工具:
HyperOS
系统本体
进入Bootloader
Uotan工具箱中Wired Flash -> More Flash -> Xiaomi Script
选择Hyper_OS_1.1.5.0.VNXCNXM.BETA_安卓15/nabu_XiaomiPad5_OS1.1.5.0.VNXCNXM.BETA_15.0_By_mytiantian/flash_all.sh
,注意路径不能有空格
flash_all_except_storage.sh
可以不清除数据,也不会影响Linux
ROOT
(由于装Linux会清除userdata分区,Android侧会被还原,因此应该先装完Linux再继续)
adb install Magisk_27.0.apk
然后打开Magisk,它会自动修补并重启。
新内核
(要先完成ROOT才有TWRP)
(似乎装完之后会把UEFI覆盖掉,所以目前决定不做)
先备份boot:
Uotan工具箱 Format&Extract -> Extract -> PartName=boot_a -> Physical Part
然后推送内核包到设备:
adb push xxx.zip /sdcard
然后进入TWRP
Install -> 选择内核zip包 -> 滑动install
Linux
系统本体
进入Bootloader
lon-tool deploy ArchLinuxArmGnome.lni
WiFi问题
(由于未知bug,平板内置无线网卡发送功率被限制,导致网速非常慢,< 10 Mbps)
现象:
sudo dmesg
......

......
查到可能是由于无线监管域未正确配置,相关命令:
iw reg get # 查询无线监管域相关信息
sudo iw reg set CN # 设置无线监管域为CN
nmcli device wifi # 查询频道和带宽等信息
然而在我这台设备上设置无线监管域和频道都不起作用。
Workaround: 使用c转a转接头+USB无线网卡(见后文网卡驱动)
网卡驱动
(购买了绿联AX900无线网卡,支持Linux 6.x内核,但需要自己编译安装驱动)
依赖包
sudo pacman -S usbutils # for lsusb
sudo pacman -S xmlto kmod inetutils bc libelf git cpio perl tar xz # for kmod building
准备内核源码
平板安装的ArchLinux使用的是修改过的内核maverickjb/linux-6.1.10,即6.1.10-nabu
。
另:网卡驱动内核模块编译时使用的version magic
需要与内核保持一致才能被加载,通过置空LOCALVERSION
来防止版本号自动添加后缀+
。
git clone https://github.com/maverickjb/linux-6.1.10.git # fetch kernel source
cd linux-6.1.10
zcat /proc/config.gz > .config # use config of the running kernel
make ARCH=arm64 LOCALVERSION= oldconfig # make sure no new options
make ARCH=arm64 LOCALVERSION= modules_prepare -j7 # prepare the kernel for building module
make ARCH=arm64 LOCALVERSION= kernelrelease # check it, MUST be `6.1.10-nabu` !!!
构建并安装驱动
cd /path/to/aic8800_linux_driver
sudo bash install_setup.sh # prerequisite
cd drivers/aic8800
sudo ln -s /path/to/linux-6.1.10 /lib/modules/6.1.10-nabu/build # build with custom source
make -j7 # build the driver
ls aic_load_fw/aic_load_fw.ko && ls aic8800_fdrv/aic8800_fdrv.ko # check completion
sudo make install
然后插入无线网卡,ip a
应当显示新设备。
Trouble Shooting
深度修复
(出现HyperOS设置密码卡死的问题,怀疑TEE相关固件异常)
刷入小米平板5_恢复分区表专用包_A13/flash_all.sh
即可复原纯真MIUI14
安卓无法启动
(在UEFI Boot Menu中选择安卓后,重复进入UEFI的异常现象)
接入充电器,开机,进入UEFI,选择安卓,在黑屏且显示安卓标志之前拔掉充电器,随后成功进入安卓。
(玄学,原理不明)
GNOME无法启动
(Arch滚包后重启无法进入桌面)
发现是由于屏幕键盘模块在GNOME-47会崩溃 ref
sudo -u gdm dbus-run-session gsettings set org.gnome.desktop.a11y.applications screen-keyboard-enabled false
sudo systemctl restart gdm
