Today I downloaded the new firmware update for the 5x. I installed using fastboot as normal, knowing that boot.img, vendor.img and system.img had changed.
I used fastboot to flash all three, then booted to TWRP and flashed SuperSU 2.76, ElementalX kernel and the AdAway file hosts.
The phone booted as normal and was running just fine for about 2 hours. Then, while playing music, I attempted to unlock the screen with the screen passcode. The device froze.
Attempting a reset only allowed it to get to the "Google" screen with the lock on the bottom, then the screen would go black. I could hard reset into bootloader mode. I attempted to flash back to stock, but the same freeze on the "Google" screen happened upon reboot.
Now, the device will not even get to bootloader mode. Holding the power + either of the two volume keys renders nothing on the screen, nor does plugging into USB on the computer. I'm fearing the device is hard bricked. Any recommendations?

Hi Tulsa,
Unfortunately, that post doesn't apply to this situation, as my bootloader is unlocked, and I can't even get to the stage of having the drivers recognize the phone, because the phone will not turn on to bootloader mode, recovery or download mode.
UPDATE:
The phone reached the point last night where it would not even power on, access bootloader or download mode. Any button presses/holds left the screen black.
Today, for whatever reason, the device booted into fastboot mode. I was able to flash the complete stock factory image for the August security update Android 7.0 - the first stable build. However, when the device began to boot, it once again does not get past the Google page with the lock on the bottom. The screen goes black after that without entering the boot animation.
I've called Google to get a warranty replacement unit sent.
I was having a similar situation last night, gave up after trying for a few hours...the googs is sending a "new" refurbished one. I had 1 month left on the factory warranty

Thanks for the reply, quadracer. I'll be taking the same path you are - Google already has the reorder on the way. Still trying to tinker in case there's a chance. Luckily, all the pictures from my engagement this past weekend were backed up to Photos or I'd be devastated.
I was just using my phone like normal today opening up the transit app at the bus stop and it randomly froze and restarted. After that, it only shows the initial Google screen and just keeps bootlooping, but never even gets to the part where the OS is loading (with the google animation). It was just on stock 6.0.1, MTC20K I think. Was not rooted. Bootloader was/is unlocked. Secure boot was/is enabled. It won't even go into stock recovery (when I select recovery it immediately goes back to the Google screen and continues as if I had never selected recovery). I have tried manually flashing each piece of the latest factory 7.0.0 build (NRD90S), but even though fastboot says everything was successful, nothing seems to have changed. Any ideas on how to fix this?
Same thing just happened to me. I have no root or anything but it will not boot the OS. I hope there is a fix for the problem because I really want to use the phone.

No recovery for you either?
What was the latest Build you had when it was working fine?
To get into the recovery plug the phone into your computer. Go into fastboot (vol down + power) and select the power off option. When it turns off or goes to the charging screen, hold volume up + power to boot to download mode. Once in download mode, turn the phone off by holding vol down + power, then go back into fastboot and you should be able to now access recovery mode. This is what I did, and then flashed back to 6.0.1 and it runs fine now. No Idea why going into download mode allows you to then access recovery and get one clean boot, but it does

Surprisingly, this worked. I forgot about download mode being an option. I also am not sure why this worked.
Edit: The phone boots, but is still randomly rebooting rather often. Not sure why, as everything was wiped and it should have been a fresh install of everything.
Another Edit: Back to boot looping/not getting to the Android loading screen. I didn't do anything other than let it download my apps. Maybe it is a hardware problem after all because it did successfully boot into Android a couple times.
This seems to be a common problem which I have, too. Looks like a whole series of devices had these issues. Currently LG is unable to repair my device because auf missing spare parts they say. So after effortless 3 weeks they will send my unrepaired device back to me with a letter for my dealer to get back my money.
Nice quality and service, LG - NOT!

That is actually pretty good outcome. Pixel phone is coming out soon.
Just had this happen today. Streaming music over Bluetooth and using another app, then tried switching tracks in Google Play Music and the app froze. Phone was unresponsive with app on the screen, then screen went off and wouldn't power on.
I finally got it on by holding down power for 30 seconds, but kept boot-looping to Google boot screen. I was able to get into fastboot mode and wipe everything and install the factory image. Still doing the same thing!
Just got off phone with Google. Told the rep everything I had tried and she is working on a replacement order. Supposed to call me back after chatting with higher level support. I wish they would just send me a new Pixel phone, or the 6P at least!
Ive had the same issue, where I just couldnt get passed the Google screen, the only solution for me to get back on to my phone was to let it happen until the battery died. After i let the battery die i turned it back on normally and connected it to my charger, it hasnt turned off since but im sure it will sooner or later
Edit: Issue is still happening but the only way for me to turn it back on is because the battery dies
This just happened to my and my wifes phones...all within a week of each other. I sent my wife's in about a week and a half ago to LG for warranty service. I am hoping that they are able to fix it...it is still in the 'repair' phase. I am trying to decide whether or not I want to send my phone in (which just died yesterday) before or after LG figures out what is going on with my wifes. In both cases, the phones were running fine and just shut down by themselves. The battery was not dead. Each time, the phone will boot to the Google screen, but then immediate shut down. I can get in to recovery and do actions within there, so I do not believe it to be a battery issue. However, as soon as you attempt to boot the phone, it will die.
Were you guys using stock setups or custom ones?

Its a 'known' issue. Google has confirmed there is an issue. Only solution appears to be a warranty replacement.

on both phones, bone stock. Only difference was I was running the beta before getting the stock OTA and my wife's was full stock and received the stock OTA.
I'm having the exact same problem here. Running Android 6.0.1, rooted. Phone suddenly turned off and won't start past the "Google" screen, except for once when it booted fully then immediately shut down, and three times when it loaded the boot animation and shut down. Bootloader is unlocked and TWRP recovery is installed. I can access fastboot but not recovery. I've tried the suggestion of booting into download mode then recovery again, but that didn't work. I have NOT tried updating to Android 7 yet, so this isn't the same boot loop issue faced by some other users. I don't want to try flashing stock yet and lose my data because I have a ton of Tasker profiles and tasks that I haven't backed up in months and I don't want to risk losing them! Serves me right...
Any suggestions?
Same HERE !!!!
the samed for me, and still now i can't light it up

In my opinion your EMMC probably died, but you can try reflashing factory images to see if it is some other problem.
I would only try LGUP as a last resort because it will set Allow OEM unlocking to false and lock your bootloader, making further experimentation difficult.
BTW IMO the Android 7 bootloop probably isn't related to Android 7. I think they are just saying hardware problem (EMMC failure) that happens to show up more frequently when you have large updates of OS.
The way Google worded it, it made it seem like Android 7 is killing some hardware because of some incompatibility with just some isolated hardware builds.
I would suggest you let it keep booting and flash some factory images and sometimes EMMC will come back briefly and boot. If it does, immediately backup as much as you can before doing anything else.
Same deal for me and they are sending a replacement. This is a MAJOR blackeye!
Is your phone under warranty then? I am having the same problem as everyone on here. I've tried everything. I bought the phone just over a year ago though, so am a little concerned Google will turn around and tell me it's not their problem... Even though this is clearly a fault!
My XL is stuck in a boot loop that I haven't found described anywhere. It begins with the bootloader unlocked warning screen then goes to the white "Google" boot screen, but within one second the screen goes black, waits about 10 seconds and runs through that cycle again. It also randomly (it seems) does the "Writing to EX4 file" screen before the bootloader unlocked warning screen.
It will cycle through this sequence forever if it's plugged in but when not plugged in it will seemingly power off after a random number of cycles. However, powering on does not require holding down the power button - it jumps directly to the beginning of the cycle, sometimes at the bootloader unlocked screen and sometimes at the EX4 screen.
At no point does my Windows 10 PC show the phone as being attached when plugged in to USB. Also, no combination or duration of the phone's physical buttons affect this in any way.
I was following the steps in this article and had just performed the second-last line in the post, "Reboot into the installed recovery." That's when the cycle started. Prior to the step "In TWRP, install twrp.zip" everything was working correctly, though I hadn't rooted yet, of course. I didn't reboot normally in between those two steps, so I can't say which of them caused the problem.
I'm running Android Update, 7.1.2 N2G47E and had been before beginning the procedure. It came from the OTA update and had unrooted the phone from the previous version.
Any and all help will be rewarded with 137 Antique, Pre-Web Internet Points and The Thanks of a Grateful Nation™.
I would fastboot latest factory image.
Just hold vol- when a reboot comes it will go into bootloader.

Sounds like you were coming from the April 2017 update to the May 2017 OTA update. The May update included a new bootloader which performs additional verification on the boot image. I suspect that when you installed TWRP and rebooted, the May bootloader detects the changes TWRP installation made to your boot image and aborts the boot process resulting in your bootloop. Additional detail and information can be found in the linked thread and solution should be towards the end of the thread. You have a few options I think (assuming you can get into fastboot/recovery mode) - you can temporarily resolve by reverting back to the April 2017 bootloader which does not have the additional boot verification procedure or you can follow the steps to flash Chainfire's VerifiedBootSigner.zip if you prefer to get fully on the May update (including the May bootloader). Details are in the thread below. Good luck!

Just started with me today too.
I cannot get into recovery or boot loader
rebooting using the hard button just brings up this Dump to EXT4 and then into the ROM that is havnig a ish ton of force closes.
My plan is to back up some stuff I need to copy off the phone and then start factory reset from within settings.
EDIT:
I was rooted running stock
All i did was run a backup in TWRP
issues started after reooting.
Once i factory reset and re Root i will see if I can restore backup, maybe

I had forgotten that after I booted normally just before installing TWRP, the May OTA happened to arrive and I went ahead and installed it. Then the problem started after I installed TWRP. I used @mikaole's advice and got into bootloader (can't believe I hadn't done that, given all the button combinations I'd tried).
I re-flashed the April update and now the behavior is exactly the same except that the white Google boot screen lasts about 5 seconds and after a few boot tries I land on the "No command" screen. That sits for about a minute and boots again, landing again on "No command." Power+vol-up gets me to recovery mode but all I can do is go to bootloader or get back to "No command." I tried a factory reset, same result. I tried re-flashing April again, same result. Now I think I have the May bootloader with all else April.
I ran this:
Code:
fastboot set_active a
because I noticed that flashing the bootloader was always going to b. After flashing the bootloader again and seeing it go to a, the phone boots normally. I'm going to let the May update happen and wait to root again until after that.
One thing, I don't think the link you provided is the one you intended - there's none of the info you said would be there.
This has been very helpful. You and @mikaole got me through this. Thanks!

They flashing all the parts of the image manually. Something like this happened to a buddy of mine and using the flash all wouldn't fix. He couldn't get the device to boot until he did all the images manually.

Hey guys, this is the only thread thqt i found here on XDA about pixel and pixel XL bootloop issue.
I'm about to buy a used Pixel 1st gen phone for really great deal, because it is in this bootloop. As the owner sad, it was on the Oreo upgrade. I'm wondering if its possible to fix it... What you guys say?
Thanks!!

Well that depends. If the owner unlock the bootloader and then relocked it it could have screwed it up depending on what he was doing with it at the time resulting in a bootloop that cannot be fixed because it's hard brick now. I say can't be fixed only because the only way to get it fixed as far as I know is to contact someone here on the forums I'm not exactly sure who it is but they do fix hard bricked pixels for money. If I were you I would try and figure out if that's the case before buying it.

Yes, that's my biggest fear right now... He sad he never had done anything like root or custom rom, he just had done a system update and the phone never boot correctly again.
I have a little bit of knowledge in android, i was thinking if just putting a custom rom it wouldn't solve, because i had other devices that i had put in bootloop and i was able to fix it just putting a custom rom...

Yeah if you can get into recovery you can side load things. And if you can get to the boot loader screen you're fine.

Hello, everyone!
The problem is that when booted, the phone only vibrates and turns off immediately. The screen never enables, LED for charging never enables. When connected to a charger, just vibrates. Tried to follow the steps here : installed the Soc driver, plugged the phone, tried to power it off - device manager recognized the phone for a couple of seconds and then it's gone.
Long story short: I tried to install official firmware upgrade using TWRP > Install > .zip. The installation was going on for a couple of minutes and then the screen blacked out. Since then, the phone does not boot.
So, I got bored of my Android 5 and decided to install a custom ROM, but I had to upgrade official firmware before that.
At first, I dove into how to install custom ROM tutorials, so I did the rooting first:
I downloaded a BootLoaderUnlocker program from the official Asus website and unlocked the BL. Then, I followed a tutorial for one-click-root, and succeded. Then I installed TWRP and flashed the Recovery to the latest available img for my phone and tried to install the Lineage OS 14.1 but got status 7 error, meaning something is incompatible.
This post states, that in order to install Lineage OS 14.1 I have to have a firmware at least MM 4.21.40.xx which is Android 6, so I went to the official Asus website and downloaded the Firmware upgrade. Since, I probably had the wrong BL at that point, I flashed the bootloader with TWRP for Z00A (Lollipop) 2.8.7.3 from here, which is the same website from which the post suggest to download a BL for MM (Android 6). I thought, since I currently have the Lolipop, should install the BL for that, just to be sure. Then I started the firmware upgrade, which rebooted the phone into the BL, I didn't think, and just pressed Normal Boot and the phone booted as usual in the old Android. Then I tried to initiate the instalation again but couldn't (it's supposed to auto-detect the file in the storage root), so I got an idea to just boot the Recovery, maybe it will continue. So, I did that, and the TWRP showed up (I forgot about it already and thought that the instalation would just continue), so I just pressed Install and chose the firmware upgrade zip manualy. The installation was going on for a couple of minutes and then the screen blacked out.
Since then, the phone does not boot. If I try to, it vibrates like it is going to boot, but then nothing happens (not even a logo).
I even tried to disconnect the battery: removed all the screws, removed the back panel and manually disconnected it. When I put it back the phone vibrated like it was going to boot, but nothing happened again.
P.S. I tried to boot into the Recovery, but that just does not work, and even did not work before the firmware upgrade (I googled, that I must press power and volume up and hold until the logo appears, but that doesn't happen).
upd: plugged into the charger, periodically shows the battery icon on the screen.
upd: I went to a service and the dude said I might have screwed up the `preLoader`, so some might say it's a disastah

So, I went to a service and turns out I messed up the PreLoader, that boots the BootLoader. Sometimes this cannot be restored and costs a bunch of money to replace the memory block, but I got lucky and got the phone repaired.
P.S. Do not install official firmware with programs like TWRP, use only your manufacturer's SoftWare
Hey, so I bought a new Zenfone 2 which arrived yesterday.
But it had only Android 5.0 on it with no option to update the system.
After some googling I found out, that I have got an CN phone, but have/need WW software.
So I tried to get Android M via this tutorial:
https://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556
I followed along, until point 4. I had no idea how to get the Firmware OTA on the phone now, as I had no option to access the phone storgae via PC?
So I thought, let's go into recovery mode, recover the system, put the OTA on the device first, and then follow the tutorial again.
But now, when I want to start the phone, this screen appears: https://i.ytimg.com/vi/T5GlOGbL4Lc/maxresdefault.jpg , then after 1-2 minutes it vibrates two times, and this screen appears again.
I think it's some kind of a bootloop, so I want to access the fastboot-mode to restore the phone somehow with a original firmware, but I can't access the fastboot mode anymore.
If I hold down [Power]+[Volume Up], the phone just vibrates two times and boots normally. If I hold down both, and release [Power] or [Volume Up] earlier (after around 5 seconds), it revolves in the same screen again.
So any idea how to save my phone?
Okay, with "xFSTK-Downlaoder" I managed to get my phone back into Fastboot Mode. Here is how to do it.
Then, post number 8 in this thread solved the problem.
I flashed a totally new Android 6.0 Marshmallow WW on my CN-Zenfone by erasing the whole memory of the phone, including recovery partition and boot table, and creating it new. Now everything works great.
If anyone needs help with this problem, feel free to contact me. (I hope I get email-notification if someone pm's me haha)
