`sysrepart_1380_20.zip`のパーティションの処理が失敗する場合は、[公式img](https://developers.google.com/android/images)で初期化するといいかもしれません。
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
$ adb reboot-bootloader
|
|||
|
|
$ fastboot flash recovery twrp.img
|
|||
|
|
$ fastboot boot twrp.img
|
|||
|
|
|
|||
|
|
$ adb push sysrepart.zip /sdcard/
|
|||
|
|
# twrp -> install -> sysrepart
|
|||
|
|
|
|||
|
|
$ adb push lineageos.zip /sdcard/
|
|||
|
|
$ adb push opengaaps.zip /sdcard/
|
|||
|
|
# twrp -> install -> lineage, opengaaps
|

```

最近の権限管理はmagiskが定番のようです。
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ adb install magisk.apk
|
|||
|
|
# magiskでlineageのboot.imgにpatchを当てる
|
|||
|
|
|
|||
|
|
$ adb pull /sdcard/Downloads/magisk_patched.img
|
|||
|
|
$ adb reboot-bootloader
|
|||
|
|
$ fastboot flash boot magisk_patched.img
|
|||
|
|
```

### archlinux
|
|||
|
|
|
|||
|
|
archlinuxを使うには、archのimgを作成してchrootでアクセスします。大抵のコマンドはbusyboxを使います。
|
|||
|
|
|
|||
|
|
imgは[armv7](https://archlinuxarm.org/about/downloads)のarchを使って作成します。pacmanのmirrorも変わってきますので注意です。
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
$ export bbox=/data/adb/magisk/busybox
|
|||
|
|
$ export imgfile=/sdcard/linux/archlinux.img
|
|||
|
|
$ $bbox losetup -d /dev/block/loop255
|
|||
|
|
$ $bbox losetup /dev/block/loop255 $imgfile
|
|||
|
|
$ $bbox mount -o bind /sdcard $mnt/sdcard
|
|||
|
|
$ $bbox chroot $mnt /root/init.sh $(basename $imgfile)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```sh:init.sh
|
|||
|
|
export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin
|
|||
|
|
/bin/sshd
|
|||
|
|
```
