I have a EU 3ds with fw 18.104.22.168E and a EU 3DS XL with 22.214.171.124E, but on ninjhax web page the last digit for 4.X FW starts from 7. I tryed other QR codes but none worked for my 3DSs. I wrote to Smealum reporting this, but yet no answer. AFAIK the last two digit can be only update online, with game card I own I can update only the first two to 4.5 Someone had the same problem and solved it? Is there any way to update offline the firmware to a version 4.5.0-7E?
