Nexus 6 Unable to Boot - Nexus 6 Q&A, Help & Troubleshooting

As above, helping an acquaintance on a local forum to post this. Not 100% clear how it got to this state, from what I know his phone had issues, and he tried to flash back to factory settings using Wugfresh. It worked, but after a while he started seeing this issue out of the blue.
The phone boots up, after the Google logo and the dancing dots, the screen shows this weird confetti before boot looping again.
Still able to get into bootloader, still able to get into stock recovery, fastboot detects the phone just find on terminal/cmd. I tried flashing factory images manually on both Windows 7 and on Mac OSX, the terminal indicated the flashing was successful, sending and writing onto the phone.
Since this is the first time i tried the N6, the only thing off was that when flashing system.img, it said "sending sparse data" instead of just "sending data"?

Anyway, i don't have the phone with me anymore, so it's more for my curiosity than anything else. I was thinking hardware failure (emmc?) of some sort, but would love to hear more input if any.
Cheers!

I had this issue once on my N6. I then flashed the cache partition (had skipped it earlier) from the dev images and it booted fine after that.

[RESOLVED] Unlocked XT1058; Bootloop & Failed System Flash

Long story short: Phone won't boot past "Unlocked Bootloader" warning; Recoveries won't stick; Unknown Error & Freezing when trying to Flash System.img
I own an ATT Locked Moto X, but went ahead and unlocked it by purchasing the oem code. No issues there.
I decided to go ahead and try rooting it too, and was able to flash TWRP as my recovery. Still, everything seemed to be looking good, until I tried hard rebooting (to see if root would last). Upon rebooting, I could not get past the warning sign, notifying me that the bootloader was unlocked. I waited, and waited, and restarted again, but all progress stopped there. I would be the first to admit that whatever happened was probably my fault; perhaps I flashed some files in the wrong order, or entered a wrong command into fastboot. I don't know, and frankly don't care. My only question is how to get out of this mess and back to rooting, or at the very least, back to stock ROM now that I'm unlocked.
Booting into recovery only leads to the red triangle over an open android mascot, with the "Android Recovery" title. So clearly TWRP didn't stick; I tried reflashing, but nothing lasts past reboot. Then I tried flashing Philz Touch instead, which, upon exit, notified me that root was not enabled. So I rooted, rebooted, and was finally able to see Philz Tough again, even though I still can't boot normally. That time, both Philz Touch as well as root seemed to have stuck.
With that minor victory I downloaded the latest firmware for my model and tried to flash the components over, thinking I had somehow corrupted the existing OS files, but here's where it gets particularly frustrating. I am able to flash every file except for system.img, even though I am using moto-fastboot, which I understand is a common mistake. I get no specific error code, simply "Unknown Error," upon which the phone is frozen in fastboot. The phone remains unresponsive until I hard reboot [back into fastboot], and see that, once again, Recovery is back to stock. So now I'm baffled. I can't seem to find a way to flash the system file, factory resetting doesn't work, and my recoveries are constantly reverted back to stock. Does anyone have any advice, or suggestions for what I could try next?
You try RSD lite?

I was already downloading it just as I saw your post, as my last-ditch effort. It also failed, but it gave me "Unknown USB Error," which is all I needed, it seems. I tried a different USB slot on another side of the computer, and lo-and-behold, the flash finished.
I'm not sure what saddens me more, the fact that I pushed off making this post for hours, only to have the solution less than an hour after I do, or the fact that I never thought to try a different USB port... In any case, sorry for the uselessness of this post. I think I'll save rooting for another day though...

[Q] HARD Bricked Nexus 6 PLEASE HELP!!

My motorola Nexus 6 won't turn on, when I try to power it on, it shows the Google sign then shuts off immediately. When I plug in the charger from a complete power off, the white battery sign keeps flashing, it shows for 1 second then shuts off then repeats the cycle of showing the battery sign then shutting off. It boots into bootloader/fastboot mode fine, and I have tried flashing the factory image, it flashes fine but it still shuts off immediately while showing the google sign. It won't even boot into recovery after the flash, it just shuts off after the google sign. This isn't my first nexus, in know that flashing factory image should fix 99% of issues. Please help.
P.S I didn't purchase officially from google or Motorola, bought it from a guy who claimed he bricked it trying to install a font pack so I figured let me buy it and restore factory image. Didn't work. I tried flashing manually, the process went fine, but it it still turns off at google splash image. I tried Wugfresh toolkit also to no avail. He said he rooted it, installed custom recovery and euphoria os rom. Then he installed the fontpack, it told him to reboot to apply changes, and it wouldn't boot past google screen after that. It doesnt even get to the boot animation. It just shuts off. When its off and u plug in the charger it does the same thing, you just keep seeing the charging symbol over and over because its constantly rebooting. Its a T-Mobile Nexus 6 BTW, model number XT1103. I spoke to my friend who has a local repair shop and he says there is nothing out for his z3x or his other boxes for the nexus 6 because it is such a new and rare device. His theory is that the partition tables have been corrupted somehow and need to be rewritten manually. Please any help would be appreciated. I can promise a hefty $$ reward for any individual that helps me recover it to a working state.
can you get a custom recovery on successfully.........?
did you flash the stock image manually?

Yes I tried pushing the stock recovery individually and it succeeded in the command prompt, but won't enter recovery, just shows google and shuts off. I tried pushing twrp too but same outcome. Yes I had flashed the stock image manually, everything flashed well from what the command promt said, but when it should reboot to recovery after flash to wipe, just shuts off.

Please! Anyone!
by manually do you mean flashing all the separate parts of the stock image separately, system, boot, recovery, cache and so on..........
I don't know what else to do after going through with that process.....
Make sure you have the latest fastboot by updating SDK Manager. Then reflash bootloader then reboot back to bootloader to reset. Then proceed to flash each partition again. Directions below.
fastboot flash bootloader bootloader.img <-- rename bootloader to this to make it easier
fastboot flash radio radio.img <--- again rename to make easier
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fasyboot flash system system.img
Hope this helps.
I'm a total newb here so take what I tell you with a grain of salt. I had your exact same problem on my Nexus 5. Every single thing you just described is what happened to my N5. And just like your N6...I was able to boot up into recovery (stock and TWRP), I was able to flash all the things manually and even used Wug's NRT. But then whenever I tried to actually boot up the device it could never pass the Google logo....basically EVERYTHING THAT IS HAPPENING TO YOU.
What I did to fix everything? Changed my battery. Sounds stupid and totally irrelevant but that did the trick. When I opened up my phone I noticed my battery had a nasty bulge and realized it was defective. Bought a new one for $25 and have never had any issues ever since. I suggest you look at your battery and see if that is the root of your problem. I have heard of the N6 having some batteries expanding and causing the back covers to pop off...this could be related to your problem.
Like I said I am a newb and thought I'd share my experience in the hopes it solves your problem.
Good luck buddy! :good:
my N6 is actually away getting repaired for the exact issue you described, expanding battery [assumed], and cover coming away from the bezel.....
I believe though that if you keep the device plugged into the wall when trying to boot up with this battery defect it will get through the boot, at least in the beginning anyway....
I believe also that if it was a battery issue the device would power off first, as opposed to just sticking on the Google logo.........

Thats too bad. Maybe the device is hosed. RMA for a new one.
Same thing happened to me. As soon as I updated to the newest version of fastboot on my computer, everything worked...

[Q] So A Funny Thing Happened While Flashing Stock Recovery...

Hey All,
I'm set up, and use my MotoX (XT1060 DE, VZW), in much the same way as I've read Kid Joe does: I flash twrp (because I have to---can't just boot it) and root so that I can run basic apps like Ti Backup, WiFi Tether, and Root Explorer. Nothing more.
I went to flash the stock recovery using a computer running Debian Wheezy this morning so that I could update to end the OTA-nag madness, and I used the Linux/fastboot that came with the stock ROM zip file I got from VZW upon request some time back.
Anyway, I got a message that I'd never seen before and wondered if anyone else out there had seen it. Specifically, I did the following from a non-root account on my computer from the directory where I'd unzip'd the ROM archive:
$ sudo Linux/ fastboot flash recovery recovery.img
The feedback report stated something like: "Variable Undefined..."
When I looked at my phone, which was in the bootloader, I saw a couple of getvar variables reported along the lines of "..max_download_size..." something or other. I'd never seen that before as, up till now at least, I don't recall ever using VZW's version of fastboot.
Both my computer and my phone reported that the recovery partition had been flashed; and, when I boot to recovery, it *looks* like the stock recovery, but I'm not exactly sure that it is. Why? Because there is one little issue that makes me wonder if all is well: When I boot my phone to recovery and pick the "Wipe Cache Partition" menu item, the phone shows a spinning lattice-orb in the open robot door, along with "Erasing..." underneath, but it never comes back from that; and I've waited for as long as seven or eight minutes for it to do so. I have to hard reboot the phone by press-and-holding the power button to turn it off, then powering it up normally.
Has anyone else out there ever seen any of that behavior? I would really appreciate it if you'd let me know about it...
many thanks,
john

Maybe it is some partition that was been corrupted or something like that, it happen to me on a zenfone 5 that weren't able to mount /cache but after a wipe he booted normally

Well im not 100 percent sure but I recently rooted my 4.4.4 phone no boot loader unlock and also on at&t. I had to flash a non ota update first and I had to remove something in the updates files that said max download size before it would work.
Hey Guys,
Thanks for the suggestions and feedback!
I don't have a clue as to why that message was coming up. I guess it's possible that both versions of fastboot that I have, VZW's and Google's, are somehow now out of date.
I actually went back and re-flashed stock recovery and got the same message, and I was still having the long wait time for it to wipe the cache partition. I actually waited longer when executing the wipe, and the phone eventually rebooted itself to its normal state.
I ended up flashing one of the later-model versions of TWRP recovery, v2.8.5. When I tried wiping cache from it, and, just as before, it wipes in seconds. *Boggle*
thanks again,
john

Issue returning N6 to stock - I've done it all

Trying to give the mother in law my old N6. It was rooted / bootloader unlocked. First attempt was to factory reset from within the OS. That worked fine, until I rebooted... it wouldn't boot.
I then downloaded the Shamu factory images from Google's website (shamu-n6f27m-factory-bf5cce08) and ran the flash-all.bat script. Multiple errors showed up during the script... but I chalked it up to ADB looking for boot slots etc, whereas this one has none.
Phone booted fine. Installed apps, set up the phone, power cycled it and promptly entered a bootloop.
Ran flash.all again, phone booted fine. Flashed TWRP, booted into recovery, checked things out in there (didn't do anything but flash the TWRP) tried to reboot, phone bootloops.
Flashed TWRP, booted into Recovery, tried to erase system, etc.... multiple errors again. Booted into bootloader, ran Flash-all... phone boots. Installed some apps, rebooted phone and bootloop again.
Then I did something REALLY stupid, I locked the bootloader from ADB. Now I'm on the bootloader, but can't OEM unlock because it's asking me to boot into the OS and enable the ability from Developer options.
I've no idea why this phone is doing this - booting fine into the OS once and then getting into a bootloop every time thereafter.
If anyone can shed some light on this, I'd appreciate it. Also, how in the hell do I unlock the bootloader now that I've locked it and I can't boot into the OS or run the Flash-all.bat anymore since it's locked?
Is your recovery stock? If it is, sideload the last OTA from Google and that should get you back into Android so you can toggle the OEM Unlock button.
Thanks. I was getting the "no command" on Stock recovery. Finally fixed this freaking issue after multiple flashes and wipes and everything else I could think of. Finally got it sorted.

So did you finally figure out what it could have been that you were doing wrong?

No. I could only assume I had messed something up when I was using it back in the day and really hosed something up. System wouldn't wipe, cache wouldn't wipe, userdata wouldn't wipe in "fasboot" just kept getting "unable to find XXXX".
So multiple flashes into TWRP and bootloops trying to really REALLY wipe the device finally fixed it. I just kept erasing / wiping every partition I could find in Stock Recovery, TWRP, and with fastboot commands. Finally I got them all wiped/cleared and was able to flash the stock OS back on and have it 'stick'.

Need help rooting-

I am having a hell of a time rooting this phone. (Motorola Nexus 6 XT1100)
I am trying to follow this guide: https://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
If anyone can offer some suggestions, they would be greatly appreciated.
I managed to get as far as unlocking the bootloader in fastboot mode.
The next step, obtaining root, is where all my problems started.
I downloaded CF Root and extracted the files, as instructed, allowed the root tool to run, (I'm using Linux, if it matters).
When the process was finished, and my phone attempted to reboot, it got stuck on the Google screen with the little lock (showing unlocked).
I allowed the phone to stay in this mode for around 30 minutes thinking it just needed time.
It never did anything. I attempted to let it try and start up again (a couple times actually) and it never goes past the Google lock screen.
I powered down the phone and restarted in fastboot mode, and attempted to run the CF Root tool again, with the same result.
I am currently stuck with only having access to fastboot.
I tried to flash a recovery and boot into that, but it won't allow that either. Perhaps this isn't even possible (YET), as it's not in the instructions to flash a recovery until after the rooting process, but I thought I would try it anyway.
I have tried flashing TWRP and Lineage recovery. No success with either, although the terminal is saying
sending 'recovery' OKAY
writing 'recovery' OKAY
But when trying to reboot recovery I get hit with
unknown reboot target recovery
Anyone know what's going on and how I can get this resolved? I just want to install a recovery and flash a custom ROM.
In that guide you can follow my journey to root starting in post# 929. I had & have had a LOT of help from my fellow XDAers. They're great & thank you all.
Thanks!
I'll check it out.
Boy, oh, boy.
I don't know what is going on.
I finally managed to get out of the bootloader screen.
I don't know what/how it worked. I downloaded Nexus Root Toolkit to a windows computer and tried the Flash Stock + Unroot option.
It keep saying waiting on device or device not detected or something ( I cant remember exactly, it was hours/many error screens ago!)
Next, I tried the option for Root + Add a Custom Recovery and directed it to where my TWRP file.
Again it acted like it was doing something. Even found my connected ADB device. Went through a couple processes, said it would need to restart a couple/few times. Everything was trucking along just fine until suddenly, it got hung up 'Waiting on device"
Not sure what happened, but all of a sudden, it could no longer find my device.
For chits and giggles, I decided to try and reboot recovery from the bootloader screen. I had attempted this many times and all it did was start back up in bootloader, BUT, this time, it actually started up in some recovery program I have never seen before. It wasn't stock and it certainly wasn't TWRP!
At this point, I hooked my device back into my computer running Linux and attempted to push TWRP, and reboot in recovery.
It worked!
Now that I had a recovery I was comfortable using, I proceeded to push my ROM.
Wanted to try Lineage with MicroG, but I am not advanced enough to go that route. I could not get a fake app store to work.
Guess I'll have to stick with what I know. I love the idea of MicroG, but it apparently doesn't work with Pure Nexus.
Anyway, just wanted to post some closure for this thread. I know the Motorola Nexus 6 is an old phone, but I like it. This is my second one. My first one, screen finally cracked and it was cheaper to just purchase a new one from Amazon than to replace the screen.
