ZitatIf I read the with SIM ... correctly this sounds more like a clone hardware problem ...
No, mine doesn't have "The SIM" text - it's a picture I found online. I have original one - already verified on Dreambox official website. Honestly, sending the device to dealer sounds tricky - basically I bought it online who supplied it from Germany. Probably would take a month to get new one if ever.
Anyway, if anybody could confirm whether their device's fan is spinning when device is turned on and is it spinning when in bootloader mode, it would be really helpful for further troubleshooting, fixing.
