What is the procedure to take a case back filed earlier

Hi I wanted to know exactly how many days and how much money would be required to get the person out of jail,convicted under ipc 379/411 . Brief about the case: A phone was taken away from office because of utter frustration and anger of seviour salary pain as not paid for more than two months.However the accused returned the phone on next day by himself while self realizing that it was not the right thing/shameful act because others property. Though the phone owner accepted appology as colleague at work, but Police got involved and FIR /case filed under 379/411 ipc and sent to jail. So please be advised as how this case could be closed before chargesheet filed.and if possible ,be advised how much fee would be required(maximum) to finish the case.Please be reasonable
