Flashing a Custom ROM

Step-by-step guide to flashing a custom ROM on the OnePlus Nord CE 3 5G (ziti) — recovery, format data and adb sideload.

Warning

Do this at your own risk. No one is responsible if anything happens to your device.

Files required

  1. Custom ROM .zip
  2. ADB platform tools and drivers installed on the PC, with a bootloader-unlocked device connected via USB cable
  3. Recovery .zip (provided in the ROM's post)

Steps

  1. Extract recovery.zip and copy its contents inside the Platform Tools folder.

  2. Reboot the device to the bootloader:

    adb reboot bootloader

  3. Double-click the flash.bat script inside Platform Tools — the recovery is flashed automatically and the device boots into recovery. If it does not:

    fastboot reboot recovery

  4. After booting into recovery: Format / reset data (mandatory).

  5. Back in the recovery menu: Apply update → Apply from ADB, then:

    adb sideload "drag and drop the custom rom zip here"

  6. When asked whether to reboot to recovery for additional files:

    • Yes — if you want to flash GApps yourself.
    • No — if it is already a GApps build.

  7. Format data (optional but recommended) from the recovery menu.

  8. Reboot to system.
