Trying to downgrade from Android N preview 2 back down to 6.0.1, but after it downloads the update won't verify. I have a locked bootloader and the option in developer options is grayed out. Any help?

Did you try doing oem unlock in bootloader? Not sure exactly but I remember reading that the option was greyed out because it was set to permanently on to avoid issues like they had with the first preview OTA

Yeah I tried that and it failed after telling me that I needed to check the allow OEM unlock in dev options.

That`s why first and foremost you always unlock your bootloader when you get a phone, just to avoid these kind of issues. I guess you have to turn it in for RMA or repair to get it running or replaced, it should be covered by warranty though as its a Google software failure.

Hey XDA,
So today I got my N Preview 2 OTA update and everything is fine and great. However I went into dev settings today to make sure I had debugging and OEM unlocking on but, if seems the Allow OEM unlock button is grayed out. Is anyone else seeing this? It may even be stuck on the Allow setting but, I really can't tell and it's a bit concerning. Any help would be appreciated thanks!

I have to ask the obvious question. Is your device already unlocked?

Nope, status code 2 'locked' according to my bootloader.
He's right, I'm unlocked already and on np2 and I don't see OEM unlock in dev options either. They must be moving it to another location or something
Edit: I do see it now but you can't toggle the switch anymore

looks like after the fiasco of the 1st preview that bricked phones during OTA & most of them have the bootloaders locked & OEM unlock in off position, this preview has put the oem unlock in default on position.
so if I am already unlocked and I flash the 2nd preview- am I OK? will the bootloader stay unlocked?
i believe so

That makes sense...the op screen shot shows the button slider to the right (on position), even though grayed out.

Yea, you're good. As long as you don't run the "fastboot oem lock" command through fastboot, your bootloader should always remain unlocked. Even if the "OEM Unlocking" toggle is switched off, an unlocked bootloader should remain unlocked.
I'm on NPC91K with a Nexus 6 and the "Allow OEM Unlock" option is grayed out and disabled for me. My phone is currently locked and Fastboot oem unlock does not work.

Thanks for checking that out. Officially concerned now
I tried out NPC91K yesterday and the "Allow OEM Unlock" option was also grayed out , but the button was in the enabled position. After a while i out back backup and bootloader is still unlocked. In Bootloader it says Device is Unlocked Status code 3.
I am in the same situation, my phone is locked and N preview 2 now oem unlock is greyed out and disabled, anybody can suggest a way to enable this, TIA.

Check out my post here on how to get around the oem unlock problem, and get back to marshmallow.
http://forum.xda-developers.com/nexus-6/help/command-device-corrupt-update-t3362317/page2
I have lot of issues with android N(not complaining). I have tried to un enroll in beta program. But i am not getting any update notification(marshmallow update). I have tried to enroll and un enroll but i am not getting any update. I am trying to root the phone. But oem unlock option is greyed out. So i cant unlock bootloader. All possibilities are blocked. Please help me with any posibility.
Thank you!!!
greyed out on N, but always is disabled. just fastboot flash twrp recovery, then flash the latest supersu(v2.71 or newer) in twrp recovery. and thats all.
Strange. A greyed out "OEM unlock" is characteristic of Android N preview 2. Are you sure? Have you checked Settings/About phone? What version does it show?

NPC91K has a greyed out OEM Unlock in Dev Options. He is not making up stuff.
My bad - I misread the "un enroll" - strange syntax. My fault... But really no need for the comment that implies that I think he's lying...
But the unenrol OTA may take time - maybe the OP just hasn't waited long enough. I know that when I tried to unenrol I lost patience because it took so long and finally restored my last M TWRP backup.
why i have to make up for this. i just tried to get help.
edit: and as for the wait, its been a day since i un enrolled in beta program.

i just wanted to make sure, i didnt unlock the bootloader previously. is it not required to unlock bootloader before installing twrp and supersu.
thanks.
Praveen, I'm sorry for the confusion - it's my fault for misunderstanding your original post.
If you are already on Android N second preview and you just want to root the device, then you can install TWRP and root with SuperSU v2.71 - no need for an unlocked bootloader.
Perhaps I am just misremembering, but on NBD90Z, if your bootloader is already unlocked, should the developer option for OEM Unlocking be available or greyed out? Mine is greyed out (Pic attached) and only becomes available if I flash a 6.x ROM.

I recently wanted to verify my carrier unlocked status on my Nexus 6. I popped in the Verizon SIM from my recently purchased Pixel, which worked fine. I'm now worried that however Verizon is able to force OEM lock onto the Pixel has now been set on my N6 and if I relock I will be unable to unlock.
@mattfrazer,
Yes the option is grayed out on 7.0 if your bootloader is already unlocked. I'm on Fi, my bootloader is unlocked, and it's grayed out on my N6.
No carrier to my knowledge can force lock a bootloader. Once you fastboot oem unlock it, it will stay that way till you pass the fastboot oem lock command.

I understand that. My worry was not that lock would be force enabled, but that the option would not "ungrey" if I were to choose to lock the bootloader on my N6 again. Either I hadn't paid close enough attention post 7.0 upgrade, or hadn't gone through the 2 step unlock process since running 6.x to notice the option greys out if your bootloader is unlocked on 7.0. I must not be the only one as the description under the option is changed in 7.1 to say "Bootloader is already unlocked" instead of "Allow the bootloader to be unlocked"
Thanks again to you both.
there are 2 possibilities . 1 : your bootloader is already unlocked(check it by going to fastboot) 2: turn on USB debugging ON
im sure your bootloader is already unlocked
cheers

Thats a good question. I have been away from VZW for a while now but did they have an N6 branded to them? if so, did they removed bootloader unlock like they do with HTC phones branded to them? if you did buy one from google or a non branded N6 carriers have zero control over it so in theory you can lock and unlock the bootloader at any time regardless of the carrier you are using for cell service. I personally never had to go back so i never noticed the greyed out option.
But thanks for pointing this out.
It is gray if you are already unlocked so you dont hit that before you fastboot lock if you are relocking. Doing the slider first can be bad. It was a changed in N.

No, there wasn't a VZW branded N6. In the US, only AT&T had a branded N6, and FWIW it was carrier locked to AT&T. Usual rigmarole to get it SIM unlocked. This version had an unlockable bootloader, just like the Google Play Store version.

So we can simply lock it again, without having to tick it or anything?

Yes there was. Vzw was the last of the major carriers to pick it up though.

Hello I have a new Moto G6. I have enabled developer options and I've enabled OEM unlocking. But it doesn't seem to stay enabled between reboots? I just bought this yesterday. I'm trying to unlock the bootloader, but I can't unless OEM unlocking stays enabled. Am I missing something? I know there's currently no root for the G6, but still I think I should be able to unlock it, or am I mistaken?

That just allows the bootloader to be unlocked. You still would need to actually unlock it following the unlocking guide thread in the guides section

Yes I know this is not root, this is just unlocking the bootloader, yes I do have a key from motorola. But I can't do anything if OEM unlocking will not persist between reboots. I'm just trying to unlock the bootloader. And yes it is unlocked for sims.

I said nothing of root. Unless I am missing something from your original post, "Allow OEM unlocking" just allows the bootloader to be unlockable. After you tick it, reboot directly into fastboot mode (not back into android, that'll untick it again).
[GUIDE] Unlock Bootloader - This states after enabling OEM Unlock in settings (from within Android) to reboot into the bootloader (This guide says power off and then power back on while holding volume down, if you have debugging on you can just "adb reboot bootloader"). Rebooting back into Android with the bootloader still locked I believe does untick the OEM Unlock option.
ok thanks, I'll try again.
I have the XT 1925-6 US unlocked version. One of the first things I do with a new phone is to enable Developer Options and toggle OEM Unlock even though I may not Unlock the Bootloader right away.
The OEM Unlock toggle has stayed persistently on through numerous reboots with the Bootloader still locked.
Hmm.. Well I could have sworn I had seen what was described before, however it has been a while. I unlocked mine all in one go so I can't say. If it's supposed to stay on then I'd really be curious why it isn't for jloh

Flash stock firmware with latest Odin in download mode. That should get you back up and running. OEM toggle switch should re-appear within 7 days (unless the date change trick works for you). The OEM unlock thread has more background, and there is a sticky thread here for the date workaround.
I have flashed all again and its working. Weird for me is about thso OEM issue - ive never had one xd even after flash srock firmware i could switch oem unlock. Curious what's depends from

Usually that error happens when you are not on stock (rooted with twrp, etc.) and hit the OEM toggle...it sees you have modified your phone in an unauthorized way and puts you in 'jail'.
I toggled it by myself i didnt know that it should be always on...
OEM issue - what is the problem. I have heard that the problem os thatbon some phones therenis no such options .... curious why

Snapdragon bootloaders are locked so OEM unlock toggle isn't really relevant there. For Exynos there is a long thread here with lots of info. Essentially it can take 7 days to appear if you don't see it at first boot or if you end up in jail.
