This is my first how to here so I know it will sucks but oh well lol.

I saw someone post on general forums about voice quality. For what reason this isn't set to default i don't know.

What this does is enables and changes your Voice codec(unless its called something else) to EVRC-B.

Requirements: Need your MSL #

To get your MSL # you can either call sprint and play dumb(I say i need to reprogram my phone) or since we have root download MSL Reader off the market.

Step 1: Once you have the MSL # go to you dial pad and press ##3282#.
Step 2: You will get a window that says EPST, hit the Edit Mode. This will prompt you for your password. Type in your MSL number there and hit OK.
Step 3: Now your are in the EPST, Go to the Advanced menu.
Step 4: Scroll down till you see Vocoder. Enable this if it not by pressing on it and slecting enable.
Step 5: Below Vocoder is the EVRC-B, do the same thing if it is not enabled.
Step 6:Next setting is the Home Orig and Roam Orig. You want to change these to EVRC-B.
Step 7: Press your menu button, Commit Modifications will appear. Press it to save the changes. This will automatically reboot your phone.

Once it is back up, people should notice a better call quality from you.




Written pretty ****ty huh? lol

I've heard not all of the towers use all of the codecs.. but I'd think that wouldn't be a problem unless roaming or in rural areas.

I did this on my EVO 4G... I don't think it made any difference whatsoever.

Tried this on Synergy's latest nightly. It didn't automatically reboot the phone, but I lost signal completely. I'm manually rebooting now, I'm praying that it works properly.

What are the default values, in case I need to change it back?

Have tried this before and completely lost signal. YMMV.

I am trying to figure out the completely unnecessary use of profanity at the end of your post though. Try to have some class when posting in a forum read by all age groups. Read the Forum Rules regarding use of language which may be offensive to others.

I ended up booting just fine, got my signal back as well. I guess Synergy just wasn't interested in getting rebooted :P

I'll see if it works, it's about 4 in the morning for me, so I can't really call anyone.
