Project Stellar - Firmware Update 1.4.0

Project Stellar - Firmware Update 1.4.0

Hello everyone!

We're excited to share the release of firmware version 1.4.0 for Project Stellar. In this update, we will be tackling one of the last remaining mysteries of the original Xbox.

OEM Hard Drive Unlock and Key Recovery

From lost childhood saved games to lost media, such as DLC and title updates, the Xbox has historically had one problem. Losing the secret key to the hard drive meant no longer being able to access its contents.

With Project Stellar firmware update 1.4.0, that's no longer the case. Using advanced recovery techniques, we can now recover the hard drive key/password to any OEM hard drive.

It doesn't matter if the EEPROM is corrupt or if it's an entirely different board altogether. Stellar will automatically step you through recovery and the unlocking process.

Hard Drive Unlocking/Locking

In addition to hard drive key recovery, firmware v1.4.0 adds additional controls for manually unlocking and locking drives to the motherboard. This a great handy tool for people using Project Stellar as a recovery tool on other systems.
