[AT&T Samsung Galaxy Note 4] Shagerty:
I would like to go off of this guide https://javigon.com/2012/08/27/the-bootloader-understanding-modifying-building-and-installing/ and try to build a custom bootloader so that a custom recovery, and root can be achieved. I am unsure if this will lead to anything but I thought I would post the link in case anyone else would like to read into this sort of bootloader modification and give it a stab as well.
[AT&T Samsung Galaxy Note 4] Crimson Ghost:
This is definitely something worth learning but it isn't likely to help in this case since our bootloader is locked and any modification brings the unauthorized software message. You can build a bootloader all you want but you will not be able to flash it to the AT&T version of the Note 4.
[AT&T Samsung Galaxy Note 4] elliwigy:
I would like to add that messing with the BL when not experienced could result in a paperweight
[AT&T Samsung Galaxy Note 4] Crimson Ghost:
Exactly! Thank you for stating that. I thought I had said that but apparently I forgot.
[AT&T Samsung Galaxy Note 4] boofman:
Didn't realize the SM-910A variant does have a locked bootloader. I got a great deal today off of a used AT&T Samsung Note 4 in very good condition for $290 (I know, it could have been cheaper, but Samsung devices have a good resale value where I'm from)...had I known, I wouldn't have bought this one. The deal was pretty good to pass up on though, and I didn't have enough time to research on it.

I don't think AT&T would even bother helping us out, now with the Note 5 out and Note 6 soon, this device of ours may just be a little outdated for them to spend some effort on it.

I might as well give it to the wife, as she doesn't need root and is happy with stock. lol
[AT&T Samsung Galaxy Note 4] nemopsp:
Personally I feel that is on the high side. Because around my area I found two N910T3 which is the t-mobile Note 4 for $200 and yes they was unlocked. I've been looking around for any unlocked bootloader model my self since this N910A won't see a root.

I even found a dealer selling N910C model for $225.
[AT&T Samsung Galaxy Note 4] spexwood:
ATT wouldn't help us out because they locked the bootloader for a reason. They wanted the phone as secure as possible since the ATT Note 4 is involved in a US government contract. Neither ATT nor the government wants the phone to be potentially hacked.
[AT&T Samsung Galaxy Note 4] boofman:
Thanks for the information!

Well, it looks to me like we'll never have an unlocked bootloader after all, with the government being involved! Its now safe to say that there is no hope.

Security is a major issue, so this is perfectly understandable. Now, I will be avoiding AT&T Devices moving forward.

Yes, that's great! 200 bucks unlocked BL..but shipping and customs are gonna kill me for sure..lol

Samsung devices have ridiculously high resale value where I'm from, and getting a Note 4 for $200 would only be available from the black market.

Yes, I agree, N910A won't ever see root, with the AT&T government contract in place..so I might as well donate mine or swap it with an LG G3 that has tons of custom ROMs and kernels..
[AT&T Samsung Galaxy Note 4] Tmobilefan906:
Pretty much most T-Mobile bootloader's are unlocked.
[AT&T Samsung Galaxy Note 4] Android.Ninja:
Aren't all T-Mobile boatloaders unlocked. I was thinking they were but I could be mistaken.

Developers don't need no stinkin' signature!

If I've been able to help you, please hit the "Thanks" button. * ;)
[AT&T Samsung Galaxy Note 4] elliwigy:
i think even some of the new devices are locked even on tmo.. i think the s7/e is locked now

Possible Progress with OCR?

I'm not really sure if it adds anything to this thread, but I have the sm-n910a with the latest OTA, and on a whim I tried the OCR App, and it read my device as the below and says it can root.

[IMG="OCR SS"]http://i.imgur.com/1aHfjQ2.png?1[/IMG]
[AT&T Samsung Galaxy Note 4] nemopsp:
Well couple things about that picture you posted it's not even a Note 4 N910A model it's N900F model which is a Unlocked Note 3 and the F model has an unlocked bootloader already. Also another thing is its on 4.4.2 kitkat which you could just use TowelRoot by GeoHotz to root. And Note 4 released with 4.4.4 kitkat.
[AT&T Samsung Galaxy Note 4] iroot84:
I understand the difference in what the app detected, and that was my point. I found it odd that it supposedly detected my device that way, and considered it perhaps a far fetched possibility it could help the root efforts in some way.

This is my phone, which was detected as the other photo shows in my last post by the OCR App.
[AT&T Samsung Galaxy Note 4] Kyuta Syuko:
Not sure why it detected your phone wrong. Just tried it with my phone and OCR detected it correctly.
[AT&T Samsung Galaxy Note 4] gcodori:
Another reason why this forum is the BEST resource when it comes to accurate rooting information. Not some app that can't even identify your phone correctly.
[AT&T Samsung Galaxy Note 4] boofman:
How similar is the VZW Note 4 to ours? They've somehow managed to unlock their BL..
[AT&T Samsung Galaxy Note 4] elliwigy:
with a little research you will know lol. They are pretty different..

the way the BL unlock was obtained is Samung accidentally released vendor codes at which they were able to exploit in changing the retail N4 into a developer edition.

ATT doesnt have a developer edition so its not possible at this time.

You might be able to change the eMMCID but what to?

Or you might end up with a hard brick...

[AT&T Samsung Galaxy Note 4] boofman:
Thanks for that info..

Looks to me like it might be the end of the road for us then..

A while ago it looked like it was the end of the road for att and vzw and you see what happened, anything is possible.

I would compare our situation to the missile development. The note 4's that got rooted are like the U.S. And Russia. The att version is like North Korea but at least they don't give up

[AT&T Samsung Galaxy Note 4] quanqngbk:
No way to root this device at 5.1.1

Til now? There still is no way...
[AT&T Samsung Galaxy Note 4] YousKoose:
That's crazy I thought ounce the Verizon note 4 was rooted it would work for at&t variant aswell, that's why the bounty thread was for both variants. Is anyone working on root for at&t?

# I heard team Yemen has a root for the at&t variant and are working on realising it.
[AT&T Samsung Galaxy Note 4] amsgh:
I've heard that too for the last 6 months!

[AT&T Samsung Galaxy Note 4] exxTErno:
I´m pretty sure that all the good and great developers able to unlock this bad boy have already moved up to another device, I really don´t think is that impossible. Too bad, such a great and beautiful device with no root nor MM.
[AT&T Samsung Galaxy Note 4] elliwigy:
They said that about the Verizon variant also
[AT&T Samsung Galaxy Note 4] exxTErno:
Yeah, I guess you´re right but is inevitable to loose faith after all this time, will hold on to it a little longer and let´s hope we can get a nice sorprise some of these days.
[AT&T Samsung Galaxy Note 4] Crimson Ghost:
I know if I sold mine a root would be released 5 minutes later.

[AT&T Samsung Galaxy Note 4] Samsung8600:
Are all of you guys with this version of note 4 are using 5.0.1 ?

I have it too and I can't believe it won't update
[AT&T Samsung Galaxy Note 4] boofman:
I check this thread about 5 times a day, hoping Samsung / ATT makes the same mistake VZW made, and release the keys so our Devs can root this thing. Lol
[AT&T Samsung Galaxy Note 4] elliwigy:
except thats not what happened lol. they released "vendor codes" which essentially to my knowledge works for ATT as well but ATT doesnt have dev editions so theres nothing to change the CID to that will allow it to be unlocked.

Basically, if they had an att dev edition note 4, youd be in luck but it just doesnt exist.

I assume it wont take a Verizon branded eMMCID which is why its not possible for you folks.
[AT&T Samsung Galaxy Note 4] boofman:
So, unless ATT unlocks the bootlader themselves, there's just no any other way then, right?
[AT&T Samsung Galaxy Note 4] elliwigy:
not with the vzw method.. maybe something new will come up
[AT&T Samsung Galaxy Note 4] sb0:
So I might as well find an unlocked T-mobile version ;\

What a shame - I should have done my research first...
[AT&T Samsung Galaxy Note 4] amsgh:
I've been thinking the same thing... I just don't want a used phone my att note 4 is mint like new.
[AT&T Samsung Galaxy Note 4] sb0:
I figured I'd keep my new ATT note 4 as a reliable phone and get a used t-mobile version to hack out and use as a backup (or maybe a used galaxy s5).
[AT&T Samsung Galaxy Note 4] boofman:
I also have a G3 Beat with CM13, which I use as a second phone for a different network and which I also use as a Music Player as it has Viper4Android..

The Note 4 sure is great, even with Touchwiz and all, so I can live with it being stock..also, even if we did have an unlocked bootloader and root, I am not sure if I'll want to move away from Touchwiz without the S-Note and other S-Pen stock features..maybe a stock-based ROM and a Custom Kernel will do..having said that though, I would've loved to have root on it so I can remove all the bloatware and install Viper4Android on it as well..
[AT&T Samsung Galaxy Note 4] sb0:
Touchwiz is actually one of my favs.

Root would be great for removing bloatware and freeing up some device storage. Root enabled apps like adfree android and root file managers of course goes without saying.

I'm a linux guy and it feels so restricted not being able to have full access and control over my device.

Terminal app is almost pointless [emoji36] [emoji17] [emoji35]
[AT&T Samsung Galaxy Note 4] boofman:
Same here..I'm a Linux guy, too! I hate the fact I'm being locked down..
[AT&T Samsung Galaxy Note 4] Danny 0311:
When my Note 4 contract is done, so am i. Back to Nexus for me. The new Nexus, or a used 6P is better than getting locked down.:p
[AT&T Samsung Galaxy Note 4] marcimix:
I wanna see devs I wanna see devs workin' on the N910A

[AT&T Samsung Galaxy Note 4] rydia:
Just picked up a SM-N910A at a great price, was thinking it would be cool to throw a custom rom on it.....

Until now...

:(

Here's to hope I guess.
[AT&T Samsung Galaxy Note 4] boofman:
Same here..

It's a good phone nevertheless..

It could have been a great phone even without any custom rom on it, just root..

All I want is to be able to turn on the mobile hotspot.

Foxfi works great for me and my unlimited data.
[AT&T Samsung Galaxy Note 4] spocko:
Looks like you have Verizon. I don't think Foxfi works on AT&T.
[AT&T Samsung Galaxy Note 4] Demonshorts:
Worked fine on At&t for me..
[AT&T Samsung Galaxy Note 4] Crimson Ghost:
It doesn't work with AT&T for Wifi. Usb works fine and Bluetooth works but is terribly slow.
[AT&T Samsung Galaxy Note 4] Demonshorts:
I beg to differ, I used Foxfi on my note 3 and note 4. On wifi, without a hitch. Both are AT&T variants. That was about a year ago, unless the app has changed; it should still work.
[AT&T Samsung Galaxy Note 4] Crimson Ghost:
I used it on my Note 3 and it worked fine while I was on JellyBean. It may have even worked on KitKat but it does not currently work on the Note 4 with 5.1. I believe the issue is that I have the old unlimited plan. If you have a regular plan it would work fine.
[AT&T Samsung Galaxy Note 4] sazon goya:
Again not sure if a TrustZone exploit will get us closer to having root on the AT&T Note 4 but laginimaineb has put a full write up of an exploit on his blog: bits-please.blogspot.com/2016/06/trustzone-kernel-privilege-escalation.html . From looking at earlier Note 4 posts about the booting process it looks like it could help but my programming skills aren't anywhere near good enough to know for sure.
[AT&T Samsung Galaxy Note 4] boofman:
He does claim that this exploit should allow modification of bootloaders..

maybe some of our master Devs can look into this? This might be our only hope for a bootloader unlock, unless Samsung / ATT has patched this already..
[AT&T Samsung Galaxy Note 4] Tmobilefan906:

That's available on 5.1.1. Didn't u update?
[AT&T Samsung Galaxy Note 4] jboucher614:
Has anyone tried Kingroot recently on the N910 (AT&T) with all the updates? Just wondering if Kingroot has changed anything and made it at least a bit more stable, or if the security updates from AT&T have made it worse/more likely to brick?
[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
We'll just move further down the list as new phones come out .
[AT&T Samsung Galaxy Note 4] irgb:
Kingroot

Just upgraded to the final update 5.1.1, kingroot would go to 35% tried 4 times.

All I want is to use foxfi. According to them I have to go to 4.2 for the note 4, is there any way to do that?
[AT&T Samsung Galaxy Note 4] boofman:
Don't try to force root, you'll brick your phone. We'd still need an unlocked bootloader to do that, and there doesn't seem to be any way to unlock it.
[AT&T Samsung Galaxy Note 4] boofman:
Hi guys! Looks like S7 from ATT gets root!

http://xdaforums.com/att-galaxy-s7/how-to/g935a-root-t3410403/page1

They've somehow unlocked the Bootloader and bypassed the encryption..maybe we could replicate what they did?

UPDATE: asked the guys from the S7 thread, and they told me the EngBoot was somehow leaked to them.

Looks like we're still stuck.. *sigh*
[AT&T Samsung Galaxy Note 4] Dullaz:
So close yet so far. Waiting on this root.
[AT&T Samsung Galaxy Note 4] nemopsp:
I call all bull****. I've said it before and I'll say it again. They could root this phone with all the exploits we have now, but the people with the knowledge have all moved on especially after N910V bootloader unlock. No one is going to waste their time. But it's okay last Samsung phone I'll buy. I'll be buying me either iPhone or Nexus or Oneplus.
[AT&T Samsung Galaxy Note 4] MeganFox1:

[AT&T Samsung Galaxy Note 4] Zeal415:
.... DAMMIT, Just got this phone today, I figured it'd be rooted by now. Any chance this phone will be rooted in the future? Also, should I hault all upgrades?

I am not on AT&T, im on MetroPCS and the phone is unlocked. Anyway to remove the bloatware atleast?
[AT&T Samsung Galaxy Note 4] boofman:
Sad to say but there isnt any root progress.. though you can disable some apps without root, but you just can't remove them..
[AT&T Samsung Galaxy Note 4] Zeal415:
Thanks for the reply, at least the stock I'd not bad. Think updating to 6.0.1 would be problematic for potential roots?
[AT&T Samsung Galaxy Note 4] boofman:
I'm not sure, and it's a safe bet nobody knows for sure. Personally, I've not updated for the odds that it may hinder the chances of getting root, with the security updates and all.

I wanted to have root for the following reasons:

1. Remove bloatware

2. Viper4Android

3. Xposed modules since I want to remain stock because of SPen features but I want to tweak some visual elements

But I've learned to live without root, as I've a LG G3 Beat that has CM13 on it, so my flashaholic and tweak desires can be fulfillled there..lol
[AT&T Samsung Galaxy Note 4] Armorer2779:
You can install Package Disabler Pro and it will allow you to disable a lot of the bloatware. Just make sure you know what you are disabling. My brother bricked his note 5 after we were trying to help him make it run smoother. He lucked out and somehow got it to let him reset it after an hour of trying different resets. The problem was caused by a combo of him having power saving on and disabling something that power saving had to have on.

Ive been running the app for quite a while on my note4 and have had great luck, but I dont run power saving because Ive got a zerolemon battery.
[AT&T Samsung Galaxy Note 4] boofman:
I'm actually using Package Disabler myself. What I'd like to do though is to remove some of them entirely, since they are just taking space without them being used.

I dont use Power Saving as well, and instead use Greenify (without root, of course) and set it up that it puts some of the apps to sleep when the screen is off faster than what Doze can do.

T-Mo Motherboard

I was having all kinds of problems with my ATT Note 4: No more fast charging, sim slot occasionally dropping my SIM card, overheating, etc.

I suspected I needed a new motherboard. I went out on a limb and ordered one for a T-Mobile Note 4, and it was already unlocked. $150 on ebay, IMEI came back clean.

Here's the BIG ONE: It fits and works. I'm now running a 910T motherboard in a 910A shell.

Root, here I come. ROMs, here I come.

Just Do It.
[AT&T Samsung Galaxy Note 4] Zeal415:
Let me know how that works for you. Also what could are you using now?
[AT&T Samsung Galaxy Note 4] draagyn:
Up and running on Maximum Overdrive MM rom. Rooted, etc. Man, I missed this!
[AT&T Samsung Galaxy Note 4] killaj419:
So it really works? I would think the frequency bands would be different for service.
[AT&T Samsung Galaxy Note 4] draagyn:
There are differences on the bands, but enough in common I don't effectively notice a difference. Everything is good and smooth.

The only thing I notice may not work is wifi calling. The icon on the notification bar is green, but under settings, there's a message I don't have the proper sim card. It's not a big deal for me, since the area I live and work is LTE saturated.
[AT&T Samsung Galaxy Note 4] killaj419:
Nice to know. Over here it's att dominant. Not even Verizon has good service here.
[AT&T Samsung Galaxy Note 4] Zeal415:
Ha, I unlocked my at&t note4 onto metropcs network, the service has been good, with the exception of getting lte sign and only getting 1mbps download, couldn't even read the upload. But that rarely happens, and I am on the road and cover a really large area for work.

I considered switching to cricket since they use at&t towers, but metro gives me unlimited lte data, at $55 a month with 8 gb of hot spot. That's too good of a deal, and I hardly ever have an issue with service, streaming twitch and youtube while I drive around all day.

Might be worth getting the mono to eliminate the few times I actually get show data, but it happens so rarely. If if I should risk ****ing up a great phone for the 1x a week slow data lol. Thanks for the updates though.

Thanks in advance,

[AT&T Samsung Galaxy Note 4] draagyn:
It was an eBay item, so YMMV. There are two variants of the TMO Note 4, the T and the T3. I bought an unlocked T.

I bought mine from partlpgics, but there are several other sellers on ebay with the same item. This was the whole motherboard - board, cameras, sim/SD card reader.

Be careful taking apart your phone. Plenty of opportunities to destroy your screen.

A bit wrong here with newer phones. Look at the Galaxy S7 and Note 6. Locked bootloader now even with tmobile. Tho they did manage to root the Galaxy S7 because since all models are lock. It made a real developer look at it. As N910A model never had anyone to really look at it. There are 2 major bootloader exploits for the Snapdragon 805 chip with eMMC and Trust Zone exploit.

Plus with Android 7.0 coming an now enforcing strict boot only. Which right now Samsung device have away around it by disabling dm-verity with custom kernel.

Why don't u all just buy a T-Mobile note 4? All u have to do is pop in the att sim card.
[AT&T Samsung Galaxy Note 4] nemopsp:
Why would I waste money on another Note 4 ?? Just as most people already have moved on to a newer device. In about 3 month I'm upgrading ? But I'm either buying the new Nexus or Oneplus 3 off contract new than I'll just buy the iPhone 7 with AT&T with my upgrade.

I'll have best of both worlds this way Android with unlocked bootloader an full root. Plus Nexus devices gets a new updates every month. Also I'll have an iPhone 7 64gb with iOS 10 and I've been keeping up with the jailbreaking community which they did just release a iOS 9.3.3 jailbreak. Another developer has iOS 10 beta 3 jailbroken already. The jailbreak probably won't get released til February next year at latest.

I've had my Note 4 for almost 2 year an it's still on 4.4.4 kitkat and no root. Plus I can only update it to 5.1.1 not even 6.0.1 yet.
