🧭 Which One Should You Use?

⚠️ Before Flashing: Important Precautions

  1. Unlock the bootloader – required for flashing via Fastboot. Reddit users confirm this is straightforward: “you can simply download it… unlock the bootloader… flash it then lock it back”
  2. Backup all data – flashing wipes the device completely.
  3. Choose the correct build variant – Global/EU ROMs for CPH2581; IN/US builds roll separately to other models.
  4. Use official tools – such as OnePlus’s OplusFlashTool or Fastboot commands.
  5. Re-lock bootloader after success – to maintain security.

🚀 Flashing Steps (General Overview)

  1. Download & extract the firmware zip.
  2. Install Android USB drivers and Fastboot tools on PC.
  3. Reboot your phone into Fastboot/bootloader mode.
  4. Use: fastboot flash full_flash_file.img Or use OplusFlashTool and point it to the extracted firmware folder.
  5. Reboot and then use: fastboot oem lock (or fastboot flashing lock) to re-lock the bootloader.

✅ Next Steps for You

  1. Choose your preferred firmware source (e.g., HiUnlockSupport for latest build).
  2. Download the file via the provided download link.
  3. Follow detailed flashing instructions (ensure bootloader unlocked, use correct tool).
  4. If you need help with specific steps (e.g., installing drivers, using Fastboot), feel free to ask.
