How the MS450H downloads new firmware
Hello,
here is what I have found listening to the communication my player had with the LG server:
The player asks for a new version by connecting to server aswnus.lge.com port 80 (i.e. standard http connection) with the following request:
1. The Content-Length is calculated based on the encoded body length
2. The body is sent base64 encoded
3. The IMAGE_VER data is the current firmware version of the player
4. My player is the MS450H, which is internally marked as MS400D as can be seen from the request. I cannot tell whether it is the same for LG MS400H (and the product ID too), this would have to be confirmed by a MS400H owner who would do the same as me.
The answer from the server is:
1. The Content-Length (in the header) is calculated based on the encoded request length
2. The body is sent base64 encoded
3. The body does not have any line ends (but that is no error, just "it is so")
Based on this answer, the player asks for the firmware by issuing the following request (after the user agrees to download the new firmware), again from aswnus.lge.com, port 80:
HEADER:
The answer from the server is:
