[Guide][ARM now supported] Android development/debugging on ChromeOS - ADB & fastboot - Chromebooks

[Guide][ARM now supported] Android development/debugging on ChromeOS - ADB & fastboot
What you need to know before we begin:
ChromeOS (Or Chromium OS if you installed it on a non-chromebook) is based on Unix, and you can access a terminal with button combinations. This part of the guide is easy, but if I can get apt-get working, that's where it gets really complex.
What you'll need
A computer running ChromeOS/Chromium OS
An internet connection on it, or the files on a USB drive (and you to copy them to Downloads)
A little Linux knowledge
Some patience
1.) Download the correct files for system:
ChromeOS/ChromiumOS on an x86 based PC
ChromeOS on an ARM based PC
2.) When the zip has downloaded, extract it so both the adb and fastboot files are in the Downloads folder
3.) It's now time to access the terminal mode. It might be a good idea to get this guide on a phone or some other device so you don't have to switch out at any time.
If you're using a chromebook or an official chromeOS build, you need to access developer mode. Note: this will wipe all your data for security reasons. Full info is here: Chromium Project: Developer mode
4.) Press Ctrl-Alt-F2 on your keyboard, and the whole screen will be a terminal. Read the info at the top, and then login
NOTE: If you're using Chromium OS vanilla builds, the username and password are as follows:
Code:
User: chronos
Pass: facepunch
5.) You now have a localhost terminal, with no root permissions.
6.) Run this code, to locate the location of your Downloads folder:
Code:
ls /home
7.) Mount the filesystem as follows:
Code:
mount -o remount,rw /
8.) Using the name other than "root" and "user", run these commands:
Code:
cp /home/<name>/user/Downloads/adb /sbin/adb
For example, the Chromium one would be:
Code:
cp /home/chronos/user/Downloads/adb /sbin/adb
Repeat for Fastboot (replace "adb" with "fastboot" without the quotes)
9.) Test that it has worked by running:
Code:
adb
It should result in adb working
10.) You're done, adb and fastboot should work. You might need to reboot in some cases for it to work fully
11.) For more stuff, like Java and ant, wait a while until I work out how to get apt-get installed from dpkg

Once more, just in case

Whenever I go to check my path I get this response:
"cat: /usr/local/bin:/usr/bin:/bin:/opt/bin:/home/chronos/user/Downloads/android-sdk-linux/platform-tools: no such file or directory"
Help?

That is perfectly normal, every Linux based thing says no file or directory after the path to my knowledge

And so it seems! Now it appears that any adb command returns a "Permission denied" message. Ideas?
Update: Same response for fastboot commands.

Try this:
Code:
cd /home/chronos/user/Downloads/android-sdk-linux/platform-tools
chmod 755 adb
chmod 755 fastboot
Then exit back to the login screen on the terminal, login again and try running adb

Still no dice
I'm starting to lose hope. I just keep getting "permission denied."
I thought maybe trying this would do the trick but still no response.
Code:
sudo ./adb devices
[code]
P.S. Guess I should mention that running just adb returns command not found, so I've been using ./adb. Maybe I just don't know what the hell I'm doing but I just can't get it to work.

---

Hmmm. Well, The SDKx86 (87mb) that were in the instructions so, I downloaded the ADT (399mb) instead, just a hint.

---

Is there a specific branch that is required to be on in chromeos in order for terminal to act correctly? I never get any chance to login once i get into the "crosh" terminal.

Instead of doing
Code:
cat $PATH
you should do
Code:
echo $PATH
The cat command is trying to concatenate a file with the name of your full path, which obviously doesn't exist. echo tells you the value of the $PATH variable, which is what you're actually trying to do.

I was trying to get this to work on my Chromebook Samsung Series 5 550
Furst thing I noticed was the absence of an f2 key - tried a usb keyboard no joy
I assume what I am trying to launch is Shell which can only be accessed with a Chrome OS device in developer mode. I really want to get this working so I will try activating developer mode and report back.
Update:
So Developer Mode resets and wipes your device (doh!) back to Step 1
Update 2: (Dev Mode activated function key labelled as "->" works as f2 and launches shell successfully"
Has anyone got this working? I noticed that the folder coming out of the SDK zip is called "sdk" but all the commands listed in the guide use "android-sdk-linux"
I used "sdk" and just get the Permission Denied issue even after chmod on adb

---

Will this work on the Samsung Series 3 with the ARM processor?

Supposedly pulling the adb binary from an android device (/system/bin/adb) and using that would work. Don't know about fastboot though

I had the same problems. And just stopped trying about 2 days of trying to figure it out.

I was able to find a version of adb compiled for ARM but it was from an older version which made it a no go on my Nexus 4 (4.2.2 requires updated adb to work with the new security enhancements built in).

---

I tried it on my Series 5 550 chromebook. Can't seem to get it to work.
I do all the commands and it shows up in echo $PATH but then when i try adb anything it says permission denied. I do the chmod 755 and still permission denied.
i tried to exit back to the login and then the folder wasn't in the echo path anymore. adb not working either. I tried rebooting chromebook and it wasnt there either.

---

Would it be cheating to get it running with crouton? Because I did get that done.

yeah i've been having the same issue with my samsung 5 series chromebook. "permission denied" and all that. But on the fun side, i learned if you want to really make your chromebook bug-out; type cat adb whilst in /platform-tools.
