Hello I also own an a380.
One recommendation I have for you is to not post anything about the a380 anywhere else other than in the a380 section of the forums because you will likely get overlooked by all the a320 people.
Now regarding the firmware upgrade you wish to undertake here are the basic steps:
Download:
Disk Image Writer for Windows:
http://dl.dropbox.com/u/525714/win32diskimager-binary.zipSD formatter 3.1
https://www.sdcard.org/downloads/formatter_3/ ( you could try formatting using the default windows formatter but I ran into an weird glitch that made my SD 1gb everytime )
Using the SD formatter tool I provided in the link should be safer to use.
Okay so first of all backup all the emulators and all the folders. (copy and paste them to computer)
Then you must unscrew your dingoo a380 and take out the micro sd that is shown in this video.

So once you got hold of the micro sd pop that micro sd into your computer by putting it in a sd adapter or usb adapter, or maybe even putting it in your cellphone and using your cellphone as some sort of adapter
Once your done that you need to use the SD formatter to format the micro sd. It should not be too hard. Just select the drive your micro sd is in and select format.
Then use Disk Image Writer tool to write the the firmware file to the micro sd. ( not hard either )
Then just pop ur micro sd back into your dingoo, screw your dingoo back up. Turn it on then reset by pressing the small reset button on the side with something pointy. Turn it on plug it into your computer then place the emulator folders and all the other folders back to where they originally were.
And there you go. Phew!
