Hi - I'd really appreciate some help with trying to boot my A500.

I have spent hours over the last week trying to boot my A500, and am literally going mad.

About 2 weeks ago - my A500 froze on a webpage, and the screen was unresponsive.
I tried turning the unit off and back on again, and it just hung on the acer screen.

I did A LOT of reading around - and tried the following
- Paperclip in the reset hole
- trying to USB the tab to my PC. Windows doesn'tt recognize it. I have installed the Acer USB software.
- Volume up with power on and the toggle switch
- Volume down with power on
- emailing acer tech support, twice without a response other than the auto "You will receive a response within 24 hours"

When I do the volume down and power on - I get the Android icon with the exclamation mark, then the tab boots and I get to a screen asking for a password.
I have tried my google password without success. I have never set up a password to lock the tablet.

I have then downloaded what seems like a hundred ROM's copied to 3 different micro SD's with a variety of different formatting. Saving the files as update, update.zip, and their original file name, and unzipping them on the root of the micro sd card.
When I try the volume down and power - I still get the exclamation mark - and eventually directed to the password page again. I see the icon to show there is an SD card in the device at the bottom right of the screen.

I have also tried plugging in my wireless USB keyboard - doing the volume down power thing while pressing home on the keyboard.
I get the following options:
reboot system now
apply update from external storage
wipe data/ factory reset
wipe cache partition

I have tried them all. Reboot system takes me back the password prompt.
When I apply update from external storage - I get the following message:

E:unknown volume from path [/sdcard]
E:error opening /sdcard: No such file or directory
E: unknown volume for path [/sdcard]

It seems to me that the a500 isn't picking up the update.zip or recognizing the micro SD card.

Does anyone have a link to a stock ROM that they know to work (I have downloaded many - but get the above scenario every time)
Any advice on the password?
Any advice on flashing the ROM - why isn't the A500 picking up the micro SD card - when I know it has read these cards in the past?

I bought the device from a company called valuetech ltd through Amazon UK, who gave me a 3 month guarantee, which has recently expired. I have the box etc.

I haven't rooted the A500 at any point, and haven't installed anything other than the stock updates.

This is driving me demented, and I would genuinely appreciate any help. Thanks for your time reading this.

Dave
