Unlocking the bootloader of the Nexus 6P seems to be blowing a hardware fuse, you can't reverse that


It looks like Google and Huawei just pulled a "Samsung Knox" with their latest collaboration - it seems that unlocking the bootloader of the Nexus 6P will blow a hardware fuse. This fuse is called QFuse, and sadly, you can't return it back to the default setting via any means if you desire to relock the bootloader of the handset.

This is most certainly a security feature aimed to make Android Pay more secure and reveal if the device has been tampered with. It is similar to Samsung's Knox in this regard, as the latter also employs a hardware fuse which clearly shows if the phone has been rooted or has had its firmware tampered with in any way. We don't know if the Nexus 5X also comes with QFuse on board, but we suppose that it does.

Will this affect your purchase of a Nexus 6P in any way? Make sure to let us know. In the meantime, feel free to check out our review of the device.

Google did a shout out to the Nexus One. Once you unlocked the One, you could never re-lock it. Is the 5X the same way?

If they were going this route they should have named it Google Pay instead of Android Pay. Android means feel free to do what you want. This seems antithetical to that.

Security or freedom? you got to choose.

Why not both? Security and freedom are not opposed to each other.

Exactly.....Merica. I have the freedom to sleep upside down in my bed with a shotgun under the mattress. This totally goes against AOSP.

Yes. This did just keep me from buy a nexus. I canceled my 6P order as soon as I found this out. I'm actually being serious. I use Apple pay all the time. This disabling android pay is too far. This on a NEXUS, Is WAAAAY TO FAR.

No this is not over reacting. This should have said something about this when they announced it. If there is a work around this fuse. I'll continue with my black 6p 64gb. But as of right now. This is a no go. I was really freaking excited!!

I thought modders weren't babies. Guess we have a few. Nothing is being blocked other than somebody's chance to try and like as to why about why they need a warranty replacement phone or refund. Google pay needed? Yawn. Some warning would have been nice, but I'm fine with this. Doesn't mean I'll buy one now, though. I like root.

Wtf Google? Stop it already. What happened to the very idea of a nexus phone? Unlocking and rooting the first day and enjoying the f**k out of android that very few others had access to.

And you are these reason I hate reading comment section. Do you even understand what your reading? Root to your hearts content, who said you couldn't still do that? I just better not see you commenting when you root and your Android Pay doesn't work. Cant have it both ways. "Wtf Google? Stop it already." What did Google do again?

reading the comments of the link, shows that it simply doesn't work in some instances. "I’ll be watching this to see if/when someone figures out how to make this work with an unlocked bootloader/root" "Can you root the Nexus 6 and then re-lock the bootloader? I have tried a number of ways that have been suggested to get Android Pay to work and no success. It must be the bootloader unlocked." Seems that people are trying but failing to actually pay with the device.

For some it works for some it doesnt but if you disable SuperSU and add cards it will work for anyone

calm down! then if you want to exchange the phone they won't do it because now it is officially voiding the warranty but before they accepted exchanges even if you were unlocked/rooted (at least you could go back to stock without leaving a trace) so think about what you're commenting.

also android pay works without an issue on my rooted nexus 6. so again think before you say.

First, Ron Amadeo has said that unlocking the bootloader does NOT affect Qfuse status. Second, if Phone Arena has a phone, they can just `test' it, right, and report, instead of this half assed article making accusations without testing (which you easily can). Third, many here seem to think that once Qfuse is blown there'll be problems with warranty? How did they make the assumption? Aren't all Qualcomm 810 chips equipped with a Qfuse, and it's up to the phone manufacturer to program the circumstances which will trip it? What if Google didn't program anything to trip it, and the qfuse is just there, unused and ignored? What if Google accepts phones for repair even though the fuse is blown, if only people return it at least with stock software restored? Before all these are answered people shouldn't just lose their heads.

Basically its a no win situation for Google. Google has 2 options here. 1st - they add back end protection to keep everyone happy and more secure, companies are happy and they support Android Pay. But, you piss off the long time Nexus clientele who can no longer root there device. Well they can root but may lose functionality. These people are a small minority. But they in the past they are the ones who purchased Nexus devices. 2nd - leave the devices "open" piss off the major credit card companies/businesses, they will not support Android pay because of this. Im sure someway shape or form that Google stands to make more money with option 1. NOW, either way Google goes with the decision it will gain negative feedback. The tech sites are going to bitch and moan either way they go with this. Oh Google is giving the long time Nexus community the shaft with the new devices. "im never buying a nexus again" blah blah blah or "android is unsecure, cant buy android phones because they allow root and that could compromise your credit cards" No WIN!

Yup, tha's the issue. Not enough Android cheerleaders and too many Android whiners and the media is squarely on Apple's side.

Another win for the Nexus line /s

All the more reason for the HTC one A9. Bootloader unlock without warranty void or security trip. As long as the camera isn't less than excellent and the battery isn't abysmal (and I have three strong methods to boost its battery life above stock configurations), this will be my next phone.

You seem like you gotten to terms with a lot of flaws on the One A9. Good for you. But not everyone will willingly accept them.

Well if you want to root your phone, you simply wont be using Android Pay. I dont see the problem. What is a problem is peopel having a problem with it. Android Pay needs to run on a device that hasnt been compromised. if you root a device, IT'S COMPROMISED. if you want to COMPROMISE your device, then you already assume a risk of having a feature on the phone not work. This is simply a precaution. Samsung Pay doesn't work if you, ROOT the phone. What is the alternative? Well I can purchase an unlocked model, which doesn't come with Samsung Pay. With the Nexus? Well use that as your toy and buy another for your everyday use or I guess you won't be rooting it. But having an issue with a device being secure so you can have a payment option is just dumb. What Google should do is offer for you to choose a model with an unlocked boot-loader so rooting is easier, but the device will be blocked from using Android Pay. Its that simple. Which is exactly what Samsung is doing.

But you can jailbreak the iPhone and still use Apple Pay.... This is a major step back for Android that continues to show the vulnerabilities of the OS.

Until we read an article on how a suspicious app compromised Apple Pay on a Jail broken iPhone.

But that's a security flaw in Apple, not Android.

30. Rydsmith unregistered

How is that a security flaw? The same authentications are needed as well as a token based system. The problem is that eve jailbroken you get the same level of security with the payment structure in iOS that you don't get with Android. With android, once the boot loader is unlocked you lose functions, something not seen with jailbreaking. And if the response is "well don't do it" then the android proclamation of "choice choice choice" is null and void.

No, it's simply becauseeeee with Android, you do get "choice choice choice". When you crack open the bootloader, it's your device. It's a lot different and a lot deeper than just jailbreaking an iOS thing. The fact Android/Google are placing such security features is great, and due to the fact that people could actually take advantage of the Pay system shows how deep within you get from unlocking the bootloader. People need to stop crying about this Qfuze. It's a good thing. It does nothing to you and your device. It literally allows Google to have some extra info if you send in your "mysteriously" broken device and whether you should be eligible for a new one. Also, Android Pay needs some security behind it for banks and people to trust it. Rooting and unlocking the bootloader is incredibly powerful compared to jailbreaking. Also, what's to say there isn't an app on Cydia which would take advantage of Apple Pay? Apple don't do security checks for Cydia. So yes, it is a huge security flaw.

Btw you can make Android Pay work on every rooted device with RootCloak or No Device Check from Xposed. http://androiding.how/android-pay-with-root/

A non-rooted and bootloader locked android is still far customizable and feature rich than a jail broken iOS.. I agree with post 28, Apple should not allow Apple Pay on jail broken device. They should not again create a chance of being less secure than Android..
