i haven't update my sons cards (r4gold.cn non 3ds) since the summer, it was running wood 1.47 fine.... yesterday i download a couple of new games that wasn't supported by the old wood , so i patch the card with the latest patch just in case because i don't need it, and download the latest wood, everything went fine, i even patch the card with the new wood firmware 1.56... but when i try to load any game it got stuck on the loading screen... the firmware runs fine, i can change all the settings, the themes and options, it can even run the patch... it just wont play any ROM with wood 1.56, it just play Roms with wood 1.48 or below. i test it also on an unpatch r4gold.cn (non 3ds) and the same thing happens...
i have 4 r4gold and all behave the same... patched or unpatched...
PS yes, the TFs where formatted, the roms where clean roms and previously played, and the cards are 100% genuine...
