This goes not only to those who are new to the scene. This is for everybody who doesn't have a NAND backup yet. Ever since the free userland exploit has been released and now combined with the arm9 exploit, everybody can now get their hands on things that may cause brick. Now in the past few days, brick rate has increased significantly. Worst part is, the most important thing to do when doing sensitive stuff is often forgotten and/or overlooked. Now to the people who already know their way around, please make a NAND backup if you still don't have one. To those who just started looking around but has few knowledge already, these are some tools that can be used to make a backup: decrypt9 & hourglass9. Now to the ones who doesn't have any clue about this but want to dive in with arm9loaderhax installation, be sure to follow this, and only this GUIDE. No videos, no other site. Just that guide. Lastly, to those who bricked without having a NAND backup, let this be a lesson to you. Creating a NAND backup should be Standard Operating Procedure before doing anything risky. That's all, happy modding everyone. Stay safe --- always have a backup.
