First of all, thanks for your time guys and sorry for my poor english. I will try to explain the most detail as I can. My Goal (or what I want to) 1.-Have Sysnand 4.2 with DS Profile Exploit with RXtools installed (So I can boot my Emunand without internet) 2.- Emunand up to date with FBI inyected through H&S App. In order to play CIA Games (Emunand) 3.- I dont want to use ANY KIND OF FLASH CARDS (Gateway, R4, etc) ------------------------------- So, Grab some Pop Corn and listen the story of my life: I had mi Old 3Ds with 9.0 Sysnand. I decided to downgrade to 4.2, Install Ds Profile exploit, Run Gateway Launcher and make a emunand (4.2) From here: -Sysnand 4.2 (With DS profile exploit) -Emunand 4.2 Rxtools and Gateway launcher boot emunand without problems. I decided to update my Emunand up to date (10.3 At the moment of this post) In RXMode So: -Sysnand 4.2 (With Ds Profile exploit) -Emunand 10.3 (Updating with RXtools) Rxtools and Gateway launcher WON’T boot at all. (Browser and profile exploit) I tried to update my Sysnand to 7.1 Using a Zelda Majora's Mask Cartridge. So: -Sysnand 7.1 (Without DS Profile exploit, because they patched that bulnerability) -Emunand 10.3 (Updated thanks to RXtools) Rxtools boot emunand without problems (Using browser) BUT Gateway launcher WON’T boot emunand at all. I used FBI to inject H&S app and I was be able to install cia games (Emunand) So, I decided downgrade my Sysnand to 4.2 Again and my Emunand Stops booting. But if I update (again) My sysnand to 7.1, My Emunand Works again. I don’t know why this happens. Why I can’t boot my up to date emunand having a 4.2 Sysnand. Note: I tried using, every version of RXtools, Every version of Gateway launcher without success. I tried reformating my SD card many times. I tried restoring mi Nand many times. I searched a lot’s of post without getting any solution, So I decided to make this post. Hope you can help me guys. Thanks in advance.
