How to Downgrade ASUS ZenFone 2 Firmware


Yesterday ASUS gave us recent update in ZenFone 2 ZE551ML 2.20.40.156 and ZenFone 2 ZE550ML 2.20.40.135. Personally I don't like this update because Now I can't use third party Themes, which you must download from Theme Store for free/paid themes from ZenUI designer and I don't see any good themes except Speed Themes :). This tutorial is applicable for Downgrading Firmware or even back to stock rom. Please do it carefully and DWYOR (Do it with your own risk) because wrong move may cause the device brick :)

  2. ZenFone 2 Original Recovery.img, bootloader.img, boot.img (ZE551ML | ZE550ML)
