Good, but have you been able to degrade or have not been able to degrade

Good, by sd card or otg with usb have you also tried? sometimes you have to leave the box or dongles apart and to experiment it is better by sd or otg card with usb and testing firmware with the same cust (C0, C432), until it lets me downgrade firmware and security patch, I don't know if explained enough to me.

Firmware options to downgrade (better by sd card or otg usb):
- TAS-AN00 10.0.0.173 (C00E170R6P2) _Firmware_EMUI10.0.0_05016BMA
-TAS-AN00 10.0.0.161 (C00E161R6P2) _Firmware_9.0.0_r3_EMUI10.0.0_05016BMA
-TAS-AN00 10.0.0.163 (C00E161R6P2) _Firmware_general_9.0.0_r3_EMUI10.0.0_05016BMA
-TAS-AN00 10.0.0.156 (C00E152R5P3) _Firmware_general_9.0.0_r3_EMUI10.0.0_05016BMA

This is the firmware that I have found online, I do not know if there will be more, there is no problem with brick, as you can see it has the same firmware cust that you have posted, you already tell me something or if you have solved it.

First i would thank you for your quick response.
and yes i've tried with otg (builds 173 and 163 same cust) without success ihaven't huawei nano memory card but i tried with OTG, it seems that HUAWEI blocks all the ways to downgrade (for the moment).
