usbloadergx/source/prompts/filebrowser.cpp
dimok321 7bccfd2b17 *added loading screen 
*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):
