I was doing a nand restore using Hekate for the last dump I did before using cfw. After the restore was done my Sysnand will no longer boot up and I just get a black screen. However I can still launch my cfw using both Hekate and TegraRCMGui. To my knowledge, my nand dump was good. I was wondering if my sysnand really is bricked and if so, is there a way to restore it? Is it possible to update sysnand using daybreak on cfw?
