I'll be very happy if you guys can help me. I setup a O3DS XL friends with Emunand with MENUHAX Boot. "HE dont wanna let me do A9LH", less now that i bricked a NEW 3DS. I need help not only about cleaning. But with boot. I Alredy asked it here, but inside luma thread. But couldnt solve my problem : Warning: Spoilers inside! So my inssue it's : I'm facing failure boot with MENUHAX + LUMA3DS It's has the alredy know chance to fail with menuhax, but now i'm facing too a chance of failure with Luma3DS. Using RXtools i never got a failure with rxtools, only with Menu hax. But know it's sometimes failure with menuhax, sometimes with luma3ds, I explain, it's boots menuhax and after finish boot it's get black screen, sometimes not always. But now, lets talk about cleaning : Root my SDCARD : Some files here it's from a old Rxtools step by step tutorial provide by Yakara. Warning: Spoilers inside! luma Nintendo 3DS boot.3dsx (It's Luma3DS boot.3dsx) code.bin firmware.bin Luma3DS.dat menuhax_imagedisplay.bin menuhax_padcfg.bin ropbinpayload_menuhax_USA12288_old3ds.bin screenshots_raw.bin slot0x25KeyX.bin luma "folder" Warning: Spoilers inside! arm9-payloads emunand h&s_backup lang nand payloads sys theme arm9loaderhax.bin boot_hb.3dsx config.bin ctrbootbot.bin ctrboottop.bin firmware.bin firmware90.bin lu.dat Luma3DS.3dsx no_splash.bin patched_firmware_sys.bin splash.bin yakara.ini yakarizate.in ykr So my main problema it's about chance to failure with Luma3DS. Even we already have a chance to failure to boot menuhax, now i have a chance to boot Luma3DS. It's 2 chance of failure. I tried to start a clean setup with Luma3DS, it's works and boot emunand, but i'm afraid some of this files a need.
