Lock your bootloader. It's the only solution.

You have to select the "wrong" option. See https://forum.xda-developers.com/on...ageos-17-0-oneplus-3-3t-t3990061/post81489665
Also, make sure you are running a rom that has a properly signed boot image.
Los 17.1 and TWRP 3.4 both work with a locked bootloader.

Going back from 5.1 to 5.0

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.

Just make sure you have OEM Unlock checked under dev options and you will be fine.

Since it gets reset then do I need to recheck OEM unlock option at every boot or its fine to leave it as it and I can reboot anyway I want?

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.

Seriously this thing is giving me a headache, I am not going to toggle anything in bootloader now and it's a pain to check this option everytime before doing a reboot, it was good before 5.1, it used to stay as it is.

Just leave it unlocked. If you plan on manually updating I don't understand why you would lock it. just in case something goes wrong if it's unlocked you have options. If it's locked you have very, very few

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.

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 ?

When a device with unlocked bootloader boots up, It shows a unlocked sign under the Lenovo logo.
Maybe that way people from the service center make out if a device has been unlocked and whether it still avails the warranty

I too has that doubt....how can you relock again. Normal fastboot don't allow that.
I think if you can relock, you get warranty bcz people there check bill, imei and bootloader lock or unlock status.
It's not like 15 day timer break warranty. Warranty is broken only when carryin support see unlocked logo and status on boot screen.
One can say Carryin support is dumb to differentiate relocked and locked.
If they say database shows its not under warranty, you have bill and bootloader locked status, you can say it's Lenovo server side error and have authority to file a complaint on Lenovo. So timer has nothing to do.

Some ROMs hide the OEM setting once the bootloader is unlocked, because this setting is now meaningless. If you were to relock your bootloader (not recommended unless you revert entirely to stock, system and recovery), you'd see the option again.
Edit: this should have been posted to your device's q&a thread instead of here.
