  • Make sure the device is rooted before going forward for custom ROM installation
  • Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing TWRP in the smartphone.
  • Make sure to install USB drivers on the PC, or else your smartphone (Xiaomi Mi 4W/ Mi 4 LTE/Mi3W) will not be recognized by the computer.
  • Make sure the device has more than 80 percent battery, or else there is a chance for smartphone getting temporarily bricked if the installation process is interrupted mid-way.
  • If you face force close, go to Settings >> Setupwizard >> Give permission
