NookColor reflashes itself back to stock?

something interesting happened to my NC last night. i was messing around with system apks, trying to get better access to the system settings. i copied Settings.apk and SettingsProvider.apk from the 2.1 emulator to /system/app the NC. they didn't work, so i replaced Settings.apk with the original, but forgot to replace SettingsProvider.apk. bonehead mistake. anyway, upon rebooting, the device was stuck in a bootloop. it would get to the white "Nook Color, by Barnes and Noble" boot animation, and just loop over and over. i tried the factory reset twice, but as i expected, it didn't help.
i decided to give up for the night, and left the NC plugged into AC power, bootlooping over and over, just to see if anything would happen. after about 30 minutes, i tried to shut it down by holding the power button. the screen went off, and i set it down. when i looked back a few seconds later, the NC was booting again. this time, it came to the screen shown in the attached photo. on the screen, it says "A new software update is being installed. This will take a few minutes."
the process finished, and the device booted up into a fresh, clean, non-rooted 1.0.0 installation! a real software update wasn't installed. it seems the device decided to reflash the original ROM on itself. can it be that the NC is smart enough to know when something is catastrophically wrong, and flash back to stock? either way, i'm happy to have my NC back in business

pokey and I were talking about this in another thread (though he's better at dissecting this stuff than I am). There's a counter for unsuccessful boot attempts, and after 8 it apparently flashes "factory.zip" from partition 3, which is a full clean factory dump.

This actually happened to me, sort of, two nights ago. I was messing around with system settings, but didn't change anything too important...or so I thought.
Shortly after, I was using my Nook, as it was working normally, and the initial setup screen popped up, said something about being unable to authorize my account, and then went ahead and factory reset itself,forcing me to have to re-root. Pretty annoying, and it was odd, since my Nook seemed to be working fine.

It may be worthwhile to make a modified factory.zip so devices wouldn't lose root, no?
I haven't yet encountered this problem, but it would suck to have to reformat my microSD card if this should happen.

Mine did this exact same thing too. I messed with the settings apks and then when I went back to the B&N home screen an error about not being able to authorize and the device needed to be reset. then it rebooted and performed a reinstall of 1.0.0

well there you have it. a nice feature, for the reckless
any idea where the counter is kept?
might there be some way to put factory.zip on the SD card, and force a flash? this would just be a parachute in case something gets too messed up for the failed boot counter to work.

This can be done manually too. Look on nookdevs.com for NookColor_UnRooting

That isn't the same thing. It only fixes a few things (like Ramdisk, obviously), while this thread is referring to a complete clean /system.

actually, in a quiet, unassuming box at the bottom of the nookdevs unrooting page, it does describe a method to flash back to stock. apparently you hold volume down (minus) while powering on. it's easy to miss. i'll break that bit of information out into it's own page.

Given this possibility, is there a way to backup a rooted NC so it would be easier to rebuild after an inadvertant flash.

Some of us noticed that "quiet, unassuming box".

This, built-in, mechanism seems like a pretty bullet-proof protection against bricking your Nook Color. The Nook Classic has a similar mechanism. I think it's a great idea and I wish all these new tablets had such a capability.

I'm loving the Nook Color but other things require the money right now so it's going back, for now.
I just did the Home+Power key combination and it did a reset. I re-registered the device to make sure Angry Bird and a few other things were gone and they are. I got a notice at the bottom of the home screen saying something about a software update and it just said I was currently on 1.0.0, I clicked it and it went away. But, in Settings and Device Info there is a Erase & Deregister Device option. When I click the option it says the following "This will remove all digital books and files, including side-loaded content, from this device. The titles you have purchased will remain in your B&N account." I find this interesting since it specifically mentions "side-loaded content" and I'm wondering if this also triggers the 'factory.zip' file and as a complete factory hard reset of files and all. I haven't seen it mentioned anywhere else so I thought it might be worth mentioning.
Cheers

[Q] Can't register after flash back to stock? Was I actually successful?

I'm having the same issues as takef0cusin above, arriving in a slightly different way. I was properly registered on 1.0.0 and used auto nooter 2.12.15. That went fine and there were no problems, but I decided to upgrade to 1.0.1 after some Wifi dropping issues. So I decided to flash back the the clean stock ROM.
I did the re-image holding down the power button 8 times, then I did the "three button data reset". Everything seemed to go fine, but it still started with the Logic PD Zoom screen and it never gave me the opportunity to re-register. Owner and Account are listed as unavailable. I then tried again using the "Erase and Deregister Device" method. Same results.
The new icons from the rooting are there, which makes me wonder if I actually had a successful flash back. I tried to register with the Gmail icon. It let me put in my email username and password. I acts like it is going to work, starts to load my conversations, then returns to the NC Home screen. I also tried to go through YouTube, but after registering I get "There was a problem with the network [401]". The Wifi still works, it still gets me the news, but the weather won't load because it says it there's location available.
What do I try next? I'm afraid to do anything because of all the warnings to re-register the NC first thing after any of these upgrades.
Thanks and Happy Holidays, OKMD

I've been through all this twice now. The second time was exactly as you have described and all I did was to redo the 3 button data reset. I was then able to re-register it.

Did it pop up to tell/ask you to register, or did you have to go looking somehow? Mine isn't asking and I don't know how to force it. Thanks.

If memory serves, after clearing data it comes up with screens where you select time zones, state, city, etc and then it asks for your user name and password. All this happens automatically after you do the 3 finger data reset.

[Q] rooted OK but now it continues to try to boot

I rooted my NC yesterday using the auto-nooter 2.12.25. Things seemed OK. I DLed some apps & used them. Got ADW launcher loaded and began setting it up for my preferences. The NC went most of the way through an update cycle even though I had already updated to version 1.0.1. However this time it never got to the green "n" and then it started cycling through the part where it comes up & writes "nook color", continues until the colors quit flashing & then starts back at "nook color".
None of the buttons seem to have any effect. I tried to follow the 'solution' entitled "NookColor Fix Boot Loops". I tried both the auto-nooter SD card and then when that didn't work, I tried the original manual nooter SD card.
Anyone have another idea to fix this. I'd really appreciate some help. A PM would be great or just answer here.

I had the same problem earilier today, I held down the power button until it did a complete reset (about 8 seconds of holding). It is working great since.

Thanks. I had already tried that, several times.

restore to factory and start again?

i have not tried any of these methods no need to but i do so much messing up
i guess eventually i will with that said this might be a long way around to your solution
read both carefully

Thanks, nookroot but this is not working.
Method 1 for unrooting - Holding those 3 keys together for over 30 seconds has no effect.
Method 2 for unrooting - I can't unroot with method 2 because the NC has to boot before I can go to settings.
Any other suggestions? In fact it seems that if it ever does power off, the only way to make it power on is to plug in its USB cord & this doesn't always work. When it does it just stats cycling. Sometimes it seems to just power up on its own and start cycling.
Whatever happened, since it's rooted I can't return it to B&N and I don't seem to be able to unroot it. Effectively I have bricked it even though many people say that's impossible.
Edit: something new just happened & I was able to go through the method 1 reset. It's booting now & looks like the B&N screen is coming up. I'm not sure how it happened. I'm going to leave it unrooted until I feel adventurous (or foolish) again.
P.S. Came back with version 1.0.0 SW.

[Q] Nook Color Random Restore (Autonooter 2.12.25)

Not sure if this discussion has already happened.
I have noticed twice since rooting my nook (with 2.12.25) that it has randomly restores back to 1.0.0 (or seemingly).
The first time it was just sitting beside me and it did one of its un-commanded restarts. I noticed that it was reloading the original 1.0.0 version. I lost everything and the nook was unresponsive after finishing. I followed all the hard reset rules and then upgraded to 1.0.1. I then autorooted again and reinstalled all apps.
Last night it did it again while I was using it. I was reading a book and then went to check email. I got an error message something like "invalid authorization" and that it was reloading the base software. I let it do its thing and go through its reboots. I also let it automatically update to 1.0.1 before I touched it. I re-registered it. Now when it loads it doesn't show the normal rooted nook boot screens. When I go into extras I see only the stock apps plus the additional ones that the auto-nooter loads (everything else gone). I tries to get me to log into LogicPD Zoom (Google) but it fails to load.
Has anyone else seems this?
Is there a way to re-load or fix the nook color install without having to go through the complete wipe process?
Once I fix is there some setting we can change to prevent it from happening again?
Thanks

After nootering the nook, I proceeded to load clockwork mod and made a backup of the OS. Now when it auto restores, I can reinstall the backup from clockwork mod by holding both Power and the Nook Key for five seconds when powering on.
Still don't seem to know how to stop the auto restoring though

Mine restarts too, has since I rooted it. Thankfully, there is no data loss, just an inconvenience. If there were a log being kept (like in other OSs), I could at least go there to find out what is crashing it.
Acts like a low memory restart, but that isn't what it is.
TJD

Wanted to add that mine does this also. It has happened 3 times in 4 weeks. Thank god for ClockWork it is not to big a deal now to restore. I wish someone could figure this out tho.

Mine actually randomly boots up (I'll have it off, then hear it start up a few hours later). Not sure it's related, but thought I'd mention it in case it turns out to be.

Mine used to restart everytime it went to sleep. Happens to alot of people. SetCPU and On Demand usually fixes it. There is like 2 or 3 of these threads in Q&A

Except they're talking about the system restoring itself, not rebooting.

It has to reboot to restore. Thought if you fix the reboot problem it would help maybe not... My bad

I'm autonooted on 1.0.0 and have never had an ota restore or update.

Have you guys made sure to rename the otacerts file after rooting?

There are several active threads on this. In my case it was a faulty power button. I went ahead and exchanged the unit. Replacement is 1.01 and feels like the case is sturdier. Might be imagining that. Check my other posts on the subject. Good luck.

Ok. Whaaaat? Rooted NC stopped working? (will re-rooting help?)

Picked up my NC 1.0.1 today. Rooted without issue. After having a Google Talk conversation, I lost access to Marketplace, and all Google Apps? Can't log back in?
Anyone else having similar issues?
P.S. My wallpaper was changed as well ?!?!?!?!?!
p.p.s. My browsing history and favorites are gone too? Please tell me an update or something was just pushed out. I feel like I just wasted a few hours of my life here.

My rooted 1.0.1 nook has problems as well. Gets authorization error and resets data. After restoring through the clockwork recovery, had it up just for 5 minutes before it automatically reset again. Lost all my apps, market access, youtube, etc. Don't know if this issue has been discussed before. May just have to go back to stock.

It appears that something is amiss. I cannot sign back into any Google Services.
Can't establish a reliable data connection to the server
This could be a temporary problem or your phone may not be provisioned for data services. If it continues call Customer Care.

Would a simple re-rooting solve the issue?

Same here. Was using everything fine Saturday. Turned on the device and in a few minutes I got an error, something about a problem with the registration and it said it was rebooting. It did and wiped everything of my rooted install except the market. Can't login to google account now.

I might add that I got my device it was at 1.0.0 and I rooted then reflashed to stock to upgrade to 1.0.1 and rerooted. Then I noticed after today's unexpected reboot/data wipe (the status screen during the reboot says it was wiping data) it again gave a message that it had just upgraded to 1.0.1 so I initially thought this was an issue with the device thinking the firmware upgrade was not quite done...

Mine quit working as well. Mine is a 1.0.0 that was auto-nootered. Everything was fine and I used it daily. Now it is a brick, nothing I do seems to make it boot. Every once in a while I can get the backlight to come on but nothing else and it just goes off again in a few seconds.

Rather than troubleshoot, I busted an 8 times reboot to go back to stock then re-rooted. Seemed like less headache, panic and stress.

If your NC dosen't boot at all. Try doing a dd of snowfox's boot.img in dev section. See thread for more info. You'll need to boot into NF from SD.

I have tried rerooting, and restoring through clockwork...it seems to always revert and bootloop. Although the reroot lasted a week and clockwork restore hasn't lasted 24hrs twice now.
Not sure what to do but My wife is ready to kill me! I'll have to go stock till someone finds a way to bust up this authorization or just wait I read some ROMs are being developed.

Have any of you disabled the otacerts.zip?
If you haven't it may be the problem.
I have and same on my wife's and neither of us have had any issue, and we use them daily.

I hadn't realized I should be doing this. I will try it. I am actually thinking that my first store purchase came w/ an update (my issue seemed to start right after a magazine trial purchase was made).
Thanks.

Thank you, I will try that. All the searching I did was for disable OTA NC and such but actually searching for OTACerts brought out many many threads that were archived on this subject... I can't wait to get home to try it!

I did not rename the ota file.... will give it a go.
