[Verizon Galaxy Note 3 Q&A, Help & Troubleshooting] mikevipe:
I am posting this here because I saw others asking and with my experience last night these are the links and software guides and downloads I used to piece together the process of going to HD KK RLS8 from MJE.

Thanks and credit go to the people in the links who originally created these methods and small guides. I just brought them together in one easy to find resource based on my experience of performing this process.

You do this at your own risk.

I decided to take this plunge last night after my phone was damaged and my new replacement arrived in the mail. Here are my steps on how I went from Stock MJE (no root) to Hyperdrive Kitkat 4.4.2 rom with root and Safestrap 3.72

This guide assumes you already have your Samsung USB drivers installed as well as Odin downloaded. (As well as a basic knowledge on how to use it).

Step one: I was having problems with Kingo saying failing to root so I downloaded vroot from http://www.mgyun.com/en/getvroot

Parts of this are in Chinese, but you can use the common guess that OK is on the Right side of the popup, Cancel on the left. ETC. At some point it will ask to install the mlkcamera and root security app, you need to accept the install of these to obtain root. After doing so, vroot rooted my phone in under 2 minutes. It leaves behind two apps. You can follow http://www.w0lfdroid.com/2013/11/How-to-Remove-Replace-VRoot-Chinese-superuser-with-SuperSU.html for how to replace these two Chinese apps with the normal popular SuperSU.

Step two: Once rooted and with the new SuperSU installed, I then proceeded to install Safestrap 3.65. Found at http://xdaforums.com/showthread.php?t=2517610 (Both 3.65 and 3.72 download links are here, download both as you will need both).

Step three: Download and place the rom you wish to use onto your external SD CARD in your phone, for this example we will use the Stock 4.4.2 Kitkat with root available in Odex or Deodex. http://xdaforums.com/showthread.php?t=2726558

Step four: Next make sure to download the FIRMWARE link from the same link above, it is directly below the Odex or Deodex links. Make sure to extract this from its zip as it is currently in .md5.zip format which once extracted will be n900v_kk_firmware.tar.md5

Step five: Boot into safestrap recovery. Perform a default wipe of the system. Next make sure you are on the STOCK slot (should be by default). Now select Install and select the new hltevzw_root_odex_nc2.zip file. This will flash to your stock slot. DO NOT REBOOT HERE ONCE DONE, hit the back button in the bottom right corner to get back to the main page, then choose to reboot to DOWNLOAD mode.

Step six: Now your in download mode (and have already hit UP to start download mode). Open ODIN on your PC, plug in your phone and wait for it to identify its COM port. Now select the FIRMWARE file you previously downloaded and extracted: n900v_kk_firmware.tar.md5 in AP and click on Start. This now flashes the new firmware needed for Kitkat.

Step seven: Boot back into recovery and do one more wipe (I originally skipped this step but had a TON of FC app errors which I fixed by wiping again, hence adding this step) Then reboot into the stock Kit Kat 4.4.2 with root.

Step eight: Download safestrap 3.72, Run the new Safestrap and click the Uninstall recovery button, then click Install, next reboot to recovery!

At this point I booted into recovery and installed the ROM Hyperdrive, which is a 4.4.2 rooted highly tweaked rom which I have to say is ABSOLUTELY awesome. http://xdaforums.com/showthread.php?t=2520550 I flashed this to the STOCK spot and then wiped the data on the phone once more and rebooted! DO NOT FLASH THE FIRMWARE AGAIN from the NC2 rom.

Now I again reinstalled Safestrap 3.72 and am currently running Hyperdrive KK RLS8 w/ Safestrap 3.72 successfully!
