Miscellaneous info

Creating empty dtbo image

Simply erasing the dtbo partition is not enough to make mainline boot on this phone. In order to make it boot we need to sign an empty dtbo image with avbtool:

$ dd if=/dev/zero of=empty_dtbo.img count=1
$ avbtool add_hash_footer --partition_name dtbo --partition_size 16777216 --image empty_dtbo.img
$ heimdall flash --DTBO empty_dtbo.img

If the phone still boots to the blue download screen, make sure stock vbmeta is flashed.

simplefb

Since at least the "SM Gen 4"/Waipio era, abl checks if a node named exactly /reserved-memory/splash_region exists in the device tree. If not, it will disable the display hardware:

ret = FdtPathOffset (fdt, "/reserved-memory/splash_region");
if (ret < 0) {
  DEBUG ((EFI_D_WARN, "Splash region not found in device tree, " \
                      "powering down the display and controller\n"));

Command to create boot.img

$ make O=output-e3q ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc) defconfig sm8650.config
$ make O=output-e3q ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc) &&
rm -f output-e3q/arch/arm64/boot/Image-dtb output-e3q/arch/arm64/boot/boot.img &&
