memory problem
 

my 1 Gb Mp4 player (lg s1 mp3 player v 3.5.37), memory just became to 232 mb only, due to formating , and partitioning and due to using mp3 player disk tool, now how can i get recover my 1 gb again .....

You can't, because there never was 1GB. You were mis-sold an item. IMHO - complain to whoever sold it to you, and anyone else involved in the transaction - PayPal, your credit card company etc. And let us know who was the douchebag that sold you the player.

Sorry to hear it, dude.

rjsoni21 , as Strummin'Ronin mentioned, there isin't a 1GB memory chip installed, likely it would be a 256MB chip.
To verify further, you can open your player and check for the memory chip's serial number.
