Is there anything I can do to roll back to MDK BASEBAND so I can actually unlock the bootloader? I am currently on MK2 stock ROM.
Is it even possible to unlock the bootloader on MDK? I have spend over 6 hours researching and trying to figure this thing out. I really want to stay away from safestrap...
Can someone point me to a thread or explain this to me? I can't seem to find anything relevant to this question.

No way to rollback to MDK my friend - the only ones on MDK are us lucky sods that got it that way and kept it. The bootloader is not unlocked on MDK - workaround is available using Loki exploit. Verizon quickly closed that hole with subsequent "upgrades". At this point safestrap is your only option.

So there is no way to NUKE the phone and push the original MDK Baseband to the phone like it was done at the factory? : (

I have an HTC One that I converted to a GPE. My fiance has a VZW Galaxy S4 and is jealous. I found a Google Play ROM on here that I'd like to flash (http://forum.xda-developers.com/showthread.php?t=2643031), but I am not sure it will work with her phone. She has a SCH-I545 running the latest 4.3 release from VZW. I rooted the device last week and besides that haven't done anything to the phone ever.
There was a post in that thread that seemed to indicate that I would not be able to load the ROM I'd like due to it requiring Loki and something about the bootloader being locked on her version. This is where I kind of lose it. I am not familiar with Loki, but TWRP for the VZW Galaxy S4 states that it has been modified with Loki (http://teamw.in/project/twrp2/181). In my head it makes sense that since I have root, I can load TWRP recovery and use that to flash the ROM to the device, and that it would work because TWRP has been modified with Loki.
Can someone advise me on this? I have held off on anything beyond root since I haven't been able to find a definite answer.

I suspect you have the MK2 build and bootloader if you're on 4.3. I recommend you read this thread, it will answer your questions: http://forum.xda-developers.com/showthread.php?t=2578569

Yes, sorry I left that detail out. Definitely on MK2.
Thanks for the resource, I will read that.
I have a gs4 with an unlocked bootloader (MDK baseband). The data port on mine went south, so I'm looking for another one on swappa. I found one but the baseband does not have mdk in it. It's rooted with 4.4.4, so I know it has an unlocked bootloader. The phone I have now has the mdk in the baseband. My question is how can this be? I know it's been updated, but I didn't think you could update it without loosing the unlocked bootloader. Thanks

You could try to fix it yourself, or buy a replacement port and find a small electronics repair shop to do it for you...

Being rooted doesn't mean you have an unlocked bootloader. They are two completely different things. That being said, you should try everything you can to hold on to your MDK phone. They are like gold around here now.

I've rooted a mek device using towelroot. and it didnt have a unlocked bootloader.So like the above poster said, just cause its rooted doesn't mean its MDK
Also, keep in mind that you can't always go by what the build number in About Phone says...cuz even though I have MDK firmware, my build number in the ROM I'm running says that my build number is NE5.
A great tool for determining the ACTUAL firmware/build number is Samsung Phone Info from the Play Store
Keep it kid!
Thanks for your input. I will buy the charge port from the link you provided. I never even thought about fixing it myself. Good job. Thanks again
I am currently running a Verizon Samsung Galaxy S4 SCH-i545 NC5. I've been wanting CyanogenMod for a while now, but from what it seems the bootloader is completely locked for the S4. I have read that it is possible to downgrade to an older version to get the unlocked bootloader, is this possible? If it is possible I don't know which version to downgrade to... ME7, MDK, MJ7?
Thanks
not possible. if you're running MDK you can do the loki exploit but anything other than MDK is not able to be patched, worked around, etc.

Ok thanks, but I have seen downgrade videos on YouTube, I haven't tried it but I'm guessing that if you do this you keep your baseband version?

Follow the video if you want. If you manager to downgrade to MDK you can TOTALLY use the loki exploit to work around the locked bootloader and use a custom recover.
However, you can't downgrade a Verizon S4 to MDK. If you manage to get the software on your phone, it wont boot (or your really smart). There is a 148 page thread at the very top of this forum called "If we are serious about unlocking the bootloader". You think that would still be going if you could just downgrade?

Haha Ok thanks for the help, I'll probably just wait until I get the Nexus 5 and stick with the Eclipse ROM

Dont think it would even work. It verifies something (Think it was the MD5 or something?) in the file and if its a lower version it will just block you from proceeding.

There's a bootloader value number and firmware won't flash if it has a lower number. Firmwares such as nc5 and nc2, as well as mk2 and mj7, can be downgraded because they have the same bootloader value.
I want to upgrade from NG6 to NK1 to hopefully get rid of thoes randome reboots but am wondering if by some chance the bootloader does some how get unlocked if I am runing my chance by updating? Thanks

No they r no chances it will get unlock. So upgrade to NK1 to stop the reboots
I think I read that you can still Odin back to NG6 or maybe even NC5... I don't think have incremented what ever flag it is that prevents you from downgrading on the last few updates... Can anyone confirm?
I know we def csn go from nk1 to nc5 and then root but i didnt know if it would brand your phone a whole update more bc say a person has a firmware update that can have an unlicked boot loader if they update they are forever locked in the higher firmware.

From what I've read you can fully downgrade from nk1 to nc5
I gave up caring about bootloader it just isn't going to happen unless something gets leaked. If I have root in happy. I just hope lollipop can be rooted when it drops or I'll be stuck on KitKat

Nobody can honestly answer this. The odds are very, very, very slim that the BL will ever be unlocked, and it is not known what firmware you would need to be on for an unlock to work until by some miracle it happens.
So as long as you can get root...... update.
Bootloader will never get unlocked so it does not matter.
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.
