Sorry for Google translate. Hello, bought ninebot es4 after rent. Flashed esc. When turned on, the display and Bluetooth do not work. When connected to the second esc, which is flashed with firmware from the lease, the display works. I tried to firmware in two ways: the telnet does not connect, the newer version shows some characters that look like an error (pictures a little later). I think the problem is in the dash firmware - there are traces of soldering on the programming contacts. I think that the tool for oem firmware gives the command to the basic firmware dash and it starts working differently. But in my case, perhaps another firmware is installed. Does anyone have dump firmware that should be loaded into the dash from the factory, or is the OEM already ready to download via the stlink v2 basic program stlink, and not via .bat?
