: If your screen is stuck on these words, a firmware "dump" applied via a programmer tool (like the CH341A) is usually the only fix.
Before you download anything, open your device (if it's out of warranty) or look through the vent holes. You need to match the firmware to the Mainboard ID (e.g., T2_M3821_DAKE_REV1.0 ).
Firmware updates carry a risk of permanent damage. Always back up your current settings if possible, and ensure your power supply is stable during the process.
