I'm sorry guys, I didn't know that there were any Ampe A10 Freescale Quad users here. It sounds like you are all experiencing the same problem though, and maybe I can be of help.
First, I own an Ampe A10 and just dearly love it. More about the reasons why later.
The Ampe/Haipad/Sanei Freescale Quad are all produced by the same manufacturer for different markets and are exactly the same tablet. The problem though is that this particular tablet has been produced with two different screens with somewhat different properties. This is not real obvious and the manufacturer has not made it easy to figure out.
Unfortunately, the manufacturer is not real good at communication in English and has some strange ways of doing business using a Chinese model.
Any way, it seems like all of you have the new screen and tried to install the firmware for the old screen. This has strange, but predictable effects. A washed out, pixelated, or random snow like effect is not uncommon. If you look here, you should find the proper firmware for your tablets.
The third item down should solve your problem.
This is the R1-5_1.64_W2-signed.zip
If you look in the Settings menu on your tablet under About, the build number should have a "W" in it. Anyway, there are a few tips I want to give you about properly installing your firmware.
1. If you haven't done so already, buy a micro sdhc card for the USB slot on your tablet.
2. Install Titanium Backup on your tablet. Do a complete backup to this external card.
3. Download the software above to the tablet.
4. If you haven't done so already, download a good file manager that allows you to unzip filesto your tablet.
5. Move the firmware zip file to the external sd card.
6. I strongly suggest though it isn't absolutely necessary that next you look in "Settings" again, go to Backup/Reset, check both boxes and do a Factory data reset. This will erase everything on the main card and restore to Chinese language. After the tablet reboots, if you don't speak Chinese, go to settings again, look at the 6th item from the bottom, click on it and look for English.
7. Now, re-download the file manager, and use it to open the external card, and unzip the firmware file to the main directory of the internal sd card. Having done this, shut the tablet off.
8. Finally, while holding down the right volume button(-), press the power button till the penguins appear. Let go of this button. When the upgrade screen appears, let go off the power button.
Your tablet should look right now, and you can re-download Titanium Backup, then restore your files from your external sd card.
I'll check back in a day or two and see how you are all doing.
