How to enter flash mode

Hold Power + Vol Up, enter to fastboot protocol

Memo

Using GCC6,

Mostly flashing method doesn't work, but pmbootstrap install --sdcard is OK,

boot topmbootstrap flasher boot

I'm not recommended flasher flash_kernel, because you can't charging battery!

tegranote7c is LTE version(Probably). Don't get confused.

Mainline (Grate)

Mainline kernel contains tegra114-tn7.dts.

It's partial worked linux-postmarketos-grate(5.11.0_rc4), but have some problems.
