Iprog Rework ((free)) -

The USB-to-UART bridge can be flaky, causing disconnection.

To achieve optimal results with iProg rework, follow these best practices:

An iProg rework station typically consists of a heating system, a vacuum system, and a temperature control unit. The process of reworking a PCB using an iProg station involves the following steps:

| Symptom | Most Likely Cause | Solution | |---------|------------------|----------| | Device not recognized by USB | Damaged CH340G during soldering | Replace CH340G; check D+/D- traces | | Reads random data (0xFF or 0x00) | Bad crystal or clock | Re-solder crystal caps; check for solder bridges | | Vpp never reaches 12V | Blown transistor on charge pump | Replace Q1 (usually 2N3904 or S8050) | | Overheating after 2 minutes | Short in power mod circuit | Check for solder balls under MP1584 module | | Firmware flash fails | Wrong bootloader configuration | Use Pickit3 in "Low Voltage Programming" mode | iprog rework

This article provides a comprehensive guide to understanding why an is necessary, common failure points, and the steps to improve your tool's performance. 1. Why Rework Your iProg+? (Common Issues)

: A premier forum for automotive software and hardware where users share detailed iProg PCB "maps" for reworks. Digital Kaos

: Locate the main power inductors (usually marked 100 or 220). Replace them with high-quality, high-current shielded inductors of the same value. The USB-to-UART bridge can be flaky, causing disconnection

The most common point of failure is the 5V and 3.3V power regulation.

Users report that after the rework, the tool successfully handles complex jobs—like resetting Subaru Smartkeys or clearing Toyota airbag modules—that previously failed.

Add an MCP2515 CAN controller and MCP2551 transceiver to the IProg's expansion port. With custom firmware (available on GitHub), your IProg can read/write CAN-based dashboards and ECUs without disassembly. Digital Kaos : Locate the main power inductors

To perform these modifications, you will need standard soldering equipment. You can find specialized kits or components from retailers like:

Low-grade power management components prevent proper current sensing and stall high-power adapters like RFID or BDM. Step-by-Step Component Replacement Guide

Another common hardware fix involves modifying the mainboard by correctly repositioning a capacitor and resistor (components C9 and R6) that are sometimes swapped on the board.
