i'm turning in my phone so I want to do a complete wipe. I flashed the stock rom. I flashed the stock recovery. I relocked the bootloader via ADB. But when I go to do a factory reset it says in the upper left corner when trying to do it that it was modified and won't proceed with the reset. Please help me try to reset it to stock before I return it. Thanks!
Edit: I did all this last week so I've used the phone since I went back to stock and thus want to do another factory reset. .

Would it be as simple as unlocking and relocking the bootloader? They could figure out the phone has been tampered with but not as easily.

Hmm, i wasn't aware that it will still consider that the device has been modified, even after restoring everything and relocking the bootloader. But yeah, I guess if you unlock the bootloader again, it may factory reset again? Then yeah, relock and you should be good, especially if you are just turning the phone into a Tmo store.

Hi I have a attic that has a data problem and am going to return it to warranty, I want to try out 2.3.4 but you need to unlocked the bootloader, but is there a way to relock it so I can still have it under warranty. Also I have been trying to flash the 1.26 SBF file from www.bandinnovations.com and everytime I try to unzip it says broken something or other. Is there another link to try? Thanks

Look for 1.26 in the dev section
They probably won't even check. I warranted mine yesterday because my fingerprint scanner was peeling. I was rooted with gingerblur, and couldn't even do a factory reset, so I had to go into Android Recovery and wipe data from there, but the rep didn't even ask what I was doing, or anything. DSCs (Device Support Centers) are usually franchise stores; in other words, they don't really care too much, just there for their $8/hr.

No way to relock after unlocking the bootloader. It's a hardware lock/unlock, not software.
It may be spotted at AT&T store or service center. If they turn the phone on the first thing they will see is "unlocked" in the upper left corner. Per what it says when you unlock your phone, this "MAY" void your warranty. Don't listen to advice saying they won't care at the service center. The one where I live does everything they can to get your phone back working before replacing it. Been there a couple of times.
You can remove the "unlocked" in the boot screen by flashing back to 4.1.26, 4.1.57, etc., but the phone is still unlocked, it just won't say unlocked anymore unless you reflash the unlock, after which it will be on the boot screen again.
I would say if you are returning it, don't unlock the bootloader.
So after I tried to unlock my oem, the tablet went into a boot loop. Now I manage to get it out by running in recovery mode and wiping data but once I did that does that mean I still have my oem unlocked or do I have to unlock it all over again?
It will remain unlocked.

Are you using the Nexus 10 toolkit? I'd suggest re-locking and unlocking the bootloader again, and then follow the instructions listed. Hope that helps...

After a bootloader unlock, you have to Factory Reset as a security measure. The Nexus 7 automatically did this, but the Nexus 10 does not (but still needs the reset regardless). If you don't reset, you'll experience the bootloops you've mentioned.
The bootloader will remain unlocked unless you manually re-lock it again (you can factory reset, install custom ROM after ROM, and etc. and still be unlocked).

I figured thanks guys
Okay I tried reading some stuff and have no clue, I am a total newb at this. I have NOT rooted my phone or put a custom ROM on. I stopped using the phone like 3 months ago when I upgraded, and today I decide I want to sell it but when I try to do a Master Reset the bootloader says "Tampered" and "Locked". I do see the it is S-On. I have no clue what these things means, but this is what I read when I was doing research. I did the System Updates, but again, did nothing custom personally. I need to hard reset the phone, please help!

The "Tampered" means that the bootloader was unlocked at one time and the "Locked" means that the bootloader is Locked. If you bought it off of someone, they might have done it and didn't do a good job of ensuring the "Tampered" was removed. In order to remove the "Tampered" you would have to be S-OFF. You can still do a phone reset in Settings and it will remove all of your personal data but it will remain "Tampered" and "Locked".

I bought the phone NEW, not used. I did a Factory Reset once before just fine. The phone is S-On. I called TMobile and HTC and neither could help.
So, long story short, I recently bought a Nexus 9 from ebay which arrived with factory reset protection.
I have spoken to both Google and HTC about the situation and both were of no real help except for saying a few things outright between them to give me good enough reason to believe one of two things.
That 1 - it is possible to flash factory images over a device with a locked bootloader
or 2 - it is possible to unlock the bootloader without having access to developer settings
Anyone have any experience with either of these possibilities?

Full OTA Images can be flashed onto devices with locked boot loaders.
You need to boot into recovery and select sideload update.
Yeah, I know how to do that, but that only goes for updates, doesn't it? I tried to sideload a previous build onto the tablet but it failed the procedure, so it doesn't really solve the issue and if I flash a more recent update I still get FRP :/ If I wanted to revert back to the 7.0, or even marshmallow, would that be possible? Or does that require an unlocked bootloader?

Those are full ota images, same as factory image. Meaning full package.

Ah yes, now I see your predicament. Unfortunately, there is no "there" there. You do need an unlocked bootloader to wipe the system clean with a factory image, and as you noted, the Full OTA Image will recover you from a system that won't boot, but it won't get rid of FRP.

Exactly Hence my questions as to how do the manufacturers wipe everything and flash the new image without unlocking the bootloader? Or will it always be a trade secret?...... Hmmmm

did we ever fix this? my bootloader is locked and no os installed. Was trying to return to factory and went thru all the flashing steps successfully then at the end locked the bootloader. Now tablet says "for development purposes only not for production use" and boots back to fastboot. It will not reboot at all

Never found out how they do this.... are you able to boot in to recovery? if you can do that you may be able to flash a recovery OTA through 'apply update from ADB'. Worth a shot

If up dont mind my asking how did it get that way by just locking the bootloader? I was just about to flash stock and lock on my volantis, then read this...?

definitely don't lock your bootloader. That is a horrible move and serves no purpose

I actually reflashed last factory stock image and relocked without issue. It is a horrible move, I agree...I already miss root, but it suits the purpose. Thanks for your reply.

it's only a bad move if you make a mistake and can't repair it because your bootloader is now locked. But if it goes well then you're all set.
Having searched high and low without finding an answer, I have done a factory reset (uninstalled Magisk root, I did not install TWRP so I did not trip Knox, Odined factory image back to device) which was easy enough, but I cannot find out how to RELOCK the bootloader to original lock so the tablet is pristine. The bootloader is still unlocked after the factory reset and I need to relock it.
So... Any help out there on how does one relock the bootloader on a Tab S6?
Thanks.
Did you try this?

For the S10, but the principle should be the same - Probably worth a try.
