[Acer Iconia A500] JdgM3NT4L:
Ok guys, here ya go.

First. All credit goes to Skrylax_CZ and blackthund3r. All I did was record the process and post. skrylax_CZ's thread is here.

My setup for this is a Win7 64bit pc and an A500, stock rooted with V8 bootloader. You will be prompted to plug in the tablet at the appropriate time. So for now have it unplugged from the USB.

What you need.

A charged Tablet.

Installed V8 Bootloader by Scrylax_CZ (You can use V4 through V7, but your image will need to be 268x72. in other words... tiny. All images below depict an install with the V8 bootloader.)

A complete backup. (This is, after all, at your own risk.)

Your SBK number or your CPUID so you can get your SBK.

Current A500 drivers from Acers site.

An Image that is 1280x800. (If V4-V7 bootloader, use 268x72.).

Skrylax Green Background zip

(Or if V7 or less go here and grab the appropriate zip, not apx.).

Skrylax_CZ's BootLogo tool

And blackthund3r's APX flash tool

Here we go. Create a folder and unzip the three packages that you've downloaded. You should have a folder that resembles this.

Now select and open the folder named 'A500BootLogo_105_v8plus_win'. Open the program A500BootLogo.exe. You will see this.

Choose 'File' then 'Open'.

Browse to the folder where you unzipped your files and open the 500_a501_bootloaders_apx_ics_v8_green folder. Choose the file bootloader.bin.

You should see this.

Choose 'Image' then browse to the folder where your new bootlogo image is. THE IMAGE MUST BE 1280x800!!!

Here is mine.

That's Daisy!

Now I see this...

Next choose 'File' and then 'Save'. Name the file whatever you want, just leave the .bin extension alone.

Close the Bootlogo tool. Now choose and open the folder blackthund3r_A500_APX_Flash_Tool_v0.4. Open the application A500APXFlash.exe.you should see the image below. Click the blue arrow.

Enter your SBK number. Then click the blue arrow.

Select to 'Choose the files you want yourself' button. Click the blue arrow.

Tick "bootloader" then hit the arrow.

Choose the file that you named and saved earlier. Hit the arrow.

Time to plug your tab into the usb on your pc.

Skip this, just hit the arrow...

If you are rooted, choose to dump your BCT. You won't have but only one button until after you've completed this. The pic shows three buttons because I already have the files. Once it is finished hit the arrow.

Choose the 'Automatic' tab then "Enter APX Mode" button.

If your drivers aren't in order you will see this. Oops! (If this happens to you. Just make sure your tab is unplugged from the pc and download and install the drivers from the links in the window.)

If your drivers were (or are now) up to date you should get this after clicking the arrow.

The program will start it's job. You will see this on your tablet. It is my old BootLogo and at the top left it says "Entering Acer Download Mode".

Next you will be asked if your tablet is in APX mode or something like that. If your screen has the message at the top left as mine did the choose yes.

The program will once again begin working. Once it has finished you will see this.

And the program on your pc will be asking you to power down and then restart your tablet. When you restart you should see your new bootlogo! Here's mine for now...

Hope that clears that up just a bit.
