i did change my vocoder settings and now my phone is nice and loud. the thing is getting sprint to give you ur MSL but within the thread there is a link to XDA that explains how to get your MSL without sprint but using CDMA workshop...thats what i did.
Does tech support ask why you need that information? If so what's a good excuse? Does this change ALL volumes or just in call volumes?
Tell them you reset your phone and cant make calls and you need them to walk you through reprovisioning your phone. They will have you edit your MSID which requires them to give you your msl code to enter in. Write it down.
