Unlocked Pixel XL is completely unresponsive after two spontaneous reboots. Shortly after those, while on Twitter, the phone just blacked out and is now completely unresponsive. Holding the power button does nothing, and plugging it into a charger does not bring up the charging icon or anything for that matter. When calling it the line was ringing, but the phone was completely silent. After swapping SIMs out, this is no longer a symptom. Connecting the phone to my PC shows a "Qualcomm HS-USB QDLoader 9008" device in device manager under COM Ports (COM & LPT).
It sounds as if my phone is bricked. A classic fix would be to just replace it. Unfortunately, I need the phone for the next few days and I don't have access to the vendor who sold it to me. I found this guide to unbrick devices that show up like this. Is it worth following?

I have a stock factory unlocked i747m. It used to connect to the computer via usb no problem but than it had some contact with water and would only connect to charge after that - everything else worked fine. Than I downloaded the new android update, hit install, my phone turned off and it won't come back on. When I press the power button it briefly shows a screen that says 'SAMSUNG' with the words 'Recovery booting...' in blue letters in the top left corner. That screen stays on for 2 seconds and than the phone just shuts itself off.
I can't get into recovery mode, tried everything -- volume up home power .. volume down home power .. volume down power -- nothing works. Before this update it would charge via usb cable but was unrecognized in ODIN and Computer (windows 7 x64).
Is there a way to unbrick it or is the motherboard done for?
Don't suppose theres a better or cheaper way to fix it myself than this http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-iii-jtag-brick-repair/

I hate to see questions like this go unanswered. I'm sure you're in a world of hurt right now and would be willing to try almost anything. My first thought would be to consider pleading with the store for a doa return or 30 day exchange. If that is out of the question then you may need to look into whether a usb jig will work for you. The issue their is that you were having usb/computer recognition problems before so it's impossible to say if that will work either. I have never had to use that JTAG brick service but their website seems convincing enough. Reviews of that service look like the cost all in will be around $100, but I would be sure they will still take it with the water damage. I think I would contact JTAG and fire it to them with hopes of a speedy return. Just my two cents...

Hi All,
I recently tried to fix my older sons xperia zl, The phone would not power on, it did not show any signs of life when plugged in to a computer. Tried all the different button combos and the off button at the back of unit but still nothing.
So I opened it up and checked each component visually, did not notice anything wrong.
I decides to see what would happen if I disconnected the battery and plugged it in to just usb to the computer.
Well it showed up in device manager as a SEMC flash device, and the red notification light came on. Then it started to try to turn on without me pushing the power button, the screen gets to the sony logo and then goes black and starts again.
The next thing I tried was to flash a new rom to it, under Flashtools it automatically goes in to flash mode, found my rom and hit flash and it completed the flash. Disconnected the usb , connected the battery but nothing no power and still nothing in device manager.
Another weird thing that happens is that while the battery is disconnected and i hold the vol+ a blue notification light turns on and the phones goes into fastboot mode.
I initially thought the battery was the problem so I ordered a new one and installed it but the same thing keeps happen, anytime the battery is connected the phones does not react to and buttons, even when the usb charging cable is also connected.
I am wondering if someone has a schematic or know of a capacitor, resistor or fuse that is stopping the phone from recognizing the battery.
Any help would be greatly appreciated.
Basically, the device wont turn on no matter what I do, no matter what key combinations I use. If I plug it into a power outlet, the LG logo comes up, then the tablet shuts down, then the LG logo comes up, rinse and repeat.
If I plug it into a PC, I get the sound of it connecting and disconnecting over and over, but nothing comes up on the display.
I've never had a bricked device that I couldn't unbrick by going into adb or download-mode but I can't even get into download mode. I'm stuck and ran out of ideas.
Any help would be greatly appreciated! Thanks!
EDIT: I got it to show the charging logo. Basically just left it plugged in doing the logo-loop for about 15 minutes until the battery indicator showed up. Very strange. Hopefully once it's charged everything will be fine.
Have you pressed the volume up key + pressed the power button multiple times over and over, I can get mine into download mode only if I use that method.
When I corrupted my tablet, first it would hang on the LG logo screen and never boot into anything, once, then I got the issue of it boot looping only into TWRP only even after installing ROM's, then flashed TWRP in TWRP, and wala, fastboot boot loop only, for the life of me I could not get it to go into download mode, I had almost given up, but alas the last attempt to randomly smash buttons unveiled that holding volume up + clicking power over and over rather quickly rendered it to download mode...
If your getting the LG logo screen its likely that you can recover it.
As for the connecting/disconnecting, its likely that the device your connecting it to cant provide the power being pulled by the device, I have to use a powered USB hub for my Alienware 17 (R2) early 2015 laptop, as it cant handle the power draw of almost any devices, I have had issues even with self powered USB portable hard drives, so I really can feel your pain.
So it has been 2 years since my M8 got hard bricked, however staying home during this quarantine got me thinking if i could try and fix it or not, so 2 years ago
i took my M8 out of my pocket it was not responding and slow so i restarted it and since them all my phone shows is a black screen, when i try to charge it the battery icon doesn't appear still the same black screen, just for a brief second after plugging it to charge the orange light up there flickers and then nothing more, when i connect it to the pc it's recognized as qualcomm hs-usb.
My M8 was with unlocked bootloader, but S-ON, had TWRP installed on it.
Maybe you can replace a new battery, which will give a hope.
Exactly the same issue here, but tried a new battery, no go. Have you managed to find anything since last April ?
When the brown light blinks and doesn't turn on it usually means the battery is too low to turn on the phone to display that its charging, normally it takes a few seconds or minutes depending on your charger, if it does turn on in a few minutes in my experience it means your battery is dead.
Another trick I was told about is holding the power and volume down button for 15secs while plugged in then hold the power button for 10secs.

Any chance you could confirm that when plugged in to the pc it's recognized as qualcomm hs-usb. I got a feeling the bootloader got creamed, i believe it should be showing up as a HTC something...

I tried it briefly with my dead battery phone and it did not appear because it went off right after the boot screen, i
Have you tried to leave it in the charger and see if the blinking brown light turns green indicating full charge, alteast that way you can rule the battery out as the problem.
From the little googling this is the best answer I could find

Thanks for helping, i''ll fiddle some more with it once I find some Schematics.
Have a P3XL that I'm I was going to load a custom image on. But I can't for the life of me get it to recognize having any form of usb data connection.
When I plug it in, it simply starts charging, no usb notification appears on the phone for adjusting the connection, the computer doesn't make a sound, nothing.
With the very same cable I can plug in a P6 and P3 and they will immediately be detected in the device manager.
I've tried messing with all the USB settings on the phone, turning them off, adjust the default use to File Transfer / etc... (note that none of this is from the usb notification, but the actual usb settings under preferences since it's unable to detect it's even attached!)
I'd had a couple issues with the port only charging sometimes so I bought a replacement charging assembly and installed that assuming that would make all my problems go away and while it definitely fixed the cable so it charges every time, it continues to refuse to be recognized as a device.
Does anyone have any ideas what would cause something like this and what might be wrong to cause it to not be recognized AT ALL (to re-iterate, the computer literally can't detect that a device was attached it's not doing anything, both with old and brand new charging port).
(One other quirk, not sure if it's related...The phone never actually stays off. If you power it down, it will power itself back on just a few seconds later. The power button itself isn't stuck and works perfectly for all the normal functions: tapping/holding etc.. And to be clear, it never shuts itself off randomly or anything like that, it's just if you hold the power button and choose "Power Off" it shuts down and then just reboots 2-3 seconds later)
