there you go, its because the modified firmware is named as like a higher firmware than 3.55, basically you will need to downgrade once more to something lower than 3.41 by doing the same downgrading steps but instead of using the modified 3.41 pup u will use any other firmware PUP below 3.41 my tut shows 3.15 but you can probably use 3.40 if you want
