Wait, are you looking for flashcart (like R4, acekard, EDGE, etc), or an SDHC adapter? if you’re looking for flashcart, i recommend R4 (buy it here r4i-sdhc.com) or maybe acekard 2, whatever fits your budget. make sure you buy the newest one, as some flashcard might not be reproduced again and the software is obsolete
use the guideline provided by iFixit to dissassembly ithe DSi and check for all the cables for corrosion or maybe seated improperly. make sure the screens ribbon cables are fine too, since it is the common cause of dead DSi
When i changed my housing and reassembling, the DSi won’t turn on
trace back the problems and it ended up in this battery board (i change it with another battery board and it was okay)
my question is: what prevents my DSi from turning on? i checked all the ribbon cables and the battery cable below and everything was fine
i need it for my 2nd DSi, thanks in advance
