For those who are bothered by the whispers of the QFUSE blowing with a Unlocked or Locked Bootloader :

You can :

Unlock and Re-lock the Bootloader with the stock out the box - The QFuse will say ENABLED

Wipe the system Partition - AKA no android OS installed and Lock and Re-lock - The QFuse will say ENABLED

Flash the Factory images Manually ( Boot / Bootloader / Radio / System / Userdata / Cache / Vendor ) - The QFuse will say ENABLED

The Finger Print Scanner IS NOT disabled with an unlocked boot loader or Rooting.

Current root has allowed me to run - Adblock plus and Root Explorer ( paid )

Flashed TWRP and rooted and left bootloader unlocked Qfuse is still enabled.
[Nexus 6P General] Raghav_K:
what happens when you unlock and flash a custom recovery?
[Nexus 6P General] kibmikey1:
The QFuse is actually an array of different bits that control several different things on the device. In this case, we're talking about the Qualcomm secure boot fuse, which is actually blown at the factory (hence it always being enabled) to prevent an insecure bootloader from being run. It does not track any modifications to the phone other than that, so whatever you decide to do, the bootloader will always read the same thing. I think people are confusing this with Samsung Knox, which is specifically made for tracking modifications and storing them for warranty purposes.
[Nexus 6P General] cb474:
I found this information that's a couple years old, but presumably still accurate:

So, as kibmikey1 says, it would seem the Qfuse has nothing to do with unlocking the bootloader. It's just a way to set cryptographic keys in the hardware for verifying the authenticity of the bootloader, in a manner that makes it impossible to change the keys. In other words, once the fuse is blown the keys can't phyically be changed or overwritten. Presumably Google has the key and can sign new bootloader images correctly, so that when there is an update to the bootloader it will be verified properly by the chipset.

One has to wonder, how did the rumor start about the Qfuse being a way of tracking bootloader unlocks?
[Nexus 6P General] hutzdani:
The Internet that's why, people who are afraid of trying to root who don't know anything spread the rumors.

Deemed as a good excuse not to root or scare others off.
[Nexus 6P General] chrisexv6:
Have you tried to use Android Pay while rooted? Curious if it really does cause the cards not to read (since a workaround is needed to even add cards to begin with)
[Nexus 6P General] av8rdude:
I'm curious about just unlocking the bootloader and the status of Android Pay?
[Nexus 6P General] one7dchevy:
Anyone's Nexus imprint flaky after bootloader unlock? About 80% of the time when I place my finger on the sensor, it wakes up to the lock screen (waiting for pin code I set up). Other times it wakes/unlocks to home screen. The only thing I have done is unlocked the bootloader and installed my apps via play store..

I have even started to disable apps that could interfere like Cerberus, but it does not seem to have any affect..
[Nexus 6P General] italia0101:
Nope, mines identical to before unlocking , try re adding your finger print
[Nexus 6P General] one7dchevy:
Hmm ok thanks! Guess I'll live with it until after I root/twrp and flash a new rom.
[Nexus 6P General] ctbear:
If you use an app that turns off the screen, this will happen. I made the same mistake and restored the 'Screen Off' app.

I have since uninstalled it and locks my phone with the power button exclusively. Not as convenient, but I really like the Imprint :)
[Nexus 6P General] one7dchevy:
haha you know what, I just realized that as I was sitting down to check this thread again. Ironically your post nailed it.
[Nexus 6P General] staticx57:
Same here
[Nexus 6P General] ritchea:
Don't mean to hijack as imprint is different, but I'm interested in a definitive response on this also. As of 12 hours ago, I hadn't been able to locate this info. I've read that unlock disables Pay, but I'm not sure that was from a non-rooted user. On N5 L, Android Pay works with unlocked bootloader. So, has anyone been able to use Pay on non-rooted, unlocked 6P?
[Nexus 6P General] nkornbau:
My 6P's bootloader is unlocked. I haven't changed anything else (stock recovery, unrooted., etc) and Pay works fine for me.
[Nexus 6P General] msaly:
You've used Pay, not just added cards with the unlocked bootloader?
[Nexus 6P General] ritchea:
Thanks for the post. I will ask the same question: you've actually used it?
[Nexus 6P General] nkornbau:
I have paid with it several times now, without issue.
[Nexus 6P General] ritchea:
Thanks.
[Nexus 6P General] RHChan84:
Pay doesn't work once you rooted if I'm not mistaken.
[Nexus 6P General] designgears:
I finally took the plunge and unlocked my bootloader, installed twrp and the custom kernel+/system-less root. Pay still works, imprint still works and all is well. :) (well, except only one of my cards is supported by Pay, #fail)
[Nexus 6P General] chaco81:
so it would appear based on the info that as long as we dont mess with bootloader partition, and always use a "official" bootloader we should be good regarding tripping the Qfuse?

or am i wrong?

i mean, i see no reason to ever have to mess with the bootloader anyways....
[Nexus 6P General] designgears:
Should be fine, and I see zero reason to touch the bootloader, it allows us to unlock, that is all I ever need it to let me do :)
[Nexus 6P General] chrisexv6:
fastboot oem unlock ?

And you are 100% sure you can actually pay with Android Pay?

Thats the first Ive heard that....and its great honestly!
[Nexus 6P General] designgears:
Yup, confirmed by other people already.

Also, there is no more fastboot oem unlock ;)
[Nexus 6P General] chrisexv6:
Awesome.

I did see a post talking about the new SuperSU that stated the "loophole" that allows Android Pay to work with the new rooting process might actually be closed at some point :(
[Nexus 6P General] badboy47:
Tbh am I the only who doesn't care much about Android pay? Sure its a great side feature but is it a deal breaker? Not for me. I take root anyday over Android pay.
[Nexus 6P General] chrisexv6:
After having my credit card info stolen a couple times because of system breaches at retailers, the more secure I can make this stuff the better.

Using a fingerprint reader in conjunction with Android Pay (which generates one-time-use virtual card numbers) feels a lot more secure than swiping my card at a merchant, even with the new "chip readers" which dont prevent the actual breaches anyway.

Im as big a crackflasher as the rest of em but would really like to be able to use Android Pay as well.
[Nexus 6P General] badboy47:
Oh k in that cases i feel you bro. I usually get a text message as soon my cc is charged anywhere which helps me stay up to date.
[Nexus 6P General] jasonjw12:
Can anyone confirm that the latest release of Android Pay still works with the system-less root configuration listed in this thread?
[Nexus 6P General] enigma4321:
Didn't have an issue at all with the bootloader unlocked. Imprint works perfectly
[Nexus 6P General] efrant:
Probably because some users remember the Nexus One -- on that device, once you unlocked the bootloader, you could NOT re-lock it.
[Nexus 6P General] Phazmos:
Those who can follow instructions do it right, have no problems, and have nothing to write.

Those who can't follow instructions have problems, and write about it.

Having dealt with tech, and users, for something like 25 yrs, there are a LOT of users who can't follow instructions!
[Nexus 6P General] TECK:

[Nexus 6P General] nrfitchett4:
yep, scary first time because you think you broke it, but it's just a warning and then it goes through boot sequence. Not sure why google felt like it needed that there.
[Nexus 6P General] Phazmos:
Lol - the good thing is they pay!

My "career" is now on the golf course thanks to all those good people.
[Nexus 6P General] befaka:
Got an email about that screen from a buddy who was going through the motions on his new 6p, and he was pretty freaked out... I think Samsung Knox has over permeated into a lot of people's brains
[Nexus 6P General] dbroer91884:
Okay so making sure I understand this. If I'm impatient and want to flash the newest version of Android to my phone. Following Google directions I will unlock the bootloader, flash it, then relock the bootloader. Sounds like this will not pop the qfuse and will keep the warranty in tact. Correct?
[Nexus 6P General] Koopa777:
Correct.
[Nexus 6P General] designgears:
No, the qfuse is popped if you unlock the bootloader, it however doesn't void the warranty.
[Nexus 6P General] Alaris:
So the default status of the qfuse is enabled right?
[Nexus 6P General] uicnren:
the only status for the qfuse as reported by the phone will ever be, is 'enabled' it doesnt matter what you do to the phone.

the fuse is 'popped' at the factory before anyone ever receives their phone. unlocking/locking has absolutely no bearing on the qfuse status.
[Nexus 6P General] PieOfJustice:
This ^^^^^^^^^^

I think it's safe to lock this thread now as we have our answer and every other post seems to add to the confusion.

locking boot loader

if i unlock root and custom rom on nexus 6p can i lock the bootloader when i am done? will it effect anything besides i will not be able to reflash until i unlock. figure to get rid of the error msg on the nexus 6p when it boots
[Nexus 6P General] ZheGoose:
My phone is currently stock and won't install the January 2016 security patch update, is this because my boot loader is unlocked? The update tries to install but after a second or two the android mascot is lying down with error in the red triangle. After a minute or two the phone just reboots and I still get the notification that I need to install the update. If I re-lock the boot loader and re-flash stock will the update install? Thanks for help in advance
[Nexus 6P General] SlimSnoopOS:
Nope.

Since you are bootloader unlocked, use fastboot to install the (MMB29Q) February OTA. This guide by Heisenberg has you covered:

http://xdaforums.com/showthread.php?t=3206928

Do not lock your bootloader. Should you run into any issues, you will not be able to recover from it.
[Nexus 6P General] ZheGoose:
Well the main reason I want to lock my boot loader again is that I don't want to flash new updates, I want to be able to install OTA updates just like a stock phone would receive them. I was planning on using WugFresh's nexus tool kit to relock the boot loader since its easy to use. But is my boot loader being unlocked the reason why I can't install this security patch?
[Nexus 6P General] SlimSnoopOS:
OTAs primarily fail if you have altered system partition or recovery partition. Any modification, whether root, Xposed, or installing TWRP can and will cause an OTA to fail. Sometimes they fail on their own. Being unlocked does not prevent you from accepting OTAs. Did you do anything besides unlock the bootloader?

I still suggest using fastboot to flash the stock images for February (MMB29Q) and leaving the bootloader unlocked. At least for the upcoming March OTA to make sure it works this time. Going forward, OTAs should install just fine. If you still want to lock the bootloader, only do so once you have flashed and returned to complete, out of the box state either through fastboot or toolkit. Locking the bootloader with modifications will likely be, for you, extremely difficult to fix or costly.
[Nexus 6P General] ZheGoose:
The device is currently stock and the build number is MMB29B with the December 2015 Patch Level, Yes the tool kit will be able to flash a new stock image again then re lock the boot loader. Would it be better to flash the newest stock image, or re flash the current build I have, relock the boot loader and then trying the OTA update again? Appreciate all the help
[Nexus 6P General] SlimSnoopOS:
Flash the newest factory image
[Nexus 6P General] ZheGoose:
Flashing the new update would be side loading the OTA update using adb, correct?
[Nexus 6P General] SlimSnoopOS:
Sure, that is one way to do it. I do not use toolkits so idk what the included process is. Alternatively, it should allow you to flash the update using factory images.

Hi all

Are there any simple to set up and straightforward to use tools around which can be used to easily modify framework2.jar for Android 5.0?

Thanks.
[Android Q&A, Help & Troubleshooting] gusget:
First of all, I wanna thank all who may contribute to solve this problem, or just by simple reading. Thank you so much. Now then, the problem.

I have an Itouch (brand) 701 (model) tablet running rockchip 312x, 8 gb of rom, 1 gb ram, @ 1.2 ghz, double usb (one is a micro-usb), mini hdmi device. Since I wanted to modify the partitions of the user and userdata (due to have 1 gb of internal storage and 5.6 aprox gb of external storage) I backuped all the partitions so now I have the parameter and partitions saved on my PC. After that I modified the parameter file so I can resize the userdata and user (internal and external) partitions and then install bigger apks and games and stuff. I made the maths and resized the partitions with the parameter file only, flashed all again with the new hex values, and made a data and cache format so the changes can take effect. The problem was that the external partition could not be mounted anymore, and everytime I tried to mount it from the android menu it appears "the nand storage can be safely removed". Thinking that the problem may be in the \dev\vold\31:8 I made the following via adb:

adb shell

su

cd .\dev\vold\31:8

mkdosfs -F 32 \dev\vold\31:8

That gave me as a result an encrypted partition: I rebooted the device and after it booted, it requested me a password to unlock the partition. Flashed all again, and removed that lock but the user partition (the external storage) still keeps unmounted.

Any help will be very thankful.

Hi, I am having trouble writing to SD card so that I can copy my data from my old phone, but I am unable to do this?
[Nexus 6P Q&A, Help & Troubleshooting] kibmikey1:
In answering this, I'm going to assume a few things. First, your bootloader is unlocked. Second, you are rooted. If not, achieve these things, and then give the following a try. Download a root file manager, like ES File Manager, for example, which, in it's settings, has a root explorer option. In that, there is a mount option. Check the ones you want as RW, and you should be good to go.

Hi everyone,

Sorry if that is a stupid question but I'm still fairly new to the android world.

I want to swap phones with my mum. I have Z3 compact and she have Z3.

Can we use PC Companion to backup the data from both phones and restore Z3 backup to compact version and vice versa?

If not do you recommend any free app to transfer all data to pc and then send them to the other device (hopefully including apps)?

Thank you all in advance,

I'd suggest using Helium - App Sync and Backup. I've never used that app since I have root, but I've heard it's pretty good and for a new user like you, this might be useful.

I don't want to be rude, but.... LOL.

1. He's "still fairly new to the android world". Good luck with understanding those messed up instructions how to root our Xperias for a such user.

2. What if he knows hot to do it but has Lollipop? Wouldn't he lose the data during the rooting procedure? He'd have to revert to KitKat which isn't compatible with Lollipop /data partition contents :)

I know there is a thread about what charger to buy, but I have a specs question. Mine z5 came with the International charger and I am in the US. I noted it is 5v and 1.5a. I have a 5v 1a charger on hand. Can I use that?
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Woza72:
Sure, it will just take longer to charge.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] BigHulkDiesel:
No lasting negative effects on the battery?
[Xperia Z5 Compact Q&A, Help & Troubleshooting] dd23:
Most certainly no negative effects. In theory it should actually be better for the battery to charge it with less current, but I don't know if that is true.

Different topic: I read that there are multiple versions of the Z5 (US, Europe, ...) and that they support different LTE frequencies. So maybe you want to check if your mobile connection works as intended, if you don't have the US version.

[Xperia Z5 Compact Q&A, Help & Troubleshooting] farfetch:
Better use an HIGHER amperage, than lower!! Charger will adapte it to phone specifics...A lower amperage will reduce your battery capacity in long time.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Walter_White:
I once connected my Z5C to an old 500mA charger (caught the wrong cable) and kept using it a bit (screen on, etc.) and it gave me a nag screen that said that the charger is not suitable because apparently the battery drain from usage was more than what trickled back in.

However, if left alone even a 500mA charger should eventually charge the phone, taking much longer though.

Generally, with chargers, you need to get the voltage right. If the Amperage is higher that what the OEM charger is it does not matter. The electronics in the device limit the charge to what the device can handle. The Amperage on the charger is the max it can deliver. In other words, the charger does not pump 2.5A into the phone forcefully, the phone just nibbles whatever it can take (say 1,5A).
[Xperia Z5 Compact Q&A, Help & Troubleshooting] dd23:
Any reliable source for that? The charging will be slower - yes, but I seriously doubt, that this has negative long-term effects on the capacity.
[Xperia Z5 Compact Q&A, Help & Troubleshooting] farfetch:
Just try it by yourself for few days

[Xperia Z5 Compact Q&A, Help & Troubleshooting] Steven1145:
I think you need a 2A charger to be sure with the Z5c. Most of my older chargers take hours to charge it, and the car USB port (Nissan Qashqai 2015) barely charges it at all.

The UCH20 that came with the phone, takes 2 hours 15 mins to charge the phone fully. I got a quick charger which takes around 1 hour and 10 mins at max
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Marmalux:
Wow, really?

It is basic electronics. The voltage must be the exact one. Amperage is what the device draws , therefore the charger must be capable to provide a minimum not a maximum.

I repeat, it is basic electronics!

Now a more pertinent question :

What are the voltages for quick charge ? Does anyone know?

If someone has a original charger with quick charge can you please state what voltages are written on it?

Should be 2 or 3 voltages with lowest 5V

Edit : Found myself the info on Sony UK website of a Sony charger.

5V@3000mA,

9V@2000mA,

12V@1500mA
[Xperia Z5 Compact Q&A, Help & Troubleshooting] Deleted member 7835385:
I also want a source for that... It's the first time in my life i hear it's the opposite... and i have been charging this phone with 1 amp or 500mA (with pc usb) for the past 4 years, battery is still fine. Only used a 1.5A charger a few times.

On the other hand, my sisters z5 had a swollen battery a year ago, she always used quick chargers...

What do you mean by that?

you are not going to notice battery degradation in just a few days of charging...

EDIT: i only notice now that i accidentally replied to a post from years ago, sorry for that...
