I have my current Nook color at 1.3.0 and rooted with no issues. Thanks to the users of this board. I have purchased a used nook color for my kids (So to leave mine alone) and it is at 1.4.1. I need to downgrade it to 1.3.0 so it matches mine. I download the BN 1.3.0 file but get an error when I try to install it. I have downgraded from 1.4.3 to 1.4.1 with no issue and got the market to work fine except the nook will not allow me to install any apps except from the market. I want to download the amazon app so I can install app that I already own and when I try I get the security error. Is there a way to get the amazon and other apps installed using version 1.4.1? or just downgrade to 1.3.0 which I know works great and already have the auto nooter zip files. thanks for any help.
