COS'È KORHEX?
Un componente aggiuntivo per Flex per l'accesso diretto alla MCU
Korhex è un componente hardware aggiuntivo per Flex, progettato per l'accesso diretto alla MCU durante le procedure di sblocco delle centraline supportate. Funziona con il flusso di lavoro Boot Glitch di Flex per semplificare l'accesso alle centraline protette, riducendo la necessità di capovolgere la scheda, dissaldare le resistenze e cablare manualmente i pin di Boot.
Lo sblocco di una centralina protetta di solito richiede un lavoro fisico prima di qualsiasi passaggio software: capovolgere il PCB, dissaldare le resistenze, cablare manualmente i pin di Boot. Ogni passaggio aggiuntivo aumenta il tempo di lavoro e il rischio di danneggiare la scheda. Korhex è stato creato per semplificare questa fase, offrendo un singolo punto di contatto dedicato alla MCU anziché interventi manuali.

Highlights:
Direct MCU access on supported ECUs
No component desoldering
No manual pin connection
Support for advanced Boot Glitch procedures
Full integration with the Flex ecosystem
Features:
Deeper ECU Access
Korhex replaces manual bench preparation with a single MCU contact point, run through Flex.
The result isn’t just less prep time, it’s a new way to program control units: a revolutionary connection mode and an advanced access to highly requested, previously unavailable modules.
Boot Glitch Technology
Advanced unlocking procedures developed for protected control units.
New MCU Perspectives
Designed to support the evolution of modern automotive microcontrollers.
Flex Integration
Dedicated procedures and guided workflows built into the Flex ecosystem.
Enhanced Workflow
Reduce physical preparation and simplify complex bench operations.
Growing Coverage
A platform designed for continuous protocol and application development.
How Korhex works?
Korhex has been designed to integrate advanced hardware access directly into the Flex ECU programming workflow. It interacts directly with a specific contact point on the ECU microcontroller to enable the access required by supported advanced programming and unlocking procedures.
Korhex uses a specific contact point on the microprocessor to perform the access procedures provided for supported devices.
Thanks to Boot Glitch technology and integration with Flex, the workflow requires less preparation and reduces physical handling of the ECU board.
1. Connect & Position
Prepare the ECU per the Flex-guided procedure and place Korhex on the designated MCU contact point via its dedicated masks.
2. Access & Unlock
Perform the required access and unlocking operation on supported ECUs - no desoldering, no manual Boot pin wiring.
3. Unlock
Run the access and Boot Glitch procedure provided for the supported ECU.
4. Program
Continue directly in Flex with the standard programming procedure. The workflow is now integrated end-to-end inside the Flex procedure you already use.

Korhex FAQ
What is Korhex used for?
Korhex is used during supported advanced ECU access procedures where direct interaction with the microcontroller is required. Depending on the ECU and Flex protocol, this can include Boot Glitch and other ECU unlocking procedures.
Is Korhex an ECU programmer?
Korhex is not a standalone ECU programmer. It is a dedicated hardware extension of Flex. Flex manages the supported procedure and subsequent ECU programming operations.
Is Korhex a standalone tool?
No. Korhex has been developed specifically for the Flex ecosystem and operates through dedicated procedures available in the Flex software.
How does Korhex access an ECU microcontroller?
Korhex is positioned on a specific MCU contact point indicated by the corresponding Flex procedure. The hardware enables the required interaction with the microcontroller during supported access or unlocking operations.
Do I need to desolder resistors?
Korhex is designed to avoid resistor desoldering on supported procedures where direct MCU contact can be used instead.
Which ECUs are compatible with Korhex?
Compatibility depends on the ECU, microcontroller and Flex protocol. The list of supported applications is continuously updated through Flex releases and can be checked in the Flex Vehicle List.
Do I need a specific Flex license to use Korhex?
Customers with a Flex Full Master or Full Slave configuration can use Korhex with the procedures included in their software package.
Customers without a Full configuration can purchase the Flex Boot Glitch License FLS0.20M/S to access supported Korhex procedures.
Will new ECUs be added?
Yes. Korhex has been designed as an evolving hardware platform. New supported applications and protocols released through the Flex ecosystem.
