it seem your partition is encrypted.
try re flash the stock firmware first.
then, you could try flash the custom recovery again.

or u could study the stpe here, though it done on redmi 6A:

Fix HardBrick Redmi 6A (no recovery and no fastboot, only black screen)Fix without need Authotization stuff

----------------------------------------------------------------------- Finally I could fix my redmi 6A after suffering hardbrick. I couldnot enter to recovery neither to fastboot mode. My redmi 6A just give me a black screen with vibration on...

made some progress and was able to flash a custom xiaomi eu rom trough fastboot commands and so phone boots to miui perfectly.....

a problem that remains is when i boot twrp from fastboot whit "fastboot boot recovery.img" command,is that twrp shows 0mb internal memory

do you habe a/b virtual partition? or perhaps you should mount that partition

try to mount the target partition
if u couldnot mount it, then it might be encrypted

in my case to this issue:
-go into twrp
-wipe the user data partition
-wipe dalvic, cache, system, internal
-then, flash the custom rom
-reboot

hope that work for u too.
