[Q] dual boot without removing sd? - Nook Color Q&A, Help & Troubleshooting

Hello. I've searched and googled and still can not find an answer. So I ask. Can you boot both CM7 and stock BN software without taking out the sd card? We bought our two oldest (11 and 10 yrs old) NCs for christmas and we don't really want them removing the cards just to use the stock NC. We don't want them to lose the cards. They both read a lot. But we want them to have the full android experience. I already have the latest build of CM7 on two 8gig class 2 Sandisks.

I am not an expert and haven't played with dual-boot option but AFAIK, by default, it will boot into the uSD FIRST. If you want it to boot in eMMC, you can (or must) press and hold the "N" button during the power up, then select boot Normal.
So, i.e. if you have CM7 on usD and Stock in eMMC, by default, w/o interacting, CM7 will be booted.
If you want to boot the Stock, you have to press the N button then select it.

To clarify this correct answer, when you see the screen flash when booting, hold down the "n" key. You'll see the CM banner and under it there will be something like "boot menu" display. You can quit pressing "n" at this point. It will then continue to a boot menu display (all the directions are on that page). Press the "n" key to select "emmc", then press the down volume key to select the next item ( it should be "normal" so just leave it there). Push the down volume key again, press "n" and it will boot into the stock ROM. The next time you boot, it will still boot to the SD card unless you repeat the process.

Thank you both for the quick reply. It was very helpful.

[Q] What am I doing wrong?

Using the verygreen instructions I have been running CM-7.0.3 encore signed off of SD for about 2 months now and want to try to update to the current nightly.
I put cm_encore_full-176.zip in the /boot directory of the SD and tried all of these without success:
1) Used the boot select u-boot.bin to boot from sd and recovery. It just hangs.
2) Used the boot select u-boot.bin to boot from sd and alternate. It just hangs.
I reverted to the standard u-boot.bin and did these without success:
1) Booted into CM7 then using the shut down menu rebooted into recovery. The update was not applied and boot was normal.
2) From power off, held down the power on and N buttons. After loading... appeared counted to 4 and released both buttons. No update applied and booted normall.
3) From power off, held down power on and N buttons. After loading... appeared, released power button, then pressed and held it for 5 seconds, waited for the screen to blank and let go of both buttons. No update applied and NC shut off.
Anyone know what I am doing wrong? I have been scouring all of the NC root sites and it seems everyone has a different hold buttons and release sequence. Is there a special /boot folder or something that can only be accessed while the sd card is in the NC where I have to copy the update zip file?

Why you doing that?
Because there were recommendations to do to those steps on this site and others.
Do you have a solution to my problem?
You are going from a .29 kernel to a .32 kernel... From VG's SASD thread... first post... you need to update the version of the SASD.
How to update if you already installed using older version of the installer and don't want to reinstall (understandably):
•Get update zip from http://crimea.edu/~green/nook/update-genimage-1.3.zip
•Put the zip file as is onto the first partition of your sdcard..
•reboot into recovery (triggered by the keys, the reboot into recovery does not work yet).
•The new version would be installed and you are done.
•You can combine this installation together with updating to .32 kernel in one step. Just put the update-cm file and the update-genimage-1.3.zip to the first partition. Make sure there is still at least 1M of space left!

Just put the new nightly build into the root folder and boot into recovery.
The only thing you need to do is your skill to boot into recovery, that's all.
The rest should be taken off.

Ok copied the file onto /boot.
Tried a different button sequence:
http://www.youtube.com/watch?v=Kps9cWvyzqo
It still will not go into recovery mode. The thing is that I used the instructions on the video to help me install CM7 and gapps in the first place and it worked fine.
What exactly is the correct button sequence to get the NC to power on to recovery mode?
As you can see I found 3 different people saying to do it 3 different ways and none of them seem to work.
I am waiting for someone to say you have to wait until the 4th tuesday of the odd numbered month and hold down the buttons to the count of pi * the number of times Lindsay Lohan violates her probation in the past 4.5 months.
Do I need another program installed for this to work? Something like clockwork recovery mod (whatever that is)? Is there a difference that my NC doesn't say "Touch the Future of Reading" but just says "Loading..."?
It is making me pull my hair out and I didn't have that much hair left to begin with!
Just wanted to add an observation that after doing the button sequence in the video, "Loading.." the screen blanks for about .5 second and then is displayed again off center. The it goes into normal boot up.

I've had to use the "rhythm method" for the first time in a while this week, setting up my dual boot on eMMC, and verygreen's instructions were the only thing that worked for me:
verygreen said:
hold nook N key and then press and hold power until the "Loading..." message appears and then disappears with screen going blank. Release power button, then press it again and hold for ~5 seconds, the bootloader "Loading..." message should be on the screen for three seconds or so before you release power button, keep holding N button until screen blanks again. If the screen went off while you were holding the power key, that means you were holding it for too long

is what should be happening--when the message comes back, press the power button again for five seconds, then release. Anamardoll's videos were made prior to the B&N 1.2 update, prior to CM7.1's existence, and prior to any of verygreen's SASD updates, so the behavior was a little different then.
Also, you may have successfully booted into recovery and installed the SASD 1.3 update file without realizing it--small packages can flash very quickly in verygreen's installer, and iirc, the "Loading" message you describe is expected behavior for SASD 1.3. If you look at the SD's boot partition in your PC and the .zip file is gone, it very likely installed. If that's the case, Power > Reboot > Recovery ought to be working now; copy over the CM7 update .zip, attempt the rhythm method again (may as well), and if you go straight through to CM7, try Power > Reboot > Recovery.
If none of the above works, you have very likely hosed your boot sector with some of the shenanigans in your OP, and may as well format the card and start from scratch with an up-to-date SASD image.

CWM cannot help you with an SD install. If, however, you have chosen at any point to "Flash ClockworkMod Recovery" from ROM Manager, then you've already written CWM to your internal recovery partition, and might want to consider installing CM7 internally, as it would now be much easier than fixing your card (assuming none of the above got it done).
Thanks for the help all.
I am just going to redo the sd with the 177 nightly.

[Q]

Alright everyone, I have an NC that I rooted quite awhile ago to great success. However, in my quest for updating to ics, I completely deleted everything. Buttons don't work, and for some reason I can't have it access my computer's hard drive because it won't turn on.
So, if anyone has any ideas for fixing it, it would be much appreciated. All I think I need is the original NC software (everything) and a way to put it on the hdd that I can't access. Thanks in advance.
I think you should be able to make (or re-use) a CWM card and use it to install a fresh rom. Unless it's totally borked, the NC should still boot first from the SD card.
I would, but the only problem is that I cannot even get the device to power on, the buttons don't work.
Edit: Here's the deal, I just need the damned thing to power up for me so I can mount the sdcard and restore it. But whatever utility makes the buttons work, is gone - they aren't just merely broken. So I can press the buttons and the kernel or whatever it is that interacts with the buttons will not understand what is going on because the utility is not there.
If anyone has a solution for either powering it on via usb (with the device off) or getting the buttons to work again, great.
Can anybody access their NC cwm for me and try to find whatever it is that I deleted? It has something to do with buttons or what not.
Are you holding the power button on for several seconds.. Until the screen flashes?

^ What he said. Sometimes I have to hold the power down for quite a while, or try it several times. This is usually after an SOD (it may help to have it charging too).
Yes and yes. I hold it for quite awhile. Still does nothing.
Have you tried holding down the n button along with the power button?
Hold both for 10 seconds. Release. Hold power button alone for 10 seconds. Sometimes it takes 2 or three cycles of holding down both buttons, then the power.button to get the nook reset.

Just because the screen does not flicker, and you can’t access the file system from your computer using a USB cable, does not mean that the device has not powered on. I can format the whole file system, and the power button will turn it on every time. For turning on the device, the power button is independent of the file system.
It sounds like you have just screwed up the files in the boot partition. I screwed up my device to this point more than a couple times. I had the same none flickering screen, and no file system access from a USB cable. The NC is programmed to boot from a SD card before internal storage, there is really no way that you could have screwed it up to the point that it won’t continue to do that. Below are the steps that I have always taken to get back to a working device,
*fully charge the device, this is very important, because the device might have been on this whole time, and you just could not see it
*Download the stock 1.2 update.zip found HERE, get the “update-nc-stock-1.2-signed.zip” file
*Now download the file to make a bootable CWM card found HERE
*Follow the directions in that post to make your bootable CWM card, then place the “update-nc-stock-1.2-signed.zip” file onto that card
*Put the bootable CWM card into your NC
*Hold the power button, and count to 3, then let go
*If after a count to 10, nothing has appeared on the screen, repeat the last step, you most likely just turn the device off.
*This time CWM should load up, select “wipe cache partition,” followed by “wipe cache partition”
*Now scroll down to and select “mounts and storage”
*Now scroll down to and select “format /boot”
*When that has completed, you will then select “install zip from sdcard”
*Then select “choose zip from sdcard,” and select the “update-nc-stock-1.2-signed.zip” file
*If you receive an error at the very start of the install process, you need to select “toggle script asserts,” to disable script asserts
*When that has completed, remove the card, select reboot the device, and boot the device no SD card in it
Your device should now boot just like stock. At this point you should be back to a completely stock NC.
Report back with any results, good or bad.
Is it necessary to format /system and /data as well if changing between firmware?
Can't try it just yet, but after I'm done traveling it will be top-priority.

how to boot into CWR

hi, i have trouble booting into recovery. what i do is press "n" and power and it always goes to "Boot Menu" ... can someone tell me what that is and what it does ? ( i know i can boot into it by pressing power and selecting reboot and recovery just trying to find out how to from power-off) thanks.
I'm not the most knowledgeable one to answer this. I was waiting to see if someone else would post here.
But here goes. When I want boot into recovery when my nook is off, I power on holding down the n key. When the boot screen appears, I use the n key to toggle different options on the first line. I opt to boot from emmc. Then use the volume keys to move down to the next line and use the n key again to choose boot into recovery.
I don't remember the exact order of the lines, so I may be a little off, but I hope this helps get you booted into recovery from the boot screen

Thanks for trying to help. i was experiencing boot-loop i think.. ( i wasn't even able to turn my NC off at all. it just kept booting up and being stuck on the Cyanogenmod loading screen every time when i turn it off by holding down power), thats why i needed to boot into recovery from power-off. how it happened was i upgraded to cm9. i wiped cache and dalvik and formatted boot, system and data before flashing. ( i know some instruction here tells to do a wipe data/factory reset. i didnt do that ) I fix it and went back to cm7 by putting in a bootable sd with CWR in the two seconds that it stays off... but the strange thing was that once again i did it my way (wipe cache/dalvik and format boot, system, data) and this time it worked~ no boot-loop. now i wonder what really caused boot-loop the first time even when i had the bootable sd card in it didn't even boot into recovery itself i had to push "n" like crazy ... to get in ...

also if you have cwr on a bootable sd card you can use rom manager to flash cwr internally, so you wont need a bootable sd card, if you want to get into cwr just use rom manager and select reboot into recovery, i use to have cwr on my sd and didnt like it because you would have to take out the sd card everytime you boot, but this way is much easier, you can back up in rom manger instead of doing it the manual way...holding n and power button, hope this helps

[Solved-Q] Must be a moron, but I just can't get vol+/power-button to CWM-R to work

This is a painful message to write, but I am desparate. This should be so simple!
Have a U8800 standard (at least it says only "U8800" in settings/about phone.
What have I done:
- Upgraded some time ago to 2.3.5 Rev B522 from Huawei.
- Then rooted it with SuperOneClick.
- Installed ClockWorkMod from Play Store.
- Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.
- Turned off Fast boot under settings/applications
:: What worked/happened.
- Rooting went fine, ES file explorer and others get root-permissions ok.
- But got into CWMRecovery only via CWM program (Choosing "Reboot into recovery"). Never with the holding buttons vol+ and power-button during power-on.
Figured it was that locked bootloader on B522 that was the problem.
What I did:
- Followed the instructions in http://forum.xda-developers.com/showthread.php?t=1457490 (Get your pink screen back).
- In CWM Recovery flashed "update-B518-bootloader.zip".
- Got "ok installed or something to that effect" from CWM Recovery.
:: What worked/happened.
- Still could not get into CWMRecovery via button-holding. Tried reflashing the B518 bootloader a few times, but just no difference.
Read somewhere that each Huawei firmware-release comes with it's own bootloader, so lets try to install Huawei B518.
- Only place I could find the image was here http://huaweiideosx5.blogspot.no/2012/03/u8800-b518-23-software.html
- U8800V100R001C00B518G001.zip
- Had to take out the external SD-card to get the /sdcard/dload directory on the internal SD-card.
-Seems to be important to have dload on the internal SD-card and not the external.
- Booting the phone with vol+, vol-, power did not start the downgrade, but was able to trigger it via settings/storage/software upgrade.
After downgrade to B518 (Checked version in settings/about phone):
- Deleted /sdcard/dload directory.
- Rooted with SuperOneClick
- Installed ClockWorkMod from play store again.
- Put CWM Recovery 5.5.0.4 into ./cust_backup/image again (think this was unecessary. I think it was already there but did it anyways)
- Turned off Fast boot under settings/applications.
:: What worked/happened.
- The phone is now in B518 software, but still can not get into CWM Recovery via keypressing at boot.
I hold the vol+ and power-buttons all the way to "desktop" so to say, but can not for the life of me get into CWM Recovery that way. Getting into CWM recovery 5.5.0.4 via instructing CWM application to boot into recovery works fine, though.
I am drooling at the thought of ICS Aurora, but I don't dare before I can reliably get into CWM Recovery via keypress.
Sorry if this is very stupid post, but I have tried so much.
Maybe the volume buttons are faulty? Turn off the phone and try this: hold down volume up; while holding press power button as long as the logo comes up. Release power button but continue holding volume up. If it did not work, try doing same with volume down.
Yeah, do what Blefish advised you but do it while the phone is off and charging. I have a kinda broken power key and with this 'trick' it boots faster and more reliable. Keep holding the 3 buttons until you see the recovery.
Sent from my U8800
Thank you both for trying to help me here!
Unfortunately I have had no luck with your suggestions.
Re: Broken keys.
Power and volume-buttons seems to work well when the phone is on. Also when I boot into recovery through the CWM program, navigate to advanced/key-test, the vol+, vol- and power button seems to work well there too.
On pressing the power-button, CWM-R reports Key: 116
On pressing the vol+-button, CWM-R reports Key: 115
On pressing the vol--button, CWM-R reports Key: 114
So I think the keys must be ok, right?
Blefish: I did what you suggested, as I understood it.
When the phone boots, there are three stages of logos.
1. A static logo of Huawei's red "fan?".
2. A short "comet" animation.
3. An animated logo of Huawei's "fan", where some highlight flashes from left to right over the fan.
I hold the power-button in until I see the first static logo, then let go of the power-button and hold the volume-key(s).
Is this the same stage in the boot-process that you were thinking of?
I have tried vol+, vol- and both vol+ and vol-, together with releasing the power-button at that point.
Have not had any success with that, and ended on the "desktop" each time.
AceDroidX: I tried your suggestion as well.
I did this:
1. Shut down the telephone
2. Plugged in the power.
3. A "fan"-logo appears which is replaced by an animated battery.
4. Upon seeing the animated battery, I tried the various key-hold variants.
- vol+ and power : Ended up at desktop.
- vol- and power : Ended up at desktop.
- vol+ and vol- and power : Ended up at desktop.
So not much success either.
I am out of ideas... Can it be that B522 bootloader that still lingers in there, not replaced by installing the B518 software?
Well, idk what else to suggest.. Maybe your problem is here?
Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.

I remember that when i mount my phone in linux, there was a partition with just the image folder. Some files like boot.img and recovery.img where there. Try to put the recovery image in there and see if it makes any difference.
I'd like see your versioninfo, can you upload a screenshot?
You can check mine from B528
AceDroidX: When I use Remount, I am able to mount that partition as read/write so that I can copy CWM's Recovery image in there. I think it is identical as mounting it up remotely, as you do. I am after all able to boot into CWM-Recovery, just not by key-pressing? I suppose I could boot into Linux and try to mount up the partitions as you do.

hi all,
i'm using some ics roms and it seems ics supports natively vol++power button to take screenshots but it doesnt work for me... do you know if there are some custom ics rom where it will work?
thank you
Wow.. It is hard to believe.. but I have actually ... eventually found a way to get into that CWM-Recovery every time.
It is a combination of your suggestions.
I have been doing variations, trying to figure something out and eventually there is a method.
What I must do, on this phone, in order to get into CWM-R is this:
1. If the charging cable is in, then unplug first.
2. Turn the phone off.
3. Take out the battery and put it back in.
- This makes a difference on my phone, at least. I am not able to get into CWM-R wihtout taking the battery out first.
4. Press and hold Vol+
5. With Vol+ being pressed continously, insert the charging-cable.
6. Wait for the Fan-animation to finish and the "battery-charging" animation to start.
7. When the battery-charging animation is running and the screen eventually goes black, keep holding the Vol+ button for some time.
- Sometimes it works to keep holding the Vol+ button for only a second or two. Sometimes I must hold it up to 30 seconds.
7. Press and hold the power-button in addition to the Vol+
8. Wait for CWM-Recovery to start.
Thank you very much for your help.
Now I think I can try for ICS!

[Q] Cyanoboot won't load cm-10 from SD

I used leapinlar 's guide to install cm-10.2 (SanDisk 32GB class4)... but the Cyanoboot menu doesn't seem to work... I've searched here and also googled, and maybe I'm not using the right keywords because I found plenty of discussions about boot problems, just not the one I am having, which is:
I hold down the 'n' to get the boot menu. When I select to boot from the SD, the screen goes black, and after a couple seconds, it boots from EMMC instead. (If I select SD recovery then linux starts from the SD, and either installs anything I've added to the SD, or tells me there is nothing new to install if I haven't, and shutsdown).
any ideas what's wrong?

What does it do if you just let it boot without trying to use the menu? Why do you want to use the menu for going to SD when it should boot there automatically.

If I do nothing (don't hold down the 'n' button) I don't get a boot menu at all and it acts as if there is no bootable SD card.- just goes right to 'nook color'. If I hold down the 'n' to get the cyanoboot screen, and I select to boot from SD, the screen goes blank and then goes right to 'nook color' too. I can't get it to load CM10.2 at all.

That means CM10 did not install properly. It should boot directly to CM10 on SD with no intervention of the menu. I suggest you start over with a clean install of the SD. Reburn the SD and start over.

Was hoping there was some simple obvious thing I was missing... but I was afraid it was going to come to a complete redo.
Reformatted the card, redownloaded everything, and redid all the steps and it is working now. Dunno what went wrong the first time, oh well. Thnx.
