Hi' You will need to flash the custom ROM/firmware in order to remove the previous Google account. You can download the ROM/firmware here: http://roms.satechhelp.co.za/product/mobicel-vivo/ at R20 airtime donation, download SP Tool (software to use for flashing) and then download and install the MediaTek Preloader USB VCOM. You will need a computer to perform this task, If you do not have access to a computer please go here http://www.satechhelp.co.za/software-reloading
