Hi Fam, good morning.
I have an 820-3332 which, after U8900 resolder, replacement, and all sorts of possibilities, was not completing the boot on any system, neither from internal or external drives.
So, I run the jumpers to bypass the dGPU and it looked perfect until I tried to run the Catalina install and it simply didn't finish, giving a Kernel Panic a little before the installation end.
I tried to install Mojave, and all was perfect including the system security updates.
Any ideas?
BTW, I didn't remove the 2 inductors the bypass step3) ...
