Following the building guide, I was able to compiled Android 7.1.2 from source and everything seems ok(showed successful on packing the update.img).
I dd on SD card but was unable to boot-up from it. It is still booting from EMMC.
At the moment I don 't have a USB C to A cable to try flashing on emmc to check if my built is fine.
Anybody has encountered before? TIA
I tried downloading the official Android image from VAMRS site and same issue, it doesn’t boot-up on SD card.
I just realized that both images(official and the one I compiled) are for EMMC upgrade only which is done through Maskrom mode.
Is there any way to make Android bootable from SD card?
