[Q] Question about unlocking bootloader

So i'm new to android but i continued to root my device. I did it the "legit" way. No tool kit. I installed drivers. ADB and used bootloader. I unlocked the bootloader when the dialog popped on my phone. I navigated and selected "unlock the bootloader" sideloaded clockworkmod touch. Installed supersu from sdcard. Booted up and i still have my pictures and i even found a folder on the phone from the gosms app I had. I know im properly rooted because i was able to flash paranoid rom 3 successfully. Everywhere i've been reading states unlocking the bootloader wipes everything! My question is this normal?

Its standard protocol made by Google. Yes its normal. Just remember if you have stuff on your storage to make sure you back up your storage before unlocking

All you had to do is setup fast boot and use fast boot command fastboot oem unlock to unlock your bootloader. A message always comes up letting you knlw that unlocking bootloader erases your data. You didn't necessarily had to adb not to mention you went and side loaded a custom recovery. Guess you beat the system. Lol

I unlocked my bootloader but it didn't wipe my data. But i didn't unlock it correctly and rooted.

The same thing happened to me. Apparently this happens if you flash the recovery right after unlocking the bootloader. Rather than unlocking, rebooting into android, then flashing the recovery.

ahhh gotcha! Thats my exact situation. I did not load into android either. Just flashed the recovery immediately afterwards. Is there any negative effects of this?

Yep. I was pretty confused too.
So far I havent had any issues and everything seems fine. I flashed superuser on stock rom, flashed CM10.1, and flashed PA and everything has gone smoothly. Its only been about a week though, so im not sure if anything will happen. But i highly doubt that it will cause anything negative to occur.

/!\ WARNING /!\ Do NOT relock your bootloader around the time of updating to 5.1!

Guys,
We've seen several people have flashed system.img's and OTA's and ended up in a bootloop.. Not the end of the world really, BUT for some reason, before you can unlock your bootloader using fastboot, you must enable OEM unlock in Developer options in Android settings - which you cannot do if you are bootlooping.
If you still have a custom recovery, you'll be fine but if you're 100%, locked bootloader and bootlooping, we haven't found a fix yet so please do not lock your bootloader.
If you feel you absolutely must relock your bootloader (at your own risk) please boot the phone up to check it works properly before doing this. If you intend flashing roms and kernels or custom recoveries, locking the bootloader is not a good idea
Please also see the below link provided by @efrant
https://support.google.com/nexus/answer/6172890?hl=en
This goes into more detail about how google have enhanced device security with 5.1 and some other pitfalls that you may wish to avoid. This is pretty salient information, so do give it a read.

Good advice, i would add to that NEVER LOCK YOUR BOOTLOADER. ???

And I would add that I completely disagree with this statement. Coming from an infosec standpoint, I keep my bootloader locked, and just suffer the reset when I need to tweak. If you don't, anyone - not just you - can replace your system partition or boot a random IMG which could inject functionality. This may not be the most common mechanism for attack as it requires physical access, but it basically obviates the encryption with a deepfreeze style boot IMG.
Additionally, when you think about this in context of the border crossing exemptions many countries, including the US, have to protections against unwarranted search, I would recommend that anyone with proprietary or sensitive business data who crosses international borders keeps their bootloader locked when not modifying the system. Also, until custom recoveries include security features, I recommend using stock.
Why are we making our phones so insecure just to have root? Not cool.

So just to be clear the correct procedure would be to boot the device after updating enable the setting and then go and lock your bootloader? Or just keep it unlocked overall.
Personally I keep mine unlocked but for those wanting to take full advantage of androids new device protection a locked bootloader would serve a purpose. Preventing someone from just flashing a custom rom and keeping your device.

Thank you for posting this...when 5.1 was dropping, I attempted to return to stock...all the way.to be able to take Verizon's OTA...when i locked the boot loader, i was stuck in a boot loop with the android guy and the gear box spinning FOREVER.....its is not easy to get out of the loop, but i managed to boot back up into boot loader mode, and force a stock image using toolkit.
I am now unlocked, running 5.1 on Verizon, have full LTE/VOLTE, can speak and surf at same time...i have not rooted yet...but just glad it was not me....had a heart attack two nights ago...

Hi root,
I saw that thread yesterday ...
I thought this was already covered when the N6 came out, to get the bootloader unlocked you had to do a 1st boot of the device and ENABLE OEM Unlock, then you were good to go to get into fastboot and unlock.
The reason was google put the option there for 5.0, vice all our previous versions which had no toggle for it.
I think it was people jumping the gun and not doing that first boot, but immediately jumping into fastboot and flashing, and that caused it, yes? Because the BL wasn't unlocked, they couldn't flash the OTA and boot img ...

This is nonsense.
You need *physical* access to it in order to carry out such an attack.
If your phone leaves your PHYSICAL access, then you already know not to trust what is on it, whether or not it has an unlocked bootloader.

There is no need to lock the device to take an OTA. You can keep it unlocked and do an ota

Not nonsense. Yes you need physical access to carry out the attack, but with a locked bootloader and the new precautions against unlocking and fastboot it makes locked bootloaders fairly bulletproof.
I cannot recommend unlocked bootloaders to anyone that works SCIF'd and leaves their phone in a shared box during the day, anyone that crosses international borders, or anyone whose phone might contain IP or trade secrets and could be a target of theft.
This is as much about trusting the phone afterwards as it is about protecting your data on the phone - even when encrypted.

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.

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.

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.

Bricked?

Hi,
I have the OnePlus 5 8GB.
I unlocked my bootload, rooted my phone, all good.
But then I realized android pay is not working with rooted phones, so i wanted to undo it.
for some reason i ran this because i found it in a guide to lock the bootloader again (yes, it was was stupid):
./fastboot flashing lock
After that i got the message that my device is corrupt and cant boot. So i ran ./fastboot oem unlock and that message disappeard.
I tried booting, but nothing happend for 10 minutes, still boot animation. so i went into fastboot, flashed twrp and tried doing a factory reset, but whatever i do, I get tons of these error messages:
Updating partition details...
Error opening: '/data/misc/[...]
Error opening: '/data/user_de/0/[...['
(No such file or directory)
What can I do?
I can even ADB sideload because of those errors.
edit:
also it shows nothing for bootloader version or baseband version in the fastboot screen.

doesnt look good. cant copy anything to device or from device

Might have to RMA the phone. I'm not sure I've seen anyone unbrick a phone after locking the bootloader with a custom recovery still installed. I hope someone knows of a way. Good luck bro.
Also, of you get it working, use Magisk, it allows Android pay to work while rooted

Since it's obvious someone tampered with the software, they may reject it.
You don't lose warranty if you root, but they won't cover the cost if anything happens to it due to the user's intervention.
If you manage to get the stock ROM onto the phone, you may be able to flash it from TWRP.

I backed up in TWRP the parititions "System Image" and "System" in case for going back.
Now my question.
Is it possible to go for going to stock when I recover it all?
Can I lock the bootloader after that?
How to use the "System Image" partition? Can I fully flash my phone to stock with it? With Recovery and so on, because there is no RUU available for me?
My System Version was 2.21.401.1 and my region is Europe/Germany.
Regards

If you have TWRP backup you simply recover the backup, wipe data and you are back to stock-ish. Naturally due to lack of original recovery you won't be able to receive/flash OTA. For HTC you simply do not exist.

Kind of. You can make OEM lock but it won't be the factory lock. It will be relock. And if you have a custom ROM at that point the phone may not let you boot up.

If you restore whole system then you will get the OTAs. (This is how I upgraded to Oreo in the first place).
Problem is with TWRP/custom recovery not being capable of performing the factory update (people are soft-bricking their phones).

When I flash the RUU for my CID from nougat to my phone, and perform an upgrade to oreo, would it result in a hard brick?

There is a topic explaining how to recover first to Nougat and then let you phone receive OTA for Oreo.
I don't know from where you can get RUU for your CID. Keep in mind it has to be the version you have or newer if you are not going to unlock the bootloader and use 3rd party tools to trick force update.

I have the ROM for my CID.
But I would know if it works without hard brick.
I am little bit afraid from it, because I tried this two years ago on my Motorola Moto G2. For one, two, times it worked, then came marshmallow with a new bootloader, so you bricked this phone like ****.

I cannot give you the guarantee. It is for you to decide. The topic explains it really good. I did it several times and no sweat at all. Other ways I don't know.

And I can downgrade to nougat and upgrade with OTA to oreo without hard brick? Did you tried that?

Yes, I did that. I went through the described procedure and restored the phone to pristine Nougat and then let it to update via OTA to Oreo.
If your phone is s-on then there hardly any chance you will hard brick it. Soft bricks can happen, naturally. But then, dependently on the case, you can recover from it by reflash, wipe or making the downgrade again via RUU.
One important key combination you have to keep in mind. By pressing (and holding) power with volume down you will see the buttons flashing. Keeping them pressed for ca. 15 sec (shorter, longer depends) forces the phone to reboot.
Good luck.

It worked. After my question I did the procedure and upgraded to oreo!
Thank you.
No Brick, but I had to erase the data and cache partition again after the first start, because it stucked at the HTC Logo after booting.
But the funfact is: I wanted to do a hard reset after my first try to boot it up, and the phone did a screenshot with the logo!

Thanks. You too!
And the software status is currently still on modified. Would it change when I lock the bootloader?

What software status? If you restore the original recovery there is no additional message during boot. If you lock the bootloader it will report as "relocked".

In the bootloader mode you see your software status. And it is still with stock rom and stock recovery on "modified"

And to my knowledge it will be like that. You have flashed unlocked (from HTC but always) bootloader and this has to be noted. It is not that drastical as KNOX for Samsung, doesn't influence the phone functioning.

When you say you followed the procedure, which exactly do you mean? Can you please help me by giving me a quick summary of the steps?

I would like to know the procedure as well.

Hi! I've installed a custom ROM, now I would like to go back to the stock ROM, I don't have a nandroid backup, what can I do?
