HMI Stock ROM Firmware

Whats HMI Stock ROM and its Advantage

The Stock ROM (Mobile OS) is the Most Stable ROM released by the device manufacturers depending on the device model and Android version. However, the Stock ROM don’t offer many customizations or features for the device.

While in general third-party firmware (Custom ROM) has system bugs and stability issues. In this case, you may experience battery issues, network issues, camera issues, missing features, lags, overheating, slow performance, and many more. But whenever you switch to Stock ROM, you can quickly fix them all.

Advantages of HMI Stock ROM

  • Unbrick the device.
  • Upgrade or downgrade Mobile OS.
  • Fix OTA update issue.
  • Fix a problem with the device startup loop.
  • Fix bugs on your phone.
  • Fix Lag or Stuttering on the device.
  • Fix battery drain issue.
  • Software performance improvement.
  • Returning a stock ROM entitles the warranty on the phone.
