Hi, can me help any one?

I upgrade my MI 8 to MIUI 11 (Android 10.0, beta on 25 dec.).Success.
Then downgrade (with format data) to
* xiaomi.eu_multi_MI8_V10.2.2.0.PEACNXM_v10-9.zip
with
* Disable_Dm-Verity_FEncrypt_21.10.2019.zip (for GPay)
by twrp-3.3.1-1-dipper
Now, i have blocked phone (starting screen "MI.com") without restarting to fastboot or twrp or china bootload menu
I haven't unlocking permition. How i can recover? May be any have same account with mi-flash permition?
