Thanks to all who answered, now I juts need to find out why browserhax aren't working. I have tried 30+ times, and the browser just crashes every time.
Delete menuhax and have it download a new payload. The payload it used while you are on 10.3 will not work now that you are on 9.2
Ok, well then I guess that's solved, but there's before I can download a new payload, I still need to access HBL.
the latest version of HBL probably only works for 10.3,
I have searched around, and there seem to be many others who have successfully finished it, which means that most likely I just did something wrong, and that HBL opens in 9.2.
Keep trying with brownserhax until it boots. I usually have a bigger success rate trying to run ctrbootmanager over it and then selecting hbl from it. However booting homebrew launcher through brownser have always been a bit unstable.
Homemenuhax won't work until you install the proper 9.2 payloads if you're still using the 10.3 ones, and afaik Ironfall is not compatible with any 3DS version lower than 9.5
I guess that's why Ironfall won't open, but I've tried to use the QR code 30+ times, to no avail.
Format SysNAND and re-install MenuHax?
I'm pretty sure to format SysNand I'd have to access HBL, but maybe not. If there's another way, please tell me.
To get Browserhax to work on 9.2
1-Scan the QR code at BH's main page, it should lead you to the slider hax page
2- to run the hack , simply touch the right-most part of the slider
If that didn't work
Starting from step 2:
1- at the same time that you touch the right-most part of the slider HIT THE "A" BUTTON
^that worked for me 2/4 of the times , the just erase your old menuhax and install It again to get the new payloads
I've done this, I also tried holding A (just realised maybe it's cause i held A, instead of hitting it, but probably not), and it didn't make any difference.
If anyone else has something which might help me, I would be very thankful.
