The inside of the MacBook looks perfect. But when you try to install the OS, the MacBook reboots! I tried to restore it via DFU, but the result is the same. The MacBook works until you try to install the OS!

Can you access security settings on internet recovery?

When turned on, the touchbar flashes several times. Apparently, the touchbar interferes with loading, I thought and transferred the motherboard to a test MacBook of the same model. The MacBook recovered and works normally except for the constantly glowing touchbar backlight.

So even other touchbar flashes?

When turning on the MacBook, another sensor also flashes several times. Then the MacBook boots up but the touchbar does not work correctly.

This problem persists with different touchbar?
