How to Repair LAUNCH SmartLink Firmware (2 Methods)
LAUNCH SmartLink not only supports various vehicle protocols (such as DoIP and CAN), but also allows technicians to remotely assist with diagnostics. If a SmartLink device malfunctions, firmware repair can be attempted first. This article will introduce two methods for LAUNCH SmartLink firmware repair.
Method 1: Perform the repair directly on SmartLink
1) Connect the SmartLink C V2.0 to the OBD diagnostic port and power it on. Waiting for the computer to boot up.
2) First, ensure a network connection:
Click the settings icon in the upper right corner, select [WLAN], choose a network, and connect.
3) After configuring the network connection, perform the repair: Click the settings icon in the upper right corner, select [Firmware repair] -> [Star Repair]. Just wait for the upgrade to complete.
