How can I find a fair price to sell it for? Do i need to remove the SIM card, do a hard reset, format the memory card? Anything else I need to do to it?
formatting the card is good--but not a complete wipe. if you're giving it to a family member--simple wipe; if you're selling it on craigslist to some stranger, you'll want to do a Secure Wipe of the card.
* Assuming you use Windows, mount the microSD card so you can view the drive (for example,"G") in Windows explorer.
* Open a command window on the computer (Start>run> cmd)
* Key in "cipher.exe /w:g:\" Remove the double quotes and replace "g" with whatever drive letter is appropriate. It means run cipher.exe in "wipe" mode on drive "g."
*this process can take up to an hour. so don't expect to do anything with the card for a little while. let it run until it's showing completed on the computer screen.
This writes random 1's&0's the card instead of just deleting information from it. just like deleting files from a computer--the information can be restored or recovered. this method of 'cypher'ing will delete & replace your information with fake data--should anyone try to recover anything.
