I've heard about how it's pretty much impossible to brick the nook... Mine seems about as useful as a brick though. I was trying to set up a dual boot following these instructions. Basically, I had HC installed to the internal memory. backed it up, formatted system and data, then flashed update-nc-stock-1.2. CWM said that was successful. Then I rebooted with my CWM SD card out. Screen said "read forever" or whatever, then went blank. I waited for about 5 minutes, and pressed the power button. The screen went from an 'on' blank to an 'off' blank. Since then, I haven't been able to get it to turn on at all. Just an 'off' blank screen with no signs of life, even with charger cable connected. Tried it with CWM SD in and out. None of the buttons seem to do anything...
Thanks in advance!!
I'm pretty new to the Nook having just got it today, but I did some reading prior to attempting anything to see how easily I could back out if I had to.
Have you tried basically starting over (ie. Let go of the multi-boot dream for a bit and get back to basics)
You know, take a SD card, use diskimager to put the clockwork 3.0.2.8 image on it with the CM7 full ROM and boot to that, then format system, data and cache with clockwork and finally install the CM7 zip image (and gapps I guess) just to get going again.
If it all works, maybe take another run at whatever you are trying to do with the multi-boot stuff.
Thanks for the reply.
Sounds awesome; problem is I can't get the thing to do ANYTHING. boot period, into recovery or otherwise. I plug it in and it displays nothing - no 'wait 15 minutes and try again'. Just a black screen no matter what I do. I have an SD card with recovery on it, and i've tried making it do something with or without the SD card. No luck.
Good luck with your nook; I had really been enjoying mine.
So holding the power button for 10-15 seconds doesn't do anything?
Or when you plug in the power does it try to boot?
I mean in a complete worst case scenario you could grab yourself a T5 and open it up, disconnect the battery, and then reconnect it.
Then something is wrong with your Recovery SD card, as no matter what, hardware dictates that it reads the sd card first. The problem with what you did through dual boot methods is you resized partitions. So even if you do back out of all of this, you're going to be losing space unless you setup dual boot.
Recreate the CWM recovery card, either redownload the image and reburn it. Find a different one or something else, because it should load on startup.
Thanks for the help!
Reformatted SD again, then tried powering up with the power cord unplugged. Apparently it won't boot into recovery as long as the power cable is in, and whatever the boot was on EMMC was messed up. Happily running stock 1.2 now, next step, dual boot with HC!
Anyone know how I can delete this thread as it's pretty unnecessary?
I guess I bricked my iconia...
I installed Recovery, etc. But when I rebooted my device it starts up, and shows my initial display screen. But it locks on the display (it is past the Android, and Acer screen).
So I tried to recover the device using the unbrick procedures described in this forum, and others. But it seems whenever it tries to process any update.zip file including the unbrick the little android man either stops turning or displays a sign indicating things did not work out as they should have.
I have clockwordmod backup from my system. How do I use that backup? When I use my phone the device automatically boots into xrecovery and allows me to restore. How do I get that with the Iconia?
first of all your device is not bricked as long as you can boot into any type of recovery.
second you obviously have cwm installed, but anyhow even if you don't have it i hope you have an external sd-card.
dl any of the stock rom's from the dev section, basically best is to choose the rom made for your country.
extract the update.zip and put it on your external sd-card.
then install it with cwm if you still have it, or with acer recovery (volume - and power simultaneously until the recovery text shows up).
and then take it from there.
also good idea is to clean dalvik cache and data cache before restarting if you use cwm.
then you can reinstall root and cwm.

Thanks... The problem is I can't boot into anything.
How do I boot into cwm? I can't boot into the operating system as once it hits the display screen with my picture the system freezes and tries to power down?
I have been playing around with acer recovery, but all of the updates I downloaded will not load onto the system. It tries to install, gets about 1/3 through and then gives me an error.
Hence why I was thinking that maybe my backup has something?
push volume - (left volume button) first and power and keep your fingers on it until it displays the recovery text message on top left of the screen
If you are getting into recovery. And flashing. A rom give you errors or does not complete. This issue is a bad d/load.or a bad currupt SD card.I would say format your SD card again.redownload the correct rom again.don't use a download manager.then decrypt. Unzip then put the update.zip on your SD card turn off your tab install SD card.
Reboot
Holding down volume up and power until you see the 4th line of txt. It should take you to cwr. Or flash your device
good luck
Yep.. use vol-down and power to boot into cwm. Keep holding vol-down until you see tiny white text in upper left corner.
Then do full restore. When it's done, if you don't see "Backup Succesfull!" message, you'll need to restore flexrom from the advanced restore menu. This is because it failed trying to restore .android_secure.img and caused cwm to restart before flextrom was restored.
Alternatively, you can delete the .android_secure.img file from your backup set before doing the full restore.
Good luck.

Thanks guys for all of your feedback.
However, when I hold down the buttons you mentioned I do get those text items you mention. The problem is that unlike my android phone it does not pop up the recovery menu. It goes straight into the Acer Recovery procedure (The android with turning gears).
Could it have been that upgrading to a specific ROM the recovery procedure is shortcircuited????
What I am trying to figure out is how to get the recovery menu.
Same deal!
I have the exact same issue. The Update.zip will not take and the Android Gears screen gets to 1/3 before the yellow triangle. Any further help would yield loud THANKS!
your update.zip should preferably be those 3.1 full. cos I believe it does not check anything for it to fail.
Thanks Kenny that does help and explain a few things.
ok...so i was playing with the custom partition tool and ended up screwing up my phone...now the phone doesn't boot...i can't mount data or format it...can't wipe Dalvik's cache...i've tryed fixing this with a stock firmware...it didn't even want to install it...it's like the whole data partition off my phone is unaccesable...please helpp...
We do not know what you did to your phone, please explain it.
1) Did you use the tool that increases your internal storage for apps?
2) What happens if you hold vol+ and vol- and turn on the phone?
3) What happens if you hold vol+ while turning on the phone?
4) What happens if you try to simply boot up the thing?
5) What happens if you follow the instructions Huawei provides for updating the ROM?
You might have damaged the partition table of your internal memory. That should not be that big of a deal - as long as your computer still recognizes the device.
If your computer does not recognize the device, do the following: Download the .iso-image provided here. Burn it onto a CD and start it up, it is a linux-live-cd. There will be only one program, gparted. It will recognize your device.
No my computer recognises the phone...i tried to increase the internal memory...if i hold vol+ and - the phone goes in to bootloader...i cna also access the recovery mod...if i boot the phone...it just says IDEOS and frezzes there..i followed the instructions on huawei and stock rooms...install but at the end they say instalation failed...hope i didn't forget anything

Than all you have to do is go into Recovery, mount the SD Card, copy the customer Rom and install it.
Amm...well i tryed that...and it's the same thing..still get that same IDEOS screen and nothing happens..and what is a customer ROM?
We'll...it's over..my phone died:/...i tryed the gparted...and screwed something up even more...so i'm gonna take it back tommorow..tnx for the help..
If you do not explain what you doing exactly I am afraid I cannot help you. gparted is a tool used to format and partition memory. You cannot screw up anything, it is just a software change. I suggest you tell us what you see when you select the device within gparted (which partitions show up etc.) before returning it.
i see nothing..the phone doesn't even wanna turn on now since i did something with gparted...and gparted doesn't show my device..cos it doesn't read it...it's dead..
If it does not turn on anymore you do need to send it in for repair. Please be careful the next time and if you do want to apply that partition program, do exactly what the instructions say. Besides overclocking this is the only thing you should not experiment with.
Well hopefully you get a new device (or a repaired one) soon!
If anyone can help I would appreciate it.
I followed this post about installing cyanogenmod 7 onto an SD card to boot my nook color off of the SD card.
http://forum.xda-developers.com/showthread.php?t=1000957
Everything worked great and it has been up and running for several days, very happy with the results.
Now I was trying to put gapps on the SD card and I followed the instructions shown below:
How to install market and gapps:
After you have booted into the CM7 on SD card for the first time and set up wifi access (important!)
Go to http://wiki.cyanogenmod.com/index.ph...Latest_Version and at the end there is a table with various google apps versions. Get the one suitable for your cyanogen version (CM7 is the latest for now). The file is named gapps-....zip
shutdown your nook and take the SD card out, insert it into your computer.
Copy the gapps-... file to the SD card on the first partition (titled boot) without changing the file name.
Insert the uSD card back into the NOOK and boot into "Recovery mode." To boot into recovery mode: Boot normally into Android, then from desktop hold power key until a poweroff menu appears, In the poweroff menu choose "reboot", in the next menu choose "recovery" and press "OK". The nook would reboot straight into recovery.
So i have tried this several times and DL the file twice just to be sure but every time I reboot the system just comes up normally. I wonder if the gapps install package is named wrong? I don't know how to make this work.
Any suggestions?
Thank A LOT for your help!

turn on the NC, like normal, then power down, then you'll get option to reboot, reboot to recovery.
I'm sorry if my original post didn't make this clear, but I was trying to boot into recovery. I held down the power button until I got the shut down options and pressed restart then pressed recover mode. Every time I try this the nook just restarts in normal mode. I'm not sure if I've done something wrong or if this method doesn't work.
Just to give more information the file I used was:
gapps-gb-20110613-signed.zip
I didn't unzip the file I just copied it to the SD card BOOT partition.
Seems like you've done what eggnoodle suggested and if it didn't work, the only choice is using combination of N & power button. It needs some skills.
Try that, won't hurt.
I tried that several times, and it didn't work.
Is there a way to verify if I am in recovery mode? I'm not sure I am actually making it into recovery mode.
Further down in the instructions it says that to install other stuff anything with the name "update-***.zip" will install on recovery mode. So I will try renaming the gapps file to this and give it a try.
If you see the "Penguin" with scrolling text running horizontally on the NC screen, then it is in the Recovery mode.
If you see the Android guy or CM7 logo, you are in the normal booting mode.
Ok, so my problem is that I can never get the nook color in recovery mode. Perhaps the instructions on the forum are kinda flawed.
This is what I am doing:
Hold down Nook button.
Hold down power button
Loading screen appears then goes blank
Release power button for less than a second
Hold down power button again.
Wait for loading screen to appear
Release power button
Wait for screen to go blank
Release the Nook button
Then the NC just boots up like normal. Is this the correct process?
The NC boots up normal if I choose restart in recover mode from the shutdown menu also.
Any suggestions?
As I said, you need some skills.
Don't panic!
After a few tries and when you get it in, you will mumble "hmm, it's nothing like the instructions, it's much simply than that, wheewwww"

Did you try going into recovery while in CM7 by powering it off and selecting reboot>reboot to recovery?
I did try that, just boots up in normal mode.
I cannot get this thing to work, I have also tried several different ways to boot up using the home button and power button I can find a combination that works.
so frustrating!
Maybe start over fresh with Cm7 and gapps install?
I intall CM7 and gapps at the same time...
Just to be clear I didn't try this because the instructions said do not do it.
Ok, so I reinstalled with gapps and cyanogenmod zip files both on the boot SD before it was installed and it took, but there were a few hang ups like it kept bringing in stuff from my phone when I linked to my google account. So I think I should be good.
Thanks for the suggestions.
That happen to me too. It installed a wallpaper that was on my phone that I no longer use. Strange? But as long as it worked, that what I cared about!
Yup same thing to me, it installed the wallpaper and some other apps.
Why won't it install angry birds, the market says it's not compatible? What the heck's up with that?

The new market has issues with nook color. Market is looking for a 160 density level when the nook color is set to 161 to avoid panics.
Ive been using LCDDensity from the market and choosing Density 160 and changing the drop down to killall and click apply (reboot)
after it reboots go into manage applications and do a force stop on the market and clear the data/cache
it will reload and you will see all the options until the market resets itself. very annoying i know but its a temp fix until someone figures out how to fix this
Forget that stupid method with the buttons, it's a waste of time.
I tried it both ways and it doesn't work.
Use this instead, works like a charm.

I have the same problem as Steveolio and followed exactly the same procedures. Maybe these error messages from recovery boot help some experts with a good idea:

Does that possibly mean gapps file is not in the right location?

There is no "Thanks" option so I just wanted to say Thank you! The button combo for booting into recovery has been kicking my butt and this was simple and worked flawlessly!
First of all, lets get something straight. Most people use the term "bricked" improperly. A bricked phone means one thing: your phone won't turn on in any way, shape or form, and there's nothing you can do to fix it. It is, for all intents and purposes, as useful as a brick. A phone stuck in a boot loop is not bricked, nor is a phone that boots straight into recovery mode. These are things you can usually fix, and they're a lot more common than a truly bricked phone. If your phone is*actually*bricked, you won't be able to fix it yourself (but there are things you can do—see the end of this article). For those other problems, you have a few options.
If Your Phone Keeps Rebooting: Wipe Your Data and Cache

If you've flashed a ROM and your phone won't boot into the home screen, it's probably because you forgot to wipe your data and/or cache. It's trying to boot into the ROM, but some leftover data from your last ROM is causing it to error out, and it'll reboot itself over and over again. If your phone's eating a big bowl of boot loops, your first course of action should be to wipe its data and cache, which you can do from recovery mode. This method assumes you're using ClockworkMod Recovery, like the majority of Android users, but if your particular phone uses a different third-party recovery (like AmonRA), you should still be able to find these options in the interface. They might just be in a different place. To wipe your data and cache:
Power down your phone. Turn it back on and boot into Recovery mode. This is a bit different for every phone, so you'll have to Google how to do it for your specific model. Usually it involves holding down another button, like Volume Down, as you turn your phone on. HTC phones will have to then select "Recovery" from a menu, while other phones will boot directly into ClockworkMod. You'll know you're in ClockworkMod by the words "ClockworkMod Recovery" at the top of the screen.Use your volume keys to navigate the menus, and your power button to select menu items. Scroll down to Advanced, and choose "Wipe Dalvik Cache". When that's finished, go back to the main screen and choose "Wipe Cache Partition". Lastly, head to "Wipe Data/Factory Reset". This will delete all your settings and apps, but you should still be using the correct ROM.Reboot your phone.
With any luck, it should boot right into your ROM. If that didn't work, try the below method with the same ROM (or with a different ROM) and see if you get different results.
If Your Phone Boots Straight Into Recovery: Flash a New ROM

If, when you boot up your phone, it goes straight into ClockworkMod, then there's likely an issue with the ROM you flashed. Note that some ROMs boot into recovery mode automatically after flashing, so reboot your phone once from recovery mode to make sure you're having a problem. HTC users: if you boot up your phone, it might go straight into the bootloader—check to see whether you can choose "Recovery" from the list before continuing to the next step. HTC phones usually don't boot straight into recovery.
In this case, you'll want to reflash the ROM from scratch. Try again with the ROM that messed up your phone, if you so choose, but if that doesn't work, try an entirely different ROM. The best way to do this is to download a ROM from somewhere on the net and putting it on your*SD card. You'll need to take the SD card out of your phone, and you'll need an SD card reader that you can plug into your computer. Here's how it works:
Plug the SD card into your computer. Drag the ROM's ZIP file to your SD card, and wait for it to copy.When it's done copying, eject the SD card and put it back in your phone. Reboot into Recovery mode. This is a bit different for every phone, so you'll have to Google how to do it for your specific model. Usually it involves holding down another button, like Volume Down, as you turn your phone on. HTC phones will have to then select "Recovery" from a menu, while other phones will boot directly into ClockworkMod. You'll know you're in ClockworkMod by the words "ClockworkMod Recovery" at the top of the screen.Use your volume keys to navigate the menus, and your power button to select menu items. Scroll down to "Install ZIP From SD Card" and navigate to the ZIP file you just copied over. Give it time to flash the ROM.When it's done, reboot your phone.
Hopefully, your phone should successfully boot into the new ROM. From there, you can probably assume that the previous ROM that messed up your phone isn't going to work, and you'll have to find another ROM for now—or find another copy of that ROM that isn't corrupted. Remember to make backups of your working ROMs so you don't lose all your data!
If Your Phone Boots Straight Into its Bootloader: Restore From a Stock ROM
If you're really having trouble, one of the most surefire ways to get your phone working again is to restore from the original ROM your phone came with—unrooted, stock, stable goodness. Each manufacturer and phone has a different method for doing this, and we can't go into too much detail here, but we can steer you in the right direction.
Note that this will unroot your phone, and return it to exactly how it was when you bought it from the store. You'll lose all your apps, settings, ClockworkMod recovery, you'll get over-the-air updates again, and you'll even have to re-activate your phone if you're on a CDMA provider like Verizon or Sprint.
This is less likely, but it's a problem I and a few others have run into on occasion: sometimes your SD card just gets corrupted, which makes the above methods useless (since they rely on your SD card to work). Take your SD card out of your phone, put it into your computer using an SD card reader, and format it. It's very important that you format it through an SD card reader directly and not by plugging in your phone in USB mode—I learned this the hard way. Format it as FAT32 and try the above methods again.
Other errors, like during the ROM flashing process, might give you a hint as to what's wrong. Try heading to the*XDA Developers forums*and asking for help, as your phone could have one of a million specific problems we can't address here today. Remember, if your phone turns on, there's still a good chance you can recover from whatever error you're experiencing, so don't give up just yet!
If Your Phone Is Truly Bricked: Take It Into the Store and Play Dumb
If your phone is actually bricked—that is, it won't turn on at all, no matter how hard you try—it's time to give up and move on. The first thing you can do in this situation is try to take it back to your carrier's store and play dumb—just say something like "I don't know what happened, but my phone won't turn on anymore" (don't tell them you rooted it, obviously). Most carriers don't have time to deal with such issues and they'll just give you a new phone. Sure, it's a tad evil, but it should work most of the time.
If they're wise to your act, though, you can try another store or just sell your bricked phone for a few bucks on Craigslist. Sadly, if no one will replace your phone, you'll have to buy an entirely new one. Such are the dangers of rooting, but don't be discouraged! Bricking your phone is pretty rare, so I wouldn't worry about it being a common occurrence. As always, though, when you void your warranty, only do so if you're ready to replace that device completely, since you never know what can happen.
Sincerely,
