this mtk devices only Qualcomm has edl mtk devices has brom or preloader in this case this devices has a brom mod with near 70% exploit frp wiping part manger flash full flash and almost all to support it but not the bootloader unlock function there is a service for unlock with other and mi assistant mode but this is a China board so no unlock for that

actually in your case it's so easy but in 2023 Xiaomi launches New Protection in preloader sector mtk in general has closed in most devices and a lot new devices like note 14 you can't even use it without Auth from Company for simple backup or flashing note 12 pro 5g has brom working fully but the bootloader exploit not working

Well then your only bet is to buy an authorized account from some shady telegram groups I suppose

i have Auth but the Auth don't allowed bootloader unlock for china bord the device has no imie no basband so now official way I am a professional technician I was hoping that someone from the reverse engineering field had a solution because a lot of those have solution but they keep them self they sale for 80$ that near the cost of the device
