Hold the button on the front panel and turn on the back switch.
Do not power off the device until it restarts automatically. Interrupting this will "brick" the receiver. 4. Recovery (If Stuck on Boot) If the device won't turn on, you can try a "force flash": Rename the dump file to rom.bin on the USB.
Right-click the downloaded .zip file and select "Extract All." You need the specific .bin file inside.
Insert the USB while the receiver is powered off at the back switch.
