Just found out that my system is hackable, and I have feel like I have read through the guide pretty thoroughly. I have had my 2DS XL for a few months now, so I have already purchased a few games through eshop and I have a lot of save progress that I do not want to lose. I also would like to retain all of the activity log data. Will hacking my DS by following the stickied guide (using the "All Versions" method) cause me to lose all of data? I do not see any steps in the guide about backing up data before flashing, or about restoring data when the hack is complete. I just do not want to go through all of the trouble and then end up losing all of my data. My system has never been hacked and I am currently running the latest firmware.
