I actually tried to upgrade to DSM 7.x TCRP but after loading, it hangs in the loading kexec. tried different USB drive, but still have the same.
I am actually using my old hardware which works with DSM 6.x.
Procie; AMD Ryzen 3 3200g
RAM: 2x8GB T-Force Delta
Mobo: MSI B450M
Maybe my hardware is not compatible with DSM 7.X?
