Now I'm pretty sure my CW is gone...lol I'm trying to boot into CW and it either goes to the N screen or a install failed turn off and turn back on. I think uRecRam moved to /boot now I have to move all other fiesl maybe..
[Nook Color Android Development] straby187:
Sucesss!!!! You have to

mount /dev/block/mmcblk0p1 /system/boot/

then you root explorer to move files from boot.zip to boot folder
[Nook Color Android Development] samuelhalff:
Well that's not mandatory. All you need is an existing folder.... anyway, glad to hear you found a way back. Can you now restore?
[Nook Color Android Development] GoochyPuppy:
Ditto: How to put original Nook Color recovery back after CW Recovery install?

Glad I'm not the only one asking this, as I was feeling a little stupid. Perhaps I just like to have company.

Clockwork Recovery and the current clockwork mod for Nook Color works "ok", but now I can't figure out for the life of me how to restore back to the original stock recovery (and thus, a TRUE factory reset capability ... right?).

Unless I don't understand this right: CW recovery replaces the Nook Color standard recovery process, right? Is it just moved somewhere on the device? Or can it be downloaded from somewhere?

I wish CW recovery had self-uninstall as an option...; but appreciate your help here.

Thanks!
[Nook Color Android Development] straby187:
Restore... I've restored, auto-nootered, flashed CW and ready to do more damage with "She's a Screamer" lol

Trying to wipe cache, I get

E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't mount /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

and if I try to wipe Davlik Cache, I get

e:unknown volume for path [/sd-ext]

I've asked this a few times...I can't believe someone here can't help with this
[Nook Color Android Development] eyecrispy:
I got the same errors when i wiped cache. But it said wipe was successful. I don't even have an option to wipe Davlik Cache. Where does one find that?
[Nook Color Android Development] Socrguru:
I get the exact same thing, and would like to ask the same question - what's up with this?

ClockworkMod also freezes whenever I try to wipe Dalvik cache. Scares the bejeezes out of me, but I can shut down and reboot by holding the Power button. Any thoughts on this as well?
[Nook Color Android Development] Divine_Madcat:
In regards to the "errors", they are nothing more than CWM looking for common files that it thinks should be there, but aren't. There isn't actually an error, and the clearing does work.

Dalvik cache can be found under the advanced section.
[Nook Color Android Development] bdcrim:
Lot of folks, including myself, are having success with installs not wiping. I flashed three different kernals with no wipe. Sounds gross, but it works.
[Nook Color Android Development] paleh0rse:
1.01 auto-nooted with Quickie 900mhz, ROM Manager, and CWM Recovery installed, and both my wired and wireless adb still work perfectly. :)
[Nook Color Android Development] Socrguru:
Thanks, I'll just cross my fingers and give it a try!

Any idea why it freezes (for in the future, when I might be trying out different ROMs and need to wipe Dalvik)?
[Nook Color Android Development] painter_:
This question was answered in this post a few pages back.

In a nutshell /sd-ext does not exist on the Nook Color. It is used as part of the apps2sd process 2.1 and earlier versions. apps2sd is not a native Android app and has not been ported to the Nook. Apps2sd required a partition on the SD card to be formatted using the EXT file system. This partition was linked to /system/data on the phone and "tricked" android to install the user programs on the SD card.

Clockworks retains the code to backup the EXT partition as part of the nandroid process. This is why you are seeing the error.
[Nook Color Android Development] zappaziz:
True here too. With me my touchscreen accuracy was all over the place the first flash of 900...flashed 900 a second time, no wipe or CW restore, and it worked like a charm.

And I tried the lcddensity to correct the accuracy but couldn't get it to save the changes. I can click the save(restart) button but it doesn't do anything.
[Nook Color Android Development] bdcrim:
You are 100% sure it freezes? I have not wiped dalvik on the nook but I have on my cell. There appears to be no action when I do that, but I trust it wipes. I don't want to insult anyones intelligence, but you have figured out how to navigate backwards with the power button from the dalvik screen to reboot?

Sorry, I should have read your other post. Apparently you were all over the power button to reboot. I would not have any additional thoughts.

[Nook Color Android Development] Socrguru:
Oh well, I'll just live with it and avoid the Dalvik cache (from my understanding CWM has always had some issues with clearing Dalvik anyways - at least in the past).

And yeah, I let it sit about 10 minutes before trying to press a button and it wouldn't respond to anything but holding the power button. Even tried reinstalling CWM through Rom Manager, nothing different.
[Nook Color Android Development] Divine_Madcat:
I can confirm i have had this dalvik clearing lockup as well. It said it was clear, but then solidly locked up.....
[Nook Color Android Development] tboothie:
Same exact problem for me as well... Really had me worried, especially when power off wouldn't work either. Interestingly, what I did was plug in usb and then issued 'adb reboot'. I didn't realize that adb would work while in recovery, but it does.
[Nook Color Android Development] davenull:
Is there any way to use the actual Nook android install to flash the original recovery?
[Nook Color Android Development] clottier:
Not seeing this topic I loaded clockwoorkmod, did a backup and went about my business with my nook and went about some playing around with my rom. I knew the day would come that I would screw something up, at some point, and that time struck me last night.

Could not boot and the darn thing started back from scratch but my screen would take forever to see my taps. Somehow I managed to get into the clockworkmod recovery after hitting restart a number of times and 20 minutes later my nook is back to my last backup time.

Thank you clockworkmod! Saved me from myself....

[Nook Color Android Development] DrewLGT:
so i tried to install the overclock kernel via CWM. i installed the zip, but i was under the impression i need to run the update.zip for the changes to take place. CWM tells me the file could not be found, and i just have to reboot.

any ideas?
[Nook Color Android Development] eyecrispy:
If you named the overclock kernel to update.zip then you could do that. But the easiest way is to download the kernel zip file to your sd and then choose install a zip file from the CWM menu and navigate to that file and flash it that way.
[Nook Color Android Development] DrewLGT:
i was under the impression you needed to run update.zip anytime you flashed a zip from your SD card
[Nook Color Android Development] moonpie28:
That's without Clockwork...
[Nook Color Android Development] Geezer Squid:
Moonpie is right. Listed below are the instructions. BTW, you should do a fresh backup prior to making any changes.

Installation Instructions [ClockWork]

1) Download the ROM/Kernel/Theme of your choice and place somewhere on your SD Card

2) Reboot into ClockWork recovery

3) Scroll down and select “Nandroid”

4) Select “Backup”

5) After backup is complete

6) Select “Install zip from sdcard”

7) select “Choose Zip from sdcard”

8) Navigate to where you placed the ROM and select it

9) On the "Confirm Install" screen scroll down and select “Yes”

10) Your ROM will be installed

11) Reboot from the main screen of ClockWork Recovery

Hi All,

We have had ClockworkMod Recovery 3.0.0.5 for about a week now and no custom roms. I would like to say I’m impressed with speed of development on the nook color and the devs here at xda.

I would like to setup “update.zip” file for installing custom roms as well as stock b&n rom via CMW to internal emmc.

I have been collecting information on installing nookie froyo to emmc and other stuff on update-script syntax for update.zip files.

Anyone interested pooling resources or have some input?
[Nook Color Android Development] gtkansan:
Hey Guys. Having a major problem.

Continuous bootlooping issues. Cant get to ADB and have tried the autonooter SSH method of resetting bootcnt. Several times in fact.

Anyway, only way I can get to ADB is through using a nookie froyo card and booting up in froyo. Is there a way for me to install clockwork onto the system while I am booted up in FROYO? Its literally the only thing I can think of to get back a recovery and hopefully restore my previous rooted nook state.

I even tried using the 1.01 install file from the nook color update to try to get it to just install a clean state, but no such luck and I am really stumped. Any help is majorly appreciated.
[Nook Color Android Development] camwinnn:
Yes you can use froyo to ADB fix it, I had the same bootloop problem.

I am hoping someone can help me out.

Last night, I tried to boot into recovery, and now I am stuck at the "Touch the future of reading" screen. The only thing I can currently do with my nook is boot into Nookie Froyo, off the SD card. I can't seem to successfully do a system wipe, because it doesn't respond to me trying to turn it off once it gets into the loop. If I want to power it off I need to insert my Auto Nooter card, then it stops trying to boot.

I can't get into recovery. I can't get it to show up in ADB. I can't really do anything at the moment.

Does anyone have any ideas?
[Nook Color Android Development] gtkansan:
Didnt work. the folder needed RW is /media not /system/media

SO I installed root explor through adb (ADB install rootexplorer.apk) while booted up into nookie froyo.

Then used root explorer to set RW on /media and /system so I could get the recovery file to transfer over to the device. New instructions used:

Save this file to the androidsdk/tools folder on your drive:

http://koush.tandtgaming.com/test/clockwork-b3-nook-uRecRam

adb push clockwork-b3-nook-uRecRam /media/

adb shell

su

mkdir /system/boot/

mount -t vfat /dev/block/mmcblk0p1 /system/boot

cat /system/boot/uRecRam > /system/boot/uRecRam.bak

cat /media/clockwork-b3-nook-uRecRam > /system/boot/uRecRam

umount /system/boot

rmdir /system/boot

**** Note: I also had some issues with the above, since the /system/boot folder already existed. I used root explorer to delete the folder to ensure I wouldnt have any extra crap, but since it was made by installing clockwork earlier (for me) Im sure it wouldnt cause any issues.

**** Also make sure that once you are done with "adb shell" you only see one # symbol. I had an error where it would auto go in with Su permissions and I would have two # (i.e. # # ) and wouldnt accept commands. If that is the case just type exit to get back to one #, or remove the su command from the typed commands above.

Hope this helps others, certainly was a lot of work for me to get this going.

Install CWR from Rom Manager through NF booting from sdcard.
[Nook Color Android Development] samuelhalff:
Sn0wf0x posted an image of boot partition in a thread in dev a few hours ago. You need to boot into NF from uSD and dd the image onto mmcblk0p1 (boot partition).

Copy the boot.img onto the NC first, for example onto sdcard, then adb shell, dd if=boot.img of=/dev/block/mmcblk0p1

That will give access to a fresh boot partition. You will then be able to restore if you want to.
[Nook Color Android Development] camwinnn:
Lawl if it was /media then should have used just /media instead of system

The last part of the code just indicates the folder

So mount -remount,rw /dev/block/device/mmcblk0p5 /media

Glad you got it fixed tho.

Don't believe it's quite stable yet - dev still working on it. You might be better off following the "Monster Root Pack..." thread as that's a simple flash (once the dev fine-tunes it). Meantime, I'm staying away from it for now as it seems to boot loop a lot.

I installed ROM Manager, flashed recovery, everything went awesome. A couple of questions in regards to everything.

Just for siggles and giggle try this. CWM is picky with SD Cards and i had been having problems with it not seeing them.

Diskpart

1. Click on start orb and type 'cmd'

2. when cmd opens, type diskpart

3. after that type disk

4. pick your SD card

5. type clean

6. type create partition primary

7. type fomat fs=fat32 quick

8. type exit
[Nook Color Android Development] eyecrispy:
Thanks for the response.

Is Diskpart a Windows app? I'm running on a Mac. Would it work on a Mac? Also, what does this do exactly?
[Nook Color Android Development] bonzer2u:
fyi, just to clarify

step 3 = list disk

step 4 = select disk X (X=number identified in step 3)

if you clean the wrong disk, u wont be happy.....
[Nook Color Android Development] grandmasterlarry:
yeah its built into windows it cleans and reformats your disk. just doing a regular format in windows didn't work for me. I don’t have a MAC so I don’t know what you can use sorry...

And thanks for clarifying the steps. it wouldn't let me do MultiQuote on my work computer.
[Nook Color Android Development] bonzer2u:
Windows only, and another tidbit, if you leave off the 'quick' in step #7

it will do a full format which I prefer as it does a full wipe on the data and scans for 'bad' sectors, marking them unusable if found...
[Nook Color Android Development] eyecrispy:
Ok, so this will completely format my SD? I'll lose all my data on it?
[Nook Color Android Development] bonzer2u:
absolutely YES
[Nook Color Android Development] eyecrispy:
Ok, so suppose I save off the current data on my sd card. Could I copy it all back onto the sd once it's formatted? Or do you think it's something on my card that is causing it to not work right now?
[Nook Color Android Development] grandmasterlarry:
Yes make a folder on your Desktop or whatever you guys call it (mac) and copy it all back after. thats what i did and had no problems my SD card works like a charm now.
