I recently got a second N3DS XL, and even though I own a hacked N3DS XL, I decided to follow the guide as if I only had one console, to understand the process of installing B9S on a recent firmware (11.4) using a flashcard.
I bought a Gold RTS r4ids.cn from nds-card.com a couple of months ago and used the flashcard to hack my new N3DS. Everything worked as expected but I never realised that one could backup the flashcard's own firmware using a hacked N3DS.
After installing B9S, I had to look for a firmware backup for my flashcard and I used the one provided in this thread because it was easier to identify my card here than in the 3DS Guide. The firmware works as expected, but I am pretty sure that my flashcard now uses a different icon than the one it used to show. Could it be a different firmware version? Is there a way to know what the firmware version of my flashcard is?
