*Removed the console loading screen (no more console at all) *Complete rework of device handle. You need to reset all your custom paths for this rev. *Support for writing images/settings/... on any writable partition (FAT/NTFS/EXT). (Theoretically you can run the loader from NTFS only without the need of any other partition or SD if run from new forwarder channel, for example) *Support for Primary/Logical partitions and GUID Partition Table (GPT) Forwarder Channel in last revision was not using IOS58 (not sure about AHBPROT) Here a corrected version (thx to Cyan): http://www.mediafire.com/?a9y3ywqcm4v3lz3
