Okay, so I think I found a bug.
I was deleting some files with GodMode9 (0.2.0), then I dismounted the SD card, put some files on it, and put it back in.
Then I opened the payloads folder in the aurei folder (godmode9 is x.bin), and renamed default.bin (decrypt9) to d.bin (I wanted to rename it to y.bin, but it was already existing), then renamed y.bin (linux loader) to select.bin, and then renamed d.bin to y.bin.
But apparently, there was a problem because d.bin had been renamed to y.bint.bin.
So I tried to rename it again (I removed the .bint), and it was renamed... to ybint.binn. I tried again and removed only one character (the first b) and it removed the character. But the file was now named yint.binnn. I removed the first n, and the file was renamed to yit.binnnn.
Then I made a video to show the bug.
And now, GodMode9 refuses to start. Like if it was not detected by AuReiNand.
Here's the video :
