Is this downgrading from ME7 to MDK possible? If so please guide me in the right direction.
Its not possible... Once you take the update theres no going back...

So I am new to the s4 and rooting. I really want to install the Hyperdrive ROM. I have been researching and researching what to do and I think i have found my answer for now and im not happy about it.
From what i gathered, since i installed the update and I am now on ME7, there is no root method bc they locked the phone down. Is this correct?

Thanks for being kind and thanks for the info. I did state that I was new and have been looking. I could have started a whole new thread but instead asked the question in here. I do want to install the Hyperdrive rom but since with ME7 you cant install roms...looks like i wont be rooting until somebody gets this figured out. Again, thanks for being cool and answering my question.
y can't we just odin back to mdk?

because of the bootloader will only allow signed packages to be installed on the phone and checks against older firmware and will not allow it. Unless you have the signed key you ain't flashing anything unless we find a workaround.

So why is there ROMs for the ME7 build if they can't be flashed?
This [email protected] sucks!
So, I'm stuck on ME7 as well (32GB S4, otherwise I'd just go down to the store and swap it, complaining about something -- seems they don't stock them at any local corporate stores).
I'm coming from a Samsung Galaxy Nexus, and we have OMAP-Flash, which is like a low-level PROM flashing tool from the Samsung R&D team, and I could fix even a DEAD, or bricked phone with that. Is there something like that here to get back the original bootloader? I cant believe we're stuck on this crap... How 'bout a 2nd-init like my Droid-x days, or something slick like SafeStrap on the RAZR family?
...Just thinkin' "out loud".

Short answer is 'no' - you're currently stuck with root as your best option. Hopefully this will change in the not-too-distant future.

Seems like we need someone to pick up the Dragonboard 8074 development kit to help us figure this out...even then, I'm sure Samsung has so many mods in there it'd be nuts to reverse engineer... Ugh, I'm so impatient! :silly:

You're not quite understanding what a rom is and is not. There is no such thing as a rom for ME7. There are roms that use the ME7 base. They are flashable only by those who have the MDK bootloader. When a build number is listed for a rom, it is the build that the rom is based from.

The ROM's that the devs based on MDK have been updated with the ME7 code just like any good developer does. But the bootloader those users have is still from their MDK (original) install. Once you go ME7 you can never go back, downgrade, crossgrade or get beyond the bootloader, for now anyways. Someone will find a way.

I'm pretty familiar with flashing with odin, using cwm recovery on the droid charge.
I'm a total noob for the s4 though.
i'm looking at http://forum.xda-developers.com/showthread.php?t=2301724&highlight=+odin+
I'm concerned with the line:
This Rom will run on any Verizon Galaxy S4 on the MDK Base with Root and loki Recovery or Galaxy S4 on the ME7 Base with Safestrap installed.
How can I determine what base i have and which parts of said sentence are referring to modded parts and stock parts?
Are "Base" and "Baseband version" the same thing?
Your device is on me7 base. That means you will have to root and use safestrap to use custom roms. There is a thread i development forum about rooting me7 and loading safestrap. Good luck and read lots before flashing anything and follow directions exactly.

The "Build Number" is what you're concerned about. For your phone, the build number is VRUEMJ7, which means that there's no (trustworthy) program that'll root that. You're stuck with stock for now.

Thanks again.
My galaxy s4 was stuck in factory mode and it seemed like there was nothing i could do. I though i had nothing to lose so i decided to update from MDK to ME7 threw odin and it fixed the problem so if your like me and have nothing to lose try updating .
Sorry but that is BAD advice. It's never good to update from MDK to anything else. You should have just Odin back to stock MDK firmware and reroot and flashed recovery. Bad/dumb move imo.

Updating may soon not be such a big deal...got a group of great devs who may have had a huge breakthrough in the form of kexec kernel modules that may soon allow newer bootloaders to run custom ROMs based on aosp and not be limited to touchwiz...kexec lead to a fully unlocked boot loader on vzw gs3 and could bring this"for the love of god don't update" crap to an end!

Well lets just say i tried that... and i did not work.
Maybe but you're still using safestrap to hijack the boot sequence so your adding a rom on top of your stock rom giving you less room on your s4. I understand safestrap very well as I came from a DROID Bionic using SS then SS with kexec. I would still never give up MDK. If I had to ever replace my s4 with another s4 i'd be thankful for SS emencely but I'd never willingly give up MDK. And that's all I'm saying, I would never recommend giving MDK.

Ok, a little info on me. I have had an iPhone since 2007. I decided to buy a used G S4 to see if I would like it. So far I like it a lot but need help getting it just right.
I am trying to install custom roms on my device. I want to try CM.10 first. So far I have achieved root aaccess, and installed gooManager.
The problem is that when I install a custom recovery script so I can have a custom recovery the phone locks up. What could I be doing wrong? I am sure this has been covered a hundred times but there is so much info on here its overwhelming to someone new to android. Thanks to everyone for the great work and contributions s already made.
Try odin to flash!

I watched all of the videos. Do I have a locked boot loader? Does that keep me from installing open recovery script? If so do I need a device with an older baseband in order to root, install custom recovery, and run custom roms?
I have a SCH-I545 running 4.3 with an mk2 baseband.
Yes, your bootloader is locked and currently there is no way to unlock it. Safestrap is your only option for ROMs now. Start with reading the OP.

People have em up for sale, just look for the last three letters of the build (or baseband I suppose) to be MDK. Anything newer than that is locked down.

Information is easily available in these forums concerning bootloaders and rooting and recoveries....with you phone your only option is safestrap and just one or 2 roms are available..

I will be honest this is the first phone that i have ever been satisfied with rooted debloated stock but I am very greatful my flashing itch is able to be somewhat scratched with safestrap.

the stock roms run extremely well and with root you can debloat pretty easily. S4 phone is a superior device to most anything else out there at this moment whether you mod it or not
Hey your in luck there is a guy selling his mdk s4 for 330 on the general thread.
I asked a similar question back in October, but fell out of the loop again and didn't want to necro an old post. I just want to verify that the information I got back then is still relavent.
Is installing custom ROMs still the best way to bring my MDK S4 up to the current version? If so, what should I be looking for in a ROM title to tell me that it's just a stock ROM that gives the same experience as the OTA? Someone mentioned Deodex'd in my last post, but I have no idea what that means or if it's what I should be looking for.
And for an S4 that came stock with ME7? Should my girlfriend (with an ME7 update) just take the newest OTA and root that, or is there a benefit to sticking with ME7 and installing a ROM? If the answer is to go with a ROM then she'll want the stock new OTA experience as well for now, are there any ME7 ROMs available that can do that?
Thanks again guys!
Don't touch your MDK S4. Leave it on MDK with Loki. It's practically an unlocked bootloader with actual TWRP and CWM. You can still install 4.3 TouchWiz stock ROMs on it because you can change the kernel. Plus you can run AOSP ROMs, which is awesome.

You're girls me7 s4 might as well update to mj7 or mk2 (4.3) as then she'll still be using Safestrap. Mostly everyone is running Hyperdrive anyways. Great performance and battery life with that. Update it, throw Safestrap 3.71 on there then Hyperdrive 12....pretty much bug free.
As far as you're MDK phone just grab whatever AOSP 4.3 or 4.4 ROM you like. You're lucky to have that phone!!

I had it rooted and got rid of all the bloatware from Verizon using titanium. Would that have something to do with it? Otherwise, I don't know what's going on. Thank you, and I apologize if this was addressed in any other thread.

No its not supposed to take that long. So you're trying to take the ota from me7 you're saying right? You may have to Odin if that doesn't work for you. Sometimes unfreezing and removing mods just doesn't do it

I have the same exact phone and with Safestrap 3.71 installed I have some great roms (Foxhound, Echoe, Nemesis 1.5). While you cannot install a different kernel you can still mod these a lot. One advantage to safestrap is you can go back and forth with roms easily. Put in at least a 32gb micro card (64 gb would be better since these roms files are quite large). You can still have a lot of fun.
Unless you want to specifically run ROMs. Xposed and Wanam offer quite a bit of control.
In the same boat as you. The most that you can do now is root and use Safestrap to install Hyperdrive or other supported roms. It doesn't seem like the bootloader for MJ7 will be unlocked anytime soon. It's a great shame that in the 4.3 update Verizon locked the bootloader.
