[Q] Can't boot into android, or flash anything

Hi!
Today I updated my Nexus 6 to 5.1 and something is went wrong...
When i try to boot my device into android, i Can't because its shows a dead android with a red triangle
(this is the screen where i can go into the recovery menu by pressing power on+ vol up)
i tried to flash the rom again, but the bootloader is locked because i relocked it after the 5.1 rom flash..
and i cant unlock it again because i cant boot into android to check the OEM unlock box.
i also tried wipe data, factory reset option in the recovery menu... thanks a lot for any suggestions
(sorry for my english)

Why in the world would you relock the bootloader? Against commonsense it would seem. Also, there are threads on here dealing with the update and warning against relocking the boot loader. Those threads also describe efforts to recover from the situation.

I haven't seen anyone warning against relocking the bootloader - in fact, I see many instruction sets where relocking the bootloader is the final step, before the first reboot. Most are for returning to stock. Go ahead and use your hindsight though, you sound so smart.
And yeah, there are plenty of efforts to recover from the situation, but I'm yet to see anyone do so successfully.

If you want to update to the newest OTA you dont need to lock the bootloader back up. The bootloader can remained unlocked when doing this. Its been posted all over XDA about not having to do this. The only time you may want to relock the bootloader is when selling it to someone or trading it in. Thats it.

And saying not to do something that plenty of people want to do (like, returning to stock) isn't very significant.

returning to stock and relocking the bootloader dont go together. You can return to stock and not lock the bootloader. Locking the bootloader has nothing to do with returning a device back to stock. It returns the device back to factory state if u lock it back up. Locking the device back up only should be used for selling the device, or returning the device for repairs. not for taking a ota.

Unless I want my device to be stock - actually stock - as sold - which is LOCKED. You're telling me and others there's no downside to an unlocked bootloader. Well, that's wrong, and some people want a locked bootloader.

There is no downside to a unlocked bootloader. If i remember correctly a locked bootloader is only for oem to protect for warranty issues nothing to do with security that your describing. A locked bootloader or unlocked bootloader tells the oem that this device was unlocked or locked and will tell the consumer (us) that the warranty was void. Number one rule when taking a device back to OEM for repair is return to stock and lock device like I stated above. Security issues has nothing to do with the bootloader. From my understanding its just for the OEM warranty purposes Only!
Edit: what u described above is the same thing I described. Only need to lock device back up for warranty purposes or reselling. Thats it.

I posted the warning because people are not being careful. They are locking the bootloader without even checking it works. I've edited the post to say that. But if you're the sort of person that will be flashiogn a lot, a locked bootloader is not a good thing to have now because if you break recovery and cannot boot your device, you are at present - completely screwed. If you want to be stock, that shouldn't be an issue. Just be careful is all we're saying. ...and I cannot help it if my warning comes after some people have made this mistake. If no one made the mistake, I wouldn't have needed to post a warning. Can of peanuts "May contain nuts"... You know, because you know someone somewhere who was allergic to nuts, ate the nuts.

I have nothing against your warning - I'm glad it's there. I was replying to the other guy, saying your the existence of your warning doesn't make everyone with this problem an idiot.
Locking the bootloader without even checking it works - again - I don't often see the "reboot to make sure it works!" step before the final fastboot oem lock. Maybe I've only been reading the lousy guides.

I thought that an unlocked bootloader allowed someone without 'normal' access to the files on your phone. That's why the bootloader lock/unlock wipes the device.
You're still completely missing my point with the warranty thing. Suppose my phone's unlocked and my screen breaks. Or my USB port stops working. That big unlocked logo under the Google is going to make getting a replacement really difficult.
By saying there's NO downside to unlocking the bootloader for daily use is absurd. I wanted to go back to as-shipped state for daily use, and locked bootloader is part of that. That's a reasonable goal. I don't care if there's something about the bootloader unlocked that you find valuable. I got tired of the tinkering and decided I just wanted my Nexus 6 to be back the way it was - completely.

If guides don't say that at the moment, they definitely should now. I'll look at ours here and ask the OP's to update.

Root access is for the special files. and also i had the same issues u mentioned above and i always found a way to return a device to stock.
1) broken screen- repaired myself
2) broken usb port - repaired myself
I only take in for warranties if it has to do with something that I cant fix myself. This is a risk that all users take in this hobby.

Alright, so how do I return mine to stock?
Your self-repair solutions are laughable. You're completely missing the point. I'm done arguing this.

its not laughable. unless u buy an extended warranty the warranty is up after a year so you would have to figure the work yourself. If you are in the boat where u locked it back up and took the ota and bootlooping or whatever. your stuck till there is a solution. if u want to return to stock . Just return to stock but dont lock the bootloader back up, and flash. its that simple.
Edit: we are not arguing. Its just i have my way on repairs and you have yours. its a debate i guess
Edit: this issue has been brought up and is being researched. i was talking about the returning to stock for repairs dont try and put words in my mouth saying i know a fix.

Re locking boot loader.

Hello! I just got a nexus 6 a few days ago, and I love this phone! However, I just read on here that relocking your bootloader is a bad idea? Well, I rooted my device and installed PAC ROM on it, then reflashed a stock image back to my nexus and relocked the bootloader, my phone is fine, no bootloops and no issues, does this pose a problem with OTA updates? Thanks! I really need to know because i would NOT wanna brick this thing! Thanks!

Thing is, when your bootloader is unlocked, the device is almost unbrickable. Also, you can be unlocked, 100% stock and still get OTA's if you want. If you have a locked bootloader, mess something up and end up in a bootloop, and can't boot to android, you're stuck.

Are you saying that OTA updates work even if your boot loader is open? Does it just check your system files and recovery? In theory, if I did an OTA update right now, and my bootloader was unlocked, it would install without problems?

Yes to all your questions.
Unlock it, its free insurance and wont change or harm a thing.

you can lock/unlock your bootloader anytime you want actually, you just have to make sure that you relock your bootloader sfter making sure that you can boot properly first. because if you can't boot, and your bootloader is locked, then you are just as good as bricked. because now, to unlock your bootloader, you have to enable allow oem unlock. and if you cant boot, you cant do that.

That said, since 5.1.1, doesn't "allow oem unlock" remain ticked / selected after a reboot now? If so, it's fine to relock it, even if it doesn't boot if that is ticked.

Yes, but in the case of an "accidentally" wiped OS, well, you know.

Well it shouldn't matter. When you tick that box, it writes the change to mmcblk0p18, which is OS independent. Now that booting the rom doesn't revert that partition, if it is ticked once, it shouldn't matter if there is an OS at all.

Correct. Bootloader status has no effect on OTA. Updated script checks boot.img (kernel), system.img, and recovery. All have to be unmodified. No root, no unencrypted kernel, stock 100%.

Real quick easy noob question, no point in making a thread just for this so I'm asking here, is the Nexus 6 CPU an arm or arm64?

N6 is ARM. Arm 64 is for 64 bit devices such as the N9.

Clarification question
A question for clarification, as long as the bootloader is already unlocked, the "OEM Unlocking - Allow the bootloader to be unlocked" setting under Developer options doesn't affect anything?

How to relock the bootloader?

Hi,
I've searched and found how to do it but it was for Android 5.1 but I'm on 7.0 and I my recovery is TWRP 3.0.2-0 and apparently there are more steps to do if you are on TWRP, I'm wondering what are they.
Thanks

First, questions need to go in the Nexus 6 Q&A, Help & Troubleshooting Thread, not the General thread. Second, the steps to lock the bootloader have not changed. It's done from the bootloader with fastboot and the command "fastboot oem lock". It shouldn't matter what recovery you have.

Re-locking needs stock recovery(maybe full stock; boot, recovery, system) if you try to re-lock your boot loader without stock recovery you might hardbrick your phone. So just backup your apps and files, flash a stock image from google and re-lock your boot loader with "fastboot oem lock". Which probably needs wiping your phone.

Before you do anything search these forums for the many people who locked their bootloader and then when they had problems ended up with a bricked and useless device. Unless you have a very special reason for locking, leave it unlocked

this right here...there is really no reason to ever re lock your bootloader

I flashed the factory image and and it went fine. But the bootloader is still unlocked. My main concern for locking the bootloader is to prevent any malicious app to root the phone and hide themselves by like installing as system app or something. And I'm not planning to flash any custom ROM. So:
1- Since I'm on stock ROM, is there still a possibility of hard bricking my phone if I relock?
2- If I leave it unlocked, will malwares be able to tamper with the phone by the means I mentioned or similar approaches?
Thanks

2. No, they don't. Bootloader is on a completly different layer.

I feel your concerns. I think the safest bet is to watch where you download apps and content from. And make sure "unknown sources" is turned off. That should minimize your potential for problems. I think the main thing is watching where you get apps from.

[Q] No OEM Unlock, Rooting, and stock ROM

I know that there are a lot of the missing OEM Unlock posts, but this isn't about how to force it to appear.
What I would like to know is that if I want to stay on the stock ROM, but I don't have the OEM unlocked option, would I be able to factory reset to clear out encryption and then root with Magisk?
The guide says that I need to have OEM unlocked to be able to root, so I'm curious what would happen if I tried to root with the OEM still being locked? Would I soft brick it?
This is quite different from the other phones I've used and it's extremely frustrating that Samsung decided to pull this kind of bs on everyone and so far, there's no solution to it.
Thanks

If the OEM switch is not visible and switched on, then you cannot flash any non-official binaries, which means you can't flash TWRP or Magisk, which at this point means you can't get root. That's why everything boils down to the OEM switch being enabled. Please contact Samsung expressing your dissatisfaction about this OEM issue. All of us should, until they react to remedy this.

If we can get to fastboot, why can't we boot TWRP, install Supersu/magisk and dm-verity thus gaining root.
This wouldn't replace the stock recovery.
I believe this was how the Axon 7 was rooted prior to bootloader unlock being presented/found.
I do this on one of my phones (not Samsung) as I only want root access and still be able to get OTA updates.
Would booting TWRP instead of flashing it trip Knox and would root be gained or would you find the boot partition or other system files be altered and you get the error that seems to popping up on these devices?
Just throwing this out there as food for thought.

Having an unlocked bootloader is what would allow us to use fastboot to boot or flash an image. Just because we can access fastboot, doesn't mean we can get it to write to partitions, even temporarily. I haven't messed with a Samsung phone for years, so I could be wrong. This has been my experience with google bootloader in general.

I was reading about this as well and what I got from that was in regards to custom roms, the oem unlock option is default to unlock and hidden. but for the stock rom, it's locked by default unless visibly given the option. otherwise when you go into download mode, it'll show FRP Lock: On.

Ah, but if I want to just root and nothing else, would I still need to have the bootloader unlocked? I'm used to rooting stuff but the technicalities and mechanics of the process escapes mr.
my hope is to atleast root the stock rom and factory reset including wiping the internal sd to start fresh. but if I factory reset on a stock rom, the internal storage would still be encrypted right?

This is why I want to know if we can boot TWRP. It boots TWRP but leaves the stock recovery.
However, I'm not sure if the boot image is altered when flashing root. I know Magisk seems to alter the boot image but not sure if SuperSU does.
Would this trigger KNOX?
If it does trip KNOX, it's not worth booting into TWRP, might as well just bite the bullet and install but only if bootloader is unlocked 1st... Too expensive to just brick it for an experiment...

personally I don't care about knox. I just want to be able to root and restore my apps so I can transfer my stuff from my s7 to the note 8 and freeze all the bloatware like touchwiz and stuff.
from what I gleaned from reading the threads is magisk makes a copy of the boot image as a backup.
but again I just want root and I can wait for a longer term solution in how to fix this moronic 7 day jail bs.
but I think knox will get tripped the moment you root

I didn't have OEM option as well (FRP lock was ON), I just followed me2151 guide but I was getting the partition error, so in first part I also added BL and after that everything went smoothly.
KNOX wasn't tripped, it's rooted as of this moment and tomorrow I will be installing custom rom.
PS: And yes it was an experiment but I was willing to take the risk because after reading half a day about no OEM option in developer options everyone was saying if it's not there you don't need it, I wasn't 100% sure but I was 98% sure I'm not going to brick it. btw I'm using Telus N950W note8 (locked)

I think you might want to be careful on that. I'm not sure who "everyone" is but the others like Dr.Ketan did not even recommend rooting without unlocking the option first and it seems to me that the general gist of the other thread (the 150+ page thread) was that you need it explicitly unlocked.
The ones who talked about not seeing the option means you probably don't need it are talking about custom roms (like renovate) that purposefully hid the option since it's already defaulted to unlocked on that rom.
I haven't used any custom roms yet, but that seems to be what I'm reading.

I was able to root it but the boot loader is still locked. It's faster without the bloatware and what not. KNOX is disabled. There is still no twrp and custom rom for Snapdragon to the best of my knowledge. It did change the model of the phone from N950W to N950U1.

finally got the OEM Unlock option and rooted + stock recovery... i had to restart my phone to bring my android ID back to the one I always used.. and got locked out...
so 7 more days for me. And all I wanted to do was to have Titanium backup up and running so i can transfer my phone over....
i am hating what samsung has done

Question Help, i did something stupid.

Hello
Hoping somebody can help getting my phone up and running again.
I wanted to unroot my phone, because i was having issues with danish "MitId". And was a bit sloppy with it.
First i tried using SuperSU to remove root. Because i didnt feel like setting everything up again. Didnt work.
Then I locked the OEM Lock in developer settings. Not thinking this would be a fatal error.
Got home from work, and said to myself. Jusk lock the bootloader and the phone will reset itself.
But this is not the case, when you have been stupid enough to lock the OEM lock.
Now I am stuck on "No valid operating system could be found. The device will not boot"
I can get in to fastboot by pushning power+vol down. But cannot flash anything since the phone thinks the OEM Lock is locked on it.
Does anyone know of a solution for me. Or is it going to the shop tommorow and say that my phone is going this. And hope they will sort it for me?

Can't you fix stuff by using https://flash.android.com/ ?

No, unfortuantly not. It fails:
Device Unlock Disabled​For security reasons, you need to enable "OEM unlocking" in order to flash your device. See the device preparation instructions for more information.

Try sideloading the full OTA. You don't need an unlocked bootloader for that.

Unfortuatly not, if I try to enter recovery mode. The phone just goes back to the screen saying "No valid operating system could be found. The device will not boot"
ADB is not available to me

If you can't sideload the OTA, I'm afraid there is not much else you can do with a locked bootloader except try to RMA it.

Can you get into recovery at all. Even if it's the stock you can attempt a sideload of the stock OTA.zip from Google. You may also try if your on boot slot A
fastboot --set-active=b
On b use
fastboot --set-active=a
Try to see if the other boot slot has an a bootable OS.
*****I apologize I just saw it's actually still locked****"
Contact U-break I-fix if I typed that correctly. The third party warranty repair center for Google's warranty. I believe they can attempt to switch the boot slot with a locked bootloader with the equipment they use to reflash these devices. If anything it's under warranty get the RMA and if the bootloader is locked on it trade someone or sell it and use it to make buying a new cheaper..

No, I can get into fastboot and that is it.
But everything I try in fastboot gets rejected, since it says the phone is locked.

Does the bootloader screen on the phone have the option to boot into Rescue. This has a ADB connection but I am not sure if adb sideload works

Really mad that Google intentionally locks phones this way, turning them into completely functional, but useless piece of junk. I guess that's late stage capitalism for you xD

Google is not responsible for phone's with locked bootloaders. They make the device with the specifications the carrier that sells it stipulates. Google themselves allows the unlock.

Iam guessing the same. Phone doesnt want to do anything.
And since i cant get into the phone to oem lock i am stuck. Live in Denmark, so by law I havnt voided the warrenty by rooting.

Pixel warranty is always valid even if you unlock and root. Google doesn't void the warranty. Go to Google pixel support page. Find warranty and act as if your submitting a RMA and it will tell you after you enter the device IMEI how long your warranty is valid for

If that were true. Android flash tool https://flash.android.com/welcome
Would work as it's the same process for the browser to flash the very same file. Motorola allowed signed factory img on locked. Google had never allowed that in fastboot as far as I am aware

All you need to do is go here Factory pixel firmwares and scroll down to pixel 7 panther assuming you're not on the pro (cheetah)
-select the latest version for your model whether that's Verizon or whatever if you have the carrier unlocked one like myself just choose the Feb firmware that doesn't have a carrier name at the end of the firmware number (you should have your phone plugged into your PC and in fastboot mode) click flash and follow the steps. These are Googles factory images so it doesn't matter if your bootloader is unlocked or not as long as you choose the latest version and the correct version for your phone. Tbh you can't really brick the pixel 7 as long as you have a PC and are able to put the phone in fastboot mode (holding the volume down and power button while powering on)
-Anytime you run into some kind of bootloop issue or wanna get rid of root flashing the stock firmware from this website will factory reset and revert your phone to the way it was the very first time it was pulled out of the box and powered on. If you have already tried this and you know forsure you did everything correctly then I must admit I have never had this happen and I'm someone who flashes custom roms and goes back to stock to get the latest security update just to turn around and flash another custom rom right after lol. If you need any help or advice feel free to pm me whenever. I have been rooting phones for a long time and have to say that the Google pixel is by far the most user friendly phone I've ever owned when it comes to custom rooms, rooting etc. You can ALWAYS go back as long as you know what steps to take. Sorry for the rant especially if you already figured it out.
Happy Customizing!

Their bootloader is locked. You cannot flash a factory image like that with a locked bootloader. They also turned off OEM Unlocking in the developer settings. If they had left this enabled they would be able to use Android Flash Tool as that tool will unlock your bootloader if OEM Unlocking is enabled.

This wouldn't be Google, they basically encourage you too unlock the bootloader and root if you want as they give you all the tools you need and factory firmware options to go back if you make a mistake. Tbh if you are able to unlock and root the phone to start then you can go back. Even with a locked bootloader you can always flash the latest factory image on googles dev website, you just can't downgrade firmware or install different carrier firmware without the unlocked bootloader. If we really wanna poke at some phone developers I vote Samsung as I have had multiple people ask me to root their phones and if it's a US snapdragon version it cannot be done its so frustrating lol thanks for letting me vent, have a great day if you have the the carrier unlocked dev edition of the pixel 7 and ever need any help feel free to pm me. I have been rooting and romming pixels for a long time
Edit: I was not aware you couldn't flash the stock firmare using googles dev page without oem unlock. I apologize for jumping to conclusions. I thought I had every possible bad scenario happen to me by now but apparently I learned something new today.

Dude. You cannot flash factory images of any kind on any Google phone with the bootloader in locked status. Please stop giving false information on here. If you want to talk up Samsung do it on a Samsung post. Let's not confuse everyone please

To use Android Flash Tool, you have to have OEM Unlocking enabled in Developer Options for it to be able to unlock the bootloader.
To flash the factory image in fastboot you must have an unlocked bootloader.

Okay my bad you are right fortunately I have never had this happen. And like someone else said if he can't get into recovery then he can't sideload a factory ota... sorry I'm at a loss on this one. Some custom roms use "fastboot update file.zip" would that do anything in this case or would that command not even work with a locked bootloader I'm assuming. I apologize for trying to act like a know it all I've just never heard of this happening
