    Thanks so much for the instructions. I loaded up the SD card and can see all the files you said to load onto it. But when I try to boot my NC, I get the 'Loading' and the skulls and then it turns off. Am I missing something? :)

    Sounds like somethings screwed up. I've never heard of that problem.

    Try flashing w/o copying the 3.2.0.1 files. If that works, then unzip the files again (3rd post).

    great write up. not new to rooting at all,but very new to NC :eek: i just picked one up thats running cm7 from the sd card. looks like the device itself is not rooted.

    just to make sure i understand this correctly,if i make a bootable CWM SD,roms i flash from it will be flashed and run from internal memory,correct? can i immeidately make a backup of stock,unrooted firmware if i need that for later?

    once ive flashed a rooted rom,or rooted the stock 1.3 firmware the manualnooter way,i could then flash CWM to the internal memory correct and keep the sd card CW for emergencies?

    thanks again for the awsome guide,ill definately be doing this later,as cm7 from the sd seems a lil laggy and not everything works correctly. hopefully installing it on the internal memory(like im used to with my phones) is better. :)

    I can't speak for roms installed on the sdcard (they're quirky), but if you root your stock rom, or have any rom installed on your Nook, you can back it up with Rom Manager/CWM Recovery.

    A roms flashed from this bootable CWM sdcard will be on your Nook (aka EMMC). If you wanted a backup, you'd want to do that first :D O/W it's easy to return to stock.

    IMO Sdcard installs are fragile (sdcards fail), more difficult to create/update, and slower than roms on the Nook. Most of the guides here are for emmc installs so ask before trying to update your sdcard install if you don't see specific mention of that.

    ***Edit** I used win32diskimager and it worked!!


    Alright admitted noob to this.. I've read and reread the directions and have a .img file of the 2gb_clockwork-3.0.2.8 file. I have the winimage and winrar loaded. I reformatted my 2gb sandisk mircosd card to fat32. I can copy stuff to and from the msd card. When I try to use Winimage to restore virtual image to physical drive it doesn't see my sd card or anything else as an option. I did check the box to use removable drives. I've tried extracting the uImage and uramdisk files to the msd card and boot it off the nook but the msd card does seem to be bootable. I'm pretty sure it's the restore image process that I'm missing..

    BTW thanks for all the effort and time you've taken documenting everything.

    Oh another stupid question.. Do you have to root the NC before you repartition and load the CM7? I figured if i didn't want anything to do with the old BN image then I could just nuke and pave.. I want to use the internal memory and then add a msd card to addition space afterwards. Thanks again

    Yeah I did use win32imager and it worked.. Now I'm backing up my BN image and then attempting to repartition. A couple of the links in the XDA article are dead but they have a couple of "automated" scripts in zip files that you can use to repartition and then format? Have you had any luck going that way?

    Thanks

    I've followed your instructions to the letter for a 1GB, 4GB, & 8GB uSD cards but none will boot in recovery. I have 2 NCs running stock 1.4.0.
    I've tried using WinImage & Win32DiskImager. I get no errors on the PC. When I put the uSD cards in, it always boots in stock ROM.
    Does this happen because I have 1.4.0 & have to root it?
    I saw that you said if it boots in ROM then the install was probably faulty.
    I haven't gotten to the step of installing gapps & cm_encore_full-253.
    Thoughts?

    Did you say 1.4.0? That's the rom version for the Nook Tablet. This is the Nook Color forum. The NC is version 1.4.1.

    These roms do not work on the Nook Tablet. :D

    Assuming you had a typo, it sounds like a problem with your card reader.

    Not a typo, noob move; Nook Tablet in hand. Thanks for saving me from myself!

    I updated the 3rd post above to make your bootable sdcard use the touchscreen (TWRP). :D

    Now just need to figure out an easy way of installing on EMMC w/o adb.

    If I have a new NC with 1.4.1 will this guide work without any problems?
  19. colchiro

    colchiro Well-Known Member

    Sure. The bootable card still works. What you do with it may change tho. :D

    What's your intent, installing a custom rom like CM7 or rooting?

    I'm thinking in dual booting CM7 and stock, but since my NC updated by itself to 1.4.1 its been quite difficult since most guides dont mention if it affects the process. Do you know any tip or guide?

    I had 1.4.1 pushed to me, wipe to factory settings which took me to 1.0.1 and from there I used a cwm sd card to re-root and go with cyanogen.... not sure why i waited this long. This is unbelievable, definitely suggest going with cyanogen 7.1.

    It just depends on what your main function is. If you're reading book 90% of the time and need the specialty features, then rooted stock might be ok.

    OTOH, if you don't read or reading is a small % of your time or a simple reader is adequate, then installing CM7.1 is the way to go.

    IMO Aldiko>nook app any day of week. as long as any books you already have are epubs you are good to go. (aldiko is app in market)
