Unfortunatelly I could not find any docs related to my issue, so I hope someone can help-me.
I would like to know how I can remove Balena OS from a Rock Pi 4, so I can run another OS from a sd-card.
I got an Rock Pi 4 which has no sd-card or Usb attached to it and when I start I just see a green Balena OS splash screen forever. By pressing ‘delete’ usb keyboard I can see a task running saying ‘start job is runnig … bluetooth firmware’. I tried to press a lot of buttons, but I couldn’t get to a terminal.
By now, I got this Rock Pi 4 from a random company which was going to dispose a lot of unused hardware and placed them for anyone to take.
I tried to flash a new OS and insert a sdcard but it’s never booted. It’s always end-up in this Balena slash screen. And as I said, in the original thread, I get this Balena splash even if there is no sd card inserted in the Rock Pi 4, so I guess it might be some custom firmware for belana cloud
