chromebook 轻度折腾,备份bios,恢复bios,激活。chrome book 打开开发者模式。
前言
chromebook 讲道理是个宝贝,可惜国内很难使用.(。→‿←。)。
为什么总是这样 o( ̄ヘ ̄o#).难受
chromebook 折腾 是一个系列的文章,后续会根据情况更新,有什么问题都可以留言,我会总结一下帮助其他人。
激活cheomebook
chromebook开机时需要登陆google账号进行设备激活。
然而由于神奇的力量,这一步可能有点问题 ( ´థ౪థ)σ
设置代理
chromebook开机后直接右下角链接wifi。wifi链接的地方有一个螺帽差不多的图片,点开他。
在里面就有设置的地方。没有图片,你们自己意淫一下吧乁( ◔ ౪◔)「
打开开发者模式
按住 Esc+F3 (那个类似圈圈的刷新按钮),然后按 Power,接着就会进入恢复模式。
接着,按 Ctrl+D,它会提示您确认进入开发者模式,您的数据会被清除。
再次按 Ctrl+D,或者等待 30 秒左右,系统会引导您进入开发者模式。
打开shell
chromeos是linux这个应该要清楚,那么作为linux肯定要有自己的shell。但是chrome自己也有一个shell。
这是两个shell,别搞混了。
chrome shell 只有一些基础的命令,也可以通过安装程序扩展
chrome shell 可以随便进入,但是linuxshell要 开发者模式才可以
进入chrome shell
按下面三个键就直接进入chrome shell了
CTRL + ALT + T
进入linux shell
在chrome shell 的命令行里输入 【shell】直接就进入linux shell了
Bios 备份及恢复
由于后期操作可能涉及bios 所以在这里提前说一下怎么备份恢复
首先我们把目录定位到下载文件夹
cd ~/Downloads
备份bios
sudo flashrom -r bios.bin
刷入bios
sudo flashrom -W bios.bin
备注
激活chromebook 需要登陆google 有些你懂的东西要自己准备
没有特别说明的话所有命令都是在chromebook 的shell里敲打的
EN:
Open developer mode
Press and hold Esc + F3 (the refresh button similar to the circle), and then press Power, then it will enter the recovery mode.
Next, press Ctrl + D, which will prompt you to confirm that you are in developer mode and your data will be cleared.
Press Ctrl + D again, or wait for about 30 seconds, the system will guide you into developer mode.
Open the shell
Chromeos is linux This should be clear, then as Linux certainly have their own shell. But chrome itself also has a shell.
This is two shell , do not get confused.
The chrome shell has only a few basic commands that can be extended by the installer
chrome shell can casually enter, but linuxshell developer model can be
into the chrome shell
Press the following three keys directly into the chrome shell
CTRL + ALT + T
Into the linux shell
In the chrome shell command line, enter the shell directly into the linux shell
Bios backup and recovery
As post-operation may involve bios so here to talk about how to backup and restore ahead of time
First of all, we will navigate to the directory to download the folder
cd ~ / Downloads
backup bios
sudo flashrom -r bios.bin
Brush into bios
sudo flashrom -W bios.bin
Remarks
Activate chromebook need to log google some things you know to prepare yourself
All commands are typed in the chromebook's shell without any special instructions

能不开机更新bios吗
真不开机的话需要编程器离线刷写
如果只是单纯的想刷回官方bios可以直接用chrome提供的恢复工具
不一定要编程器,你可以使用谷歌的调试线,通过另一台chromebook刷写
备份bios没问题,但是写入的时候老是失败。
sudo flashrom -w bios.bin

Uh oh. Erase/write failed. Checking if anything has changed.

Good, writing to the flash chip apparently didn't do anything.
你这是无法申请内存
我当时用的是ubuntu内置flashrom刷的,你可以试试
请问楼主默认的password是什么呢
早期是空的(直接回车即可),现在好像有了一些变化,可以做如下尝试:
-> admin
-> root
-> google密码
-> 利用chromeos-setdevpasswd设置密码
还可能是test0000
多谢指点
