Remember to have USB debugging and OEM unlocking in the Settings / Developer Options section. It is enabled by pressing the compilation number several times.

My method was download the firmware who wanted to lose version, unlock the bootloader and install twrp compatible with nougat that is in this same post (page 1), then flash of oeminfo corresponding to your model, example L21 / single or dual - L31 / single or dual, you must downlad L21C432 and by the method of 3 buttons install the ROM


I add links so you have quick access to information

whether oem info must be the same as the Rom,for example,oem B160 and B160 rom? Or can Oeminfo C432B130 and rom in DLoad folder to be C432B160?
I read somewhere else for returning to MM but none are like here, most say should be flashing roolback package of Huawei c900B300 and after flashin the C432B130 / 160/161
