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]B&N authentication service!!

*2nd EDIT*
Okay now I don't feel so dumb, I renamed the otacerts.zip thing but i am still getting reset
I did find an application that is call BN authentication service. I can't uninstall it from the normal App installer, anyways to get around this? Like ADB
*EDIT*
Ha I feel so dumb, I just needed to reboot, then change the names. So after i changed the names I rebooted again and its all good now
Thanks eyecrispy

I have a rooted nook color with a stock 1.0.1 rom, CWR, and a over clocked kernal. I have only 1 real problem, I guess besides not being able to download from the marketplace - my nook keeps on getting reset by B&N! They don't unroot it, and my recovery is still intact, but it really sucks not being able to connect to their shop. It's not that I would use their shop it's just that I accidentaly press it every now and then and it resets my device. I have to back up my device once everyday to make sure nothing gets deleted because sometimes, even when I don't press the shop button, I don't even have to press anything, it resets the device after its been connected to wi-fi for a while. Like the other day, i just set it down to go to the restroom, I come back to find it at the Android setup or the quick setup selection page. When I select Android setup when I press the little android nothing happens. When I select the B&N quick setup it, i can do that no problem. So now I just turn it off from there and load my back up through CWR.
Anyways, is there anyway to stop it from connecting to the B&N authentication service or something? I have seen people with similar problems, but no one seems to have it happen to them over and over and over again.

Plenty of folks have reported this continuously happening. Have you disabled OTA updates?

Really? All th threads I have read people say it happened once but after a reboot it was fine. Maybe I just missed it. If you could please tell me how to disable OTA updates that would be a big help. Thanks

Found what you meant, I am trying to use Root Explorer but am having no luck. I gave it superuser permissions yet it still wont let me changes any system files

[Q] Refurbed NOOK Color dilemna

The LCD has gone haywire on my NC and I can't see any of the screens to reset it to stock.
I am running MIUI on it, and did the 8 consecutive reboots to get it to boot into recovery, but I can't see the options on the screens.
B&N has the replacement on the way, I just need to send this back per the agreement.
Any ideas on how I can get thing back to factory given that parts of the screen is unreadable?
What would you do?

Use ADB to make it unbootable, just start removing directories.
you can try something like this
Code:
adb shell
format SYSTEM:
format DATA:
format CACHE:

I had the same problem. I used android screencast to help me wipe my nook. It didn't work especially well but it will display the screen on your PC so that you can see what's going on. Unless it's been updated since I did it the screen will be turned 180 degrees and you won't be able to control it from the PC but it will work well enough to help you see what's going on.
http://code.google.com/p/androidscreencast/

Thanks guys...I've never used ADB, but I am downloading the SDK now. Its taking forever.
I think I may be able to figure it out between both of those suggestions.
The only other question I have is about my registration for the Market. I read one place where you should deregister your device before the new one comes in. How can I do that if I can't go into settings?

There's no way to deregister the device without doing it from the device itself. If you do the screencast option you can go through the steps to deregister the device which will in turn return it to factory condition and obviously remove it from your account on BN.

You don't deregister from the Android Market, although you probably want to deregister the Nook from your Barnes and Noble account and you can do that over the phone with B&N support.

I'm stuck.
I can't get Screencast to work because I can't check to see if it's in debug mode or detected by adb devices.
All I see is the boot recovery screen with a bunch of lines going through. The only option that is visible is "wipe cache partition".
If someone could tell me what other options are on this menu, so I can navigate up and down to reset this thing, that would be great.
Like, how many clicks down or up on each screen to completely wipe and reset to stock.
Or, if I just returned on RMA this thing, as is, would that prevent them from sending me a replacement (which I mistakenly though they did already)?
Who has screenshots of all the boot menus?

Bump - any thoughts?

[Q] TW Launcher Error

Okay, all!
I have been a lurker for a while now and y'all have been a BIG help (I am actually comfortable flashing ROMs- and I am learning the lingo - see?)
Now it’s my turn to post. I am helping a friend with her Samsung Captivate - AT&T. something happened last night (it had to have updated, because she doesn't really download anything. also - her battery started draining very quick last night. She had to turn it off for other reasons too.) And now get the "Sorry! The application TwLauncher (process com.sec.android.app.twlauncher) has stopped unexpectedly. Please try again. Force close" it is in loop mode, I cannot get anywhere after unlocking the screen. The status bar doesn't work, neither do the buttons. So I can’t even get to settings. I/we are not so worried about the phone itself, but she has some holiday pictures of her brother who recently passed away on it, and didn't have an SD card in it. So, this is really my last hope.
Now you are probably saying "well, why don't you look at other threads." I did! And came up with some options on my own as well. Below is a list of what I have thought of, have found, tried and have some questions on. Please let me know if you have any other options or info, as I am her last hope. The store and repair shops are not very helpful.
I can’t tell you for sure what she is running, but it should be current stock, no mods at all.
bat pull - DONE, no change
sim card pull - DONE, no change
force DL a new launcher from PC. - DONE, can’t get it to download. It says she never downloaded anything to the phone from the mobile market. (I think this may have something to do with not have 4g and Wi-Fi not on. from what I have read)
Built in recovery mode cache wipe - DONE, no change
I installed Samsung kies, tried to plug the phone into the computer, but the PC won’t recognize the phone. I think it is in charge only mode, but I can’t access the option to change it.
P.S. debugging mode is ON.
Okay, so now what I found on here - these lead to my questions as well.
If I "wipe user data" will this wipe pictures, videos, etc. as well? I do NOT care about apps.
I found the below threads and have questions.
http://forum.xda-developers.com/showthread.php?t=1795638
Post # 2 - can I do this from the recovery screen? And will is keep the data (pictures)? I don’t care about contacts, messages, etc.
Post # 3 - cans I re flash the ROM from the SD card? (Again - NOT rooted)
http://forum.xda-developers.com/showthread.php?t=1417244
Found and tried everything - it don' work Lucy.
I think this is all for the moment. I appreciate any and ALL help. She is to the point of tears about those pictures and I really want to bring her some good news.
edit: another try: press and hold search key for voice. - DONE. i get a connection error for voice. or an "app has stopped unexpectedly"

I would suggest doing wipe user data option. It shouldn't touch anything stored on your internal SD as you've already read elsewhere but there's always the possibility that things can go wrong. If you aren't worried about apps, text messages, and all that stuff I would also suggest looking at this http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3 If you go that route I suggest the Odin KK4 with bootloaders as your one click option. Going the one-click route will start you over with a completely stock phone as far as the ROM goes but again shouldn't touch the internal SD.

whoa, dude. a lot of questions at once.
what rom was the phone running before you started?
you say it got updated but at&t doesn't do ota updates on cappy. they direct you to use minikies update packs, not kies. from samsung direct to pc, not ota.

Have u tried to use ADB to get the pics, etc. off the phone and copied to the pc ?

not sure what rom she was on before - didn't look at the phone until today.
i think TW Launcher updated somehow. but i could be wrong. i was checking into the problem and found out about the Kies and tried that. but couldn't get the phone to connect. (i now can SOMETIMES get the notifications down.)

[Q] Kindle Fire 7", no home button, can't swipe, no settings displayed

I'm new to this forum and hoping I can get a bit of help.
I know NOTHING about what most of you guys do with rooting and changing out your systems and all that good stuff, however, I'm having a problem and your forum was the place that looked like the most likely able to help since I can't get amazon to get back to me .
My stock kindle fire had/has a problem with randomly turning off, especially in the middle of videos. A pain, but I lived with it. Then one day, this happened, and when I turned it back on, the home button, swipe from the top function, all settings, etc. had mysteriously vanished. Also, the keyboard displays what I believe are some Japanese characters. My apps all appear on the screen, but it won't connect to wi-fi and to get out of anything, I have to turn it off completely.
Like I said, this was just a stock kindle (not even sure which version...sorry!) and this just seems so random, but I'm *hoping* maybe somebody can help me get it to a functioning state again? Maybe if I could reboot it to factory settings? Not sure what would fix it, but any help would be appreciated. Please keep in mind that I am just a casual kindle user with no experience with tinkering with systems, and really just want it back to plain old annoying amazon stock. Don't have your lingo down either, so please, if possible, use words I'll understand. I mean, I'm able to follow instructions, etc., but not knowing all the terms can kind of stop me in my tracks.
Anyhow, thanks for anyone willing to help.
Cheers!
