I only wish I had the box in my possesion so I could go through the steps from above. Thank you for your great efforts Koprajs! Quick question though, does this create an external storage on the SD or USB and not create it on the onboard internal partition for it, meaning I'd have to leave the card or usb stick in?
Yes, this creates the storage on SD card or USB drive. You have 2 options:
1. Leave the SD card or USB drive in and continue to use it (this is good if your internal NAND is not working anymore or if you want bigger or even faster storage).
2. Or you can enable SSH, login and run the tune2fs command from OP to enable storage on internal NAND. Then you can remove the SD card or USB drive.
In either way you only need to do this once (when setting this build up). Updating to the next versions will work as usual (copy the TAR file to Update folder and reboot).
