What's needed to work on the Bootloader

What are we needing in order to figure out how to unlock or bypass the AT&T Bootloader?
I downloaded the stock files and have the aboot.mbn and the sbl1/sdi.mdn files. I have never worked on bootloader files before, but have some experience modding kernel and ROM level code.
This may be ignorant on my part - but since we have the files, couldn't we open and manipulate the code that is currently restricting 3rd party recoveries, kernels and ROMS?
What is needed? And/or, could we not utilize the modified bootloaders from another device with similar architecture? Perhaps like the Note 3 or even the S4; not to mention the T-Mobile S5? Since the T-Mobile and AT&T versions of all Samsung phones are almost identical, I would assume that would be the easist route - at least to help determine the differences that are restricting our device.....
Let me know if anyone needs these files or has info on what to look for within them.... I'm happy to mod anything on my end.
Thanks !

Because it is locked we can't just flash over it with another one due to signatures and miss match.
Need to research into the os and associated code to find an exploit that can be used like safestrap.

Or if someone that works at AT&T or Samsung would be nice enough to leak a signing key or a signed unlocked bootloader.

Key from Tmobile S5
T-mobile S5 is rooted. Can we find the signing key used for Tmobile phones? Is there is a remote chance keys are same?
Will recoveries on Tmobile and ATT phone be same?

Thats a good question. I wonder if we know how many keys the S5 will accept for signed updates? I.e. Is there a Samsung and a AT&T key for all S5's or is it per model or is it derived somehow from the IEMI.

Why would the developers even waste their time on the AT&T S5? They know the story behind it. Same ol' thing. I would rather have them actually develop roms on the T-Mobile S5, which we all can use btw, instead of wasting time on trying to unlock the bootloader. If it could be hacked, it would have, LONG AGO!

Well to be fair, if you took the best developers and hardware/software hackers in the world and put them in a room with an amazing salary.. it would be hacked..
So lets not say that its impossible. It is just extremely difficult and beyond the scope of the few developers (if any) that are still around trying to crack into it. The problem is that there aren't that many people that just want to sit around trying to figure out a way to make it work, they would rather move to different phones and carriers instead, because its just overall easier.

Yep, hate to burst anyone's bubble who has a G900A, but it's not going to happen... EVER. Options are to hold out for a developer edition phone from Samsung or get a T-mobile version... which is exactly the same thing minus the restrictions. Or if you are pissed at AT&T, just find another carrier. Maybe if there was enough churn from this, they would stop doing it.

The s5 will get root same as the s4 did. People just need to be patient. There is definitely a dev that is working to unlock this thing. Everyone said the same thing about the s4 and now look

Exactly. It can be done and it will be done. Anyone thinking otherwise is pretty naive. But then again, it's expected from those who don't even have the AT&T model, but continue to post in the AT&T section.

No. Again, there is a difference from root and unlocking the bootloader. I was referring to the bootloader as that's what this thread is discussing. I never said it was impossible, it is quite possible just takes a lot of hard work. My prediction is that it will never be fully unlocked.

I don't want to even have to worry about if it will or not, because I don't know who or how many are working on an exploit..

I think the problem is SELinux is an extremely tough nut to crack(and I'm guessing you could easily get a six figure payday for an unknown SELinux/PaX kernel exploit in the black market at this point). Pretty much every linux kernel vulnerability exploit code I've seen fails on all of my boxes with SELinux, PAX and hardened GCC(one of these protection mechanisms always ends up killing the exploit before it can deliver its payload). Do we know exactly what SELinux and PAX(if any) features were enabled in the .config that Samsung used to compile the kernel (and if a hardened toolchain was used for the userland)? At least from what I've seen a properly configured SELinux box with Pax and hardened GCC is one of the toughest boxes to crack. I guess what we can hope for is that someone at Samsung did something stupid otherwise its quite possible we could be waiting for awhile(unless a key or signed unlocked bootloader leaks).
(edit: This applies to getting root through a kernel exploit.(Although with SELinux that isn't enough you need to not only be UID0 root but you also have to switch the role to sysadm_r. The bootloader I'm not 100 percent sure on the secure boot process but my understanding from reading other dev's threads is that this will be even harder than getting a root escalation in the SELinux kernel). Although if we could crack the bl we could just inject root easily.

AT&T Lollipop update releaed..

Lucky me, just got my Note 4 yesterday and checked for software updates just now and low and behold I'm receiving Lollipop, its a 1161.38mb download..

you sure it's lollipop? i know my note 4 received two updates in the past month.

Getting an update on SM-N10A(stock. not rooted) on ATT network. . Its a 1161.38 MB file. Will update on which version does it get updated to shortly.
Update 1: 2.20PM CT: LOL. Installation failed. Try again in 21 hours. Sigh!

And tell you it's TBD. My old co-worker who now works at Rogers looked into it and apparently Samsung isn't releasing that information. As he said it's policy it classify devices that don't get support as TBD as to not piss off customers. Aka it's a coin toss if they are going to release it.
AT&T isn't the same as our devices. The closest we can get is T-Mobile. If and when TMO gets the update we won't be far behind. At least we shouldn't.

Yeah, I know of that link and they have pointed me there before. I've had a dialog going with them actually. I would like to rattle their cages "in public" as much as possible and Twitter is a good way to do that. I really was surprised to just get the Note 4 about 2 weeks ago, thinking it was the current flagship phone and then find out they have no idea when they are going to release Lollipop on it. Just bizarre.
A coin toss? How can a phone that hasn't been out for even 5 months yet not get Lollipop?

I was referring to the 5.0.1 update. It's very possible they will just lazily skip it and go for 5.1
If thats the case we most likely won't see a LP update this year. Remember Samsung had the oportunity to start LP in June and it has taken them 9 months just to get to this point. Considering no Canadian Carriers have been informed of the update even arriving, meaning they have not tested them and that in turn could create another month or two of testing. It's also been disclosed that Samsung has no plans on working on 5.1 at the moment. Let's assume that they wait to give us 5.1 instead of pushing 5.0.1 out. Since they have not even started 5.1 we can assume they might start in two months (Highly doubt it would be that quick). Then if we take the first time frame we add another 9 months plus the fact they wait a month after they build (check the build logs) we are at a total time frame of 12 months out for a single update. Skipping 5.0.1 would mean a total of 21 months of development time before the first actual LP update.
Of course remember this is all assumptions and theory based on what we have seen so far and I could be totally off. At least I hope I am.

Just the usual AT&T crap... Google Service needs to be updated after Lollipop installs, GS took multiple attempts to finally install, otherwise you keep getting a notice that the update is required.. Not sure if was just me but I had to reboot a few times to finally get the Install option to pop up..
So far I'm liking Lollipop, Visually much more appealing..

Couldn't agree with you more. I mean their service is excellent but all these limitations are not appreciated. But I guess that's what bands us together to keep on searching for ways to seek freedom between the cracks.

Will anything past OE2 ever get Root? (OG5,OG7,etc..)

Anyone know of any active developement regarding the 925V variant? Way too nice not to have root.

There is zero development.

Zero KNOWN progress. Who knows for sure though. King root might work for us one day or it might not.

There wasn't much development on my tmboile s5 either. What phones do have good development these days?

I guess mostly just Nexus devices.

I've stuck with my ATT Note3 on TMO, and TMO Note4. My son has a Sprint S6 Edge on TMO and it has surprisingly quite a bit of development. If I knew anything regarding locked vs. unlocked BL's I'd have a go with this 925V. Just really surprised at the lack of development for this device. Sucks!

Unfortunately, it seems that we've been left in the dark. Surely one of the many devs would have a thread going with some sort of progress update if any were working on it.

@spadz93 That's kinda what I'm thinking. Too bad. I use way too many root functions to even consider keeping my 925V. Really nice hardware either way. I'll probably look for a TMO variant.

Verizon sucks anyway. Worst service I've ever had. I liked T-Mobile way better. I have constant dropped calls, missed texts etc with Verizon.

I would pay good money to have some development for this device... without development, its useless... anyone interested? pm me =]

I wouldn't go so far as to call it useless... It's still a solid phone with decent hardware. Just because you can't root it and install custom ROMs doesn't make it useless. I'm more interested in a phone that works consistently everyday than I am the ability to push the hardware to the point of random reboots and overheating. Once I gave up root for 5.1 I've had next to zero issues with the phone and I like it much more.

Yea, my statement is a little exaggerated but no xposed is huge for me personally. I like to play with my phone and customize it. Without root and xposed, I can't do that like I could with my s4 so it bothers me

What upsets me is the fact that devs give up trying to root a phone if a solution doesn't come within a month or two, if the phone is the only variant that still doesn't have a root and it will take more effort than a few tweaks to do it. I've seen it over and over again with so many phones. If I knew how to even begin to look for a root on the phone and I had the money to buy phones that I could burn in the process, then I'd totally work at it.

what I dont understand is theres ppl with the Note 4 that are able to root 5.1.1 using King Root and no one has tried it on any firmware beyond OE2 for us yet..
I know one person said it worked for him on OF1 but need more to confirm before I update and update all my ROMs.
