content: Quote from: @_Lis on March 08, 2016, 04:49:39 pmSo the power got pulled during a firmware flash and now it is corrupted and you can't boot.I took a similar scope apart last year, the thread is on here with photos. To investigate how to reverse engineer the software to open up some options. There are some high res photos.From recollection I believe there was a jtag header on the board. I also remember going through the update image and seeing the portion applicable to the USB processor.It's possible the USB firmware is corrupted and a reload via JTAG would get it going again.
