I had nexus 4 for about a year. Had so much personal data, apps,chats, pictures etc. Device is stolen 2 days ago. Is it possible for the thief to access my data? My device was rooted and with unlocked bootloader with custom recovery installed and screen is locked with pin. I am not sure about flashing factory image will wipe data knowing that the bootloader is unlocked? Or Will flashing will just replace the system files only? So much confused and tensed about it. I already used android device manager to erease all data but not feeling secure.
