Miss named my tethringprovision.odex

Hi
I have at&t samsung s4 i337. I was trying to make it tetherable after rooting but un fortunaitly
When I was giving name to tetheringprovision.apk files than as I have to name thetethringprovision.bak and tethringprovision.bak2 I mistakenly give them the same name now I have missed one file and there is only one file now what shoul I do ?
I have copied new apk file and make it reboot but its was hanged on setting
Than I make it reset and again it is not working and that tetheringprovision file is only one that existed.

Please help me that I recover my previous apk and odex file so that I could make again this process very well?????
