[Q] Phone won't charge, no LED, USB makes on/off sounds but won't recognize device

Hello! Last night, my phone died while I was out. When I got home, I plugged it into the wall charger and I noticed the LED didn't come on. I left it charging overnight for about 6 hours and tried to turn it on - no luck. I read on another topic that you needed to charge it to ~2% through USB for it to begin charging on the wall if it's "too" dead, so I left it on my laptop for an hour but again with no luck. I did notice that my laptop couldn't recognize a device though, and since my phone was the only thing plugged in, it means my phone was 'on'. I held the power button and the device disconnected, held the power button again, the unknown device reconnected. So my phone is turning on and off, so I wondered it was my screen. I turned it on, but no sounds worked when I messed with the volume button, so I'm going to rule the screen out. Despite being able to turn 'on', I can't get into recovery and it won't truly turn on.
I'm rooted and unlocked, running a version of PA, though I haven't updated it in some months and haven't downloaded anything other than a picture or two to my phone recently, so I don't think I've bricked it or anything.
I've never used ADB or fastboot or anything like that, so if there's a solution through that I'd be happy to try it out. If there's anything I forgot to mention, please tell me!
Thanks in advance for any help I can get.

This has happened to some people. It seems like going completely dead can somehow corrupt something in the firmware in rare cases.
Open Device Manager and plug in your phone, then see what pops up. If you see QHUSB_DLOAD, your phone has bricked, but it may be fixable. Check into the Unbricking Evita thread and see if the guys there can help.
Failing that, get a warranty exchange.

Try different button combinations (hold power, or hboot combination) while the phone is plugged into the wall charger. At least one person I was trying to help, got his phone to power on this way, when nothing else seemed to work.

Sounds like you're phone is in qdl mode. i second trying the unbricking thread.

Bricked WT19i?

Hello!
My sister dropped this SE WT19i phone and after that it stopped working. It doesnt power on, the led's not showing anything while charging nothing! Everything is dead. Only thing that happens is that Qualcomm HS-USB QDLoader 9008 (COM7) shows up in the device manager.
I've googled and it looks like its "hardbricked" is there any way to bring this phone back to life? I tried changing the battery, since the other one gave me 0.0000 volts when cheching it with a multimeter. Now its giving me a steady 3,6 volts but it still doesnt turn on.
I cant seem to connect it with any Flashtool. It's like every software is gone in the phone :/
Help very appreciated! Thanks!

Is my Nexus5 dead or only its battery?

Howdy!
My phone doesn't work anymore, and I try to assess what's going on. I searched before posting, and I decided to post here because I found mixed answers.
Context:
I bought my phone in January 2014. I took extra care of it, it has never fallen on the ground from high, no scratch, nothing. Regarding the battery, I tried as much as possible to charge when it was close to 0%, I wasn't a heavy user of my phone, and I was turning off a lot of things so that the battery would not deplete quickly (Wifi, localisation, Bluetooth, auto-typing, et cetera...).
However, recently (the last month), I was feeling the battery was weak, depleting more quickly than before. I also felt the phone was warmer than usual. Sometimes the phone would turn off suddenly when I was short on battery (under 15%) and using a "heavy" feature (photography with flash, video game).
A week ago, the phone suddenly turned off, never to turn on again. The phone died. I was just typing a message, the phone was charging and the battery was around 60%. I was surprised.
As of today, the phone doesn't turn on. Plugged on a wall outlet or on the USB port of my computer is the same.
I tried many combination of buttons to fastboot, reboot, reset, or whatever, nothing sparked any life in my phone. (I tried holding power key for 30s+, 15s+ ; I tried holding power key + volume up for 15s+ ; power key + volume down ; power key both volume ; in fact whatever combination I could read here on XDA forums, on Reddit, on Google Forums...).
My first insight was: it's just the battery. I can buy one off the internet, and voilà!
However, when I plug the Nexus 5 on my computer via USB, the computer reacts with the sounds when you connect something. Is it just the battery then?
At first, it was saying: "QHS_USB BULK", and the computer was trying to install whatever to make that peripheral work.
When it was done, it read "Qualcomm HS-USB QDLoader 9008 (COM4) has been correctly installed.
Hum, okay.
Still, nothing shows in the peripheral.
I continue to hear the plug in plug out sound when I... plug in and out my phone in the computer, but that's the only thing.
With all that, I can't really tell if all the phone is dead, something grilled inside or I don't know what; or if it's just the battery that is dead and the phone is unreachable and unrecognizable when "there is no battery" in it.
I'm not sure if I shall invest money into buying a new battery.
Do you guys can light my lantern on that matter?
I would greatly appreciate it.
Thanks,
Cheerio!

If I may just address a little bump on this very subject of particular interest to myself :3
Cheerio!

Any insights on this? mine´s doing the same. Doesn´t turn on or go into bootloader, when i connect to charge it red light blinks for like 10 sec and then goes off. Nothing happens after hours of charge.
Did you try replacing the battery as you mention on the post?

Sorry, but have to say this with caps: BLINKING RED NOTIFICATION LED MEANS ITS DEAD BATTERY. Can't be 100% sure, but usually it means that the phone doesn't have enough power to boot up. Mine did this when it drained to the absolute 0%
edit: There can be other problems with power going to phone, but if you are lucky its just the battery.

So i changed the battery. When i plugged it to charge no red lights came on, just the typical white battery with the light bolt appeared for a few seconds, after that it went on with screen off (or at least i thought it did). After 3 h of uninterrupted power charge i went to turn it on. Nothing happened. Can´t turn it on or go into bootloader.
Nothing happens on my pc when i plug it. No sound and nothing on Device manager (no drivers for nexus 5 installed, don´t know if that matters for windows to recognize it as any device even if its not as android device).
Edit: yeah, i got enlightened and literally unplugged the battery and plugged it back in and it worked like charm. I get stuck on the intro animation but i can get into bootloader and recovery just fine. Just gonna install those drivers and flash something. right? Thanks to everyone that read and even more to those who replied!

Yeah, search from youtube how to flash factory image nexus 5. It should make it work. And try to find video with using adb instead of toolkit, adb is way more stable/trustable. (ADB is the android debug bridge, it may look like very hard and confusing but in the end its just typing 1 command and it flashes everything needed) If you need help in flashing the image, just ask!
Try this, it installs only tools needed for adb (also drivers) http://forum.xda-developers.com/android/software/tool-platform-tools-adb-fasbootdrivers-t3061441
Edit: This should work https://www.youtube.com/watch?v=5ka5dnPghzI

N5 dead after logicboard "swapout"

Hello,
so here's what happened: I got a fully working N5 with 16GB and a 32GB version which has a broken screen.
Today I tried to replace the logicboard of the 16GB version with the one built into the 32GB one.
The phone didn't start up, neither it reacted to getting plugged into a charger (usb pc & wallcharger both didn't do anything).
I came to the conclusion that the logicboard of my 32GB N5 must be broken aswell, so I put the original 16GB logicboard back in.
The phone booted up normally when all of the sudden it just turned itself off after 5 minutes.
Since then it doesn't start up anymore. Having it plugged in into the charger doesn't do anything either.
I've already tried to get it into bootloader etc but nothing works.
The phone simply doesn't turn on anymore.
When I had it plugged in on my pc I once got a NON-flashing red light, but it seems like I can't reproduce this.
Any ideas?
It would be nice if there is anybody who could help me with my problem.

Swapping the logic board shouldn't prevent the v phone from booting unless something happened during the swap process.
When connect to a windows computer, do you see anything about qhusb load in device manager?

After holding the powerbutton + vol up + vol down "QHSUSB_BULK" popped up

That type of "device" is an indication of a hard brick. Disconnect and reconnect without touching anything on the phone. If you see something similar with 9008 in the device name, it could be a soft brick.

After installing a driver it showed up as Qualcomm HS-USB QDLoader 9008. Followed a tutorial using "BoardDiag" to unbrick the device. unfortunately the device remains "dead", no sign of life
:crying:

After having it appear as a "...9008" in your computer, disconnect it from the computer and leave it alone for about 30 minutes. After 30 minutes, try and boot to the bootloader.

No response or any indication from my Z5 after a black screen

Here is what happened. I was playing Crashlands when I noticed that my battery is at 3%. So ran to get my Quick charger to get some power fast. After connecting it, I tried to unlock the screen and it went black after a second. So I was thinking that it just shutdown because of low battery. I pressed the power button and noting happens, just the red light showing it was charging. Then I tried soft restart (power + volume up) and it vibrated 3 time and probably shutdown. From that point noting I did started the phone. Even using the off button next to the Sim tray. When I connected it to my PC is ether recognized as Unknown USB device or SOMC Flash Device. I should probably mention that the phone was hot from the game before connected it the charger.
I had the phone for one year and a bit. It is not rooted and i just recently installed the lattes update from Sony. Currently I have it put to charge, at least it looks like it is charging (gets little hot).
Is my phone bricked or something else? What should I do?

I have same problem like this.
Hope someone can help us.
QHSUSB_DLOAD device will show when Connected PC.You can use Flashtool to install the driver.
Unknown divices : because you should complete shut down the power (Disconnect the buttery ).
flash tool will find the phone ,but can't flash.
seems Z1 have a way that find the test point to recovery boot file.hope z5 have the same way.
Sorry for my Poooor English ,hope you can understand what i say and have someone Help US.
