While I install, rip apart, and get this ready for mass consumption, let us discuss!
A generous XDA member has hooked us up with a leak. They can be referred to as the Anti-Plumber, with more leaks than the Super Mario bros!
Keep in mind that in flashing this, you:
-Cannot go back to 4.3. Even if you restore a backup, the system will not boot.
-Cannot update via OTA since it will be for those on MJ4.
-You really cannot go back after flashing NAB. This is official software without an engineering bootloader (for now).
Going from MJ4 to NAB with the updater zip, this means that it is no longer possible to go back to prior bootloaders and Android versions, such as Android 4.3. Once the software is finalized and official, I will attempt to preserve the engineering bootloader with a flashable file i will make myself. So if you want to wait on that, I would suggest not flashing this, as I cannot verify the ability to downgrade after you've got an official 4.4.2 bootloader. Any attempts to downgrade is at your own risk, and cannot be officially supported in this thread.
NABD you ask? Yeah, there's an update from NAB to NABD. I have no idea what this means for us but I can only assume it's something...cool.....maybe. Below steps apply. You need to be on official NAB of course.
Make sure to be on official MJ4 (by flashing the MJ4 tar from Odin so that your binary and system are both official.)
After you're on MJ4, copy SM-N900P_MJ4_to_NAB.zip to your EXTERNAL SD. When done, power off your phone, and boot into STOCK recovery. From there, use the down arrows to select install from external then press the power button to confirm. Scroll down and select the copied zip, and press power to confirm.
If you have signature verification errors, you may need to reflash MJ4. It could be one of the following:
-Either your binary, system, or both are still "custom" in Odin/Android
-Incomplete zip download
Once done, power off and boot into download mode and from here, you will need to decide if you want to auto-reboot, if so leave the box check and prepare to hold down the volume+up and home keys immediately after your phone reboots from flashing the TWRP recovery to boot into recovery. If not, uncheck the auto-reboot box and flash the TWRP recovery from the PDA slot. If you've opted to not auto-reboot, once the flash is done, you will need to hold down the power key to power off your phone and boot into recovery.
Once you've successfully flashed and have booted into TWRP recovery, go ahead and flash the SuperSU zip that you downloaded from your phone. It should be in the Download folder.
Congratulations. You now have root! Enjoy!
