Boot Loop - Help Please

I've had my NC rooted for 3 weeks. No probs. I decided to update to 1.0.1 to see if wifi was better and so I entered the adb command to force system update and all seemed to be well. After that it went into a boot loop.
I forced another "update" by powering down 8x during bootup. It reinstalled and then same problem. I then tried the directions at nookdevs to fix boot loops. I couldn't ssh into the NC, but to my surprise I could use adb, but I can't do the listed commands because I get "permission denied".
I did an adb logcat and I get nonstop info going by, mostly looking for stuff that shouldn't be there anymore, i.e. apps I loaded when it was rooted. Dalvik cache??
So, long story short, I've tried a system wipe 4x now and I'm stuck in an endless boot loop BUT I do have adb access. What now?

Haha. Good call. That did work. Bigtime brain fart. Trying all the hard stuff and not the easiest. What's the diff between the two methods?

Head over to Nook Devs for the breakdown of the two.. Both methods are requied for using the newest AutoNooter... Glad to hear the device is still in working order.

Stuck in Boot Loop
Noob here with a problem. I’ve had my NC rooted for 5 days and the rooting went well. I had all my favorite android apps up and running. However I was experiencing random reboots (2-3 times per day). So, I decided to unroot and let the 1.0.1 update install and then I was going to use Auto-Nooter 2.12.18 to get everything back.
I did the 8X reboot thing and after reloaded, the NC went into a boot loop. The first thing I tried to do was the n, volume+ and power button. It simply went back to the boot loop.
I immediately put the auto-nooter sdcard in the NC, plugged in the usb to the pc. As opposed to the other times I did this, I got no visual indication that the PC recognized or activated the NC. I waited the full 5 minutes and removed it. The boot animation had changed, but the NC stayed in the boot loop.
I then searched and found this on nookdev.com (nookdevs.com/NookColor_Fix_Boot_Loops ). Following the instructions there, I installed putty.exe in the same folder as adb.exe. Putty would start and the session window would open, but I could not type or paste anything into the ssh screen. I assumed I had a bad download so I redid that and the install – no luck. I then searched and found another site from which I could download putty.exe, same results.
Before I ejected the NC I opened the command line window and I did adb devices and it came back with nothing. So now my NC is not recognized by the PC (and was before all this).
Can anyone point me in the right direction? Any help with the putty ssh screen issue? Any help will be appreciated.

Out of desperation I downloaded putty.exe again and it worked this time. Using the script on the nookdev.com website, the NC booted. I then did the data wipe and the 8X reset. I'm now back to stock (mostly) and I'll see if it updates tonight. If not, I'll force it tomorrow and don the new auto-nooter.
I'm learning!!

Glad you fixed yours too. This device is nearly impossible to brick unless you deliberately try to. Definitely easy to undo hard work, but hard to brick.

I have the same problem. Minutes after rooting with autonooter, my Nook restarted and I didn't even set up ADB access. I tried reseting several times with no luck Please help!!

Mine is currently stuck in a boot loop as well. I did not update to the newer firmware it auto-updated and jacked everything up. Pretty upset right now.
I know I can reset the device but I need to get the data from it first. I have the entire storage full of data that I need. It will not boot at all and if this gets erased i'll more than likely end up returning the device and purchasing something that I won't have this problem with every update.

Unfortunately, there aren't many devices that will automatically backup all your important data to external media without you having to take some action on your own to set that up.

hey guys i'm noob here yesterday i rooted my nook color and everything was going fine until i turned it off when i tried to turn this again i couldn't so i took the sdcard off and tried again it powered but now i'm stuck in the grey 'N' screen, any idea on how can i fix this?

Well, I'm not an expert, but I have been through this kind of thing. I would think you have two possibilities. One would be to put the nooter sdcard back in and hook it to the computer again. If it isn't very corrupted, it may automatically reload from the nooter sdcard.
If that won't work, then I think it's time to do the 3 finger data wipe and then the 8X reboot thing. You can then redo the nooter sdcard thing.
Good luck.

EXACT Same thing happened to me and a friend when using autonooter and 1.0.1. I think there is a problem with autonooter or 1.0.1 messing up the booting process. I wonder whats wrong So I was able to do the 8X reboot thing and get back to stock 1.0.0 and from here I'll try to attempt to use autonooter for 1.0.1. But I'm staying with 1.0.0 until Froyo next month.

thanks! the 8x thing worked good, I did the whole auto noot process again and it works at all except by this market issue

Help stuck on grey n screen and can't get out

I'm stuck at the grey N screen and I can't get out. I just got my NC today, updated to 1.0.1, used the latest Autonooter, followed the instructions to a T, everything worked great.
I left the SD Card in (didn't know you were supposed to take it out and reformat it, none of the instructions were specific about that). I was playing with the unit, everything was working great and decided to reboot it because I saw there was a custom animation and I wanted to see it (didn't remember seeing it the first time around). Now the thing won't reboot. It just gets stuck at the grey N screen. I've tried the power + home method and done the factory resets 3 times but when it resets it still hangs on the N-screen and won't boot.
I'm at a loss here. Some one please help.

Did you try taking the SD out and then booting? It'll keep trying to boot from it as long as nooter is on there.

I'd say interrupt the boot 8x (powering down will do) to initiate system restore, then re-root.

Edit. That fixed it. Thanks. Man do I feel stupid. I thought the 8x reset and the 3 button method were the same. Apparently not. I'll try this again a little smarter hopefully this time.

Thank you for this thread. I thought I just bricked my 2 hour old nook. I stupidly restarted it after root with the nooter card still plugged in. Then I couldn't figure out why it was taking so long for the screen to turn on, so I kept pressing the button and then holding it. Then I realized the card was still in. Took the card out and tried to boot it, but it hung at the 'n' screen. The 8 interrupted boot method saved me from my stupidity though. Thanks.

Same here - left the card in...
8x reset and then a home and power reset cleared me up. Then update back to 1.1 and autonooter 3 again.
Loving it ever since.

hey
im having the same problem i did the factory reset to and nothing
wats the 3 count and wat else can i do

So what to do when factory restores and stock installs fail?!
OK... reviving this thread since it's my exact problem but I've been unable to find resolution. I've been searching everywhere for what to do next but nothing seems to be working.
I'm helping my buddy get his nook working. He said he was updating to 1.4 and when he rebooted it, it froze on the n screen. He plugged it back into his Win 7 machine to try the update again and it wouldn't mount as a USB device.
After a bunch of reading and fiddling, he built an SD card with ClockworkMod and installed in on an SD card. Or so he thought... he hadn't made it bootable. Over the phone, I walked him through restoring the image to his card and then it booted.
CWM comes back with a pile of errors. Specifically,
E:Can't mount /cache/recovery/command
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
When trying to format /data and /system, we also get errors.
We've downloaded various factory restore zips and tried installing them but they install (successfully according to CWM) and we reboot only to get stuck at the dreaded n screen again. We've done the 8 boot interrupt restore and get and error to call support (nobody answers this week) and done the regular power/+/n restore and it completes but leaves us again on the n screen.
Can anyone tell me the significance of these errors in CWM? It's the only thing different from all the tutorials and video walkthroughs we've followed and although we've seen these errors in other posts, there's never been a good explanation of them and how to resolve them if necessary.
Also, what is the latest version of CWM for the Nook Color and where do I find it? Is there an official site for CWM? Seems like people are just linking to older versions and sources all over the place with no common "go to the CWM site and get latest build of CWM." The latest I've found is 3.2.0.1 in a post back in August 2011.
Thanks in advance! Hoping this gets us over this hump and helps anyone else in the in the same situation.

Solved it...
I've managed to solve the problem I outlined above. I'm not at home right now, so I'll post the specifics once I can get back and post the links and images I used to get this working.
Note that I had no concern for the data/books/apps that were on the device originally. I just wanted it working again with stock 1.4.1.
Basically, I noticed that after restoring to 1.1, the initial screen said "welcome to the future of reading" and then when I updated to 1.2, it said "read forever" so I knew the updates were at least doing something. I now needed to get rid of the errors in CWM 3.2.0.1 so started looking for something to blow away corrupt (?) partitions.
I found a post that had two zip files and it said they repartitioned the nook entirely. I hoped they would blow away my corrupted partitions by rewriting the partition table. I ran one, and it forced me to reboot. Then I ran the second and rebooted. It loaded up, got to the n screen and paused just long enough for me to lose some hope and then flipped over to the nook color boot animation. Yah! Progress!
Tried to register the device using my own bn.com account but wasn't successful. Turns out that you need to either use the original registered account on bn.com or unregistered the nook from his account, but since the error shared the same wording as previous failed factory restores (but this time in the nook registration interface), I assumed it was something locally. I came across a post in the searching that mentioned the need to unregister the nook from the original account to register it on another.
While trying to figure out what to do, I found a 1.4.1 signed stock image that also reconfigured the restore on the device and worked through CWM "install zip from SD" rather than using bn.com update zip via usb (i was still having trouble accessing the nook via usb at this point).
I downloaded the stock cwm 1.4.1 zip and installed it through cwm 3.2.0.1. It booted and then I saw the intro video on the nook registration page had a different woman. I got my buddy to send me the email and password he registered the nook with and the registration process was successful. I now have a working stock 1.4.1 nook color to return to my buddy.
I'll post the actual links to the posts/images that I used once I get home.
Hope this helps others!

I'm also getting the E: Can't mount / errors.
Will try this when I get home.
Also i'm just realizing now that i am using an older CWR v3.0.0.5, so that might be my issue also.

Mooseroo Could you please post links used to fix this issue

Try using this version of CWR. Just remember you can always choose a recovery image smaller than or the same as your SD card but not larger.
http://mrm3.net/blog/2011/03/11/nook-color-updated-clockwork-recovery-bootable-sd/

this is not working. same issue with nook 1.4.1 and CM7...hangs at "N" or goes black with CM7

Have you check the MD5 of all your files to make sure you have good downloads? It is frequently a skipped step but one of the easiest and first things you need to check.

Mooseroo - where are you?

nook will not fully reset

Hey guys need help. I have a nook running 1.01 and used autonooter the owner of this nook had used the wrong email address upon initial setup and of course could not purchase any books from bn store.
I did a deregister and erase and no option was given afterwards to register the device.
So I did the 8 failed boot loads to get the nook back to factory. It still won't bring up the wizard to register the device.
Did the 8 failed boot loads again and same story.
What else can I do?
Thanks!

3 finger reset:
hold VOL+, N, and PWR until it shuts off. Upon boot, it should give you an option to factory reset.

[Q] I have a headache...

I purchased a nook color the other day and successfully rooted and used it for a few days. My youtube would not open so I reinstalled, it ran once and then failed to open again so I gave up on that issue. In reading about youtube app I found that you could get the new market app. I could not get it to install...and in trying multiple things I accidentally deleted my original market app.
I could not get it back so I whiped my nook color and reflashed autonooter. I got all my apps back but I get a connection error when trying to access the market now. I added my account via youtube which again opened once to allow me to sign in and now fails to open.
So I decided to try to reset it back to the way it was out of the box and start from scratch.
I tried the adb 8x reboot method.....it just reboots the nook as it normally would. No bootloader or install screen.
I tried the button method. It works once or twice then it goes through the entire boot. I did it for a half hour and used counts to verify I was doing the process correctly and no matter what I did I could get it to fail boot once and one the second or third it would always bypass and go through with boot even with my finger on the button.
I also am running windows 7 64bit and I cannot get my computer to see "nook" in the device manager for more than a second and it auto installs as a storage device. I've tried to "uninstall" the different devices and last night I was able to catch the "nook" in time to install usb drivers manually but when I reset the nook today my PC no longer see's it again. I was wondering if there is an easier way to install the adb device.
Thanks
UPDATE: Somehow the ADB way to reflash worked the second time I tried it. I also changed some settings in the development menu to fix the device manager issue. I'll update again if I can use youtube and the market.

I don't know what to tell you about everything else but for ADB I would highly recommend adbWireless... it works great on my NC and I never had to install any drivers.

To reset I used the button and counted slow to 15 after the screen gose off each time it worked for me. Good luck

[Help] Nook Pseudo-Boot

So, I was running CM7 no problems. Then one day the ax just fell. I tried re-flashing the ROM and it hangs on the boot animation...so, I removed CWM, made a bootable CWM SD and flashed a few different "return to Stock.zips." One finally worked, but when I connect to Wifi, it says it can't connect and shows that my device doesn't have a serial number or a model number, so I can't get beyond that screen, and it is on version 1.0.1. So I tried using the CWM SD again to update the Firmware. When I did that as soon as I turned on the device, it locked up on a screen that says, "Install Failed, please power Off and the Back on again." So I tried completely wiping and re-installing CM7 to eMMc, and now, again it just hangs on the boot screen.
Oh, and 8 boot interruptions doesn't work for me and when I try holding the power +N keys I go directly into the "Install failed please press off and power back on to try again," screen.
My head is going to explode. Please help. I think my next attempt is going to be trying to flash an alternate kernel.

Hey I tried this, and when I flash the .zip, as soon as the device powers on it goes straight into the "install failed please turn off device and the turn back on to try again," dialog. On this screen it is black with a white stenciling of the NC. I have grown to despise this screen.

Also, anytime I have tried to factory reset, it goes directly into the install failed screen.
I have managed to get into the stock 1.0.1 homescreen by bypassing the Out of Box Experience, and even when I try to Erase/Deregister there, it stops and says device not registered, and therefore it cannot wipe. Also, when I check device info, every single one has red 000000000.
I suppose that since I'm at least to the homescreens I could try ADB, because it wasn't working either the last two nights.

Also is there anything in the LOST.DIR that could help? What the hell is a LOST.DIR?

So, another interesting thing here...whenever I go to install ADB the softkeys show up in the status bar, like its already rooted and running the stock 1.0.1 launcher bar, as soon as I unplug the USB, they disappear, so I can't even enable debugging.
Also, the NC isn't showing up on the ADB device list.
