Hello my friends, I had this problem with the Yamaha Genos keyboard and I could not fix it, during the installation of the expansion pack the power went off suddenly and when I tried to install the expansion pack again this message appeared, and when I tried to check the device and find the problem, the error appeared in the blue screen, I hope to find a solution You know, I have tried all the factory reset options, but it didn't work,
I also tried installing an expansion pack that I had already installed and it also didn't work for me
