Stuck with a Hot fix that I installed from one plus download

Hey Everybody

I recently had an issue with my fingerprint reader, thought that there is a hotfix for that and installed on my phone by copying zip file onto my phone. Then recognized that the hot fix is not supposed to be for INDIA and it is for Austria or somewhere. I am not able to boot my phone, can I remove the hot fix and revert to its original state.... Urgently need your help
