How to Open Diag Port on OnePlus, Realme, or OPPO Smartphones

Among the popular Android devices in the market are OnePlus, Realme, and OPPO smartphones, which come in two variants – one with Qualcomm and the other with MediaTek chips. Both variants offer excellent features and performance, but what sets Qualcomm devices apart from the rest is their ability to open a diagnostic port. With this port, users can access a range of diagnostic tools to troubleshoot their device effectively.

What is Diag Port?

A Diag port is a special diagnostic port used to test and troubleshoot electronic equipment. This port is typically found on computers and other electronic devices. It allows technicians to connect special diagnostic equipment to the device to test its functionality. It is used for various purposes, including system troubleshooting, debugging, and performance analysis.

Diag Port on smartphones is used to repair the IMEI number of Qualcomm Snapdragon-powered smartphones, including the ones from OnePlus, Realme, and OPPO. However, it’s worth mentioning that the MediaTek processor-powered smartphones do not require opening the Diag port for IMEI repair.

Note: Before proceeding further, ensure you have a rooted device with proper root permissions for these to work.
