Does the device gets detected in fastboot?

It is hard brick I guess.. I'll recommend you to take it to the mi service center or if you have basic knowledge about test point method then try it out. You can get the number of videos on youtube or threads of xda regarding test point methods

[Help] Oneplus 7 pro Bricked with locked bootloader.

My one plus is stuck in Qualcomm crash dump mode, It won't boot into recovery mode, but id does boot fastboot mode, I cant use adb to flash it because my bootloader is locked, adb cant recognize my device. I have tried QDL mode to use Guac msm download tool but it does no good, Can someone tell me what am I doing wrong?
Your best bet is to read up on the msm tread. A lot of answers can be found there.
With a locked BL , I can only suggest msm tool. Personally never got it to work myself but I unlocked my BL as soon as I got my phone so I used fastboot ROM to fix it. Best of luck
