Medion P6705 laptop: failing to install Big Sur

[Feartech]

I'll look into that.

Another thing I forgot about: the OS thinks I am on battery even when connected to charger. Battery percentage shows, but it does not update in real time. I did try adding SMCBatteryManager.kext and ECEnabler.kext. Those did not help. They helped me on my other laptop. I'm guessing this laptop needs something more.

may require hotpatching:

So tried to install Big Sur again on a different SATA HDD. Another fail from the looks of it.

It got all the way to "Less than a minute remaining" on the Apple logo (black background) and has now halted. There's no HDD LED activity and the CPU fan is running faster than normal (indicating it's running more hotter than when it's actually working fine). It's been like this for about 2-3 hours now.

I saw from some Google searches that people had success by simply waiting hours. It doesn't seem to work for me though. I waited 7 hours last time and nothing.

Not sure why Big Sur just won't install.
