EU volume limit cap removal

1 – first jailbreak

2.2 – Take on your computer “ RegionalVolumeLimits.plist” and make a copie.
2.3 – Open the file with a soft like Plistedit pro (freeware)
on mac  :
there is a same soft on windows, but i have not tried it.

2.4 – Change all value : <real>0.82999999999999996</real>  to <real>1</real>  (write 1,00000000000000000)
2.5 – save and replace on iphone the file
