Googling and searching this website have yielded nothing useful so I figured I'd ask:
Has anyone yet been able to unlock the bootloader on the sm-t807a (the AT&T model of the 805)?
Thanks in advance. I'm just itching debloat this sucker and see what it can really do.
Not yet.
Okay; further query. Does the locked bootloader just mean I'll trip knox if I flash a custom ROM or otherwise acquire root or is it more insidious than that? Because I'll trade my warranty for root any day of the week. Is there absolutely nothing I can do? I can live with just root and not being able to use a custom ROM but I don't know how long I can run this thing without xposed before I lose my mind.
Locked bootloader means nothing will flash unless it stock and signed. There's chance of a brick and/ or end up with Knox tripped just for the he'll of of it.
Has anyone gained any ground on the T-807A as far as unlocking the bootloader. All I can get into is Odin Mode. Is there a fastboot mode? I have two tablets that are locked up and unbootable because of unapproved software. (TWRPn recovery on both occasions)

From day 1 i wanted to root my nexus, i haven't just encase bugs and stuff. Is root worth risking warranty right now?
You can always flash back to stock and lock the bootloader if rooting didn't appeal to you.

What he said.
Also, rooting and adding ROMs can fix any potential bugs that your phone might have.
And, the sooner you unlock your bootloader, in order to root, the better because unlocking the bootloader erases all your memory. After that, you can back up everything and its all good.
I heard apple has a way to check if you ever jail broke something, it's a possibility that android phones have that too right? Sooooo just locking the bootloader and taking to stock might not get you a new phone right? Or have people not had any problems about returning a previously rooted phone?
if you unlock the bootloader there will be an unlock icon on the splash screen.

i dont think they can see if you rooted your phone. but if you unroot, and lock the bootloader, you will be fine.
I'm sure this sounds crazy, but here's the short version... I purchased a second Galaxy Nexus on eBay and it just came in. I activated the phone and tested calls, wifi, speakers, etc. to verify it was all working. Afterwards I flashed the GA02 update + LTE modem update (provided by sextape) using Odin 3.04. When it rebooted after flashing, the "unlock" icon was there. So once it was done, I pulled battery, went into the bootloader and sure enough it's now saying my bootloader is unlocked. The first boot and all subsequent restarts while doing the manual activation, it was locked. I compared bootloader screens when I first took it out of the packaging with my original Galaxy Nexus (unlocked bootloader) and the new one said "locked".
Has anyone ever had this happen? Does the GA02 update + LTE update by Sextape automatically unlock your bootloader?
I'm mystified...
Considering that you usually need an unlocked bl to touch the radio, i'd bet that LTE modem update tool has something to do with it. Did you check that thread? I've stayed away from odin, but perhaps that had an option checked to unlock it?

I've searched it but didn't find anything related to the bootloader unlocking. I checked the contents of the LTE tar and it's just a radio.img. As far as I know the ODIN tool is just an interface to flash the images. The same would be accomplished using fastboot flash (partition) (image). Maybe it's something inside the recovery.img sextape modified.
You mentioned odin, if you haven have a unlocked bootloader, odin does it for you......................
You need to do more research before committing..................

I'm afraid I didn't understand most of what you said nor am I sure to whom you said it to. If to me, I have flashed using ODIN in the past and it did not unlock the boot loader. This was posted only out of curiosity and I'm just chalking it up to a modification in one of the images (boot loader maybe?)
I think Mach was talking to you.. My point is that i believe the bootloader must be unlocked to even touch the radio, as part of a security measure. I do not believe you could fastboot flash anything at all without first having the bl unlocked. Then again, you say you've used odin before to flash without an unlocked bl, and i know almost nothing about odin.

You've got a point there. I switch between phones often (mostly HTC in the past) so I think I'm slightly mixed up on the different methods setup for the different handsets. Thanks for pointing it that out.

Yup referring to you.
Haven use odin before, but i remember someone said if you have a locked bootloader, flashing using odin will unlock the bootloader.
Don't know why odin did not unlock your bootloader in the past when you used it, without a unlocked bootloader, you can't flash anything.
Just a question im hoping someone can help me with
I have an S4 mini, I-9197 with std firmware, 4.2.2
build is I9197XXUBML3 which has knox and locked bootloader
I would like to get root on this device to run a particular app, but according to CF website
"UNLOCK BOOTLOADERS If you have locked bootloaders, flashing one of these will probably brick your device"
So has anyone sucessfully got root on this model phone and software or is it not possible due to locked bootloader and potentially bricking it,
Im not concerned with KNOX warranty status as i dont use any apps that need it, just need root access.

Try Towelroot
https://towelroot.com/
download, install and that should do the magic.
have tried towelroot but phone just reboots therefore is unsucessful
I guess that that phone is completely locked from modification.
Deear All,
I just bought my z2 force (t-mobile) from internet. It is an unlocked version and i can use it with my own sim card. However, i found that it cannot update via OTA as the bootloader is unlocked. I have heard that after i re-flash the firmware, the bootloader will be relocked. I am wondering, will the flashing re-activate the carrier lock?
Also, is it correct that after I flash via Lenovo Moto Smart Assistant. the bootloader will be locked again?
Is there other method to allow the phone to get OTA again?
Thanks a lot for your help.

Unlocked bootloder won't stop an ota, but a custom logo.bin will. Chances are that the seller has also flashed a logo. When you boot you should see a warning about your bootloader being unlocked, if you don't and you just see a moto logo (or any stationary image really) then you have a custom logo which will fail otas. The easiest way to remedy this is to follow Uzephi's "How to Return to Stock' thread. Then you should get otas again. It is advised never to relock your bootloader. A good example of why would be that you have a custom logo, you relock, your phone fails to boot and you can't flash anything because you locked it. There is no real valid reason to relock your phone. As for losing carrier unlock, you shouldn't, those are usually permanent. Unless it was some hack which I doubt since I believe that is only for Spring variants. Just follow Uzephi's guide and you should be back to good.

Hi
Thank you so much but you cannot explain me step by step because I'm not sure the right way.
Pretty sure with Samsungs once you trip Knox there's no way back. Made that mistake with Tab S4

Not sure what exactly you did.
Do you mean you just toggled "allow OEM unlock" in Developer Settings? If so, just go back to Developer Setting and toggle it back off.
Do you mean you booted into Download mode and confirmed you wanted to unlock the bootloader? If that's the case, I'm not sure. Maybe boot into Download mode again and see if there's an option to relock it?
Either way, unlocking the bootloader should not have tripped Knox or prevented you from using Knox services.
Now. If you unlocked the bootloader and flashed TWRP or any custom firmware, then Knox is tripped and that is irreversible. If that's the case you'll never be able to use Knox services on that device again.

I think once you unlock it trips Knox as it considers itself "vulnerable" then.

I used to think that as well; however, I've been told by a few Exynos users that unlocking bootloader itself will not trip Knox. I did some research last night and the site's I found agreed. Knox is not tripped until a custom recovery or firmware is flashed.
I'm NOT saying I'm 100% right about that. I have a US Snapdragon and haven't unlocked a bootloader since the S7Edge (I bought a Exynos model of that phone from eBay). I'm just researching and trying to help the OP best I can. It sounds like he tripped Knox and that can't be reversed, but won't know until we find out exactly what he did.

Yea SD here, he might have done something more than, instead of just toggling.
