Repack US to EU game and update it

Hi guys,

I used the repack method described here : https://gbatemp.net/threads/a-complete-rednand-guide.446878/

My constat :
- works fine with game who dont have any update available (i only tried to repack US content to EU)
- dont work with game update (even you repack also the game update with this method)

With an updated game (normal or repacked update), he just wont boot or freeze.

My solution (used with Olli Olli US) :

1- Download Olli Olli US with his ticket...
