[Q] Accidentally installed TWRP on boot

[DubultaisT]

Hello,
I today was trying to install TWRP but accidentally installed it on boot. Now my phone won't turn on.
I downloaded stock firmware and FlashTool and followed instructions on how to install drivers from here: watch?v=7pBQLVmab1M
When I launch FlashTool I get message:

04/052/2020 15:52:01 - ERROR - Drivers need to be installed for connected device.
04/052/2020 15:52:01 - ERROR - You can find them in the drivers folder of Flashtool.

There are drivers folder and I tried to installing Nicky and FlashBoot drivers but get error message

Anyone knows how to fix this, so I can unbrick my phone?
I also restarted my PC without Driver Signing Signature

Phone: Xperia M4 (E2303)
Bootloader unlocked: Yes
O/S : Windows 10

Oh well, thanks community for Your input.
Fixed my problem via installing Windows 7 on my PC.
After that could flash stock ROM via FlashTool.

TC!

Hi, sorry to bother you, I have a Bricked M4 Aqua, red light, Battery Image on pressing power button, what else other than installing Windows 7 did you do? since, I am formating my pc to install Win 7 and try to fix the phone, as I am not able to WIN 10 detect the phone.

Thanks!
