Another bricked phone. Yes I read the main threads

D801
TL;DR: Phone will only boot into download mode, however computer won't recognize my phone.
I installed all the drivers, have multiple versions of flash tool, even tried sideloading via ADB but device isn't recognized. How do I unbrick my phone?

Download and install the Minimal ADB and Fastboot tool v1.1.3...

While in Download mode and w/ USB Debugging enabled, double click the Minimal ADB and Fastboot shortcut, then at the Minimal ADB and Fastboot> prompt type... adb devices
If your phone isn't recognized by ADB, then you don't have the correct drivers installed.

[Q] how to enable usb debugging - screen broken

My s4 display is broken, so, there's nothing that I can do with the phone. When I connect phone via usb, I'm able to browse through folders on my s4, but in adb, on "adb devices" command, none of devices is listed.
Phone is rooted with CM11 ROM installed.
When I connect phone in recovery mode on bootup, and open adb, all commands are working, and device is recognised.
Is there any way to enable usb debugging from recovery mod, so device would be recognised in adb when it boot up normally?

You could try this:
Run an ADB shell in ClockworkMod
Remount /system in readwrite mode.
Add this to /system/build.prop: persist.service.adb.enable=1
Save the file.
Warning: Some people reported that this causes their device to not boot anymore.

hi... i have sme problems...
adc say me that phone is "unauthorized"
can you say exactly tha command that i must use with adb?

[Q] Can't ADB in bootloader mode?

I can ADB/fastboot my device most of the time.
But when booting into Bootloader mode, I suddenly can't ADB into it?
The driver appears to be loaded up in my Win7x64 computer. Says it's the Motorola ADB device. And I can open my files on the phone. But ADB just doesn't see the phone for some reason. Any ideas?

Bootloader is fastboot.
Code:
fastboot devices

Fastboot doesn't detect my phone, please help

I want to install LineageOS so I closely followed the fastboot and adb instructions on the official site. During my first (failed) attempt, there were some old Google USB and ADB things on my PC, so I deleted everything and started again with a clean slate.
I managed to make ADB work (adb devices detects my device, could authenticate the computer, all seems good there). But if I start the phone in fastboot mode, connect and run fastboot devices, I get nothing back. It doesn't give any sign of the connected device. Windows's "Devices" window lists a device called "Android", but it's under "Unspecified" and has the yellow triangle/exclamation mark on the icon.
1. Am I right to assume that this will stop me from unlocking the bootloader (if I will use the unofficial method) and flashing TWRP and a custom ROM on the device?
2. More importantly: What could be wrong, how can I make fastboot see my phone?
Many thanks for the suggestions!

hi,
first do you have latest ADB and Fastboot
then connect your device and run adb devices. check if it detect the device means from the command prompt run "adb reboot bootloader" (without quotes)
now once after device reboots to bootloader check fastboot devices it will detect now
if not then goto device manager,right click on the device and click on update driver software and choose android fastboot interface
you are done now run fatboot devices,it will detect the device

Solved!

My phone is not recognized in ADB console while running fastboot mode

I wanted to install a custom rom for my moto g4 and I just have problems with installing twrp. I downloaded twrp img and adb tools, then connected my phone to the pc in debug mode. In the adb console, the phone is displayed, but when I put the phone in the fastboot mode, it is not recognized.

that's cos there's separate program (e.g. fastboot) for interfacing with bootloader (c.f. Android Debug Bridge for interacting with recovery or Android).
