Bricked phone data recovery?

Hey guys, recently my phone updated to Android Nougat 7.0. This was a Google update, no root, no custom roms, nothing. Straight out of the box Nexus 5X. Everything worked fine, until the phone froze.
First, a little backstory. I was watching a Snapchat story and one of the Facebook Messenger chat heads was in the way, so I swiped the chat head away so I could watch the story. The phone froze, so I just figured that Snapchat and Facebook Messenger weren't going to play nice together. I held down the power button until the device turned off, then I tried to restart it. I got as far as the "Google Splash" screen for about 15 seconds or so and then the phone went to black. I've tried fastbooting into recovery mode, and the phone went black every time. I put it on my charger and it showed the image of a battery with a lightning bolt and then cut to black. Pushing the power button had no effect. The phone would no longer even attempt to boot. Occasionally, I can get the phone to fastboot, or try turning on, but then it just dies again. I'm assuming the is a soft brick?
Now for the good part. I called Google and am getting a warranty replacement, but due to poor judgement/paranoia, I haven't backed up any of my pictures to the cloud. I've tried connecting the phone to my computer, but my computer still can't read the device. I keep getting a "device descriptor request failed" error in my computer's device manager. Is there any way to get my pictures and other files off of this phone? I'd like to avoid flashing anything to the phone, because Google is holding a charge on my account for the replacement. If it fails warranty inspection or whatever it is they do, I'd rather not be out $500.
Thanks for any help!

Can you get into fast boot long enough to flash all partitions other then user data?
If you have not tried I would download latest factory image from google.
Edit flashall script by removing -w in there. This will skip the data partition and load all others.
It's worth a shot.
Side note: I personally love cloud backups. I can just log into any other phone now and all my data is back within in your. Photos, apps etc. It is pretty awesome not to have to worry.
If you are not comfortable with this method then you need to do manual backups often.
Update: If your bootloader is locked you are likely screwed from getting anything back. Very first thing I did to my phone was unlock bootloader even if you are not going to root. This does not void your warranty on a Nexus.

Adb pull those files. I know it'll take a while because of subdirectories, but it seems to be the easiest option if your computer recognizes the phone.

I haven't touched anything on the phone as far as software is concerned, I guess I should consider this a lesson learned then? The phone doesn't stay on for very long in fastboot. However, today I've been getting the red "low battery" LED notification. I'll charge it up and see what I can do, maybe that'll buy me enough time.
Admittedly, I don't know very much about flashing phones, rooting, unlocking, etc. I've loaded/installed a custom ROM onto my old Nexus 5 and reverted it back to standard Android, but that's about all I've done.

My computer does not recognize the phone. I keep getting a "device descriptor request failed" error. I don't mind how long it will take, I have a lot of vacation pictures and pictures of my new home on there that I'd rather not lose.

If you can't keep it on long enough then it's likely just a lesson learned. Maybe it's some kind of hardware failure. Try the charge. There is an LG recovery option still but that would wipe your data anyway so it's probably pointless.
I would really recommend just unlocking your bootloader with next phone. So you have some options if something like this happens. This wipes your data so best to do as first thing.
Cloud backup is also recommended. You can use other services if you don't want to trust google. Even apps like Mega can do auto backup of Camera folder. Im sure dropbox and others can do the same. I prefer Google Photos.

Ill have to toy with it and see what I can come up with. Maybe write Google a little note when I return it and see if they can do anything for me. I think it's something software related. It seems like others are having the same issues I'm having. The phone fails before fully booting up.
The phone's seen its fair share of dust, but I've kept pretty good care of it. Always in a decent case, screen protector, etc.
I'll be unlocking my bootloader as soon as I get my warranty replacement. As well as syncing what I can find on my computer. I'd rather not do this again.

Stuck on Google logo, then screen turns off

Hi dear,
My phones was working normally until it freezes and reboot. The problem is that it got stuck on Google logo and then the screen turns off. I have access to Bootloader but not to twrp.
I know how to flash, root, unlock and stuff. So I tried a lot of options starting with wiping cache & dalvick using fastboot and finishing with Locking the bootloader then unlocking it then reinstall stock android / kernel
The problem persist, the phone can't boot, it stucks on Google logo for 5 10sec then the screen turns black
Any suggestions guys ?
Thanks

Any help ?

I just had the same issue with my phone today and my phone is all stock. Did you ever figure out how to fix it?

There is 2 temporary fixes that might help you boot your phone so you can backup your data. Mine died.

Do what did you do? Were you able to boot again?

I had the same issue after sustaining water damage due to dropping it in the bathtub.
What I've learned is that the phone will exert this behavior if there is a problem with the power from the Battery. (You should be able to reproduce this with a working phone by disconnecting the battery and try to boot it just from USB power).
I managed to resolve the Problem by cleaning the Battery connector from the corrosion that had formed from the water.
Alternative solutions are to either replace the mainboard or the battery. If you had water damage, make sure the battery connector is free from any residue and clean it in 90% Alcohol. Do the same with the whole board. If the issue persists I recommend replacing the mainboard first.

Screen won't turn on 10-20% of the time when I try to wake the phone

So I've been seeing a lot of talk about the 8.1 finger print scanner delay, but to my knowledge, this is something else. Anywhere from 10-20% of the time when I go to wake my phone, whether by pressing the power button, or using the fingerprint scanner, the screen remains black. The phone will vibrate like it successfully read my fingerprint, but the display just won't come on. I have to then wait anywhere from a couple seconds to a full minute before it will come on. It's almost like the phone is in doze mode and just doesn't want to wake up. Has anyone had this problem, or know of a possible cause? It's driving me a little nutty. Definitely is something that has popped up since updating to 8.1.

Is your phone stock with a locked bootloader? Have you tried wiping the cache partition from Recovery?
Edit: Possibly related LINK

It could be the 8.1 proximity sensor issue under discussion here.

Funny you bring that up, I just bought the phone and went straight to 8.1 . It's happened twice. I thought the phone powered off. I'm unlocked and rooted. I can't pinpoint the when and how but has happened and will pay closer attention.

OMG thank you for linking this! I was going crazy trying to figure out whether it was something I'd done, or something related to the 8.1 update. My phone is rooted, and I'll have a go at removing magisk and seeing if that helps. Again, thank you!

Exactly what happened to me. I was so confused the first time it happened.

I'm not so sure.... maybe a root app? The long thread I linked to has several suspect root apps, but I haven't had a single reboot and have been rooted on both 8.0 & 8.1.

So it happened twice this morning, both while connected to pc and wall charger when left alone for awhile. Maybe something with deep sleep while charging? Not sure.

Weird bug discovered on OnePlus 5T

Hello everybody,
Yesterday I was on my phone and when I went home using the navigation gesture the phone all of a sudden rebooted, and I thought "Okay, it's just a one time error". When the cellphone booted again it showed the logo and then black screen and a WhiteLED on, it seemed bricked, so I reset the whole phone and it was alive again. However, once again today the same thing happened, no root, no mods, all stock. Has this happened to anybody else ? Do you guys think it's a hardware matter or just software ?
P.S: Happened when I was on Open Beta 10 and this time on OOS 5.1.3. Can't boot into the system nor Recovery, fastboot is fine.
*Update: Phone is now completely dead, won't even turn on
Thanks.

Me too, I remember having an LG G4 back in the day that wouldn't pass 6 months without having to change the mobo, it might be a similar case.

Screen won't stay on

I've recently purchased a used Moto G5 (3gb ram version) from eBay. It's been working fine for a couple of weeks but has suddenly developed a fault, the screen will not stay on. It just constantly goes black / blank. When it boots the Moto logo is shown for about a second and then it goes off and will not come back on until I pull and replace the battery.
I know the phone is still functioning as i can hear it sat waiting at the encryption "enter PIN" prompt on boot up, it makes a click sound when briefly pressing the power button.
The only time I can get the screen to stay on is by booting to fastboot. However as soon as I try to boot system or recovery the screen goes off.
Has anyone else had this issue and is there any way to fix it?

Why don't you try a flash,as if any corrupted partition is there for screen it can get fixed, you can use Lenovo Moto smart assistant app to flash.

It's this an Android app? If so I've no way of using it as the screen doesn't work when the OS boots...

It is a pc application which is use to flash the firmware on your device, it will guide you how to flash the firmware.

OK thank you. Strangely enough after a full night on charge the phone is working perfectly fine this morning! However I think i'll do that firmware flash anyway just in case. Also wonder if I've got a faulty battery...

You can try a flash, but I don't think there is a battery fault, if there any, bootloader also didn't show up, so there are possible changes of corrupt firmware in you device. And did you replace the original screen with other 3rd party screen. As that is also a reason, someone was having similar issue like you but, he has got the problem after screen replacement.so if you have done a screen replacement then that can be a problem.

No it has the original screen. Bought the phone second hand though so it's fairly scratched (but not cracked).
