[Q] Fastboot and Windows 8?

Hi all,
I have recently updated to the one and am having some trouble getting the fastboot commands working. Having been rooting/unlocking my phones for a few years now and have never really found the need to sign up and ask question as you can generally find what you need to solve most problems on here.
I have updated the driver using tutorials from here using the windows 7 ones. I have done this and everything works fine, the device is recognised. I can use the adb command to get the device connected information and adb reboot into bootloader, however when I get into the bootloader and into fastboot usb a windows notification pops up saying 'USB not recognised , the usb device connected to this computer malfunctioned and windows does not recognise it.'. As expected when I try any fastboot command it says it is waiting on device and is stuck there.
Hopefully it is something stupid I am missing out and not the device.
Any help would be good.
Thanks.

Can't root this phone

I've searched and tried most guides/fixes for adb but it fails to work when i start the phone up while holding the volume up button. The light will turn blue, and one sony fastboot driver will show on device manager but nothing else. If i turn the phone on, there is a sony adb tab with the driver and the device will show up on adb devices, but as soon as i use adb reboot fastboot it just reboots normally without going into fastboot.
latest firmware, installed android sdk,android studio, reinstalled every usb driver multiple times, downloaded xperia compact drivers from sony themselves etc. It's a ***** on a computer without a ssd.
Will provide pictures and/or videos if problem isn't apparent from description. Thanks in advance

HELP...i tried installing flashtool driver and adb 1.4.3 still dont work

do you think I need original sony cable to be recognized?

ADB / FastBoot drivers are not all you need to access your phone via USB: you must also have the OEM specific "Android USB Driver" installed on your computer.
More here: https://www.getdroidtips.com/download-latest-sony-usb-drivers/

You mean OEM driver is, my device driver (viskan,Xperia sp driver)in picture 2.everytime I manually installed it (device can't start code error 10.)
pictures 3 and 4 show that I successfully installed the oem Sao sony adb driver and still device is not detected in fastboot mode?
I even tried it on windows 7 ultimate same problem.maybe I'm missing something?

Can't unlock bootloader, due to can't connect to fastboot

Hi guys,
I want to unlock the bootloader to flash a new recovery image and to flash lineageos on my device.
But connection to fastboot will not be established whatever approach I follow.
Stock Android is updated to the last version through update function.
I followed instruction on lineageos.org and on Sony side for my device to unlock bootloader,
I installed XZ2 device driver,
I used several versions of adb and fastboot (old and new versions)#
I tried Windows 7 prof. 32 bit, 64 bit, Windows 10 64 bit Prof.
I tried USB 2 and USB 3.0 ports
Don't know anymore what I should do to get things done.
If my XZ2 is running in normal Android mode, I'm able to access the internal memory via file explorer as well as
adb devices and
adb reboot bootloader is working.
Result: LED is almost not on, maybe one can detect a little bit of blue color and screen ist black.
Then
fastboot devices or
fastboot print-pit
will not give any answer. :-(
Does anyone have a good idea to proceed before I just give up?
Many thanks in advance

strange.
had the same issues with Windows 10. had to disable Win10 driver signature enforcement to install the correct Fastboot drivers for the Xz2.
So if it doesn't work in Windows 7 either you seem to have a different problem.

A. Try using different cable
B. Install 15sec adb installer
C. Reinstall the driver again after "adb reboot bootloader"
i had the same issue and tried various method. The thing that did for me was A. Weird, since the working cable was a cheap bundle one..

[SOLVED] Windows drivers for Honor 4X (Che2-L11). Not detected in bootloader mode

Hi
I'm trying to flash TWRP on my CHe2-L11 via adb but it gets stuck at < Waiting for any device >.
I read somewhere that is because Windows lacks the necesary drivers (although Che2-L11 is listed as "MTP" in the devices connected to my computer).
Where can I find the necessary drivers for Win10?
Thanks a lot
Best,

OK, I made a little progress I think. I'm not sure my issue is actually related to windows drivers but maybe I'm wrong.
Here's the deal:
When my phone is booted and connected to my PC,
adb device
spits up something : the phone is detected. Now after running
adb reboot bootloader
the phones reboots into bootloader mode (and displays the info that the bootloader is unlocked. But from now on,
adb device
in windows CLI outputs nothing : the phone is no longer detected.
Plus now the phone shows up as an unnknown device (fastboot2.0) in windows device manager. So? Missing driver I guess? Windows can not automatically find drivers for this...
Then it make sense that I cannot flash the custom recovery until the phone is detected again.
What should I do to have my phone detected in Windows while it is in bootloader mode?
Thanks a lot

Running windows update found a driver for
Google Android Bootloader Interface
However, ADB still cannot detect it
EDIT: Actually it works! Even though
adb devices
would not list anything when the phone was in bootloader mode, I was able to flash twrp
Problem solved!
