When I do bootloader unlock processing and wait for xx hours, I just check the remaining time without touching the terminal and occasionally.
I changed my Mi account halfway and waited 360 hours again.
Mi Pad 4 Plus power OFF.
volume minus Button + power Button
then fastboot mode
PC Command prompt
I am using TWRP recovery-clover-20180915.img.
