Changing the bootscreen picture tutorial by lelvisl

We appologise in advance for the bad translation

You need:
SBFCodec
XVI32
SBF file for E2
RSD
240x320 GIF

Let's start:

1. Unpack the firmware with SBFCodec
Click on Open

You will see all SMG files extracted.

Get CG39 and delete the others

Copy the GIF files in that folder

Rename the gif file like shown below:.

Open the file with Win Hex
Check if the start is with 47

Go to Edit->Insert string. Choose Hexstring, mode FF, and type $800

Save it. Open the original file in the 39 folder with XVI32
Insert the string at the end of the file
You can see that at the end there are many FF values and then you will see digits. In text mode you will be able to see words. Select and use Edit->Clipboard->Copy as Hex String as shown on the screenshot

Go back to the modified file and at the end go to Edit->Insert String. Paste the copied string. The value $800 change to $1 and press OK 

The rest to the end of the file can be deleted like shown in the image below

Go to Tools and choose Overwrite. Choose G (code 47 in hex)

Place FF 8000 times before. To do this go to Edit->Insert String. Value should be FF, $8000. Save file.

The problem that comes is that the file should be exactly 131*072 bytes. For that before G(47) insert FF's as many times as needed to make the size exactly 131*072 bytes. Remove the original file and save the new one. Back in SBFCodec remove everything except RDL3 and CG39

Choose CG39 and Replace. Compille and flash with RSD Lite
