Specific information for HD51 new bootloader V1.07-r19.

The file can be download at:

The easy way to check the bootloader version is by going to Menu > Information > About

Alternative using the CLI to check the bootloader version you have... Enter the receiver with telnet, enter the following command:

#:/cat /sys/firmware/devicetree/base/bolt/tag

Notice: This update is imported if you make use of the boxmode function. (Boxmode 1 is default and boxmode 12 activate PiP)

the update goes the same way as flashing a image. The HD51 folder on the USB disc must be clean before placing the content of the zip file on the USB disk. The zip file contains 2 files: hd51-bolt.bin and imageversion

There are two ways to place the boot loader on your receiver: Option 1: Press the standby button for 15 seconds until BOLT appears on the display. Option 2: Start your receiver via the power plug and hold the standby button until BOLT appears on the display.

The flash procedure will only take a few seconds and when Complete appears at the display, the receiver will restart. Warning: Do not unplug the receiver during the update process!


Boxmode for HD51 how to...

There are currently two box mode options for the HD51.

  • Mode 1 = 2 video encoder for main screen
  • Mode 12 = 2 video encoder for main screen + 1 video encoder for 2nd screen (PiP)

To alter your receiver into a different box mode Goto folder: /media/mmc/STARTUP default:

boot emmcflash0.kernel1 'root=/dev/mmcblk0p3 rw rootwait hd51_4.boxmode=1'

if you alter hd51_4.boxmode=1 into 12, your receiver is switching to boxmode 12 when you restart your receiver. so:

boot emmcflash0.kernel1 'root=/dev/mmcblk0p3 rw rootwait hd51_4.boxmode=12'

Must I switch from mode? The answer is no. If you switching into box mode 12, the energy consumption will increase.
