Hello CyanLabs community, I’m currently working on recovering a soft-bricked TCU (Telematic Control Unit) in my 2020 Ford Fusion SE EcoBoost. Details: • TCU Part Number: LB5T-14G087-SE • Calibration Level: LB5T-14G087-SE • Issue: TCU is detected in FORScan but modem serial (ESN) is missing, FordPass Connect not working. • Need: Looking for the VBF firmware files (strategy/calibration) for this TCU to manually reflash. I’ve tried TCU module resets and As-Built edits. FORScan does not offer the “Firmware Update” option, so I need the VBF files to attempt a manual flash. If anyone has these files or can point me where to get them, I would greatly appreciate it. Thanks in advance for your help! ---

There’s a switch somewhere withing the programming interface that forces suspension of other devices on the bus, i’m not sure if that applies here. ---

What files are you trying to load? The SBL is either wrong or missing.. Can you see the asbuilt and what firmware files are currently loaded? ---

Most of the time you don’t need to silence the busses, but in certain cases yes, especially for the APIM and BCM. This won’t load the SBL, so there is a different issue. ---

I updated the APIM and it worked but the TCU isn’t working at all, its giving me hard time to know what’s preventing it from updating or functioning ---

Unplug the power connector from the TCU for a few minutes then reconnect and try again. ---

That TCU might have issues. These usually work right. Can you access the asbuilt? ---
