[Q] Can someone please explain the rooting on this phone to me?

I apologize if there is already a thread like this, but the search wasnt working.. I know what i can do with my phone once it is rooted, I am just interested in what happens tot he actual phone. I could be wrong, but once i root it isnt it always possible to tell that i rooted it even if i unroot it so therefor all warantees are voided? sorry if im being unclear, i cant think of another way to explain it haha.

The language on the "warranty void" screen says that unlocking the bootloader "may" void your warranty. On the Nexus One, HTC usually honored the warranty if the issue was with anything hardware related and could not have been the result of software tampering. Granted, that's them and this is Samsung.
Further, unless there is something hidden in the system files that counts the number of times you unlock the bootloader, you can always relock it prior to sending it in for repair with fastboot oem lock.

So there is a way to kind of undo the root without them knowing? THanks a lot btw. I figured it was something like this.

In a nutshell, unlocking the bootloader means you will be allowed to flash non-Google/custom files to the system partition and more or less enables superuser access(aka root). Once thats done, then you "root" the device, push the Superuser.apk which will enable the rooted apps. Please check out the rooted section of my stickied FAQ for more detail on how to do this if you decide to. There are two great threads I link to.
Once you lock the bootloader, you lose access to the system partition and superuser I believe which effectively unroots it.

So basically if you want to do any sort of mods, flash roms, etc. you need to unlock the bootload and root. Thanks a lot for explaining that. I think i understand it now, but just to clarify, if i unlock the bootloader and root will i be able to get the phone back to stock without samsung knowing that i rooted/unlock the bootloader?

Yes, to mod/flash roms you need to unlock the bootloader. It's possible that sometime down the road someone may develop a method of gaining root access on the phone without touching it, but it's unlikely given the fact that we can both unlock and lock the bootloader very easily.
Right now, the answer is... more or less. If you make a NAND backup in Clockwork Recovery/Rom manager of your stock ROM, you can restore back to that, fastboot flash the closest thing we have currently to the stock recovery(check development section for this), then relock the bootloader. This will give the phone all appearances of being stock. Unless Samsung has something deep in the system files tracking the number of times you've unlocked/locked(which I doubt, since I'm sure such a system would have been found by now), you should be good to go.
Most people who have returned the phone to Best Buy have noted that they don't even power on the device or check to see if the bootloader is unlocked or if there's a custom recovery on there. But your mileage may vary.

Interesting stuff. I was under the impression that once clockworkmod is flashed there is no way to remove it at this time.
Reading this thread I'm guessing and hoping this is not the case?

I had clockworkmod installed but used rom manager to flash the 2.3.1 update and i've now got the stock bootloader back. I guess the ota update does the same? It would seem that getting back to stock is pretty easy.

My apologies, I posted that before I came to the same understanding regarding the stock recovery.
Like the poster above me mentioned there is a NAND backup of stock 2.3.1 you could restore to which has the stock recovery.

Thanks for the clarification. I'll do some more reading in the dev section

Thanks a lot, this really helped me out a lot. I will proceed to rooting

So, just want to make sure I have this straight... You unlock the bootloader, load custom recovery, SU, and now phone is rooted. If you lock the bootloader, you lose root?
For me, I'm not big on custom roms since I just don't have time to keep things up to date or participate in the bug process, but I do like to maintain backups with Titanium (my primary reason for rooting). So by locking the bootloader down I will not be able to use Titanium. Furthermore, unlocking the bootloader wipes the device. So is there a reason one would not want to keep the bootloader unlocked? Have I completely misunderstood the system?

Tired of Waiting for 4.4 OTA

Hi Everyone i got a Quite new Nexus 4.
Im tired of waiting for the OTA and decided to move on to flash in the Factory Images.
As ive been reading on alot of places it says it ruins my warranty. but according to the EU Directives it does not ruin my Hardware Warranty.
So what would you do? would you open the bootloader flash in 4.4 and lock the bootloader. is there anyway the Serviceman can see that only the bootloader been opened if i lock it directly afterwards?
best regards.

Not sure what you mean about the bootloader. Yes u can unlock and lock the bootloader. After you lock it back; no there is not to tell if it was unlocked. If you want to upgrade to 4.4; follow this guide.

I mean People have had trouble when they have been at a Official Servicecenter.
Apparently the servicecenter said that the customer have had a open bootloader then locked it before going to repair, so the Servicecenter refused to repair the phone.
I dont know if its a myth or not?
so its 100 % secure not damaging any hardware just unlocking the bootloader with nexus toolkit.

I don't know a damn thing about EU Directives. But, I've never heard of google refusing to honor a warranty on a Nexus because the bootloader was unlocked. That's kind of expected on a Nexus, and that's why google makes it so easy to do. It's not like other phones that need to utilize some exploit to do it. There is very little that can go wrong. And it can almost always be fixed by flashing another factory image again.
If it was me, I would have unlocked the bootloader the day I bought it, because unlocking it will wipe your data now. There is no way around that. But if I were you, yes I would unlock it and install whatever you want to. Locking it up again is an option. But if you want to unlock again later, you will have to wipe data, again.

I also don't know anything about toolkits, I use linux and adb/fastboot (nerd).
But yes, unlock booloader, flash the new factory images, and relock it again if you want. Like I said, unlocking a Nexus is not some taboo process to google. Simply unlocking it won't void your warranty.
They only way you can void your warranty is abuse (dropping it, getting it wet, etc) , or installing BAD software that causes the hardware to malfunction. If you are installing google's factory images, you have nothing to worry about.

Stuck on Google Logo, Can't Unlock Bootloader

Hey there.
So I tried to use the Nexus Root Toolkit to sideload the OTA, but now when I try to boot my phone it just shows the white google screen and doesn't do anything. I can use ADB and fastboot and get into the bootloader but I can't flash the factory image because I never checked the "Allow OEM Unlock" tick since I didn't plan on unlocking the bootloader. Can anyone help me out here?

This is exactly why you should never mess with updates or flashing anything with a locked bootloader. If a factory reset doesn't fix it you're likely out of luck.

if your bootloader is locked still I can't see how flashing an OTA would effect this.
Have you tried to flash just the original bootloader from the android version on your device ( not the version you wish to update to )
Fastboot flash bootloader bootloader.img
DON'T USE A TOOL KIT ! UNLESS YOU KNOW WHAT YOU ARE DOING ! There where clear instructions on how to flash OTA's on this site and likely in the toolkit.
Unfortunately this is a case of NOT reading before doing things, I have yet to see anyone recover from this.
Best of luck tho, but it might be a lesson learned the hardway a.k.a RMA

I'll attempt this. Weirdly enough when I look at device info in adb it shows it as being on the newest version. But Yeah I'll attempt to flash what I was on before.
Yeah, I mean I've done this before with no issues on my Nexus 6 and there were no issues but that was unlocked when I got it. I just thought you didn't have to unlock the bootloader to sideload OTA's? I may be wrong.

I've tied to flash stock, but can't do that due to the bootloader being locked, tried to just hard reset but it just does the same thing where it gets stuck on the Google logo.

Definitely unlock the bootloader, it isn't needed to flash an update via the stock recovery, but it is needed to get out of sticky situations like this. If your bootloader was unlocked now you'd be up and running in ten minutes.

Yeah, I'll probably wait for the update over the air for a while and maybe if I feel reallly eager I'll just make sure I unlock and such. Annoying that you can't unlock via fastboot anymore without that toggle. I get that Google is trying to make Android super secure but It's not too useful for folks like us. Sure it's bricked a lot of devices.

I've done it before with other devices. I wouldn't say it's inherently bad. It's just that there was one toggle that I wasn't aware of that caused the issue. You live and you learn.

THIS IS NOT MY IDEA !
I found this in a N9 thread and it worked according to the user with the issue, apply this with the correct t factory image ( do it with the version you have on your device not the one you tried to update to ! )
This might not work but its worth a try ! Before doing this read about ADB and Fastboot !!!!!!!!!!!!!!!! Try and understand the basics and know what the commands are doing to help backtrack e.C.t
If it does work - go to settings and allow OEM Unlock and USB debug !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Then go read from reputable sources how to flash images manually via adb !!!!!!!!!!!!!!!!!!!!!!!
I'd follow vomers guides.
Had this problem with another device cool thing to remeber is that on locked devices the only thing that is different is that there is a signature before the MAGIC header so the solution is to pull the android stock images from https://developers.google.com/android/nexus/images. Once done extract the images in both the zip and the tar that is inside the zip. You will see recovery.img inside the tar. One thing about the boot process of TWRP is that it enables adb in preboot meaning while in the boot loop you should have access to adb. With access to adb all you need to do is dd the images over the corresponding partitions: i.e.
PLEASE NOTE NOT FOR THE FEINT OF HEART. I AM NOT RESPONSIBLE FOR YOU BRICKING YOUR DEVICE.
Quote:
adb push recovery.img recovery.img
adb shell dd if=recovery.img of=/dev/block/<recoverymmcblock>
I dont know if the default recovery has adb push update so id probably recommend doing this on every partition thats inside the tar, i.e. system, boot.

Nexus 6P on boot loop after an OTA update

Hi There,
My colleague complained that he had an OTA update on his Nexus 6P and the after the update it was stuck in a boot loop where the Google logo keep on displaying.
When he bought back, he had showed it a shop already which they said they couldn't fix. However, the phone was later given to me for help and I have somehow manage to connect the device on fastboot and adb. Tried all the possible options such as unlocking the bootloader, loading .img's one by one... sideloading... etc.
No matter what I do, it keeps on doing the same boot loop. And when I leave the bootloader unlocked, it gives an error at first, then again goes back to the same.
Not sure whether what I am doing wrong or whether am I choosing the wrong build or so... would anyone care to advise?

So the bootloader is unlocked? Exactly which build have you attempted to flash with fastboot? Have you tried flashing one of the full OTA zips with the stock recovery?
PS. Whatever you do don't lock the bootloader. And don't worry about the warning you get with the bootloader unlocked, that's normal.

Thank you for the reply.. I have only locked the bootloader when I'm done with flashing... etc as it was giving me error. Regardless of the bootloader state, it kept on going through the bootloop like it didn't care.
I tried to flashing the factory image which is MTC19T and also tried the OTA which is MTC19V as said in here.
Still there's not luck!

Don't worry about the warning and definitely don't lock the bootloader because if it gets stuck locked you'll really be screwed. Go to my guide here:
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
Follow the instructions in section 10 (use the latest MTC19X build). Skip the part at the beginning about performing a factory reset because you can't actually get the phone to boot to do that. Make sure you include the "fastboot format userdata" command at the end (this will erase all data on the device). Leave the bootloader unlocked.

I have actually tried doing what section 10 says but with a different stock build.. Does that effect as well? However, let me give another shot with your said build and post back.

It probably won't work, any build should work, but it's worth a try. If that fails I can only suggest flashing TWRP recovery and trying to flash a custom ROM to see if that works.

So long as you have the bootloader.img and radio.img files, you can try to format boot as well, however Heisenberg may yell at me for even typing that
I had a similar issue - bootloop, but it was getting to the boot animation for about 3 seconds, then rebooting. When I formatted all the areas before flashing them from the stock image, it allowed me to boot up as normal. Stable ever since.

Hi There,
Coming back to the issue, I have just downloaded the build that was suggested by "Heisenberg" and tried it. It was still the same, as in the Google logo keep on flashing but the android bot just appeared once with the logo. But still there not luck as the device stays with Google logo but does nothing.
However, I'm able to see the device on fastboot. Nevertheless, I cannot seem to use adb command.. it doesn't even list on devices. Does that mean the adb isn't working?
Meanwhile, all my fastboot commands are working with no issues at all.
EDIT: When I tried the TWRP recovery, I can flash the recover, but I can seem to go to the recovery window at all as the device keep on showing "The device software can't be checked for corruption". When I pass that also the same boot loop.

I too am having the bootloop issue on my stock Nexus 6P. Is there a way to unlock the device from the bootloader? I'm unable to carry out step one on Heisenberg's guide because I'm unable to actually boot up my phone past the Google logo. Am I pretty much screwed?

Unfortunately yes. Unless you enabled OEM Unlocking in the developers menu before your phone went sideways you probably have a hard bricked phone. Is it under warranty?

I went through this in November with a completely stock Nexus 6P. I was 3 days past my one year warranty! Google would not send me a new phone. It was completely bricked by the OTA update I received! I was put in touch with Huawei. I had to send the bricked phone to them. 10 days later I received a working model back. Unacceptable that an OTA update trashes a one year old $650 phone. Luckily I had my OnePlus One still, and was able to use that while I waited. I was even able to update that to 7.1.1 since it was rooted. Obviously there is some sort of issue that we are not being told of regarding the dangers of accepting OTA updates on a stock/bootlocked phone.

Bootloop issues are common on the 6P even with custom ROMs--it just happens to be much more likely you can recover with the custom ROMs installed since the bootloader is unlocked. I think it's a hardware issue with the 6P rather than an OTA issue. It's probably not an accident that Huawei didn't make the Pixels.

Doesn't seem right that I have to "void" my warranty and install a custom ROM on an unlocked, rooted phone in order to recover from a hardware defect. That's BS pure and simple. I want to use the latest software, that's why I bought a Nexus. I want to use all the conveniences like Android Pay. That's why I don't unlock or root anymore. I rooted every Android phone I ever had until now, starting with the original Motorola Droid. Now that security is so important to Google, and you can't use all the Android features with an unlocked bootloader, they need to step up to fix these problems.

This happened to my wife's phone, sent back to Bell. Will see what happens.

Unlocking the bootloader doesn't void the warranty on the Nexus 6P. If you are under warranty then just RMA the phone if an OTA bootloops your phone. It's your choice whether to keep the bootloader locked or not but if you keep the bootloader locked it's probably impossible to recover from a bootloop. Google keeps factory images for Nexus and Pixel phones on its website but you can't flash those images with a locked bootloader. Why would they provide the images if using them voided your warranty?

You are missing my point. If I unlock my bootloader so I can recover from a boot loop that may happen, I will no longer be able to use a huge feature of the phone. Android Pay will no longer function. In days passed the rumour was your warranty was void if you unlock. I assume that was started to keep people from doing it. All I know is I paid good money for a phone that is a disaster waiting to happen it seems.
If having an unlocked bootloader is so important to recover from a bricked phone, why do they lock it in the first place? And why won't Android Pay work with it unlocked? The answer is that you no longer have a secure phone if you unlock the bootloader.

What Android version you had on your phone? What's your emmc name and ram name in bootloader? What's the manufacturing date in bootloader?

I think you bought the wrong phone. Nexus devices were never available commercially through carriers and were made for developers and people who like to flash things with their phones. There are ways to use Android Pay with an unlocked bootloader if you are so inclined. You are right that an unlocked bootloader is considered less secure but if you only install apps from Google Play or another trusted source you shouldn't have problems. You can also simply enable allow Oem Unlock in the developer menu. This doesn't actually unlock your bootloader but makes it possible for you to unlock it via fastboot if you get bootlooped and need to flash a factory image to restore. This way you can unlock the bootloader in an emergency but your phone is still secure. I think this should be enabled by default when the phones are shipped. Too many people with locked bootloaders end up with hard bricked phones where the Nexus 6P is concerned. Honestly, you would probably be better off selling your Nexus and getting something else that's more stable and made for people who have no Interest in flashing anything.

How to get a fastboot console in bootloader

Hey guys, I found this quick and tidy way to get a fastboot console inside the bootloader. You can use it to do stuff like "fastboot format (partition)", etc.
GUIDE:
Go to fastboot mode on your Pixel XL
Open a CMD on the computer in fastboot directory and write in "fastboot flash bootloader pixelcustombootloader.img" (make sure the bootloader is in the directory or else it will not flash!)
Download: s000.tinyupload.com/index.php?file_id=44700284262726497364
Note: I am NOT responsible if this screws up anything.
Also I do NOT know if theres and copyright trouble with this, if there is, Mods go take this down.

I wonder if this is the bootloader that was seen in screenshots that was used to downgrade a Verizon pixel to unlock it?

If the bootloader is locked you can't flash anything or boot anything that isn't signed by Verizon/Google/whoever.
As far as I know there's never been a downgrade workaround available where pixel8 wasn't patched, but could be wrong.

There was a guy positing pictures of someone from a cell phone shop where he was recording the procedure that they did to his phone it was a signed bootloader that allowed him to downgrade for an unlock. It was labeled HTC which people thought was weird.

Eh.. 3rd party pictures that don't come with a detailed "how to" are 99% BS or marketing.
Like I said I'm not all knowing but I'm pretty in touch with the goings-ons of the pixel and have never heard of a downgrade method for a locked bootloader.
If this shop has a private method of doing so then they sure as hell wouldn't let someone take pictures of the process.

Yea like u said the guy said they were spy shots that he snuck in. Probably bs like you said. I could careless for myself my Verizon pixel is unlocked. Feel bad for those stuck locked though. Wishful thinking I suppose.

Yeah, don't flash your bootloader with anything other than stock google imgs. If your bootloader is messed up, how do you get into fastboot to fix it? Can't change slots either afaik.

Thanks for sharing, this has loads of potential - could be used on-the-go to temporarily recover from the freeze/reboot glitch (flashing stock images tends to lower the probability of the glitch for a day or two), plus we could actually have tetherless TWRP support for Oreo with this as you could use it to fastboot boot the TWRP boot img.
That being said, I'm reluctant to flash a random bootloader on my phone with no info on where it came from. Did you make this? If so is it a patched version of the most recent bootloader? If not, where'd you find it? We need more info.
