If you are experiencing an error when flashing MPM firmware with your T8 Pro or TX12 the radio you have may have a C8 MCU in the RF component of the radio.

later models of TX12 and T8 Pro are shipped with a C8 MCU rather than a CB MCU due to the MCU shortage of 2021. These chips are the 64k type.

Please follow this link and update your T8 Pro or TX12 to 1.3.3.0 or later.

Make sure to select the 64k Version
