You can't downgrade to MDK. You can only reinstall the same version that you currently have, or update to a newer version.
There are no versions of the Verizon GS4 that have an unlocked bootloader. There's a method for MDK phones to bypass the bootloader lock (loki), but that's it.
At the moment, all you can do with MI1 is use safestrap and ROMs compatible with the stock MI1 kernel.
I have read that people have downgraded back to MDK with JTAG but I have also heard it is very risky and I would not know which direction to point you in.

I rooted my Verison Galaxy S4 before they updated the bootloader to ME7. If I wanted to unroot my phone can I follow the ME7 unroot instructions to update to Android 4.3 bypassing the update, or do I have to go back to what my phone was originally prior to updating?

Just. Don't. Do. It.
You have MDK Lokied bootloader apparently. If you take Verizon update they will ruin that! Wait for developers to incorporate the best 4.3 features in custom roms.

What is the best recovery to use for the Verizon S4 i545? I'm currently on MK2 and it appears the only recovery available is safestrap.
Is there anything better? If so, what makes it better? Thanks.
Is it possible to unlock the bootloader for MK2 yet?

Safestrap is it as of right now, and no.
So if I downgraded my NC5 i545 to MK2 could I then install CyanogenMod?
Thanks!

In a word - NO. Even going back to the MDK bootloader is not possible once you have taken the OTAs. And even then, MDK is still locked. The likelihood of the bootloader getting unlocked is slim and none. Kexec is the next choice and even its development has slowed as it is very hard to crack the bootloader issue.
As is often repeated, read the FAQs and search topics before posting.
To install anything other than a TW based rom, you need to be on the MDK bootloader. Once you have a newer bootloader than MDK, you are stuck with TW based roms and Safe Strap.
I have a Verizon Samsung Galaxy S4 on build lrx22c.i545vrugoc1 and would like to flash a Play Edition ROM.
Everything I have read so far suggests that it can not be done because Verizon locked the bootloader somehow with the latest update.
Can anyone point me in the right direction?
Thanks
You're correct, though the BL has always been locked. I don't believe there is any way to root the LL build as of now.

Actually, if you go into the different sections, root has been gained for updates after the initial MDK bootloader. MDK is still the only version of the bootloader that is capable of running custom roms without having to use safestrap.
Having root and the capability or ability of running custom roms are two horses of a different color.
I didn't say you couldn't root different builds, i said the bootloader has never been unlocked.
If you are on oc1 boot loader there is no way to root and you can't downgrade from oc1 so you can't gain root

I have OC1 update and a rooted i545
OC1 CAN be rooted with KingRoot. Many people reported that the chinese app works.
As far as ROMs for OC1, there is nothing like AOSP. Only Touchwiz ones. Only Play edition SIMILAR ROMs are eclipse and Kitpop, which you cannot do because you are on OC1. You can Root, and get a stockdeodex ROM, that is about it.
The bootloader has been locked for ages. Only unlocked bootloader is for MDK, which was about 2-3 years back. No hack for the bootloader has been found as of yet.
Hi , I recently bought a Verizon S4 that came with a Baseband Version of I545VRUFNG6. Although I know that only Baseband Version VRUAMDK has an exploit which allows for unocking the system and placing a custom bootloader on it, I must ask: are there any options for this phone on this specific baseband? Are there any ROMS or a way to use FlashFire to get an Android version higher than 4.4.2? Or is there any way of downgrading the bootloader to VRUAMDK. I've read that downgrading to 4.3 is not possible. Just curious. Thanks!

Downgrading to MDK is not possible. You can root the system easily, there are multiple guides for doing so. You'll have to use safe strap to flash anything, or you can upgrade to lollipop and root and flash with v0.53 Flashfire.
Thank you.

I appreciate you confirming any previous thoughts I had. Thank you very much.
A very common mistake is that people think Loki unlocks the bootloader. It does not. Loki doki was a bypass exploit, meaning the bootloader is still locked, just you're by passing the lock with it. Think of it as using a credit card to open a locked door. The lock is still locked yet the door is opened.
