I want to set my samsung sph-m510 back to factory settings how do i do it?

you may check the antena cnnections,or check if it has got a serial #'because if you unlock with a wrong code it deletes imei and you wont have network,take it to an expert for imei settings that is if youstill have the imei sticker under the battery cover

You can download the manual from the manufacturer at:

Please leave feedback if you find this helpful. Thanks.

That file has to be in the same folder as your other ringtones are for it to be accessed. Get it in there and it will work.

my samsung shows half white screen,top half plus freezes on certain screen & shows static.Can u tell me whats wrong with it as im not sure if its a battery error or malfunction??

First of all, allow the phone to completely dry by removing the battery and sim card, and placing it in a warm (not too hot) location for 24 hrs. (do this ASAP)
If you're positive your phone is dry, go to settings > phone profiles, and select the 'normal' profile.
This should put your phone back into 'normal' mode. However, there is a chance the radio circuit got fried... (which means getting a new phone)
