Stock Phone Stuck in Bootloop - Google Pixel 4 XL Questions & Answers

Hello everyone!
I have a Pixel 4XL, bought it when the phone was released. Phone is fully stock, not rooted or flashed with any custom ROM, the bootloader is also not unlocked.
I pulled my phone out of my pocket yesterday and it was on the google logo loading screen that you usually see when you boot up the phone. I assumed that it restarted itself because it was too hot (it felt sort of hot to the touch). But the phone never rebooted itself, it was stuck in the booting screen forever.
I then tried various ways to restart the phone, through recovery mode etc. However, I couldn't get my phone to boot back up. I have yet to try factory resetting the phone as I do have some files in the phone I really would like to keep. Is there any other way to resolve this without a full device data wipe/reset?
Thank a lot in advance!!

You can try rescue mode and using the tool Google has online. https://pixelrepair.withgoogle.com/
Depending on the issue and what the tool has to do it may factory reset it.

Thank you! I will give it a shot!

I was hoping that sideloading the May update OTA would revive my phone but it didn't happen so I had to cut my losses and factory reset the phone. I really hope this never happens again...
As my phone was stock and the software never altered, what would cause a bootloop like mine?

A friend had the same issue. It appeared that his power button actually got stuck internally so he tried to press it from lets say different angles. It worked, he saved all his data and was fine.

[Q] Stuck on boot animation after flashing Stock ROM

Alright, here's the story. I needed to unlock my phone, so I looked up a few guides. I found one that I like and was checking to see if the ROM I had installed would allow me to enter in my unlock code after I got it, unfortunately it wouldn't. So I decided to flash the stock ROM for my phone. Odin did it's job, and everything seemed to go alright, but after Odin finished up, the phone still remained in the boot screen. I let it sit for a while, and it continued on for about half an hour. I restarted it, went to go do some things. I came back hoping that my problem would be solved, but nope, still a looping boot animation. Has anyone else had this problem, or have some idea on how I might work around this?

Enter recovery and wipe data

[B]thats the hardest brick man[/B]
happened to me while doing something stupid to my kernel... believe me it is impossible to fix.
i took it to my ISP they said its liquid damage but it wasnt i knew... they said BER(beyond economic repair)
so i took it to samsung and collected it after 10-15 days. from the looks of things they changed my motherboard.
you can return it even if warranty is void(they cannot tell if its void or not)
mine only blinked when i tried recovery,download or charge and showed logo when i turn on only.
Hi There,
You will need to enter the Recovery Mode and Have a Factory Reset and Wipe Dalvik cache. If the device doesnt enter recovery you can force it to do so using JIGG or Heidmall. After wiping if still no progress. You should check whether you have flashed the correct stock rom according to your Country.

Moto G(2014) stuck in boot screen

Guys I was copying movie to my phone using usb cable.
I was copying it to my phone memory as i have not yet put a memory card.
While copying it got stuck at 90%. Then I canceled the copying after which my phone restarted.
When it booted it was very sluggish and i wasn't able go to the menu. So I turn off the phone and switched it on again. This time also it was sluggish so I again turned it off and when I turned on it got stuck at the Motorola logo powered by Android screen.
It is not going any further I have tried many times. I even went to fast boot and tried the recovery and factory option. But nothing happened. It will come back to the boot screen again.
BTW guys my phone bootloader isn't unlocked and it is not rooted.
So the phone is in very much stock. My phone is not yet 1 month old. I have never faced this kind of situation in past.
I have like 500mb of pics in the phone memory which I will like to get back.
Is there any way to fix to phone without voiding the warranty and get the pics and video back.
Any help will be very much appreciated..

I think you could only try to "fastboot boot recovery.img" with a custom recovery out there ( like twrp from adrianom ), but probably it won't work with a locked bootloader

And unlocking the bootloader will void the warranty.
So it is of no use
Guys I gave my phone to service center. The at the service center said the reason behind this boot loot might be over night charging, Phone falling from hand. I was confused like how can hardware problem lead to software problem. How is charging related to OS corrupting.
He said that it can also happen but installing corrupt software..
It didn't make any sense.
Can you guys can put some light in the matter...

July OTA Update Bricked my Phone -- AT&T refusing to replace. Help!

Completely untouched phone from AT&T. Have never rooted or modded this phone in any way.
The update that came out this month was sending my phone into random boot loops. Would have to take the battery out and after a few tries it would stay on for a while then at some point in the day randomly go back to the boot loop.
I backed everything up through Kies then went into the recovery menu and attempted a factory reset. This sent the phone into a permanent boot loop -- would never turn on or off. Sammy logo flashes and it would reboot. Only way to get it to stop is to take the battery out.
Attempted to go back to 4.4 through Odin since those where the only firmware files I was able to find. Updated failed. Now, when I turn it on and I just get "Firmware upgrade encountered an issue. Please select recovery mode in kies and try again."
Kies will not recognize phone. Cannot update firmare from internal storage because I can't even get into recovery menu -- it just goes right back to the same screen.
Called AT&T and the rep told me he would replace the phone through warranty even though I was past my warranty date. He told me this update has messed up a lot of phones and this is not the first he's of it. Then his manager gets on to approve the warranty replacement and she refuses to honor his promise -- tells me they won't do it, I'm SOL, and I can use my upgrade. Maddening!
Please help -- I need a working phone!

Most attempts to downgrade only flash the kernel so here is the OF2 kernel which should get your phone to boot again. Flash with Odin:
G900A_OF2_Stock_Kernel
Once your phone boots place the G900A_OC4_tF2_OTA.zip onto your extsd card and flash as update from stock recovery. That should get you back to 100% factory stock. Do a factory reset after flashing and if it still does not work I suspect a hardware problem.

Thank you for the reply!!
Kernal flash worked and I was super excited to get back to recovery menu -- way more progress than I've had up until now!
Unfortunately when it went to reset after installing the update from external storage, it went straight back into the Sammy logo boot loop
Is there physical damage on the phone, thus why att didn't do the warranty?

Take it to Best Buy or an ATT Store and have them reflash it before you toss it away. Good luck

No idea what just happened. I've been messing around throwing the kernel you recommended at it as well as the stock partitions. Kept getting back to boot loop but at one point it stuck out, said it was upgrading, optimizing apps, and now it's running. So weird.
I'm way too scared to do the factory reset at this point, though.
Thank you again for your help, I really appreciate it!
Edit: Unplugged the USB cable and it immediately shut off and went back into boot loop. Wow.
this sounds like a hardware problem.. i sent my phone to Samsung and they actually repaired it, it was the pba board, i had the same problem.. i flashed everything it needed to recover from a bootloop. and sometimes it would become non responsive. go to best buy and see what they tell you.
Sent from my UNROOTED SAMSUNG-SM-G900A on OF2
Update:
Thanks to everyone for their replies. I was able to get the phone to boot thanks to everyone's help. Did this by flashing kernel then partitions which would allow the phone to boot.
I finally figured out that the phone would only boot if plugged directly into a power source. As soon as I disconnected the power cable, it would send it right back into the boot loop. I ran some battery "repair" and "calibration" tools but these did not fix the issue. Whenever I would run a battery drain tool, the stress on the battery would cause the phone to shut down.
All of this led me to believe it was an issue with the battery. I held my wife's S4 battery to the contacts on the S5, and it works just fine, even disconnected, and even with the stress test on the battery.
SO -- I'm going to buy a new battery and see if this fixes my problems. I think I just had the perfect storm of battery issues coupled with firmware problems.
I'm pretty sure I know what caused the battery to go haywire. I work in a max security prison and have to leave my phone in the car all day. Outside temperatures regularly hit 105F+ during the summer, so who knows how hot it's getting in the car. Obviously I always leave the phone turned off, but I suspect the high temperatures caused the damage.
Going to try to find a new battery today. Will keep everyone posted! Thank you again for all of the replies.
I had the same issue and would just like to thank you for the files! They helped me unbrick my phone! Much appreciated.

Soft Brick

Hello,
Today, while I was using my phone, it restarted itself and has been stuck at a boot loop almost entirely since then. It has successfully booted up 2-3 times but will usually restart itself within 30-45 seconds of booting and then will be stuck in a boot loop again. When it has started up its usually after it has been bootlooping for a while. I'm rooted and using xTreme Rom v2.0. I have had occasional random reboots here and there before but the phone always booted right up again without any issues. I haven't done anything with root/recovery since early September.
I've tried doing a factory hard reset without any luck. My phone booted up after I tried the hard reset and it was like the reset didn't happen. I can't boot into TWRP. I can boot into download mode and I tried to reset using kdz. It got to 100% but the the phone restarts and is back in the boot loop (then the lg flash tool gets an error and force quits). I've tried removing my sd and sim cards, I've tried swapping to a different battery, I've tried leaving the battyer out and letting the phone cool down. Nothing is working. I have noticed that when the phone is going to boot up correctly the full LG animation plays. When the phone is going to boot loop I only get a static LG Powered by android image.
Any suggestions?
Since I tried to rest using kdz I can't get past the boot loop...Device also isn't recognized when using adb
edit: It booted up once this morning and went to the initial set up screen, like the kdz worked. But about 30 seconds-a minute later the phone locked up, rebooted and has been stuck in a boot loop since.
That's weird..
So the KDZ goes through all the way successfully.
Phone does the update all apps etc.. and it still boot loops after a while?
Which ROM version are you updating it back to?
My phone just did the exact same thing. I'm also on the Extreme Rom. Everything you described is my experience too. When I use the LG tool it goes all the way through and reboots the phone but just keeps bootlooping. Did you find a fix? I've tried everything i can think of. Probably going to take it in tomorrow and get warranty on it.

I used the following method:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Download the correct KDZ file to flash back to and follow the rest of the instructions. You can also look at this video tutorial. https://www.youtube.com/watch?v=zXO2SHqBiNk
The one you'll want to try is "Normal Flash"
"CSE Flash" is a full wipe that deletes all data.
Mine was weird where it told me my phone disconnected, but the progress bar was still continuing. If that happens to you, don't hit cancel, let the progress bar finish to 100%

Blu R1 HD Soft Brick

I have a Blu R1 HD that I have been on again off again fiddling with for a few months that is soft bricked. It will turn on but it will hang on the second "Bold like us" splash screen after the animation ends. It had no recovery installed to it prior to the bricking, I have attempted flashing a stock rom to it with SPFT but It gets interrupted less then 3 seconds in. From my reading It seems like I have the 6.6 preloader that stopped spft from working.
Is there anything that could be done with this to get it working once again?

Depends on few things.
Do you know what was last thing done before this brick?
Have you tried holding volume up when powering on, to enter recovery(stock, i know you mentioned no custom recovery installed)?
It goes to and past the animation , so i don't think it is a secure boot type of failure. But maybe a bad data problem. See above statement about recovery.

I have gone into the stock recovery menu, And i have attempted factory data reset, clearing the cache, and a root integrity check. The integrity check says one item fails the check and that is "/system/lib/libLLVM.so"
The last thing that I recall happening is that I had a pop up saying that an app had stopped working, But it reappeared immediately after closing it again several times. I thought rebooting it would stop whatever was happening, but it never came back to the OS.
The device has a small crack on the bottom right hand side of the screen that happened when it fell from my pocket on top of a ladder. A family member who also works with electronics as a hobby thinks that may have something to do with it but the phone worked for weeks after the break happened.

I do not know if there will be any way forward with this.
As you are not bootloader unlocked, sp flash refuses to connect, and only thing that can be done on stock is "factory reset" did not help, you might be done , other that see if can send to Blu.

Sending to blu isnt an option. Out of waranty period, And I also opened it to make sure there was nothing obviously physically wrong.
I also tried using the dirty cow tool, But i cant seem to see the device in ADB. Fast boot however, can see it.
Update over ADB/SD in the stock recovery wouldn't lead me anywhere would they?
