Mi 11 no more image after trying to flash update


Apr 8, 2022
hi all, I recently tried to update my Mi 11 to 13.0.9 with the TWRP (twrp-3.6.2_12-v3.9_A12-venus-skkk.img) that was in one of the bigger threads on this website (sorry, i can't find it anymore but it had a link to androidfilehost with all xiaomi devices). After trying to flash the update, I had some error messages, selected wipe dalvik cache and my screen went black. I did format data before. Now the phone doesn't do anything. No image, nothing. I can hold the power button and it doesn't turn on. I did tick the flash TWRP option before swiping the miui update as i would have needed ot afterwards probably. I can't even seem to get into Fastboot. Is there anything I could do? Or do I need to bring it to a service? About how much would I need to pay for service repair?
edit: phone is plugged in on PC. clicking the USB icon on right side of taskbar crashes my explorer. phone is probably detected somewhere as I have nothing else plugged in
