Yup why not just tell me your email and I'll try to slipstream drivers so that you can run windows 7.
B.T.W, I already slipstreamed the drivers in Windows 7 for the AMD 1600x CPU and all was fine. But it looks like it is the GPU in the 2400G that is causing trouble, also it has two sets of new drivers, AMD-Ryzen-Master-UI and Win10-64Bit-RV-AM4-Radeon-Software-Adrenalin-Edition-Q2-2018-May17.
Umm... do you know what are you talking about? phlash17 is meant for legacy Phoenix bios flashing; it is not at all meant for AMI Aptio UEFI firmware.
