Infinix Hot 4 (X557) gets Android 7 (Nougat) update, here’s how you can update yours using Tcard or SP Flash Tool

The Infinix Hot 4 (X557) has received an Android 7.0 (Nougat) update. If you wish to update your Hot 4 from Marshmallow (Android 6) to Nougat (Android 7) then here’s a checklist before you go ahead:

  1. Check your phone’s current Build Number under Settings > About > Build Number and write it somewhere safe; you might need it later
  2. If you have rooted your Infinix Hot 4 then ensure to unroot your Infinix Hot 4 because installing an OTA update zip on a rooted phone could brick it. This however doesn’t apply if you’re updating via SP Flash Tool
  3. If your Infinix Hot 4 is running on a custom recovery then ensure to flash back the stock recovery
  4. If you can’t find the Infinix Hot 4 firmware for your Build Number then it would be wise to dump your firmware in scatter format using Miracle Box so you can easily rollback to your previous firmware / build incase the update is buggy or not fully compatible with your build
