Recently I updated from 1.2 to 2.1. The entire process was fairly smooth. After I finished updating, I used the Format EMUNAND option. I rebooted my Gateway and made sure that I was able to enter the EMUNAND. I shall now describe the precise things I've done which led me to the error. 1. While in EMUNAND, I went to System Settings and selected DS Profile again. This led to a black screen error (shown on bottom screen) that required me to power off manually. 2. After I restarted, I wanted to differentiate the EMUNAND from system NAND by changing the system NAND's display language. I changed the display language from English to Italian. 3. I tried to enter Gateway mode. I didn't even get to see the new Omega logo before I was booted to the main menu with an error stating that "An error has occurred forcing the software to close the system will now restart" (initially this was in Italian). The 3DS accordingly restarted. 4. I tried changing the language back to English. However, that didn't stop the error from showing. 5. I tried entering Gateway UI by holding down L trigger. The same error appeared. 6. I tried formatting the SD card and putting a fresh 2.1 launcher.dat onto it. The same error appeared. 7. I tried using the blue card again. Upon launching the exploit app, the black screen error occurred prompting me to turn off the system. Did I somehow break my system, or is there some obvious solution to my situation? Thanks in advance. I have a backup of the system NAND and all content on the SD card pre-update available.
