@roms or any other person.
A noob did factory reset, but before that, he connected phone to computer and copied all phone files and folders to computer in a separate folder.
Any way to get contacts back?.
I was able to get many contacts from gmail contacts and sync, but not all.
Any way to get back all contacts from the files he copied?.
E.g. Transfering some old contacts files or folders (previously copied from phone before factory reset) via file Explorer to phone.
The phone (S3 GT-I9300) is working good and has root access.
Updates
Found an old contacts.vcf file from backup data and restored all contacts.
The above thing is not possible, as copying data normally does not copy root folders to computer.
