GKI: Check-in local vendor modules and use db845c artifacts Move over to GKI completely. No more non-GKI kernel images. Pull Image.gz and platform (sdm845) modules from device/linaro/dragonaboard-kernel/android-5.4/. Local modules (panel and regulator) are copied to prebuilt-kernel/ directory. Local modules are installed in boot image ramdisk otherwise display panel/regulator fail to initialize and display doesn't come up. Local modules are built from following tree: https://github.com/pundiramit/linux/tree/android-5.4-modules The existing bootloader on PocoF1 does not support boot image header v2 yet. So check-in build/tasks/kernel.mk makefile which will concatenate Image.gz and sdm845-beryllium.dtb to generate bootable Image.gz-dtb at build time. Signed-off-by: Amit Pundir <pundiramit@gmail.com>
IMPORTANT NOTICE --> UNLOCKING AND ROOTING MAY VOID YOUR PHONE WARRANTY AND MAY BRICK YOUR DEVICE AS WELL. I'M NOT RESPONSIBLE FOR EITHER OF THAT.
Here is a reasonable guide to get you started on unlocking and rooting Poco F1 --> https://forum.xda-developers.com/poco-f1/how-to/xiaomi-poco-f1-unlock-bootloader-custom-t3839405
Just for the records I downloaded and installed following external packages to unlock and root my device-->
Also Dont forget to take a backup of your images from TWRP and copy them to your Host machine. It will come very handy. Believe me :)
repo init -u https://android.googlesource.com/platform/manifest -b master git clone git@github.com:pundiramit/android-local-manifests.git .repo/local_manifests repo sync -j$nproc source build/envsetup.sh lunch aosp_beryllium-userdebug make -j$nproc
NOTE: To get display working on PocoF1, we need supported Adreno firmware binaries, otherwise PocoF1 will not boot to UI.
Adreno binaries are shipped with non-distributable license,
hence I'm not shipping them in my build setup. You can
extract Adreno a630_* firmware binaries from a working
device build. I extracted mine from
lineage-16.0-20190612-nightly-beryllium-signed.zip ;)
Then copy the binaries to out vendor directory
i.e. out/target/product/aosp_beryllium/vendor/firmware,
and run "make -j$nproc" to create vendor.img again.
fastboot flash system system.img fastboot flash vendor vendor.img fastboot flash userdata userdata.img fastboot flash boot boot.img fastboot reboot
Use standard abootimg commands to update kernel (Image.gz-dtb) in boot.img and fastboot flash the updated boot.img.
My working kernel is hosted at -->
https://github.com/pundiramit/linux/tree/display (beryllium_defconfig).
Prepare bootable kernel image (Image.gz-dtb) by running -->
$ cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/sdm845-beryllium.dtb > arch/arm64/boot/Image.gz-dtb
