Flash Backup empty?

seems like i need another esp32 box to read out the firmware and then use this one only with teddycloud ( https://forum.revvox.de/t/cannot-bring-toniebox-back-to-normal-mode/919/17 )

i also have a cc3200 box. could i use the certificate from this box?

i would be happy to get some pm if anyone can help me…
