Just buy an older model than you have , easiest is with a nor chip not a nand, I followed librasevens youtube video

most of the older models are easy to jb especially if you can get one thats never been used. Like shawnf1986 said, ones with nor chops are easier to downgrade if that ends up being what you have to do
