[G Tablet Android Development] scsione889:
This is a step by step guide to install ClockworkMod v08, a ROM of your choosing, Flash, and the Android Market fix. This guide assumes that there is no data on your device that is important to you. Back it up or prepare to lose it.

I do NOT accept responsibility for anything good, bad, or indifferent that may come from following this guide. This includes and is not limited to completely destroying your tablet. I highly recommend leaving your tablet plugged in while doing anything like this with your device. I have no idea what will happen if the battery dies in the middle of flashing a ROM (if anything…but better safe than sorry).

ALL THE FILES NEEDED FOR THIS GUIDE EXCEPT FOR THE ROM ITSELF CAN BE FOUND AT THE BOTTOM OF THIS GUIDE.

ROM XDA Pages (Look at these to pick what ROM you want to use.)

TnT Lite

VEGAn-Tab

CyanogenMod 7 (Gingerbread)

Notion Ink Adam ROM Port

You do NOT need to root your tablet to install a ROM on this device using this guide. All the after-market ROMs come pre-rooted so you don't need to root after installing either. :)

Part One – Install ClockworkMod v08

ClockworkMod is what will ultimately be used for all your flashing of ROMs, backing up, clearing cache, etc.

Step 1.

Download ClockworkMod v08 (This version has been found to work best...the newer version causes some issues with some ROMs.) There are two versions available; one for installing ClockworkMod from the internal memory, one for installing it from external memory (microSD/microSDHC card).

Step 2.

Unzip the file you chose (cwmod_internal.zip OR cwmod_microsd.zip) to the root folder on the storage option of your choice.

So, for example, if the storage option you chose has the drive letter “F:” assigned to it when hooked up to your computer, you would want it to look something like this…

A folder located at “F:\recovery”

A file located at “F:\update.zip”

Step 3.

Turn off your device.

Step 4.

Press the power button and the Volume+ button at the same time and release them when the Viewsonic splash screen pops up. You should see "Detect a recovery key pressed" pop up in the upper left corner of the screen.

Step 5.

Watch ClockworkMod install. This will not take long. Your tablet will reboot when installation is complete.

Step 6.

Enter ClockworkMod:

To get into ClockworkMod you need to shut down your device, then press the Power and Volume+ button (the same way you did to install ClockworkMod).

Navigating ClockworkMod: Vol+ and Vol- are to scroll up and down, the home button selects an option, and the back button backs up.

Step 7.

Re-Partition your Tablet:

In order to make sure the Android Market works correctly after installing any ROM, we must re-partition the device.

Select the advanced option at the bottom of the ClockworkMod menu, then go to “partition SD card”, for the first option select 2048, and for the second option select 0. This erases data on your tablet. Be prepared.

Part Two – Install a ROM.

A ROM (explained in very basic terms) is like Windows on your computer (assuming you’re not running Linux or Mac OS). Each ROM contains a customized version of Android that comes packaged with software, themes, and everything else you actually see when the device powers up. You install any additional apps you would like to use after installing the ROM. Beware, ROMs are device specific. You cannot reliably install ROMs designed for another device.

Step 1.

Now that your device is essentially empty, we need to be able to put files on it. ClockworkMod can do this for us. Connect your tablet’s USB cable from your tablet to your computer. Go to the ClockworkMod main menu, then navigate down to “mounts and storage”, and then select “mount USB storage”. The tablet’s internal storage will then be accessible from your computer. You will want to open it, and create a folder called “ROMs”.

Step 2.

Download whatever ROM you want to use. The links to the ROMs are located above. Click on the link to see what that ROM looks like. The most popular ROMs for this device are TnT Lite and VEGAn Tab.

Step 3.

Copy whatever ROM you wish to install (it should be a .zip file) to the ROMs folder on your tablet. (Leave it zipped, Clockwork will install it from the .zip file as is).

Note: If the ROM you downloaded has multiple files, look for the one named “update.zip” and rename it to whatever you want (something to help you differentiate it from other ROMs), then copy that to the tablet. If an “update.zip” doesn’t exist, and you’re lost…read through that ROM’s thread and see if anybody else asked about it…if not then you probably should (on that ROM’s thread…each one is different).

Step 4.

Turn off your device.

Step 5.

Boot into ClockworkMod. (Press the power button and the volume+ button at the same time until the Viewsonic splash screen pops up, release, then you should see “Detect a recovery key pressed”. After that it will think for a few seconds and then it should boot into ClockworkMod)

Step 6.

Stand up and do a dance. Sitting too long isn't good for you.

Step 7.

Back up to the main menu, then navigate down to “mounts and storage”. When that is highlighted press the home button to select it.

Step 8.

We want to mount “/system” and “/data”.

The goal is to see the following:

“unmount/system”

and,

“unmount/data”

If either one says “mount” instead of “unmount” you need to navigate to that line and press the home button to mount it.

Step 9.

This is the step that we actually flash the ROM in.

From the ClockworkMod main menu, navigate down to “install zip from sdcard” and press the home button to select that option at the menu.

Then, navigate to “choose zip from sdcard” and press the home button to select that option.

Navigate to the line that reads “ROMs” and press the home button to select that option.

Navigate to the line that reads whatever .zip file you wish to install and press the home button to select that option.

Navigate to the line that reads “Yes – Install yourzipfile.zip” and press the home button to select that option.

You will now see it do its thing. When complete you will see something along the lines of “install zip from sdcard complete” at the bottom of the screen.

Press the back arrow over and over again until you get to the Clockwork’s main menu.

Step 10.

Here is where we prepare the system to run the new ROM.

Navigate down to “mounts and storage”, select it, and mount “/system” and “/data” again as in steps 7 and 8.

Back up to Clockwork’s main menu.

Navigate to “wipe data/factory reset”, select it. Navigate down to “Yes – delete all user data”, and select it to wipe out user data and all the cache. (You need to do this for the new ROM to function correctly)

Now, navigate to the top option “reboot system now” and select it. Your tablet will now reboot. It may take up to 15 minutes to start up the first time as it rebuilds the user data and cache for this ROM.

If your tablet boots to UID errors, or has force closes (known to fix a few of them)…

Press and hold the power button to shut the device down. Boot back into Clockwork. Select the advanced option at the bottom, and then go to “Fix Permissions”. Afterwards, back out to the main menu, then select “reboot system now”. If that is unsuccessful then boot back into Clockwork and redo steps 7-10.

Part Three – Install Flash and fix Android Market

This is needed to view websites with Flash based content, and to download apps from the market. (Fairly obvious, I know, but just in case somebody doesn't know.) Log in/set up your Google Account before trying the market fix (steps vary on the ROM you are using…in most cases you can access the web accounts by opening the Contacts app, pressing the menu button (the one above the back button), and selecting accounts).

Step 1.

Download “Adobe Flash Player 10.1.120.1.apk” which you will find attached at the bottom of this post and save it on your tablet (I recommend creating a separate folder to save .apk files in).

Step 2.

On your tablet open up whatever file explorer comes pre-installed with the ROM you’ve selected. In there, open up where you saved your .apk, then select Adobe Flash Player, and follow the on screen instructions to finish installing that.

Step 3.

Open the Market app. Once it loads close it (press the home button).

Step 4.

Go into Settings - Applications - Manage Applications - Market - Clear CACHE - Force Stop

(For TnT/TnT Lite... Settings - Applications - System Applications)

Step 5.

Press back once - Google Services Framework - Clear DATA - Force Stop

Step 6.

Go back to your home screen and open up the market. You should get an error. If not, redo steps 4 and 5 until you do.

Step 7.

Reboot your device. After it starts back up let it sit for a minute or two to let things in the operating system normalize. Open the Market. Reboot your device.

Step 8.

Open the market again and enjoy. You should now have Flash and the Android Market.

This is the Titanium Backup method. Thanks to roebeet, xguntherc, and KorbenD.

Part Four – Show your appreciation! (First, be sure to play some Angry Birds) :P

I encourage everybody to take the time to send a kind message, or a small donation, to everybody that helped make this device what it is. This is not me saying "HEY HEY DONATE TO ME!!!!"...like some developers for other devices do. I just feel like the great ROM developers for this device don't get the credit they deserve, so please at least send them a quick thank you note. Keep in mind that ROMs, utilities, and yes (even guides), take a considerable amount of time to plan, compile, test, fix, and distribute.

With the following link you can donate as much or as little as you would like to me (even a dollar helps). Thanks and enjoy your tablet!
