Please can you share how you enabled the 'save_default clean' command in telnet.
I have a KCOM VMG3925-B10B which I recently bought on ebay, I didn't know it was an ISP locked version when I bid on it, I have got it to work with my ISP and it is running smoothly, but I would like to install the stock firmware and have all the options, I'm also concerened about unwanted access via TR-069 etc.
When I try to access the device via telnet I get busybox and it doesn't recognise the 'save_default clean' command, am I doing something wrong?
TIA
