Followed this guide https://github.com/Plailect/Guide/wiki/Region-Changing to change region from EUR to JAP and bricked, did everything it said apart from I think I deleted too many titles in FBI since I didn't know how many titles I had to delete with previous Product COde. Have A9LH and 10.7 backup (which I'm flashing back) but really wanna change my region.. I'm confused as to exactly which titles I should delete in the FBI step.
