A friend of mine recently re-discovered his O3DS brought in 2011, and the system version is 2.1.0-4U. I tried to persuade him of getting OTP first but he just want an emunand on it. Nah. So here's my problem. Is there any method to enter HBL via this 2.1 system? I noticed that browserhax has a version which support this version but missing a loader, which makes it cannot launch any homebrew in the 3DSX format.
