Hello guys! I recently managed to change my O3DS LL (Jap) 9.4J emuNAND to 9.5U. I followed the following steps (from this guide): 1. Installing rxTool, Booted into its menu, then chose generate fat16.xorpad option. 2. Downloaded 9.5 firmware using 3DSNUS, deleted all the .cias starting with 0004001B, 0004800F, 00048005, 00040130 and 00040138. Actually I used a script to do that. I really have no idea why do I have to do this. 2. Booted into emuNAND, opened dev menu, installed all the remaining cia for the firmware. 3. After the install successfully done, I turned off the 3DS, took out the card, extracted emuNAND using emuNAND tool 1.0.3 4. Using Secure infor tool, I injected a public secure infor US into my emuNAND, along with that fat16.xorpad generated before from the LL console. 5. Reinjected that emuNAND into SD, booted up console > saw duplicate icons, put them all into a folder but not deleting them. But the problem is that 9.5U swapped firmware on my LL is so unstable that it freeze every time I open an application such as Game notes, Notifications, browser,... then get back to home menu. Even cia games in US region freeze opening up. Is there any step taken above wrong? Or its just it is not 100% stable at the time?
