Need to unbrick treble-partitioned, stock-flashed and boot locked device

[antkov]

I have spent the last couple of days trying to figure out how to restore my Mi A1 to a state where it can boot into a ROM. Currently, it's stuck in a boot loop.

Earlier in the week I followed the guide to go from stock to treble, but then decided to go back to stock. I used MiFlash to flash to stock and that's when it started to boot loop. I realized I hadn't used the TWRP with TISSOT manager to de-treble-partition the device and I also let MiFlash lock the bootloader.

I have removed the back cover from the device to get it into EDL mode, but am not sure how to flash a bootable ROM so I can unlock the bootloader and boot into TWRP. I have tried re-flashing stock but it just boot loops again.

Any suggestions?

I didn't have an EDL cable so I shorted the test points after pulling the back cover off.
