I am answering my own question above. After exhausted all workarounds that people suggested on this board, I had a feeling that it had something to do with the timing of the MicroSD card that I was using which was an 8 GB Kingston Class4 card. I decided to give the SanDisk 32GB Class4 card a try since it was recommended by many. After transferring the image from my 8GB Kingston card and extended the last FAT32 partition on the new 32GB card, I inserted the card and turned the NT on. Guess what, it booted right to CM7 without tethering! All my apps also ran noticeably faster! Hopefully, this will also solve many other folks' booting problem. Since I have fewer than 8 posts, the system does not allow me to post a link. To find the card that worked for me, just do a search on Amazon for "SDSDQM-032G-B35". I bought mine from KEFERS (received in 2 days), but I guess you can also purchase from others as long as it is the same part number.

@mdpark84,

This is good advice. In addition, if you know you're going to be away from your tablet for a while but still want to keep it running, try getting in the habit of manually turning wifi off. Wifi and the display are the 2 major battery life killers.

is my SD card/data toast?

Thanx to all for the CM7 work. I've been a lurker since the early NC days. I still use a dual boot Nook Color CM7/CM9 as my old reliable. I've done lots of reading perhaps not each and every post but there are still get confused and mess up some my my cards. I've been running CM7 Team B Alpha Final from SD cards only since March. (FYI I never had the USB power on issue from an old Sony 4gb or Sandisk 16gb 4 (x2), Transcend 8gb (10)). I use the other cards to run specific other apps or roms. I've also noticed that some people have reported that cards >16gb are kinda buggy...not promising for my problem I guess.

So I have a 32gb Sandisk 4 that has been my daily. I need to keep my Nook Emmc to play/record kid books for my niece. I lent my NT to my brother. I showed him how to remove the SD Card or just go to the "reboot" to go into stock NOOK (1.4.1). He was using the CM7 to play games and surf the internet. In retrospect I should have given one of my other CM7s to play with not my daily 32gb. but now I have the same problem noted by mraymer77 Post #743. I boot with or without holding the (n) and I get the silver "n" then TEAM B splash then Android CM7 ...the arrow goes around appox 3.5 times then it goes back silver "n" and boots into stock. My other CM7 SD cards work fine.

So is my 32gb SD card toast? or is there anyway for me to pull that data off? can I recreate another 32 gb SD card and copy the boot.img or the first partition from one card to another to rescue it? I do have Titanium backup for the apps and the data from over a month ago. I just wanted to know before I toss that image.

thanx for your time.
[Barnes & Noble Nook Tablet] ha2fb:
Sorry, I believe my terminology is a little off...

I have one SD card that I use to gain access to CWM (Indirect - method) and the second card that contains nothing but the zip file itself (img).

I'm confused by what you mean "burn it onto a card"

Do you mean use WinDisk32Img utility? I was under the impression that you copy and paste the zip onto the sd card (ensure that you don't uncompress, because CWM will do this) then you select the proper command which would be update from zip card.

Am I wrong on this assumption?
[Barnes & Noble Nook Tablet] movrshakr:
If you want to MAKE a bootable microSD from which you can boot into CM7alpha, then you extract the img file from the zip and burn it (write it; not copy it) onto the card. I think WinDisk32Img will do that; I use a different program just because I always have.

If you want to flash something onto the internal ROM, you use CWM to flash a zip file.
[Barnes & Noble Nook Tablet] ha2fb:
Thank you for the clarification. I was attempting the flash method, but I receive an installation aborted error when performing this. Do you know why this would happen?

More info: CWM 5.5, NT (16gb) 1.4.2
[Barnes & Noble Nook Tablet] movrshakr:
No. Are you using the correct flash zip? There is a different one for internal vs. for the card.
[Barnes & Noble Nook Tablet] ha2fb:
Yep, I'm using the SD version.

"SD VERSION IMAGE

Download HERE MD5 1e1932c49dda7345a5575de2612af30a"
[Barnes & Noble Nook Tablet] movrshakr:
Wait wait wait!!!!

You said you were trying to FLASH. If you are trying to flash to internal, you DON"T use the SD card version.

I am again very confused what you are trying to do.
[Barnes & Noble Nook Tablet] koshawala:
I downloaded the sd version image. However, I am getting the following MD5 Hash: f97fb4d14bbe2ea606d0e78024fc7a51

Unfortunately, my nook tablet (8gb, 1.4.2) could not load CM7 from the sd card (sandisk, class 4, 32gb). What am I doing wrong?
[Barnes & Noble Nook Tablet] movrshakr:
Not nearly enough info to answer your question.

the md5 for my copy of the IMAGE file Team-B-CM7SD-Alpha_final.img

is f97fb4d14bbe2ea606d0e78024fc7a51 -- the same as yours. So that should be a good file.

What exactly is it doing? How exactly did you build the microSD card?

Did you read through the thread (or at least part of it) for ideas?
[Barnes & Noble Nook Tablet] mdpark84:
If this is a continual problem, it is your SD card
[Barnes & Noble Nook Tablet] koshawala:
Thanks for your quick response. Yes, I read part of this thread and the rom thread. I got the zip from the first post of the rom thread. I wrote the image using win32diskimager (where I found the MD5 hash). I turned off the power. Put the card in and turn on. It's always loading from the stock rom.

Do I need to hold the power button 20 seconds to power off completely before inserting the card?
[Barnes & Noble Nook Tablet] movrshakr:
Yes, the Nook must be completely in a hard off state before putting a card in or out (this is a personal policy; others may feel differently), and, once you have a working card, it will only boot into the card from a completely OFF state, then pwr on button--not a re-boot.
[Barnes & Noble Nook Tablet] koshawala:
In fact I tried to power off completely. Then use the power cord for it to turn on. It's still loading from the stock rom.
[Barnes & Noble Nook Tablet] movrshakr:
Is it showing any evidence of trying to start booting from the card?

I would suggest getting an 8GB Sandisk class 4 or 6 card and trying that.
[Barnes & Noble Nook Tablet] sho0318:
I would rewrite the image to the SD card one more time to make sure that the image was correctly written to the card. An error may have been introduced during the write process for whatever reason.
[Barnes & Noble Nook Tablet] ShinnAsuka:
two things i have noticed ever since flashing final build. using internal install btw

1: when using root explorer, it appears that the months and days are not shown. i did not have this problem with the previous build. i will try reinstalling root explorer to see if that changes anything.

EDIT: reinstall didn't solve problem 1, any ideas?

2: when holding down the power button, you get a menu and one of the options is to reboot. in the final build version i only have one option when rebooting which is simply to reboot the system. however, in the previous build i was able to reboot into recovery. As of right now I am pretty sure that I have flashed CWM to internal.

EDIT: curiously, the titanium backup widget has the option that lets me reboot into recovery...

Any one else experience these minor hiccups?
[Barnes & Noble Nook Tablet] succulent:
Previous CM7, Alpha 12 is is CM7.1. Alpha Final, or as I called it CM7.2 RC0 is completely new. It's compiled CM7. I would suggest doing a wipe/data/factory reset in CWM after backing up your data for a fresh start.
[Barnes & Noble Nook Tablet] ShinnAsuka:
the process i used to install new cm7 was this:

back up current rom

install from sd card

wipe data, cache and davlik

was i suppose to wipe those 3 things before flashing the update?

In the instructions on the 1st post it said to wipe after flashing.
[Barnes & Noble Nook Tablet] bocaccio:
Question:

I'm on cm7 Alpha 12; Whats the best way to get the b&n app to act like the stock b&n reader app? I want it to sideload all my books from sd card and pick up where i stop reading..etc..

I made a shortcut folder on home screen w my books in it but try and open and gives error msg.
[Barnes & Noble Nook Tablet] succulent:
Doing just the wipe data/factory reset is fine. Wiping data/factory reset before installing rom/after installing rom does the same thing. All it does is format your data partition. Backing up your data refer to using a backup app to backup your data.

You previously installed CWM into internal system and now that settings is gone, you have to reinstalled it.

Root Explorer is out dated IMO. Use ES File Explorer. It has root setting and it's free.
[Barnes & Noble Nook Tablet] ShinnAsuka:
oh ok, so i can just reflash cwm with indirect's cwm flasher and that option should pop up again in the reboot menu right?

i would use es file explorer, but root explorer's ui is just so much more simpler.

EDIT: hm... es file explorer does seem to get updated more often. i'll try it out. thanks for the suggestion.

UPDATE: RESOLVED alpha_final not showing /mnt/media in storage or allowing USB storage access.

Thanks to Succulent for providing the solution to this here:

Please give him a "Thanks if this information helped you!

Original post is below.

Ive got that, also. I liked having the reboot recovery option in the power button menu.

BUT, what sent me running (while screaming like a noob :( ) back to Alpha 1.2 was that my /mnt/media partition was not being recognized under "storage" in settings. It said I had "3.97 GB" available internally, and that was it. Also, I could not access that partition through windows on my computer.

Background info: I repartitioned recently, using this guide: http://xdaforums.com/showthread.php?t=1531120

Any ideas? I'd really like to reflash the alpha_final, but not if I can't access my internal storage. :(

UPDATE: Reflashed CM7 alpha final (thought that maybe it was a bad install...) Still doesn't recognize my mnt/media in settings>storage, and my computer only recognizes my sdcard when it's plugged in through usb.

Thanks for your release, guys! I've just installed the internal release and it seems the hardware decoding of h264 (MX Video Player) still doesn't work the way it should, at least with the .mp4 files encoded with h264. There are noticeable downscaling problems of FullHD videos and the playback is not smooth at all. There were no such problems on stock :( Please confirm if anyone else has it.

I can't get H/W decoding but I'm going back to verify what worked previously. I know ones that H/W decode with DICEplayer on my SGS2 won't H/W decode on the NT CM7 Final.

[Barnes & Noble Nook Tablet] plantucha:
My bug report :

All partitions formated before flash, MD5 checked

Internal Alpha final

this is my diff with alpha12:

I'm using pin code to secure NT.

But sliding screen unlocker is still there.

Skip on security checked/unchecked doesn't matter.

(can be because cm7 upgrade it was working ok with alpha12)

Soft keyboard missing some numbers and acting strange.

Reboot to recovery missing.

for some reason wifi got SOD while plugged and charging overnight

with settings: sleep when screen off. Same like on alpha 12.

NT was still working but wifi was reporting turning off forever.

after try to reboot it just hang rebooting.

in 20 min browsing+facebook battery is at 90% only

(can be batt calibration because full wipe)

Wifi is slower than last build.

(can be just subjective)

OR maybe just bad flash. I'll try later again.
[Barnes & Noble Nook Tablet] dang69:
I still think there might be some funkiness with lockscreen. I haven't used a PIN but when I enable it the "N" button doesn't always turn the screen back on as it did in the previous build. I'll pay attention and see if there are any related events and such.

Certainly not a deal breaker. Just a momentary drop in my stomach when i hit N and nothing happens.

Yes. Workd this time after wiping off the card and rewriting the image.

Now your confusing me! After I'm in CWM using the first SD card, I eject and insert the second SD card that contains the zip file. From there I follow the instructions concerning installation...

1. Goto install zip from sdcard

2. Choose zip from sdcard ( if CWM hasn't recognized your SD card you need to eject it and re insert it once or twice, sometimes you need to go to mounts and unmount SD, pop it out and back in then select mount sd)

3. choose the Nook-Tablet-CM7-Alpha-Final-TEAM-B-signed.zip

4. scroll down and select Yes - Install Nook-Tablet-CM7-Alpha-Final-TEAM-B-signed.zip

From step four I receive installation aborted. I've tried on two different SD card's containing the zip file (both 4gb). I have yet to deregister the device and start from scratch...

thoughts?

[Barnes & Noble Nook Tablet] movrshakr:
Exactly. We are totally confused as to whether you are

1. trying to flash CM7 to the internal memory,

or

2. trying to make a microSD card which can then be used in the Nook so it boots into CM7 running off the card.

If your desire is the former, you DO NOT use the image you cited.
[Barnes & Noble Nook Tablet] miniblue:
There are two zip files. The zip for internal gets copied to the SD card and flashed with CWM. Under the SD version is the second zip file that has to be unzipped and the resulting image file written to an SD card which subsequently you boot from into CM7, hence SD card Version.

Are you by any chance trying to flash the SD version zip file with CWM? THAT WILL NOT WORK!!

How To Return SD Card To Normal

I used the SD Version to try out the CM7, it worked fine (thanks everyone for their hard work!) but i prefer just to have the rooted version of the Nook. My question/problem is how do I restore/format my 16gb MicroSD back to its normal state? I've tried everything I could think of (even Unbutu gparted, I'm a noob on that maybe wasnt doing it right) and I can't get it back to its normal useage. It seems like it is write protected (the hardware lock switch is off) because i can't delete or resize any of the four partitions on card. Any help is greatly appreciated and thanks to all in advance...
[Barnes & Noble Nook Tablet] digixmax:

Random reboots

I'm not sure exactly what is causing this but I get at least 5 crash/reboots a day.

I have a 12 GB PNY microSDHC class 10 card on an NT8. The card isn't terribly fast so the system behaves a bit like a modern OS running on not enough RAM.

I'll be using CM7 and it's usually when I have it perform some tasks when it reboots itself. Once that happens I often have to mount the SD card to my desktop and fsck -fy the partitions before it'll boot reliably again. I've had it be such that I'll boot the device, hop onto a shoutcast station, then have it promptly reboot itself. Quite frustrating.

Being brand new to the Android-sphere I really don't know what to do. Is this the kernel freaking out? I'm not sure but I don't think I always have wi-fi enabled when it happens.

I searched through this thread but couldn't find anything on the issue (apologies if it's already brought up).

Thanks for any help and thank you so much to all of those involved in getting this up and running.
[Barnes & Noble Nook Tablet] Keithn:
I've had no issues like that. My guess would be the SDcard is failing. Also a class10 should be faster read/write but from what I have seen are more prone to having issues. If you have another card to try with I'd do that.
[Barnes & Noble Nook Tablet] movrshakr:
I concur with that. Cards can work or not. They can work well or not. Class seems to make not much difference.

Unless you have a lot of time into customizing your system, I would say to back up apps and appdata with TitaniumBackup, then build a new card. You could try a rewrite onto that same card, or go with a different one.

I use a Sandisk 8GB. Some here believe that the Sandisk cards have a better, but not guaranteed, chance of working.
[Barnes & Noble Nook Tablet] drspinderwalf:
Thanks a lot for the replies. I have heard (since browsing around raspberry Pi forums) that class 10 isn't very well suited for something like an OS as they are optimized for cameras taking one picture at a time. The card I have now is brand new but I was beginning to suspect it being at fault as well (especially since I couldn't find anyone else having the issue).

Can't wait to just wipe the blasted internal :).

[Barnes & Noble Nook Tablet] Keithn:
True, class 10 is supposed to have better speeds, but for it's sequential read/write speeds it seems to sacrifice some of it's random read/write. I've looked around and the class 4-6 seems to be a good choice, the 10s seem to have more mixed reviews.

I am new nook tablet user. I have tried many times to install CyanogenMod 7but I have not succeeded, I followed the steps found in this forum but still could not do it. Can someone help me; Thank you.
[Barnes & Noble Nook Tablet] raywaldo:
internal or external?

You do not state whether you have an 8gb or 16gb version Nook Tablet. If it is the 16gb version then you should be able to flash the rom to the INTERNAL (emmc) memory. Since I have an 8gb Nook, I could not help with that.

However, if you have th 8GB version - DO NOT ATTEMPT to flash the internal version. The link for the sdcard version is down but if you have that, then it will work but you must create a bootable sdcard by burning the (zipped) image to the card. This is very confusing and complicated and depends largely on the brand/class/size of your SDCard. The Sandisk 8 (or 16) gig class 4 (or class 6) cards seem to work best.
