Unrooting Nook Color - Nook Color General

Is it still possible to unroot a nook color once clockworkmod recovery has been installed?
Thanks,

Yes. You would just need to put Clockwork on an SD and use it to flash a stock image back to the Nook. I know there are threads here at XDA, don't have a link off-hand, but here's the first result on Google when I search NOOK COLOR STOCK IMAGE.
http://theunlockr.com/2011/02/14/how-to-restore-the-nook-color-to-stock/

Thanks a bunch for the reply. Will search it out some more. I was confused as I heard someplace that if you could not if cwr was installed.
Again thanks.
Best,

The Ultimate Noob Guide-Need Help Please

Hi guys,
I recently bought a Nook Color and i want to root it. I am hearing things about Autonooter and putting an image on my micro SD card. Personally i just want the best option to root my Nook, i want to overclock it aswell .
Really sorry if someone has already posted a thread like this, i tried searching for one.
I havent opened my Nook Color yet so guessing the software would be 1.0.0 so how would i root it to 1.1.1 and also stop OTA and install a overclocking software.
Thanks, XDA is amazing, recently rooted my Notion Ink Adam
I too would be interested in such a thing. There is information all over the place, but most seems to be geared toward people that understand the "lingo" and such...
I agree
reading MD5 hash
I'm pretty new to this- I have my NK running 1.0.1 using autonooter and want to update to 1.1. I think I've got a grip on using ClockworkMod, but in the instructions for downloading the 1.1 kernel, it says to "check the MD5 hash"- how do I get this info from the downloaded ZIP file? I don't want to even try and do the update without making sure the download is not corrupt.
Thanks!

I have to say though, to the OP, that reading through all the guides (and some comments) in the dev forums would be the best because you'll learn all the ins n outs. Having a noob guide is fine but it's fun searching for the info yourself and you'll learn/remember a lot more about your device. having a noob guide that is not comprehensive enough just promotes needless questions when the info is all over the place elsewhere.
Thanks for the link superkevx! Additionally, is there any way to do the check on the Nook itself? I downloaded it using the stock browser & can pull the SD card and check it on my 'puter, but it would be nice to be able to just do it locally.
I agree with you comment about the noob guide- I've learned so much trolling the dev forums...
i do try to find everything its just some things i dont get:
like clockworkmod, i think its to do with disabling OTA but im not sure
which is better,autonooter or installing on SD
,if you could answer these questions i would be really grateful thanks

Patrikc8- from my experience (have ROM Manager & Clockworkmod installed in prep for 1.1 update), Clockwork mod is used for making system backups and doing system restores (including installs of custom ROM's)
As far as the SD vs autonooter- installing to the SD means that you typically don't touch the original system files on the Nook itself- good for trying out a ROM that you are interested in but not sure you want to keep. There may be a performance hit though because you're constantly reading from the potentially slower SD media (correct me if I'm wrong on that anybody). I used autonooter to root my Nook and it has worked great since- it is apparently a very easy way to root and I had no trouble doing it.
Aha!

For what it's worth- did a little investigating & you can use Astro file manager to get the MD5sum- just do a long touch to the file in question and choose "Details".
SHould i use auto nooter 1.0.1 or the nook color v1.1.1 ROM?
and im guessing you have to root it first then install a rom then install a kernal?
would there be a big difference in 1.1.1 and 1.0.1 ?
I bought my Nook Color a couple of weeks ago. It was on 1.0.0. The first thing I did was update to 1.0.1. I then downloaded the Autonooter for 1.0.1 on my pc. I also installed Win32DiskImage.exe on my pc, and followed the directions to burn the image to my sd card. I followed the instructions exactly as they are laid out on nookdevs. I then reformatted my sd card back to normal to use for storage in my device.
One thing that happens when you run autonooter is that clockwork recovery is installed. This is simply a tool that will allow you to perform functions at a lower level than the android interface will allow. It my look a little intimidating at first, but go slow, and make sure you are absolutely sure that anything you do in CWR matches what it is listed in the instructions posted. Every action requires a confirmation, so, again, go slow and think it through.
A few days later, the 1.1.1 update came out. I used the updated Rom and instructions here:
http://forum.xda-developers.com/showthread.php?t=932145
Something that I found confusing is using alternate home screens. I finally determined that Zeam was the right choice for me. It is free in the market. The other tool you should download from the market is called Home Switcher. It will let you switch between different launchers (e.g. Zeam, BN stock home, etc.). Again, you will probably have to experiment a bit to get things working the way you like.
Lastly, to improve the performance overall, I flashed a few different kernels. You may want to play with your nook for a while to get comfortable first. When you choose to flash a kernel, you will boot into recovery (this brings up the Clockwork Recovery program), and pick the zip file that you download to your sd card. My recommendation is to start with the 900mHz kernel first. Make sure your nc is stable, then try some of the faster ones.
As far as MD5s, I have not ever checked after downloading, and have not had any problems as a result. It is something I need to investigate further and start doing.
Hope this helps. I do agree with superkevx above. Browse and search and experiment. It is very unlikely that you will do any permanent damage to your nook, although it is possible. Everyone needs to have at least one bricked device along the way. I have learned more by rendering my devices inoperable and then figuring out how to get them back again. You know you're doing it right if your palms are a little sweaty as you wait for your device to reboot.
you guys have been great , thank you

Best option for NC 1.4.3 unrooted

I apologize in advance if this has been asked before, but I searched and couldn't find anything.
I never rooted my Nook Color (firmware 1.4.3) because I like the simplicity of it and I only really wanted to read books on it.
However now I wanted to install other readers so that I could read other formats without having to convert to epub or pdf.
I tried downgrading to 1.2.0 but it still doesn't let me install other apps.
What would be my best option?
Is there any way to do this without rooting?
I'm not afraid of tweaking, I just prefer the stock firmware to use as an ebook reader.
Best regards,
Rita
Best Option According to me
Rita,
Sincerely the best option for you right now is to run CyanogenMod 7 off an SD Card, a port of Android 2.3 for your device. I have a Nook Color too. I used to love stock but the lack of functionality made me install CM7. There are many easy to follow guides available on the internet. If you would like I can tell you how to install CM7 on an SD Card. That way you can enjoy both stock and CM7. Cheers!

You can do what the prior user recommended (CM7 on SD) and also go back to the latest stock software on internal memory and root it. Then you can decide which you want to use. If you look in my tips thread linked in my signature you will see how to flash the lastest unrooted stock software with CWM recovery. Look at my item A12. Then you can root it with Manual Nooter 5.08.20. You can add other apps with unrooted stock but only from the B&N app store. If you want more apps than that, you must root.
@satya-1998: I've already tried installing CM7 on a sd card and I liked it, just not for reading. As an ebook reader I really enjoy the simplicity of the stock firmware.
@leapinlar: I've already put the latest firmware on the nook (1.4.3) and I think rooting will be my best option. Will rooting and using manual nooter 5.8.20 keep the B&N functions and allow me to install other apps?
Do you think following this thread (http://forum.xda-developers.com/showthread.php?t=1494901) would be the way to go?
Thank you both for your help, Rita

Ok, now that you have rooted your nook, you can keep it at stock and also keep CM7 on the SD card. If you like the B&N reading, download the Nook app for android onto cm7. Cheers...

Use this simplified guide.

You can try a dual boot from
http://forum.xda-developers.com/showthread.php?t=959461&page=1
But I recommend going with booting off an SD card. Much easier, and although it can be a PITA swapping SD cards, you dont run the risk of losing partition space, or having a problem if you have to go to BN for whatever reason.

v1.3 to 4-6-16

I installed manualnooter-4-5-18 with no problem. But when I install manualnooter-4-6-16 device gets stuck on colorful Nook Color logo show.
My version is 1.3.
I also need some advice:
1. Isn't it better to use cm-7.2.0-encore instead of original OS? I can't decide.
2. Shouldn't I update to more recent versions of nook software (higher than 1.3) then mod it?
Thank you for software and support

It depends on what you want.
If you are invested in the nook store with lots of purchased apps or want to read interactive kids books, stay with stock. If you stay with stock, upgrade to 1.4.3 (you can get a CWM flashable version by looking in my tips thread linked in my signature) and root with Manual Nooter. I think it is up to 5.08.20.
If you are not invested in stock, definitely go to CM7.2. It is smooth and very stable.

So I decided to go with CM7.2 but
http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Full_Update_Guide
says it only works with 1.2. I got the link to wiki from here.
And one technical question, does CM7.2 remove original Nook Color OS completely? If so why its version matters?

Yes, if you install CMx on EMMC it will replace B&N ROM on the device.
That is an old instruction... The reason that method only works with 1.2 is because they have you rooting it and installing CWM on EMMC. By making a bootable SD and installing CMx from there, there is no reason to root the B&N ROM before installation... so you can install it regardless of ROM on you NookColor.

So I just copy the CM into the flash (that I had made it bootable with CWM) and install CM from there. I create a backup using CWM.

[Q] restored to stock, but cyanoboot still there

I installed CM10.1 on my 2-week old nook HD+, following these (excellent) instructions.
Actually before that I was having charging problems - the charging light went green occasionally when the nook was plugged in, even when the battery was low, and so it thought it was charged and stopped charging.
Anyway, this charging problem got worse and worse, so I restored to the backup of my stock rom, confirmed the problem, discussed it with nook support and they said return it.
My problem:
The nook appears to be back to how it was in all but one respect: if (within the stock OS) I "erase and deregister" to do a factory reset, in the reboot sequence it comes up with cyanoboot and says something like "this is not rooted, do you want to root it?", if I click no it continues, and looks like a normal stock nook hd+.
My question: How can I remove this cyanoboot, so everything really is exactly how I bought it?
Thanks a million.

I literally just did the same thing. I was trying to install CM to SDCard, but must have gotten the wrong rom or boot image (I can't remember which decides where to actually install the ROM). Now I'm getting prompted to setup my CyanogenMod account.

For both of you, go to my HD/HD+ CWM thread linked in my signature and read items 5 and 6. A restore of a backed up stock will restore most of stock, but if you also put a custom recovery (CWM or TWRP) on internal memory, it will not restore the stock recovery.
The solution for both of you is to flash one of my plain stock ROMs from item 6. Be sure to factory reset with recovery too.
Edit: And for you sflesch, the Nook HD/HD+ is different than the Nook Color, it is the ROM zip itself that determines where the ROM gets installed. You must get a specially prepared ROM directly from an SD thread here for it to install on SD. Any ROMs you get directly from CM will install to internal memory no matter which CWM you use.

So the rooted ROM 2.1.1 will have cwm installed on the firmware of the device? I realize (at least I think) that's always been the case wen you root a device, but I always associated rooting a device with installing a CM flavor. I guess I was just thinking rooted stock means stock wit root access, not realizing you had to have cwm also.
p.s. I'll send another beer your way later this week.

No it does not have CWM. It has Cyanoboot as a second bootloader to help break the protection scheme. That is what you are seeing. If you want CWM on internal memory you must flash it separately.
And you are right, rooting is adding root access to an existing ROM, not installing CM. CM happens to be already made with root access, but installing CM is not rooting.

I should know better than to mix up my terminology and pay more attention. Yes, Cyanoboot I think is what I was seeing. So, in short, is there a way to get root access/install from unknown sources, etc. without actually having the Cyanoboot screen? My Nook is still under warranty and, although I generally trust you guys, I'm afraid I may mess something up myself and render it useless.

Yes, you can use the old root. And you don't need root for unknown sources.
Edit: You will need to flash the plain stock ROM to remove the second bootloader and root files first.

[Q] Nook HD+ Boot Issues

Hi Everybody,
I tried to look for situations similar to my own but couldn't seem to find any. I followed this guide: http://forum.xda-developers.com/showthread.php?t=2602796 to root my new 32 gig Nook HD + and everything was going fine up to step 9. When I tried to install the cm 11 zip, I was getting a status 7 error, and as an idiot I forgot to backup my Nook. So I completely understand that it is my fault, but I was wondering i there is any way to go back to stock rom, because all my Nook does is boot up to the CWM. Thank you guys for the help!
Flash correct CWM. CM 11 needs different recovery. Check verygreen's thread
Sent from my HTC Sensation using Tapatalk
I downloaded the version from the thread then installed it from the CWM menu. Is the version still 6.0.4.6? Because even after I install it I keep getting the status 7 error when I try to install cm11.

Two places to point you:
1. To install CM 11, you should make sure you are using the CWM version from this:
http://forum.xda-developers.com/showthread.php?t=2600572
2. To return to stock, you can find info and the stock images on this thread:

See I've tried using the CWM from the first link, but it doesn't seem to make a difference. I know this will make me sound like a noob, but when the instructions say that I need to "flash" the recovery image (and so on and so forth) it just means to install them through the ClockWork Mod menu correct? Because even after I flash the cwm recovery image, it doesn't make a difference. I still keep getting a status 7 error when I try to install CM 11. I'm also worried that because I put the cwm internally on my Nook (at least I assume I did from what I got from following the guide) I wont be able to change it.
Sorry I keep bugging you guys, I understand if I screwed myself over, but I'm still trying to figure out what I can do to fix my HD+ if possible.

Yes, when the instructions say to "flash" they do mean install via CWM, as described here:
http://forum.xda-developers.com/showthread.php?t=2317500
in the section of the original post titled "Back up stock ROM & Install CM 10.1 or CM10.2"
Typically you get a status 7 error for one of two reasons: 1) wrong version of CWM, 2) the ROM you are trying to flash/install isn't actually for your device (or, at least that's what CWM believes). This may be a silly question, but are you sure you have the right version of CM? You downloaded from here, http://download.cyanogenmod.org/?device=ovation I assume, and you're using one of the CM11 nightlies? If so, there's a small chance you've got a bad / corrupt download. I'd re-download CM11 and try again.
If that doesn't work, I would go to leapinlar's thread (the second one I mentioned in my prior post), scroll down to item 6, and follow that process to revert to stock (including stock recovery). At that point, you will be back to where you started -- stock ROM and stock recovery. Once you are back to stock, you can have another go at it. Since the CM11 install seems to be giving you trouble, you might try 10.1, following verygreen's instructions http://forum.xda-developers.com/showthread.php?t=2263553 there is also a link in that thread to a simplified list of instructions. FWIW, I'm on 10.1.3 stable and haven't found a compelling reason to move (although I probably will at some point). Another option would be try 10.2 following verygreen's instructions here: http://forum.xda-developers.com/showthread.php?t=2389813
