Sounds to me like dude just ran the last update. Wondering what that's about though. I won't be updating, so who will. LOL
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Android_noob17:
This is what he said happened.

"Reading Reddit. Went to scroll down and got no response. Hit the back button. Nothing. Home button. Nothing. About 10 seconds and the device restarted. Then splash screen. The splash screen actually showed up twice. Like the device restarted twice in quick succession. After the splash screen it booted up like normal."

How would he check to see if his bootloader is unlocked or if Knox is tripped?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] pantmunu:
he said he had the unlock thingy at the bottom with custom written somewhere. software updates dont do that .. so lets see. i asked him to come over here and discuss it over here . might help us
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Far2great:

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] pantmunu:
just asked him to over to xda .. lets see
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] mrbigdrawsz:
So if that's the case, if we do get unlock, does it just reboot on its own?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] MegaNoob:
I believe unlocking the bootloader wipes the phone also. So if he still has all his data it's probably nothing. Most likely he just updated and didn't realize it lol
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] pantmunu:
Nope. Not at all.

This has been happening since the S4.

Any modification (in your case, it seems a malicious one, or some attempt at compromising your device by an app/website) that makes any modification to not only /system, but also /data, some sysfs probes, and files in /persist or /OEM (these last two likely being the ones that whatever crashed your friends phone modified) triggers a flag that causes the unlocked padlock.

A fresh ODIN flash of your current firmware will reset the flag.

Your bootloader is still locked, I promise :/

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Freddit-:
My T-Mobile S7E just automatically restarted and showed an interesting splash screen.

I posted this on /r/Android and I was told to repost it here.

I was using Relay for Reddit, and suddenly the device stopped responding to input. About 10 seconds later it shut off and restarted. Normally there is a splash screen that says "Samsung Galaxy S7 Edge powered by Android". Well this same splash screen came up, except there was an unlocked padlock icon in the center with the word "Custom" underneath that icon.

The device booted up like normal and works like normal. The splash screen does not reappear in other reboots or hard reboots. This is the same icon I saw when the bootloader on my Nexus 5 was unlocked.

If there is any useful information that I could possibly provide, please be SPECIFIC about what information you want, and how to get it. I am NOT experienced with this stuff. My experience extends only so far as to have rooted my Nexus 5 for special app permissions.

I do not currently have access to another phone to take pictures of the bootloader screen that someone on Reddit requested, but I'll try to get something soon for it.

Hope I can help in some way.

IF YOU NEED INFORMATION BE QUICK WITH YOUR REQUESTS. This phone is being sent back to T-Mobile Thursday afternoon. (tomorrow) I'm exchanging it for a new one (under exaggerated complaints to get a sealed one to sell on Craigslist so I can just get a Nexus 6P instead and pocket the difference)
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] dazednconfused:

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] evilpotatoman:
Here's where it's at, but first a few notes and thoughts;

A) Even after upsetting dm-verity, the system remained somewhat stable*

*The only issues I see are the system:custom message, an unlocked boot logo, and that the stock installer refuses to install anything but FOTAs or a sec_csc.zip flashed on the CACHE partition. If cleared, the system boots up normally​

B) It's extremely difficult to reverse dev this device - Every piece of secure-trust-knox-DRK-verity-crapola increases the chance of a misstep and ending up with a really nice IOT brick. Because of all this security, looking for buffer overflows and random execs would take ages. I focused on stupid programming mistakes, sifting through log files, much like I did when developing the original Note 3 recovery method.

C) The HOME_CSC partition file that seems to fail typical odin flashes -- It sets something permanent, like kind of hard-coding the verity keys. During my testing, I flashed one only to later realize that my CSC was then hard-coded to Chinese branding. Before that flash, I could mess around with the branding at will (and subsequently write to the system partition). It was only after I flashed that CSC_HOME that dm-verity actually failed. In short -- I had root BEFORE download mode labeled my system as custom. I flashed HOME_CSC, dm-verity then failed when I changed the CSC following the hard-code.

I have yet to fully re-create my EFS partition, and sent it to someone who wears darker hats than I for a fix. Because I won't have the phone for a while (at least 2 weeks), I've decided to give a brain dump in hopes that someone can pick up where I left off.

PM me for additional details, but the following should get better devs searching for a more stable method.

sec_csc.zips (found in cache.img.ext4) can be used to modify the system partition, and the partition itself isn't signed. Those zips also set the region.

*A particularly interesting csc zip exists for the G9300's CSC file.....

Odin happily flashes specific "partitions" individually, so piece-meal it out.

nand partitions can be written to while still failing in odin (but system.img is signed in 2 places, so fyi)

The exploit leverages those download-mode/recovery, plus the stupid programming error found below:

on the stock firmware, there's a boot script that calls a missing binary, which is a perfect -in- for the su daemon.

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] UnixSlayer:
This could actually be Samsung's way -in- to unlock, or to inject their programming to make changes. But it could also be the -in- where the encryption keys get access when a request is made on the Secure server.

Good thing for Root Cloak, but that depends on Xposed and I think Samsung/Android Pay still don't work with Root Cloak.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Shane-Man:
I wonder if the OTA update has fixed the missing binary during boot. I'm assuming that would give us a clue as to whether or not that's Samsung way in as UnixSlayer has mentioned
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Alarand:
Just to clarify, are you saying all HOME_CSC files seem to have this quality to them or just one that you flashed?

I'm worried now because I've done a couple stock reflashes and I can't remember for the life of me if I used HOME_CSC or the regular CSC

edit: potentially only affects multi-csc roms so tmobile version could be fine

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] mocsab:
I like the way you think! I almost got the flat - glad I ponied up and got the Edge - it is a beautiful phone - just need to get this thing unlocked - now that I have red about Crum from China - (was that what it is called?) either someone will find a way to use that to unlock or Samsung will release that for the TMOBILE S7 here - they appear to already have the process - and doing it that way allows them to get a record so they can cancel warrnety for anyone that uses it - that seems probable to me...

(edit -red about crum from China - seems like a Freudian slip - should read - read about crum from china - lol)

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] chiikko561:
Why do you care what bootloader it is that makes you get unlocked? I don't care what bootloader it is as long as somebody figures it out I'm paying.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] :
Because that isn't unlocking the bootloader. It's grabbing an image from a phone with similar hardware and uploading. While appreciated, it's not something I'd choose to donate for.

EDIT: I don't see why people have a problem with this. I can choose to donate my money the way I want to, and if a group or single dev gets any money for it, that's great. Don't criticize me for opting in and supporting a bootloader bounty.

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] jbfountain:
If someone can figure out how to unlock the bootloader I think it will most likely work for both S7 and S7 Edge as well as all carriers. I think the only way even Samsung could control which carrier devices with a tool they release would be unlockable is with a online method by IMEI or MID.

How does something like root cloak work? I guess for the matter I may ask how does a root request work?

I always just assumed if an app asks for root, supersu (or whatever you have) can deny the request. How would denying a request for root be different from root cloak? How would an app like Samsung / Android pay still be able to tell behind these curtains that the phone still has root?

Just found out that if anyone wants a unlocked bootloader, you can get upsie insurance and file a claim. They will give you an international version as a replacement if you ask. It is only 50 dollars and a 25 dollar deductible for every claim. This way you get cheaper insurance than tmobile and an unlocked bootloader.https://upsie.com/smartphone-warranty/

Yes so bricked that the only thing that recognizes the phone is Qualcomm QFIL, but it can't load anything because the phone won't respond.

I'm thinking that maybe with the Qualcomm software we maybe can get a modified kernel or bootloader past security since its not checking Samsung's security.

Is anyone familiar with Qualcomm's QSPT - QFILL that also could make a modified kernel and or bootloader to flash with it since it bypasses ODIN?

It's been used before on other phones, but I've already bricked one with ODIN, and eventhough I feel more confident withe the QFILL method I'm kinda gunshy at the moment.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] brendan802:
I should have tried qfil too but didnt. I bricked through odin and now with what evilpotatoman said it makes sense why it bricked. Mine showed as qusb bulk and odin wouldn't recognize it even changing the port to the correct one.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] jbfountain:
Yeah mine wouldn't boot at all it would just show up in device manager under ports, but it was too late to do anything with QFIL. Now it's recognized by QFIL and is ready to flash stock files. If someone with much more talent than me could modify the stock files to unlock the bootloader I might even be tempted to try to flash through QFIL. Although I already donated $800 to the cause I guess I could do it once more. It would have to be a experienced dev with a proven track record though. I'm not rich by any means I'm just impatient for a Unlocked bootloader.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] LeftyGR:

I hate posts like this, it is full of basic factual errors that make question if its a troll, or a misunderstanding of how these things work.

I may nitpick it when I get home if anyone disagrees with my evaluation of it, but a simple view:

a) messing with dm-verity wouldnt cause system stability issues at all, either it would boot or not.

b) reverse engineering this device is no harder than previous ones, there is no insane obfuscation or anything (just some simple obfuscation). Standard toolsets would work here.

c) The "custom" symbol is just a sign of tampering, in fact I could make a standard app to cause it. It wouldn't stop or remove root from a system.

The whole post in general is gibberish.
