Bricked Xiaomi Router 3C (R3L)

While flashing OpenWrt I bricked my Xiaomi router 3C (R3L). But I was unable to debrick it following the debrick method outlined. I was able to get to the firmware image upload page but after I upload it, the router hangs and remain in an unresponsive state (waited for 6 hours) showing in the web interface that it is restoring.
