I have a R4i RTS 3DS (www.r4ids.cn) which has now the 6.2.0 update from said website. The 3DS itself is a large one with 6.3.0-12 on it. According to the said website the 6.2.0 update should work on the 6.3.0 fw but it doesn't. It just goes straight to black screen with 'please power off' etc... Any ideas? Yes I've updated to 6.2.0 for the flashcart. Yes I've updated to the latest kernel 1.62. Thanks.
