Where can I get FW for flashing GSA-4120B@GSA-4160B?

Where can I get FW for flashing GSA-4120B@GSA-4160B? :wink:

:bow:

There were certain experiments done in attempts to cross-flash the GSA-4120B to a GSA-4160B. These had fairly serious side effects and so was not considered entirely successful. As a result, the project was more or less abandoned. See this discussion for more details :

The hacked firmware was never released openly to the public, only to a few testers. So you cannot get hold of the hacked firmware. Since the project was not really successful, it means you cannot properly cross flash a 4120B to a 4160B. Do not try.
