Tricks To Enable HD Voice on SGS2 - Galaxy S II Android Development

Hey Ppl
The most people know it´s impossible to change WB ARM status (On/Off), on the Service menu (*#*#197328640#*#*) with ICS and JB.
But this are possible in GB.
But i´ve found a little trick to Enable WB ARM (HD Voice) on SGS2 with ICS or JB.
1. First you should download this file to your mobile, i have attached (Modem LPB and Modem LQ6)
2. Go to recovery menu and first flash LPB.
3. Reboot the phone, and enter this code *#*#197328640#*#*, Go to (7) "WB Arm Status" --> WB AMR Enable (Check the status is On)
4. Now reboot again to recovery menu, and flash LQ6 and reebot.
Now you have HD Voice activeted on SGS2

Hi,
And do you hear any sound improuvement ?
Thx

Hi,
Am too interested in knowing that does voice quality improve ?? Also does the OP has any idea of how to enable Audio ? This is disabled in S2 ICS Stock.
Also I read in this forum that the settings made in service mode are temp and once the phone reboots the settings are reverted to default is it true ? if so how to make it permanent ?
Regards.

Yes there is a big difference, but there are some requirements:
1. Both partners phones should support HD Voice
2. Your Tele Company should support the HD Voice
3. Both partners need to be on 3G networks (2G and GSM does not work)

Since LPB and LQ6 are Android 4.0.4 modems and your on 4.1.2 that's the reason you cannot flash them. You will need to install a ICS/JB 4.0.4/4.1 Samsung ROM in order to mentioned in the OP.
AOKP ROMs service menu does not work!

Hi, thanks for answer.
And then that means that on SGS2 with Jelly bean is not possible... I don;t know why, because the SGS2 and SGS3 are HD voice compatible and with the same operator (Orange) only the SGS3 have hd voice active.

Its working on my 4.0.4 LPT stock ROM.
Flash the LPB modem, change the setting to "on" and then re-flash my favorite XXLPX and its there.
edit: reboot and it remain "on"
