Stuck at Google boot screen with unlock logo after marshmallow. - Nexus Player Q&A, Help & Troubleshooting

I downloaded the factory image from Google and confirmed that the md5 matched. I then used the flash-all batch file and I'm stuck on the Google boot screen and it never goes any further. I have tried manually formatting the userdata, cache and system partitions and then manually fastboot flashing the partitions inside the zip as well as the bootloader. Is anyone else experiencing this issue?

figured it out. flashed my TV with updated firmware and the issue resolved itself. this is such a great device but is so picky about HDMI ports and devices.

/sdcard unable to mount?

I tried encrypting my phone today while on CM10.1 and it rebooted and hung on the google screen for a few minutes so I held the power button and it rebooted and went back into CM10.1 except it said, encryption was unsuccessful and i needed to do a factory reset. So I let it reset, but it kept sending me to that page. So i booted into recovery tried to manually wipe it and it said /sdcard could not be mounted. I am currently using a linux toolkit and trying to push the google sock image, so far it has pushed the bootloader, boot, and recovery. I am sitting at system and thinking my phone is borked.
Someone else mentioned that they can't mount /sdcard .... are you actually trying to mount it?
Are you using fastboot to flash the appropriate stock files?
From bootloader: fastboot flash boot boot.img
fastboot flash system system.img etc... ?
Or running the flashall.sh script in the stock downloaded files?

Nexus 4 stuck on boot screen after update

Need some help.
I just sideloaded the 4.3 update to phone and now it's stuck on the 'X' loading screen.
My phone was rooted, but all stock (including the bootloader). I used the sideload ADB command and everything went fine, but the phone now won't boot.
How do I fix this?
did you data wipe(factory reset) before flashing?? if not, you have too.
I applied the OTA...didn't think I had to
Any idea on how I fix it now?
Really don't want to lose all my data

I do not think because you have to change recovery you must unlock the bootloader and unlock bootloader wipe the phone

no, its the data(and other stuff) causing it not to boot. same thing when flashing custom rom, you wipe when fkashing different roms. and going from android 4.2.2 to 4.3, theres many changes, enough to consider it a different rom.
Shoot...I should have done more research before doing this.
I did a factory reset through the stock bootloader...but it's still looping on the 'X' screen.
Can someone walk me through this or point me to a guide?
Bootloader is currently unlocked and I'm able to get into the factory recovery.

yea, the zip youd want to wipe data/factory reset, then flash the rom. dirty flashing wont help since the changes are big enough.

I bought my ole lady a Nexus 4 for Valentines day, anyway, today she got the OTA update and let it install the update. Now mind you she is 100% stock, adb debugging was not enabled, and her bootloader was still locked. (She would not let me touch her Nexus 4 lol) When the device rebooted it stuck on Android Upgrading finishing boot. So I said well let me see what I can do, this is what I did to fix it.
I use only Ubuntu so this may not work on windows i do not know. I Booted the device to the bootloader, connected it to my laptop via USB. I opened a terminal and typed in "sudo fastboot devices" and entered my password when promted and this gave me the device ID and fastboot letting me know fastboot was working. I then typed in "sudo fastboot reboot" and the device rebooted but was stuck on the bootanimation. I opened the internal storage up on my laptop in my file explorer and made a copy of her internal storage. Next I booted the device back into the bootloader then opened a terminal and typed in "sudo fastboot oem unlock" and the device gave me the unlock warning and the yes or no options. I selected yes so it would factory reset. After it did the factory reset the device reboot and booted to the setup welcome screen. Hope this helps others, also thanks to my good good friend Ljjehl for reminding me to use "sudo".
Edit: If you open the command promt with Administrative permissions in Windows this will work in Windows as well. Go to C:\Windows\System32\cmd.exe and right click on the cmd.exe file and select run as administrator. Then CD to the location with your fastboot.exe command. Thanks to another good friend TheBr0ken.
Thanks for the help...
I just ended up flashing each of the 4.3 components from the factory image. Just annoyed that I lost everything...
I'm stuck at the same screen. I received the OTA update, I didn't do anything special. My phone is unlocked and rooted (or WAS) but that was months ago, the rest is stock.
I think having encryption on my phone may have made it do this. I don't think Google anticipated doing the update properly for encrypted phones. Now I fear I've lost everything because even if I could connect, all data is encrypted...
similar problem
After starting to OTA update it was going smoothly, i was making breakfast, came back to find my screen at the "starting apps" screen frozen. The little circle that rotated wasnt doing anything so i left it there for awhile longer and still nothing. It would not move off that screen so i held power button down and restarted. now its stuck at the X screen also.
Yeah, I'm stuck there too. Already tried Factory Rest, didn't work. So what can I do?
I was on stock 4.2.2 and unrooted. I used the 'Google Services Framework' hack to force the 4.3 OTA update. The update downloaded successfully, phone restarted to apply the update and then restarted again. And now its stuck at the Google screen and keeps on restarting :crying:
I dont have the USB drivers installed on my PC too.
Same Problem
I have a nexus 4 (stock and unrooted),after 4.3 update,it is lagging during phone lock on/off (2 sec/5 sec).Hence I restarted my phone,and it stuck at "x" logo.Did clean data 3 times and then its working.
The problem is,in 2 days,I have experienced and done above thrice?
What could have gone wrong?
Hi guys,
I've just found how to correct this problem. All you have to do is to correctly wipe your phone before flashing factory image.
So :
Fastboot erase boot
Fastboot erase recovery
Fastboot format cache
Fastboot format system
Fastboot format userdata
I've just unbrick a n4 this way 15 minutes ago.
I have found the problem in recovery where you can see error log saying "cannot mount cache"
So formating correct the issue.
Hope it can help, fingers crossed.

[Q] Nexus 7 stuck at the google logo

Hello,
I've got a problem. On monday my Nexus 7 2012 (with lastest stock Android) froze and I had to reboot it. But then it got in a bootloop where it would boot to the boot-animation (the four moving dots) and then restart after half a minute. Then I went into the bootloader to switch it off. When I switched in back on it just got stuck at the google logo.
I tried to reflash the stock rom, but I haven't unlocked the bootloader yet and everytime I try to do unlock it, it fails with "unknown error code".
At first I used Wug's Toolkit. When that didn't work I used cmd, but that doesn't work either.
I would really appreciate some ideas to solve that
You dont have to unlock the bootloader to flash factory images.
You can flash it with fastboot or a toolkit.
Did you try to get into recovery?
Maybe you can wipe some thing like cache, dalvik cache and system,
And then install the firmware again.
I once installed a firmware without properly wiping and also got stuck in thjis animation logo.
After wiping in recovery and re-flashing the firmware it worked again.

As far as I know, you need to unlock the bootloader. Anyway, I tried a toolkit as well as fastboot via cmd but none worked.

In order to do anything useful in fastboot, the bootloader must be unlocked

I dont't have any custom recovery installed. When I am trying to access the stock recovery mode via the bootloader then I get to the Google logo and "booting failed" is written in the upper left corner.
My guess is that the emmc is broken
Google search android factory images, download the appropriate one for your device
Then extract contents and double click the flashall.bat
If this fails then chances are your emmc has been severely corrupted, I've seen a few get to that point with the booting failed and its 50/50 if they resurrect their device
Best of luck
(Oh and don't use toolkits)

Help help help with a hard bricked 6P

Hello guys,
I had my phone rooted with latest twrp. I flashed stock+ rom with Franco Kernel 25r and the A.R.I.S.E file for better sound. I've done the same set up minus the ARISE file and never had an issue.
well to my luck it kept bootlooping and I wasn't able to get back into my custom recovery. When I got home and got my hands on a pc I did a factory reset by manually flashing stock google img . I even used a couple tools since I ran out of ideas and still no luck.
I'm able to do anything through fastboot but I can't seem to get into my recovery at all.
Any ideas or tips of where I should go next?
Not a Hardbrick
As long as you can get to the bootloader mode, you haven't hard bricked your device. Hardbricking is a point where you cant boot your device and in to bootloader so there is no way to flash your device to a useable state.
Now as you can boot to the bootloader, just fastboot boot twrp.img and if you have a factory image zip, copy it in your device internal storage and flash it. Its that simple, provided you are already using an unencrypted boot.img in your current setup. Or else the next step is to flash an decrypted boot.img(you will loose all your userdata and internal storage data.). There are ways to mount the the encrypted filesystem if you are using a pin or password combo with your fingerprint. But without it its a bit more trickier so just for ease and if you dont have any inseparable data in your device now just flash a decrypted boot.img and then you can easily mount your internal storage to your pc and copy the factory image and the rest you already know..
At this point, I'd recommend a full reset.
Flash all the images in the latest Android M factory image (don't flash DP5 or similar N based ROMs): Recovery, Boot, System, Bootloader, Radio, everything.
Once you get stabilized and back into a working phone, then start rooting and messing around with kernels and what not.
To be completely honest, I've flashed nearly every ROM for the 6p, as well as my other Nexus devices, Galaxy phones, Sony phones, and no-name brands and none of those ultra modified kernels did any noticeable change. I tried the F2FS, NTFS, etc file system changes, tweaks to the governors and IO's, all of that, and found the stock kernel was the best. If a kernel with a different IO Scheduler worked even 10% better than the current implementation, and was just as stable, don't you think the Google/Android Engineers would've pushed that to live?
Currently running Pure Nexus July 23rd Update, everything stock that comes with it, Systemless Root/XPosed, and Viper4Android and have never had a performance or stability issue. I'd recommend you do the same.

First of all thank you for the response.
I've tried flashing the most current twrp and it seems to go through fine on fast boot but when I actually try to get into recovery from the device it will boot loop and just keep doing that.
How can I get into the phones storage through fastboot?
Where can I get the factory zip?
it feels as if everything seems to go good through fastboot but when I actually try to boot the phone nothing seems to work.

Thanks for the reply.
I've done the manual flashing already and flashed everything single item the most current factory image. Everything seemed to have gone through okay but when I rebooted the phone it was back to 0.
I'm actually considering getting rid of the phone now since it is my daily =/
Format each partition before flashing.
fastboot format <partition>
wait until it's done, then
fastboot flash <partition> <image>
Some partitions can't be formatted, which there are ways around, but try this first.
Just get to bootloader mode and try booting the twrp.img
fastboot boot twrp.img
From the twrp ui, go to advanced wipe and format your storage.
To mount the internal storage on your PC, enable mtp from twrp screen.
If U are using a decrypted boot.img, it will easily mount ur internal storage. Or try flashing a decrypted boot.img
fastboot flash boot boot.img
Then try the above again..

I flashed the twrp.img and it went through successfully at least on the computer it did but when the phone actually tries to get into recovery (twrp) it will start to boot loop and keep on doing that. I tried both an encrypted and decrypted boot img but it still made no difference.
I'm really going crazy over this

You need to explain more on what you actually tried here.
Just download the latest factory image and try to flash the latest bootloader using fastboot.
Then boot to the bootloader and try formating the device. Not wiping
Then you have to
fastboot boot twrp.img
I believe you have only tried wiping not formating. I faced similar issue before. But once I flashed a decrypted boot.img, it cleared the user data and then I was able to get to twrp.
Maybe your twrp img is corrupted if this didn't work.

i just flashed the latest bootloader from the most recent factory image and i did the command format user data and then tried the fastboot boot twrp and the phone will then try to get into recovery, the google logo comes up lasts a couple seconds and boot loops all over to where is says my phone cant be check for corruption
By now i should have been able to get into recovery and it wont go through

download a factory image and run the flash all file...... it should reboot your phone after 5 minutes and the issue should be resolved.. a hard brick would be a device that does nothing.... in this case i believe that you just didnt do something right.
Then download the latest factory image and extract it
fastboot flash radio.img
fastboot flash bootloader.img
& do a fastboot update the rest archive file as it is
This will flash the rom via fastboot& U don't have to rely on TWRP or CWM

I was really really hoping this would help. I erase/formated everything before flashing anything. I then ran the flash-all file and it took a couple of minutes and it said finished on the command box and my phone restarted and went into the white google logo and rebooted again with a bootloop. I waited around 15 minutes hoping it would start but it didn't.
It honestly feels as if the phone is not processing the full commands but on the pc it seems to go through successfully
is there a way to force an install of a rom and see if maybe a dirty flash over the stock one will allow it to start up?

Just unzip the factory image and there U can see the flash shell script files too. Open them in a text editor & U could see the exact command. In a factory img, they also do the same thing via script files. Flashing the radio & bootloader & updating the rest archive
so this is what I've done
I've manually flashed every file needed for the factory image from google.
I also tried wugfresh tool kit which is great but didn't help me much. I flashed stock recovery and treid to boot into to and nothing. I flashed a customer recovery and nothing.
It always does the same thing
the screen that says my phone can't be checked for corruption and then the google sign comes up stays on for a couple seconds and then it bootloops to the can't be checked for corruption.
I try to get into recovery using fastboot commands and the phone does the same exact thing.
I was even able to lock and relock the bootloader and I was able to successfully flash everything at least that is what it showed on the computer
so ive read almost every thread that had to do with bricking and I feel like an expert now but im starting to think it is done =/

Hey there. First off make sure to unlock again your bootloader. Then you may follow post # 10 of @Heisenberg 's flashing guide for our device.
First images to flash would be bootloader and radio. First flash bootloader, then make sure to issue the command adb reboot-bootloader. Then afterwards once the phone has rebooted back to bootloader, flash radio, then again do the adb reboot-bootloader again.
Once the phone is again back to bootloader flash the rest of the images except userdata. For the boot.img and recovery.img, flash the stock ones-don't use the decrypted boot.img and don't flash the twrp.img yet. Once all necessary images have been flashed issue the reboot-booloater command one more time, then on the bootloader screen choose the reboot option. Wait anywhere from 3-10 minutes for the phone to load. Let us know how it goes for you.

I tried this method a couple of minutes ago. I flashed them this same way
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader

fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
It does the same exact thing it will try and restart the phone, the message that says it can't be checked for corruption the google logo comes up and it repeats it self non stop.
This is what doesn't make sense to me.

This is weird. What version of the stock factory images did you flash? I've been using leviticus 1.3 since it came out and when i was still on stock rom. I switched over to cm builds and have been flashing every nightly since the 7/24th build, and in the process repeatesly reflashing the aound mod along, and i've had zero issues with the phone booting afterwards.

Bootloop With locked bootloader 7.0

My 6p is stuck in a bootloop. nbd90x build my bootloader is locked is there anyway to unlock from adb. I have already tried sideloading ndb90x through adb wipping chache and user data and still no luck. Help me Xda youre my only hope..
So you previously enabled USB debugging, how about OEM unlocking? If so, use 'fastboot flashing unlock' to unlock the bootloader. Note that internal storage will be completely wiped. Everything. Though with USB debugging enabled, you should be able to adb pull the contents of you SD card first. If you can unlock the bootloader you can try flashing factory images with fastboot. Otherwise, not much else besides RMA it with Google. There's been a few reports of stock N6Ps bootlooping. Haven't seen anyone post that Google denied the claim.
no bootloader is locked so cant flash using flashboot but debugging is enabled so I am able to use adb .
I know. What I'm asking is if you enabled allow OEM unlocking in developer settings? That doesn't unlock your bootloader in itself. You still need to use fastboot to do it. However if that setting IS enabled what you can do is... Use ADB to pull your internal storage to PC. Then use fastboot to unlock the bootloader and flash factory images. If the setting is not enabled, and wiping data and flashing an OTA don't work, I'm not sure what else can be done.
You can try downloading the 7.1 dev preview OTA and seeing if it updates whatever is causing it to fail. Other than those, RMA would be your best bet.
https://developer.android.com/preview/download.html#device-preview
After sideloading a ton of times between 7.0 and 7.1, one time i got it to boot up then i immediately enabled oem unlock then it crashed again... so now I am able to flash through fastboot although I havent been able to get it to boot again. Is it normal for bootloops to not get fixed by flashing?
Hijacking your post to report what is happening to me. I posted the same thing on the Android Beta program community on G+.
Have been using the latest beta since it came out on completely stock 6P (locked bootloader, unrooted). Everything working normally when yesterday around 10 or 11AM, phone starts to bootloop OUT OF NOWHERE, it was just sitting there on the table while I was working. I could still get to bootloader/recovery, so that was a bit of a relief. First thing I tried: clear cache, nothing. Then proceed to wipe/factory reset the device, to no avail. Immediately downloaded the latest factory image from Google's page, tried flashing it but couldn't since the bootloader was locked (OEM unlock option also disabled). Then downloaded the beta OTA and sideloaded it, process went through OK but device still bootloops. Tried sideloading the latest stable OTA but didn't work since it was from a previous build. Ran out of ideas. So there I was creating a thread on XDA for help while the device was still on its bootloop rush, about to hit the Submit button when again OUT OF THE BLUE SKY the device decides to boot itself back up. First thing I did was unlock the bootloader. Phone worked normally for 6 or 7 hours, when I'm doing something on it and then again, screen froze and bootloop starts again. This time I only reset the device and left the it bootlooping, after about 30 minutes it boots up again. I unenrolled from the beta and installed the latest 7.0 build. Everything working fine for the last 12 hours. Anyone have any idea on what can cause the device to bootloop like that? Never seen anything like it.
Yea I signed up for the beta program too do you have the link to unenroll? So you just reset and let it sit?
Here you go

do you remember what you did to get it to boot?

Well, that's the thing. Everything I tried didn't seem to work. I couldn't flash the factory image since the bootloader was locked. I was able to sideload the beta OTA but the device still bootlooped after that. So I just left it bootlooping and after around 20 or 30 minutes the device booted normally. I have no idea what caused it and what I did to make it work again.
P.S: device restarted 2 times while I was typing this.

If your boot loader is locked you are screwed, sorry to say, I would RMA it. Unbelievable an update can mess a phone up...that's why I always unlock the bootloader first thing and never lock it. I need complete control of my phone.
Edit: Only thing I can think of is delete the partitions with fastboot or adb and reflash factory image.
boot loader is unlocked now Ive tried flashing using the flash-all script but the phone still wont boot

As a last resort, flash all of the images manually with fastboot. This will wipe all userdata and completely format the SDcard. Nothing will be left. Extract the bootloader and radio images from the factory images zip. Flash them in fastboot. Reboot to fastboot again. Extract the next zip in the same folder as BL & radio images and flash the vendor, system, boot, recovery & userdata image files. Just for good measure, boot to recovery (stock Android recovery) and perform a factory reset & cache wipe. If the phone still fails to boot, your only option would be to RMA it at this point.
Note: As per Heisenberg's sticky thread, do NOT flash userdata.img if you have anything besides the 32gb model as you will only have the ~32gb storage available. If you're using a model with more storage, just use fastboot to format userdata but don't flash the image.
Ill try that.. but isnt the warranty voided because the bootloader is unlocked?

Not on a Nexus, no.
Added: I had to RMA mine after the phone got its first update. I unlocked the bootloader and stayed stock for a long time (until N came out). I took the OTA in About Phone and it applied with no problems but the phone would not boot. Factory images also couldn't get it running. Stock recovery and all. RMA'd without issues. I didn't tell them, just sent it in. If they tried to boot it they would've seen the unlock symbol. There's also a thread somewhere buried in the general section where someone called Google and asked and they confirmed to them that unlocking does not void warranty. I'll try to find it for you.

I also returned 4 faulty Nexus 5's (mostly screen artifacts) all unlocked with no problems.
