The user reported that after updating the firmware, they experienced significant improvements in Wi-Fi connectivity and throughput. The user also mentioned that the firmware update resolved several connectivity issues they were experiencing with their device.

If your buttons or radio don't work, you may need to update the MCU file separately, which is often included in the firmware package. In reality, the hardware underlying these units typically

If power is lost during a firmware update, the unit will likely become bricked. This is a serious but recoverable situation. Do not attempt to power cycle repeatedly—connect to a PC via USB and use SP Flash Tool to reflash the complete firmware package.

Minimal lag on the home screen; struggles with heavy live wallpapers.
