Hi, I have a Iphone 5, IOS 8.1.2, non Apple earphones.
Has anyone successfully removed the EU volume caps?
Here's what I've tried so far.
As others have said it's quiet, especially with high ohm non apple headphones.
I used TaiG to jailbreak.
I use Ifunbox to copy files to and from PC
I use plist editor pro under Windows to edit the files.
I have a SPL/RTA audio prog on the laptop and a jack lead from iphone headphone to laptop.
Freashly restored IOS 8.1.2:
Playing white noise mp3 EU volume limit ON and calibrate the RTA software to 85db.

Full volume RTA=97.5db
EU volume limit on RTA=85db
(same files in both locations, default and N42)
deleting:
Both files in /default
Full volume RTA=97.5db
EU volume limit on RTA=85db
Changing:
Values to 1, in all or either files in both or either locations:
Full volume RTA=97.5db
Deleting and restoring:
restore original files to /default
delete both files from /N42
Full volume RTA=99db !
BUT, switching EU Volume Limit toggle crashes/restarts IOS
Stopping and starting a track causes volume to go to zero, manually turn back up.
Turn volume of to full gives high volume warning and orange bar, has to be turned up again.
I did not install Openssh or change any file permissions during this, it didn't seem to matter.
Anyone know how to get:
Full Volume to 99db and the EU Toggle switch still work?
That seems to be the max from the phone, unless anyone knows different?
Which if any of these files are in place on a US/Non EU phone?
If they are in place on US phone, contents?
I have read to restore via VPN from itunes with a US IP, does this work? Does it have any regional impact on cellular etc?
*the db values are examples, just a reference on laptop.
I also tried the instruction from Post 302 of this thread:
http://www.head-fi.org/t/682937/iphone-5c-and-5s-audio-output/300#post_10413365
The Full volume limit is now RTA=99db
With the EU volume limit toggle on the RTA=73db
Cool, I thought, maybe the EUVolumeLimit.plst number is a percentage of the slider and the top of the slider is now 1.2 as opposed to 1. When toggling the EU Limit the volume slider does indeed jump to about halfway rather then 3/4.
But, exiting settings and music apps and running them again the limits reverted to as I had them set in the previous post.
Full=97.5db
EU=85db
I'm going around in circles and getting nowhere certain.
