Change Screen and resolution on Android

[gvi70000]

Does any one can point the steps to change screen and resolution on Android? I want to set the default 7" lcd from olimex.

Thank you

You need to flash NAND with the right image for the resolution/ screen size
for 7" get this https://docs.google.com/file/d/0B-bAEPML8fwlUjRLUmRydENZMXc/edit?pli=1
the wiki tells how: https://www.olimex.com/wiki/A20-OLinuXino-MICRO#How_to_download_new_Android_image_to_the_NAND_memory_of_my_A20_board.3F

I allready try this and is working. But if I i change thé screen I want to change a file, not to burn a new image.

Try to install the image on a microsd-card.
If you want to use the original-image, just leave the card and it starts from NAND.
If you put the sd-card into, it starts from there.
