Renesas V850ES Fx3 / Fx3-N Locked UART Script for iProg Pro
The Renesas V850ES Fx3 / Fx3-N Locked UART Script for iProg Pro is a professional software solution designed for reading, writing, and cloning secured (locked) and unsecured microcontrollers via the UART interface.
The script only works with original iProg Pro programmer! Please write Serial Number and UID in the order.
Equipped with a proprietary security bypass algorithm, this script allows automotive technicians and engineers to extract full dumps without errors. It is an indispensable tool for working with VAG BCM2 modules, Body Control Modules (BCM), instrument clusters, and various body electronic units
Key Features & Capabilities
- Security Bypass Algorithm: Specially engineered routine bypasses built-in protection to read secured MCU contents cleanly and reliably.
- Full Read & Write Access: Comprehensive reading and writing of both CodeFlash and DataFlash memory areas.
- Auto-Detection: Automatically detects the connected microcontroller model, CodeFlash size, and DataFlash size.
- Chip Erase & Protection Configuration: Full chip erase function, along with the ability to set or modify hardware protection bits.
- Special Erase Routine: Features a unique procedure designed to attempt erasing fully locked MCUs even with the strict "Disable Chip Erase" protection bit activated.
- Full Cloning & Data Recovery: Extract complete, uncorrupted binary data required for file editing, module adaptation, or 1:1 hardware cloning.
Practical Applications
Renesas V850ES family microcontrollers are widely used across modern automotive electronics:
- VAG Group BCM2 Modules: (Audi, VW) key programming, cloning, and module repair.
- Instrument Clusters & Dashboards: Mileage recalibration, repair, and data transfer.
- Body Control Modules (BCM): Data recovery, cloning damaged units, and electronic component replacement.
