So I know it's been a long time now but I've only now gotten around to doing this. I checked and I did install B9S and I attempted to reinstall only to be stopped by the fact that I can't actually power on my 3DS. I can't exactly recall what version Luma or B9S I had but if anyone knows how to check only using the system files then I'll be glad to look. As far as I'm concerned, I'd just like to boot up the system to transfer my saves to a new system as I already had a broken top screen anyway so I'll just be getting another 3DS anyways. Here's a better retelling of what happened as far as I can remember:
I was trying to play Animal Crossing online when I noticed I needed an firmware update to go online. I check on Google to see if it's safe to update as I didn't want to just do a system update and accidentally brick my system if I needed to do something else before updating. I check online and I see somewhere that I should just use Luma Updater to update Luma and then update my firmware. I go to update Luma using the Luma Updater and I believe I selected the latest stable build to update to and when the system attempts to restart, it doesn't. The LED Power Indicator lights up blue for a second then disappears and the system doesn't power on. I believe I was running firmware 11.5.0-38U and required an update to 11.6.0-39U.
I'll be trying to keep an eye out on this thread frequently now so any and all help is very much appreciated and I'll be happy to answer any questions to help solve this issue.
