I'm currently on a Galaxy S3, but I have an S4 coming in on Friday.
I saw a thread for rooting the S4, but do I need to unlock the bootloader like I did in the S3 to install a rom?
Basically, where is the thread that has all the info I need to root, unlock, and install a custom recovery for the S4?
I have one for the S3, but can't find it for the S4.

you cant find thread? How hard did you look? There is a stickie can't be missed in the general section.
BTW, the bootloader is locked for all versions of firmware since mdk.
only option is safetrap.

Okay maybe my understanding on the purpose of unlocking the bootloader is incorrect.
I thought the bootloader has to be unlocked in order to install a custom rom?
On my S3 if the bootloader wasn't unlocked the phone would brick.
Safestrap is a custom recovery so how is that relevant to bootloader? I can't seem to draw the connection.
Thanks!

plenty of threads here to read to educate yourself.
S4 bootloader is locked since mdk firmware. MDK had an exploit that Loki process allowed custom recovery
safestrap uses an exploit to work around it so its the only custom recovery for the locked bootloader.
Each subsequent firmware release locks the bootloader and exploits down further. Anyone taking the next round of kit kat OTA's will likely loose root as well.

More then likely the device you get will come with the new baseband MJ7 or MK2. You need to check this before you start messing with anything. That said the bootloader is locked up tight and you will be very limited with what you can do with it. You can root, and install safestrap(a custom recovery by Hashcode that bypasses the bootloader). This will allow you to install certain touchwiz based roms but you have to be sure they are compatible with safestrap.
Root for 4.3 baseband:

Safestrap:

Both these links are in the android devlopment section. It is very difficult with this device because there are multiple root methods and recovery methods depending on baseband version. If by some chance you get the phone and the baseband is MDK, DO NOT UPDATE!!!! This will allow you to install loki'ed recovery and flash any rom you want. Chances are that won"t happen though. Good luck

I understand that I need to look into it, but the way things are organized is different. I've been on an S3 for almost two years now and the forums in the S4 are just overwhelming with information that is scattered. Here is an example of what I was hoping for when I came to the S4 section.

Thank you. This is the response I was looking for. As you said there are many stipulations with each baseband. This is something I am not used to coming for an S3, which is far simpler to deal with. Thanks again!

The difference isn't in the baseband, it's in the bootloader. You can run a newer baseband than your bootloader, for example, especially if you have the MDK bootloader.
Since you're starting from stock, the baseband and the bootloader revisions are the same and can be found from Settings/More/About phone.
Before you flash anything, please read the what you need to know thread in the General section. Also, there's my thread in this forum.
The S4 is more complicated than the S3 largely because Samsung has really locked it down much more effectively than the S3. Consequently, there's lots of ways to go wrong. Reading first can save you a lot of grief.

Is there a noticeable difference? If its the same, why upgrade?
I am coming from a similar situation as you. I cracked my screen on my S3 and Asurion replaced it with an S4, which I received on Monday. I thought that I was going to be able to load SlimKat and pick up where I left off, but no.
The posts that k1mu linked are a great starting point. A few of my thoughts that I came to realize this week. These are my ways of looking at it and may not be totally correct.
The bootloader is locked and there isn't a total unlock (yet). Safestrap allows you to crack the door open a little and reach your arm in to grab a few things.
You will need to stick with ROMs that work with the TouchWiz kernel. The post that k1mu referenced has a link to compatible ROMs. You will not be able to load SlimKat, CM, Carbon, etc. Basically any ROM you choose will have TW underneath. Some of the ROMs will try to look like an ASOP, but it is still a TW base.
Safestrap will allow you to create ROM slots where you can try out the ROM to see if you like it. I am still trying to decide what I want to use. Currently I have Hyperdrive as the leader. Everything that I do continues to work. The Eclipse ROM looks good but it is not quite there yet, but he is working on a build in the next couple days. Here is a link to their website with more up to date status. Eclipse . I also looked at the Foxhound ROM and it is good also. For me support and future upgrades are the most important. I am starting to think that i will embrace TW instead of trying to cover it up and will go with Hyperdrive.
If you use TiBu, read this post, especially with Hyperdrive http://forum.xda-developers.com/showthread.php?t=2653044.
The other realization that hit me was that while Safestrap can create partitions for loading different ROMs, each one is restricted to a maximum of a 3GB /data partition. When I tried to restore all of my apps this was quickly used up. It isn't supported by Safestrap to flash to the stock location, but it can and has been done. Since Safestrap isn't doing a flash there are more risks and I think that this should probably be kept to a minimum. This is where you want to test all the candidate ROMs first and then decide which one to use and then flash to the stock location. Obviously this could cause problems with the phone and would use ODIN as a fallback. Unless something get totally hosed and then you are out of a phone.
One thing that I realized a long time ago is that when you change devices you may want to do everything exactly the way it was before. On the phone or even when looking for information. But in most cases it is better to change your processes or work flow to work with the new device than it is to change the device to work in your previous work flow.

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".

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.

As the title states, I'm new to the S4, but not to flashing. I had the Fascinate (S1) for the past 3 years and did EVERYTHING with it! I picked up the S4 yesterday and have some questions.
I saw Shane's (DroidModderX) video on how to Root the S4 (ME7) and also his video on how to LOKI bootloader hack, but this all warns against not working after the l latest OTA. When I got the phone, the VZW tech made sure my phone was totally updated and so I'm sure I'm in that stuck area.
I'm working on backing up my SD card before I try formatting to extFAT, so I haven't done anything yet. But do I have any options available to me in terms of rooting/custom ROMs?
Not sure what the relevant information is for the S4, but I've attached my phone info.
You can root only currently. Hopefully SafeStrap wil be available soon to give you other options.

Safestrap is a very similar way to flash roms as phones that have UNLOCKED bootloaders. The main difference is that the bootloader is locked currently on S4. safestrap doesnt go around bootloader but it does give people the option to flash so custom roms, but you dont get the wide variety as you would on a unlocked bootloader phone.
Also I don't mean to ruin the fun, but the bootloader each year becomes tougher. The developer that did the LOKI mentioned once on a post that this would probably one of the last option he will be able to find a way to unlock bootloaders.
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 just need to know which version of Odin, how to root it, and which kernel and Custom recovery to use.
I do not want to use goomanager if can help it. I'd rather use my laptop.
Unfortunately since your phone has been updated you cannot completely unlock the bootloader. You will need to use Safestrap to load a recovery/ROM. More info can be found here:
http://forum.xda-developers.com/showthread.php?t=2441441
I would suggest rooting your phone using Towelroot:
https://towelroot.com/
Install SuperSU from the Play Store afterwards to complete the root access.
I can't give you much info about SafeStrap as I have never used it (I am on an unlocked bootloader).
To fully unlock the bootloader, you're going to need an S4 on the MDK firmware. I'd suggest heading over to Swappa, selling yours and picking up an unlocked S4. This is something I've done with every replacement Verizon has sent me...
So it's safe to assume that you can't just flash back to the mdk version via Odin or something then huh?

If you pick up one with an unlocked bootloader your opinion may change. I have had quite a few phone that I have unlocked and the S4 is by far my favorite.
This is a great tread but it should be moved in the Help section.
Agreed, this isn't a development thread.
But I can vouch for the S4 mdk bootloader being great. You can use a lot of stuff from I9505 and JFLTE unified threads on this phone. I have MDK and currently running unofficial CM 12 (android 5.0) with Alucard kernel. All this is from i9505 threads.
However, life is much more simple and stable with a Nexus device, I have Nexus 7 and much less bugs and rooting is so easy.

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.)

Oh, okay. Really unfortunate that this isn't possible now. So he's just stuck with TouchWiz and can't do anything about it?

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?

haha yeah, that could maybe potentially probably be the issue. Just maybe.
Couldn't you ODIN back to an older baseband version and then try to flash CM12?

Nope, in order to get CM, you'll need to be on MDK. Samsung prevents downgrading.
btw. the baseband version doesn't matter much. Its the bootloader version that is the toughie.
Boo! I just picked up my S4 yesterday after a 5 month run of using Windows Phone so I'm trying to figure this phone out. I'm on NK1 and trying to figure out how to root now.
vaindil where did you find a VRUFNK1 compatible version of Safestrip?
