need of Oppo Find X PAFM00 OFP file extract / unpack

I'm looking a stock rom which is already extracted/unpack from OFP file. trying to reset my phone which is the previous owner did not unlink the oppo id unit, when i try to reset the data and reformat in the recovery, its asking the password and can't continue to install the apps. i try to update in the recovery but still i can't coninue. also can't contact the previous owner, the contact number that he gave me.. its a boogey.
