I've been trying to update the software on my RNS-E from 0020 to 0270. I have the files for 0200 and would eventually like to install a BU camera, hence the hacked version. I've tried 3 different computers with 3 different versions of Windows (all 7 and higher) and have no luck. I have tried both Windows disc burning software as well as a copy of Imageburn. In most cases the disc will start to install the software but then display a line of Asian symbols, then the typically Audi startup screen then finally the nag screen, this goes in an endless loop until I eject the disc. In other cases, I could not eject the disc at all and then in a third it said the disc was unreadable. I have also tried to install version 0200 thinking my editing was bad but got the same results. Any suggestions?
