重启前
adb shell getprop | grep slot_suffix
手动重启以后,通知栏会出现"Finishing system update..."字样
adb shell getprop | grep slot_suffix
系统成功由slot A切换到slot B
环境问题
执行脚本出现如下错误:ImportError: No module named google.protobu update_device.py以及相关脚本都是使用python2编写,如果使用python3需要大量改动。需要安装3.17.3这个是python2支持的protobuf最后一个版本,不然会出现各种编译的问题。
sudo pip install protobuf==3.17.3 |
