This statement is not debatable. It is straight up fact.
Updating Verizon Pixel unlocked bootloader with depixel8
- Thread starter LoliSmith

That's definitely an overstatement. There are unknown bugs in every piece of firmware and if someone doesn't take the time to try to find them, they remain unknown. AFAIK, jcase found the bugs in 7.1 bootloader and now has no interest in investigating any later versions of the firmware so he isn't looking for them any more. Or at least that is what he has stated publicly.
The 2 phones at issue here are on 7.1.1.
You're wrong. I've done some reversing on dePixel8. The exploit that allows you to unlock relies on the 7.1 aboot (what you are calling the bootloader), 7.1 system (which means vendor as well), and boot image.
Here is a note. You can fully upgrade with the factory image, and still remain unlocked, but, should you ever re-lock on 7.1.1, you would permanently lose the ability to re-unlock (short of another exploit surfacing), a potential workaround would be downgrading from 7.1.1 to 7.1 should you ever want to re-lock (which is possible), then remain on 7.1 until you decide to re-unlock (though there is little to no point in this method).
Thanks for the info. So does the vendor.img contain any carrier data or is it just hardware drivers?
Boot image = boot.img = kernel, yes?
system = system.img + system_other.img + vendor.img?
So then the problem is upgrading to 7.1.1 system and kernel and relocking on 7.1.1 system and kernel?
Hello... I'm not going to contribute in your research with my knowledge. I'm not a computer or security expert.
I found some little infos for you. The author sells a PDF for a few bucks if you are interested in learning about Android security:

There is an outdated version available for free. Take a look, maybe it may help you understand the partitions structure. The one sold seems to cover Android until 7.1 version.
On XDA portal, I've seen some people propose online Android security course really cheap.
Maybe the above could be a good investment for you since you seem really determined to find another exploit. Unless you learn the basics, i doubt people who learned the hard way will give you the answer. :good:
Good luck...

Vendor = proprietary hardware drivers and other configs (must match system version though or you'll get weirdness).
The rest you said is mostly correct, except that vendor is it's own partition.
Yes. But you'd need to downgrade fully to 7.1 (bootloader, vendor, system, boot) to be able to use DePixel8 again.
This only applies to unlocked Marlin and not the locked ones from Verizon that came with 7.1.1, right?
Not gonna substantiate that with anything?
An UNLOCKED vzw marlin can downgrade to 7.1 (enough relock, then use dePixel8), and back up to 7.1.1 with no problem. Its utterly useless, but it can.
Substantiate please.

A Verizon model that came with 7.1.1 cannot be unlocked. What part of this is unclear? If you have a Google device you can do whatever you want. If you want to unlock and relock a Verizon device you need to have your head examined. How is this even a discussion at this point? If you want to unlock, relock, unlock, relock then .. well need I say more? What is going on here?
?
What did I do besides ask a question for you to try and insult me?
Oops.. not directed at you. Sorry. This discussion is just so old at this point. I'm weary.

Understandable, thank you for answering when you said the opposite. I appreciate it.
