which Lenovo tricked me into getting in 012. Debian on the Lenovo 300e 2nd-gen arm64 Chromebook.
But because it's an Intel platform with a Celeron N4000 and 4G of LPDDR4-2400 you can install Debian on it, at least hypothetically.

NEC Chromebook Y1- Board Name
- PHASER360
- RW_LEGACY
Firmware- ✅
- UEFI Firmware
(Full ROM)- ✅
- WP Method
- CR50 (battery)
- Windows Notes
- Audio driver is paid.
- Linux Notes
- Supported
- MacOS Notes
- No MacOS support.
so this has been done before and this is thus largely a replication post, mirroring the chrultrabook documentation structure:

- Flashing Custom Firmware
- Installing an OS
- Conclusions
# Firmware
# Finding System Info
All of these I found in 012. Debian on the Lenovo 300e 2nd-gen arm64 Chromebook, sections Save me from chromium (chrome os (chromium os(?))) and Take me to hfbitland,- System Architecture
- x86_64
- Board Name
- PHASER360
- CPU Model and generation
- Intel(R) Celeron(R) N4000 CPU @ 1.10GHz and Geminilake
Why the model is in the uname I cannot tell you, but it is there. As seen above, it matches /proc/cpuinfo.
How to find your architecture and How to find your CPU model similarly recommend ctrl+alt+t to open the "decroded shell". This still doesn't do anything, and ctrl+alt+→ (not the arrow key) is required.
How to find your CPU model recommends cat /proc/cpuinfo | grep "model name". Why it's not grep "model name" /proc/cpuinfo is beyond me.
# Known Issues
# Firmware
GeminiLake: Legacy boot mode/alternative firmware menu works but does not show payload list
which is irrelevant.
# Enabling developer mode
has already been done in 012. Debian on the Lenovo 300e 2nd-gen arm64 Chromebook.
# Disabling write protect
- Tip
- You do not have to disable write protect if flashing RW_Legacy.
# Types of Firmware
# RW_LEGACY
- Warning
- The RW_LEGACY firmware is for users who want to dual-boot ChromeOS + Linux, or users who want to run Linux without having to open the device/disable the firmware write-protect (and are OK with the accompanying limitations).
# (UEFI) Full ROM
- Removes the developer mode boot ("OS verification is OFF") screen
- UEFI firmware contains updated EC firmware as well, which brings additional fixes on most Chromebooks (mainly keyboard related)
- Tip
- The (UEFI) Full ROM firmware is the best option for all users who no longer need/want to run ChromeOS (ie, want to run Linux/Windows/macOS exclusively), and who don't mind disabling write-protection on their device.
Unclear to me what "ie" means, but sign me up, brother. Here's hoping it also fixes the scandi keyboard.
# (Back to) Disabling write protect
# Disabling write protect via Battery
# Step 1: Open the device and disconnect the battery
The internal link from within google documentation is a 404. Obviously. Neither the fake nor the real Lenovo product page carry a manual of any sort, but a completely unrelated Lenovo page does, and it also has videos-as-in-37-second-MP4s that show where the latches are, because sexion "1020 Base cover assembly" of the manual says "Pry up latches and remove the base cover assembly." but doesn't show where the latches are. But the video does.
One of my screws was missing, but another was in a loose insert, and I only broke one tab! And another pile fell out from previous service.
# Step 2: Boot using AC power, and flash.
# Flashing Custom Firmware
- Run MrChromebox's firmware utility script within VT-2 (ctrl + alt + f2 (right arrow)).
- Type
cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.shand press Enter.
This is weird and borders on dangerous. Maybe? The website says
IMPORTANT
Due to recent changes in ChromeOS' security settings, you may need to use a new set of commands to run the Firmware Utility Script under ChromeOS. Running it under Linux can use the same old one-line command.
…
Also, you must execute these commands **as a normal/non-root user**. Running them as root will break things. DO NOT RUN 'SUDO SU' BEFORE RUNNING THE SCRIPT CMD BELOW.
To download and run this script under ChromeOS or Linux, from a terminal/shell type:
cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh
and press enter.
…
REALLY READ THIS: Under ChromeOS, starting with R117, this script must be run from a VT2 terminal (from login screen: CTRL+ALT+F2, login 'chronos'); it cannot be run from a crosh shell (CTRL+ALT+T when logged in) due to the removal of sudo, or from a crostini (penguin) terminal; […].
So: Are you supposed to run it as root under sudo? Run it as root straight from login? Or are you to not do that because it'll break your system? How is it gonna flash anything as non-root? If you log in as "chronos" are you supposed to drop the sudo it specs? Why does downstream Chrultrabook not comment on this at all and why does it not say which user you're supposed to log in as if it matters?
According to upstream this is all intentionally misleading,
and the purpose of the huge bizarre paragraph with a random user is to find a R/W mountpoint.
Just download it and run it as root
(copy it off the USB (sure, maybe under ~chronos, or mount -o remount,rw /), since it wants to exclusively mount it)
instead of this rigamarole.
I downloaded the thingy (which redirected me twice, last step at pisshub) onto removable media (unclear to me how you'd download it from the target system in a privacy-preserving way):
localhost login: root
Password: root
localhost ~ # mount -r /dev/sda /media/removable

MrChromebox Firmware Utility Script starting up
Downloading supporting files...
Error downloading one or more required files; cannot continue
The most natural question is "how does chromeos-setdevpasswd differ from passwd chronos"? Significantly:
The next-most natural question is "great.". Which isn't a question but "why the aren't there any errors?" is. Well, "MrChromebox's firmware utility script" is

which raises so many more questions (why are the curls supposed to fail silently? why are the three rms not one? &c. &c. in the trimmed parts),
but that's neither here nor there,

Which is possible due to the narrow flag vocabulary.
Some parts of flash_rwlegacy(), like the boot order, degrade gracefully, which is not what we want.
Similarly, downgrade_touchpad_fw(), which is meant to "offer to downgrade touchpad firmware on EVE" does the same.
But my laptop doesn't have "EVE" anywhere in the board name so no issue there.
All other curl uses hard-fail, and I turned around twice, for

The first time I tried this, it told me

Press Y (then enter) to disable software WP and reboot, or just press enter to skip and continue. Y
and, naturally, rebooted instantly, so I lost the transcript.

Install/Update UEFI Full ROM Firmware
IMPORTANT: flashing the firmware has the potential to brick your device,
requiring relatively inexpensive hardware and some technical knowledge to
recover.Not all boards can be tested prior to release, and even then slight
differences in hardware can lead to unforseen failures.
If you don't have the ability to recover from a bad flash, you're taking a risk.
You have been warned.
Also, flashing Full ROM firmware will remove your ability to run ChromeOS.
Do you wish to continue? [y/N] y
NOTICE: flashing your Chromebook is serious business.
To ensure recovery in case something goes wrong when flashing,
be sure to set the ccd capability 'FlashAP Always' using your
USB-C debug cable, otherwise recovery will involve disassembling
your device (which is very difficult in some cases).
If you wish to continue, type: 'I ACCEPT' and press enter.
I ACCEPT
NOTE: After flashing UEFI firmware, you will need to install a UEFI-compatible
OS; ChromeOS will no longer be bootable. See https://mrchromebox.tech/#faq
Press Y to continue or any other key to abort. Y
Connect the USB/SD device to store the firmware backup and press [Enter]
to continue. This is non-destructive, but it is best to ensure no other
USB/SD devices are connected.
Devices available:
1) Generic STORAGE_DEVICE (7.4 GB)

- Tip
- If you unplugged the battery to disable write protect, you can plug it back in now. All subsequent flashing won't require it from now on.
- UEFI
- It can take up to a minute for display to come up on first POST. Do not interrupt the first boot.
I'm not trying to be flipping the shit running with a cable plugged in, I plugged the battery back after rebooting and proof-booting d-i.
Yeah, it took about that long. But the updater explicitly says it won't boot ChromeOS anymore. So I held off until I had a d-i image.
# Installing an OS
# Known Issues
# Linux
- Debian 12 (Bookworm) needs a custom kernel.
No it doesn't. Pretty sure. No one wants to document what they mean by this. And I got spam-blocked on the forum for no reason.
And by that I mean this is not mentioned in the documentation, and not in one (screenshot), two, three, four, five posts about this from Chrultrabook authors, in a few cases while questioned directly. Do they even know why?
It turns out they do on the sixth attempt: the catchily-designated MR!768 – [x86] Various drivers for ChromeOS devices. A trivial analysis shows this actually wants a kernel at least 6.6.3-1, so at time of writing "current sid", but hopefully it'll be in backports later.
# Making a Bootable USB
# Flashing with dd (Linux/macOS)
I'm snidely avoiding comment on the bit where it specs dd but uses no flags that would make it do anything different than cp.
No syncing of any kind is criminal, though.
# Installing Linux
- Tip
- Only Linux kernel 6.4 or newer is supported.
It doesn't say why. Well – why? (See above.)
# Recommended Distributions
- Warning
- Debian versions older than Debian 12 (Bookworm) are not supported. Debian 12 (Bookworm) requires a custom kernel, the audio script will automatically install it for you.
- No the fuck it won't.
- Bookworm ships (at time of writing, from stable-security) 6.1.69-1, and the current d-i image's kernel is branded "6.1.66-1 (2023-12-09)". So it must work. (See above, again.)
If it were up to me, since this is just about some modules, this box would be
- Warning
- Debian versions older than Debian 12 (Bookworm) are not supported. Debian 12 (Bookworm) itself requires the backports kernel for full functionality.
- Danger
- On Debian 12 (Bookworm), the audio script will try to download an install a third-party kernel image. Answer N at the "Would you like the script to automatically install this kernel?" prompt!
But for now just install the sid kernel.
# Installation
- Install as you would on any other computer.
I'm assuming this means you can safely dump the whole /dev/mmcblk0? Which I had pause about, but clearly I oughtn't've'd.

(yeah there's two nested identical sexions)
- Danger
- Using AVS on a device with max98357a will blow your speakers. You have been warned.
this machine does have this device (apparently this is the check, and apparently this only affects output to the built-in speakers, and the "audio script" will disable it automatically, maybe), and:
$ grep -w CONFIG_SND_SOC_INTEL_AVS /boot/config-6.1.0-9-amd64 /boot/config-6.6.9-amd64 /boot/config-6.1.0-9-amd64:# CONFIG_SND_SOC_INTEL_AVS is not set /boot/config-6.6.9-amd64:CONFIG_SND_SOC_INTEL_AVS=mand, uncharacteristically, Linux doesn't spec what the modules are called, but it looks like snd-soc-avs, so booting the bookworm kernel is safe, but booting a later kernel wants
modprobe.blacklist=snd-soc-avsin the cmdline.So, with no contraindications, and a very peculiar sense of drip
(yes, that is a 4:3 EDK2 on an almost-16:9 monitor):
and I installed sid normally. ChromeOS used discard, so I added this to the mount options as well. Installing GRUB into the removable media path was not necessary. This yields #1060325.
Apparently, pressing alt and ˂ or ˃ (the arrow keys) cycles between the available VTs. This is useful because there are no function keys, and alt and ← or → (not the arrow keys) doesn't do anything.
I also persisted the blacklist after first boot and fixed the touchpad because the default decroded-ass no-tap-to-click behaviour is more infuriating than you'd think in a.d. 2023.

- Tip
- Install Chrultrabook Controller for fan controls, keyboard backlight controls, system information and more.
This machine has neither, and the "system information" in the screenshots appears to be the first three lines of dmesg.

# General QOL Fixes
- Run the audio script if you haven't already.
Heed the Danger, of course, if you installed Bookworm. The script checks if you have an audio daemon installed (in my case wireplumber), so make sure you do install it first. But, yes, this does work:

- Run the cros-keyboard-map script to remap top row FX keys.
This is actually much less annoying than the Home/End/PgUp/PgDn situation, which on normal small keyboards is Fn+←/→/↑/↓, but this is not mapped to alt+˂/˃/˄/˅ here, which sucks shit. No Delete is pretty bad as well. The top row is, accd'g to

XF86Sleep(🔒 is the Suspend Key and handled by logind by default; to see it you need to unmap it in /etc/systemd/logind.conf; I settled on

Super_LWhy 🔉/🔊 are on the keyboard when there are physical buttons for them (or vice versa) is beyond me, too.
The upstream instructions say to run install.sh, but on Debian that installs keyd off unchecked HEAD (which until three weeks ago dumped shit into /usr, and the installer checks for /usr/bin/keyd and will do it again; it continues to run unadorned
groupadd keydto add a system group!), first cloning it to no-where, and generates a config with# make vivaldi keys act like vivaldi keys when super isn't held for scancode in physmap: # Map zoom to f11 since most applications wont listen to zoom if vivaldi_scancode_to_keyd(scancode) == "zoom": mapping = "f11" else: mapping = vivaldi_scancode_to_keyd(scancode) config += f"{vivaldi_scancode_to_keyd(scancode)} = {mapping}\n" # map lock button to coffee config += "\nf13=coffee\nsleep=coffee\n"deadass

This would be excessive, but we can't actually even see
and the standard remapping facilities are insufficiently expressive anyway.
There's a 2024-01-04 ITP for keyd with no linked dsc, but it features on mentors.d.n, which, well, if I posted I could never show my face in public again (and it takes over a minute for one python program at 100% CPU on my big host, so there's no way it'd ever finish building on a shitty Celeron), but this is what mentors is for, so let's accept keyd is not in Debian:

[ids] 0001:0001 [main] f1 = back f2 = forward f3 = refresh f4 = f11 f5 = scale f6 = brightnessdown f7 = brightnessup f8 = mute f9 = volumedown f10 = volumeup back = back forward = forward refresh = refresh zoom = f11 scale = scale brightnessdown = brightnessdown brightnessup = brightnessup mute = mute volumedown = volumedown volumeup = volumeup f13=coffee sleep=coffee [meta] f1 = f1 f2 = f2 f3 = f3 f4 = f4 f5 = f5 f6 = f6 f7 = f7 f8 = f8 f9 = f9 f10 = f10 back = f1 forward = f2 refresh = f3 zoom = f4 scale = f5 brightnessdown = f6 brightnessup = f7 mute = f8 volumedown = f9 volumeup = f10 [alt] backspace = delete brightnessdown = kbdillumdown brightnessup = kbdillumup f6 = kbdillumdown f7 = kbdillumup [control] f5 = print scale = print [control+alt] backspace = C-A-delete(Rember that lines that start with "
f123 =" are no-ops, since the keyboard by default generates the special keys.)Yes: this has the ☕, but also identity-maps everything, and you unfuck it by holding 🔍 (the objectively-incorrect mode). Except
I feel like I could do better with
[ids] 0001:0001 [main] # ← back = f1 # → forward = f2 # ⟳ refresh = f3 # tableau zoom = f4 # fast rectangle scale = f5 # small ☀️ brightnessdown = f6 # ☀️ brightnessup = f7 # 🔇 mute = f8 # 🔉 volumedown = f9 # 🔊 volumeup = f10 # 🔒 sleep = delete # 🔍 remains as leftmeta [meta] # tableau zoom = print back = back forward = forward refresh = refresh scale = scale brightnessdown = brightnessdown brightnessup = brightnessup mute = mute volumedown = volumedown volumeup = volumeup sleep = sleep
, but also ←, →, and ⟳ are prime real estate for mapping something useful to. ctrl+alt+
With this, the optimal /etc/systemd/logind.conf becomes just the usual
[Login] HandlePowerKey=hibernateIt's also tempting to solve the Home/End/PgUp/PgDn situation here instead of with xmodmap, so appending this to the updated /etc/keyd/cros.conf works like one'd expect (but
[meta]is better for i3 usage; also note that you can't make another file and have it patch the big one, because at most one file can match each device):[alt] left = home right = end up = pageup down = pagedownI had to find out the hard way that keyd, by default, mangles Shift_R and Control_R into Shift_L and Control_L. Appending this is necessary to make them work correctly:
# https://github.com/rvaiya/keyd/issues/618 [main] rightcontrol = rightcontrol rightshift = rightshiftOverall, low value-add factor here. The quirks file is nice though. Let's hope it's upstreamed before it breaks, like upstream guarantees it will.

If you experience issues in applications such as Parsec, or […]Okay but that's so true though?
# Using Ectool
ectool is a utility that is used to interface with the ChromeOS Embedded Controller. It is used to communicate with the embedded controller from userspace and vice versa.Boy I sure hope to use this program to communicate with the embedded controller! I would love to communicate with the ChromeOS Embedded Controller through this program.
Also: no link and it's not in by that name in Debian. Is it the same one as /sbin/ectool from coreboot-utils? Unknowable.
# Conclusions
# pog moments
- normal computer
- normal debian just works
- overall a sensible walk-through
- privacy preserved (ChromeOS didn't ever see the network)
- fun bunny on POST
# cringe-ass nae-nae baby moments
- PXE-booting from a USB-C dongle doesn't work
- small patch and a few round-trips required to actually ensure privacy is preserved
- the recommended keyboard mapping is so bizarre I straight-up thought keyd was broken
- Chrultrabook stance is that users should give up their privacy to make following the guide more convenient (this is used as a justification for a mild editorial oddity and the impetus to retain it is stronger than to simplify the page)
- Chrultrabook and its upstreams appear allergic to actually documenting crucial security-sensitive and stated-as-device-bricking information in the text and actively avoid providing it when questioned
- this extends to Chrultrabook authors posting misinformation at least twice (screenshot), presumably because of this lack of documentation
- were I to guess, this is also probably why they consider users "not technical enough" 🤢 to follow a longer thing they may understand than a magical one-liner
- forum's fucking Discourse
- I ran out of words to put links on for the last one
- I liked her talk but elly threatened to ban me for
Shitting all over the non-profit project, documentation written by community and mentality "I know better than you" is exactly the kind of toxicity we don't want in our community.; one will do well to note we've interacted once on the forum and at most twice off the forum (of her accord) and both of those went fine. Odd behaviour, given that she's the one with the misinformation above, and, well, you've seen this post and you can click through to my mastussy thread and the forum post, none of these are particularly "shitting on", much less toxic. I don't even think I exhibit that mentality, really. Maybe this is a language barrier (we're both polish), seeing as I haven't gotten an actual warning or anything before (except for automatic Discourse bullshit), and another user with admin powers gladly unblocked me (also unprompted and of his own volition) more than once, well.# family guy funny moments

Most of the issues out-lined above have been forwarded. That is also the reason for most of them having been discovered.
A good bug report never goes unpunished.
