Ringger bug troubleshooting-
First off, I have never had the ringtone bug ever from Mighty 4.6 through R3BORN. Never had to convert files, I use BT, and most other common apps.
For those that is having the ringtone bug what "shipped" ROM are you flashing with to prep your phone:
1. Original RUU_VICTOR_C_SPRINT_WWE_PPST_1.09.651.5_Radio_1.00 .00F_NV_1.44_Ship
or
2. Maintenance Release
HTC Touch Diamond MR 2.00.651.7? This is the one I always pre-flash with.
One thing that might be of interest is the fact that I always use the "Ring-WindowsMobile" ringtone. This is one of the ringtones that exist in
\Windows\, but not in
\Windows\Rings- not sure if this makes a diffence in any way.
Just thought I'd contribute to help the guys with this issue.
