Unfortunately I bought the 2DS "as is", and it didn't have a OTP file or NAND backup. But, as long as I wont ever need those files, I don't mind.The OTP you have if you've installed A9LH, and it's in your files9 folder. You can't get another without downgrading to 2.1. You won't need one for anything anyways, because if you could install A9LH by flashing an image onto your console which is what udsploit and safehax does, and for some reason you had A9LH uninstalled, then you could just use the NAND image you'll create shortly.
