Jayadevan, Jun 12, 2017 : I decided to switch from CyanogenMod to LineageOS. I synced google contacts and also took a backup of my Oneplus One using rsync to my Ubuntu laptop (all folders,files). I then used TWRP to really clean everything on my OnePlus (wiped everything). I installed LineageOS without issues. But when I synced contacts, I realised that many contacts are missing. Is there a way I can recover them from the rsync backup I took?
