    My Samsung Sprint M300 keeps powering on the goes to the main screen then powers on over and over again. I can't receive call but I can make call only if I do them fast when the main screen comes on.

I received Samsung M300 from Sprint back in July 2008 as a "freebie". I observed exactly the same behavior **out of the box**. Did not drop it and did not get it wet. Since it was sent to me by a Sprint phone solicitation, the local Sprint store had no interest in the problem (no swap out). I suspect these "freebies" are actually refurbished phones, but I have no proof.

I tried battery replacement (with known good, fully charged battery), cleaning battery contacts and patiently pressing the END/(!) button repeatedly to try to power on the phone.

My next step may be to take it back to the Sprint store and have them "test" the phone (rather than pushing for a replacement). Maybe that would lure them into doing something if they see it as a potential "add a phone" scenario! :)

You problably dropped the phone, or got it wet. Thus short circuiting either the motherboard or the battery.

I am trying to pair a bluetooth em227 to a samsung sph-m300 but it asks for a input pin? I have tried 0000,000000,1234,123456,9999,999999,1111,111111,and my phone number...not sure what else to do?

You must put you headset in pairing mode, prior to trying to pair it with your phone. In order to do it, starting with it turned off, press and hold the power button for some 10 seconds, until the indicator light is alternately flashing in red and blue. It is in pairing mode now. Then, bring your phone close to it, and make its bluetooth application search for new devices. After a little while, your headset should appear on-screen. Select it and make it connect. If a pairing code (or passkey, or PIN) is requested, enter '0000' (four zeros). If the pairing process is successful, your headset should enter the stand-by mode (blue light flashing every few seconds). By the way, If its user guide happens to be missing, or, rather, you need further informations on how to pair it with your phone, feel free to download it from this location.

Phone stuck on Camera

The phone has frozen. you may need to reset the software to get it running again. But you might loose your data if you flash the phone. I hope you don't have a problem with the screen. sometimes too, when the memory space is filled up, it freezes up. Take out the battery for some hours and try again. if it does not resume, then you may have to flash the phone to reset it to factory setting. Cheers!

2630 master reset code

remove the sim first. then turn the phone on. Then type *2767*3355#. It should start resetting. Then power off. Put the sim back then power on. If the code is wrong try *2767*8355# but i'm sure the first code *2767*3355# is correct. good luck.
