Nexus 5X stuck at Google Screen. Won't boot stock recovery.

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!

Nexus 5X mixed boot loop & hard brick after replacing screen

tl;dr summary:
- Replaced screen, worked for 1 week
- Randomly switches between hard-brick no response, and soft-brick boot loop
- Boot loops on loading TWRP as well as OS
- Running latest 7.0.0 NBD90W
- Phone is H790 variant
- Flashed Android 7 in the bootloader, not through OTA. This was as soon as Nougat came out, and it worked great for weeks.
- Bootloader unlocked (for temp-booting twrp only, "fastboot boot twrp.img" otherwise kept stock)
- Phone NEVER rooted
- No charging indicator when plugged in
- Battery bent during previous removal, maybe causing issues a week later?
Replaced screen with genuine LG front frame assembly after a running accident cracked my screen/digitizer. Phone worked fine for about a week, then randomly shut off and went into a boot loop.
Now it randomly switches between a boot loop and a hard brick. When it's acting like a hard brick, sometimes it goes back into boot loop temporarily if I disconnect and reconnect the battery. It eventually returns to hard brick.
Hard brick mode:
-- Doesn't respond to any power button presses. Does not indicate charging when plugged in. Entirely unresponsive.
Soft brick mode:
-- Normal boot: normally gets to Google logo and restarts. Rarely makes it to the flashing dot animation. Twice has booted into Android, past the lock screen, and works perfectly for ~10-15 seconds before rebooting.
-- Boot into bootloader: On occasion will reboot itself from bootloader, but rare. Usually works correctly including all adb commands.
-- Boot into stock recovery: Same as bootloader, usually works, sometimes reboots.
-- Boot into TWRP 3.0.2-2 bullhead: boots for a few seconds and then locks up. Has never made it through decryption - will either a) freeze and reboot right after I draw my pattern, throwing an error that it could not mount storage right before restarting or b) freeze and reboot anyway if I take too long before drawing my pattern. It seems to be more time-based than a function of anything I do.
Things I've tried:
Since my bootloader is unlocked, I've re-flashed these partitions with no fix:
bootloader.img
boot.img
recovery.img (stock)
radio.img
vendor.img
I've cleared cache through stock recovery, can't remember if I tried flashing cache.img
I have yet to flash system.img or userdata.img as I have a few files I'm trying to recover... The fact that I can't boot into TWRP, and the sporadic hard-brick behavior, doesn't give me enough confidence that wiping my data will help.
Phone tends to live in hard-brick mode unless I disconnect and reconnect the battery, then it sometimes goes into soft-brick boot loop for a while before once again hard-bricking itself. When hard bricked, no charging indicator appears when plugged in. When soft-bricked and turned off, will sometimes display the battery status after short-tapping the power button. No change when plugged in except only once it displayed the battery with lightning bolt icon for about 2 minutes, before returning to the icon without the lightning bolt.
My best guess is that I damaged the battery during removal.
- The adhesive was really strong, and while I didn't puncture the case, I did bend it somewhere between 30-45 degrees in the process. If I damaged the Li-Po foil, would that make sense for the phone to work, only to go belly-up a week later? I ordered an OEM LG battery for $13 because it's worth a shot at that price point. Arriving next week.
- The reboots sound in-line with it crashing when it tries to draw too much power? Bootloader and stock recovery usually run okay and I assume have a low power draw. The OS and TWRP probably draw more power and that's where it fails? The reboots seem to be more time-dependent than depending on anything in particular that I do, such as rebooting before OR after drawing my pattern on TWRP. And that it sometimes boots into full Android for a few seconds implies to me that the OS is working on at least some level.
Does anyone have any better ideas for when the new battery inevitably doesn't fix it, or things to try in the meantime? Could the common Nexus 5X boot loop under Nougat be causing issues booting into TWRP too? It feels hardware-related to me. I took it all apart and looked for loose/oxidized/bent contacts on all the connections but couldn't spot anything.
My Pixel isn't arriving until Nov 23-25, and to make matters worse I switched to Google Fi 3 days ago and I have no compatible phones to use in the meantime. Oops, lesson learned.

5X HW brick? No loop

Wanted to seek some clarity on whether my phone is HW bricked. Here're the conditions:
Rooted/Unlocked Bootloader/Custom ROM/Stock Kernel
Randomly found the phone not responding last night, no software updates or heavy usage that day.
Have to long press power to get to turn on. Typical bootloader unlocked warning message then Google screen, then phone turns off. No screen content when charging (battery indicator or booting).
I can get to fastboot with power/vol down and interact with from Nexus Toolkit but attempting to boot to anything including TWRP just produces the same sequence: boot warning, google logo then complete shutdown. Tried booting recovery, wiping, etc from toolkit, nothing.
Occasionally it'll loop once or twice but most of the time it just shuts right off.
Phone is in the freezer now, will try heating solder later. Am I looking at a new phone here? Anything else I can try before heading to the store?

Same issue
Did the freezer trick work?
I have the same issue.
Nexus 5X
Rooted/Unlocked/TWRP/Stock ROM
Randomly turned off, Long press to get back on. Turns off during boot. Managed to access Recovery the first time but havent been able to since, just shuts off.
Google chat thinks it hardware issue.. still under warranty, but would be nice to back up the userdata from it some how...

Surprisingly enough the freezer trick allowed the device to boot into recovery.. unfortunately it wasn't long enough to recover any data and now the phone won't turn on at all :/

Pixel 3XL - constant bootloop

So I updated to Android 11 on Tuesday, and all seemed fine. Last night my phone was trying to install an app, and seemed to freeze.
After a few minutes, I forced it to shut-down (power + vol down) and it started to reboot. It got to the G logo with the small bottom bar animation for a number of minutes and eventually kicked back into Recovery mode.
I decided to try rebooting, and it started to reboot, got to the Google logo (the full word, not the "G"), and then kicked back into rebooting.
The phone now constantly reboots and even if I get into fastboot mode, it only stays in fastboot until I hit a key (vol up/down or power) and it then reboots into constant bootloops described above.
If I don't push a button on fastboot mode, it will just start booting anyways after about 3-5 seconds.
Does anybody know of what I could do? Not sure if replacing the battery would help (e.g. a power issue) or if it may be a corruption of the flash memory and that the system and underlying partitions are corrupt leading to nothing I could do to repair the phone.
I have really enjoyed this phone, but I am afraid that this phone is all-but-dead and unusable.
Any assistance is greatly appreciated.
Cheers,
B.D.

You can try flashing the stock rom from recovery or from fastboot.

Had something similar on an og Pixel... Turned out to be a broken power switch.

I had a weird issue last week. Phone would freeze after a couple of minutes and would reboot. It would also boot loop while connected for charging (wireless and corded.). The battery would not charge. I would shut down the phone and when I plugged in the charger, it would boot loop. The battery finally discharged to 0% and shut off. I plugged the charger in and it remained off. I let it charge to 100% and it's been working for the past week without issue. I'm not sure what happened.
I would suggest letting the battery drain to 0% and go from there. HTH

I updated my 3XL to Android 11 two days ago and since then I have caught it rebooting at seemingly random times, though only when it is on the wireless charger. I guess it's back to Android 10 for now. Hopefully reverting a Pixel is as easy as it was on the Nexus. Thanks Google.

Are you familiar with how to use commands in platform-tools to flash stock images? How did you upgrade? OTA? Are you rooted? Is it unlocked or Verizon variant? If unlocked, do you know how to unlock the bootloader?

I am proficient in using the bootloader. Phone has been bootloader unlocked since day one.
I upgraded to Android 11 with ota and all was good for a day (rooted with Magisk canary). Then the phone started acting up, first not booting system and then bootlooping.
I can get into the bootloader (fastboot) but only for maximum 3-5 seconds before the phone reboots, or if I hit any button (vol up/down) the phone reboots. Also, if connected to my computer the USB does not recognize fastboot anymore (before it reboots anyways)
I think it's dead, Jim.

Stuck in too-low-power-to-boot state (bricked?)

Hello!
After recently getting my hands on an old Samsung A50, I thought I might as well reflash and do some stuff with it.
After installing Orangefox and Lineage, everything worked fine until the phone eventually ran out of power.
I plugged it in and let it charge for a bit, but it was just constantly showing the gray circle with a charging/power icon in it, but no battery indicator.
This usually means that the phone is completely empty and has to charge a bit before booting.
After letting it sit for a long while and nothing changing, I got a bit worried.
At this point, unplugging the phone does not change anything - it will continue showing the indicator even while unplugged.
Holding power and volume down (or power + both volume) briefly blacks out the screen, but it simply comes back to the indicator a few seconds later.
All of this happened a few days ago - I eventually got it to boot again through some key combination while the screen blacked out, sending me to orangefox or download mode (i dont remember),
from which I was then able to boot into lineage again. In lineage, everything worked fine again, including the battery indicator which showed that the phone was full, and the battery seemed to work completely fine.
After that, I turned from lineage to Fresh, which also ran fine until Fresh wanted to install an update which sent me to TWRP. Not sure what to do, i just booted back into System which worked fine, but the Fresh update hadn't succeeded.
I attempted to update again and this time shut down from TWRP - big mistake. Now i am once again stuck in the low-power indicator.
I believe that last time i escaped by booting into orangefox - but i think fresh replaced orangefox with twrp?
Anyway, i tried holding different button combinations while the screen is briefly blacked out but nothing is happening (also tried getting into download by plugging into pc, holding power+volumedown, then holding volume up+down while screen is black).
I also let the battery empty itself until it went black by itself and then tried again, but no success.
I'm now again unsure what to do. How do i unbrick this to boot into the OS again? How do i prevent this from happening again?
Thank you all.

Same issue with my Redmi 9, it seems a battery issue idk if i had rekt mine after flashing a latest CN rom then after not being satisfied tried to flash thru recovery to its stock rom and it went bootloop. Fixed it by flashing with SP flashtool and some bypass stuff, but damage has been done with my batt. Maxing out the volume when I try to play something video or music would trigger a reboot to my phone.
