So I have an Asus zenfone 5z and I would like to unlock its bootloader. In theory, I would only have to download asus unlock tool from here: "https://www.asus.com/br/supportonly/zenfone 5z (zs620kl)/helpdesk_download/". However, the server that used to support the app hasn´t been online for years and there is no alternative as the device doesn´t have an OEM unlock option. Can someone help?
