Nexus 6p boots into fastboot, not detected by pc - Nexus 6P Q&A, Help & Troubleshooting

The other day I was trying to flash my 6p back to stock so I can sell it, and I was flashing everything through cmd, until all of a sudden cmd stopped working towards the end for some reason. Now my phone only boots into fastboot mode and is NOT being detected by my pc. When it's plugged in, the fastboot menu says to connect the data cable. I've tried restarting my computer and reinstalling the drivers, but nothing seems to work. When I go into cmd and type adb devices, nothing shows up when it's plugged in, and device manager doesn't show any changes whether it's plugged in or not.
I've called local cellphone repair shops, but apparently if it's not Samsung or iPhone they can't help
Btw I've searched the forums and haven't found a solution to this problem.

Won't charge/power on

Hi,
I own an HTC Panache, never rooted it or anything. Yesterday I factory reset my phone, battery must have died while trying to sync all my apps. Now the phone won't turn on or charge (no indicator light for charging). I tried to load into recovery, doesn't work either. When I plug it into my computer it get's recognized in device manager as "other device" even though I believe I have the drivers installed, and it won't try to mount the sd-card. Finally "adb devices" will return nothing in cmd.
Do you think it's a dead battery problem, and could I recover from this?
Thanks,
Corey

I just wanted to add that my computer is recognizing the device as "QHSUSB_DLOAD"
I found this link that makes it possible to undo this for the HTC Sensation, has anyone tried this on a panache/mytouch4g
http://forum.xda-developers.com/showthread.php?t=1522351
what do u mean by "adb devices" will not return anything?
just so its clearer for others....
u didnt root but installed adb drivers properly? (or just opened cmd & typed adb devices?)
here is a link you can try to make sure u have adb installed correctly & try to downgrade to stock with temp root...or just might as well go all the way

[Q] I'm SO LOST PLEASE HELP!

I own an LG G2, i recently got this phone yesterday from a person on craiglist. Don't worry i didn't pay him i gave him my older phone i dont use anymore. SO This phone is practically stuck in Firmware Update (As i read that post) , i spent about a day and half figuring it out and what happens is that.
I CAN get into recovery its TWRP v2.7.0.0 by Turning off the phone first and then Holding Vol UP, Power, Vol Down at the same time until the LG Logo comes up and then i am still holding them down, and it says Recovery Mode please wait and bam TWRP.
But heres the problem i can't mount my OTG and i can't ADB Sideload. So what do i do from here?? this guy rooted this phone and soft bricked it i think? and he wiped the phone but i also did when i had the chance and wiped it completly via recovery.
The only way i got into "Download Mode" / "Firmware Update" was to take the back cover off and unscrew a few screws on the side and unclip the battery for a few seconds and then plugged it back in and then I held the VOl UP button and plugged my USB into the phone and the other end is in my PC. My phone says "Download Mode please wait" and then prompted with the Firmware Update screen. BUT my pc doesnt detect the phone whatso ever and i've already installed drivers and etc from this forum ( http://forum.xda-developers.com/showthread.php?t=2432476 ) its the 2015 method that i downloaded.
so what do i have to do, i havent tried using different usb cables, the port seems fine to be plugged in since in TWRP it says 84+ so i meant its charging right? help me out guys idk what else to do or flash or anything.

I think the methods leave out that you need to change your phone to com port 41 on device manager > ports in order to be detected. Then you need to unplug it and reconnect to computer when the program shows waiting for device, with the phone in download mode already.
Also, to get to recovery you hold vol down and power, when the LG logo comes up release power and hold it again until the reset screen comes up.
To get to download mode you turn the phone off then hold up while plugging the USB cord in with it connected to pc... This launches download mode.

Well you see man , I cant change anything in Device Manager since my phone isn't being detected. It didn't install drivers fully fully since my phone isnt recognized. Even in TWRP or "Download Mode/ Firmware Update" Nothing happens no drivers installing or anything even but it does boot it up to that point....and its just normal boot up i see the LG logo and my led goes from green to blueish in a smooth transition and it doesnt stop until i turn it off. The method i got into recovery is holding all those buttons down its not a problem for me to get into it. I also have another problem it doesn't seem to want to mount my usb otg by samsung.
what do i do
So i tried the otg route but I can't mount it. I have everything connected and once I go into recovery to mount usb-otg, nothing happens.
I just need some way to get a ROM.zip in my phone
Computer does not recognize my phone.
Stuck at LG logo unless I enter recovery.
Sideload doesnt work.
OTG doesnt work.
I've tried at least 4 different guides with no luck.
Why don't you manually install drivers from online?

ive tried that already and it doesnt list anything from the LG folder.
I realized the phone will say start the adb sideload feature. so, when i put the "abd sideload file.zip" command on my pc i just wait a few minutes and it says daemon not running on port 5037 and then start successfuly and then error :device not found.
it can seem to reognize my device wether its in recovery, or download mode or fastboot mode.
Try again in other pc that has never been conected to an LG Phone before. It can perfectly be a conflict with drivers installed in the OS.
I've tried man
AFter i cleaned the usb port in one of the chats or forums, i waited a day ovbiously without turning on the phone and cleaned the usb port with alchohal and a q tip and i plugged my phone into my computer and my PC detected something but it only says "Unknown Device" everytime no matter what pc i use it says that. nothing else. but before that none of my pcs would detect theirs a phone plugged in at all.

No there is no problem with your USB cord or port. You need to do following steps.

Bricked Oneplus 2 (SOLVED)

**UPDATE I have unbricked my phone and the whole time I thought it was a software issue on my phone but it was a cable, I guess my cable got broken when I bricked my phone and I thought it was a software issue but it was not the whole time**
I have a bricked device and I would appreciate your help and I have tried EVERYTHING!!
here is how my oneplus 2 got bricked, I was on stock oxygen os 3.0 and rooted and I had twrp recovery 3.0.
So I did a full wipe on my device and when I was flashing the resurrection remix rom in twrp it said "Error 7" so then I reboot my phone and I was in a bootloop with no os.
I went back to twrp and flash the rom again and it not work. So then I tryed to transfer a file through my computer to my device and twrp was not recognizing it and tryed adb sideload and same thing and even in cmd I
typed "adb devices" and it not recognize it and I have the drivers installed, the 15 second 1click adb and fastboot.
And then I went to fastboot mode and then I tried first aid kit and the qualcomm mega unbrick guide and all the methods and still my oneplus 2 is not being recognized by PC and I am using the official oneplus 2 usb type c cable.
I have tried 2 windows 10 PC and I turned driver signniture enforcement off for the qualcomm drivers and nothing in device manager
I tried 1 Windows 7 PC and same thing and nothing in device manager
And I tried a Linux Mint virtual machine and I typed adb devices and fastboot device in the terminal and it was not recognizing it even though I installed the packages
So do you think the problem might be the cable? because it is the official one. But my device charges through the cable to and the cable was working before my phone got bricked. Or is it a driver problem? What do you guys think and please help and I will really appreciate it and thank you.

If your recovery mode is TWRP.. Then goto Mount -> Data
Then your computer will show your oneplus 2.
If still its not showing then update Driver Software of phone in device manager.

I tried both mount data on and off and still no luck, I have mtp enabled in twrp. I also checked device manager and there is nothing showing up. But twrp says that my phone is charging when my phone is connected to pc. I think the problem is probably the cable because the usb end of the cable looks sort of damaged, And I tried a Type-C OTG and put a usb on that and TWRP was not recognizing it

Holy crap the cable was the problem the whole time!!! I just went to the store and bought A new 3rd party USB-C cable and I plug it in to my pc and phone and immediately the pc installed drivers and now I could transfer files to TWRP from my PC!! It was a really hot sunny day today and I walked to the store which took 30 minutes and both ways 1 hour. I am so tired right now from the walk but it was worth it since my phone will be brought to life!! I am so happy right now!!!

H E L P - bootlooping, COM does not recognize phone

Hi everybody,
ill try to make it short:
My 6p has entered into the bootlooping mode.
I have never unlocked the bootloader/changed ROM/kernal.
After I let it bootloop until the battery is dead it's changing from bootlooping into blinking red dot. Then when I charge it for a couple of minutes it comes back to life after 10~ min it's bootlooping again - so I have a window of possibilities to play with the setting. In that window I have used the "OEM unlocking" option.
In the bootlooping state when I boot into the bootloader and connect it into the PC the device doesn't recognize that it has been connected and a PC ,and the PC recognize a entry of new device but doesn't recognize it is a Nexus 6p.
this situation is the same when I connect the phone when it is alive.
I have installed adb and fastboot with this software
https://forum.xda-developers.com/showthread.php?t=2588979
with the 1.4.3 version it shows in the end of the process "0 files copied" and then I tried the 1.3 version and it showed that 4 files were copied but it also showed an error.
I have also downloaded ADB from google site but it does not work either.
When I try to open the powershell in a folder where I have downloaded an img and type in a fastboot command the computer doens't recognize any type of command.
So if anyone can help me ill be glad.
Thanks in advance,
Matan.

What is the new device identified as....Qualcomm HS-USB QDLoader 9008? Your phone may be stuck in EDL mode. If that is the case you need to search XDA and attempt solutions for that problem first.
Did you previously have your PC setup properly with the correct USB drivers and it was working OK, or just now trying to get your dead phone to communicate? If the former it may be the EDL issue above. If it was the latter, the communication problem may just be the drivers were never set up in the first place. Have you tried a different cable or port on your PC, or another PC?
With no access to the OS you will be unable unlock the bootloader or access to ADB because those have to be enabled FIRST in the OS, so there's no helping you here until you can actually boot into the OS. Do you have access to Recovery mode? Tried a factory reset? If you don't have recovery, that was a major omission.

Bootloop/ADB/Data Recovery - Phone Not Recognized With Correct Drivers

I am trying to recover the data from my old bootlooping LGV20. My drivers are updated. When I plug my current, working LGV20 into the computer, the phone is immediately recognized and the driver is listed as LG v4.2.0, the most current in Device Manager. The phone is labled as its model number in Devices and Printers. When I plug in my old V20 (which has full access to stock recovery and download mode but does not boot) the computer recognizes something is plugged in, but in Device Manager the device doesn't show up. In Devices and Printers the phone shows up, but as "LGE Android Phone".
Summary:
When a working LGV20 is plugged in, it is recognized and the latest 4.2.0 driver is used.
When the bootlooping phone is plugged in and completely off, it is only recognized as "LGE Android Phone"
Not recognized in Recovery mode
Because of this issue, I cannot use adb on the phone to recover my data.
The phone is stock, non-rooted, android 7, LG-VS995. I have the usb debugging option in the recovery menu though the phone bootloops when this is selected.
ADB installed via 15 second installer and SDK.
"ADB Devices" returns nothing.
When in Download mode, "Fastboot devices" returns nothing.
This issue was repeated on a second computer.
USB 2.0 and 3.0 tried.
The phone is recognized in LGMobileSupportTool
In Download mode the phone is recognized as "LGE AndroidNet" in Devices and Printers and as a COM41 port (changed from 7) in Devices and printers.
What do? I'm at a loss and it feels like I've tried everything.
Edit: I've successfully dumped the phone via LGUP, tried flashed a new image, phone is still bootlooping. Is there any way I can browse the userdata dump file?
