So i finally got this to work, the trick for me was using the 1/5 partition script before the prep-dualboot... Also making sure you hold the N button while rebooting not just when you see the screen multi-boot...

Does anyone know a prep-boot that will run with the 5/1 partitioning script?

Can anyone point me in the direction for fixing the market it errors out everthing i try and download something in the 1.2 boot
[Nook Color General] jasoraso:
My method uses 2 steps (after the Manual Nooter step 2):

step 3A = flash "dual boot prep.zip" - this is the file shrinks the /media partition, making room for the 2nd partition. if you need this file, you can download here:http://db.tt/TaYbMFv

step 3B = flash "froyo to dual boot" - this copies the B&N Froyo installation from

the first booting partition to the second booting partition, and renames the file to uAltImg, which is what CM7 looks for when booting from the second partition. Download here: http://db.tt/SvVAQrx

Those are the 2 simple steps to created the second booting partition. Then proceed with the normal cm7 installation.

The only caveat I have is that the dual boot prep file is expecting the OLD partition schema that B&N used (with a 5gb /media partition). If you have a "blue dot" Nook with the 1gb /media partition, you will need to find the thread to repartition to the old way and do that first).

IF you want the B&N Froyo to be rooted, you will want to flash the manualnooter.zip BEFORE copying to the second partition. Yes, this step is what roots the B&N froyo. You technically DON'T have to root though. You can copy the B&N to the second partition w/o it being rooted. You may prefer to do this if you want the B&N to look completely stock, and still have "read in store" access. The rooting process MAY interfere with the read in store. However, if you don't root the B&N, there may be possible issues in the future if/when B&N updates its software - I image the update might get confused because it is on the second partition.

I think the apkenable step is optional.
[Nook Color General] jasoraso:
One other tip:

Shortcut to boot into 2nd/dual boot partition:

Hold down VOL + and Vol - while powering on -

it will boot straight to the 2nd partition (bypassing the boot menu).
[Nook Color General] jasoraso:
There is a shortcut!!! You can do it all from CWM that is already on your NC.

All you need to do is flash the dual boot prep file (this will shrink your /media partition). Then flash the Froyo to dual boot file in my earlier post. This file copies your primary o/s partition to the 2nd o/s partition, and names the files the way cm7 dual boot will look for them.

The follow the steps to install cm7 on your primary partition (wipe system/data etc) to erase the original B&N, and flash the cm7 nightly and cm7 gapps.

Do IT!
[Nook Color General] jasoraso:
To fix the Market, try going into manage apps and clearing the data for the market app. Then reboot and it should work.
[Nook Color General] rukawa11:
Hey, when i posted before I followed the ops steps already and did the prepdualboot before i installed the stock 1.2, basically i'm up to step 2 and just waiting for barnes and nobles to reregister the device to my name from the previous owner, so that I can sign in and finish initial setup(i was getting sign in errors because b&N only allows one email per serial number)) then I will manualnooter and then froyo to dual boot. so basically i'm asking is it ok to dualboot prep->install 1.2->manualnooter->froyotodualboot? If not how can I redo this, thanks.

by the way i did have the blue dot and kept getting errors running dualbootprep so i researched and redid the partitions and it worked afterwards

EDIT - I proceeded and everything worked fine. AWESOME. thanks again guys
[Nook Color General] rukawa11:
I installed the dalingrin OC, i went into cm setttings/performance, and it's currently set to 300/800. is the dalingrin OC zip that I installed the same as cm settings/performance or is it anohter app?
[Nook Color General] AidenM:
If your sure you installed the OC kernel, download Nook Tweaks from the market.
[Nook Color General] rukawa11:
Crap, I just tried to boot into stock 1.2 for the first time and it didn't work. maybe I did have to do prepdual boot after installing 1.2? is there anything i can do to fix it now?
[Nook Color General] rukawa11:
i downloaded nook tweaks and it was already set up to 1200 step 5, but when i go into cm settings it still says max cpu frequency 800, do i have to change it to 1200 on that also? thanks for the quick reply iking
[Nook Color General] jasoraso:
You may need to reboot. When I change the CPU settings in Nook Tweaks, it is reflected in Settings/CyanogenMod/Performance. I used the back arrow in Nook Tweaks after making changes.

Also, the latest CM nightlies INCLUDE the o/c kernel! Yeah! No need to flash the kernel again after updating the CM nightly!

You also may want to download the app "CPU Spy" to see what cpu the NC is running at (the time spent at each cpu "step").
[Nook Color General] rukawa11:
thanks, I used cpu spy and saw that it wasnt be oc'd so I manually changed it on cm setting/performance to the same max as nook tweaks and its oc'd now. Still I'm not sure if I wiped out stock 1.2 because it doesn't boot to stock 1.2 if i press n or volume buttons. is there a way to check if i still have it?
[Nook Color General] rtod4edw:
shortuct bombed....

Very sad....:(

Started with the following steps...

0) Go into ROM Manger Backup+Restore and create a backup

1) Go into ROM Manger to Install ROM from SD to Flash the dual boot prep file (this will shrink your /media partition)

prep-dualboot-0.1.zip

Unfortunaely it Boots into previous rooted Froyo 2.2.1 NC running a custom ROM kernel 2.6.29-omap1 from eMMc. IF I continue with the orignal plan I will have dual boot but without Stock NC 1.2 in 2nd artition.

decided to try...

1a) Go into ROM Manger to Install ROM from SD to choose downloaded stock 1.2 Zip. It should be called "update_nc_stock_1.2_keepcwm.zip" Flash that. Now wait for it to install. Reboot your Nook.

Now its Stock 1.2 sort of but cannot figure out how to get it to boot CWM from just installed "update_nc_stock_1.2_keepcwm.zip" to primary partition.

Try to build CMW SD card and it just down't seem to want to boot from SD card. No longer root so my ROM Manager cannot install CWM or boot into it.

Very sad... :( & :confused:

ROM Manger application says I have CWM 3.2.0.1 install and I cannot figure out how to get into Recovery from power off... Which buttons to hold.

Powered down... screen goes fuzzy... turn off NC.

Hold power on & N button... get "ReadForever" then black and then nookcolor splash screen. Looks half way like my old ROM, launcher and apps with stock status bar at the bottom.

I have backup... if I just could get to CWM recovery to restore.
[Nook Color General] jasoraso:
Sounds like CWR didn't get flashed properly to the recovery partition, if you can't boot into it by holding the N button while powering on.

One other thing to try is to tell Rom Manager to boot you into Recovery (2nd option from the top in the menu list in Rom Manager). If it is installed properly, this should work (although if you really lost superuser than it probably won't).

If you can't get into Clockwork Recovery, you will need to figure out the SD card issue and get cwr on it ...

I would review the steps to create the SD Card ...
[Nook Color General] rknight68:
Still no luck

I still can't get the NOOK app to d/l my books from within cm7, they show up, but will not download. new items work spiratically.

If this would work, I would ditch the Stock all together and go straight CM7!
[Nook Color General] rukawa11:
still need help about this, pressing n or volume up and down buttons didnt do anything. it just boots into cm7
[Nook Color General] rtod4edw:
Running CM7 night 144 & happy without dual boot

That was big clue... "holding the N button while powering on." with the USB cable connected to the PC. Finally I was so happy to see CWM Rocovery.

Then I got brave and did picked up with the following steps.

1a) Go into ROM Manger to Install ROM from SD to choose downloaded stock 1.2 Zip. It should be called "update_nc_stock_1.2_keepcwm.zip" Flash that (wipe system/data etc). Now wait for it to install. Reboot your Nook. It will boot and will ask you to setup the Nook. Set it up. After setting up, boot back into CWM using your sd card - Hold N while power on until CWM Recovery menu

2) You want the B&N Froyo to be rooted, you want to flash the manualnooter.zip BEFORE copying to the second partition. Yes, this step is what roots the B&N froyo.

manualnooter-4-6-16.zip

2a) That will take one minute to flash. Reboot again. Make sure your root is setup. To confirm, download an app from the market. Any app. Like ROM Manger which required root. Proves you are SuperUser.

3) Then from ROM Manager flash the Froyo to dual boot file in my earlier post. This file copies your primary o/s partition to the 2nd o/s partition, and names the files the way cm7 dual boot will look for them.

froyo-to-dual-boot-flashable-uAlt.v0.2.zip

4) Then follow the steps to install cm7 on your primary partition (wipe system/data etc) to erase the original B&N, and flash the cm7 nightly and cm7 gapps.

Now from ROM Manger wipe system+data+cache. Now choose zip again, but this time pick CM7 (I usedcm_encore_full-140.zip) then GAPPS. Then anything else, OC kernel.

6) Now flash Multi-Uboot-0.3.zip. (multi)U-Boot V0.3 loading.... and nothing ever happens... very sad... :eek: :( after many tries of "holding the N button while powering on." with the USB cable connected to the PC.

7) Decided stock NC 1.2 isn't worth the effort. Rebooted into recovery and then flashed remove-dualboot-0-1.zip

8) Then finally got t back into CWM Recovery and flashed CM7 cm_encore_full-140.zip

Now reboot without holding anything. It booted CM7.

Thank for the support & suggestions. I will try again later but it's 2:30 AM now & I need to sleep before I have to go to work in the AM.

Stock 1.2 Stuck on "Nook Color" Splash Screen

So, I finally got the froyo dual boot to work last night. Afterwards, I was setting up both CM7 and Stock 1.2 with all the apps I like. Eventually, when doing the 3rd or 4th alternate boot into Stock 1.2, my NC hung on the "Nook Color" splash screen. I think this may have been caused by me doing a hard shutdown after the NC got hung up on something. At any rate, here's my question. Is there any way to fix this problem without completely starting over? Since I have CM7 all setup the way I like it, it would be a shame if I have to start over.
[Nook Color General] godgib:
I have everthing setup and working.. Does anyone know if I run the 5/1 partitioning script, will it break my installs, Or does anyone know of a prepboot that will run on the 5/1 partitioning

Nope, not seen a script for 5/1.

[Nook Color General] myersw:
Well I finally was successful getting dual boot to work. With this procedure I can do the CM7 nightlys without having to reinstall multiboot. What made the difference for me was using the froyo to dual boot in place of the eclair to dual boot and then not doing the multi boot at the end of this procedure. I did a modification of this which yelloguy submitted

yelloguy procedure:

Install removal script for dual boot found in these forums

Install stock 1.2 from the link mentioned in OP

Boot 1.2 and register the device

Sleep 7.5 hours and then chat with iKingBlack :-)

Install manual nooter, then the apk enabler

Boot 1.2 to check root access

(no boot from now on)

Install prep dual boot

Install eclair to dual boot

Format system, data and cache

Install CM7 nightly

Install gapps

Install multi boot

Reboot holding N and check stock works as it used to

Reboot normally, check CM7 works and set it up

Since then I have used both partitions successfully.

What I did that worked for me.

Nook app..fixed itself?

SO my nook app started working after no changes were made. All books downloaded. It was working really well under dual boot. So well in fact that I didn't see any reason to use stock 1.2 any longer so I switched to full on CM7 only as described in the CM7 on EMMC on any nook thread.

Working great and has a great deal more speed than dual boot did for me!
[Nook Color General] woodsjs:
Used the modified version of the install on my blue dot, repartitioned to old nook spec

flash 1.2

flash ManualNooter

reboot

flash prep dualboot

flash froyo to dual boot

wipe

flash CM7

flash GAPPS

Now have a spiffy dual bootin nook. I decided not to flash the multiboot and am using the CM bootloader.

Thanks to all who made this possible!

CM7 nightly updates

Hi everyone,

I am running CM7 nightly 153. Since 155 is already out, I'd like to update, but I was wondering how to do that since my NC is running the configuration described in this thread. And if I do update to a new nightly, will all my stuff (apps, etc) be there still, or do I have to do a CW backup, install the new nightly, and restore the backup to the new nightly?

Since CM7 is on the main partition, if I "install from zip" a new nightly build, will it automatically update the CM7 partition, or will I screw something up. Sorry and thanks in advance - I'm still pretty new to this...
[Nook Color General] AidenM:
You can update the nightly, but you will have to reflash multi-uboot.
[Nook Color General] whereiszack:
Worked like a charm. Thanks!
[Nook Color General] whereiszack:
restoring CWM backup

Hi guys,

I'm now doing this to a friend's NC, and I made a backup as instructed, but the author doesn't say when to use the restore. Can I do it after the entire process is done, or do I need to do it before I move the stock NC OS to the second partition?

Thanks.
[Nook Color General] ccapasso:
If the backup is just like all other nandroids, it is only to be used in the event something goes wrong. Think of it like System Restore for Windows. You would put the backup back on your sd card and restore it in case things go south :).
[Nook Color General] Ogund:
Edit: BLAST I somehow missed a couple pages on the repartition comments, so I feel like a collossal idiot and this post is redundant and uninformative. Leaving it be for the moment in case anyone else is as stupid as me, but I take no credit for information given.

I very much hope I'm not out of place, but I've read the thread and encountered a ton of the issues people have noted, so I'd like to post my fix:

If you go into your standard nook config and get '5 gigabytes of space' you are not who I'm aiming at. I was excited and happy to attempt to set up dual boot but I could not delete /data (as numerious other people in this thread seem to have issues doing). It turns out that if you have a preformated with 1.2 nook (also known as a 'blue dot' nook, because of the dot on the packaging, though mine apparently was never applied or fell off) you have a different partitioning scheme. To fix this, I recommend http://xdaforums.com/showthread.php?t=1094371 . For dual booting (as this is the dual booting thread!) you should choose the 1 gigabyte data, 5 gigabyte media format, because this is what the dual partition prep script expects.

Once I ran that, and the reformat, I was able to install without issue (note!: you MUST reformat data, cache, and system as recomended in the OP- very important!), exactly as the steps required. There is no 'need' to root the 1.2 build (also noted in the OP), but YMMV.

The reason the OP (and many others!) are unable to recreate the issues is because the newer (infamous blue dot) nooks are paritioned in a different way. The repartitioning to the old mechanism seems to turn them into older-style nooks without problem though, and you can set it back to the new system without issue using the CWM install.

Once I got the basic issues sorted out, this guide helped me install without concern, though the OC zip is no longer required on nightly builds (it was apparently folded in), and can just be accessed in the CM7 config files.

Tl;dr version is- If you are getting errors in the primary install, and cannot format /data from a CWM boot on a uSD card, I advise attempting the reparition files linked at the top of this post, specifically the 1gig repartion file. Post that, follow all instructions in the OP and everything 'should' work smoothly.

First post, hope it's up the standards.
[Nook Color General] ccapasso:
Followed the directions and everything worked perfectly, thanks for the guide.

The only thing I've noticed is some market apps show up (in CM7 Stable), but without an install button option (es file explorer, friendcaster, facebook ,etc). Anyone else have this problem and/or know a fix?
[Nook Color General] les02jen17:
Just read the whole thread and at one point I think I finally know how to make it work, and then another I have doubts again. :(

Tell me:

I want to be able to dual boot a ROOTED Stock 1.2 that has been partitioned with a custom partition (2GB DATA/4GB Media) with a CM7 Nightly (that can be updated regularly without too much of a hassle).

Is this the guide to follow? Please bear with me guys.
[Nook Color General] jasoraso:
There are few other threads on this - you might search for them. But the my solution is to:

- use Root Explorer to change the lcd density from 161 to 160 in build.prop in /system (you may need to buy this for $2 or whatever)

- reboot

- goto settings:applications:all apps:market and clear data

The market will ask you to "accept" again ... then you should be able to find all the apps, and install them. HOWEVER, this solution is only temporary for me. I need repeat step 3 quite often.
[Nook Color General] jasoraso:
Yep, this guide works great. One thing to note, the OP guide provides a different multiboot than cm7. So when you flash a new nightly, you need to follow up with a second flash of the op's multiboot. pretty easy to do, just keep the multiboot.zip on your sdcard.

If you follow the alternate steps I outlined in a previous post in this thread, you won't need to flash the multiboot.zip each time you update a nightly, because it will be using the cm7 multiboot instead.
[Nook Color General] goldiefish:
I'm very familiar with reflashing stock 1.2 and starting over. :o SO, I'm not afraid!

Question: If I (a) remove dual boot; (b) flash stock 1.2; (c) update to stock 1.3; (d) prep dual boot and push stock UNROOTED 1.3 to the alternate partition; (e) format /system, /data and /cache; (f) flash latest CM7 nightly, gapps, dal's OC and multiboot...

Will it work? Can I even push unrooted 1.3 to the alt partition? And, when I flash CM, will I have root? Market?

Thanks, as always to the awesome folks here.
[Nook Color General] jasoraso:
Edit:

I posted a zip below that will flash BN1.3 straight to the 2nd partition. This is NOT rooted; and will mess up root if you have it rooted ...

but it is easier than jumping through all the steps listed below.

-----

Yep, that will work perfectly. I am about to do the same thing on 3 Nooks right now. (Well, at least it worked that way for me w/ 1.2 - I expect that 1.3 will be fine too). You don't need to have 1.2/1.3 rooted to move it to the 2nd/alt partition.

Oh, I'm going to be using CWR to make a nandroid backup of my cm7 installation first, though. I guess there is a slight possibility that restoring the nandroid after recreating the dualboot will wipe the kernel of the 1.3 .... I need to think about that ...
[Nook Color General] goldiefish:
Thanks. Worked perfectly. I now have dual boot again and I restored my nandriod backup (MIUIus 1.8.5) and it didn't adversely affect 1.3. Of course, I had to reflash the multiboot 0.4, but you know that!

Next, I'll try it again but I'll manual nooter 1.3 before pushing it to the alt partition. If it doesn't work, I'm still happy with being able to choose between stock, unrooted 1.3 and the custom ROM(s).
[Nook Color General] Taosaur:
jaso, the dropbox link from your first post is dead. Any chance you could re-host it?
[Nook Color General] jasoraso:
Here's a link to a flashable .zip that will move the froyo B&N 1.2/1.3 from the 1st partition to the 2nd partition.

http://dl.dropbox.com/u/6776060/froyo-to-dual-boot-flashable-uAlt.v0.2.zip

Here is a B&N 1.3 .zip that is modified to install to the 2nd partition. My 1.2 that was rooted; it isn't now. I used this to flash several Nooks that had B&N 1.2 on the second partition (they weren't rooted).

http://dl.dropbox.com/u/6776060/BN_1.3_dual.zip
[Nook Color General] Taosaur:
I've been looking all over for a CWM flashable 1.3 zip! I assume this one is made to work with CWM, and I've been assuming all along that B&N's .zip will not--is that correct?

So, to use these files with CWM on eMMC, I'll want to start with 1.2 from the OP, move it to the second partition, then install your modified 1.3, correct?

ETA: to save myself some steps, would changing uboot.altimg and uboot.altram to uboot.img and uboot.ram be the only necessary changes to flash that 1.3 .zip with CWM before creating the partitions?
[Nook Color General] jasoraso:
That is basically what I did in creating the 1.3 zip. I took out the files that would flash the recovery, and changed the system partition that is mounted from p5 to p9. I also renamed the new kernal to uAltImg instead of uimage, and included a routine from the original froyotodual boot that repacks the ramdisk to point to the same cache partition (I think that is what it does).

I think what you are suggesting would work as well, though.
[Nook Color General] Taosaur:
I tried a couple different ways and both got me access to CM7, but neither would boot to the second partition. I'm shelving it for now--probably give it another go Sunday, or I might get a chance tomorrow.

missing android market

Hi I followed the dual boot process and it worked, well except that the android Market app is missing in CM7 which with out it I cant download other apps.

Nook automatic 1.3 update and dual booting

So, I just found this thread tonight because I decided to restore my rooted Nook (CM7 stable on emmc) to Nook stock and then set it up to dual boot with both Nook 1.3 stock and CM7/Phiremod/MIUI on emmc.

If I do this and Barnes & Noble then relases another update, will:

The update install automatically (since the stock ROM would be on the second partition)?

The update cause any problems (such as disrupt the dual boot functionality)?

Thanks ahead of time for your help! The helpfulness of the members of this forum is amazing.
