Hello,
I have a Galaxy S4 Developers Edition (SCH-I545, running Android 4.2.2), Baseband version YUAMDK. I would like to install Kitkat on it. The problem is that I cant seem to find clear instrcutions on what I need to do to install a different ROM on it. Can some one please help. Also as a side question, where can I find the stock samsung kitkat ROM for our phone.
Thank you

Thank you, is the process for being able to to load another ROM... all the ones I have seen are not for the Developers edition.
Thanks again.

You have a Developer Edition S4, you can flash just about any ROM you want on it...it has an unlocked bootloader. Not sure what recovery you have, but you'll need a custom recovery like TWRP (I recommend 2.5.0.2) or PhilZ. Either one of those can be found in this forum. The one thing you don't want to do is take an Over The Air Update from Verizon...or anywhere else for that matter. Your in good shape for flashing just about anything as long as you don't change/replace your bootloader. I haven't seen any ROMs on this forum that touches the bootloader. There are a number of good ROMs available. Just follow the Developer's installation instructions. If you're looking for a really good TW ROM I recommend trying Eclipse 3.0.

Here is a good thread for you to read. It probably answers a lot of your questions: http://forum.xda-developers.com/showthread.php?t=2578569
Just keep in mind there is no factory image for the dev edition Gs4, (each developer edition device supposedly has a slightly different aboot) this is why no ota updates from big red.
I dont know how to do it but get some advice on how to back up your factory firmware before going to far. If this is even possible without a custom recovery????
Don't make the mistake I made and get a soft brick and have to flash a consumer version of mdk. My bootloader is now locked but at least I am still mdk with custom recovery and flashing capability.

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.

Check out www.swappa.com
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..
look before you jump
Nobody posts the build number in their adds on ebay or that swappers site. I'm messaging them all individually haha. Lmfao why didn't I read about this more before buying this boot locked pos lol.

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 above builds aren't worthless but I guess that all depends on your point of view and what your wanting to do with your device.

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.
Hi everyone! I need some help updating my S4. I rooted it awhile back and I'm very much of the mindset of "if it ain't broke, don't fix it," so since it was doing everything I wanted, I've just left it alone and kept dismissing the prompt to install the OTA update. Now I'm having some issues and want some features of the newer versions of Android, so I was looking around for the best way to update it while keeping my root access. All the guides I can find, however, talk about upgrading from 4.3 to 4.4 or 4.2 to 4.3. So I was wondering...
1. What version should I update to? On my last phone, a Droid Bionic, one of the big Android version updates ran so horribly on it that I ended up getting a new phone. Because of that, I'm very nervous about updating my phone and having the performance suffer.
2. There must be a way to go straight from 4.2.2 to whatever version I choose, right? Do I need to go dig up some old guides on how to update my phone so that the most recent guides are relevant?
I hope I'm not being a super noob about this. I tried Googling around, and I'm pretty tech savvy but just haven't had the time to keep up with recent developments, so some guidance would be very helpful!
About my phone:
Verizon Galaxy S4
Model #: SCH-I545
Android version: 4.2.2
Baseband version: I545VRUDMI1
Thanks so much!
Find out what base band you have, MDK, ME7?
If MDK, install recovery download rom.
Anything other check this thread out:

I put the baseband version of my phone in my original post. It's I545VRUDMI1. Or am I missing something? So that means I should use Odin to flash whatever rom I decide to go with, right? So if I went with something like this 4.4.4 Google Play Edition I can use Odin to put it on my device? But then if I decide I don't like that rom for whatever reason, I can't redo it with any roms based on an earlier version (4.4.2, 4.3, etc), but other 4.4.4 roms would work?
Thanks so much for the help!

You need a custom recovery to flash that Play Edition ROM which is not possible with your MI1 baseband.

Sorry, the Verizon, and AT&T variants of the Galaxy S4 bootloaders cannot be unlocked at the moment. For the time being it will be impossible for us to install Lollipop until the official firmware release by Samsung. However, if you have a older S4 it *may* have the loki vulnerability which let's you bypass the locked bootloader. Check your About Phone and see if your running MDB or MDL.

No dice for running Lollipop ROM's yet, however you should able to install Safestrap 3.75 and use custom 4.4.2 (and a few 4.4.4) TouchWiz-based ROM's that are floating around the forum. Poke around the threads in both the AT&T and Verizon subforums to find more information.

Damn it, I wanted to ditch TouchWiz and try Lollipop. Been thinking of switching to iPhone and I wanted to see if Lollipop was worth sticking around for.
Hi,

I just haven't seen any recent threads........
Any help is appreciated.

Considering you're in the S4 forum, you're also unlikely to see any S3 threads in the future.
I'll bump this thread again since it applies. I'm on 4.4.2 NK1 can I unlock this bootloader? Should I just take the Lolipop update that keeps asking me to push through? What is my best step from here, I don't want to get stuck on something I hate.
Are there any better choices? I hate using ROM slots etc.
Thank you,
I'm helping my friend install CyanogenMod 12 on his S4 (jfltevzw). We've rooted it and we're currently doing a full backup through Safestrap in case anything happens. Once that's finished, I'm unsure as to what we should do. CyanogenMod's wiki has installation instructions for the Verizon S4, but it says in big bold letters to not attempt this if on a ROM newer than I545VRUAMDK. He's on the latest version that Samsung/Verizon have pushed out, which is I545VRUFNK1. Is there an alternate way to install CyanogenMod on top of the newer stock ROM, or is it not possible?

Dang, so there's absolutely nothing whatsoever that can be done? The page says you can't downgrade, but is anything at all possible now that he's beyond the MDK build? He really wants to make the switch and is fine with doing a complete wipe or whatever is necessary.
EDIT: I've been trying to read up on the VZW S4 and why this isn't possible, but I don't quite get it. Reading other threads it seems like the reason is because the bootloader is locked, but that can't be the case if he was able to install Safestrap. I'm coming from a Nexus 5 where everything is incredibly simple, so I apologize for my ignorance. (I don't mean to say you're wrong or anything as I have no idea myself, I just don't understand why it doesn't work on newer ROMs.)

you can install hyperdrive rom
its not lolipop but its worlds better then stock ...
also there is a chance of getting the 5.01 GPE edition rom running when Samsung releases the lolipop update for the vz s4
that would at least give us a working lolipop kernel to use with the gpe rombase
and hey you never know there could be a exploite in the lolipop rom/kernel that lets us get kexec working
Basically safestrap loads after the kernel but early enough to replace point to a different root for the system. So we can load what ever system we want... But are stuck with the kernel the phone booted. If the system is based on the stock kernel this is fine... But when it starts making calls to custom kernel stuff you will have trouble.
So Cyanogenmod only provides the GUI? I've installed CM on two B&N tablets and I've been asked to root a new Verizon Samsung Galaxy S4. I've assumed that, because it's new, it will have I545VRUFNK1 4.4.2. I rooted my VSG s3 years ago to 4.3 and there was no going back on that one. It looks like it's the same with VSG s4. So, if CM provides only the GUI, then a rooted VSG s4 can still access Google Apps? What is the concern with with TW based ROMs? Is it the recovery/backup feature or only being stuck with the VSG s4 GUI?

Nope, in order to get CM, you'll need to be on MDK. Samsung prevents downgrading.

Right now the bootloader is still locked down for the Verizon (unless your phone is on the MDK bootloader). So unfortunately you won't be able to do more than root the phone. You can use Safestrap to use some ROMs, but I don't think CM exists for the Verizon S4.

There is a Cyanogen build for the Verizon GS4 but as mentioned, only for folks with the MDK bootloader. Only TouchWiz based roms can be used with SafeStrap - no AOSP based roms (yet).
To see what bootlader you are on, just go to ABOUT PHONE under settings.
