Thank you for the instructions. Fixed my daughters 3ds. Disassembling is very easy, I had no problem with the screws using a 00 Philips. The SD Cardreader was very tight glued to the metal shield underneath, so it bend up a little bid. Reassembling has hard-earned its “very difficult” rank. Reconnecting all these very short ribbon cables to the microscopic ZIF ports is a !&&*! A youtube video about fully reassemble a 3ds and a roll of adhesive tape helped me at the end.
