I ran into this weird problem with CM7 on SD for my NT16. My OS was updated to 1.4.2 by B&N store specialist while she did repartitioning.

I followed the instructions to download the compressed image file and the image burner program to a Windows7 PC. Unzipped both files into two separate folders. Ran the image burner to burn the image to SD card that was in the PC's SD bay.

I could use this SD to boot into CM7 only when the NT16 was connected to the power cable that was plugged into either outlet or PC. However after it booted into CM7, it stayed in CM7 even when the power cable was disconnected.

When it's not plugged in, it booted into NT environment. When rebooting from CM7 without a power cable also sends it to NT.

These are files and folders right after SD image was made and before inserted into NT16:

flashing_boot

boot

MLO

u-boot.bin

Android (folder)

.android_secure (folder)

LOST.DIR (folder)

Is it supposed to be just like that or I missed something?

[Barnes & Noble Nook Tablet] freonchill:
did not see anyone with this same problem

Which install are you using: SD

What version is your CM7 download that you are using (should be alpha final now): Updated Final Alpha build March 7th

Do you have any mods on your NT: none

Where is this bug (main system or which application):

this is my co-workers NT16; set it up on monday, she has been running it since. today it wont boot to the SD, well it does, but fails...

power plugged in, power on, see "n" screen, see team-B xda screen, see cm7 boot logo, then black screen and then reboots to nook software

cant finish the boot sequence into cm7 via SD

Can this bug be easily replicated: every time it boots with power plugged in

If yes to above how can we replicate it to check: not sure?

the nook software can read the files on the SD, so i am pretty sure the SD card isnt corrupted. not 100% sure if the battery ran down caused this problem, or if its just incidental, but it did get down to 14% where it would not power on without plugging in the charger.

guess i need to know if this has happened to anyone else or i should just wipe and rewrite the IMG to the SD card and start over.

I can not get CM7 to boot on my nook tablet

I can not get this to work,my nook will see the SD card but will not boot to it. I have tried two different 8gb cards,both san disc,both new, purchased from different places. I have used two different computers, with different OS, Win7 pro and XP,used two different imaging software, diskimager using the link from XDA, and winimage .I have formated the disc on the nook and then added the image, I have formated on the computer,both of them,and then added the image,I have extracted the zip using different programmes and nothing makes any difference.The nook can read the SD card and shows the files but won't boot. Any ideas?

Just to say thanks, I did as suggested below,plugged in the power cable and it booted just fine. Setup app market and wi-fi etc. Thanks to all involved. . One think, ass everything seem to be on the sd card does that mean the bigger the sd card the more storage you have
[Barnes & Noble Nook Tablet] tmlee51:
Try to boot it when the power cable is connected and plugged in to either outlet or PC. If it boots into CM7 that way, then you have the same issue that I have (see my post above). If not, you have something different.
[Barnes & Noble Nook Tablet] PlacidCat:
Yes, and from what I've seen, it's a known issue and likely due to new IROM for the OMAP processor (according to AdamOutler):

[Barnes & Noble Nook Tablet] downsay:
Each time i reboot Thumb Keyboard stops working and continuously force closes. I have to do an uninstall and reinstall each reboot to get it back up and going. This was not an issue i experienced with the earlier release of Alpha CM7. I did wipe data/factory reset and wipe cache before doing this install. I did not restore from titanium backup any data. I did a fresh install from the Amazon appstore of thumb keyboard. Installing as a system app did not make it hold after reboot either. Nor did changing app permissions.

Does anyone have any insight into this? Thumb keyboard is by far my preferred keyboard for the nook tablet.
[Barnes & Noble Nook Tablet] Know-Fear:
Just a suggestion, have you tried adding the cyanoboot files to your bootable sdcard? On my bootable sdcard version of cm7 (used only for testing purposes as I have mine installed internal), I used the cyanoboot loader and can select whether I want to boot from internal or from sdcard from the menu there.

To get to the menu, push power, wait for the n, then hold down the n button until you get to the menu. n button moves selection down, power button selects option. Give that a try and report back please.

[Barnes & Noble Nook Tablet] movrshakr:
If this is not where to ask, please point me to where usage questions should be asked...

Running on microSD card built from the alpha thread. Works great. Repartitioned yesterday at B&N to 8GB.

Questions relating to the file structure:

a. When I open a file manager ("ES File Explorer" or "File Manager"), am I looking at the internal device memory or at the card?

At root I have an

/sdcard folder (11 folders + files), a

/mnt/sdcard (11 folders + files), and

/sd-ext (empty).

b. If I want to sideload documents for reading in Nook app, where do i put them?

c. Does using Calibre simplify any of this?

d. How do I move 'stuff' from the Nook area to the CM7 card storage? (The items in B&N account are not much of an issue as I can download them again while booted into CM7.)

However, this morning, while at a place with no wifi, I opened the nook app. All books had a generic icon with title. I thought I had not download'ed them into CM7 side. But when I got home and on the wifi, the book icons were all normal, and the books ARE already there. Huh?
[Barnes & Noble Nook Tablet] perry0718:
I think I've semi-solved the NT boot issue.

Two comments I posted on liliputing.com's page regarding CM7 installation on the Nook Tablet.

I thought they might be helpful, since some people seem to be having an issue booting CM7 on the Nook Tablet

The first:

I was able to boot from the SD card, but ONLY when my Nook Tablet was plugged in to the power cord. Once I removed it and went to battery, it would boot into the usual TB environment. Also, the 'Reboot Into Recovery' for gApps installation didn't work, either. The Nook would halt the startup and ask me to try rebooting.

Any suggestions? I'm running a Nook Tablet 16GB, OS 1.4.2, with a 32GB Class 10 SD Card.

The Second:

I just went out and picked up an SanDisk 8GB Class 4 Micro SD card and

performed the steps above. Everything worked just fine and I

was able to boot into CM7 without a problem. This tells me that the

problem lies either with the brand SanDisk vs Lexar (the 32 GB card), or

the Class (4 vs 10).

The only other issue I've seen is that rebooting the Nook causes it to

go into the Nook environment, while a cold boot will launch CM7. Not an

issue, except that I can't perform Step 5 as listed above because I

cannot 'Reboot Into Recovery'.

Please pass this along, and if there's any suggestions for installing gApps, let me know.

I just got my nook today !

it is running 1.4.2

I want to get CWM and root and then flash CM7 internally and permanently so that CM7 is the only thing on there I want to get rid of the original software ( I will make a back up of course just in case)

I am only confused though on what is the best thread to follow or instructions to follow to do this. I see many root instructions but they do not seem to show how to install CWM,

I assume I need to first root, then install CWM?

any pointers in the right direction would help. Again I am on 1.4.2

The quickest way of booting in CWM and writing CM7 internally would be to write a bootable sd card for CWM:

http://xdaforums.com/showthread.php?t=1446987

Though do take note that with the newer devices, it's observed that if you want to boot from the sd card you would need to power on the device via the charging cable that's connected to a computer or wall outlet

Once you are in cwm, just flash CM7 per instructions from this thread:

Hope that helps
[Barnes & Noble Nook Tablet] Cubanluke88:
1. Put CM7 zip file + gapps (if you want google apps) on the internal memory of the nook.

2. Create a bootable sd card for Clockworkmod recovery.

3. Use sdcard to boot into CWM and flash the cm7 zip/gapps. Make sure to do a data wipe.

4. Boot into CM7. Use indirect's app to flash CWM internally. Reformat external sdcard.
[Barnes & Noble Nook Tablet] freonchill:
from what i have found, it will only boot to the SD on power (adapter or computer). assuming you dont run into a SoD (sleep of death)*, its not a big issue, b/c you dont shut it down everytime you "sleep". though i did run into an issue on my co-workers, were it starts booting to cm7 (xda boot screen, cm7 boot, black, reboots to NT software); dont know if the SD card has an issue or what; i had posted earlier today, havent seen an answer; ive got a couple 4gb sd cards, might just start over for them and see what happens.

*not sure if the NT has the sleep of death issue that the NC has; just using it as a frame of reference.

gapps is included in the SD 4gb img; i know, its odd, as we have been conditioned to install it separately.

see this topic about the non-equality of SD cards. in short, sandisk are great, others might or might not be fast. slow = lots of FC. you can always format and do a crystaldiskmark test on your SD; you want the random write QD=32 to be higher; typically, greater than 0.8mb is good, most sandisk are 1.2mb or faster; some cards can be as low as 0.001mb.

see above for crystaldiskmark benchmark on your SD

i do not think that the boot from the SD img that this is the support post for does not have any boot options or recovery.

see above

Nook tablet is no longer booting after CM7 boot loop and forced off (power + n)

Which install are you using (Internal or SD): Internal

What version is your CM7 download that you are using: alpha final

Do you have any mods on your NT: Not that I know off, besides CM7 of course

Where is this bug: main system not booting

Can this bug be easily replicated: it is reproducible on my device

If yes to above how can we replicate it to check: I don't know

Description of the bug

1.) Nook tablet 16GB version shipped with 1.4.1

2.) Automatically updated to version 1.4.2

3.) First rooted ROM installed using the R3 card

4.) CM7 alpha final installed, worked fine for a few days

5.) CM7 was in a boot looped, forced off with power+n button for 20s

6.) NT is no more booting. Screen stays black. Tried all different button configurations. But no chance to get it back to life again :(

Maybe somebody did observe the same.

I am happy for every hint how to bring my NT back to life. Maybe there is a button combination I have not yet tried. On my system I always needed to hold power + n button to boot from the SD card. But this is now no longer working either.

Solution: Thank you tonyp22!

I did connect my NT to the charger with the bootable sdcard inserted and walk away. When I came back the NT booted into CWM.

I do not know exactly what happend. Maybe my NT was in a boot loop or crashed. Then eventually, once the battery was empty it completely switched off.

I did now install again a rooted stock rom (1.4.0). I will probably continue testing CM7 just installed externally on a sdcard.
[Barnes & Noble Nook Tablet] Know-Fear:
Does it boot normally with the sdcard removed?
[Barnes & Noble Nook Tablet] try_and_error:
No, unfortunately the NT does also not boot when I remove the sdcard. The screen just stays black.

To be honest, in the beginning I was not sure, if the screen is really of or still one and black. However, meanwhile I think the screen and the device is really off.
[Barnes & Noble Nook Tablet] Fillimerica:
SD Card Boot Observations

I have the same boot problems that have been widely reported. My observations are that it is definitely SD card related in my case.

I have a Sandisk C4 8gb that I bought from Radio Shack. I can load CM7 and boot with no problem (from the img using winimage) and I can boot CWM from the SD using the wipe/copy method from indirect.

I also purchased a Patriot C4 16gb card from MicroCenter. I tried to load the exact same two boot approaches mentioned above using the same computer and neither CM7 nor CWM will boot without the USB cable plugged into either the wall or a PC.

My nook was purchased in late December.

I'm playing with both SD cards at the moment, so I can run tests, reformat the cards and/or the nook if the devs want me to try to isolate this further.

Since this is clearly a boot sequence problem (both cards work fine in the Nook once booted) perhaps it is a situation where certain SD cards aren't ready to provide data early enough in the nook boot sequence when on battery, and adding the USB cable causes the boot loader to perform an additional task that introduces just enough delay so that the "bad" card is ready.

I have not benched the cards relative performance (could do that tonight) but I have not observed any performance difference in the nook when running CM7 on either card.
[Barnes & Noble Nook Tablet] spcagigas:
You should be able to force your nook to let you select the launcher by going to \Settings\Applications\Manage applications\ADW Ex\ and tapping the "Clear Defaults" button. The next time you tap the home button, you should get the familiar pop-up asking what application you want to use to complete the action.

Alternately, you should be able to find an app called "Home Switcher" in the Market that lets you select among multiple launchers. CAVEAT: I haven't used this on my nook, but I use it routinely on my DroidX with no problems.

Dolphin HD Sonar Activating Too Often on CM7

Ok I think I have an honest to goodness bug report, unfortunately I have no way of knowing whether it is related to CM7 or the software I'm running. Here's what happens:

While using Dolphin Browser HD, sonar will get activated for no reason at all (it seems). The tablet is laying perfectly still and there's nothing touching the corner of the screen to activate sonar. Yet, when I try to open a new tab, inevitably the sonar option pops up, and even if you click cancel, it comes right back!

It is repeatable and the only thing I will have open is an instance of Dolphin. My install is of the Alpha Final internal. Could this be a Dolphin issue? It's possible. Could it be a CM7 having to do with the accelerometers not detecting movement correctly? It's possible. Has anyone tried any games that rely on the accels? I don't know, and I'm not a coder. I have no way of telling from whence the problem stems, hence I'm posting this here for anyone else that may have the know-how as to how to deduce exactly what is happening.

I will say this, it is annoying to the point where Dolphin is unusable, so I may just switch to Opera until there's a fix, or Sonar is gone.

primarily the number you are looking for is the Random Write 4KB (QD=32) being greater than 0.8mb; preferably greater than 1.0mb; most sandisk are greater than 1.2mb.

formatted a new card (physically separate card) to let my co-worker use her nook with cm7 again. we will see if it happens again

side note: i noticed that in cm7, reboot reboots to nook (even when connected to power). so technically, to get cm7 to reboot to cm7 you have to shutdown and then power it up again. can anyone with a sandisk SD card confirm that this is true?

...That is the way my card works. The only way into CM7 on the card is to boot from power off. I do not have to be plugged in for mine to boot to card (SanDisk 8GB, class 4). Any boot not from a power off state goes into native Nook.

Hi, I'm running the sd card version. Is there a way to turn down the minimum brightness as it a lot brighter than the stock rom.

[Barnes & Noble Nook Tablet] freonchill:
i use elixir, and the widget allows you to set brightness by number

i have it set to 10% for my nook color. it should work the same for nook color. if the default (default on nook tablet is ~30% in cm7) for the NT is too much, try changing to to 10, 20, 30... or maybe 1%!

Try plugging the charger into the NT, wait about 15 minutes, then see if you can power on the device.

I was actually wondering if this is still valid for the NT as it does have different hardware. I have experienced better performance from a Patriot C10 vs Sandisk C4, which is opposite from the NC. The NC always seemed to do better with the Sandisk cards with higher seek speeds.

Ok....so thought i would test to see how long my batt would last. I am running cm7 internal withthe latest build. I have watching my wifi and the batt useage. I have the wifi to sleep when the screen turns off and the display is set to turn off after 5 min.

So I was at about 35% or so last night. Turned it off and this morning it was completly shot. Here is a screen shot of the usage. I am thinking i might need to wipe the batt mem for the rom?

Well not that this is an issue or a bug but wantedto share what i am seeing.

Look how the batt just bombs out.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
I noticed that battery life while not in use was not as good as it had previously been so last night I charged it up and left it in my hotel room. Went back a few hours and it had already dropped quite a few percent so I did the following

Made a full backup in cwm

In ES file explorer

Rename telephony app and also anything phone related in /system/app (just changed .apk to .old) this does cause crashing and requires forced reboot by holding power till shut off, once rebooted it should be fine. I also froze everything that started with dialer using Titanium.

I then installed the free version of Juice Defender and just clicked through it enabling what could be (seemed to all be default settings)

I then enabled airplane mode and turned wifi back on after doing so.

Put the NT back in the room and left it there till this morning. I brought it down to reception this morning, woke it up and let it reconnect to wifi. It was still on 99% I've used it for about 3 or 4 hours today maybe more all just internet stuff, its currently on 65% do battery life is back as it was. Only issue now is after a reboot because its in airplane mode you have to manually enable airplane mode. Hardly and issue. Not 100% sure which bit improved the battery life but I'm assuming it will show its head when I begin to really enable everything one by one when I'm back home :)

Currently I'm dual booting CM9 with CM7 on SD.

So regarding the SD card version of the final Alpha build, the first partition created on my SD card shows 190MB. Is this the partition that I would want to extend to allow SD storage while in CM9? I believe it is, just trying to make sure.
[Barnes & Noble Nook Tablet] nook_lover:
No, the one to extend is the 1.30 GB fat32 partition.
[Barnes & Noble Nook Tablet] Solar.Plexus:
^Are you sure? My third partition is 1.40GB as Ext3.
[Barnes & Noble Nook Tablet] nook_lover:
It's the fourth one to extend and it's 1.30 Gb.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
CM9 would be recognizing your boot partition as the SD card, so yes its the one you are talking about. It would be a long process to extend that one though because all the others are behind it. You could alter the cm9 system to use the same 4th partition on your sdcard that cm7 uses though, its a little bit of work but would be a worthwhile modification in the long run :)
[Barnes & Noble Nook Tablet] freonchill:
you can hold the power button for 1-2 sec in CM7 and it will bring up a menu that has stuff like airplane mode, screen shot, reboot, shutdown

just select shutdown. and if you want to reboot; then make sure the power is in (power can be adapter or pc) if you want to boot up in cm7 from SD rather than NT native OS. reboot will reboot to NT not CM7, even with power connected.

interesting, i thought that for performance of sd cards in general was the random write 4k, QD=32. not so much specific for any given hardware. obviously there are differences in the hardware that the micro-sd is plugged into... but i though it was always more of a micro-sd standards think, like how a 7200rpm drive is almost always faster than a 5400rpm spinning drive. or perhaps like how the current generation of ssd are faster than earlier generations due to the change of controllers and the way they utilize the specific memory chips, which themselves are similar to those used in sd cards.
[Barnes & Noble Nook Tablet] movrshakr:
Not all of us have to have power in for the card to boot the CM7 on it.
[Barnes & Noble Nook Tablet] Solar.Plexus:
Okay, so we must not have the same partition layout on our SD cards. Thanks though.

I guess I could extend the boot partition with Partition Wizard, but I'm liking the idea of leaving the boot partition untouched and using the same SD storage on both ROMs.

Could you point me in the right direction of what to change in CM9's system? I'm guessing it's not so simple as modifying the CM9 build.prop.

Also, is CM9 recognizing the boot partition as my SD card just because it's the first partition on the disk?
