the original post is here(http://infinityconsole.org/forum/guide-e-modding/549-guida-al-debrick-del-nintendo-3ds.html), which is written in Italian. But I can't read Italian and the Google Translate sucks when the post is translated in Chinese.(English is better, though) Then I tried to read in English and get some of the main idea. (Sorry for my bad English) You must have the NAND backup or the Emunand Backup from softwares like Emunand Tool which belongs to your own console. These steps are followed using Windows, not a Mac. the main idea is to do the hardware mod on the 3DS and plug the modified SD card into a Raspberry PI.(something like a small computer with SD card and Internet support,about 35 dollars in China) Then you should connect Raspberry PI and the Windows PC in the same network. Then fix the eMMC with PC and Raspberry and finally flash the original nand with backup. Details are translated into English version (I'm not resopnsible for the translation!) http://translate.google.com.hk/tran...ng/549-guida-al-debrick-del-nintendo-3ds.html I wish someone would make a better translation.
