Howto flash Huawei HG655d using CFE?

Hello,

I am trying to flash OpenWrt onto a Huawei HG655d device. According to the documentation, this requires a JTAG cable to replace the CFE bootloader. Is there any information out there for beginners on how to do that?

I have managed to connect the board via serial console to my GNU/Linux PC. This is a log of me trying to flash the OpenWrt-bin-file using the CFE webinterface. If I try to enter a command at the CFE prompt, I always get command status = -1. After the upload, I get a RSA verified failed.

On the device's page, both serial and JTAG pins are present - on my board, only the serial pins are soldered on. I don't think I will be able to connect a JTAG cable to the PCB...

Can someone help me, point me in the right direction?

Thanks,
Frans-Willem
