背景#

我的设备是 410 wifi 棒，msm8916。最近发现了吃灰的它，发现内核还停留在 5.15，打算编译 6.6 的，于是打算备份，但鉴于起只能通过 9008 来备份整机，便有了这篇文章。

安装#

sudo apt install adb fastboot python3-dev python3-pip liblzma-dev git
sudo apt purge modemmanager

git clone https://github.com/bkerler/edl.git
cd edl
git submodule update --init --recursive

sudo cp Drivers/51-edl.rules /etc/udev/rules.d
sudo cp Drivers/50-android.rules /etc/udev/rules.d
# 重启 udev，不然无法识别设备
sudo udevadm control --reload-rules && sudo udevadm trigger

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
