X750 Spitz

i haven’t used my x750 for a few years and after trying to update the firmware the network port keeps cycling saying network cable unplugged and then unidentified network. were can i find the original firmware or a full version of one that will work i have tried the ones from the download site and they don’t work

I replied your email. Seems your devices is a modifed version. I suggest that you talk with the seller.
