[Q] How do i unlock sprint samsung tab S ?

Hello,
As the title says, How do i unlock my Samsung tab S from Sprint so that i can use it on AT&T or internationally? I've searched all over google and this forum itself but i couldn't find a post that explains how. Is it possible to unlock this device by adb or other methods of unlocking such as editing the hex? Any help is very appreciated!
I'm sorry if this post is in the wrong sub forum or anything. I'm new here.
Best regards.

Possibilities
This is what I found out:
The chip in my Sprint Note 3 and Samsung Tab S 10.5 is similar and when compared the base bands were different. I unlocked my Note 3 using SSU. I tried the same on the Tab S it did say unlock but nothing happened when I installed a Local SIM ( Airtel )
The other thing I would like to point out is that SM-T807V, SM-T807R4 and SM-T807P all use the same chipsets i.e, Qualcomm Snapdragon 800, and one has the possibility to choose the GSM/Global-Mode on the SM-T807V( Verizon ) I am not aware of the U.S Cellular (i.e,SM-T807R4) though. If someone could shed some light on that.
So I would assume there are 2 ways to go ahead with this, one would either be to downgrade the baseband to that of the Note 3 then install Android 4.4.2 and then use SSU to unlock ( not to sure on this method just gave it a thought though ) and the other would be to flash the ROM on the SM-T807P with the Stock ROM of the SM-807V but then we are road blocked by the Kernal so possibly we might need to fabricate a new Kernal for this.
This is my first post on xda Hope what I said has helped. Do let me know if anyone has any development on this because I am stuck too.

Several issues with the plan.
You are unlikely to be able to flash the baseband from the Note3. There is no firmware available for the t807v and no source code.

How about the SM-T807R4 ? Can we use that ?

I'd be pretty sure the bootloader would reject it.

But doesn't the SM-T807P have an unlocked bootloader?

It does, but the carrier versions seem to be more picky with what they'll flash.
The only way is to try it. Make a twrp backup then go for it.

why the the Exynos 5420 is so bad compare to the qualcomm snapdragon when it comes to optimization?

Sorry, I am new to all that but i could give it a try. I'll let you know sometime in December the Tab has gone in for a service, the battery seems to have expanded and my top left screen has poped out and then the touch stopped working and my screen went all gibberish.

Hey i had called sprint and all they told me was that this device isn't ment for global use and it only supports CDMA and LTE, and that was a shocker because the verizon one supports global use

Has anyone come up with an unlock for this yet ? I am stuck with a locked device ??

Custom ROMs on H815 TWN

Hi Guys,
Is there any way to install TWRP/Custom ROMs, on the H815 TWN variant? I tried today to unlock the bootloader today, but it still says not supported (screenshot attached), let me know if any one has found a way to Bump the kernel like on the old G2/G3 models.
Thanks everyone =D

I have exactly the same issue unfortunately. I'd be happy with ROOT for now.
I hope someone in the community can help us out.
EDIT: root (and downgrade from MM if needed) for TWN: http://forum.xda-developers.com/g4/help/twn-root-question-downgrade-root-t3328465

Sorry but it's not possible now. There's lots of us waiting for Bootloader to be unlocked for TWN model H815... but currently impossible.
Luckily we can still have Lollipop with root.

And luckily phones like the Nexus 6P or almost any other competitor allows for bootloader unlocking unlike LG.
So if you get pissed off enough, that's an option

Any way to unlock bootloader for H815 (TWN)

Hey guys,
when trying to unlock the bootloader the official way, I get the error message
"Unfortunately, your device(Taiwan , (TAIWAN) )does not support unlocking the bootloader."
LG support has not responded yet, but the message indicates what their answer will be.
Is there any way to get the bootloader unlocked other than having LG send the unlock code?
I found several threads all over the internet with people describing the same problem, but no solution was posted. Since all those threads are from mid-2015, I was wondering if anyone found a solution by now.

If you find a solution , please let me know .

( "Unfortunately, your device(Taiwan , (TAIWAN) )does not support unlocking the bootloader." )
its clear enough to me... you cant.
and theres no other way.. yet... maybe one day it will.. unofficially.

I asked this a month ago with no luck.
There hasn't been any real progress on having an unofficial bootloader unlock since august/september of 2015.....
It's almost a year since anyone has really talked about it. I don't think it's ever gonna happen :/

I asked the LG developer support. All they replied so far was that by company policy, they do not allow models other than "European market" to be unlocked at the moment.
I answered that I am not satisfied with this "policy" and that I'd like a reason for them to block customers from their freedom of choice what to do with their devices. No answer yet - will post here when I get one.

More people need to ask their developer support program to make an official unlock for the bootloder...this is not a one man job we all need to participate in this all those having TAIWAN H815 models..

Is there any way to at least gain root access on these phones? Mine is running software version "V20c-TWN-XX", which is Android 6.0 with security patch level 2016-01-01.

LP yes. but i seen 2 different post claiming root on MM with locked bootloader.

It's easiest to just downgrade to Lollipop via LGUP. Though it still took me a while to find the right pre-rooted image to flash on my phone.

I just completed the process of using LGUP to rollback to Lollipop v10c, and then rooted it. Surprisingly I was even able to get Xposed framework installed with the bootloader locked. I guess the only thing I'm really missing is TWRP, but I can live without it.
Thanks for pointing me in the right direction!

not so sure ... but LG has removed the team the worked on past phones and eithe has a new team or will be not making any more phones. .... g5 sales arent too good...

I've the H815 V20d-TWN-XX 6.0 MM with sec. patch level 2016-06-01, and as I've read, no way to unlock bootloader for this model, so frustrating.
I was hoping at least to find a way to have this particular G4 version rooted with the bootloader locked, does anyone know how can this be done?
Been looking for a solution but haven't found anything so far, I'd just flash a previous version but some people wrote in other threads that this 20d has noticeable battery improvements...
So any help with, as for now, the best way to go to get root access in this device, is very much appreciated. I've been trying to do this for weeks
Thanks!

I am assuming with the boot loader locked, there is no way to try out any of the custom ROMs here ....what a shame as I wanted to give lineage a go

There may be an unofficial way.

[VS996] Verizon V30 Bootloader Unlock/Root Progress

Hello. Just would like to get the ball rolling on this, as no one has yet to make a thread for this device. I realize chances look slim right now of any possibility, but we might as well get to brainstorming.

hope in some Root user method ....

unnecessary thread. please see below for all updates for all models. At the moment we are speculating that only ONE model will be available for unlock in the USA. The unbranded unlocked carrier model US998.

That isn't the point of the other thread the other thread is for tmobile v30 which already has a bootloader unlock just no fastboot flash commands

The first post states its for the T-Mobile model, but all the information up until now is the same as we currently have no progress. It just so happens there are more T-Mobile users of the V30 than there are of the Verizon model. Once unlock, fastboot, etc can be addressed for one unlockable model any progress will branch off onto other US unlockable models.

Not really they face different challenges and why hold back the tmo thread for issues pertaining to unlocking a bootloader when they don't need that part?

Agreed. There's also a general bootloader unlock/root thread that even supersedes the T-Mobile thread.
LG V30 - Unlock bootloader and Root
https://forum.xda-developers.com/lg-v30/help/unlock-bootloader-root-t3665927
It was started back in September, and the T-Mobile thread was a fork of that one. Because the T-Mobile people already had bootloader unlock and didn't want to discuss bootloader unlock. So they started their own thread, and that thread op says he ONLY wants to discuss the T-Mobile variant in that thread.

Well, Verizon LG V30 variant doesn't have bootloader unlock. It's quite different from the T-mobile situation. So, this Verizon thread is another fork.
ALSO, due to information not available back in September I wouldn't be surprised if some or all the bootloader locked carrier variants (like Verizon especially) have fastboot flash commands -- if someone could unlock the bootloader.
This is a complete turnaround from what I thought back in September, when it seemed LG had removed the fastboot flash commands from all the 2017 flagship phones. If you read that post I linked above I give my reasons why the change in thinking.
I still believe the LG Developer Bootloader Unlock list is the only GUARANTEED way these LG V30 phones can be rooted -- and thus why I advised everyone to buy the phones that would be eligible for that bootloader unlock list... But I would be very curious to see an AT&T or Verizon or even U.S. Cellular LG V30 model bootloader unlocked by some exploint -- to see what's underneath.
While this could all be discussed in the LG Bootloader Unlock and Root thread, there's nothing wrong with having a dedicated Verizon variant thread if there's enough interest. Basically you will need some developer to find an exploit.
Read post #2 of the T-Mobile thread. At first it seemed like it was starting out as duplicate/rehash of the LG V30 Bootloader Unlock and Root thread -- and I pointed out it was unnecessary -- until the op said he only wanted to discuss the T-Mobile variant. OK, then.
Same here.
Sent from my official carrier unlocked LG V30+ US998

I'm considering getting a V30. If I find a US998, is unlock & root virtually guaranteed? Also, it sounds like the T-mobile models are unlockable & rootable. If I find a carrier-unlocked T-mobile phone, will it be able to use Verizon's LTE technology (or whatever is the latest) or will I be stuck with GSM or something else that doesn't match the best Verizon has to offer?
Thanks!

The open market US998 V30/V30+ has not yet been placed on the LG Developer Bootloader Unlock list. Should be, soon (it's been six weeks since release).
The T-Mobile variant does not yet have root. One guy said he has it figured out, but he bricked his phone and is waiting for replacement. In the meantime, other methods are being worked on.
You wouldn't have Verizon CDMA bands with T-Mobile phone.

Most likely not, they use the iemi to identify devices.

Okay so, since I'm sticking with the VS996 (for now) I'm really optimistic on root/bootloader unlock, just to clarify though, so the current situation is that the T-Mobile variant HAS unlocked bootloader BUT commands disabled hence no TWRP or root...
On the other hand we have the Verizon variant which has LOCKED bootloader, but could potentially have all commands intact/not striped away...
So all in all, if some amazing devs find a way to unlock the bootloader, we could potentially have a strong chance of root?, (Assuming commands are actually there)

With android 8.0 officially rolled out, I'm just wondering if anyone is currently looking for any exploits/or working towards cracking/unlocking the bootloader, thanks for any replies, staying optimistic :fingers-crossed:

Personally not a developer or really know anything about developing root, but we could start a bounty for the VS996 and/or other versions.

Sounds good, hopefully this will add some encouragement to any developers currently trying :highfive:

Omg, spent hours scouring XDA for 'VS996' & even just '996' only ever finding one thread... and a random Google search finds this thread. Anyways, my adhd makes busy forums hard to sift thru and I'll cut to the chase as I've been reading for hours... On this VS996...
I have a VS996 that can be used for fodder (testing).
I hate Verizon and want on Google Fi so I'm kicking myself for not getting a Pixel at this point. You got stuff you want me to try? Sweet. I run Linux as a competent user.... But im currently in the middle of soldering a new power jack on my laptop... while ALSO in the middle of moving....
Lemme know.

Unfortunately, although I'm sure everyone in here is very appreciative of this, I don't think there's any developers actually working on the VS996, I hope there is/or will be for you guys, but don't get your hopes up...

You can't even get to the hidden menus with the Verizon variant.

Just so everyone is aware. The VS996 by Verizon does have root with unlocked bootloader. You can Frankenstein Flash vs998 firmware to 7.0 then update to vs998 8.0 then flash an exploit unlock.bin found in the 'WTF...' thread.
I successfully flashed my VS996 to 998, updated to Oreo then flashed the exploit unlock.bin and can confirm this method works.
Verizon can suck it again. Woot.

Which model to use with Verizon for bootloader unlock

Hey all,
Been trying to weed through the information to figure out which models of the plus and ultra will work with Verizon and allow a unlocked bootloader. Any help would be appreciated.

research what bands vzw uses then see which unlockable models have those bands enabled
