Re: can i retrieve deleted text messages from my lg optimus elite phone?
Technically yes. Practically no.
They're in a database file. You have to open that file with a SQLite editor, find the deleted records (they're still there if the database hasn't been compacted, they're just marked deleted) and update those records to be not deleted. So unless the phone is rooted and you understand SQL, you probably can't, even assuming you could find the right database file.
That's what apps like
SMS Backup & Restore are for.
