I have successfully rooted 2 Nook tablets, both from 1.4.0, the first using Indirect's script with Zergrush and the second with Albert's SD card method. Both methods worked at 1st attempt and took no more than 10-15 minutes each. Kudos to all the people who contributed their skills.
Both tablets have OTA blocked with version # 9.9.9. B&N now is offering to repartion the 16 GB tablets after 3/12/12 but only in store. Is there a way to repartition without going back to stock unrooted status? The tablets are working great, but I would like the option of increasing space available without having to repeat and possibly mess up the root process!
