Hello
,
I am from Germany and I will update my DSO Nano. I don’t have a DSO Nano V2.
The case of the DSO Nano looking as from a mp3 or video player. Does anyone know the name of the original player, that housing is used for DSO Nano? So we can buy a matching screen protector film that protects the entire surface.
I also do not know which firmware libb version is to be used with which firmware app Version. Some firmware packages are complete with libb and app. My DSO write “DSO201 … Ver. 1.5.20p” on start. Which firmware is now exactly on my DSO? 
How exactly do I get this firmware back to the DSO, if it is necessary, because I want also try other firmware. Can I make a backup of the firmware on the device? 
thanks for yor help
