I've been watching several threads for the last few days, and have not seen this exact issue. I would greatly appreciate some help.
Device:
- Nexus 5X LGH790 32GB
- Stock bootloader / fastboot
- Never unlocked / rooted / etc.
The only advanced thing I've done is join the beta program a few months ago to get 7.0 early. Got that without any issue.
Issue:
I received the 7.1.1 OTA on the day it came out. Installed with no problems. The next day, the phone just froze in the middle of regular use. After about 15 seconds, it started boot looping to the Google splash screen. I can hold volume-down to enter fastboot, but when I select recovery mode, it just starts looping again. Pretty much all I could do was power it off. I did find out by accident that if I left it looping for long enough, sometimes it actually loaded normally (I even saw beta program warning/notice). But when I tried using it for more than a minute, it would freeze, reboot, and loop again.
What I've already tried:
- I tried using the WugFresh NRT fix softbrick method. I was able to quickly turn on debugging one of the times that I left it to loop. But when NRT sent a reboot the phone, it threw it back into the loop and NRT stopped recognizing the device.
- I tried to follow the unbrick procedure using a TOT file in this thread: http://forum.xda-developers.com/nexus-5x/help/tutorial-how-unbricked-nexus-5x-16gb-t3481766 But even after using LGUP, I still cannot even get into recovery mode.
- I filed a bug in the AOSP here: https://code.google.com/p/android/issues/detail?id=225802.
I'm at a loss here. On another thread, a member suggested this type of loop was a hardware/solder joint issue. I suppose that's possible... but man, what a coincidence that would be! Just now after the OTA the hardware fails? Any other thoughts? I'm pretty new to a lot of the terms/methods here, so maybe I missed something.
Thanks, DCK.
Update: I tried using LGUP again. The phone still gets stuck on the Google screen then boot loops.
Now, however, I am able to get into recovery mode consistently. Other threads have suggested doing an OTA sideload at this point. But I cannot seem to get my device recognized. The NRT shows no ADB devices connected. So I'm still stuck. Is there another way to try sideload?

Try fastboot/bootloader mode and fastboot flash the OTA manually.
Update 2: Seems like all the other things I tried over the last few days have caused various unofficial USB drivers to be installed. I've tried uninstalling most of them. I downloaded the google USB driver from latest SDK. But my 5X is still recognized as a Kedacom device when it is sitting at FastBoot.
However, I must have made some progress because I was able to start the sideload process. Unfortunately, I am now stuck on yet another error. The phone hangs at "verifying update package" and then after about 2 minutes... it reboots itself and starts looping again!
I thought I had it. So close. Now I want to throw the phone. Going to sleep, but would be grateful for any other suggestions in the morning.

use nrt to erase all partitions, then download 7.1 factory image, unzip and flash one by one the partitions.

Sounds like the boot loop issue many people have been having (the hardware/solder issue). It happened to me a few weeks ago after upgrading to Android 7.0. I got a replacement device from google.
If you're bootloader is locked, NRT or any other method to flash the factory image is not going to work. The only suggestion I have is to un-enroll in the beta program and hope your device will boot long enough to flash the ota Google will send the device to get back to 7.0. Note, this will wipe your device.

Same problem here. It can't be recognized after I reboot to fastboot. So I can't flash anything.
If the device isn't recognized try this http://forum.xda-developers.com/showpost.php?p=69273414&postcount=33. It's worked for a few of us with the same problem

Enter stock recovery then flash the full ota via adb sideload
I have updated my Nexus 5x to 7.1.1 beta and after a day it powered off and I got the infamous red led during charging. I was not able to turn the phone on even after leaving the charger on for some days. I thought it is bricked and left it alone connected to my computer.
However today, out of nowhere Google logo popped up. It was bootlooping, but I was able to enter bootloader and original recovery. I wanted to flash it from bootloader, but was unable, because it was still oem locked. And I was not able to oem unlock, because I did not do the required part in the Developer Tools menu. I tried to adb sideload OTA in the original recovery, but sideloading stopped after uploading ~48% every time.
So I opted for the "VolumeUp + Power" mode flashing. Phone was recognized and I started flashing the appropriate TOT file. However at 33% on phone and 28% on the PC, progress stopped. And after a minute or so phone turned off. Currently it has no signs of life at all. Have I completely bricked it now? Is there a way to recover from interrupted "VolumeUp + Power" flashing mode?
EDIT: at first I though maybe the battery died during flashing. But interruption was not abrupt. First the progress slowed down to halt. And then after some time phone turned off.
It seems not all is lost. Have a blinking red light again after leaving it connected to computer for a day. Back to square one, but at least it is alive.
Your motherboard is dead.
And it is not your fault, mine also died while using beta 7.1 and I sent it RMA. They replaced for a new one.
But in my case i had unlocked bootloader, I flashed back 7.0 and it gave no results, still bootloop that's why I sent
Thanks for the info.
After leaving my phone with a clamp on a power button throughout the night (so the red light would flash continuously), I got it booting into "VolumeUp + Power" mode and this time I have successfully flashed the same TOT file via LGUp software. It was still bootlooping after flashing. Now I was able to enter into bootloader and recovery and this time sideloading the same previous file actually works. However it still bootloops.
Anyway, I tried to RMA it and after giving my IMEI to the Google rep, they said that they could not find it in their system after checking US and UK store records. Also tried calling LG warranty, but they do not know of my IMEI either. I got this phone from Swappa, so I left wondering where did the original owner of this phone got it from. He claimed that he got it as a present...

out of curiosity, have you ever tried to flash custom recovery through the bootloader ? If you can, you might also wanna try to make a EFS backup, wipe all partition, then flash custom rom or near-stock rom like this one, just for the sake of testing.

I wanted to flash custom recovery but was unable to do so, because device is still OEM locked. And I am unable to unlock it, because I did not do the confirmation in the Developer Options before device started to bootloop. Is there a way to flash custom recovery without this step in Developer Options?

For now, no way that I can think of. You could try to oem unlock it until it work, just cross your finger I guess?
I have some progress here. Since I was able to sideload various OTA images, I started doing that one by one and seeing if some of them would not bootloop. And after flashing 7.0.0 (NRD91N) from here (https://developers.google.com/android/ota) phone booted successfully and now is working. Will report if I get any problems.
Hi, i just recently bought a used zenfone 2. It has a really old version of lollipop android (2.13 version) and i want to upgrate to 6.0 android. Problem is i can't get into recovery mode. Everytime i download the update phone restarts, but instead of seeing recovery screen i see usb sign. The phone turns off after a while and tries again-but same usb screen. Getting into it manually i get the same usb screen. What to do? All i can guess that the phone was tried to be rooted and failed, as i found SU program.(Phone itself boots up normally as i should!)
I'm still new to these things, so please keep it as simple as possible and ask anything more you need to know.
here are two things if you think BL is already unlocked download latest TWRP and flash that. if you think BL is locked download recovery image for the same version you are currently on and flash via fastboot

Well that's the thing, i can't do both ways, cause holding power+volume up buttons i instantly get a usb screen. If I could enter it i wouldn't have any problems. Bootloader is locked, when i start up my phone the asus splash screen is black, not white.

one thing did you use xFSTK to recover your device recently? what is your model number? send me you device serial number. do not use xFSTK you may brick completely. after boot check with root checker app from app store if you are rooted. as you stated found su binary on device. and revert me back
Long story short, I ended up with a classic bootloop (shows boot animation continuously) from messing around with Magisk modules, so I did a wipe from recovery, still bootloop, so I tried reverting completely to stock with the OEM downloads. I tried flash_all_except_storage.bat, and flash_all.bat, but this time it was a different bootloop. The phone shows the Android One logo, the screen flickers like it's going to the boot animation, but then it just goes back to the Unlocked Bootloader Warning Screen, then the Android One logo, and loops like that. I dumbly thought locking the bootloader, reflashing everything, and starting over like it were a new phone would fix the issue, so I did flash_all_lock.bat, but now I'm just stuck with this weird bootloop and a locked bootloader. Trying to unlock the bootloader with fastboot just gives me "oem unlock is not allowed", so I'm at a loss here.
Does anyone know of anything else I could do, or is this a hard brick?
With a locked bootloader EDL flash probably is your last chance.

I got stuck with a similar problem and that was the only option, to boot into EDL mode you will need to partially dissasemble your device and flash the image via fastboot or via MiFlash (download the latest version as I had problems with an older one). Since that incident I kept the bootloader unlocked just in case something happens.
I had the phone booted into EDL mode and attempted to flash the stock ROM (10.0.3.0) with MiFlash, but it errored out with an ERROR_UNSUPPORTED_TYPE. I tried with the previous version, 10.0.2.0 and it worked for some reason. That fixed it though, so thanks! I've been lightly tinkering with rooting android phones a few years now, but until encountering this issue, I'd never heard of EDL mode. You learn something new every day? ?
I have the same issue with my nephew 's mi a2 lite which has the bootloader locked.
It only shows the android one logo.
I cannot go to recovery mode, but I can go in fastboot.
Changing from "a" to "b" doesn't solve anything and being the bootloader locked is not possible to flash anything from fastboot.
So I've opened the device and I've short circuited the edl pinpoint to be able to flash with MiTool (I've used an old version since more recent ones gave errors when flashing).
I was able to flash both the latest official ROM and the oldest one which I've found ( daisy_global_images_V11.0.14.0.QDLMIXM_10.0 and daisy_global_images_V9.6.4.0.ODLMIFF_8.1 respectively).
In both cases the device still is "frozen" with the android one logo when I've tried to turn it on after the flashing procedures gave me a successful status.
What else can I do?
Must be rusty in my old age, but I dont remember having any of these issues back with my previous android phones... the 11 is my first new one since the 6T though.
Whats my situation:
Phone boots into fastboot, attempts to boot to recovery, or continue, or restart all end back at fastboot. Can issue fastboot commands, but all roads seem to lead back to fastboot.
How I got here:
When I first got my phone, I unlocked the bootloader via fastboot command, but for some reason my phone wouldn't let me set a pin. Be it numeric, alphanumeric, or pattern, it would never let me confirm after putting it in the second time, and consequently I couldn't register a fingerprint or face scan. Reddit suggested that this sometimes happens after bootloader unlock but can be resolved by re locking and unlocking again... ok fair enough, haven't done much yet, whats another factory wipe.
fastboot flashing lock command - finished, boots straight back to bootloader
fastboot flashing unlock command - finished, ok time to try booting through to see if it fixed the problem... stuck in fastboot.
I'm rusty enough to want to stop here and seek guidance before I further brick my phone. I have fastboot access so in theory I should be able to flash an image from here? Any guidance would be appreciated. I'll admit I've fallen off the scene hard (new baby, job etc) and perhaps I should have just left my phone locked... but habits die hard eh?
You can only flash the full rom /images with unlocked bootloader
With locked bl you becomes the messages
Flashing on locked states not allowed
did you flash a patched init_boot.img after your first unlock?

You need to re-unlock the bootloader in the original china ROM!
I can help you if you get stuck on this issue ! pm me! !
I did indeed reunlock the bootloader. I imagine the issue possibly when I was attempting to root by patching a boot img with magisk and flashing that... Although after doing that my phone seemed to operate fine.
Regardless I reflashed the original, and it seemed to still bootloop into fast boot.
I tried relocking the bootloader, going to recovery, etc. After some degree of insanity doing seemingly the same thing I got to stock recovery, and then back to bootloader then back to recovery, then it flashed me writing in Chinese and it booted normally.
Since then I've rebooted my phone with no issue.
Not sure what exactly happened to make it conditionally work/not work... But given the time I wasted on it and the infant I'm having strong second thoughts about bothering with an unlocked bootloader. I'm clearly not in my element anymore as my confidence of which files to flash and commands to do so was very low (hence the post). My initial suspicion was "I have fast boot I can just flash original rom and I'm back to square one at least" but was too "afraid" to proceed and brick my new phone.
To expand on the "why bother with unlocked bootloader", I feel like it's been 3 phones since I truly took advantage of unlocking my bootloader. Perhaps I need to read more about the current state to see if there is a value proposition for me, or if I'm just creating more work (to then root, magisk, TWRP, safetynet, windvine etc)
Same happened to me,
Possible solution:
I used fastboot enhance to flash the payload.bin all over again, after it finished it rebooted into fastbootd automatically, then I falshed the same payload.bin into fastbootd as well then it rebooted into system smoothly.
