Ok, I bit the bullet and went along with the system update, and it stayed on the current firmware *whheew* so now I just redownload all the games I had before? Or is there a program that redownloads all your old tickets for you?
On a positive note, Thanks to Tomodachi life I'm able to restore all my precious Miis
love it when things come up Milhouse after a rough day
I thought Tikshop does exactly that? Download your old tickets that is. I've never used it but that's pretty much the description of the software. If you already have the games on your SD card, and have installed the tickets with Tikshop they should work as is.
You should also remember that there is literally 0% chance for Nintendo to roll out an update in which they remove A9LH because of the way it's installed. A9LH protects itself and persists through updates, but if Nintendo was to find a way to remove that protection they stil wouldn't be able to do anything because simply patching it would cause a brick and not only for A9LH users but normal users too. Not obviously something Nintendo can do, so they can't do anything. As such, if there's an system update .. Just update. You might as well. If you're worried - Update your Luma3DS before updating the console just in case. And if all else fails, you can always restore your backup which you surely have. Given this thread you don't actually have a backup (or didn't).. Did you create one? If not, boot into H9 by holding Start when powering on the device, and make one now, then back it up to several locations. You never know ..
Lastly, you can check on Nintendo's site for System Software Update History, by doing that you can clearly see that 11.2 is the latest update they rolled out. Your update most likely fixed something that was broken, such as Health and Safety app if you didn't inject hs.app back into it.
