Some of the KEY is not in the mboot file .And the must be very accurate. How to determine key bank offset?

dipcore commented 7 years ago

look at the https://github.com/dipcore/mstar-bin-tool/blob/master/extract_keys.py There is an explication of how to find the offset.

The easiest way is to open mboot.bin with any hex editor and do search by string "Mstar.Key.Bank" You should get two equal sections, the key bank and the key bank backup.
