So I have received a "Certified Pre-Owned" Nexus 5 from T-Mobile just a couple days ago. Within the first few hours, I rooted it. At this point I could no longer install (but still received) OTAs, and IIRC that is because the system partition has been altered. I eventually did unroot, but I still could not install OTAs. Now, there is a hardware issue with the phone: it will not vibrate properly anymore. And I have tried those solutions like pressing on the back. So will need to return this phone for a replacement or repair. I have read somewhere that T-Mobile runs a diagnostic tool to check the phone software. My phone is not rooted, and I have not unlocked it or altered the ROM in any way, but will T-Mobile know that my system partition is different? Am I still covered under warranty?
You could just flash the latest entire factory image and relock the bootloader - not sure how Tmobile would be able to tell anything different especially since the nexus 5 isn't a carrier locked device.

I don't plan to unlock my bootloader at all for a while. I unrooted with KingRoot, and now my phone is identical to stock except for a couple of files in the system partition that are traces of the root. I know this because OTA installations will result in an error. But that is the only thing that differs from a stock device. Will T-Mobile be able to access the system partition or somehow force an OTA upon it and find that it was once rooted? This is what I fear. What exactly does T-Mobile do when it receives the phone to make sure it had warranty?
Actually, what I would like to know for my peace of mind is...
Is there any way that T-Mobile can find out that I rooted?

I used the Nexus Root Toolkit to unlock, flash stock, unroot, lock, set tamper to false, etc. I can install OTAs now, and there is no way that I can think that my phone can be seen as altered. Just to confirm:
Is there any way now that T-Mobile will know that I did anything?
so now that the verizon pixel has been unlocked http://theroot.ninja/depixel8.html
if i unlock the bootloader and install custom recovery (when it's released) will i be able to install factory images from google or will it relock the bootloader? am sure verizon will be patching this soon. so if this makes me stuck on 7.1.1 I won't buy through verizon of course. my old galaxy s4 was stuck on an old bootloader image so i could only use roms up to a certain version. i read a few people stating that they tried to flash the google factory images after and it took, but the depixel tool was still necessary to unlock the bootloader after the install. anyone know this what can and can't be done here?
Might get a better response here http://forum.xda-developers.com/pixel-xl/how-to/verizon-pixel-xl-unlocking-discussions-t3484497
Probably better off not buying from Verizon at all...
Hey guys, I'm wondering if anyone has done this, or knows if it's possible to (after unlocking bootloader) flash the Google stock Pixel system image instead of the Verizon one? I'm assuming the hardware and firmware are identical, but am not sure and am not skilled enough (or at all) in code to know if its possible. I bought my phone through Verizon, only because nowhere else had stock. I use it on T-Mobile, but fear there may be some behind the scenes Verizon stuff going on that may hinder my phone on T-Mobile. I haven't experienced any issues yet, but with the Nov security update mentioning a specific fix for wifi calling in New Mexico only on the Verizon pixels, it makes me weary that there is more happening beneath the surface than I am aware of. Thanks for any and all help! Appreciate it.

Interesting side note on this...
I went ahead and unlocked my bootloader and flashed Google's stock Pixel image. All went well, no problems... Until I tried to use Android Pay. It's telling me my software can't be verified. And I out of curiosity checked, and the "allow OEM unlocking" in developer options is still greyed out, and not selectable, even though my BL is unlocked. Hoping this doesn't mean that we can't take an OTA. Weird, I guess we'll have to wait and see when next month's security update comes out...

Just having an unlocked bootloader trips SafetyNet now and you can't use Android Pay without a custom kernel.

And the OEM unlock option appears to be dependent on device ID (imeid? Ccid?), And not the software. So don't relock it, and you're fine

One thing I just realized, is in Developer Options, its greyed out like I mentioned, but also says "Bootloader is already unlocked". Which I actually remember seeing on my Nexus 5x when the bootloader was unlocked. It's got me really curious about re locking the bootloader. Mainly cause I actually use Android Pay. Had no idea bootloader unlocks are actually tripping safety net now. Major bummer. If anyone has gone through this process with a Verizon pixel and has actually relocked their bootloader with no issues I'd certainly appreciate any info you have. Otherwise, I may have to dive in blind and hope for the best.
If you want to use Android pay, flash a custom kernel but don't root. Works for me.
Don't relock if you ever want to have it rooted, custom, etc. The unlock method isn't going to survive another security update.

Hypathetically, if I didn't want root or anything custom at all, do you think that relocking the bootloader could cause an issue while using the Stock Google image on a Verizon Pixel? I wish I had more knowledge on this, but I'm pretty in the dark on this stuff as of late... Thanks for your help!
Should be fine if all stock I think, just know that you may not be able to unlock later.

Contrary to what people are saying. You CAN relock your bootloader and then unlock it again later. However, keep in mind that at some point there will likely be an update that blocks the use of dePixel8 and you will no longer be able to unlock the bootloader unless someone writes another exploit.
I would like to find a way to permanently unlock VZW Pixels but until I get one from the Google Store to compare with my Verizon one I don't think I will make much progress.
Relocking your bootloader is as simple as running the "fastboot oem lock" command from the terminal window.
Lastly. If you want to relock the bootloader, make sure your phone is 100% stock image or you risk bricking the phone
If I were to buy the Verizon pixel and flash the unlocked (non European) image. How do you think updates would work? Would I get seamless updates from Google or would I need to flash every Ota manually. Might be too early to tell

This is exactly what I did, and I am curious as well... We'll see next month I guess, but I'm guessing it will take the OTA just fine. My wife has a Pixel from the Google store, and mine is from Verizon. I've compared everything (including booloaders) since flashing the Google store Pixel image, and every informational detail is identical. Not sure if there is some other place hidden to me that might indicate a difference, but I'm thinking that Verizon's Pixel is only different in its official software image... And, that may be it. Please don't take my word for it, I'm no developer, and know very little about any of this, but in my comparisons, they are identical now since flashing Googles official (Non Verizon, Non European) image.
Sidenote, I have yet to try this, but I'm thinking that since I am on Googles image, that if I re-lock my bootloader, that I WILL be able to unlock again after locking. I think Verizon used Googles "Allow OEM Unlocking" software toggle in developer options as the only method to actually keep people from unlocking the bootloader (again speculative), and now that I'm on Googles image, that software "block" should no longer be present, so I should in theory, be free to lock/unlock the same as Pixels purchased from the Google store... Again, I've got no proof, or actual skill to back this up, but it's a theory I have, and if I end up locking my BL again, I'll post what I find...

In the Verizon unlocking threads the people that tried relocking reported that they were unable to unlock again without depixel8, which is the same as how the Verizon phone typically works. Some people seem to have gotten into situations that could have been corrected with an unlocked bootloader, but because they had a locked bootloader that couldn't be unlocked using depixel8 they had no easy solution to get their phone working again at this time.

I forget where, but I saw written or implied that the "checking for updates" screen about third of way through initial setup of first boot uses WiFi AND sim carrier data to install Verizon custom restrictions and settings that among other effects make depixel8 required.
Even on "non Verizon phones" (which you are saying use the same build images byte to byte?)... You have to either use a SIM card or wifi and google account to allow the developer options to enable OEM unlock.
My theory: In other words, if you don't allow via SIM and a network wifi or data connect, for Verizon to mark your phone, or another carrier, then the phone can not be unlocked. So carrier models may indeed be differentiated from current factory images AFTER boot and setup.
There is a post in Q&A of someone trying to unlock bootloader without loading into the device, not having luck. This is why oem unlock toggle is so important and why people are bricking from locked bootloaders that won't unlock (so no wipe and factory images cannot be flashed.)
Another thing to consider: SIM network lock will not be flashed over.

Can all versions of Pixel have their bootloader unlocked and be rooted? Or are there some versions that cannot be rooted? In the past I had misfortune with carrier branded phones from Canada that it was impossible to unlock bootloader. It want to confirm this is not the case before gettinga Pixel. Thanks in advance.
Just to be clear I'm talking about the Pixel with 5.0" screen, so not the XL.
Google version can be unlocked. There is a tool available to unlock the Verizon version but it was patched with December's update. If you plan to get it through Verizon I would hurry up and get it because it's likely not updated yet. Then you can take out the sim and skip connecting to wifi during setup and then unlock the bootloader before updating.
It is VERY unlikely that a new exploit will be found ever for the Verizon pixel. From my understanding it was a very simple exploit that was pretty much found by mistake.

All Canadian versions of the pixel/XL are carrier unlocked and can have their bootloader's unlocked as well. And can be rooted.

Why is it "Very Likely"?
There have been plenty of phones to lose bootloader unlock exploits only to never get them back. Guaranteed unlock exploits is a thing of the past... Get in while you can or deal with it when it never becomes an option again.

Read my post again lol. I said "very unlikely".
I just received a warranty replace device with NMF26U preinstalled, now i know i can't unlock the bootloader with this android version. How do i downgrade so i can unlock the device? Any ideas?
Verizon version or Google? If Verizon, you are out of luck. You can't downgrade a locked BL phone.

Can't do anything. No downgrading. You're out of luck.
When Verizon issued the patch to prevent unlocking the BL they also blocked the ability to downgrade. As far as finding a new exploit I wouldn't hold my breath. I have never seen a Verizon device that has successfully been exploited twice. Ever.
Did you order the warranty device through Verizon or Google?
My wife has a new Verizon Pixel on the way straight from Google. Despite being BL unlocked and rooted, it automatically updated. For some reason the update broke all audio on the phone. I'm really hoping google has a stockpile of verizon phones that aren't updated.
