UPDATE: There is a simpler, easier and faster procedure here that can work for most people. Please see if that works for you before venturing into this procedure.

Introduction:

If your device is unresponsive, or you were not able to have the initial upgrade completed due to a lack of HDMI connection, you can follow the instructions below to bring your Monument up to date with the latest firmware. This step is only required once, and your Monument will be able to self-update over the internet subsequently.

You will need a spare SD card and a computer to complete this process. Please follow the instructions below to prepare the SD card. This process is separately explained for Mac, Windows and Linux computers.

Once you prepare the SD card, power off your Monument, unplug any USB drives and plug in the SD card, and power it back on. The LED in front of the unit should flicker in different colors, and the whole process should take around 5 minutes. Do not interrupt the process until you see a solid green color. At that point you need to remove the SD card and the unit will reboot itself with the latest firmware.


Preparing the SD Card

You will need an SD card and a computer. Please note that all the contents of the SD card will be destroyed, and you will need to format the SD card to use it again. 

Download the file here. You may need to unzip this file by double-clicking on it. Instructions for Mac, PC and Linux are provided below.

Mac / OS X

  • You will need to download a free software, Etcher to prepare the SD Card. Please download this software using this link: https://etcher.io
  • Plug in the SD card into your computer. If you don't have a built-in SD card slot, you can use an external SD card reader. 
  • Open the Etcher software. Press "Select image" button and browse the unzipped file: recovery_sd_20170506_204.img

  
  • Select or confirm the drive where SD Card is inserted. 
  • Press "Flash". You may be asked to enter a password of your computer; please enter your password. 


  • This process may take a few minutes. 


  • Once the process is complete, you can remove the SD Card from your computer. (If your Mac displays a dialog box stating "The disk you inserted was not readable by this computer", please click ignore before you remove the SD card.)



PC/Windows

  • You will need to download a free software, Etcher to prepare the SD Card. Please download this software using this link: https://etcher.io
  • Plug in the SD card into your computer. If you don't have a built-in SD card slot, you can use an external SD card reader.
  • Open the Etcher software. Press "Select image" button and browse the unzipped file: recovery_sd_20170506_204.img 




  • Select or confirm the drive where SD Card is inserted. 
  • Press "Flash". You may be asked to enter a password of your computer; please enter your password. 


  • This process may take a few minutes. 



  • Once the process is complete, you can remove the SD Card from your computer.


Linux

Please note that the  dd tool can overwrite any partition on your machine. If you specify the wrong device in the instructions below, you could delete your primary Linux partition. Please be careful.

  • Run df -h to see what devices are currently mounted.

  • If your computer has a slot for SD cards, insert the card. If not, insert the card into an SD card reader, then connect the reader to your computer.

  • Run df -h again. The new device that has appeared is your SD card. The left column gives the device name of your SD card; it will be listed as something like /dev/mmcblk0p1 or /dev/sdd1. The last part (p1 or 1 respectively) is the partition number but you want to write to the whole SD card, not just one partition. You therefore need to remove that part from the name, getting, for example, /dev/mmcblk0 or /dev/sdd as the device name for the whole SD card. 

  • Now that you've noted what the device name is, you need to unmount it so that files can't be read or written to the SD card while you are copying over the SD image. Run umount /dev/sdd1, replacing sdd1 with whatever your SD card's device name is (including the partition number).

  • Run the following command, replacing the last part with the correct device name:

dd bs=4M if=recovery_sd_20170506_204.img of=/dev/sdd

 

  • Remove the SD card from the card reader.
