Hello, I'll tell you the problem, the equipment is new, at first I put a wrong hack on it and it went from 200 mhz to 100 mhz but it worked well, then I tried to install an official update and the equipment stayed on the logo, the only way I could get it out of there is to install another firmware of another model, a 4-channel version, it passed the logo but everything went crazy, the tips didn't work, then I tried with another firmware and from that moment on it didn't turn on again, not even the logo and the worst thing is that you can't force the firmware installation with the green help button, I think the pre boot was damaged or something like that.
If anyone has an SPI file to get rid of that error or some other solution, I would appreciate it.
