Help with bootloader unlock

I'm trying to update the fastboot driver with the one supplied by sony in the bootloader unlock walkthrough, but when trying to update the drive manually with the z3c in update mode (blue led from volume up when connecting to usb) I receive an error saying the "hash for the file is not present in the specified catalog file." screenshot attached

BQ Aquaris X5 - Fastboot Deivce not found

Hello there,
I have a BQ Aquaris X5 and need to get into the Fastboot Mode, Android and Recovery won't boot up anymore. I can enter the fastboot mode without any problems, but if I connect my Device to the PC, I get an error message, that the USB-Deivce is unknown.

I downloaded the fastboot and adb drivers for my Device and tried to install them via Device Manager. But Windows tells me, that the best drivers are already installed... WTF!?
I installed this program: BQ_Firmware_Flash_Tool-Customer_version.zip
And this already includes the necessary drivers.
What can I do? I really need to access the fastboot mode, to restore my phone.
I would really appreciate your help.

I Bricked My Redmi K20 Pro Need Serious Help

Hello everyone. I was updating my phone with Mi Asistan from stock recovery. When updating my phone on %60, my pc gave me "dissconnected sound". When i look back the screen i saw "The system has been destroyed" I cant boot recovery mode. Only i get fastboot mode. I cant use miFlashtool for install rom or i cant flash twrp on fastboot because my bootloader is locked. I tried open bootloader but device does not have mi account.
For shortly i can use only fastboot mode but phone is locked. No recovery or anything.
How can i get back my phone with working any rom. Please help. This was my mother phone and i am in too bad situation. :crying:
