Thanks to Kernowkoi for his very much detailed instructions with Hi-Resolution pics, tried the interface with Comcast 1067 and its Downloading/Uploading the file.
Now i want to upgrade JP1.3 Remote, but its not getting recognized, anyone has any idea which model is it.
On the battery Cover its written
URC-60500RO1-11,There is similiar looking remote thread here

but its different model, i tried URC-7555 & URC-1660 But No Luck.
If i do Raw Download I get this message "No RDF matches signature starting 3056"
