Pic doesn't work.
I suggest downloading and installing the stock firmware via ODIN.
If it still doesn't boot after that, it may be hardware failure.

Blackscreen after flashing stock rom

After testing LineageOS over the weekend I wanted to go back to stock EMUI, so I downloaded the newest firmware from Team MT (FullOTA v167421) and flashed it via TWRP. That went through without any errors so I rebooted the phone and now I got nothing.
Basically whats described in this thread. (/huawei-p8/help/huawei-p8-black-screen-adb-recovery-t3663103 ;sorry, cant post links)I can't enter the bootloader, when connected to the PC neither adb devices, adb wait-for-device, nor fastboot-devices show anything. The only sign of life I have is in the device manager.

Why can't I install a custom ROM on my 7T Pro 5G McLaren?

I'm very familiar with rooting and custom ROMS. I received this for free with a broken screen. I was going to pull the motherboard out of it and put it in my 7 Pro body so I can get 5G.
I have TWRP installed. I've also tried crDroid (my wanted ROM) recovery on it. I've followed the instructions. What's weird to me is that my PC tells me it's an HD1910 in recovery, but an HD1925 when booted. Regardless of which recovery I boot.
When I try flashing crDroid, it tells me "Package is for product OnePlus7TProNR but expected hotdogg"
I've tried flashing the ROM in both crDroid (first) and TWRP (After it failed)
I then tried 2 other ROMs for this phone, to no avail.

I was having the same error when flashing cDroid 8.7. This is what fixed it for me:
