We have just released PS3Key v3 updates for both Atmel and Silabs-based PS3Keys and also made the open HEX code available. All of this is available in the download area at: http://www.ps3key.com/en/members/downloads/
The v3 update adds the functionality of the popular "Hermes v3" payload, with various modifications. Note that no serial number is required to download the open HEX update which can be be used on generic AVR devices.
In the past few weeks we have received several requests from distributors and end users who wish to be able to flash their PS3Keys with the very latest firmwares that are not yet available from ps3key.com.
As customer satisfaction is our number one priority, we have decided to release material and source code necessary to make this possible in the very near future.
The PS3Key update system was designed to protect end users from bricking chips with bad updates. A word of caution is therefore necessary here. If you experiment with custom updates your WARRANTY WILL BE VOID, and it is possible to BRICK the Atmel version of so that an external AVR programmer is necessary to restore any functionality. Generic AVR-based dongles and SiliconLabs-based PS3Keys are safer for experimenting with custom updates.
If you wish to use the product as advertised we strongly suggest you do not experiment with custom firmware unless you have some AVR experience and an AVR programmer on hand just in case.
We are now working on modularising the code and will release an update incorporating the "Hermes v4" features soon. We will also make source code and material for generating custom updates available soon. While compiling custom updates might add bleeding-edge features not yet available in the official PS3Key, it is not something we recommend for inexperienced users.
Preferably, please be patient and trust us to deliver a safe update solution for you. It might take a little longer than the other versions available on the web, but you'll have the piece of mind that you're covered by our warranty in the unlikely event that something does go wrong.
Thank you for your continued support of PS3Key!
