⚠️ Flashing Risks & Disclaimer
Updating or recovering a OnePlus 8 IN2017 with a full OxygenOS 12 ROM such as C.41 can cause boot or network issues if used on the wrong variant (for example, IN2015 or converted global units) or if applied while rooted with mismatched boot images. Downgrading from Android 13 or from newer C‑branch builds to C.41 may also introduce risks like data loss or anti‑rollback constraints, so backups and version checks are essential. The C.41 package and OxygenOS trademarks belong to OnePlus and are mirrored by third‑party hosts only for restoring or updating legitimately owned IN2017 devices.

The C.41 full ROM for IN2017 is no longer easy to obtain directly from OnePlus support pages, so it is preserved by firmware archives and mirror sites. This package is an original OnePlus IN2017 C.41 ROM mirrored for preservation, as the manufacturer does not keep every historical carrier build visible on public download portals.

Flashing Requirements
- OnePlus 8 IN2017 hardware (T‑Mobile/Sprint) confirmed via Settings → About phone or fastboot model; do not flash on IN2015/IN2011/IN2013.
- Battery charged to at least 40–50% before initiating a full ROM update.
- For standard updates, a working OxygenOS system with local update support or recovery sideload capability; for bricked devices, Qualcomm EDL flashing via OnePlus/ carrier tools may be needed.
- Back up important data, since attempting repairs from a heavily modified or rooted state may require a clean flash that wipes user partitions.
- Unlocked bootloader is only necessary for rooting or custom ROMs; official C.41 flashing processes assume a locked bootloader.
How to Flash / Apply OxygenOS 12 C.41
- Download the OnePlus_8_IN2017_EX_11_C.41_220723.zip file to a PC, verify its size (~4.65 GB), and then copy it to the phone’s internal storage if using local update, or keep it on the PC if planning an ADB sideload or service flash.
- If local update is available on the IN2017 build in use, open Settings → System → System updates, tap the menu (⋮), choose “Local upgrade” (where present), and select the C.41 zip; otherwise, boot into recovery and use “Install from storage” or “ADB sideload” to apply the package.
- Confirm that the build being installed matches IN2017 and that the device is already on a compatible OxygenOS 11/12 base to avoid downgrade/rollback issues, especially if coming from a newer Android 13 firmware.
- Start the installation and wait without interrupting power or disconnecting the device; the phone will verify and then install the C.41 payload, which can take several minutes.
- After completion, allow the OnePlus 8 to reboot into OxygenOS 12 C.41; first boot may be slower than normal while Android 12 optimizes apps and updates system components.
