Just a quick question / concern .. Just ran an analysis on your file here -> link
While I can't see too many differences after unzipping your exe and running a comparison with a hex editor against your original odin you provided .. still the online analysis results do make me ask the question
Online analysis of your original odin provided is here -> link
The patches/changes are:
Operationally I patched as indicated in the OP (encryption and model fails).
All other changes are visual. ie. main graphic bar, version code, and url text/address.
That is it. Simple and has helped many to flash their phones!
