Hello i have tried this but the situation has worsened up.
Firstly i tried to restart but nothing happened after that i tried to the recover the system by pressing F2 but this didnt work as well. In the last i tried downloaded the up file and updated the recovery file via a USB. it did perform the uploading but now when i switch on the oscilloscope it is not entering the recovery interface.
