New Nexus 6 stuck in a bootloop trying to update to 5.1, please help.

Hey everyone I'm looking here as my last resort before sending my phone back to Motorola.
Bought a Nexus 6 from motorola uk which was delivered yesterday, switched phone on and all the Google apps on the phone updated, then had a notification OTA to download and install android 5.1 which I did, towards the end of the install process I had an error with the green android and a red exclamation mark.
I powered the device off with the power button and it turned back on and ever since it says "Android is starting" "Optimizing app 1 of 125" once it goes through all the apps it gets to the android boot screen then just goes back to the "Android is starting" "Optimizing app 1 of 125" over and over and over. (Infinite bootloop)
Pointers: The phone is not unlocked or rooted as I'm a noob its just fresh out the box, also I never opened/unlocked the developer options.
I have tried various recovery mode fixes, wiping cache and wiping all data and then rebooting the device with no luck.
Is there anyway I can hook my N6 up to my computer and fix this with a tool kit etc? I'm willing to try but I'd need basic instructions and reassurance it wouldn't muck up my warranty if it didn't work as my only other option is to exchange for a new device.
Any help, advice etc would be hugely appreciated. Thanks

Read the guide on how to fastboot flash a factory image. No toolkit necessary.

Would you mind posting a link to a guide? I forgot to add that I don't want my phone to become rooted by trying to fix this issue, I want to keep it stock like it was, also does not have developer options enabled stop me from going further.
Sorry for the questions I'm a noob to this and quite anxious.

If you connect the phone to the pc is it recognised in bootloader mode? Do you have adb installed onyour pc?

I've made the fastboot adb folder on my PC and attached my phone whilst it was in bootloader mode, I types in the command box adb devices and there is no list of attached devices.
I presume this is because I didn't enable developer options or USB debugging?

When in bootloader mode type : fastboot devices
-Edit- just read that your bootloade is still locked so i`am afraid there is nothing you can do to fix the issue as you cannot flash firmware with a locked bootloader. Best is to claim warranty because of a software issue while updating.

Thought this would be the case, I went into adb fastboot and typed in fastboot devices and its showing some letters and numbers next to fastboot on screen if that helps.
In the future I presume I should make sure to enable developer options first so I can get out if this mess?
Also would it be best when I get my new n6 just to sideload the latest update marsmellow by getting the factory image from the Google website? Last question can I skip from 5.0 straight to 6.0 sideloading or do I have tobdo it one at a time?
Thanks for trying to help matey

Next time enable usb debugging and ENABLE OEM UNLOCK, both in developer options. You can flash the latest firmware available directly in fastboot by flashing the individual img files.

It says this on my Nexus 6 phone screen.
Unlock bootloader?
If you unlock the bootloader, you will be able to install custom operating system on this phone.
A custom OS is not subject to the same testing as the original OS, and can cause your phone and installed applications to stop working properly.
To prevent unauthorized access to your personal data, unlocking the bootloader will also delete all personal data from your phone (a "factory data reset".)
Press the volume up/down buttons to select yes or no. Then press power button to continue.
Yes (Unlock bootloader, may void warranty)
No. ( Do not unlock bootloader and restart phone)

Sure, but first we have to get the phone working again,

Mi5 dead! please some ideas!

Hi all,
I going to tell you the complete story and any ideas orsuggestions will be appreciated.
I bought my mi5 in July. It came with a fake ROM but Ichanged it to OFFICAL GLOBAL STABLE .
Since then, I used the device perfectly fine, and follow theMIUI forum regularly.
Then in November I applied for betatesting Team and theyaccepted me. As my bootloader was still locked, I tried option one from abovetutorial, so I directly downloaded in my phone the GLOBAL DEV ROM and Ichoosing the package I started using Nougat for about a month, more or less.
Then, the tragedy happened. I was in a bar, having my phonein my trousers back pocket, and I set down that way. One minute, no more. Thephone´s battery was around 70%. When I realized I quickly took it but it wasnot able to turn on… Nothing pressing power volume + or any combination… I came home and let it charging all night (wallcharger) and nothing the morning after.
I tried to connect it to my PC but nothing happened in the screen,but pressing Power Volume+ the Windowsdevice Manager recognized it as “Android phone”, so after reading some threads about bootloader issues I decidesto flash it. I requested permission and then flashed it with the latest CHINADEV version. The flashing was completed, but the phone still not turningon. NEXT STEP: Local Technical Service.
They had my phone during a week. They tried to change thescreen, nothing, the battery nothing, and I don’t know which other tests theyperformed but they called me back to tell they were not able of doing nothing.
Having the phone back at home, now I was not able to get thePC seeing it as Android phone again. Nothin. Desperate me, I continued to read in internet and found in XDA a video where basically, you open the phone (remove back, and some screws),short two pins, and the PC is able to see it through the Qualcomm USB driversin EDL mode. Then flashing IS POSSIBLE. That is true. I am able to flashing,and I have tried CHINAs, GLOBAL, older ROMs about a dozen. Always the flash processsucceed, but the phone still not turning on.
After flashing I let the phone the whole night plugged inthe PC usb. Nothing
Now is plugged again to the wall charger, but nothing.
There are many threads with different solutions, so guys,please, anyone with a good idea to try??
Many Many thanks in advanced

https://forum.xda-developers.com/mi-5/help/bricked-mi5-t3528810
Read this and
Use only the versions mentioned

this device is just a chinese junk i regret bought it , just after 2 days i bought it got hard bricked .
anyway flash 7.2.4 and if phone didnt boot use 3 button ( up + down + power ) for 1 minute or more and it must boot , it did work for me .

I just got brick yesterday and followed those instructions. It really worked. I was finally able to flash china dev 6.11.10. Latest dev said just "missed hello packet".
MiFlash version 2016.04 and china dev 6.11.10 was right combination for me. I connected Mi5 to PC while pressing vol- and power buttons, then I released them. I opened miflash, selected rom and chose "flash all". Flashing was completed. I tried to power on my phone pressing power button but nothing. But when I pressed vol- and power, I was able to get to fastboot mode. Rest is history. I flashed TWRP, booted to it and flashed LineageOS again.
Hope it works for you too!

Yup..it's weird thing...i suspect there's a hardware issue too..
But anyway..did you already tried to flashing fastboot rom with QFIL (qualcomm tool) too..?, if not yet..just try it..you can follow tutorial from this youtube here , just bypassing the step for installing any driver if your phone already detected as qualcomm port in your pc.
I try this method to get back my friend Mi4c from dead with condition like this too..just edl or qualcomm port while connect in device manager, then after flashing with this tool..i've try to power on with vol up + power and repeatedly vol down method above..then mi logo appear.
Hope your phone get back turn on soon..

You can try this official global stable fastboot rom that's still based android 6.0 here
If above direct link doesn't work..just visit this link , then choose "Xiaomi Mi5 Global Stable or China Stable Version Fastboot File Download..
If getting error while flashing..just put extracted folder of fastboot rom in the root of your system..ie C:\[folder_fasboot_rom]

Hi all,
After a million tests, now the phone is able to go to fastboot mode easly just pressing power&volume- (even having a black screen...) Any idea to see if this is still worth to fight?

Just try typing command "fastboot oem device-info" to see the status of your bootloader...is it still at unlocked or already relocked..?
If still at unlocked state..you can flashing fastboot rom with miflash tool.

6: connect your phone & select flash all (1st option from the left, bottom of MiFlash tool)
This might take a few tries (example - you might receive "missed hello packets)
Once you're done, you can stay with the China Dev, unlock the bootloader & flash a xiaomi.eu rom, or CM.
Good luck.

Endless bootloop, I need help!

Hi, guys. Yesterday I decided to change my phone's firmware, so I flashed a LineageOS ROM. Of course, I have unlocked the bootloader. And everything was fine. But I always wanted to use Android Pay, so I've decided to relock bootloader to make it work. And now I have so called "Red State":
"Your device has failed verification and may not work properly".
And then, the loading stops. No effect. Just this screen.
But the main problem is that I don't have any access neither to recovery, erecovery or fastboot.
Any key combination makes no good, the phone just boots to this screen.
I've tried to drain the phone's battery and plug it into computer, but it didn't make any good.
Is there any way to recover my phone? Or it's already a hopeless brick? Please, help me, I've spent two whole days on it.

why you lock bootloader when it has wrong recovery? you should have had installed stock recovery before locking device.

Try connecting usb to phone (don't connect with pc yet)

Xiaomi has auto bricked after update- need help

Hey guys, i have MI A2 cellphone, and after auto update programmed to three hours the smartphone show "AndroidONE" logo and then shutdown, i tried "Fastboot oem unlock", but it is my output:
PHP:
C:\Users\Lucas Daniel>fastboot oem unlock
FAILED (remote: 'Flashing Unlock is not allowed
')
Finished. Total time: 0.000s
. I'm desperate, I do not know what to try anymore, I believe I do not have unlock OEM activated, someone can help me?
Sorry for bad english, i'm from brazilian.

@LukeSkyPTBR
It's a well-known issue. One update was revoked as soon as Xiaomi has found out about phones bricking once it's installed. There's no way you can fix it by yourself except if you have ordered your phone from China (and so no warranty you have) and have experience in disassembling phones. There's a thing called test-point, do some research if you are self-assured in that area. Otherwise let your authorized service center make everything for you. It is a warranty case, either way.

Thanks, looks that, unfortunately, my unique solution is test-point for activate EBL Mode... I will leave the topic open for the case of i get other solutions... after 3 days, if not get, i will close and the unique solution will really test-point.

Try rebooting it a couple of times and see if it boots. Or plug it to a charger and try booting it once it starts to charge successfully. If all fails, flashing via EDL might be your only option.

Try rebooting more than couple of time. Phone is supposed to switch to the other slot of A/B where original ROM (before update) resides. When it finally boots, get developer rights, switch on ADB Debugging and OEM unlock, thus next time update soft-bricks your phone you'll be able to unlock (or even better unlock immediately after successful boot not to loose your data in future).

Isnt Fastboot OEM Unlock command deprecated ? Shouldn't you use the unlock / unlock critical command ?

How can I do it? I leave the phone in the charger for a long time? Or do you need the power button for a long time?
I tried to press the power button for 2 minutes and nothing happened.
When i leave the smartphone on the charge, after 50 minutes, show for me 100% percent, so, i pressed power button and the screen stayed lock in "AndroidONE", nothing happened, until try again press power button.

I can enter fastboot mode, but this is not enough to do run commands up. I would need unlock bootloader(OEM).

If you can enter fastboot then you can go to EDL mode by typing 'fastboot reboot edl' and then use QPST to flash the latest stock rom.

Do as tabun1994 said.
This will hopefully get the system up again.
The commands I wrote would unlock the bootloader. What else could I have meant?
If you succeeded with tabun's method, then you probably would only need to enable "USB debugging" and "OEM unlocking" in the ROM's developer options (which you'll enable by hitting "build number" in settings like 10 times or so).
Then you would connect the device and accept the 'trust this device' warning.
After booting to fastboot now, the commands I wrote should work and unlock the bootloader (if you even want that when your system is running again).

This command needs OEM Unlock :/
this is my output: fastboot: usage: unknown reboot target edl

The test point method is actually easy , you have to dissasemble the display , easy procedure , remove the battery and short the two test points with tweezerz or something ,and in the meantime you plug the usb cable into the computer. It should install the Qusb_Hub drivers , and with miFlash you should be able to reflash the firmware . I bought a phone that was in this state and fixed it using these steps.

No more solutions, I will do the test point method, thanks to everyone who tried to help otherwise.

No it doesn't, i have tried this method on locked bootloader, go to this link - https://forum.xda-developers.com/an...e-how-to-reboot-to-edl-fastboot-t3394292/amp/
And download the fastboot_edl.7z , your phone will be in edl mode, I think you don't have the proper platform files which has caused the problem.

No it doesn't, i have tried this method on locked bootloader, go to this link - https://forum.xda-developers.com/an...e-how-to-reboot-to-edl-fastboot-t3394292/amp/
And download the fastboot_edl.7z , your phone will be in edl mode, I think you don't have the proper platform files which has caused the problem.

Mi9 Global - Accidentally locked bootloader and stock in recovery/fastboot

Hi,
Recently purchased a Mi 9 Global version, got the OTA update to MIUI 11, and everything was well. It is a superb phone, but I like to have root on my phones (mostly for Adblocking and System2, better control overall). I tried to install TWRP (custom version for Mi9) because I wanted to install Magisk/Root or try a different rom eventually. Anyway... I made a huge mistake. After trying to reboot, I noticed things had gone wrong, and was stuck in a boot loop. I guess I panicked and tried to flash the phone back to the latest global MIUI rom (Version 11, Android 10, from official site), using the Xiaomi Flash App but I did not uncheck the "clean and lock bootloader" checkbox on the bottom right of the app, which is somehow enabled by default. The flash failed at that time, for unknown reason, but it seems like it succeeded in locking my bootloader, with an empty partition, except for fastboot access and Mi Recovery module. I have to admit I've always been pretty lucky with all my previous flashes on other devices, and I guess I got a little careless. That was pretty stupid of me, in retrospect.
Since then, I am stuck in either Mi Recovery or Fastboot, and it seems that my originally Global Mi 9 with unlock bootloader has now a locked bootloader. Any attempt at either using the Xiaomi Flash utility gives me an error message ("Erase boot error"), and if I boot into Fastboot and try to flash TWRP, I get the "Remote:Erase is not allowed in Lock State" error.
From what I understand, my options are pretty limited now. The phone is still powered on, stuck in Recovery mode and rebooting every 5 or 10 minutes by itself (probably a way to avoid screen burn-in?), but I can't seem to be able to shut it down in anyway, as there are no fastboot commands to send a shutdown signal. And no matter what button combination I press, the phone always ends up rebooting.
I tried the Xiaomi Unlocker utility, but it needs the phone to be out of recovery to check the credentials binding the phone to my account. All data on the phone has been wiped already, so that's not an option. Two options I have seen :
1. Open the battery cover (required a heat gun and risky), to short some pins and try to flash while there is a short to circumvent the security. I'm not that brave yet, and since the phone is still running and has probably about 80% battery, I don't want to use a heat gun on the device.
2. Shady stuff involving paying 30 or 40 Euros to a random guy who can somehow make everything work magically by remotely logging in on my computer via Teamviewer (Not happening in a million years).
I'm wondering if there is an alternative, other than bringing the device to an official Xiaomi store (I'm in Bangkok and they do have one official shop at Fortune Town), but even then, I don't know if they'll just tell me I got myself an expensive paperweight.
Any help/insight regarding this issue would be much, much appreciated!

Have you tried to press and hold power+vol down when your device reboots? Just before it turns on.

Every possible combination on reboot will either bring me to Fastboot or Mi Recovery. I have wiped the data partition, there is no OS on the phone as of now.

So xiaomi unlock utility can't unlock bootloader in fastboot?
May be try to use xiaomitool v2.

Xiaomitool V2 is completely useless. The "My phone is bricked" option is not implemented, and I cannot boot into the OS, unfortunately.

To enter fastboot mode, long press the volume down key and the power key. Then unlock bootloader with Xiaomi app.

I have managed to enter fastboot mode, as described in my initial post. The problem is that when I try to flash, I get the following error: "Flashing not allowed in lock state".

Yep, but it has unlock option in the normal mode and it use scripts made by tool developer, so it worth to try.

From what I understand, the "normal mode" needs the tool to be able to access the OS while it's running. I don't have an OS. I will give it a shot tomorrow (3 AM here, exhausted, and don't want to boot into Windows again!), but my hopes are not so high. Anyway, thanks for the help, much appreciated! Will let you know what happens! Cheers!

Unfortunately, this is not true. I have downloaded an old version of Mi Unlock (2.2.406.5), which is supposed to work with Fastboot mode. The result is "Couldn't unlock --> Please download the latest version". And the latest version needs to access the OS to verify the Mi account credentials. I don't have an OS installed. So this won't work. Thanks for the suggestion though!

I came across this Mi8 thread, not sure if it's possible on the Mi9, but he seems to have been able to flash it through EDL mode, you might ask him the question: https://xiaomi.eu/community/threads/mi-8-bricked-from-nowhere.55723/#post-543605
There's also this Mi9 thread: https://forum.xda-developers.com/Mi-9/how-to/unbrick-mi9-bootloader-locked-destroyed-t3924966
