Hi there, long time reader, first time poster (or almost) Seems I have a problem upgrading emunand on a 3DS, let me explain: Had a 5.1 3DS, no gateway or compatible DS flashcard (gateway is on the way, that's why I want to "prepare" this console) ✓ Downgraded to 4.5 using the browser exploit + gateway 3.03 launcher.dat + gateway.dg for my region (EU) ✓ Return to gateway launcher, format EmuNAND ✓ Boot EmuNAND (classic mode, as I have no gateway flashcard right now), confirmed I'm on GW3D 4.5 ✓ Format system while in EmuNAND (this is to have a different ID than my NAND for eshop etc...) ✓ Reconfigure system (time/date/nick/network ...) in EmuNAND ✓ Update system while in EmuNAND --> takes a while and tells me the upgrade has succeeded and ask to reboot ✓ Reboot (in SysNAND) and access the gateway menu via web browser exploit X Boot classic mode -->> BSOD, then I can only reboot to SysNAND obviously. I've tried many times, with 2 different SD Card, the 2GB that came with the 3DS, and a 32GB, no success, I can't boot into Classic mode after EmuNAND upgrade. Isn't 3.03 supposed to be compatible with 9.4 EmuNAND ? Or maybe I missed something else, I've read a lot, but I'm pretty new at 3DS tinkering. Thanks ! edit: OK, I found the reason, you can't boot into EmuNAND 8.x or higher without a gateway red card in the slot, hence it doesn't work after upgrade.
