Is there any way how to boot this build completely off SD card (preferred) or USB flash? Got older G18 box with completely dead NAND. Even attempt to format data partition during normal recovery is enough to freeze kernel. I managed to install EmbER in the past (probably because it clears NAND before installing) but now it doesn't work anymore. And this build will be much better and newer anyway.
I will try making SD card with two partitions: 1. fat32 with kernel and system and 2. ext4 with valid DATA label.
But I think I have already tried this before and while I could load the kernel, it failed to find and use system partition.
