[G Tablet General] slayer0017:
Hi All,

Long time reader, first time poster. Long story short I picked my Gtab up after a long hiatus and wanted to load a custom boot logo to replace the g-tablet logo. Unfortunately I coudlnt find any posts for windows-only users. I found 2 sites with really helpful guides and put 2 n 2 together. I was stoked when my custom logo worked! Credit goes out to Igorv at Slatedroid and LeslieAnn from Android Central forums for their well detailed guides. Special thanks goes out to rajeevvp for compiling the cwm script.

Running Flashback ROM on BL 1.2.

Standard Disclaimer:

Use at your own risk. Im not responsible for what happens to your tablet. Nor do I know how this will affect your other apps. Its highly recommended you do a back up.

Required:

- Gtablet

- 1024x600 pixel image of choice

- Update.zip from Igorv at Slatedroid

- boot_screen_logo_creation_package.rar from LeslieAnn at Android Central

- CWM experience

- Command Prompt experience

This was created for Viewsonic G-tablet. It will replace 2nd boot logo (logo after birds).

Using Clockworkmod flash "update.zip" as you would with a ROM. It will only replace logo.

A. Download one of the Gtablet.zip file from Igorv (See Link 1 below)

B. Unpack any one of the update.zip files. You should have subfolders META-INF and tmp folders. You will replace the initlogo.rle in the tmp folder later.

C. Choose or Create any image file you want to replace the logo with. Make sure the dimensions are 1024x600 pixels

D. Create the RLE file with LeslieAnn's guide (See Link 2 below)

Install:

Extract the boot_screen_logo_creation_package.rar file someplace (see Link 3 below), I recommend something short because you will have to type the location. I use my D drive and a folder named RLE. So D:\RLE is the location I put these files.

How to create an rle file:

Step 1

Make the image you want to use. It MUST be 1024x600 pixels (for the G Tablet).

Step 2

Save the file as a PNG file to the directory you extracted the tool (in my case D:\RLE). I also save the file as a psd so I can later edit it further in a folder specifically for storing this stuff.

Step 3

Go to your start menu and find Command Prompt. This will be in (All) Programs/Accessories.

Step 4

Go to the folder you put the tool, in my case D:\RLE

Step 5

Run the tool, you need to know the name of the png file, again, in my case this is logo.png. Run the tool with the command:

convert_image_to_rle.bat logo.png

You should be left with the raw file, a png file and an rle file, all named logo.

Step 6

Rename the rle file to initlogo.rle and place the file into the update\tmp folder

E. repackage both the META-INF and tmp folder into a new update.zip file. (do not repackage the update folder. Repackage both the META-INF and tmp folders.)

F. Copy the update.zip file into your internal SD card

G. flash the update.zip file you created in CWM like you normally would for a rom

H. Reboot twice and enjoy! (mine hung after the 2nd boot logo and wouldnt get to the boot animation. a second reboot did the trick)

Thanks
