I'm in the process of installing A9LH+Luma on my n3dsxl, of course using Plailect's guide, but I've run into a problem I've never seen before. Section III of the guide says: Go to “SysNAND Options”, then “CTRNAND Transfer”, then “Auto CTRNAND Transfer” Select the 2.1.0 ctrtransfer image when prompted by pressing (A) If you do not already have a NAND backup, backup SysNAND to NANDmin.bin when prompted by pressing (A) Allow the transfer process to proceed automatically, this may take some time but that's as far as I get. Here's what it says after it fails: Step #1: .SHA verification of CTRNAND image... Checking hash from .SHA file... Failed, image corrupt or modified! Auto CTRNAND Transfer: failed! I don't know what's wrong, as I'm using the files mentioned in the guide (New 3DS or Old 3DS or 2DS 2.1.0 - USA - ctrtransfer in my case). I've installed A9LH+Luma on 4 devices before and have gone through this same procedure everytime, but I'm just now getting this error. Any idea what's wrong?
