米8的降级之旅
趁着刚刷完还有点记忆赶紧记录一下!
起因:之前 Google Map 老是闪退不以为意,最近发现 Google Photos 等一系列 Google 系产品也无法正常使用。刚开始还以为是网络或者版本问题,再三确认网络顺畅并且无论什么版本都无法使用。折腾到放弃,于是去网上搜了搜 MIUI 12.5 + Google, 结果收获一大堆吐槽,说是这个版本后取消对旧手机的支持了。怎么办呢?
方法一:买新手机。我一般只有在手机卡得不行了或是电池不行才决定换手机,现在的手机尽管用了好几年但性能耗电量依然不错,另外在国内买能支持 Google 服务的手机还得调研很久,即将出国留给我的时间不多了。
方法二:给手机降级。刚开始我还以为恢复出厂设置可以直接降到刚买手机时的版本,但事实上恢复出厂设置后系统等级不变,只能通过刷机降级。
刷机这个词并不陌生,但真正干还是第一次,所以还是提心吊胆的,所幸整个过程很顺利。下面记录一下整个过程,首先提一下背景。
我的设备信息:手机是小米8,电脑是 mac,装有 windows 的虚拟机。
准备刷机工具和线刷包:
- 谷歌提供的工具包 直接下载即可
- 好心网友们整理的ROM仓库 根据手机型号,刷机方式,版本选择合适的包下载
下载好这两个东西后,把它们并到一起。
小米刷机有两种,一种是线刷,一种是卡刷,我使用的是前者。(在 b 站看到有人通过瞒天过海降级成功,即升级过程中把安装包放到某个路径下,替换掉升级的安装包,这种方法看上去很简单,但感觉风险蛮大的,我就只能看看惊呼一句牛逼)
线刷的第一步,就是解锁 Bootloader。怎么解锁很简单,官方也有工具可供下载,但这个工具只能在 windows 上进行。一开始我不想用虚拟机,但网上推荐的 mac 可用的工具,比如 MiUnlockTool 或是 XiaoMiTool V2 都不可用了,所以最后还是上虚拟机了。
下载好解锁的压缩包解压后,点击一个带有 unlock 的 exe 文件即可打开 Unlock Tool,界面样式如下图所示:
使用 USB 连接你的手机和电脑,注意先把左下角的账号给登录了(我一开始就关机开 Fastboot 模式,结果登录账号需要手机验证码,又重开机重关机 🤦♀️)
登录账号后在将手机关机,长按开机键和音量调低键进入 Fastboot 模式(也可以通过终端输入 adb reboot bootloader
进入)
打开电脑的终端,进入下载文件的目录后输入:
$ adb devices

本以为要等很久,没想到很快就好了。就这样,享受你的降级手机吧~
好心网友整理的适合米 8 降级的线刷包最高是 V12.0.4 版本,所以我就刷了这个版本。之后我尝试用了酷安 xkeyC 大大开发的 X Google Installer 安装三件套,安装完后启动无压力,再也不会出现按了半天没有反应的现象。12.0 这一系列的版本应该都是 OK 的。
温馨提醒:刷机前备份一定要谨慎谨慎再谨慎!我删得太卖力,一不小心把 Tasker 和 Autojs 都直接卸载了,曾经写的自动化脚本就全没了 😭
有舍也有得。除去了微信庞大的聊天记录以及多年不用的 app 后,曾经存储空间占用率 75%,现在只有 10% 不到,非常清爽。趁着全新系统好好调教一下手机,我发现原生的浏览器也没有那么不堪,把广告入口都关闭也还算是清爽;每一次初开应用认真设置权限,做到非必要不给权限;下载个李跳跳远离各种开屏广告;微信聊天记录日日清理,能退的群都退了;管理好 app 的密码,让自己有更好的掌控感;应用断舍离,做到非必要不下载,可以用小程序代替就不下载应用…这样一番处理后,玩手机的体验也似乎改善了不少呢!
祝每一个刷机的人都能成功!
