SM-G920F - LCD broken - which boot mode? - Galaxy S6 Q&A, Help & Troubleshooting

Recovery TWRP
Hi all,
I would recover data from an s6 with broken lcd.
First time i connected it to pc via usb, it was recognized in recovery mode by adb.
I tried to access data with adb shell but no contents found in folder "data". I tought "no root permission?!"
So I installed TWRP recovery via Odin. Now, when i connect it to pc it's not recognized anymore by adb "no devices attached". I just can view "Samsung Mobile USB Composite Device" under device manager in windows and an error about MTP driver installation.
How I can determine in which boot mode is the telephone?
Could you suggest me a way to try to recover data, if present?
Thanks in advance.

additional info:
when i connect the phone to the pc trough usb, it takes about 15s being recognized by windows. next windows try to install MTP driver and it fails.
In Odin it appears "added" but if I try to flash a recovery it stucks on "setup connection"

Vodaphone Smart II (V860) Windows won't recognize phone while in fastboot mode

Hello everyone,
I'm trying to install Full Recovery on my phone using Fastboot mode. Windows recognizes the phone (Vodaphone Smart II) with normal boot mode, but when I fastboot the phone, windows sees it as Android 1.0 in Devices Manager, and fail to install the driver. And whenever I try to install/update phone's driver, windows just doesn't load it. (PS: I successfully installed that same driver while in normal boot mode).
Also, can't find any driver via windows update.
Thanks in advance for your help.

[Q] Alcatel One Touch 983 Fastboot

Trying to connect via Fastboot, device manager recognizes the phone as Mass Storage device so i can't enter into fasboot mode to flash it. I have a wrong Recovery that boots but doesn't make me select any option. Windows 8 also recognizes it as Vodafone Smart II.
I need to know:
- How can i Unbrick this device?
Notes:
- Have Adb drivers, fastboot drives, broadcom drivers, Qualcom drivers
- Have ROM Files
- No acces to operative system (I said its bricked)
- Installed a wrong cwm recovery, its boots into but no Ok button working.

p5110 Unknown USB Device (Device Descriptor Request Failed)

Hello.
So today i've decided to update firmware on my p5110.
It was already rooted and with cyan 10. I've installed TWRP 3.0.0.0 via CWM recovery and booted in TWRP. And then i chose Format data and it completely wiped out all of my files. I knew that, but i was thinking that i'll be able to flash ADB Sideload without a problem.
After that i've tried to boot into ADB Sideload, and nothing happened. My PC is not recognizing p5110. Sometimes it's showing notification "Unknown USB Device (Device Descriptor Request Failed)" in Device Manager, but most of the time it's not connected.
So, basically, now i have a tablet with working recovery, without any files on it and with no OS. I can't flash original firmware via Odin, and i can't flash it through ADB sideload, cause it's not recognized.
I reinstalled Samsung USB Drivers on my pc, installed ADB drivers and Android SDK, my other Samsung devices have no problems with USB connection, and the cable is fine.
Also, I have Windows 8.1 64 bit.
Is there any solution? Please, help.
I have exactly this same issue - running windows 10.
Following the CM installation instructions here:
https://wiki.cyanogenmod.org/w/Install_CM_for_espressowifi
Windows itself complains that the "device you connected to this computer malfunctioned and can not be recognised" and Zadig itself sees it as
"Unknown USB Device (Device desciptor request failed).
Any thoughts on this?
Cheers

phone does not recognize adb in recovery mode

I have a Huawei p20 with a broken screen and the touch does not work, after research I discovered that the only solution to get all my data back is via adb (and perhaps also fastboot), only that when I connect it to the pc it gives access, it recognizes the but the device is unauthorized instead in recovery mode it does not recognize it, but if I try it in fastboot mode it recognizes it as fastboot, how can I use adb?
