i have the onn 4k device and is trying to update but everytime i get system failed. The factory reset option doesnt work either. when i hold the little circle button to get into recovery mode it just turn on to android tv normally. I can use the device, i just cannot factory reset or get into recovery mode. this has never happen before, i am so confused how that can happen. have i bricked my device?
If it boots and is usable it's not bricked. Check your available disc space, it may not be enough to do the update.
