T8SG V2.0 PLUS CARBON LOCKED

GOOD DAY I have this radio control, T8SG V2.0 PLUS CARBON arrived 2 days ago, it is blocked without explanation after the first flight everything ok I put it back home I turn it on to check the commands and stop the only thing I see is that symbol on the display . does not connect to the computer is not recognized do not know how to fix it. I read that there may be a problem on the firmware but I can't even replace it because I don't know how to enter. can you help me? sorry if the section is wrong but I am new to the forum and I am not sure that I have found a similar topic on this radio

all thanks to Alessandro

OOOKK !!!!! PROBLEM SOLVED THANKS FOR HELP !! however it is not so fast advice also to others who find themselves in the same problem of having patience during the proceeding, everything goes very slowly but in the end it works.
1) connect the radio and wait for it to connect
2) click with the left mouse button and wait a few seconds for the dialog box to open ... about 30 seconds
3) perform slow formatting to open the window I had to wait about 1 minute
4) once formatted, copy all the files present in the latest firmware available
5) disconnect the radio and restart it! everything will come back like before !!!!

thank you for the advice that was given to me
