[Epic 4G Android Development] BThomas22x:
IMPORTANT INFO

First I gotta give a shoutout to KellyLewis3985 because he's helped so much with modding the script to need less work for install, run faster, and have more programs work.

NEEDED!

Must Be ROOTED

1. Busybox (Preferrably the most updated version).

2. Superuser.

3. Android SDK (With knowledge on how to use it).

4. AndroidVNC (Search exactly that in the market. It will say "Android VNC Viewer").

5. Terminal Emulator (Also available in the market).

6. Patience when working with this.

UPDATE!!

Thanks to the persistance of urboy4mbx, we now know a little more information to get it working. While both KellyLewis3985 and myself were running custom ROMS, we didn't think about testing it for the stock build. So due to urboy4mbx's will to get this installed, we now know you MUST have a custom ROM installed. There's probably ways to get it to work on the stock build, but it's going to take a little more work. For now, make sure you have a custom ROM, download, and install the files, and if we got our scripts right, it should boot right up for you.

DOWNLOAD FILE!

NOTE: When you download this zip, you will need to extract it, and inside the extracted folder will be the folder "sdcard", DO NOT!! Place this entire folder in your "ubuntu" folder, simply open it and copy all the files from it to your "ubuntu" folder on your sd card.

Download File...

Ubuntu: Epic Edition v1.2 <---These are the files you will need to run Ubuntu. It will come with "bootlinux", "fsrw", "mountonly", "ubuntu.img", "ubuntu.sh", and "unionfs".

INSTRUCTIONS!

Options For Transferring Files To Phone

First Option...

Your first option of course is the easiest. Simply connect your phone to the computer, and mount your sd card. Once on the sd card, you are going to create a new folder labeled "ubuntu". Open this folder and transfer all the files from the downloaded zip file into this folder. After you have transferred the files to your "ubuntu" folder on the sd card, unmount the sd card, but leave the phone plugged in.

Second Option...

Your second option is "adb push". Here is the command for "adb push" if you cant, or don't feel like mounting your sd card.

First you need to create your destination folder. Do so with this set of commands.

cd C:/sdk/tools (Of course you might have your sdk folder in a different location, just cd to that location)

adb shell

su

cd /sdcard/

mkdir ubuntu

exit

Now you should be back at "C:/sdk/tools", or wherever you have your sdk folder located. Next, you push the files to your folder. In order to push the files, you first need to open the zip folder, and copy all the files into your tools subfolder in the sdk folder. Then push the files with this set of commands.

adb push bootlinux /sdcard/ubuntu

adb push fsrw /sdcard/ubuntu

adb push mountonly /sdcard/ubuntu

adb push ubuntu.sh /sdcard/ubuntu

adb push unionfs /sdcard/ubuntu

adb push ubuntu.img /sdcard/ubuntu

The "ubuntu.img" file may take a little longer, as it is the largest file that needs to be transferred.

NOTE: You cannot have your sd card mounted to use adb. You must be unmounted.

INSTALLATION

1. Ok, first thing you have to do is make sure you're still cd'd to "C:/sdk/tools". Now you need to type "adb shell". You will then most likely be prompted with the symbol "$". To continue, type "

su

" and the symbol should then change to a "#". NOTE!!!! After adb shell, YOU MUST TYPE "su", or the program will not boot!!!

2. Next you are going to cd into the Ubuntu folder on your sd card. (cd /sdcard/ubuntu) Once in, you're going to type the command "sh ./ubuntu.sh".

After that runs through, the next thing you're going to enter is "bootlinux". Once you get the prompt "root@localhost" you have successfully installed ubuntu on the Epic.

With this new update, there is no need to install any other files, as we have added them into the image file for you so it should do so automatically. If you have issues, let us know and we will try to fix it.

PREPARING YOUR VNC TO LOAD UBUNTU!

NOTE: There is no need to type this into your adb shell. This is for information purposes only, i've displayed the code and it's position at the bottom of this post along with screen shots to show you what it should look like.

With our new update, it's a lot easier to get everything up and running, but we don't have the capability of storing the vnc server to start every time we start up ubuntu, as it was causing issues. Until we get this issue fixed, you have to start the vnc server like this:

rm -rf /tmp/.X*

export USER=root

vncserver -geometry 1280x800 (Or whatever you would like your resolution to be. We have found this to be the nicest so far.)

Ok, at this point, everything should be set up to run.

NOTE: After the initial install of ubuntu on your phone, when you want to get it to start again, all you have to do is go into the terminal emulator, first type "su" to give it superuser permissions, then type "bootlinux", it will run through it's script and give you the "root@localhost" prompt. After you get that prompt, simply type the "rm -rf /tmp/.X*", "export USER=root", and "vncserver -geometry 1280x800" prompts and you can then start vnc again.

All the info you need for vnc will be as follows.

Nickname: "root"

Password: "ubuntu" (This is a set password, so it will be the same for everyone.)

Address: "localhost"

Port: "5901"

Change Log

Version 1.2

-Modified to make it ext4 compatible.

-Modified img to make it a little faster and more stable.

That's really all I had to do for this version, as it was working before.

Version 1.1

-Modified the scripts to run smoother, faster and use less memory while running.

-Added some custom wallpapers.

-Mozilla Firefox now works.

-Modified scripts to make Ubuntu more interactive.

-Modified the .img to install everything needed instead of you having to do it.

Issues

-Firefox randomly closes. Just reopen and restore.

-After using the vncserver Ubuntu doesn't truly shutdown without a reboot. Fix in progress.

-When wanting to start Ubuntu, after initial install, you have to go into the terminal emulator and type "su", then "bootlinux", allow that to complete giving you the "root@localhost" prompt. Then type "rm -rf /tmp/.X*", "export USER=root", and "vncserver -geometry 1280x800" to start the vnc server. After that you can go right into vnc and start Ubuntu up. We ARE currently working on a fix for this issue.

If you have any issues please post. Your input helps us make this better for you.

Here's a couple tricks we picked up.

1. You can use the arrow pad on your keyboard to direct the mouse.

2. If you long press on the screen and keep your finger on it, you can slide the mouse with your finger.

3. Long press on something, is a left click.

4. Double tap on something, is a right click.

5. To get symbols to appear, such as "-", you have to HOLD the function key while hitting the symbol.

And i'm sure there's more, but there's a couple for now.
