If you install Clockwork Recovery, I don't think any updates will work properly. First, the update will definitly NOT install automatically to the second partition. The update is expecting the B&N software to be on the first partition.

I didn't give this update a long enough time to see if it would cause problems, but I don't think it would have (I manually updated mine to 1.3 using a modified .zip to push it to the second partition).

Remove dual boot and start over?

Hi all,

I followed these instructions, but now I would like to remove stock completely (I made a backup of stock 1.2 and backed up on my PC).

How would I go about starting over and just doing a "normal" CM7 install to the built-in memory without any lingering ghosties from this method? I can't seem to figure out how to remove dual boot....

Also, when the SD card is inserted it ALWAYS boots into CWM. Always.

I'm sure I screwed this up myself, but even with a lot of searching I cannot find this information.

thanks!

Remove dual boot

This thread:

http://xdaforums.com/showthread.php?t=959461&highlight=dual

is the original developer of the dual boot method. In his post, you will find a link to the "remove dual boot" zip file. Flash using CWR, then flash CM7/gapps and you should be good to go. (or you may be able to restore a nandroid backup of your current cm7 installation).

For convenience, here is the remove dual boot link:

[Nook Color General] Taosaur:
I just got around to taking another stab at this, and success! After running dualboot-prep, installing 1.2, and rebooting to register, I was able to shuffle 1.2 to the alternate partition and update it to 1.3 using jaso's files a couple posts up, install a CM7 nightly to the main partition, and use Advanced restore in CWM to restore /data.

I now have my old CM7 setup back on the main partition, with B&N 1.3 available by hitting both volume keys at once during boot-up, via CM7's built-in multiboot.

A couple things I tried that didn't work:

restoring my old CM7 a piece at a time rather than starting with a fresh install.

moving B&N stock to the alt partition without booting into it to run set-up first.

Does anyone know, if I do a nandroid backup now, will it back up the whole setup, or just CM7?

ETA: I did have to go back and reflash gapps, which for some reason reset my LCD Density to 161, requiring me to re-edit build.prop to fix the market :P
[Nook Color General] jasoraso:
I believe the nandroid backup process is only programmed to backup the normal partitions, and does nothing for the second set of partitions.

Flash CM7 but want to go back and dual boot

So I finally figured out how to install CM7 then I came across this thread about dual booting into stock and another ROM. If I revert my NC back to stock(no root) how do I go about getting it set up to dual boot Phiremod and Stock 1.3? I've read through most of the entries here but couldn't find a good answer. Perhaps I am just blind.:)
[Nook Color General] Taosaur:
If Phiremod has the built-in multiboot (someone else will have to answer that), you can use the same process I did. ETA: Phiremod test 7 is reported working, but not version 6. ROMs here: https://sites.google.com/site/phiremod/nook-color-roms

Prerequisites:

CWM on either SD or internal recovery

Wi-Fi access

Materials:

prep-dualboot

froyo-to-dualboot

1.3-keep-CWM update .zip (IF you don't have an updated stock install to start out)

CM7 nightly build (must be CM 7.1, i.e. anything more recent than nightly #86)

gapps

Put all materials in your SD card's root directory.

Boot into CWM.

Backup.

If you have an existing stock install to move, skip to step 11.

From CWM main menu, in "mounts and storage," format system, data and cache.

From CWM main menu, "install zip from sdcard," and "choose zip from sdcard."

Choose the 1.3-keep-CWM file.

From CWM main menu, "reboot system now."

Complete B&N registration process

Power off and boot back into CWM. If running CWM internally, you will need to use the rhythm method:

From CWM main menu, "install zip from sdcard," and "choose zip from sdcard."

Choose the prep-dualboot file.

Choose froyo-to-dualboot.

From CWM main menu, in "mounts and storage," format system, data and cache.

Repeat step 11 and choose CM7 or Phiremod update zip.

Reboot into main partition and set up Wi-Fi.

Reboot into alt partition (hit both volume buttons at once on "CyanogenMod" loading screen) to make sure it's working.

optional: install gapps, keysmod, etc from CWM.

If you want to root stock, use Manual Nooter after step 9.

If you backed up an existing CM7 or Phiremod install in step 3, then after step 15 just install gapps, install keysmod if you want it, then from CWM's main menu, Backup & restore > Advanced Restore, and restore

data only

from your most recent backup. When you boot into CM7 (not tested with Phiremod), it will be just like you left it.

ETA:

UPDATE 9/19/11: Cut some steps thanks to rajendra82's CWM-flashable 1.3 image (thank him here), and branched the guide for those starting with stock installs.

My guide is getting very corrected, too :p
[Nook Color General] jasoraso:
Great summary above of the steps for dual-boot.

One last comment - if you have a blue dot NC, you will need to have your partition layout w/ 1gb for /data and 5gb for /media when you run the dual-boot prep in step 6 above.

see this thread if you have a blue dot and need to resize the partitions before running the dual boot prep:

[Nook Color General] futr_vision:
Thanks for the walkthrough. Sorry for all the noob questions.

Do your directions already assume I restored my NC back to stock? If I still haven't reverted back to stock from CM 7 do I still follow these instructions?

If Phiremod does not have built-in multiboot then what? It probably should since it is just a flavor of CM7 right?

Do you recommend CWM on an SD or internally? Currently I have it on a 8GB SD.

When I first put CM7 on my NC I did the recommended backup. Should I use that backup to revert to stock? Is that even possible if I already backed up CM7 as well on the same SD card?

Do I need to use Titanium Backup at all?

To install gapps I need to include that zip on the SD card as well and repeat step 5 correct? Do i install gapps at the end or should I install it earlier?

If I follow these instructions all the way through and get Phiremod running how/can I restore data from my previous CM7 install?

I think that is all for now :) I wish I understood all of this better. In time I guess.

Oh. I do have one other question. I have an unrooted Droid X. Any recommendations on what to do with this phone so it will play nicely with my NC? i.e. wifi tether

Thanks
[Nook Color General] Taosaur:
Doesn't matter, as long as you have the old-style 1GB /data, 5GB /media partitions. The first couple steps wipe out whatever you previously had installed, anyway.

As long as current Phiremod is based on a fairly recent CM nightly (anyone know the #?), it should have multiboot. If not, use the multi-boot and stock-to-dualboot files in this thread's OP.

Doesn't matter, but if you already have an SD, I'd stick with that.

As far as backups, you can make as many as you like and they will each be in a separate folder labeled by date, and CWM will ask you which one you want to use. I would backup your current CM7, then after you flash Phiremod, boot to CWM again and do backup & restore > advanced restore > /data. I can't guarantee it will work moving from CM7 to Phiremod, but I think it should. You might want to wipe cache after the restore, and I would flash gapps last of all.
[Nook Color General] futr_vision:
I don't get the reboot with the rhythm method. Without the CWM SD card in you get to a factory reset screen. With the SD card in it appears to boot back into CWM as it usally does. Did I do something wrong?

NOTE: I think there are a couple of places in your instructions where you might want to include "remove SD card" if CWM is installed on a SD card. Just a thought.
[Nook Color General] futr_vision:
OK. I opted to go with CM 7.0.3(last stable release). For whatever reason when I get to step 14 it reboots and I see the (multi) U-Boot 4.0 on the scree, then blank, then ANDROID. After that I get the CM7 screen with the arrow circling the android on the skateboard and it just sits there. Nothing else happens. Ideas? I also can't figure out how to get into stock 1.3.

Thanks
[Nook Color General] Taosaur:
Ah, I was using internal CWM--not having to apply the rhythm method would be one benefit of using a CWM card instead. I'll amend.
[Nook Color General] Taosaur:
I don't think the current boot files are compatible with 7.0.3. You need to grab a nightly--I'm on 176 right now with no problems.
[Nook Color General] futr_vision:
Thanks. I figured that out. I grabbed the most recent nightly - 177 and was able to boot into CM7 without an issue. I did hit a bump where I got the prompt "Booting into alternate..." but it never booted into the stock 1.3. I flashed it again and that seemed to fix it.

I was also successful in restoring the data from my backup. I guess I need to flash gapps now to get the Market running right?

One question. I think I may have seen this somewhere before but is there a way to reboot when in stock 1.3 to get into CM7 without having to shut down and remove the SD card?

Ok. I lied. One more question. I've been doing on this on a 8GB SD card. I recently bought a 16GB SD card. Can I just copy over everything from the 8GB card to the 16GB card? I recall when I first created my CWM card that I chose the 8gb version. Will that be an issue?

Thanks again for all the help. I needed to figure out how to do this before I messed with my wife's NC :)
[Nook Color General] Taosaur:
You can pop out that CWM card permanently, or at least until you want to make a back-up or flash an update. You were just using it to get set up; now you can pop a regular SD card in there and use both installs to the fullest. If you shut down B&N stock and power on again, it will boot into CM7 by default. If you hit both volume buttons together while it's booting, it will boot into alternate (B&N). No need to put the CWM card in there again until you want to boot into CWM.
[Nook Color General] :
I tried to follow this procedure today.

Everything seemed to have worked fine... Except that when I try to boot into my alternate partitions, it just hangs. I can see that they are there (in a separate utility that lets me mount any partition to the computer)... But they simply won't boot. Unfortunately, I'm in windows right now so both my system partitions just come up as unformated atm. I may try to boot up linux to poke around tomorrow... but I'm not even sure I would know what I'm looking for.

Partions list as: (in NookColorUMS from these forums)

Boot

Rom

Factory

System - default

Data - default

Dual-boot System /system

Dual-boot Data /data

Any suggestions?
[Nook Color General] Taosaur:
Which procedure is "this" procedure? If you want to use a CM 7.1 ROM, both the multiboot and the move-to-dualboot zips in the OP are outdated. Jasoraso supplied an alternate method and I spelled it out step-by-step earlier in this thread, if you follow the "Dual Boot" link in my sig.
[Nook Color General] :
I followed the one in the first post.

It had a couple of edits, I figured that it was being kept up to date by the OP. I went through the first few pages and then check the last page... didn't see any new steps. That's my fault for being lazy I guess (was doing this at almost midnight last night).

Thanks for the answer. Looks like that explains why I was having issues... Now to go try this again, hopefully more successfully.

:)

*edit*

assuming that the partitions are already setup from trying the steps in the original post, would I need to run the remove dual boot script then re-run the prep dual boot script? It would seem like there would be no point to, but figure I would ask since there's no mention of it.
[Nook Color General] :
Alright, I followed the instructions in the post linked in your sig.

Everything says it completed successfully. CM7 boots up fine. However, when I try to boot into the alt config, the CM7 boot screen says "Booting into alternate configuration" or whatever the exact wording is.... but then it just goes black and reboots. Almost like it's just not finding the files for the alt boot.

Should I just re-try flashing everything again from the start, or is there a shortcut from this point?

*edit*

Just booted up ubuntu...

Partition 9 (dual-boot System) mounts up fine, and looks correct as far as what I would expect to see there.

However, partition 10... the dual-boot data one mounts with a bad superblock error.. So, I guess I need to figure out some way to format that partition and retry the whole process?
[Nook Color General] Taosaur:
If you read back from my "guide" post, I had a couple of failures identical to yours. All I did between attempts was restore my nandroid backup, which I doubt undid the partitioning, and then I did run the dual-boot prep again in the subsequent attempts with no adverse results, and without running the undo zip.

I didn't mention it in the guide, but because I'd met with a couple failures already, before flashing the 1.3 update in step 13, I booted into both partitions to make sure they were working.

I wouldn't overthink it--just try the process again, checking that each step worked along the way.
[Nook Color General] sma350:
Dual boot CM7 and BN 1.3 Market error android.process.media

Why is it that some of the dual boot instructions suggest a format system, data, cache after the "Froyo to dual boot" install but this set does not? I have tried this process both ways but get the same issue. I have also tried the OP directions but with these files and have the same issue.

I completed this process once and CM7 boot worked but B&N 1.3 boot did not just hung up. Restarted the process at step 1 and now both work but Market will not down load apps and widgets, controls are missing from home screen in CM7. USB debug is on and I tried Fix permissions. Error: process android.process.media stopped unexpectedly pops up and requires Force Close. Using CM7 nightly 177. Also tried Phiremod 6.3 and it freezes with Google and spinning gears on screen. Matter of fact CM7 might have worked up until i tried Phiremod instead the second time arround. now the 4th and 5th I am getting the same issue every time.
[Nook Color General] Taosaur:
I'm not sure what you mean by "controls are missing from home screen," but all forms of CM7 are having issues right now with the market listing our device as incompatible with many apps, hence not offering download links and not updating. It's fixed by setting dpi to 160 and clearing market data, and clearing market data again whenever the problem recurs.

If that install was otherwise stable, you may have borked it with the steps you took afterward. I've also seen some trouble reports with nightly 177, and am sticking to 176 for the time being, myself.
[Nook Color General] thunderwagn:
I am thinking Phiremod is not supporting multiboot?

I understand the multiboot file, but which stock to dual boot file are you refering to?

I can go thru each step. Boot into stock rom and register. Success.

Then install Phiremod, connect wifi. Success.

Boot into stock BN rom 1.3. Unsuccessful...

I can get into phiremod just fine, but cant' get back into the stock rom. It says its booting into that partition but doesn't....
[Nook Color General] thunderwagn:
Ok. Finally got dual boot to work on both partitions! What FINALLY worked was in between steps 12-13, I booted into cm7 (#176) got wifi, shut down and booted into bn on partition 2. Shut back down and did the bn dual boot 1.3. Went back and booted into each again to double check. All is good and stock nook rom is updated to 1.3!

Now I will be going back (possibly against my better judgement lol) and doing it all over again, with a Phiremod install.
[Nook Color General] Taosaur:
Hmm, maybe booting into CM7 after the initial install IS necessary? I'm not seeing why it would be, but I did it, too, on my third, successful run.

It's hard to tell looking at Phiredrop's two sites, but I think his current Phiremod/MIUI is still built on CM 7.0, which would not support the multiboot in my post. You would have to use the eclair-to-dualboot zip that ikingblack posted in the OP, which will rename the boot files in keeping with j4mm3r's multiboot menu (not the one in CM7.1).

ETA: I made a couple changes to my "guide" post to reflect that Phiremod (which seems merged with MIUI now) won't work, but should work with the older files in the OP, and to add a reboot to both partitions before updating to 1.3 (really wish there was a plain, CWM-flashable 1.3 zip floating around to cut out those steps).
[Nook Color General] Taishan16:
I followed your instructions exactly to establish the dual boot, which worked so thank you for that, but I too am having problems with the android.process.media message constantly popping up and not being able to access the market. I feel like I have tried everything so far, including clearing the cache and Dalvik cache, and trying multiple versions of CM7, and still the same issue. I even followed someone else's advice and tried partitioning the sdcard and using the simple2text app, but couldn't get the app to download either.

Its really frustrating, because everything was working fine before I added this dual boot method.

Is there anything else I can possibly try? I started getting the error message even when I followed all of the steps and left out the apps market, so maybe there is something I am overlooking?
[Nook Color General] thunderwagn:
Well, I have found (at least for me) Phiremod 6.3 doesn't work. Phiremod 7 test v2 DOES work! The issues I am plaqued with now are force closes. Even going to cm7 #176.

Pretty much the same issue. I have tried several ways to no avail. I have been flashing gapps last thing. This has gotten so frustrating, at this point I am about to ditch the dual boot. The other frustrating issues is that if I have my sd card in, it always boots to that (cwm). I don't want this to conquer me, but have about exhausted my resources lol.:mad:

and thanks Tao for all your advice.
[Nook Color General] Taosaur:
lol, updated again to reflect the Phiremod data. I wish I could help with the force closes, but I haven't seen those since I was going back and forth between CM 7.0.3 and 7.1 on SD, months ago.

I started with a CM 7.1 nightly (around 165) and CWM 3.2.0.1, both on eMMC. I made a nandroid backup, tried the process once cutting some corners, couldn't boot into the second partition either time, restored my nandroid backup. Tried again, cutting different corners, same result, restored my nandroid backup. Tried again a few days later, very methodically, and was successful.

At no point did I undo the dual boot partitioning, and I ran the prep-dualboot.zip again for each attempt, probably doing nothing (it certainly didn't take as long as the first time).

There were no issues with installing a more recent nightly (176) but restoring /data from the older backup. It was actually a couple hours before I realized I needed to reinstall gapps.

That all seems inconsequential, but it's all I left out of the steps in the earlier post.
[Nook Color General] thunderwagn:
I have been very methodical to the installation. I have no idea what is wrong. I get the exact some force close errors from phiremod and cm7 so I am breaking something at some point I guess. I don't know how or what. I have even been undoing the partitions before starting again. Basically start each time from scratch. the one thing that I have not done that I have seen posted in several places is to format system, data, cache after the froyo dual boot and before flashing the rom. I am going to try that now...

update: Went into both partitions before flashing the 1.3 update. No force closings and everything good. Now I will go back and flash the bn 1.3 update, and check it out. Then go back in and flash the phiremod gapps file if everything is still good...
[Nook Color General] Taishan16:
So far, have you been successful with this addition?
[Nook Color General] Taosaur:
I can't confirm or deny it, but this guy is claiming there were some script errors in jaso's 1.3 update file, and put together an alternate version: http://xdaforums.com/showthread.php?t=1253525

Jaso's file worked for me, and I don't see how it could relate to force closes on the other partition.
[Nook Color General] Taishan16:
Thanks for the info, Taosaur. I'll try it when I get home to see if this could be it.
[Nook Color General] thunderwagn:
Hmm, seems part of my last post above is missing? Very odd. I had updated my post after each new step...

Any way, Tao, I have not seen or read of error's, but I have seen posts and read about there possibly being more than one version of the 1.3 update?. Not sure. After I started doing boots into both partitions and making sure I was kosher, BEFORE I applied the bn 1.3 update, I never had a problem with that partition.

And I agree with you Tao, I couldn't see that there being a problem with that particular bn 1.3, causing issues on any other partition.

My main problem was after all said and done, getting constant force closes on my Phiremod or Cm7 rom. Never any issue on 1.3. This got me to reading back once again and noticing that on some sets of lists that people did (like the op, and jasoro) they performed an additional wipe right after flashing the froyo dual boot.

So after did format: system/data/cache, I had no issues at all with force closings.

For me, that was key. I wish I had all the hours back on going over and over everything and trying to get it to work lol.

Everything is working just fine now. For those interested, here is the link to Phiremod. I had NO LUCK with 6.3. I am using Test Release v7 Test2.

https://sites.google.com/site/phiremod/nook-color-roms

You will need to extract the files with something like 7zip. Place the extracted v7 test 2 rom and phiremod gapps onto root of sd card. I did not flash his launcher pro zip, so can't comment on that. If you know how to use and set up launcher pro, I don't really see the point as its easily themed...;)

Taishan, Yes its working great! My advice would be to perform the remove dual boot zip, and start at step 4. After step 11, go back into mounts and storage and format: system/data/cache. Don't reboot till after flashing your rom of choice (step 13). Continue on with regular instructions.

---------- Post added at 05:21 PM ---------- Previous post was at 05:04 PM ----------

One other thing I would like to add. After everything was said and done I reformatted my sd card back to factory settings for a nice clean slate. I have all the files and my original nand saved on my computer. I have a 1gb card with my bootable cwm on it if I need it. Also the problem I was having with my sd card booting first was solved after seeing this post:
[Nook Color General] Taosaur:
Hmm, it makes sense to do that, but I know I only wiped once, in step 4, and came through just fine. I added the following to the guide: "If experiencing force closes, wipe system, cache and data again (step 4), then re-flash CM7 (step 12)."

It doesn't seem like it would be necessary to undo the partitioning and start over.

Actually, I'm going to add the wipes in as step 12--it may not be strictly necessary, but it can't hurt anything, and if it saves anybody headaches, it's worth it.
