How to Check for and Install the ColorOS 17 Update on a OnePlus 15
Check Settings for the India-specific ColorOS 17 rollout on your OnePlus 15, and install only the update offered to your device.

Check before you update
The supplied OnePlus Community announcement says the stable ColorOS 17 rollout is reaching OnePlus 15 phones in India in batches. The India build listed is CPH2745_17.0.0.102 (EX01). If your phone does not show an update yet, it may not have reached your device; the announcement does not give a schedule for each handset. Read the OnePlus Community rollout notice.
Before checking, connect to a reliable Wi‑Fi network and make sure the phone has enough battery. Verify that your important files are backed up and that you can access that backup before starting an installation. The supplied sources do not specify a required battery percentage, free-storage amount, or backup method, so don’t rely on an invented threshold.
Check for and install the update
Open Settings on your OnePlus 15.
Tap System & Updates, then Software Update. This is the menu path reported for checking the update; labels can vary with the software already installed.
If ColorOS 17 is offered, check that the device is your India-market OnePlus 15 and that the update details show the India build
CPH2745_17.0.0.102 (EX01)before proceeding. Do not use a build intended for another region.Tap Download now if that option appears. Wait for the download to finish, then follow the on-screen installation prompts. Keep the phone powered and do not interrupt the process. The supplied instructions do not document every screen after downloading, so follow the prompts shown on your own device rather than assuming a particular button or restart sequence.
Stable update versus beta
This guide covers the stable rollout, not beta enrollment. A beta is separate software and may have issues; the supplied sources do not establish that a beta is necessary to get the stable update. Avoid changing regions or manually installing a package based on instructions for another model or region.
Troubleshooting
No update appears: The India rollout is described as staged. Check Software Update again later; no specific wait time is confirmed.
The build or region does not match: Stop and do not install it. Use the official OnePlus Community rollout thread for the listed region and build information.
A download or installation fails: Preserve your backup and use the on-screen error details when seeking help in the official community thread. The supplied sources do not give a recovery procedure or guarantee that an interrupted update can be restored in a particular way.
