• Flash in a stable power environment – Use a UPS (Uninterruptible Power Supply). A voltage drop during erase = death.
• After successful flash, do a factory reset: Hold the reset button for 30 seconds.

Risk of Bricking: Incorrect firmware can permanently disable the device.

For advanced users or researchers looking to root or modify devices, community forums and GitHub repositories provide detailed technical workflows.
