Description

The Special Developers Edition (SDE) firmware is a very useful resource, and this page presents the modifications implemented in the patched version of the SDE firmware. One of the main features of the SDE firmware is the fact that when the device boots into it, the bootloader locks some parts of the flash memory and thus makes it very hard to break a device. This firmware will also not verify the signature on the normal kernel and initramfs, allowing you to replace them with your own. However, all other bootloader parts that are cryptographically signed in the normal firmware line are also signed in this firmware, preventing you from modifying them. This is mainly why we release this patched version of the SDE firmware.

  • Removed the signature checks in boot0 and boot1, allowing for the replacement or modification of the recovery console.
  • Removed the HDD lock from the recovery console, allowing you to replace the hard drive in your device.
  • Removed the signature and version checks from the recovery console, allowing you to downgrade to any firmware version or install unsigned firmware updates (.aos files).
  • Removed the shell script which clears the system partition, allowing you to easily revert to the original firmware (see below).

How to Revert

Reverting from this firmware is a two-step process:
