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.

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?

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.

This is for root. With ME7 you can not use a custom recovery just as a FYI. But safestrap recovery works with ME7. You can find that also in the android Dev section.

Each firmware version has its own method, and theres only 1 for each. Since your on me7 you have to use the .pwn method and once your rooted you can reformat your card/delete the files that were used.

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.

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.

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!!

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.

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:
http://forum.xda-developers.com/showthread.php?t=2565758
Safestrap:
http://forum.xda-developers.com/showthread.php?t=2441441
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

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.

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.

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.

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.

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.

One more question. Is there a way to flash the s4 back to stock? I'll find the info on how, but going into the whole rooting and coming phase it would be nice to know that I could flash back to stock with odin. As I have with my s3.

Yes. Read the second link in my reply above - it tells you how to identify what build you're on and has links to the downloadable Odin images for each build.

Thanks for your help. Turns out I'm on MJ7. I'm going to let this puppy charge while I hit the gym. I'll root it and see what rom I can install later tonight. Thanks again!! :victory:

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.
