I updated my 3DS to the version 3.0U. I was ok cuz I have a DSiXL in 1.42 and my bro has another 3DS that hasn't been updated. Ok so I downloaded the firmware update that support 3DS3.0 and DSi1.4.3. from the Acekard website. I copied ak2ifw_update_3ds30_DSi143_onDSi_and_DSXL_and 3DS.nds and ak2ifw_update_3ds30_DSi143_onDSL.nds on the root of the microSD and tried to update on my DSiXL but when I boot the update(My Acekard is HW88 before you ask) it says 'Update cancelled' or something like that even before I pressed any button. So I was "Ok I might did something wrong" and tried it again but with the same result. Tried it on my bro 3DS but with the exactly same result. Tried the update for the DS but when I pressed the 'B' button nothing happened. Every other update has worked without any problem. Can someone help me? Thanks in Advance!
