Optiflasher can't connect to my DM920 via service port (so i can't use advanced mode), but see it in list of ports. To make it more funny i can open serial connection with terra term, but can't open it with putty. Any ideas besides new drivers sience i tried like 30 different ones?

Please check that your mini usb port driver is installed !
If you can't connect with Advanced Port & same with Putty for testing mean that there's a problem .
For Tera Term you can open connection but have you got any result of box boot any data there ?

Can do anything in terra term.
