I've been following the 3DS guide at https://3ds.guide to update my original 3DS. I have a USA 3DS and due to Nintendo's stupid region locking rule I can't play any games from here in the UK. I'm following the guide at https://3ds.guide/installing-arm9loaderhax. I'm currently at "Section II - Installing arm9loaderhax". My firmware has been downgraded to 2.1.0-4U, but I still have the browser. However, when I enter http://2xrsa.3ds.guide in the browser, I see the message about arm11.bin loading, but nothing happens and then the 3DS crashes. Pressing select does nothing. I've went through the whole installation process two times now and nothing works. Any idea what is causing all of this? Is there another guide I can follow or a different application I can use to upgrade the firmware and get Luma3DS installed. Thanks.
