Phone bricked after flashing MIUI8 via TWRP

I flashed MIUI8 global dev rom via TWRP3.0.2.0.
The script succeeded but when I tapped "reboot system" it suddenly showed a blank screen without any sign of life.
Any solutions to this? Am I wrong to directly flash global dev rom in TWRP?
Additional info:
I did the partition mod way back. So my system partition is only 1 instead of 2.
When I connect it to the PC, it shows 7 Local Disks (different partitions) instead of the usual MTP.
In device manager, it shows up as "Marshall London USB Composite Device 9006"
I cannot access fastboot
I had same problem and I can resolved with this thread without hardware mod

In Miflash have this device?

I Bricked My Redmi K20 Pro Need Serious Help

Hello everyone. I was updating my phone with Mi Asistan from stock recovery. When updating my phone on %60, my pc gave me "dissconnected sound". When i look back the screen i saw "The system has been destroyed" I cant boot recovery mode. Only i get fastboot mode. I cant use miFlashtool for install rom or i cant flash twrp on fastboot because my bootloader is locked. I tried open bootloader but device does not have mi account.
For shortly i can use only fastboot mode but phone is locked. No recovery or anything.
How can i get back my phone with working any rom. Please help. This was my mother phone and i am in too bad situation. :crying:

Try an older version of QFIL, more specifically 1.0.0.2 or 1.0.0.3, or you can use QFIL from within QPST instead.

Flash Cust Error - Failed to check for sparse crc

Hello guys
I'm having an issue flashing the V12.5.4.0 to my Redmi Note 9.
The phone has been upgraded to V13.0.2.0 but started to boot-loop randomly.
I decided to downgrade the MIUI to V12.5.4.0 but I kept getting this error.
Same error with the MiFlashTool.
Hoping to find answers here.
Can't find anything plausible fixed with Google.
Thanks!
