Disable Knox on SM-t575 - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hello all
SO I managed to get into download mode on my SM-t575 but it says that its managed by an organisation and was wondering if anyone knows how to disable the Knox on it ?
Thanks loads

Hi, does anyone know how to do this ?
Thanks

a year later and still trying to get into this tablet
anyone have any ideas ?
Thanks

Hello @Rixsta_musicman! Do you mean to be able to unlock the bootloader? I don't think there's ever a way to "disable" Knox, at least not anymore (i.e. disabling the bootloader will trip Knox and there's no way around it). Your device is a carrier device, correct? Has mobile data capability? If so, then see @googlephoneFKLenAsh's post below, which probably applies to you too:
googlephoneFKLenAsh said:
Samsung devices (at least those with snapdragon cpus) on T-Mobile are not eligible for bootloader unlock anymore from 4-5 years ago.
The only option is to get the Wi-Fi only model. No cellular model in the US supports bootloader unlock, no even for the carrier-free unlocked model if it ever exists.
Or wait for an exploit for unofficial bootloader unlock which is possible but very low chance and you may need to pay 3rd party services to unlock if it happens.

Thanks, the device has a pin code to get in that I am not sure what it is and i want to be able to get in and root it, there's no way to get past the knox pin. It does have mobile capability yes, Ill check this post thanks a lot

Protected by knox cloud apparently
Im not sure if it was on T-Mobile though originally and the device is from the UK

[Q] Network Unlocking

So I've heard about bootloader unlocking which, I guess, enables me to have full control over the device (not like rooting, I understand that) and to do stuff like flashing new ROMs, etc.
But what about network unlocking? I mean, I'd like to be able to use my phone on any network I wish, do I need to unlock the bootloader for that? Do the network restrictions automatically disappear if I unlock the bootloader?
Also, is there anyway I can disable network restrictions by myself (without using something like a special SIM card or asking for remote unlocking) without having to pay for any unlocking service or ask someone to do it for me?
Thanks in advance! :3

Hi, so to answer your question, when you unlock the bootloader the sim lock remains, also afaik there are no "free" ways in which to remove the sim lock at this moment in time, the only way is to get the unlock code from your service provider or pay a remote unlocking service.
I think i may have seen on the arc forum somewhere for a small fee you can get your boot loader unlocked and sim unlocked at the same time.
One last note if your arc is sim locked there is a chance that you wont be able to unlock the bootloader via sony ericsson developer world, depending on your carrier

That means it's also possible to unlock the boot loader remotely?
Also, if there's someone who can do it for us (small fees inc.), that means there's actually a way to do it, right?

Yes there is a way to do it, i cant remember how much it costs exactly, but it's done remotely and sim unlocks and boot loader unlocks at the same time
And is it something I can do by myself?

If someone else can do this as a paid service. Why can't someone explain how its done and make it available for free?

As for that i cannot answer.. But at a guess a lot of hard work will have gone into this. It keeps drm intact, provides Sim unlock and enables fast boot on handsets which didn't have it before, if i was in that situation with my arc i would have gladly paid, and i myself think the Dev/Devs are entitled to some hard earned cash

The boot loader can be unlocked whilst keeping drm intact?
Now that is something id be interested in paying for know anyone who would be able to do this?

Verizon Pixel Bootloader

Okay so I just got a replacement on my Verizon Google pixel and after everything was setup I noticed that in the developer options it gave me the option to unlock my Bootloader. I know the Verizon models are locked and after 7.1 the exploit was patched. I have all the Verizon bloatware so is this just a bug or is it possible? I turned off all automatic updates just in case so should I go ahead and try?

If you want to try unlocking your bootloader go for it. But there's not much benefit to unlocking your bootloader unless you plan to root or flash a custom rom or custom kernel or something. Simply unlocking the bootloader but otherwise staying fully stock will not allow your phone to pass safety net so you won't be able to use Android Pay. There have been a few other posts from Verizon customers where they got phones with the option to unlock the bootloader enabled so you probably just got lucky.

If it was shipped from Carol Stream, Illinois and if you pop in your SIM and the Verizon website calls it a non-VZW phone., then you got a Google Edition. Since OEM unlocking is not grayed out on yours, it's almost for certain a Google Edition. Same happened to me, the bloatware came when the Verizon SIM was inserted.
I agree with the above jhs39 post, though, only do it if you have a reason. I wanted the Pure Nexus ROM and ViPER4Android so I did it.

I don't have the need for it unlocked now but is it possible that an update can remove the option as I do want to flash a rom in the future.

Ah I see. It was shipped from that location and I checked the IMEI on Verizon's website and it says it's not capable for some reason so I'm guessing it's a GE.

Yeah but it really is capable, just put the SIM in
If you plan on flashing custom in the future then I would unlock now so you don't have to lose all you're data later. Rather wipe while it's new and doesn't have months of data on it.
You never know when you might get screwed over by an update and or want to flash back a version.
I say unlock to give yourself a few more exit strategies should anything go wrong and if you decide to root and rom at some point later you aren't gonna wipe your device.
If you want to pass safety net for android pay you just need to flash a custom kernel.

That's true. But if you use Android Pay or any other apps that require safety net they will stop working unless you flash a custom kernel. If that doesn't matter to you then you should unlock the bootloader while you can.

is the LG G710pm impossible to root?

Is this phone impossible to root or is there just a lack of interest in figuring out a way to unlock the bootloader? I love this phone but really miss the freedom I had on previous devices to install certain apps and run different roms. I've never had a device that has been out this long without a root available.
I guess what I'm asking is if I should consider going to a different device if there isn't a way to unlock the bootloader in sight or stick it out because it'll happen in the near future.

So far, no way to root it yet, I am stuck on the Sprint G7 myself and currently fighting with Sprint to allow me to swap to another device. I know it wont work but at least I am voicing my dissatisfaction of this device with the lack of timely updates (still on November security). If I had known now when I went to Sprint back then, I would have never chosen the LG G7. The phone itself is decent, hardware is good but lack of root, lack of bootloader unlock, and lack of timely updates make the device unusable in my opinion.
I personally am hoping I or someone else can find an exploit for ROOT and eventually bootloader but so far, not much traction has been made in that department.
I have a g710pm, running Android 8.0.0
I see in developer options there is a selection that says, "Enable OEM Unlock" wouldn't that unlock the bootloader?

Nope it will not limited fast boot won't let you run the command its basically useless
You can take a look at my post, there are all the models in my country to unlock BL and ROOT, but only in the hands of a few people, they do not intend to share this, and through this to get benefits, they provide remote unlocking and ROOT services , but need to pay, which is expensive for me, I don't know English, sorry, the reply is translated by Google...
Hey everyone! As I had said earlier, the rumors are true, most G7 variants can be bootloader unlocked. I searched many Chinese websites that had already shown rooted G7 phones but showed no clear methods besides "remote unlock services". Now the method is known! The engineering bootloader from a very unique AT&T V35 V35AWM model (abl_a and abl_b) is flashed via an Octoplus box on the G7 when in QDLoader 9008 mode. This guy from Ukraine motogvasyag posted his methods on 4pda.ru and are now on XDA here: https://forum.xda-developers.com/lg-g7-thinq/how-to/to-unlock-bootloader-root-models-t3928505
Please check out the thread, and do donate if you can. He is doing these Octoplus flashes for free.
**This method won't work on T-Mobile model (G710TM and others). I'll still be on the lookout for any T-Mobile methods.**

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.

Question Unlocking Bootloader still kill cameras?

I've had my eye on this phone for a bit now, and if all is good, I'm going to get one next weekend.
Some disturbing news though, it appears that unlocking the bootloader will completely kill the cameras. And the only way to get them functional again, is to lock the bootloader again.
SO, I guess this means that recovery, root, or anything else that requires modifiying the system in any way, will kill the use of the cameras?
Is it possible to unlock, root and do whatever, then relock the bootloader and get cameras back while still having root?
The 90% people on this community first what learn ro do is to unlock bootloader. You think that they all dont need camera or..
How is that even possible?
Once when you unblock bootloader you can do what you want, flash custom rom, custom recovery, custom Kernel. Magisk. Magisk modules..
But when you lock it ,and something got wrong ,you get hard brick phone. Bootloader must ne unlock until you use root and etc..
Camera have nothing to do with unlocking and working perfectly. I dont know who say to you ...or make a joke
Btw what phone you want to unlock?
Sometimes it is better to keep quite, specially when you are not aware about current affairs.
@ OP yes, still same.

Well, dang. That kind of kills the idea of fully functional phone with root. I mostly use root for ad blocking anymore. I don't really do the custom ROM thing all that much. Custom Android development these days isn't what it used to be.
I'm looking at either the carrier unlocked version, or the Verizon version (as I have Verizon as my carrier)
I believe rooting for ad blocking means you are paying more (now a days). In my opinion, Private DNS could be a good choice for ad block on unrooted.
I use AdAway. Works perfectly. But for best use, requires root. But yeah, other than that, I don't really use root. Would be nice to have a functional TWRP, but that may or may not happen. But that camera kill is a problem. I guess if I can get DNS to work, I won't have to worry about the bootloader at all. There would be no point.
I use AdGuard on my non-rooted phone and I don't see ads. None.
I see no reason why you need to root to just block ads. There are some great ad blocking apps out there. I love AdGuard because it works not only on my phone, but my PC as well.
There is a reason you cannot get this on the PlayStore. Google kicked it off because it works so well.

Actually that is where you are wrong. Another user on this forum unlocked their bootloader on fold3 and then their cameras where disabled. There is even a warning message on unlocking bootloader screen that states clearly that cameras will be disabled after unlocking the bootloader. Even Sony smartphones had this but then Sony removed it so cameras won't be disabled after bootloader unlock.
You can read more about it here: https://forum.xda-developers.com/t/unlocking-bootloader-will-disable-the-camera.4321957/
So if bootloader locked/unlocked doesn't much matter (at least at this point), since I have Verizon, is there any reason to spring for the Unlocked version over the Verizon version? Does the Verizon version have any more apps preinstalled on it that the Unlocked version doesn't? Does either perform any differently?
Unlocked carrier is not the same as unlocked bootloader.

What he said.
Carrier Unlock is the same as SIM Unlock which lets you use other carrier SIM Cards, has NOTHING to do with the Bootloader.
The Bootloader just unlocks the ability to flash custom Recoveries and ROM's. This does NOT SIM Unlock your phone.
Guys, I'm well aware of the difference between the two. I've been at this for 14+ years. I'm just wondering if there is a performance difference, or bloatware content difference between the Carrier Unlocked version and the Verizon Locked version.

Today, the hardware in the US variant "Unlocked" and "Verizon" versions are exactly the same. The difference is only in the software set. And you have choices there. With Odin 3B you can cross-flash between the models to get the software set you want. Hell, you can even put the TMO software on the VZW "locked" device (I use quotes there because it is only locked for 90 days, at which point it becomes fully SIM unlocked automatically). You can load the U1-XAA, the U1-VZW, the U-VZW, whatever you can get your hands on. I am currently using a Verizon device with U1-XAA software, happily on One UI 4.0 beta. The Note 10 was the last device to have different hardware profiles between carriers that prevented full cross-flash support, and that was just because of the differing 5G networks as 5G was still in its infancy.
Notice how my phone setting in the photo show my phone as being a U1 (because it reads the phones software), and my phone info page within Samsung Members shows it to be a VZW device (because it uses the serial number to look up info from its database).
If you have any specific questions about it, feel free to message me. I have been doing this stuff since the WinMo days before Android existed. I don't post a lot because very few people read AND understand.
Oh, and for clarification to all the trolls out there, my device is still bootloader locked, Knox is fully intact, and my device is still covered under warranty (This was tested with my Note20 when i had to have the NFC chip replaced, and it too was a U-VZW running U1-XAA software.).

I didnt know that unlocking bootloader can kill camera. I unlocking phones , Samsung mostly. After then Xiaomi comes with lower prices and I now unlocking Xiaomi.
Can understand why vendors doing it..
But ... Some Hacker will always find some way
I have a U1 phone on Verizon. Everything works. 5g, wifi calling etc. Not sure if Verizon video calling works but who uses that? Duo is in the dialer I think. I've used opera browser for years which has ad blocking as well. YT vanced also and fblc

It's with this batch of Sammy phones. Doesn't always kill the camera.
BUT they have tried and haven't found a work around. Maybe 12 will let us, but for now we cannot unlock withou the camera "breaking".
Please see my thread - i believe with a12 this is thankfully now moot!!!!
