Hmm, thanks for the info. I'm already on 11.6 but maybe I'll do this eventually. I don't really have the time to downgrade and backup all my data and such right now, but it's nice to know it's possible."Do It At Your Own Risk!"
I just found a way to update my Sysnand N3ds 11.4 USA to 11.6 USA without breaking the backlight control on NTR! And what's more is I can play online now
(Assuming your on 11.4 and below, If you already updated your system to 11.6, Welp there's nothing we can do about it unless you know how to downgrade your N3ds...)
First of all, I made a NAND BACKUP On my N3ds in case something goes wrong.
(Read all of the guides further below before going to the links!)
Next is I went here : https://yls8.mtheall.com/ninupdates/titlelist.php?date=09-18-17_08-00-44&sys=ktr
(For O3ds, I think it's here: https://yls8.mtheall.com/ninupdates/titlelist.php?date=09-18-17_08-00-39&sys=ctr)
Then I looked for all of the updated title IDs of 11.6 (USA Which is the region of my N3ds),
I used My N3ds and FBI and went to "Tickets", then I searched the title IDs(USA)
Then I installed them from CDN(I pressed [A] For DEFAULT VERSION):
(Make sure your N3ds is connected to the internet)
here are the (unnecessary) ones I didn't installed:
1.USA Error Strings
2.mint (eShop applet)
3.Web Browser Data
And here are the ones I installed and updated:
1.CVer
2.friends system-module
3.NS system-module
4.NEW3DS NVer
After done installed, I powered off my N3ds and boot it up again and went to friends list and I'm online!
Then i went to System Settings and I saw I'm on 11.6 USA!
After that, I went to bootntr selector 2.9 and run the 3.6 of it and open the NTR menu and I can see and use the backlight control
And I tried playing games online to see if it's really working and it works!
Hope this Guide helps ty.
What would be really nice is if we could just get a new update to fix it, but I realise it's not a priority nor typically something easily done.
