How to unlock and root Poco F1?

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-->

• miflash_unlock-en-3.3.525.23.zip (MS Windows only tool for unlocking)
• twrp-3.3.0-0-beryllium.img (Recovery)
• beryllium-9.6.10-9.0-vendor-firmware.zip (LineageOS dependency)
• lineage-16.0-20190612-nightly-beryllium-signed.zip
• Magisk-v19.3.zip (Root)
• MagiskManager-v7.2.0.apk

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 :)

How to build and flash beryllium AOSP images?

• Download source and build AOSP images for Poco F1 (Beryllium) -->

mkdir aosp-repo
cd aosp-repo
repo init -u https://android.googlesource.com/platform/manifest -b master
git clone https://github.com/pundiramit/android-local-manifests.git .repo/local_manifests -b master
repo sync -j$nproc
source build/envsetup.sh
lunch beryllium-userdebug
make -j$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/beryllium/vendor/firmware,
    and run "make -j$nproc" to create vendor.img again.

• Flash and boot AOSP images -->

fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash userdata userdata.img
fastboot flash boot boot.img
fastboot reboot

How to run custom kernels?

• Run following commands to clone the kernel source and prebuilt Android toolchains and build scripts:

mkdir kernel-repo
cd kernel-repo
repo init -u https://android.googlesource.com/kernel/manifest -b common-android-mainline
git clone git@github.com:pundiramit/android-local-manifests.git .repo/local_manifests -b kernel
repo sync -j$nproc
BUILD_CONFIG=beryllium/build.config.beryllium ./build/build.sh

• Delete all objects in aosp-repo/device/xiaomi/beryllium/prebuilt-kernel/android-mainline/ then copy build artifacts from kernel-repo/out/beryllium-android-mainline/dist/ to aosp-repo/device/xiaomi/beryllium/prebuilt-kernel/android-mainline/ build AOSP images again.

cd aosp-repo
source build/envsetup.sh
lunch beryllium-userdebug
make TARGET_KERNEL_USE=mainline -j$nproc

• Now reflash the images as above and boot with your custom kernel.

  NOTE:

  By default the above instructions will sync/download
  beryllium-android-mainline branch to kernel-repo/beryllium directory.
  If you want to reproduce android12-5.4 or GKI build then checkout
  common-android12-5.4 repo manifest and beryllium-android-5.4 branch instead.

• LEDs and Brightness Control
• Camera
• Modem / RIL / Voice Call
