Should I relock the bootloader after flashing M ?

NOOO!!!!
To many folks have encountered an issue that soft-bricked their device afterwards.
You will still receive OTA with an unlocked bootloader.

you can relock it (safer) but if you want to flash any new rom later you will loose all your data. cause everytime you flash you need to unlock the bootloader. its up to you

Hang on now, lets be clear about the advice that we're giving here.
Yes, a locked bootloader is safer if a thief were to get his hands on your device. However, locking the bootloader has a whole host of other problems linked to it. For example, if you end up in a boot loop with a locked bootloader because something breaks in the rom or kernel, if you have stock recovery, you can never unlock the bootloader again, without sending it for repair.
I would suggest people using experimental ROMs should keep their bootloader unlcoked to avoid this

If I did lock the boot loader, can it not be unlocked again using NRT ? I'm wondering since this (Android M) is an official release from Google, there should be a way to unlock the Boot loader if someone wants to roll back to lollipop ... Am I wrong in this assumption ?

It's a security feature whereby if you do not have "enable OEM unlocking" set in the rom, you cannot unlock the bootloader. If you don't have it set, have stock recovery then have a rom that will not boot, you cannot set that, ergo cannot unlock the bootloader. If you're going to mess with exxperiemental previews, I would suggest not re-locking the bootloader.

I just checked and the 'OEM unlocking' option is turned on under Dev Options.
So, can I unlock the bootloader and flash back to 5.1.1 ?

Can you go back to 5.0 after flashing 5.1 Roms? Was just wondering because seen a lot of bricks ..Some bricks from licked bootloaders others from flashing..I just don't want to brick because I bought mine from someone and don't have insurance .Unless it could fall under factory warranty replacement....

You can upgraded / downgrade from any ROM. Its not a HTC
The locked boot loader issue is user error. If you lock the BL and the phone doesn't boot, you'll have to get Moto to fix it. And yes that would be covered by warranty

It depends what you're expecting in future. If you want OTA, you'll need everything to be 100% stock and the right version. If you don't care about that, minimum is system.img and boot.img.
i tried to downgrade my bootloader through fastboot from 5.1's bootloader to 5.0.1 and fastboot throws an error from moto saying it cant be downgraded.
have a question. is it ok to flash the factory 5.0.1 system and boot while on the 5.1 bootloader and radio? i have read a few threads of people bricking but it's unclear if it's possible to use an aosp rom that's 5.0.1 or 5.0.2 on 5.1 bootloader and radio.

I had been running Chroma 5.02 with the 5.1 bl and radio. I reverted the radio because of issues with TMo, but the bl seemed fine. FWIW, I made all my changes via fastboot.

It really depends what you want to do. If your bootloader is remaining unlocked, it doesn't matter. If you are locking it again, to unlock it, you must set the option before booting to bootloader so if you want to minimise risk, then you will need to set it every boot. We do not know where this setting is stored yet. I really don't understand the need for this option to be honest.

The setting is due to Google's new anti theft options ( http://www.androidpolice.com/2015/0...evice-protection-feature-and-how-do-i-use-it/ ) . If you have OEM Unlock checked this protection can easily be bypassed with a flash.

I am not going to lock my bootloader. I like it Unlocked but my point of concern is that OEM unclock option get reset to uncheck at every boot. I want to know what will happen if I reboot my phone and OEM unclock option is unchecked(means bootloader is locked, this is what I think) while my bootloader is actually Unclocked.

But who really cares if a thief can "use" the phone when it is stolen? They can't use it as a phone because the IMEI will be blocked. If they unlock it, it will wipe your data too. I'd rather not have to set an option within android to allow me to unlock my bootloader and the problems here have proven this to be a detriment to people who flash.

I am confused about something if the device is already unlocked does it matter if that OEM is ticked? I reboot twice already and it reset it back to being unticked. So what I am saying is if i go from one rom to another and that isnt ticked will it cause issues even if the bootloader is already unlocked?

No if it is unchecked your bootloader is still unlocked, but you will not be able to unlock it again without booting into your device and checking it again.
Where people are getting bricks is they are downgrading their radio and bootloader, at which point their bootloader relocks, and they are stuck at bootloader as they can't access anything other than bootloader and that is locked.

No issues going from Rom to Rom with it unchecked. Issue lies in... No OS so you can't boot up and check oem unlock, stuck at a locked bootloader screen, so you can't flash a custom recover, can't restore because you can't access recovery.

I do use a usb otg stick and usually wipe the entire phone before each rom to make sure I start fresh. After I wipe everything in twrp i go to reboot back into recovery and it brings up the no os are u sure u want to do this. This wont cause issues even if unchecked correct?

No you won't have any issues doing that. If you want to be safe though you should check oem unlock before you start flashing and wiping. We all know flashing doesn't always go as expected and the last thing you want is to end up stuck. As long as oem unlocked is checked recovering from soft bricks is easy.

Like I said after a reboot it goes unchecked so if i check it and then reboot to recovery wouldnt that uncheck it again?
I'm interested in rooting my nexus 6. I know that you have to unlock the bootloader in order to root the phone and install a custom recovery. But after all of that is done is it ok for me to re-lock the bootloader for security reasons or will it have any issues?
Thanks in advance.

Yes. Very much so.
problem is.. you now have to enable oem unlocking, to unlock the bootloader. technically, you can still be rooted and lock your bootloader. but the problem is that some have gone back and relocked their bootloader(not with root i dont think so) only to find that they cant boot up, that they end up with a boot loop. and then they cant unlock their bootloaders to flash the factory.img, because you need to check that setting first, to unlock the bootloader. honestly, i think someone with root, and twrp, would be able to. if not, you can fix it by formatting a few things(if you have twrp).

If you have a custom recovery installed, then having a locked bootloader is no more secure than having an unlocked one...

So I unlocked(htcdev) and rooted(twrp) and now I wounder if I should re-lock for security? I read that the boot-loader could have an authorized os list. Since both the system and recovery are os's would a re-lock put twrp out of control?
Thanks
I'd like to know this also. Fortunately relocking seems to be easy.

Never relock with custom roms or custom recovery still installed on your phone, this will result in bootloop.
Only way to stop this bootloop will be to unlock again but unlocking the bootloader require the stock recovery to be installed.
So with custom recovery installed and bootloader relocked = bootloop = can't unlock again. You'll have to reflash the whole firmware in ruu mode to get back the stock recovery over the custom one and then you'll be able to re-unlock to stop the bootloop.
So short answer, don't relock when not 100% stock
Ich, thanks! Glad I asked first instead of taking the chance..

Well, I rooted my device and installed PAC ROM on it, then reflashed a stock image back to my nexus and relocked the bootloader, my phone is fine, no bootloops and no issues, does this pose a problem with OTA updates?

Thing is, when your bootloader is unlocked, the device is almost unbrickable. Also, you can be unlocked, 100% stock and still get OTA's if you want. If you have a locked bootloader, mess something up and end up in a bootloop, and can't boot to android, you're stuck.
Are you saying that OTA updates work even if your boot loader is open? Does it just check your system files and recovery? In theory, if I did an OTA update right now, and my bootloader was unlocked, it would install without problems?

Yes to all your questions.
Unlock it, its free insurance and wont change or harm a thing.
you can lock/unlock your bootloader anytime you want actually, you just have to make sure that you relock your bootloader sfter making sure that you can boot properly first. because if you can't boot, and your bootloader is locked, then you are just as good as bricked. because now, to unlock your bootloader, you have to enable allow oem unlock. and if you cant boot, you cant do that.

That said, since 5.1.1, doesn't "allow oem unlock" remain ticked / selected after a reboot now? If so, it's fine to relock it, even if it doesn't boot if that is ticked.

Well it shouldn't matter. When you tick that box, it writes the change to mmcblk0p18, which is OS independent. Now that booting the rom doesn't revert that partition, if it is ticked once, it shouldn't matter if there is an OS at all.

Correct. Bootloader status has no effect on OTA. Updated script checks boot.img (kernel), system.img, and recovery. All have to be unmodified. No root, no unencrypted kernel, stock 100%.

A question for clarification, as long as the bootloader is already unlocked, the "OEM Unlocking - Allow the bootloader to be unlocked" setting under Developer options doesn't affect anything?

Yeah the title says it all. Just wondering if that's possible or not since I'm not sure if I'd have to wait for a week for my phone to be unlocked, while I could get the job done in no time.
If unlocking the bootloader is required, then would force unlocking it using mtkclient work (triggers bootloop, haven't tried to relock it and see if it fixes it)? Or will it only work through official bootloader unlocking?
