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.

Well we gotta tune in the preliminary results for rooting the 5x. NEXT time on- But for real tho. That's such a shame!

If you don't need Android Pay, you simply riit your phone...and be done with it. I mean, how is it a shame? If you alter the device, you open up your risk to be easily exploited, or someone could compromise the Android Pay service which much be secure for the banks to be involved. If you need Android Pay which you don't, root the device. if you need it, you wont be rooting it, or buy something else. Android is about choice. If this device can't be a choice, then choose another. It's that simple.

Okay okay thank you techie. No need to be angry with me. Maybe there will be a developer out there to find an anti-trip method I dunno

And the warranty void thereby. Yeah, the beauty of Android. My a$$

What a stupid shortsighted comment. In most countries, this doesn't void normal warranty unless the unlocking/rooting is the direct cause of the malfunction. Besides jail breaking voids warranty on Apple devices too in those cases.

no hard feelings towards android, but jailbreaking and then restoring does still make the idevice under warranty, but I am no so sure about nexus anymore, what will google do if i buy a nexus 6p from their website, unlock the boot loader and something goes wrong ? will it still be considered under warranty ? But technically, I can't go back to the factory state, which clearly shows I have messed with the software inside, could google decline my warranty? This is a problem I am not facing with iPhones I guess. I really wonder why jailbreaking doesn't matter for apple pay on jailbroken idevices but it does for android pay on boot loader unlock nexus device...... probably because idevices use a dedicated chip to store the information while android still doesn't, but this is totally my speculation.

Good luck restoring when the phone is dead. And yes even unlocking the bootloader will leave the phone under warranty if for example the battery is dead. Don't know why they turned to a hw fuse to break Android pay but there isn't a word out this breaks warranty. And it shouldn't in most countries where they have the common sense rules that these operations shouldnt void warranty.

Nice update on this story (which Phonearena won't print, tipped them). Unlocking the bootloader does NOT blow the qfuse nor does it break Android Pay. Just a rumor started by someone who knows nothing

And jailbreaking your iPhone also voids the warranty. Troll better next time.

It does void. But Apple will not know if the device they have got is actually restored from jailbreak. That's a poor implementation.

First, this is implemented by Qualcomm, not Google. It is in any 810 and 808 device, including non Nexus devices. Second, the timing is coinciding with them rolling out Android Pay, and I'd imagine that financial institutions didn't want financial information available to hackers. It's right there in the article. I take it you're off your meds now, since instead of repeating the same thing in every article, you're just an aggressive asshats. Get back on the lithium.

Android Pay. Better to cater to the many over pleasing the few.

Samsung phones are out there for the masses, or they can buy iPhones. Nexus line has always been the fun one for developers to play with.

But it doesn't actually break the device. It's just a security measure

i really want android pay but... i'm stuck on cm.. hopefully with the possibility of dark theme on android N i might be able to justify stock.. :p but the material glass / material dark themes are just too beautiful to let go.

How many people buying the nexus do you think didn't plan on rooting it or unlocking the boot loader. The only people that know of nexus phones are people that enjoy tinkering. This is a smack in the face.

You're overgeneralizing. I'm looking at a 6p and I have never rooted a device. I own a Nexus 7 that's bone stock. I like Nexus devices for the Pure experience and fast updates, and many others on Android forums hear about the benefits of Nexus devices beyond rooting and romming. Regardless of who actually buys Nexus devices, anyone with more than a passing interest in smartphones or Android at the very least knows about Nexus devices.

Haha, perhaps this is the "secure enclave" alternative...now that I've switched to Android, wouldn't purchase an Android if I can't install XPosed on it.

For someone who doesn't use mobile payments via NFC, will the "QFuse" problem be bad for them?

Come on Google, what are you Apple? It's OUR phone, if we want to wipe our ass with it, let us! Just be really hardcore on the warranty replacements. If you brick your phone rooting it you know the consequences.

Notsureifsrs. I can jailbreak my iPhone 6S and it doesn't break Apple Pay. Root your Samesung phone and it trips KNOX and breaks Samsung Pay. Please respond.

20. RebelwithoutaClue unregistered

Sorry but it does sorta break Apple Pay. While JB-ing doesn't stop Apple Pay from working, it does reset it. Meaning all the cards you entered are gone as well.

No it does not break it. It get removed because you're turning the passcode off. This is a security measure. All cards will get removed from wallet when you disable the passcode. Jailbreaking or not jaibreaking.

53. RebelwithoutaClue unregistered

I did say sorta not completely. And I know it's because of the removal of the pincode. Which is mandatory for a JB to work. So don't make it sound like nothing happens to your AP.
