Everything you can replace in the flash is resigned when you replace it.

Also, when the extract option is enabled, the files will be extracted after the replacement/resigning.

!! This tool will never overwrite your existing flash dump file! You must specify an output. !!

This release includes no keys and I will never release keys.

You must create your own keyfile if you have keys. Look at keymgr.h for the format.

Look at the fail0verflow article if you want to try and derive the keys yourself. There may be some bugs with this release.

Shoutout to Team Molecule for ARZL decompress, zecoxao for some NVS information on the wiki, SKFU and iqd for SLB2, and many anonymous contributors!
