SGH-I337 Unlocked Bootloader

Does anyone know if the method to unlock the bootloader for the galaxy s4 version SGH-I337 has been released yet? Something wierd happened today using goo manager. For the first time since owning the phone I was able to install a custom recovery where as before it said nothing was available? Does anyone know anything about this??

Just a page or so back and what everyone was talking about since. Please read before posting.

As for your CM10 flashing problem you should make a thread in Q&A

Thank you for your cooperation

so where are the people bumping this thread to make sure the hunt for what they want is done?i would have figured there would have been a lot more people posting they donated so scratch their pledge away, or the flip side of waiting for a "true unlock".

so where is everyone :P
[AT&T Samsung Galaxy S 4 General] MrPlNK:
Im here, pleased that my bootloader is still locked and we have loki :D
[AT&T Samsung Galaxy S 4 General] AxAtAx:
Damn good question, and I think that we have seen what the devs can do. Where do I donate. I am in. Because there is a true unlock. .u bet.

Out of thanks at the moment.

Donated to a charity per the unlock Devs request.
[AT&T Samsung Galaxy S 4 General] Planktron:
I'm gonna donate to Dan, but I'm po' right now. Truth is any dev who's worked on it deserves it too just for trying. The R&D thread is full of noobs asking which roms they can flash with Loki. Wtf? Bootloader seems hard to crack. I've read the azimuth security blog and these guys know their stuff. It's a shame that the rules for the thread are clearly stated on the first page and nobody follows them. Everyone wants a free unlocked bootloader so they can soft brick their phones and then post in the general section to get help unbricking...

Dans Loki is a fantastic exploit for those of us fortunate enough to already own an S4. The bounty is for an unlocked bootloader, but my money says flashing roms and kernels with a locked bootloader is close enough and damn good work.

I'm running Faux's kernel with TWRP, and rooted with motochopper. I put zero effort into it. I didn't create scripts or apps or recoveries or spend countless hours deciphering code. Devs did and they deserve something for it. If I ever met someone who changed my phone for the better and didn't even charge me, you better believe the beer's on me.

End of rant...

Btw shabby, I'm just across the bridge, lol
[AT&T Samsung Galaxy S 4 General] paleman27:
It's really been a mess which has been very difficult to sort out. To tell the truth, although some have tried, I think most don't want to touch it. However some people have asked me (some nicely, some obtusely) to express an opinion on the matter at hand.

Yes, some people have come forward and showed their appreciation for the good work that Dan did: the loki "work around". I bet nobody expected that: it works but is not an unlock; what a paradox! Some say is "the same thing" as an unlock. Some people have shown frustration, stepped away from the phone, returned it and move to another one. Others are waiting on the sidelines for a true unlock (like the X-Factor), some are using loki and some just can't be bothered. You also have the fans that loves Dan so much they just want to throw money at him for whatever reason they may see fit (Lol! :) ) So as you can see we have an impasse; instead of an "unlock" we have a "deadlock" (unable to reach an agreement or concensus).

So, is not a yes or no, black or white, or do or die answer. Does the "loki" work? Yes. Is it an unlock? No. So has the bounty been answered? Although we have a method (loki) that gets the job done, the door can not be closed and the case can not be filed because just as someone found a work around, someone could (even if it is Samsung or AT&T) , however unlikely, successfully unlock the bootloader. If it is unlocked, like the X-Factor, I will be with the first one in a horse with a posse rounding up the people that pledged :cowboy:. However, in the right mind, I can not express discomfort for those who pledged and are still waiting (for whatever personal reason) for an unlock. I can only encourage everyone that knows that this method gets job done, to step up and show their appreciation in anyway they see it fit.

What did I do personally? I donated to my favorite charity www.lilysangels.org Lily’s Angels is a non-profit organization dedicated to bringing awareness about Down Syndrome as well as raising funds to provide access to therapies for families with financial need.

I think is a very nice and selfless act of Dan to encourage those who feel compelled to donate because of his work in this forum, to do so to charity.

Thanks for your time to read this.

Regards,

paleman27
[AT&T Samsung Galaxy S 4 General] shabbypenguin:
how ever the person feels that made the pledge its on them, im not saying for them to go to one side or the other. i had however to go to the third page to find this thread.

this thread was filled with people posting non stop prior to the tools release, many people are grateful and are enjoying that (which is awesome :) ), i just expected more people to do one of two things, either announce their pledge is fulfilled and they got what they wanted etc, or keep posting in hopes someone would unlock it. i know a lot of people dont consider this worthy of the bounty, everyone is entitled to their opinion. i was just expecting someone who felt that way to still be waiting on a permanent solution to be posting so that people didnt forget.

[AT&T Samsung Galaxy S 4 General] fix-this!:
Loki is great and all but is there still plans to fully unlock this device?
[AT&T Samsung Galaxy S 4 General] hapticxchaos:
other than not having to provision the kernel with loki beforehand, what advantage does a fully unlocked bootloader offer? nothing, as far as i can see.
[AT&T Samsung Galaxy S 4 General] greenzone560:
There are even recoveries that auto-loki your ROM. In fact its better than bootloader unlock in my opinion because you can just Odin back to stock and ATT won't know **** xD
[AT&T Samsung Galaxy S 4 General] Red_81:
The vulnerability that loki exploits could still be patched. A bootloader unlock would be a near permanent unlock.
[AT&T Samsung Galaxy S 4 General] thacounty:
...until they patch it. They can always patch something. Whether it's unlock, Loki, or whatever. If you've already frozen the updaters they can't patch you unless you choose to take it in or take an ota.
[AT&T Samsung Galaxy S 4 General] hapticxchaos:
a bootloader update would relock it

i concur with the previous guy, now we can odin back and theyll never know (does the flash counter still apply here given the nature of the exploit?)
[AT&T Samsung Galaxy S 4 General] SysAdmNj:
This bootloader is still locked?

*exits thread*
[AT&T Samsung Galaxy S 4 General] spdwiz18:
ok.. Dumb ?..... if the GE S4 is vertualy identical to the branded S4 is it not possible to pull bootloader from GE S4 and put it on the other. Or am I way off on this? I'm a themer not a dev.
[AT&T Samsung Galaxy S 4 General] mg2195:
Nope :( if that was the case we could've done it with the T-Mobile variant or the sprint variant...both identical yet have unlocked bootloaders
[AT&T Samsung Galaxy S 4 General] spdwiz18:
OK. Thanks. Then the next question. Y not?
[AT&T Samsung Galaxy S 4 General] raitchison:
Depends on what the question you are asking is, if you are asking why you can't pull the bootloader from the GE S4 or from the T-Mobile variant I have no idea smarter people than me will need to answer.

If you are asking why is the AT&T version stuck with a locked bootloader there are a couple of theories:

One theory is that AT&T doesn't want to deal with bricked phones from people who F them up by hacking them but that doesn't really make sense to me because if you make it easy to hack the phone you reduce the chance that something will go wrong.

Another theory is that AT&T (or Verizon) simply doesn't want people to load a different OS for a variety of reasons including:

1. They don't want you to get rid of their copious bloatware.

2. They want to be able to force you to get a new phone (and extend your contract) in order to get new versions of Android and new features rather than extend the life of your current phone.
[AT&T Samsung Galaxy S 4 General] spdwiz18:
Sorry. I should have been more clear. I was wanting to know y we can't pull it from one on put it on another. But thanks for you're help and info.
[AT&T Samsung Galaxy S 4 General] sgs22012:
Simple answer is that it's a hardware /software issue....not something most novice folks should delve into Willie nillie

[AT&T Samsung Galaxy S 4 General] spdwiz18:
thanks.

I think of my self more then a novice but am far from being an expert. But, this still honestly does not answer the question or it might. That may be all it is(being hardware/software issue) No disrespect ment.

Are the devices so different in such a way, they cant pull it from one to the other? They are said to be "vertualy" identical. And I use the word vertualy lously. So again I ask Y cant THEY/WE pull the bootloader from one to the other? I am looking for a little more technical explanation.

Am I asking in the wrong place? maybe I should make my own thread.
[AT&T Samsung Galaxy S 4 General] scott14719:
Threads already exist about this. The bootloader on the I337 is tied to the hardware of the phone, if you attempt to "replace" it, the phone will become unusable.
[AT&T Samsung Galaxy S 4 General] pachi72:
So if they update the boot loader is has to run on stock software?
[AT&T Samsung Galaxy S 4 General] scott14719:
Any update will most certainly patch the LOKI exploit. Assuming it does, only the stock firmware will run until another exploit is found or the key encryption in leaked or released from Samsung.
[AT&T Samsung Galaxy S 4 General] pachi72:
Well I am running an AOSP ROM so I shouldn't worry right?
[AT&T Samsung Galaxy S 4 General] scott14719:
Worry about what? Loki being patched? No, AOSP shouldn't even be notified about stock updates. However, simply put, just don't take any OTAs unless Devs approve them first. If you are on stock Rom(s), freeze the files that handle the OTAs. There are several threads that outline which files need to be frozen.

The problem people like you (running AOSP) will face is if you need to return your phone for warranty repair or replacement. Right now, its not an issue, but most definitely will be in the near future when the LOKI exploit is patched.
[AT&T Samsung Galaxy S 4 General] s4shyam95:
I know that loki is a bypass, and not an unlocked bootloader,

So my question being,

What will be the advantages we have once we have an unlocked bootloader compared

to what all can be done with loki, as in, we can flash roms/kernels etc ...

Also whats the loki patch u guys are talking about ? Is it an update via ATT that will

not allow the loki bypass to work normally?

Thanks :)
[AT&T Samsung Galaxy S 4 General] WoodburyMan:
Loki is a patch. A patch that can and will be fixed by Samsung soon. Having a full unlocked bootloader means it's unlocked for life. No updates from Samsung can take it away.

For me. I don't care. I have CM10.1 installed and will likely keep 10.1 installed for as long as I have my phone. If I have a issue I can Odin back to MDL which is still able to be rooted and Loki'd then reload my rom and never update to a higher baseband.
[AT&T Samsung Galaxy S 4 General] s4shyam95:
Oh, cool thanks,

just a doubt ,

will sim unlock work with a locked bootloader ?

And is any one working on unlocking the bootloader for our ATT GS4 ?
[AT&T Samsung Galaxy S 4 General] WoodburyMan:
Sim unlock is a completely different function. There are ways some people have gotten their AT&T SG4's (SGH-I337) SIM unlocked by using a questionable hidden menu function and others by calling AT&T directly and saying they will be traveling and AT&T will unlock it. There may be a separate SIM card unlock utility in the future. Although calling AT&T and having them give you a SIM unlock code will always be the best and most official way.

I believe there are lots of people working on a AT&T SG4 unlocked bootloader as for all we know a new firmware that blocks Loki may come out the very next day.
[AT&T Samsung Galaxy S 4 General] Duffmantp:
I dont know if this will even help. But i figure I'd throw it out there. It may be known or just useless so you can flame me anyway.

After having been playing around in service mode to get my phone working i found some interesting stuff in there. One in particular.

[1] UMTS

[2] Version Info

[3] Secure boot status

There is some info in here, I dont know if it pertains to the bootloader or something else. But i figure i share what I found.
[AT&T Samsung Galaxy S 4 General] 82801BA:
I believe with loki you are stuck with custom roms while with unlocked bootloader you can load any stock i9505 rom to the phone. Since i9505 has a lot of different locales there may not be a custom rom available (ie. I want a TGY i9505 ZHUAME3 rom because some software that I want to use can be installed to that specific regional rom, but there's no custom, and therefore I don't root).

I have a feeling that AT&T locks the bootloader to prevent people using tethering and wallet?
[AT&T Samsung Galaxy S 4 General] scott14719:
As long as LOKI is used I9505 Roms can be used.

and both tethering and wallet can both be used. You can check the Development and Apps sections for more info.
[AT&T Samsung Galaxy S 4 General] 82801BA:
Really? I can flash .md5 files with custom recovery?
[AT&T Samsung Galaxy S 4 General] :
No? When did he say that
[AT&T Samsung Galaxy S 4 General] scott14719:
No, not factory or recovery files via ODIN (TAR), just via CWM or TWRP with flashable files. Unless it is the factory ROM that shipped with your device (SamMobile Firmware).
[AT&T Samsung Galaxy S 4 General] niceppl:
... easy just extract system and boot from the oden tar in linux. Make it a flashable..and patch the kernel.. and flash....

But how OTA with new version of bootloader can flash it?
[AT&T Samsung Galaxy S 4 General] mg2195:
The bootloader has certain software keys that get tied to the hardware, and when a new bootloader is put on the phone it also blows some qfuses that prevent older bootloaders from flashing

Unless you can get a hold of a tool to sign the bootloader, it is impossible to replace
[AT&T Samsung Galaxy S 4 General] JustinClayton0731:
Unlock Idea

Alright, Just had a few thoughts. I have a 16GB S4 on MF3 baseband.

Due to my upcoming deployment AT&T unlocked my phone at my request. Tried out the 8 digit unlock code he provided me and presto, it worked. They did not ask what baseband I was on or any other phone information other than my IMEI number. The AT&T rep also confirmed that regardless of future updates this phone will remain permanently unlocked. Thus I believe a reverse algorithm can be made from a skilled developer. Am I correct?

So if enough people posted there IEMI and unlock code who can make a script to generate an unlock code?

Also as far as the bootloader goes. MF3 locked it down. So can't a "fake update" form a developer potentially unlock the bootlader?
[AT&T Samsung Galaxy S 4 General] thacounty:
Carrier unlocked is completely different from this.

Not yet. What would be in this fake update? Unless someone breaks the boot loader encryption we can't unlock it. Seems to be locked tight this time.

[AT&T Samsung Galaxy S 4 General] jeboo:
The real problem is bootloader (BL) reversing really thins out the dev community. You have the following limiting factors:

1) Most devs stick with unlocked/vulnerable phones..so lets say devs with MF3/ME7(vzw) is 5%.

2) To truly do BL stuff, you need a jtag to unbrick. Devs with JTAG ~5% ?

3) BL reversing is very low-level, requiring experience with ARM assembly. And the programs to disassemble/decompile are extremely expensive. Devs with experience in this area < %5.

(My 3 estimates are probably gross overestimates.)

Thus you see the bottleneck..
[AT&T Samsung Galaxy S 4 General] sgs22012:
Auto Loki is best option atm but as mentioned here ARM and assembly language in and of itself is very versatile but archaic and thus the lack of dev support, best place to look for BLR support for mobile is a computer disk repair or recovery software groups...

I will donate $25 to find the bootloader unlock for this ATT version, its a must have, for those of us recently purchased a new S4, and had no option but to get the phone with MF3.

I am just so pissed at ATT for locking it down so hard. Why ? I don't get it. 99% of people don't root their phones or install custom ROMs, but for us 1% who do, why they gotta bust our balls and piss in our cheerios, and lock it down so tight ?

Even Verizon lately has better root and unlock going on in their new ohknes, which is shocking.
