There is no cron daemon running. Updating the EPG seems to be done by Java code.

In order to extract the firmware take a wireless sniffer and watch the iPronto connect to the update server. Some more steps and you can rebuilt the files and notice how outdated this software is. The software levels were shocking to me.

What enhancements has the iPronto Team done? They even removed features like the 4 M view instead of fixing it and stabilizing the code.

The code has a backdoor but presently I refuse to publish it because the average user would be at high risk killing the iPronto. There seems to protected boot code to recover, so maybe it can be published lateron.

There are more possibilities to access the device but why should I tell Philips?
