Any hope for turning on phone Nokia 7.1 using adb

My power button died on my phone. Or got less and less responsive. Last time I was lucky that trying a long time I managed to start up my phone. Since then I kept my phone on perpetually or restarting it if that was required. However, now my phone just suddenly turned off out of nowhere. I tried to turn it on again but had no luck. I had previously turned on USB debugging since I thought that was enough to turn it on from the pc if it ever got turned off. Now it seems that was not enough as it shows up as unauthorized in adb (I never tried actually connecting, very stupid on my part). Is there any hope for turning my device on through adb.
Phone: Nokia 7.1
There are some questions on problems with unauthorized devices (ADB Android Device Unauthorized) but those seem to assume I can still turn on my phone to change settings. Is it impossible otherwise?
tldr; Here is a detailed list of instructions if you want to try your luck with fastboot. Your touchscreen and volume buttons must be functional for this to work.
Make sure the phone is turned off.
Press and hold the Volume Down button. Don't release it.
Plug in a USB charging cable
When the screen turns on and shows a message saying "Download" or "Fastboot" mode, release the Volume Down button.
Charge your phone like this for 2 minutes, to make sure it has enough charge.
Move your phone's USB cable and connect it to a PC.
Download the binary for fastboot.
Run fastboot continue.

One Android device run adb logcat against another

I had always wondered if it was possible to have on android device collect logcat from another. Consider the following image I have attached. The goal would be to create an application that could find and attach adb to another device.
This would eliminate the need to carry a laptop or PC to collect information for a device. Any help with this would be amazing.

Nexus devices not recognized by adb

Adb does not recognize my Nexus devices but does recognize my Samsung Tab 2 7 inch tablet.
C:\Users\Allen Edwards\AppData\Local\Android\sdk\platform-tools>adb devices
List of devices attached

The device recognized is the Samsung. There are also a Nexus 5x, Nexus 4, Nexus 7, and Nexus S connected.
In Windows Explorer I can browse the Samsung, Nexus 5x and Nexus 7 but not the other two.
All have USB debugging and are connected as MTP or as USB for File Transfer in the case of the Nexus 5x.
The Google USB Driver shows up as up to date in the SDK Manager and also comes back as up to date if I try and manually update it from a fresh download. ADB shows up as up to date when I try and update it.
I uninstalled the Nexus 5x USB driver from Device Manager and when I plugged it back in the same driver was installed which interestingly has a date of 2006. How can that be right?
It would seem logical that somewhere I have a Samsung usb driver that is interfering with the Google usb driver but I have the latest Google usb driver downloaded and point all the update drivers to that and I get that Windows says it is up to date, MTP USB Device.
The Googling I have done typically suggests things that I have done, like checking USB Debugging, or updating the drivers.
I thought perhaps Windows was getting the wrong driver for the Nexus 5x so I thought I would uninstall it and manually install it but as soon as I uninstall it, the icon vanishes and upon refreshing for new hardware, the same driver is installed.
Any ideas of things I can try?
Uninstall USB driver using SDK Manager instead of Device Manager. Device Manager just reinstalls the same driver on the next connection of the device.

Deploying to Amazon Fire TV over USB

I've been working on an Amazon Fire TV app for about a month now. The usual process of testing is to deploy over the network using Eclipse/adb. However, as the size of my app has increased the deployment time has skyrocketed. It has gotten to the point where it's painful to work on this platform and not worth the massive iteration time. I'm about to cancel the whole project!
That being said, does anybody know how to deploy an app from my dev laptop to the Amazon Fire TV over USB? I imagine that would be much faster.
ADB over USB is not possible on the Fire TV, so you can't just connect it to a PC via USB. ADB over USB is possible on the Fire TV Stick however. (source)
Your only option for the Fire TV is to root it. Rooting would allow you to connect an external USB drive to the Fire TV using stickmount. You'd then need to use an app like a file explorer to install your APK off the USB drive.

HTC Evo 4G LTE not found in ADB

I am having a problem with adb not finding my evo 4g lte. I have USB debugging selected. The phone is updated to 3.17, so some of the options, like charge only/disk drive have changed (now i think my only options are HTC Sync and disk drive). I am using the most updated version of the Android SDK. I'm running a fully updated windows 7 box. I have tried all of my USB ports, adb kill-server/adb start-server. I even created an .ini file with the hex version of the device USB/VID id (based on the HTC Sync setting, the phone shows only as Android Phone in my windows device manager. I have not yet tried switching it to disk drive), and nothing has worked. The phone's bootloader is unlocked via htcdev, but is otherwise stock. And, oddly enough, my old evo 4g which is rooted and running CM9 can be found, so I think it's got to be something with the new phone, I am just not sure what. I've been researching this over the last few days and have tried everything I have found, all to no avail. Any advice would be greatly appreciated!
Internal port is faulty. Two terminals for charging ,two for data, the data one(s) may have fractured from.the board.
