sudo apt install -y abootimg device-tree-compiler

A few devices, like the POCO F1, require externally powered OTG cables to function. So, make sure to connect an external power source to the OTG cable.

Below are the steps for the POCO F1 EBBG variant. You can identify the variant by running the following command: cat /proc/cmdline If your device uses A/B partitioning, you can use the qbootctl tool to determine the active partition.

# Create a temporary working directory
TMPDIR=$(mktemp -d) && cd $TMPDIR

# Copy the dtb file of your device (eg berylium-ebbg for POCO F1 EBBG Variant)
cp /usr/lib/linux-image-$(linux-version list | tail -1)/qcom/sdm845-xiaomi-beryllium-ebbg.dtb orig.dtb

# Decompile/Convert dtb to dts file and change the dr_mode value
dtc -o tmp.dts orig.dtb
sed -i 's/dr_mode = "peripheral"/dr_mode = "host"/' tmp.dts

# Recompile the modified dts file to dtb
dtc -o host.dtb tmp.dts

# Merge kernel and modified dtb file into one file
cat /boot/vmlinuz-$(linux-version list | tail -1) host.dtb > kernel_dtb

# Get the flashed boot.img from boot partition
dd if=/dev/disk/by-partlabel/boot of=boot.img

# Update the kernel in boot.img file
abootimg -u boot.img -k kernel_dtb

# Flash the updated boot.img
dd if=boot.img of=/dev/disk/by-partlabel/boot

After performing above steps successfully, reboot your device.
