Motorola V551 / V330 / V547 / V555 / V557

I have had my cell phone for 1.5 years and the ear speaker volume was slowly getting lower until I could not hear anymore and had to swithc to a bluetooth headset but I finally found a fix for the earpiece speaker for the mobile Motorola V551 which I think will work with other Motorola v500 models? I tried the fix and it works well:
