I have some answered questions to bring to the table regarding arm9loaderhax (or a9lh for short) This post *was* outdated, and may still contain obsolete information. Please try to use other sources. Is it in any state to be used yet? It is in a perfectly useable state for both o3ds(xl, 2ds) and n3ds(xl) Is anyone currently using it to boot into CFW? LOTS OF PEOPLE ARE USING IT, with AuReiNand, Cakes, and I think reiNand too. Is it recommend to go through the trouble to get it set up (risking brick)? The process has gotten a lot safer and requires less work for the user. While there is no easy 3dsx file which will downgrade you, get the OTP, and then bring you back up. There are many tools out there to make the process extremely safe. (OTPhelper) How fast is booting into CFW? AuReiNAND currently boots in about 8 seconds. Is a hardmod needed? While no a hardmod is not needed but it highly recommended as in the event of you breaking your 3DS there is no going back unless you have your sysNAND dumped and a hardmod or are ready to get one if a brick does occur. If I brick can I used my decrypt9 sysNAND.bin backup to restore with a hardmod You should be able to, but if your dump is corrupted or something you are screwed. What happens when the console is booted without the a9lh files on an SD card? The 3DS will appear bricked. Don't worry it's not just gotta boot with the files on your SD. Can a9lh alone brick my system? Yes. If you, for example, use somebody else's OTP dump, it can and will brick your console. However, as long as you're using your own OTP dump and are using either online compilers or safea9lhinstaller, you should be fine. How easy is it to install a CFW with a9lh? For AuReiNAND it's drag and drop! Can someone provide me with a precompiled version of a9lh? If someone sent you their copy of arm9loaderhax.3dsx it'd brick your 3DS. The OTP.bin is built into the 3dsx file, and thus like the OTP, every arm9loaderhax.3dsx is unique. However, there are online compilers out there and they are even in the main guide. If you don't feel safe with online compilers there is also safea9lhinstaller. Assuming I have all the required files is installing a9lh really as easy as running a .3dsx? Yes. You boot sysNAND with a 9.2firm and run it from Browserhax or whatever entrypoint you like. No need for miniPasta or anything else. If it hangs on "Exploiting ARM9..." for more than about 20 seconds, just reboot, the exploit failed. Useful links https://github.com/Plailect/Guide/wiki to completely setup a9lh from stock. https://github.com/d0k3/OTPHelper/releases/ OTPHelper http://gbatemp.net/threads/safea9lhinstaller.419577/ Safe a9lh installer Any quick tips you can throw at me? Make sure to follow the guide closely, ask questions if you have any, and double check yourself on every step, even if you THINK you did it right. Demo of a9lh booting into ReiNAND CFW (thanks ihaveamac) Huge thanks to daxtsu for letting me ask a crap ton of question! I guess if you have more questions I can add them to the thread?
