The first is that (obviously) the test points are checked right in the ROM bootloader and will always work. The "grounding USB D+" is in XBL and is dependent on whether the code is in there.

Also it necessitates standing on your head and having the timing correct.

Yes the timing is a pain, but the same goes for shorting the EDL pads and getting in to Recovery. It's just trial and error until it finally works. I still haven't found a consistent way of getting in, I just keep holding all 3 buttons and release them randomly until I hear/see it being detected by Windows.

Onyx (so far) has been very accomodating and not using Secure Boot.
One last shot in the dark is this loader: https://github.com/bkerler/Loaders/r...5106_fhprg.bin
It's for an SM/SMP_AGATTI.

No luck, same result as all the others.

Waiting for Firehose... No response, poking...
Could not write device

So the only difference between QCM and QCS 2290 is LTE support. Is there a loader for QCM4290/QCS4290? They're also mentioned in the spec-sheet. How do you find these loaders? Do you have to download them all and open them with qcomview.exe to see which chipsets they support?

Maybe a loader for Qualcomm 630 (which CPU-z misidentifies it as) might work? I'm trying to figure out how the Python EDL program works while I'm waiting for the UART-USB to arrive.
