Acer Chromebox cxi4

I have an acer chromebox cxi4 computer. I want to cancel Chromeos and install Windows 10. I connected the 2 holes on the motherboard to each other. How do I know if I am a developer? Ctrl + alt + f2 does not work on the chrome installation screen. Because Linux is not seen installed in Chrome OS. Can you help me?

2

the directions on the chrultrabook docs and my site are very clear. The order in which to do things is explicit.

If youā€™re asking ā€˜how do I know if Iā€™m in developer modeā€™ then you need to re-read the documentation. If you think Linux inside of ChromeOS has any relationship to any of this, then you havenā€™t read the documentation.

3

Canā€™t you help me a little bit, master, I connected the dots on the motherboard, I activate the developer mode, when Chromeos is opened, it says ā€œThis device is managed by TPā€¦ā€ I cannot open a terminal, so I need to install bios.

4

if you canā€™t open a terminal, then youā€™re not in developer mode.

If you have a managed device, none of the instructions apply

is that not clear from the documentation?

5

I read the documents using translation. My English is weak. Is it not possible to turn on developer mode on my device and install Windows 10? Master

6

not if the device is managed and developer mode is locked out.

In that case, you must flash the firmware manually using a USB programmer, treating the device as if it were bricked

7

Are you talking about removing and programming the eeprom on the motherboard with an eprom programmer?

8

no, Iā€™m talking about flashing the chip in-place using a chip-clip as per the documentation (assuming the device has a clippable chip)

9

Ok, I have that file, where can I find it to program?

10

I donā€™t understand your question

11

USB I have the programmer. Where can I find the file that I will upload to the eprom?

12

the unbricking documentation on my site tells you how to get the file

13

Can I install Eprom on Windows 10?

14

you can flash the firmware image using software under Windows, however I do not recommend this:

  • you need linux to run the tools to extract parts of the stock firmware and inject them into the UEFI firmware before flashing
  • you really should only be flashing the ā€˜biosā€™ region of the chip, and not the entire thing

the instructions on my site tell you how to do this from Linux. I recommend using them. If you donā€™t, then I canā€™t help as Iā€™m not a Windows user or dev.

15

Iā€™ve never used Linux either, so I asked if I could do it from Windows.

16

I sometimes make a remote connection to install phone software. Can you make a remote connection to help me? You have explained it in detail on your site for my Chromebox device, but I am unfamiliar with Linux and I am very confused. I would be grateful if you could do it with a remote connection if possible.

17

then ask questions about the parts you are confused, so we can improve the documentation

18

Before I start flashing the bios of my Acer Chromebox CXI4 model computer with ch341a, I would like to ask some questions that come to my mind.
1-NOTE
You donā€™t need to do this if flashing a stock firmware backup created by the Firmware Utility Script; that image already contains the VPD.
I want to protect vpd and hwid.
2. I donā€™t understand the Shellball ROM and UEFI full ROM issue. Will my machine have UEFI full ROM? I downloaded a full ROM. Should I inject the VPD and HWID into it?
The rom I downloaded: coreboot_edk2-kaisa-mrchromebox_20240914.rom

19

there are 3 images you can flash for any given board:

  1. a stock backup made by the script (or made manually)
  2. a shellball image extracted from a recovery USB
  3. a UEFI Full ROM image

#1 has the VPD/HWID in it, #2/#3 do not, so for those you need to persist the VPD/HWID as per the instructions.

When I want to flash the coreboot_edk2-kaisa-mrchromebox_20240914.rom file
