Activiating HD Voice on Sotmax and Orange France - Galaxy S III Q&A, Help & Troubleshooting

Hi everyone,
I searched a while without finding a way to activate WB-AMR without full wipe.
I tried many things, but i think i've found something :
This MOD is only applying to SOTMAX V12 AND ORANGE FRANCE
It is intended to help everyone finding their indivual way to HD Voice
1) my S3 is already on SOTMAX V12 (not the 3UK version)
2) i extracted /system/csc/XEF/system/csc/*.* from the Sotmax ROM V12 ZIP file
3) i modified customer.xml like this in the <Settings> :
<Settings>
<Main>
<Network>
<NbWbAmr>1</NbWbAmr>
<WbAmr>
<NetworkName>Orange F</NetworkName>
<WbAmrCodec>on</WbAmrCodec>
</WbAmr>
<NbSOSNumber>2</NbSOSNumber>
<SOSNumber>112</SOSNumber>
<SOSNumber>911</SOSNumber>
<AutoProfile>on</AutoProfile>
<AutoVoicemail>off</AutoVoicemail>
<AutoEmailAccount>off</AutoEmailAccount>
<AutoBookmark>off</AutoBookmark>
<AutoLink>off</AutoLink>
<AutoSyncML>off</AutoSyncML>
<AutoFastDormancy>off</AutoFastDormancy>
<AutoWbAmr>on</AutoWbAmr>
<AutoFOTA>off</AutoFOTA>
</Network>

4) i inserted all those files (with the one modified) in the ZIP file of the ROM at /system/csc and /system/csc/XEF/system/csc
5) i replaced the modem.bin file of the ROM with the latest one available from Orange France (see attachment View attachment I9300FTMELL1_modem.zip)
6) i flashed my modified ZIP without wiping anything
7) *#197328640# and TADAAAAA
