To perform this glitch you will need an armor with at least one slot and any unit that increases a base stat. First, perform the dupe glitch up until you have the bank open. Then, what you will need to do is equip your unit at the same time that you deposit the armor you've equipped. The simplest way to do this is to press Z when the bank menu is at Deposit/Take. Press A when your menu cursor is on Item Pack and your bank cursor is on Deposit. Press A when your menu cursor is on Equip and your bank cursor is on Item. Press A when your menu cursor is on your empty unit slot and your bank cursor is on the armor you have equipped. Press A when your menu cursor is on the unit you want to get stat boosts from and your bank cursor is on Yes. You will now have no armor equipped yet have a unit equipped. Quit the game and reload. Each time you quit, you permanently gain the status bonus granted by the unit you have equipped. You can now quit and reload as many times as you like until your base stats are at a value you're satisfied with. To disable the glitch, simply equip any armor or unequip the unit. As a tip, note that the analog stick only moves the bank cursor, thus you can set your menu cursor by using the pad or C-stick and then set your bank cursor using the analog stick.
