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.

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.

Due to organizational requirements the bootloader needs to be locked. So, here go the questions:
After flashing factory image (5.1.0 (LMY47E), is it safe to re-lock bootloader?
And when, after the final reboot and before setup?
And, will the command, fastboot oem lock, wipe EVERYTHING off the phone, like fastboot oem unlock does?
And does the Developer options setting, "OEM unlocking", need to be turned on prior to the lock?
Thanks
No one has proven that locking the bootloaders does not cause a "brick". We have seen people lock after 5.1 and get a bootloop. This becomes a brick because they cannot unlock to fix it. We don't know if the update causes the loop or the lock does.
By the way, this was a completely stock Nexus 6 (5.0.1), no root, no apps other than Google. Before the factory image flash, the "OEM Unlocking" setting in Developer Options was persistent during power on/off. Now, with 5.1 the setting turns itself off during power on/off.
So, should I re-lock the bootloader and satisfy organizational requirements and risk a boot loop or proceed unlocked? Kinda feel like a "deer in the headlights" !

Well its your choice. I recommend not locking it. However, if you do lock it and end up bricked, at least we know its the locking that causes the loop and not the flash but.... Is it worth it?
If your organization is supplying the device ( or the money for the device) you have no business unlocking it. At my organization people are fired for such things.
If they are not compensating you somehow then I don't see how they can make requirements on your device.
Sent from my Nexus 6
And if it is the unlocking/locking that causes the boot loop (hard brick) then any flashing operation that requires unlocking the bootloader will require that the system remain unlocked forever. A penalty that will afflict a portion (large?) of the Nexus 6 community. Was this an issue before 5.0? Makes one wonder if this is by design or accidental.

Yes we totally can. If you work for my company and decide you would rather use your own device for corporate email and data, that data is ours. You may use your own device but we will manage it. If it gets stolen, we will wipe it. You will adhere the same policies for corporate owned data as you will with a phone supplied by us. You will have lock screen, you will be unrooted. You will keep your bootloaders locked. Or you can use this sh*tty Nokia.
My hardware, but if I want to utilize it in the organization, then I must abide by their rules.
This post was not meant to be an organizational ethics discussion, just a request for guidance. If anyone can give me input on the original questions, I would greatly appreciate it. Especially the wipe side effect of the lock operation. Do not want to spend a lot of time configuring the device if it will be erased.
Thanks in advance

Just a little thinking out loud here. Wouldn't it be safe to have OEM Unlock checked under dev options, lock the bootloader, if you happen to bootloop OEM Unlock is still checked so you could still unlock? And then upon first boot OEM Unlock would get unchecked.

Safe? No.. The flag resets at boot. Boot loop partially boots and it could be enough to reset the flag "at first boot"
Pretty much everything is an unknown here. We do t even know where the "enable OEM unlock" flag is set. Is it in the BL or one of the various partitions? What effect would setting the flag and wiping the OS have? We just don't know.

1. Unsure at this point. If everything is stock (including recovery), I would suspect that it would be OK, but it has not been verified yet.
2. After you flash the bootloader, radio, boot, system and recovery images, and format data and cache, then would be the time to re-lock and then boot into Android.
3. Yes. But based on what I gather, the process of wiping on an N6 (when unlocking or locking the bootloader) is done via the stock recovery. So, if you have a custom recovery when you lock, I suspect that it will give you a boot loop.
4. I don't know.
Update - Success
I re-locked the bootloader and the device is working normally, no boot loop. I will continue testing over the next few days and then share what I learned.
Thanks for the help ...
Upgraded to 5.1, booted system OK
rechecked the OEM unlock option and rebooted to fastboot and locked bootloader.
No bootloop or other issues noticed.
Hope this helps.

Interesting. And you were 100% stock?
Perhaps the loop isn't caused by the lock itself then. Good to know, though still people need to be cautious

This happened to me literally tonight. I tried to lock the boot loader which was successful, from there the device would start to root into teamwin recovery. So from there I tired to flash a fully stock rom but the bootloader was locked. And then because you need permission from the OS to unlock the bootloader I was stuck. What I did is from the locked bootloader I ran the stock oem flash from a fresh download and check from wugs with the force flash enabled (make sure everything is right) miracles of miracles it worked and came back to me.
I learned my lesson. Never shall my bootloader be relocked unless my phone is out of my possession. I'm spending the rest of the time making sure that nobody can get to my data. I love the phone, but that data is my life.
So basically, we need to confirm that being 100% stock will safely allow the relocking of the bootloader on 5.1 per official instructions from Google. If it can be determined that having TWRP recovery installed is the cause of bricks then users can be instructed to be sure stock recovery is installed before relocking. My own thoughts are that this is a bug of sorts with the new security features of lollipop and I'm sure the talented folks here will get it figured out. I'm 100% stock on LMY47D that I sideloaded. Not sure I can afford to risk my 6 but I offer any assistance I can to help get this figured out.

Some of the "bricks" happened after fully flashing stock, i.e they had stock recovery. They had a locked bootloader, an OS that didn't boot and a recovery that couldn't flash anything. If they had TWRP installed, they could format data and flash a rom.zip no problem.

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.

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%.

https://download.cyanogenmod.org/?device=shamu
and it just has 1 ROM for Nexus 6. I have Nexus 6 for Sprint. Is there only 1 version of the ROM that works for all carriers ?
My old Galaxy S4 has many different builds for Sprint, ATT, Verizon, etc.... wasn't sure if Nexus has the same set up.
Yes, applies to all N6 variants.
thats because every sgs4 has a different setup for different carriers. we only have one nexus 6, and its the same for every carrier.

I didn't have a locked bootloader with Sprint Galaxy S4. If I were to restore the Nexus 6 back to stock to do an OTA update to update everything, then re-root and put a new custom ROM does the bootloader need to be re-locked, or can the factory .img be suffice to do an OTA ?
I'm still trying to learn how to do this as it is much different than the Samsung GS4. I saw there is a Nexus Toolkit by wug fresh. Is there any benefit to doing these processes by adb vs just using this progra which seems easier ?

you dont use adb for it, you use fastboot. and doung it right vs a toolkit.. toolkits dont teach you anything, and can mess things up.

Does the bootloader need to be locked to do OTAs or does the stock ROM with leaving the bootloader unlock suffice for an OTA ?

bootloader can be locked or unlocked, it doesnt matter. but i recommend that you keep it unlocked forever, as it can save your phone in certain situations. and having it locked can be the end of your device, in the same situations.

Ok. That's what I was planning on doing once it becomes unlocked. I was going to have it set like my previous GS4 and just toggle custom ROMs from there. When you mention having it locked, are you referring to when people have re-locked the bootloader then had an error flashing the stock custom ROM thus bricking the phone ? That's what worries me. Looks like the security is more stringent on the new Nexus vs. older versions.

i was actually refering to it because of the unlock setting that has to be ticked to unlock. some stock users got caught in a bootloop, then cant boot up to tick the setting, to fix their bootloop. since it cant get unlocked, their phones are a "brick".

Is this what happened to this person below ?:
http://forum.xda-developers.com/nexus-6/help/help-nexus-6-brick-t3227126
Since the stock rom did not have developer options "checked" then the bootloader can't be unlocked ? How can you tick the OEM unlock if it is in a bootloop ?

Ok that makes sense. What is the purpose of having the bootloader come locked in a stock phone then ? What does it actually do ? Prevents root ? I probably took it for granted mine was always unlocked before so all I had to do was worry about flashing the proper carrier ROM

Security.
Security in that if stolen your phone cannot be made to work for someone else...
Someone can (and likely will [emoji14]) correct me if I am wrong... But does little to secure your data...ESPECIALLY if you stay encrypted.

It does nothing to secure data from remote access, but it will protect data (if set with a password) from physical access, providing they do not know the password. The bootloader being unlocked, with no password on encryption would allow them to flash a custom recovery and pull the data off. This will be decrypted on the fly. So it works in conjunction with Encryption. To secure data from physical access, you need both.
IF your bootloader is unlocked and you have no password, you may aswell not be encrypted
Hi guys, so here is the story. My brother bought a Nexus 6, it came with 5.1 and he tried to update it via OTA today, it boot up, reboot and when powering on, it was stuck in a bootloop.
I tried first just clearing cache and data on the stock recovery, but had the same results when trying to boot up. I started to get worry but hey its a Nexus, he couldn't brick it just taking an OTA.
Well, I booted to fastboot which does fine, my computer recognozed it, i tried to faatboot flash a custom recovery but, happens the bootloader is locked, i thought I am just a command away to unlock it, but it fails telling me that the option was not thicked in settings.
I now, have no idea what else to do. Any ideas? Is there anything I can flash on the bootloader if it is not unlocked?

Offering "solutions" that are proved not to work, by promoting methods that are not recommended. These are the homeopathic solutions for the real diseases.
If your phone's bootloader is not unlocked, and the Enable OEM unlocking is not ticked then you can't do anything. And if you can't do anything, you can't do anything with tollkits either, because they are not magic pixies that solve problems, but only frontends for adb and fastboot.

Thanks for clarifying. So, I guess the phone is basically bricked with no known solutions, correct?
To be clear:
You seem to know your way around fastboot, so the tip to use a toolkit is a bit useless (and not recommended by a large part of xda).
And about your problem: Your brothers N6 is a brick, sorry. With a locked bootloader and no custom recovery there is no way to recover from a bootloop if the "allow OEM unlocking" isn't ticked (found in the developer options in settings).
Since Lollipop it is quite possible to brick your Nexus by just taking an OTA. First thing I always do with my phones, even before Lollipop, is to unlock the bootloader. That way you always have a way back.
I'm afraid, you have to send it for repairs. But they'll replace it, because it's their fault.
But when you get your replacement, you really should start with unlocking the bootloader. That won't affect anything else, but if Google botches another OTA, the phone will be fixable.

Thank you both, I will in that case send it back to google and make sure my brother unlocks the bootloader as soon as he gets it.
