For anyone else who might run into this issue in future, here's what I did to fix it:
- Get into Download mode. To do so, power off the device and hook it up to a power source. You'll then see the Android One boot screen followed by the charging icon. At the charging icon, press vol DN+power for 5s. Then you're in Download mode. You'll know when it says 'Download mode' on the Android One boot screen.
- Now that you're in Download mode, your device can be recognised by fastboot (but not adb). Send 'fastboot oem HALT'. Then disconnect the cable, which will cut power to the device. Plug your device into power again (AC) where it'll show the charging animation again. Press vol UP+power until you see the 'No command' screen. Once at this screen, hold power and push vol UP. You're then at the recovery screen.
- adb will now work. sideload O (213B '00WW' package) to the device and perform a data wipe (optional, but I did it anyway). Send the package to the device via adb sideload.
- Reboot the device once you're done sideloading O.

印象里 VMware 也是往驱动里加一堆虚拟网卡的货，冲突不奇怪……

5s 升级后没有感觉比手里 iPhone x 慢……

京东不绑定银行卡也能付钱么……

你是联通的第一个用户么……

这货就觉得图标太丑……

我觉得阿里系的应用在后台挖矿……

@jasonyang9 会

远程登录用不同账号

一切正常，看起来是规则没设置好

@hymzhek 刷国际版就是回退 8.1 ……

@cameo 现在培训班学费 4，5 万，学生根本不差这个钱……😄

在口袋里误触了屏幕摄像头会不会把裤子顶破？

Mac 没有+1 ……会不会是中国特供版？

@hymzhek 不了解……

@paparika 当然会有一部分拿去升级举世闻名的 GFW，然后我们再花钱翻过去

@hymzhek 这种操作一般都可逆，但是需要自己找国行固件。我只有一张卡，没试过双 4G，也没试过电信 4G，如果你试过了求分享结果


@uppu 报错不是一开始就有的，我用 play store 下载了五个应用才开始报错，什么连接失败，杀了重进都没用，无论如何都再也装不了其他软件了，只能把 play store 卸载重装，安卓 8.1
