[How To] Custom Boot Pic

[living_sword]

This guide will help you to change the T-Mobile logo that comes up during boot.

Requirements:

1. Dev bootloader. If you don't have it already, read here.

2. Get ADB setup and working. Read here.

3. A 320x480, PNG image. There are several here and here.

4. Image conversion and flash tools for Windows.



Steps:

For Windows:-

1. Put fastboot.exe inside the ADB folder. If you have downloaded the SDK, that would be in the tools folder.

2. Run "CreateG1Splash.exe" which is located at CreateG1Splash\bin\Debug. Press Open and select the PNG image. Press Convert to get a mysplash.rgb565 file on the Desktop.






3. Turn-off the phone, start in bootloader mode by pressing Power + Camera button together.

4. Connect the phone to PC and hit Back or Camera button. Screen should now show FASTBOOT.

5. If you get a 'new device found' prompt, point it to the android_usb_windows folder, the same one you used during ADB setup.

a. If you don't get a driver prompt, goto Device Manager(Click Start, click Run, and then type "devmgmt.msc"), check if there is an entry ADB Interface in the list and has HTC Dream Composite... inside that entry. If you don't see that entry, Windows has automagically detected the phone as USB Mass Storage Device.

b. Scroll down to Universal Serial Bus controllers, check if you have at least one "USB Mass Storage device". If you have multiple ones, you'll need to go through each to find the correct one.

c. To find the correct one, right click on the USB Mass Storage device and click Properties. Go to the Details tab. In the combo box at the top that says "Device Instance Id", bring up the pull down and choose "Compatible Ids". If that is the correct device, then you will see 3 entries:
* USB\Class_ff&SubClass_42&Prot_03
* USB\Class_ff&SubClass_42
* USB\Class_ff
d. Once you find the correct device, go to the driver tab, and click "Update Driver". Choose "No, not this time", then "Install from a list or specific location", then "Don't search, I will choose the driver to install", and then choose the same usb driver that you used to get ADB to work.

6. To flash the new boot image, cd to Desktop from the command prompt and enter the following command:
fastboot flash splash1 mysplash.rgb565
you should see the following,



then enter: fastboot reboot. Thats it.



Linux/OS X version will be added soon.

I think I'm getting the same error as Tampabuc2004, but I don't have Vista.. I'm running regular xp.

I've got it to work - it shows the custom image very briefly but then shows the original Tmobile G1 image (which is the one I wanted rid of). Can the Tmobile one be changed/removed?

you don't have to double-click and open it. Put fastboot.exe in the ADB folder. All commands are entered through command prompt.

can you do "fastboot flash splash2 mysplash.rgb565" to send a second splash screen to replace the second splash screen (one with the android glowing in and out)?
