Invalid magic response

[tsgan]

When I run qdload.pl it stops at:

Sending MAGIC... SENDING: 7e 01 51 43 4f 4d 20 66 61 73 74 20 64 6f 77 6e 6c 6f 61 64 20 70 72 6f 74 6f 63 6f 6c 20 68 6f 73 74 03 03 09 c6 32 7e sendPacket: 40 readPacket_retval: 0 Invalid MAGIC response.

But when I disable doStage1 and run qdload.pl it reports this:

tsgan@tsgan-virtual-machine:~$ sudo perl qdload.pl -pfile MPRG8064.bin -lfile unbrick_ifc.img -lreset Sending MAGIC... SENDING: 7e 01 51 43 4f 4d 20 66 61 73 74 20 64 6f 77 6e 6c 6f 61 64 20 70 72 6f 74 6f 63 6f 6c 20 68 6f 73 74 03 03 09 c6 32 7e sendPacket: 40 readPacket_retval: 1 RECEIVED: 03 00 03 33 1b Response: 03 00 03 Invalid MAGIC response.

How to solve this issue?

thanks,
