Is it possible to use RD-PQ Firmware with Retail I9300?

If yes, then please how?

Please, don’t try at home, without to know how… risk to brick I9300.

But maybe someone has broken I9300 with cracked/damaged Display or is smart enough to use “Live Demo Unit” I9300X…

Maybe JTAG enabled…

Thanx in advance.

Best Regards
