Booting Android Jelly Bean 4.1 from SDCard for Nook Tablet


This is a supplementary file. This is not a rom. Not tested. Not for 8GB Nook Tablet.

Download the rom by chrmhoffmann here: http://forum.xda-developers.com
Follow “How to Guide: Dual-boot (CM7/CM9) SDCard for Nook Tablet (Updated 5-28)“.

What’s in the cm10-acclaim-0.02_sd_hd.zip file?

  • boot.img – a modified boot.img for booting Jelly Bean off of SDCard ext4 partition 2
  • flashing_boot.img – new Cyanoboot (a modified bootloader for multi-boot) with volume keys support for moving up and down menu. You press home key to select. This build boot files boot.img, altboot.img, altboot1.img, altboot2.img, altboot3.img, and recovery.img off of SDCard and altboot.img placed on the bootdata partition. Unlike the previous one where it was made easier to distinguish between cm7 and cm9 by booting files cm7.img and cm9.img, it’s no longer the case.
  • updater-script – a modified edify script for installing Jelly Bean on system partition on SDCard.

If you previously installed CM7 or CM9 on your SDCard, you need to clear your data1 or data2 partition.

    Here is exactly the steps I take / took
    Format sdcard sdc1=fat32 (active), sdc2=ext4 sdc3=fat32
    copy boot.img and flashing_boot.img from cm10-acclaim-0.02_sd_hd.zip to sdc1
    copy updater-script from cm10-acclaim-0.02_sd_hd.zip into cm10-acclaim-0.06.1-full-of-bugs.zip using winrar, to path META-INF\com\google\android
    copy MLO,u-boot.bin and recovery.img to sdc1 from cm10-acclaim-0.06.1_sd_hd_10_27
    copy gapps-jb-20120726-signed.zip with updater-script from p2-gapps-ics-20120429-signed.zip
    Boot and see the cyanoboot menu
    Hold the N button to get the menu
    choose sdc recovery
    choose install zip from sdcard
    Choose zip from sdcard
    Apply cm10-acclaim-0.06.1-full-of-bugs.zip
    Apply gapps-jb-20120726-signed.zip
    Hit power button until I can choose power off from cyanoboot menu
    Power on, do not touch anything
    Get error booti: bad boot image magic (in memory)

    I am usually pretty good at following directions, but I am definitely messing a step up somehow.

    I gave the instructions a try, but ended up with a bad boot image magic error.

    I applied the jelly bean 0.6.1 with gapps for jelly bean (modified the updater script in gapps to match the mount mods made to the 4.0 ics gapps.)

    Any idea why it hates me?

  3. Rob says:

    Does anyone have a link to a sd version image for Jelly Bean 0.6.1 similar to what was posted here:

    iamafanof,
    I have been running CM7 for sometime now and love it but really would like to get the more polished CM10 but I am having a hard time following the blog and not really finding a step-by-step here. As I understand it, I am putting the cm10-acclaim-0.05.1_sd_hd_9_4 file contents into the boot partition but what about the but I also need the p2 and p5 folders? What are they for? Am I picking one or the other?
    Lastly, where does chrmhoffmann’s file go?
    Any enlightenment would be appreciated and thanks for the info!

    Hi, I managed to figure out the recovery.img solution by finding that file from the cm9 sdcard post earlier. However, now, I am trying to flash jelly bean gapps 20120711, but I think I need to modify the updater-script within that file to allow it to flash onto the system partition of the sdcard, rather than the emmc. Is it possible to modify this file in windows?

  6. The Dude says:

    With this method, I need to download both the cm10fullofbugs and the recovery.img files on XDA, correct? I attempted to start SD Recovery, but it merely went to a blank screen with the backlight on. Thanks for all your help in putting this sdcard method, huge fan!!

    Hi,
    Can you update this post with the latest 0.04.1 which is out on XDA.

    I am a big fan of the sd card boot and have been following your blog for a while now.

    Thanks
