### Build your own DietPi image:

Watch out this is an ardous process. 
Updating from a v6.14 DietPi image is causing a bootloop under some circumstances. Will be sorted once the current, >6.2 version is uploaded for the Odroids.  

* For the Odroid HC1 / HC2 / XU3 / XU4 the start is this image:   
https://dietpi.com/downloads/images/DietPi_OdroidXU4-ARMv7-Stretch.7z  
* Burn it to the SD with [Etcher](https://www.balena.io/etcher/)


* In the desktop terminal on Linux / MacOS or Putty on Windows:  
`ssh root@[IP-OF-DIETPI]`  
password: `dietpi`  
Getting started with DietPi: https://dietpi.com/phpbb/viewtopic.php?f=8&t=9#p9  

* Ok > Cancel > Cancel  
automatic apt update & apt upgrade and asks to reboot
![](pictures/dietpi_1st_reboot.png)  

* Log back in:
`ssh root@[IP-OF-DIETPI]`  
password: `dietpi`  
* after the update the ssh keys might change:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@  
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @  
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@  
run (can be copied from the terminal output):   
`ssh-keygen -f "/home/[your-linux-username]/.ssh/known_hosts" -R "dietpi.IP"`  
`ssh root@[IP-OF-DIETPI]`   
yes >   
password: `dietpi`  

* At this point if the DietPi OS was not updated from 6.14 it does not manage to save settings going forward.  
Exit the software installer (press Tab to jump to Exit)
![](pictures/dietpi-software_exit.png)  

* in the bash prompt run:  
`dietpi-update`  
Ok > Cancel the recovery point   
update > Opt out of survey > Ok  
Reboots

* Log back in:  
`ssh root@[IP-OF-DIETPI]`  
password: `dietpi` 
* In the DietPi software menu install fail2ban and make OpenSSH server the default SSH server.  
Ok > Cancel > Cancel  
Search `fail2ban` > Space to select > Enter  
SSH server > switch from Dropbear to the OpenSSH-server  
Install > Ok  
Opt out of survey > Ok  
Reboots again

* Log back in:  
`ssh root@[IP-OF-DIETPI]`  
password: `dietpi`  
Changing the SSH server will change the SSH keys again. To clear:  
`ssh-keygen -f "/home/[your-linux-username]/.ssh/known_hosts" -R "dietpi.IP"`


### Run the RaspiBlitz build_sdcard.sh script

* Format of the command to build the SDcard:  
`wget https://raw.githubusercontent.com/[GITHUB-USERNAME]/raspiblitz/[BRANCH]/build_sdcard.sh && sudo bash build_sdcard.sh [BRANCH] [GITHUB-USERNAME]`  
If you are working from a forked repo be aware of that the fork needs to be called `raspiblitz` for the git downloads to work.

* Run the forked version of @openoms:  
`wget https://raw.githubusercontent.com/openoms/raspiblitz/raspiblitz-dev/build_sdcard.sh && sudo bash build_sdcard.sh raspiblitz-dev openoms`  
This will take a couple minutes depending on your internet ceonnection and the processing power of the SBC.

* Restart when done and log back in now as `admin`:  
`ssh admin@[IP-OF-DROIDBLITZ]`  
password: `raspiblitz`

* From here he setup continues with the [RaspiBlitz Setup Process](https://github.com/rootzoll/raspiblitz/blob/master/README.md#setup-process-detailed-documentation)
