Hello, I have a redmi 6A that tries to downgrade the miui version from 11.0.8.0 to 10 and now it does not power, it only vibrates and in the operations log it does not show the "android system info". What would be the correct steps to unbrick this phone? I have the backup but I load it and it still does not show the "android system info". I am new with this box

I already saw all the training videos. I follow the guides of some of them but I'm not lucky. If I load the operating system directly to the emmc from the "factory image" tab, the phone should turn on? I have tried different versions (miui 11, miui 10) and it doesn't power on

You load the operating system directly to the emmc from the "factory image" tab and factory reset in the ufi emmc, the phone turn on if you show firmware version in the ufi and compatible your phone.
