He works for Google now, would not be in his interest to release information on a vulnerability publicly with a job like that. Or atleast my thoughts are that it wouldn't.

Really surprised by that hadn't seen much on the forums about it so assumed he was still there. Well in that case he might definitely be interested as long as Samsung isn't going to sue him lol.
[AT&T Samsung Galaxy Note 4] yamaha_wins:
I don't think samsung would have any legs to stand on in a lawsuit. It isn't illegal to root or jailbreak your phones?. Geohot has never once said root your device and you'll be able to use pirated apps, etc. I think Sony already tried suing him..
[AT&T Samsung Galaxy Note 4] eklipz3:
I think the only legs they would have is if it was something he was involved with and he leaked it. But correct me if I'm wrong.

He probably had to sign an NDA... More likely that's why he's not even active I any development, specially related to Android, same thing happened to [MENTION=1333111]comex[/MENTION] the one that made the one Swipe jailbreak thru safari after he went to work for crapple...
[AT&T Samsung Galaxy Note 4] XVIravenIVX:
Sony did sue him over the PS3 jailbreak. You would have to Google it since I can't post links but its part of why on one of the sites he had up (I think for a iOS jailbreak) it just completely bashed Sony and said not to buy their products since they sued him. To add to this quickly no it isn't illegal to jailbreak or root phones even though apple wishes they won that legal battle.

Windows 10 may be the answer

Last time I posted some got into a little back and forth. Let's see what happens now. Hope this is of use for root.

I recently, like many others, updated to Windows 10. I noticed an app called Phone companion.

This app seems to have the ability to sideload to your phone.

w w w . androidcentral.com/windows-10-phone-companion-and-android-do-you-need-it

There is a handy link to the File Explorer app, if you want to go digging around the user-accessible file structure of your phone. (That is, what you can get to without root access.) But then again there's also a handy File Explorer link in the Windows 10 toolbar. The "Import photos and videos" link opens up the Windows 10 Photos app, but it didn't manage to automatically find the DCIM folder on our GS6 edge.

Anyway just thought I will give this a mention and hopefully the DEV's can give a look and just maybe figure it all out.
[AT&T Samsung Galaxy Note 4] elliwigy:
probably no use if it can only access normal file system (non system/root priveleges)
[AT&T Samsung Galaxy Note 4] graydiggy:
I feel like it would be no different than Kies... Same principle. Just a companion program for a phone.
[AT&T Samsung Galaxy Note 4] jocarog:
Stagefright? Anyone?
[AT&T Samsung Galaxy Note 4] yamaha_wins:
Says my note 4 is also vulnerable
[AT&T Samsung Galaxy Note 4] linkdead13:
The PoC for Stagefright was released yesterday at BHUSA2015. The mediaserver that is exploited runs at root level. In a conversation with Jduck in theory it would be a very viable means of rooting alot of phones.

[AT&T Samsung Galaxy Note 4] slothdabski:
Even if this could lead to a root method for lollipop, Im not sure if it would help disable the WP on the locked BL which is what's really holding back this device
[AT&T Samsung Galaxy Note 4] psyciatrichelp:
Do we actually know if WP is enabled on 5.1 on the note 4? I mean we know its on 4.4.4 because we have root and it keeps reverting. Maybe, just maybe, WP is not enabled on 5.1. maybe its more like the s6 and once rooted it will be perma root. Won't really know till 5.1 is rooted on note 4. But nice to think about. I am hopeful.
[AT&T Samsung Galaxy Note 4] slothdabski:
Anything is possible but i doubt ATT is lowering the security on the bootloader, if it even gets changed at all when the lollipop OTA is pushed through
[AT&T Samsung Galaxy Note 4] psyciatrichelp:
WP wouldn't be in the BL though. The BL is just what allows the kernel to run. WP would be in the Kernel itself. ie it mounts a partition to ramdisk and only allows changes to the ram disk and never saves them. the boot loader tells the device where to look and how to boot and checks to see if the kernel is properly signed.
[AT&T Samsung Galaxy Note 4] slothdabski:
Thanks for the info!!! That makes sense and increases my optimism that we'll see a (perma)root. Im seriously thinking about ditching my ATT note 4 for another device due to lack of root and custom ROMs, but may try to hold out longer to see what happens!
[AT&T Samsung Galaxy Note 4] yamaha_wins:
We currently don't even have a temporary root for lollipop, it could possibly get that if not a permanent root.
[AT&T Samsung Galaxy Note 4] psyciatrichelp:
I am extremely optimistic. This will be the last AT&T branded phone I will ever own. only going with unlocked BLs in the future. but I love this device. And if Stagefright does indeed lead to rooting 5.1 that will open a whole new set of opportunities for the devs here. It is just a matter of time.
[AT&T Samsung Galaxy Note 4] slothdabski:
Sweet, I like your confidence! This device has def been a learning experience to avoid carrier phones. When i have an device upgrade in April, I'm just going to buy whatever device seems to be in the most demand, immediately sell it, and buy something else.

EDIT:

Also, can you link to a DEV thread that is working on this? I'd like to follow to see if progress is made, plus I could probably learn a thing or 2 from reading it!
[AT&T Samsung Galaxy Note 4] psyciatrichelp:
I am currently following this thread and http://xdaforums.com/note-4-att/general/thinktank-t3107629. the main dev thread was closed a while back. but there are several devs that pop up here when they can and have new info to report. But they got a lot going on in RL so they have been less frequent this summer but they are definitely doing what they can. Just got to be patient and put up with all the off topic posts. I know Hex in particular was focusing on WP. but he has a lot going on at the moment.

Certifi-Gate scanner by CheckPoint itself (from Google Play) shows my Note4 (lollipop) is vulnerable.

Question... has anyone before ever on other devices cracked Write Protection? Is it possible with locked bootloader or not even in a dream?
[AT&T Samsung Galaxy Note 4] nemopsp:
Other devices have gotten around the WP, devices such as HTC and LG (fastboot) tho I don't kno to much about thoses devices so I can't give out much info

Tho I can say No Samsung phone has had this WP and as of right now we are unable to find a way around it sadly :(

Hopefully soon someone will find a exploit for it! I hope with new phones coming out the community / developers don't just drop this phone... Hopefully someone will crack it an work on it
[AT&T Samsung Galaxy Note 4] thepianoman77:
Oh. I see. For some reason I thought ending always had wp.
[AT&T Samsung Galaxy Note 4] nemopsp:
Ending?

But that is why pervious device like Galaxy S3, S4, S5 was all rooted same with Note 1, 2, and 3 also

tho Note 3, and S5 was abit harder

And now Galaxy S6 and Note 5 dropped the Snapdragon chip and use Samsung Exynos 7420 which is why they have a permanent root b4 Note 4
[AT&T Samsung Galaxy Note 4] elliwigy:
not exactly correct.. the note 4 has been rooted.. WP is not set up the same in any of the other galaxy devices as it is in the note 4.. has nothing at all to do with root.. they could have very easily used WP in the s6/s6e but its not present as it is on the Note 4
[AT&T Samsung Galaxy Note 4] jocarog:
Blackhat has been interesting this year and it looks that we are vulnerable to certifi-gate as well...
[AT&T Samsung Galaxy Note 4] nemopsp:
Obtaining root is not the issue...

It's the Write Protection on the kernel and since it's locked bootloader, we can't modify the kernel into a custom kernel with Write Protection disabled...

[AT&T Samsung Galaxy Note 4] fbauto1:
If we can create a service that roots the device, and mark that application as a trusted application through Certifi-gate, then the rooting app will run at startup so device gets rooted every time, mimicking a perma-root.
[AT&T Samsung Galaxy Note 4] nemopsp:
Issue with this would b the fact that over time we would still lose root just in the matter of how fast will it take for the WP to kick in
[AT&T Samsung Galaxy Note 4] fbauto1:
No. Since you can install a remote support tool like Communitake, and exploit Certifi-Gate from there. The rooting app itself is valid as far as Android goes.

If we could load our own kernel hypothetically could we bypass write protect at that point? If so I have an idea that might work.
[AT&T Samsung Galaxy Note 4] zxz0O0:
Ever heard of kingroot? That's the vulnerability they use.
[AT&T Samsung Galaxy Note 4] elliwigy:
the BL is locked preventing any kernel outside of a complete stock kernel from being flashed
[AT&T Samsung Galaxy Note 4] Surge1223:
My goodness, when you download the kernel source there's a platform.tar.gz along with the kernel.tar.gz. The platform.tar.gz contains a Samsung vendor dir. This would go in $android_src_dir/vendor and there's source for the write protect in their vendor dir along with the actual kernel driver source for it in in $KERNEL_SRC/drivers/md/

The source is there. IIRC it hashs against itself on every boot to verify but if you could overwrite mem temporarily who knows, remember some kernel mem is cached through reboots.
[AT&T Samsung Galaxy Note 4] Cave Canem:
Or can someone challenge a blackhat (with a sizable bounty, perhaps) to break the WP problem with the current root progress...

Or even find means to circumvent bootloader lock on these devices?

(With all of us, for future reference, forever buying unbranded, unlocked phones ATT and other carriers cannot lockdown with their bloatware...)
[AT&T Samsung Galaxy Note 4] elliwigy:
i tried with some kernel devs over on the tmo forum with my vzw s6e and there was no way to get it to flash.. unless of course they didnt make it right lol
[AT&T Samsung Galaxy Note 4] scottjoshuac:
Ksplice

So I'm not referring to flashing a new kernel. My idea is to port ksplice to Android. Ksplice allows you to make modifications to a linux kernel and apply the changes without rebooting the computer. If we could get Ksplice to work technically couldn't this be a universal way of bypassing write protect once temp root as been achieved?

[AT&T Samsung Galaxy Note 4] graydiggy:
Temp root has been achieved. Doing soft reboots is the work around that keeps root but it's only a matter of time before WP catches something and forces the phone to do a full reboot.
[AT&T Samsung Galaxy Note 4] scottjoshuac:
I realize that temp root has been achieved thanks to kingroot, I was just saying it could be beneficial to other devices too.
[AT&T Samsung Galaxy Note 4] boxerlover02:
Kingroot works? I just want to be able to mirrorlink with my headunit. If I get root I can spend the 30 on the app that makes it work
[AT&T Samsung Galaxy Note 4] Nemo Aeternamn:
No, but if you look further down. There's another vulnerability in the kernel,that's in all Linux kernels. Which would probably be a better idea to exploit.

You don't flash a new kernel, that would never work. Modules are possible if you can overwrite the check for secure modules in the current (booted) kernel.

Bootloader possibility

Just a thought.

My son recently got the Galaxy Core Prime on T-Mobile.

I activated the Developer Mode and when you go into Developer Options there is a option to unlock the bootloader.

Can it be possible that option exist on the Note 4 but is hidden some how. Just a thought.

Just throwing ideas out there and just maybe it might light up the light bulb.
[AT&T Samsung Galaxy Note 4] elliwigy:
theres ways to unhide it but it wont do anything after that

[AT&T Samsung Galaxy Note 4] graydiggy:
That doesn't unlock the bootloader. It only allows it to be unlocked. We would still need the proper keys to do so.
[AT&T Samsung Galaxy Note 4] linkdead13:
What I know about Certifi-gate exploit from ripping apart the scanner apk. Is that At&t remote support is the system app that is exploitable apk on the NOTE 4 for At&t. The other thing I have learned is that Attremotesupport is created by Communitake. So I'm guessing it would be exploitable by sms for root control.

PIT File

I've noticed that sammobile has nothing for the AT&T Note 4, I've lightly searched for the PIT file for this phone, but haven't come up with anything. I'm guessing the PIT file is still being held hostage by Samsung, so if we do get a copy of the PIT file, could it be used at all to figure root, since that file pretty much wipes everything, repartitions, the lets you install android OS? Just curious, because my thought is since it can do that, can you inject some code that either disables WP, lets you modify WP, or lets you access bootloader, you know something along those lines.
[AT&T Samsung Galaxy Note 4] elliwigy:
to my knowledge pit is just like any other file within the tar and most likely signed as well.. it might fail to write altogether if not properly signed or is modified

So anyone wondering how long it will be before the note 5 gets permanent root?

"Die and be a hero? Or live long enough to see yourself become the villian?"
[AT&T Samsung Galaxy Note 4] bobloblaw1:
Has that Exynos exploit from the s6 been patched? If not, pretty much instantly in all likelihood. Then the devil is in whether the note 5 has a similar verity implementation.

But can we try to keep conversation on the note 4?
[AT&T Samsung Galaxy Note 4] TechBSwift:
Probably sooner than the note 4 because it runs the same processor as the s6/edge so the community is much bigger. I don't think the note 5 will have write protection since the s6 didn't.
