PC was acting up so didn't have time to set up a virtual linux machine to build it.Thanks, wanted rule that one out.
I used "X722_stable_20s_NoRoot_tora33.zip" ROM as my source for "Extract proprietary blobs" step and Adreno driver (a530_zap) files.
Great, let us know your findings! In order to build on my distro I had to downgrade both python (from v3 to v2) and 'curl' app. @slothdnk 's guide doesn't mention about picking patches which I did.
If there's a way to enable file logging (or logcat) for GPU and boot events that might help track if you face the same boot-time issue.
I've got 2x Xeon 8c*16t with 16GB of ram and a NVME SSD (Samsung 960EVO). I think it should be okay to build.
Internet connection is 200/20.
