i'm not sure. I downgraded my sister's 10.3 O3DS by setting up menuhax through browser hax literally right before i did that one so the difference might just be the firmware.
So I'm trying to downgrade my cousins O3DS XL which he hasnt used much and is on 10.1 and everytime i try to use the browser it prompts me to update the system. With 10.4 out just wondering what i should do or if i have to wait.
im on reinand and used mini pasta to get to fgbi to install the agb to the NAND and the the games to the SD, and then i did the same process on my emunand via fbi.
What cfw are you using to get gbavc working. Im on rei 3.1 currently and installed the patched abg to the NAND via mini-pasta along with the games and get an error when i run it in emuNAND
EDIT: got it working
just tried it. Installed the arg firm and games via mini pasta through fbi, then installed again on emunand 10.4 via fbi. Still no luck. :\ My pokemon Red version worked but none of the gba games
