We do know where that signal is. For RGH3 you have to scrape the solder mask off a via. This is CPU_PLL_BYPASS.

Sorry which sentence are you referring to?

iirc that sentence refers to the time period where rgh3 didn't even exists (when the slim model just appeared). When I finally talk about RGH3, that's when CPU_PLL_BYPASS is mentioned:

Fast forward to November 2021, 15432 surprised the community again by publishing RGH 3.0, a universal RGH variant to rule them all. Behind the scenes, the new technique is an evolution of RGH 1.2 V2 that doesn't require a glitcher anymore. This was done by implementing the glitching stage into the SMC, which now only needs two wires soldered on the motherboard (in particular, CPU_DBG1_POST1 and CPU_PLL_BYPASS) to execute the hack.

I guess I could amend it with "(...) which now only needs two wires soldered on the motherboard (in particular, the newly located CPU_DBG1_POST1 and CPU_PLL_BYPASS) (...)" or something like that?
