I downgraed my old 3ds xl emunand from 10.3 to 9.20 us and my Meunand stopped booting as I get a grey and white screen so I started from scratch. Before I reformatted my SDCard I booted up to sysnand and used the web browser to access Rxtools which flashed the Rxtools screen then turned back and does nothing. I reformatted the SDCard and followed the Tut to reinstall cfw. At this point I am able to boot into Homebrew channel just fine using emunand 9.20-20 and sysnand 9.2.0-20. When I installed the CtrBootManager-1.2 by coping the boot.3dsx and boot.cfg to my SDCard and renamed my old boot.3dsx to boot_hb.3dsx and choose to boot from RXtools the screen would glicth and turned grey and white again. I deleted the boot.cfg and boot3.3dsx and renamed boot_hb.3dsx then my #DS would bootup to the Homebrew channel from coldboot. I tried the latest nighlty build of RXtools and get the same results. Anyone have any ideas?
