I bought few days ago a N2+ with an eMMC pre-loaded with CE 9.2.7.
I wanted to upgrade it to 19.1.
I have a USB reader.
Just downloaded the image CoreELEC-Amlogic-ng.arm-19.1-Matrix-Odroid_N2.img.gz.
Used Etcher to flash the emmc and replaced the dtb.img in the root directory with g12b_s922x_odroid_n2.dtb
Then, the N2+ doesn’t boot at all. The blue led doesn’t flash.
Is there something else to do than just flashing the new image ? Is the bootloader on the hidden partition (seen from Windows) to be updated as well ?
