The BootROM Cable for Cummins CM2100A (FLX2.75) is the ideal solution for performing read/write and recovery operations with the FLEX programmer on Dodge and other heavy-duty Cummins platforms.

This cable enables direct communication in BootROM mode, providing full access to the ECU for recovery or reprogramming when standard operations fail — such as after a corrupted or incompatible flash.

BootROM mode is available free of charge via the FLEX “Enable BootROM” function, ensuring a safe and reliable recovery process.

Main features:

  • Bench-mode connection for CM2100A ECUs
  • Enables BootROM mode for locked or bricked ECUs
  • Full firmware programming (read/write/verify)
  • Direct communication bypassing operational firmware
  • ECU recovery from corrupted or failed flash attempts
  • Simplifies recovery without needing to boot in standard mode

Compatibility:
Cummins CM2100A ECM (common on Dodge Ram and heavy-duty applications).

Requirements:
FLEX / FLEXBox interface (active subscription required), bench power supply and proper breakout/boot wiring.

Typical use cases:
ECU recovery after failed programming, firmware restoration or cloning, safe bench operations independent of vehicle connection.

In the box:
