what the counter is set to as well.

su
mount -o remount,rw /system
cat /proc/version
strings ./dev/block/platform/msm_sdcc.1/by-name/aboot |grep _ID

Also if you want to extract your stock signed PIT then open terminal emulator and type the following commands:

su
dd if=/dev/block/mmcblk0 of=/sdcard/1337-GS4.pit bs=8 count=580 skip=2176
[AT&T Samsung Galaxy S 4 General] rebel1699:
Give me just a bit. I am going to odin to stock mk2, then update to 4.4 and put all things to a full test. If you have anymore things you would like checked out, list them here. Hopefully we find some good surprises. Worth a try. This community has been great to me for 6 years. Time to give back.
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
Yeah, I don't think we're touching anything in the bootloader at all in this method as the baseband remains at NB1 while the build goes back to MK2. I can pull the strings from my MK2 phone in a little while.

Here's what the NB1 counter is set to according to jeboo's post about it on another thread.

[AT&T Samsung Galaxy S 4 General] Surge1223:
Yep, that proves it. The NB1 KitKat OTA increments the counter in aboot from 4 to 5.

People taking this update won't be able to downgrade after. Proceed at yout own risk
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
That's just it... while they aren't downgrading the bootloader using the method here, they are successfully getting the 4.3 MK2 build to work on the NB1 baseband.

So this can restore back to mk2 completely including the bootloader and from restored mk2, i can install nb1 rom. Am i right?
[AT&T Samsung Galaxy S 4 General] rebel1699:
If you have the nb1 bootloader, the bootloader itself cannot be downgraded. Only the system and boot.img can be downgraded. But using this method will allow you to downgrade those two things to mk2, root and install safestrap. And then, yes, you can install custom nb1 rooted roms.
[AT&T Samsung Galaxy S 4 General] j_harris15:
I noticed the .tar file says "16G" at the end - will this method also work with the 32GB model?

Thanks,

[AT&T Samsung Galaxy S 4 General] rebel1699:
The .tar does not say 16G. The pit file does. Dont use the pit, just in case.
[AT&T Samsung Galaxy S 4 General] DeadlySin9:
For the record, it works just fine. However, the only time you need it really is when flashing individual partitions through heimdall, which is not necessary and not recommended for any of this. If you majorly borked your device somehow then it may help, but otherwise it makes no difference usually.

[AT&T Samsung Galaxy S 4 General] grneyez:
Yes, just found out that was the issue, thanks for the reply. I have one question regarding the (universal init.d toggle) does this app need to be used to regain wifi every time you reboot? or is it supposed to retain the settings after reboot? I find that every time I reboot I have to use the app to get wifi back again.
[AT&T Samsung Galaxy S 4 General] dave5777:
Once you set it up it will automatically load on boot but it might take a minute after your phone boots up until it turns wifi on. On a side note if you just want rooted stock use muniz_ri's NB1 stock root method. I flashed it the other day and ditched SS for now. No issues 100% rooted stock :)
[AT&T Samsung Galaxy S 4 General] Maribou:
Nice.. if I get the time this weekend I'll try to make a flashable zip for the MK2 downgrade. That way if you want to faux downgrade to MK2 from NB1, you won't have to manually enable Wi-Fi.
[AT&T Samsung Galaxy S 4 General] grneyez:
I waited about 4 minutes after reboot but it does not kick in on it's own. I have to manually have to reset nbi wififix and hit the play button to get wifi to turn on again. It is a minor inconvenience, but I cant get it to lock on after reboot. Anyway, I;m running Goldeneye 21 and it's running like butter.Sure wish I could get the wifi turning on after reboot on its own,.

I337UCUFNB1 100% Stock, Rooted SS Flashable ROM

OK, I did a little more research.....this person (http://xdaforums.com/showpost.php?p=51254864&postcount=213) was on the MK2 bootloader and unknowingly flashed the NB1 bootloader which solved the lockscreen problem but he is now stuck on the NB1 bootloader and will be unable to go back to factory stock MK2.

Since you have already flashed all NB1 partitions on your device, except for the NB1 bootloader, and still have the lockscreen issue; it seems that the only way for MK2 users to solve the lockscreen issue is to upgrade their bootloader to NB1.

Thank you for helping me test.

Can still flash Factory MK2

Hello, I am no developer or computer gig - normal word excel computer user and I don't understand technical stuff bootloader and things like that. But just read here saying that I cannot go back to factory stock MK2. Well it seems that I still can. I flashed file I337MK2Boot.tar.md5 on BL thingie in download mode using odin and after that I flashed the MK2 stock root posted in other forum as "All in one.tar.md5" or so and my S4 is up on MK2 as well. I don't know if that's a surprise or normal behavior but since you guru's helped me - thought to share this information with you..

But I still cannot teether on this pre-rooted stock 4.4.2. Hope someone here helps me to fix the teether issue.

If you want to do this and go back to MK2 Factory stock : Here are my steps:

1) When I was on rooted Factory Stock MK2 - I installed SS

2) Went in SS and did "BackUp"

3) Now followed the steps - wipe, clean, install 4.4.2 pre-rooted stock in stock slot.

4) Now flashed the 3 files as I said earlier in download mode to resolved lock screen issue.

5) Now booted the device - checked all is well except tethering does not work...

6) Then read that I cannot go back but my tethering only works in 4.3 so I rebooted in ss

7) Tried to restore the backup of mk2 I took in step 2

8) Now restore failed and it said cannot wipe/mount /system...

9) Now I it reboot and my god got message "firmware upgrade failed bla bla.....go to Kies and do emergency firmware recovery" (I got scared)

10) Then tried kies - it does not detect the phone

11) So I read online somewhere that I need to flash I337MK2Boot.tar.md5 in BL slot using ODIN - so I did that

12) Bingo yeah phone started in ss

13) Went to Restore and restored the backup sucessfully that I made in step 2

14) Now I again went into download odin mode

15) AND BIG BINGO - FLASHED PRE-ROOTED STOCK MK2 - ALL IN ONE TAR - ALL SUCCESS

16) REBOOTED THE PHONE IN FACTORY STOCK MK2

I repeated above steps twice and everytime - it works like charm...HE HE HE :) may be my luck :)

Sincerely,
[AT&T Samsung Galaxy S 4 General] muniz_ri:
Well that is interesting to say the least...in your previous post you mentioned that you flashed a file called "bl_nb1_test" .tar file. I checked the aboot in that file and confirmed that it is the NB1 aboot. Flashing that should prevent downgrading to factory MK2. The MK2 All in One file should fail in Odin after flashing NB1 aboot so I am at a loss. Thanks for posting this.

EDIT: I just re-read your reply. You said you flashed "PRE-ROOTED STOCK MK2 - ALL IN ONE TAR" is that a Custom ROM that you flashed in SS or did you flash that in Odin?
