Guys,
I am a newby to this forum and am highly interested in your attempts to open up the Philips box, i initially became frustrated with the possibility of ending up with a door stop when my subscription ends. I am slightly lost as to exactly were we are with this can anyone please bring me up to speed with the following questions:
- Firstly, I understand you have been able to get through most of the boot up sequence by using the debug firmware signature files found on the BT Server and also using the JTAG cable to patch out the signature checks, but everything fails when it tries to load the user data! Is this a correct assessment of the current progress?
- Second i believe you can boot Linux on the device but this is currently amounts to a router without the required hardware drivers?
- Third is there any use in creating an internal TFTP server so that the box attempts to download files from there rather than over the net?
- Fourth is there any way to extract the user data and point the vision box at an internal TFTP server or get it to download from somewere else?
- And Finally is there anyway at all to get the box running standalone?
I am keen to get involved with the project and am looking foward to buying a second box on ebay to help with progress.
Thanks

Hi Dave,
1) you are correct, jtag can defeat all the signature checks, and you can then run anything you like on the box. The debug firmware only lets you modify the content files and not programs.
2) Linux, yes you are correct again. No drivers :( as yet, altho I may know someone who can help...
3) Unsure... Ideally I would like to patch the software so the box does not need this.
4) Maybe... you could dump the boxes ram after it has booted up and running correctly... and you can modify where it downloads its bootstrap from in the tv2client.xml file.
5) Thats what I'm trying to do too... are you any good with C# ?
Hope that helps :)

2) Linux, yes you are correct again. No drivers :( as yet, altho I may know someone who can help...
the drivers are there, but the DSP microcodes wont load for some unknown reason.
without the microcodes the drivers do not work.
3) Unsure... Ideally I would like to patch the software so the box does not need this.
its not needed to code anything for that. there is a "standalone" mode included, where it will fetch the data files from local hard drive.
not sure if it works, but I guess it is there to have the box working in demo-cases where no connection to a real IPTV server is possible.
4) Maybe... you could dump the boxes ram after it has booted up and running correctly... and you can modify where it downloads its bootstrap from in the tv2client.xml file.
I think the easiest way would be to add a network traffic logging into the application to store the unencrypted data to disk.
5) Thats what I'm trying to do too... are you any good with C# ?
I am still in favor of a rewrite... the full skinable UI in C# seems to be a bit too much for the CPU... a faster UI would be nice :)
Thanks that's great, now i need to hop on to ebay :)
