So I was going to unlock my boot loader and do all the fun rooting things now that Magisk is working, and when I got to the point of entering fastboot to run the necessary commands, it would just reboot as soon as I entered fastboot mode. To be clear, I turned off my phone, waited a bit, power+vol down, saw the fastboot screen for <1 second, then it started booting.
So I tried unplugging from USB, and could get into fastboot fine, and stay in it as long as I wanted selecting whatever options I wanted, then, as soon as I connected the USB cable (that came with the phone), it would reboot.
So I did a factory reset, didn't set up a pin, fingerprint or anything similar, same thing, about a half second of the fastboot screen, then a boot screen.
I tried booting into fastboot with adb, same thing.
I'm not sure what is happening here, and I've never had this kind of problem before. Anyone have any advice?
I would try using a different cable, and/or a different USB port. I've seen and experienced it being very picky.
My new rig I built has us 3.0 on the front and 2.0 in the back, my pixel absolutely hates being plugged into the 3.0 port, when I plug it in, it does nothing but spam connection/disconnection, once I plugged it into a 2.0 port it works fine
If you are using any kind of hub or extension cord remove them and plug in directly to the PC. I had this problem on my 1st 2XL but so far the 2nd hasn't given me a problem. I did move my PC closer to my desk to eliminate any extensions I had.
EDIT: I'm using my old USB cord from my Pixel 1 plugged into my USB 3.1 port.
Ah, I only have one USC C cable and one USB C port. I'll grab a USB A to C cable after work. Will update in about 9 hours.
Thanks!
USB A to USB C cable did it. Thanks for the help!

Hi guys. i recently noticed that when i connect my desire to pc it's not coming up with any removable disk on pc, i've installed htc sync, on my phone i tried connecting it with 3 different roms, none worked, when i put card in dad's phone, pc find it. any solutions?
Which Rom are you using? On most roms, there is a storage option in the notification area which you can select.
atm i've got runnemede aio 6.0.4 but as i stated, it also didnt came up with notifications in mildwild rom and insertcoin rom
It might just be a bad usb cable. When you plug the phone to the computer, do you hear the common sound you hear when you plug a device to the usb port? It's possible that the data wires of the usb cable is broken while the wires for the power is still okay that's why it's charging and not detecting it's plugged in to a computer. Try to test it with a different cable.
If it's the same result then you can consider checking the phone and the computer ports.
Did you check Menu>Settings>Connect to PC>Connection Type ?
USB Cable, USB Port on PC or Phone.
Try connecting to another computer, that way you eliminate the phone.
Then try another cable.
If that doesn't work my guess the USB Port on the phone is dead. Flashing a new O/S may fix it, but I doubt it.
tried 2 diff nokia microusb cables, both charged only and for nokia phone (6500s) mass storage worked, damn i hope its not phone
So I installed the latest Samsung drivers on my Win 7 desktop with the intention of using mskippen's Note 2 toolkit to do a nandroid backup of my phone. After rebooting the behemoth I plugged in a USB cable into an open port and then plugged in my phone. The screen of the Windows machine went black and the cooling fan kicked into high gear! I couldn't even do a three finger salute (ctrl-alt -del) to get to the boot menu. I had to YANK the power cable!! I rebooted and tried again, same result. WTF!
Has anyone ever seen this happen before?
Before you suggest reinstalling the drivers - I rebooted the desktop one more time and plugged the phone in even before the computer had a chance to initialize the USB controllers (I.e, during POST) and the exact same thing happened. Seems my phone is out to literally assassinate my desktop. But here's the kicker - I've successfully plugged this phone into the computer before. So what is going on?
Anyone?

Sounds like a short circuit, try a different cable, try a different USB port (preferably one on the back of the computer).
FYI, USB ports are hot during POST (otherwise your keyboard would never allow you to get into the BIOS).

I swear I've used that same cable before to plug the phone (successfully) into the desktop, but you may be right. I'll try a different cable. Scared the s**t out of me, let me tell you.

Hi.
When I connect Pixel C to PC, PC does not recognize it and it does not appear even in device manager. (Even "unknown device" doesn't appear)
And my Pixel C says weird message "USB supplying power to attached device", which I haven't never seen. I attached screenshots of that message.
And what is worse, charging Pixel C is also very unstable. Sometimes I can charge, but sometimes I can't charge.
Of course I can't use adb command. However, strangely, I can use fastboot command in bootloader.
I thought there was physical issue in USB type C terminal because even charging was unstable.
However, the fact that I can use fastboot command means there isn't always physical issue in USB terminal? I'm confused.
I tried several kinds of USB cable, but same result. A weeks ago, there wasn't any problem in my Pixel C.
Please help me! What is the problem?
Pixel C's USB terminal has broken? I don't want to believe, though.

Asking the perhaps obvious, like when someone's car doesn't start "Do you have fuel in the tank?", did you select Use USB for File Transfers v Charging in the pull down? Also, to use ADB, I had to update the driver to a Google driver (been awhile and don't recall exactly which driver).

Adding onto this, it sounds like your tablet is attempting to supply power to your PC. Make sure its in MTP mode. Mine also works in USB for charging mode, though I run Linux.
Are you by any chance connecting by using a USB C to USB A female adapter/cable and then a USB A To USB A cable? If so (I'm no expert) then I think that the wire used in USB C to negotiate "which end supplies the power" will be grounded in the female A socket (no relevant/equivalent terminal in USB 2/3 ) and this tells the tablet "you supply the power to me"
Hello dear.
I have a problem with my p601,
I cant connected my tablet to PC.
When i connected, just charging and no any connection.. In odin or storage not show a device, adb not connected...
And when i used a charger show an red stroke on battery icon. And charging is very slowly, during night only 50%.
I'm root my device, install twrp, and install cyanogenmod, but nothing change.
Now whats your idea? How i can fix this issue?
This may be an obvious question but have you tried a different cable or charger? I always found running on stock ROM that charging was an issue unless I powered it down. I have used a 12W Crapple charger and that seems to work ok but charging has never been an endearing part of the this tab.
So in Odin you it doesn't work? Could you have some dirt or contaminants in the USB port, start with the obvious, change the cable, use a different usb on the pc or try another pc altogether.
I had same problem, i noticed that the usb port was loosen little bit, i had to open the tablet apply small pressure with plier to afjust the usb port,,,, and now it's perfect.
I have an issue very similar to this thread: https://forum.xda-developers.com/nexus-7-2013/nexus-7-2013-qa/unable-to-nexus-7-fastboot-mode-t3966600
I got mine for parts on ebay with "power issue." It had low battery and it charged up fine overnight, but when it boots up to either system or recovery it just stays on the Google logo.
It boots into Fastboot fine, but it will not connect to my computer. Computer has the lastest Manjaro linux with android-tools and connects to my Xiaomi Mix 2S fine, but neither "fastboot devices" or "lsusb" will show anything about the nexus, in USB 2 or 3 ports.
I opened it and reseated the silver cable between the boards, and also tried several different micro-usb cables, no dice. The port and circuit boards look completely fine. The screw seals show that it has been taken apart before.
I was not able to boot it to enable usb debugging, does fastboot need that?
Update: I did actually get it to boot, when I opened it I unplugged the battery and held the power button for a while to drain all the power. Fastboot still does not work, but I was able to factory reset it and install the last two updates. Curiously, I cannot connect to it with USB, maybe the data lanes are dead? And then after using it a half hour, it froze and I had to hold the power button to turn it off, and now its back stuck at the google logo.

It's a different USB issue but the measurements must be the same.
