Problem:
Tried to unlock a Mercedes MD1CP007 ECU with Flex + Korhex programmer.
What concerns me is the LED status:
Software shows Connected
Antenna: Ready
Voltage: 19 V
But the RGB LED near the USB/power connector keeps flashing red continuously
According to the Korhex manual, flashing red indicates an error condition related to voltage or antenna, while green means ready to use.
This is contradictory, because the software shows that the antenna is ready and the voltage is present, but the hardware LED still indicates an error.
Does this indicate a hardware/firmware/power issue?
Solution:
The red light will flash until you open a protocol that needs Korhex. Once you open a protocol that needs Korhex, the light will become green and when it is actually glitching it’ll become blue.
That’s normal until you open the protocol for glitching and then it will change to green.
It actually needs to see a locked ECU on id for it to even activate,
If it does an ID and knows it’s unlocked it will remain flashing red.
So the flashing red LED does not necessarily mean there is a fault — it can simply mean that Korhex is connected but not currently engaged with a locked ECU.
