What firmware should I be using on my E398?
I’ve seen this posted quite a few times recently, and while there’s no one perfect answer there are two specifically. Pinter’s MP or Bodyguard’s MP (get them from downloads section).
I’m sure there will be many new MP’s out soon, but for now use either of these. Both will work 100% with iTunes assuming you fix (look at the guide I did)
I would not recommend using the original 42r-for-all file as you’ll have to flex a file over the top to get english menus, and it’s missing a lot of stuff
