[Galaxy Note 3 Android Development] Wrathlon:
I've seen quite a few posts of people with freezing after installing 4.4.2 no matter what they do and both myself and a friend have been at the mercy of this - myself with a custom rom and my friend with the Samsung OTA update.

From what I remember from back in the HD2 days with similar symptoms it's related to the baseband/modem - a check of both her phone and mine showed the baseband was incorrect for the ROM and updating it resolved the issue.

The following guide will flash the latest stock, unrooted, NB4 ROM with a matching modem/baseband.

Whilst it shouldn't affect Knox as everything is official signed files (and Knox is fine on my friends phone after I did this procedure), I take no responsibility for your own Knox status.

***THIS *SHOULDN'T* AFFECT KNOX IN ANY WAY AS YOU ARE ONLY FLASHING SIGNED STOCK SAMSUNG STUFF***

First off, backup anything on the phone you want to keep and download the following then extract them all to the same folder:

Samsung USB Drivers - http://developer.samsung.com/android...er-for-Windows

Odin - http://uploaded.net/file/hwtdrpll

Latest 4.4.2 Firmware - https://mega.co.nz/#!QVwlVDgJ!QyAxmD...TVvdM07LOs0V10

PIT File for 4.4.2 Firmware - http://xdaforums.com/show...9&postcount=77

NB1 Modem Firmware - https://mega.co.nz/#!JJBglRDY!ZT5SkT...4obRSKpB4B8NB1

1) Install Samsung Drivers

2) On your phone go Settings --> General --> About and keep tapping "Build Number" until it says developer mode enabled.

3) Go back to Settings --> General and tap Developer Options.

4) Tick enable "USB Debugging" then plug the phone into your computer.

5) Push and hold Volume Down + Home Button + Power Button all at the same time - hold until it goes black and vibrates indicating it

rebooted. Once it vibrates, release the power button but keep the other two held down - when you get the prompt on the screen press Volume Up - this will put the phone into Odin mode.

6) On the computer, right click Odin and click "Run as Administrator"

7) Click the button labelled PIT and select the file "My_N9005.pit"

8) Click the button labelled AP and select the file labelled "N9005XXUENB4_N9005DBTENB1_N9005XXUENB1_HOME.tar.m d5"

9) Make sure Re-Partition is ticked and click start.

10) When it finishes your phone will reboot - once you see the Samsung Logo, put the phone back into Odin Mode by pushing and holding Volume Down + Home Button + Power Button again, same as last time. Don't close Odin just yet.

12) In Odin, click Reset and then click the button labelled AP and select the file called "N9005XXUENB3_Modem-XXUENB1-LTE.tar.md5"

13) Click Start

14) When it finishes it should reboot. Dont panic about your phone appearing german, you can change the language right at the start on the first screen

***Optional Steps***

If your phone doesn't boot still, do the following:

1) Hold down Volume Up + Home Button + Power until it reboots, then release the power button keeping the other two held down (Basically the same as Odin mode except Volume Up instead of Volume Down).

2) You should now be in recovery - ignore any errors. Select Wipe Data/Factory Reset then Wipe Cache Partition - you don't need to reboot in between.

3) Once that's done, reboot and you should be up and running fine. If it still hasn't booted after 10 mins at this point, it's the phone itself most likely.
