2D42 Does not turn on after failed update!! Help!! Please!!

elison

Hello, I have a 2c42 and at the beginning of the firmware update my PC crashed and restarted.
The oscilloscope now does not turn on, when I connect it to the PC the on / off button remains on and if I remove the batteries and reconnect the on / off button it is flashing.
Is there a way to recover the oscilloscope ?? I was also reading some posts that use a usb adapter module ttl rs232 pl2303 hx how do I do this step by step and what files do I use? I took a look at this dolink video https://www.youtube.com/watch?v=-uF2fdVxx1E
Help please !!
