🧭 Which File Should You Use?

Decide based on your region and target OxygenOS version:

  • For stable OxygenOS 14 (India) → use 11_14.x.xxxEX01.
  • To upgrade to 15.x (India) → look for 11_15.x.xxxEX01 or 15.0.0.xxxEX01.
  • If you’re in EU/Global, you may prefer flashing CPH2581 instead.

  1. Backup all data (flashing erases everything).
  2. Download the correct ROM package + flash tool + drivers.
  3. Install USB drivers in Windows.
  4. Power off phone and boot into EDL by holding Vol+ + Vol– while plugging into PC.

  • Choose firmware matching CPH2573 (not CPH2581/2583).
  • RC or beta builds—like OxygenOS 15—might lack full OTA or stable support.

  • If targeting EU/Global region, CPH2581 may be better; but note unlocking or region-swapping may complicate future updates .
