If you encounter problems with your MAG256 such as frozen channels or abnormal slowness due to a malfunction, I strongly recommend that you follow the instructions given below:
Press and hold service button (FN) on back side of STB until STB is power off, or during 2 seconds after power on. Switching between modes done by releasing button at specific time according to LED indication.
There are 4 modes:
Mode 1. STB load from first U-boot - Press and hold service button, power on STB. Wait until LED indicator change it's mode (LED is white, slow blinking). If button button will be released STB will load in mode 1. Not releasing of button - STB will go to mode 2.
Mode 2. Switch to alternative NAND - (White LED, fast blink). If button button will be released STB will load in mode 2. Continue to hold will result in - go to mode 3.
Mode 3. Reset to default settings - (Red LED, fast blink). If button button will be released STB will load in mode 3. Continue to hold will result in - go to mode 4.
Mode 4. “Emergency-mode” - STB Boot from USB/DHCP - (Red LED, without blinking). If button button will be released STB will load in mode 4. Continue to hold will result in - Standard load.
