Also, has anyone figured out how to reliably work imaging and flashing the /system partition into this process?
It would save us loads of trouble if we had a solution.
Note the process must work with Android 7.1.1, and ideally uses an image generated by dd, as opposed to building one from scratch.
We've had problems making any modifications to /system -- It seems like with the stock bootloader/kernel/etc. it trips some type of security check and refuses to boot.
Does anyone have any more info on this? Is it simply impossible?
