Hi all, I'm pretty sure I haven't seen a working solution to this problem, but here goes... I have a 1.4 DSi and got an R4i SDHC Upgrade Revolution. I put the proper firmware on from the site i bought it from, all was working well - then i think I updated using some option somewhere in the shell or game engine or something! Now it screws up when I go into the game browser, and also when I go into the media browser and also the WiFi Engine bit, too - formatting the SD card doesn't work, and I've replaced the firmware from 1.09b (doesn't work at all) up to 1.22 (loads, but doesn't work!). Nothing below 1.16 even loads - all I get is "menu?" otherwise. My recurring error is a black screen with the red writing "Please upgrade the hardware for support latest firmware." Any help on this would be awesome - I've been searching for 7 hours with no luck. Lots of people posting the error (in various languages) but no common root or solution!! Is the problem something gone wrong in the R4 cart itself? Can that happen? Is there a way to access it?
