Hello all. The receiver is Dm 800 Hdse Ferrari sim. I bought a new Japhar sim. First I uploaded ssl 84 all sim to the receiver, then I turned off the receiver and changed the card. The receiver starts on the display or after a second failed. I'm trying to upload the new image with japhar flasher and the process is successful. Finally I wrote box was flashed successfuly. After that, however, the second failed appears on the display. Please advice where am I wrong?
