Hello to all! I've finally decided to make the switch to Opendingux on my RG-99 and it shows. I've made a couple of videos and uploaded them to my channel in case you want to see the whole process from scratch. I just hope that I can help anyone who, like me, didn't dare to take the step.

@v47 in the video Part 2 explained how you can expand the capacity of the unit to its maximum. There is also a link to the program needed for this ;)
Best regards!
