    刷机 + TWRP + Magisk

    参考：https://zhuanlan.zhihu.com/p/147299441

    ROM

    • Google FactoryImage Android 7 ~ 10
    • LineageOS Android 7 ~ 11

    TWRP

    可能是因为AB分区等问题，实际测试不能高于 3.3.0 版本

    • twrp-3.3.0-0-sailfish.img
    • twrp-pixel-installer-sailfish-3.3.0-0.zip

    刷机步骤

    adb reboot bootloader
# flash-all

    刷入永久TWRP + Magisk

    这些步骤一气呵成，中间不要重启进系统
    如果重启后无限循环进入TWRP，点击 Advanced → Fix Recovery Bootloop 滑动 Swipe to Confirm 修复TWRP循环，重启即可

    adb reboot bootloader
fastboot boot twrp-3.3.0-0-sailfish.img
adb sideload twrp-pixel-installer-sailfish-3.3.0-0.zip
adb sideload magisk.zip

    NTP 时间校准

    参考：https://zhuanlan.zhihu.com/p/145266379
    修改后需要重启才生效

    # apple
adb shell "settings put global ntp_server time.apple.com"
# aliyun
adb shell "settings put global ntp_server ntp1.aliyun.com"

    永久获取 adb root

    參考：

    参考以上教程，安卓10未成功，还会导致开发者选项打不开，暂时先不研究了…

    系统分区问题（OpenGApps）

    系统分区大小一般是出厂设定的，官方的线刷包会修改分区为默认值，第三方的包可能不会去改分区。
    参考教程：

    刷入OpenGApps失败 Error 70

    adb pull /sdcard/open_gapps_log.txt

INSTALLATION FAILURE: Your device does not have sufficient space available in
the system partition to install this GApps package as currently configured.
You will need to switch to a smaller GApps package or use gapps-config to
reduce the installed size.

NOTE: The Stock/AOSP Dialer is not available on your
ROM (anymore), the Google equivalent will not be removed.
!!! WARNING !!! - Duplicate files were found between your ROM and this GApps
package. This is likely due to your ROM's dev including Google proprietary
files in the ROM. The duplicate files are shown in the log portion below.

    格式化分区

    无需格式化，命令先留着

    mke2fs -t ext4 /dev/block/sda33
mke2fs -t ext4 /dev/block/sda34
mke2fs -t ext4 /dev/block/sda35

    反复折腾了N遍，最终发现，每次不管是刷官方还是三方系统，分区都会重置为2G。
    应该先刷好系统在修改分区，重启或者格式化data再重启
    太新版本的OpenGApps刷进去可能启动不了，根据机型情况尝试不同版本

    • 临时进TWRP
    • 刷ROM
    • 重启到fastboot，临时进入TWRP
    • 刷OpenGApps（system分区够用）
    • 刷OpenGApps（system分区不够）
      • 分区扩容（首次扩容执行全部代码，以后每次执行第二段resize2fs）
      • 重启到fastboot，临时进入TWRP
      • 刷OpenGapps
    • 重启
    • 临时进TWRP
    • 刷永久TWRP + Magisk
    • 重启
