Thank you for such a quick response. the I747 does use msm8960. I have tried what you supplied me with, and after some attempts It hasn't quite got me in.

Unable to receive response

It seems to execute hex.bin, but then does not get a response back, or is not getting the response it wants, and it bails after that.

So, this is what the connection status was right before running the perl script:

lsusb:

Bus 002 Device 005: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

dmesg:

[59535.023957] usb 2-1.7: new high-speed USB device number 5 using ehci_hcd
[59535.116833] usb 2-1.7: New USB device found, idVendor=05c6, idProduct=9008
[59535.116836] usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=0

[59535.117351] usb 2-1.7: Qualcomm USB modem converter now attached to ttyUSB0

Then, I run the first perl script, and get the error mentioned above. lsusb has the same output, and dmesg is very similar, but it shows that the phone disconnected, and reconnected as evident by the "USB Device number" being incremented.

[59731.417114] usb 2-1.7: USB disconnect, device number 5

[59731.709942] usb 2-1.7: Qualcomm USB modem converter now attached to ttyUSB0

since I couldn't hold back my curiosity (it can be a dangerous thing....) I ran the second one, even though the first failed.

it ran with this output:

lsusb and dmesg appear exaclty as before, with no disconnects or -reconnects.

Thanks for your assistance with this, I will continue to troubleshoot and let you know if I come up with anything.
