I cant hear in comming calls, it flashs and goes to recording but no sound. Anyone know why ?

Phone is in silent mode. Check your owners manual or user guide for how to change out of silent mode. Try turning up the volume at the main screen, this works for Samsung phones :)

Sanyo MM-8300: ALL the keypads are frozen and won't work. Any solutions?

One thing you could test for is a thermal-fault in the phone's circuitry. To do this, you put your phone in the fridge over-night then, turn it on the next day and try the keypads while it's still cold from the fridge. If that doesn't help and you're brave enough to venture into the inner-workings of your phone to attempt repair/cleaning, you can read my post here- keys won't work on sanyo mm 8300 phone.
Hope this helps, TechnoWolfy.

Keys will not work

Sounds like you locked the keypad.

I know you stated all the keys don't work, but let's give this a try.

Press the "unlock" key (the key in the upper left)

Enter your lock code (usually 0000)

Let me know if this helps.

I am soo sorry for you. You have locked your phone and forgotten the code. Not a good thing, sprint and all cellphone companies have regulations meaning that password cannot be retrieved ever. There is no way to access that information so you will need to either go in or call in and get your phone hard reset. You will lose everything but you will have access to your phone again. I am sorry for you but remember the lock code in the future or don't lock it at all. Hope that helps :)

Recovery mode / serial data displayed ! keypad inop ????

If you have a cable for connecting it to your computer, you might be able to get it working again. Otherwise, I'd suggest removing the battery and putting the phone and the battery (separate) in the fridge over-night. The next day, insert the battery and turn the phone on to see what happens. If it's still stuck in recovery mode, I'd advise seeking help at your local phone store or sending an email to sanyo asking for any codes they could supply.
Hope this helps, TechnoWolfy.
