Things are starting to fall back into place since the release of FW 6.2.0 as hactool 1.2.2 now supports Nintendo Switch FW 6.2.0!
Compilation is still annoying, so a pre-compiled build is provided for Windows users.
Since the last release, the following bugs were fixed:
To use hactool you’ll need to insert tsec_root_key/master_kek_source_## into prod.keys manually just like any other keys.
-Support was added for 6.2.0+ new key derivation using tsec_root_key and master_kek_source_##.
-6.2.0 keydata will no longer be called “Unknown”.
-A bug was fixed involving argument violation to mbed_tls aes routines.
The following Switch file formats are supported:
“Keydata can be baked in at compile-time, or loaded from an external key file. See README.md and KEYS.md for details. In addition, a secure boot key + TSEC key + boot0 file pair can be passed in with an external key file to derive all keys it is possible to know given the information one has.”
