Manual Update from SD Card


Oct 19, 2012
Tring to manually update Acer a100 to ICS. Tablet is currently bricked.
I tried reseting it. Power + Volume down.

Trying to install it from an SD card now. I downloaded it from ACER changed the name to transfered it to my sd card.
Held the power and volume button.
Looked like it was going to work. Said something about on the screen. Then went to a Anroid with a exclamation mark.

Do i need to put the in a folder on the sd card. Format it a certain way.

I'm lost, Help
