I
I need help restoring a Mercedes HU55 High. I was updating the device, forgot the key in my pocket and walked away from the car, which caused the ignition to turn off. The device is now in a "soft brick" state. I've completely lost access to DOIP/Ethernet. The device is in a boot loop, but continues to communicate via CAN UDS.
My configuration:
I'm trying to flash just the bootloader via CAN to restore access to the DOIP. I'm successfully doing this:
However, the firmware process is immediately interrupted at the WriteFingerPrint recording stage with NRC 22 (Conditions Not Correct).
Log fragment:
I'm stuck at this point. If anyone could help me solve this problem or suggest how to proceed so that the bootloader loads successfully, I'd be very grateful.
My configuration:
- Hardware: HU55 High, Bootloader_CY17_2
- Interface: Openport 2.0 (PassThru J2534)
- Software: DTS Monaco 8.16
- Protocol: UDS_CAN (since DOIP is down)
I'm trying to flash just the bootloader via CAN to restore access to the DOIP. I'm successfully doing this:
- Open a session (10 02)
- Access/Unlock Security System (27 11 -> 67 11)
However, the firmware process is immediately interrupted at the WriteFingerPrint recording stage with NRC 22 (Conditions Not Correct).
