I previously had rooted my Nook Color and when the update came, the root was messed up. So, I reverted it back to stock with 1.2.0 version. Here are my questions. 1. If I do a dual boot on an SD card, will Nook Updates ruin the root? 2. Should I do the 1.4.3 Nook Update before I root the SD card? 3. If I root the NC and totally wipe out NC, will it still update? 4. If I do a dual boot on an 8 gig SD card, will I be able to use the available space for ebooks? Last time I did the dual boot, I could not access my ebooks on the SD card. 5. I was running CyanogenMod 7 before--are the newer versions better/stable? 6. Is there a way to block the Nook Updates? I think that's about it, but I might have more questions. Thanks.
