4.4.2 root nb1 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a question. If nb1 is unrootable now, how can a pre rooted nb1 rom exist? And also, if i use safestrap method, since safestrap installs the rom along the stock, wont the usable internal storage become smaller?

This thread has some info.
Also, you can replace stock rom itself through safestrap

See the above for how the stock rooted NB1 was made.

on top of stock rom, my stock rom was JeallyBean 4.2.2 i337 mf3 not mdl and i read there are no mf3 files for odin
So i managed to fix this problem just by downloading stock rom for my phone and flashing with safestrap: Galaxy S4 rooted Stock ROM AT&T SGH-i337 MF3 (i found that on google)
The rom i downloader is rooted. and it said to install Loki after finishing flashing rom but i managed not to.
after you finished flashing you need to install also: jflteatt-MF3-modules(attachment) : this will make your wifi to work.
Every thing i just said, worked for me! do this at your own risk! im not responsible for any damages!!!
Wait what if you flash MDL with safestrap, and use goo.im for TWRP? It could possibly brick but just an idea.

It wouldn't. The bootloader is still MF3 no matter what you do to the system, and so it will still be locked with no way to bypass it.

Stay on MF3 or update to MK2

Should i stay on MF3 or update to mk2? (I want to flash custom roms. I know that safestrap is available for mf3 but i don't plan on using it)
Stay

[Q] how to remove root files after nb1 update

I was rooted on 4.3 and then I unrooted abd did it a update to nb1. Now when I try to use ISIS it says phone has been rooted. I know there is a work around but you have to be rooted for it. Is there a way I can remove whatever file ISIS is seeing that is making it think three phone is rooted when it's not.
Are you sure you're on NB1?If you're not, you will have to get pure stock 4.3 and flash via Odin

Yea I am on NB1, I was thinking of going back to MK2 doing a full unroot with removal of the backed up superuser. Then upgrading back to NB1. I will try it tonight to see if that will work.
You won't be able to downgrade to MK2

4.4.2 downgrade

so i took the 4,4.2 ota but ive read that root is not out for it yet, but still only certain recoveries and roms will work.
is there a way i can downgrade then install a recovery to flash an aosp/google play edition 4.4.2 rom?

There are plenty of threads with information in the general section, including a thread convienently named All Things MK2 And NB1. Make sure to check that and read more before asking questions unless you're on an I337m, in which case you can disregard anything I've said ;P

Stuck in Odin

I am running stock AT&T 4.2.2 MF3 rooted with Motochopper, I believe.
An OTA downloaded on my device today, NC1 I guess? I knew I couldn't install it because either it would fail after detecting root, or I would potentially brick.
I wanted to update to stock NB1 or NC1 (maintaining or re-establishing root afterward).
The MF3 update threads I have found seem outdated.
Please let me know what the safest way to flash the latest stock that is rootable.
Thanks in advance.

Hello, Sixftsix, I am in the same boat as you. MF3 rooted wanting to upgrade to NC1. Did it successfully work for you? The files say NB1 to NC1 not MF3 to NC1 so I was just wondering if it worked. Also what version of Safestrap did you use?
Thank you very much!

I haven't upgraded yet, I'm still confused on what is the proper/safest method.
I am not sure if we have to go from MF3 > MK2 > NB1 > NC1... or if we can go directly to NB1 with this: "NB1 STOCK -- Get to NB1 Stock from NB1 or earlier... I337UCUFNB1 4.4 Stock Odin Tar & System Dump", then use the NB1 to NC1 method.
Let me know if you attempt anything and the results, I will do the same. I did lot of reading with no clear answers.
If anyone can confirm the best method, I would appreciate your help!

Apparently you need to upgrade to MK2, root, then do MK2 to NB1, and then NB1 to NC1. Its a process. I think I'll just stick with 4.2.2 until a root method is available for KitKat then I'll just upgrade to KitKat instead of flashing because I always have bad luck when it comes to soft modding...
Good luck.

If you want NB1, you can flash straight to it with the ODIN package. If you want root, you can flash to either MK2 or NB1 but going to NB1 adds in the downgrade steps.

Thank you! One question. I use Linux so I wouldn't be using ODIN I would be flashing with Heimdall. Same thing right?

Slightly different. You'll have to extract the partitions to flash from the ODIN file since it doesn't work with ODIN packages directly. Alternatively, you could try JODIN3.
