Hi All,
I have been using Android for a while now, with no real issue. After changing my DPI I found I could no longer use my old build (Black screen) after booting into Android. Now whatever build i choose I cant boot past linux with it errroring out at
"superblock could not be read or does not describe correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an altanative superblock"
Seraching the forums I found this means I have no/corrupt intrid.gz, so i redownloaded and formatted my SD card and to still no avail.
Is anyone able to assist? Devs?
Thanks alot to all the devs that built these great ports, now I cant stand being without Android.
Things Tried:
- Task 29
- SD Re-Format
- Different Builds
- Left to run for ages hoping it will pass
- Tried numerous times
- Tried an older build
- Tried class 2 (Currently using class 6)
Have you ever think of reflashing winmo and start over again?
To be honest, no... I havn't changed anything in winmo though, and didnt think that would affect it?
try delete Android folder, not Android App. see what happens. everytime mine didn;t boot i did that and it boots. dunno what it is but it just work

Thanks mate I tried that, I just backed up ma lil guy so I'm going to try a reflash and Task 29. Will report back.
Hey Guys,
I really need help! My Haret is getting stuck still at the same point trying to boot linux after Task 29!
Are there any other powerful tools than Task 29?

I have tried the class 2 16gb and my usual class 6 8gb, its driving me crazy. What is the conventional method of formatting an SD card? I use panasonics SD Formatter?

Go into windows mobile start menu tools format sd and go from there. Looks like some screw up on your sd card.

Hey Mate thanks for that i just tried it and still same error message... I've resorted to playing games on my GF's iPhone...
Hello, my phone can only boot 10% of builds released.
try the same as you:
-hspl
-mtty
-change WMO ROM
-differents SD Cards.
The only builds that i can boot are:
-mattc1.7
-mdeejay froyo sense 2
if you didnt try it, do it if you can.
Thanks, Unfortunately I have tried those and I'm running HSPL3.
I have updated the first post with the things i have tried to fix this...
Back to playing games on my girlfriends iPhone...
Dont know if this helps, it also says:
"/bin/sh: can't access tty; job control turned off"
Are you using any of the builds which create their own 512MB/1GB/2GB datastore? Those may take up to 30 mins or more to complete the initial config and show up the GUI

check your startup text file. It might've changed somehow. I should show where android is supposed to boot up. ex: [ set cmdline "rel_path=Android" ] or whatever the name of the folder where android is located. I've got two going right now. One in a folder called AndroidJ for JDMS' v1.7 and another folder called HyperDroidv1.5. I've used quickstart android apps on the winmo side and sometimes they screw up the "startup.txt" file. Make sure that what's in the "startup.txt" is the same name of the folder where it's located. One last ex: for my android that's located in the "AndroidJ" folder, my startup.txt reads: set cmdline "rel_path=AndroidJ"
Because of the apps/shortcut/whatever you can use to boot up android in winmo mode have messed up my startup.txt, I now just use file explorer or total commander to go to the actual folder and hit CLRCAD and then HARET.exe.

Answers to "can no longer boot any android Build"
Okay I had the same situation but the way I fixed that was to
Turn off my Device
Push Volume up/down at the same time and then push the end button and hold it until it you see an icon on you phone and press vol/up again. and confirm yes
after that let the phone reboot again and turn it off
and now you press only the DOWN/VOL and END button at the same time. and now you are taking to the HSPL to Flash your Rom again.
Flash a WinMO rom of your choice. and let it reboot.
after that you need to reformat your SD card and uncheck the QUICK FORMAT let it fully format the SD card
and after your SD card if finished.
Download An ANDROID Build of your choice and enjoy!
I hope this helps
and sorry for the poor english

Based on the info I know/see it seems your device software is compatible with Android. So try this:
1. Format your SDCard with FAT32 (backup your data first) (what kind of card do you use? (size) (some users mention to have troubles on 16GB SD cards))
2. Copy your android to your SD card (read the installation guide of the chef, not all Android Builds runs from /Storage Card/Android)
3. Run CLRCAD.exe and then Haret.exe.
4. Be patient, it will take a few minutes at the first boot.
5. if you complete the setup process reboot and then you can do what ever you want.
Normally this must work.

First of all get start on a other SD, to much peoples have problems with that.
Format SD: (tittle is deferent but it is the same way)
Backup date? copy it to your PC
Attention if you have a software like Navigation software on your device there are mostly a protection key placed on your device (anti piracy) so don't format your SD, you will loose your installation key!

*ALL THE USUAL DISCLAIMERS AND WARNINGS*
*THIS IS FOR VERSION 1.1 ONLY, DON’T TRY ON 1.0.0 OR 1.0.1*
Credit goes to: GabrialDestruir for the original auto-nooter, GLa’DOS for the boot animation, pokey9000 for nooter, Mistar Muffin for Market and GTalk Fix, clockworx for the “non-ugly” patch that is used to get androidID, mastapsi for testing and coding of the original auto-nooter, lewellyn for coding, [mbm] for ABI Fix, Hotaru for the Gingerbread keyboard, rpollard00 for DroidX keyboard with bigger font, bpk for Soft Keys, Ben74 for NookColor Tools which enables Non Market Installs and re-enable of ADB , Freenode's #nookcolor chat for code checking. A special thanks to all developers out there, without all of you this community would not be as great as it is.
Please Note: If you are the developer of an app that is included in this work, and would like me to remove it, feel free to contact me.
*I am copying the following step from the original auto-nooter, because they are tried and true, and people are already familiar with seeing them*
What it does:
Installs su and Superuser.apk
Installs Busybox with whoami
Installs Softkeys 3.0.6
Installs NookColor Tools (To Enable Non-Market Installs, and re-enable ADB)
Installs Calendar and Calculator.
Installs Android Market, Gmail, Youtube
Installs Gingerbread Keyboard
Enable ADB
Enable Multi-touch for Android Apps
Enables Live Wallpapers
Enables Android Market and Gmail.
App Auto Install (Open up NooterFiles from sdcard drop in /data/app)
Known Problems:
With the version 1.1 update, ADB will not stay active after a reboot or unplug of the cable. To enable each time you want to use it, you will have to go into NookColor Tools /All Settings/Development/USB debugging, you will have to uncheck the box and then recheck it.
How to Use:
Before you begin:
* To update to 1.1 you must do a complete wipe.
* You must update to 1.1 to use Auto-Nooter 3.0.0 Instructions HERE.
1 You must already have a registered NOOKcolor
2 You must have a Gmail/Youtube linked Account. IF you used a Gmail account for B&N Registration you should use that one for this process.
3 You must either have dd (Linux) or WinImage (Windows) software.
4 You must have an external microSDCard reader or this will not work. Do NOT use the NC.
5 You must have enough intelligence to follow instructions.
Let's get started:
1 Download Auto-Nooter from here: MultiUpload or MediaFire
*MD5 FB74865663B8D797A486A85022FAD9B2*
2 Linux: Unzip and use dd if=auto-nooter-3.0.0.img of=/dev/sdcard
2 Windows: Unzip and use WinImage to "Restore Virtual Hard Disk Image" to your SDcard.
2 Windows Alternative: https://launchpad.net/win32-image-writer/+download
3 Unplug your NOOKcolor from computer. (If Plugged in.)
4 Insert AutoNooter SDcard into your NOOKcolor.
5 Plug the USB cable into your computer and your NOOKcolor. (This will boot up the NOOKcolor.)
6 Your NookColor will reboot when it's done.
That was the hard part, now to the simple stuff.
7 Upon boot unlock your screen.
8 At the Android Welcome Screen skip Sign In.
9 Enable Location Services when given the option.
10 Connect to Wifi and launch Youtube from "Extras".
11 Click the Menu button (The one RIGHT of the Up Arrow).
12 Select "My Channel" and Login using your Gmail Account.
13 Exit Youtube and Launch Gmail from "Extras".
14 Sync your Gmail Account and Exit. (If it fails to sync that is fine.)
15 Open up Market and Accept Terms and Service.
If you made it this far your nook should be successfully Rooted. Go Download an App to make sure.
16 Enable Non-Market Installs by running the NookColor Tools App.
17 If your Youtube fails to launch, download the attached EVO HQ, and follow this code in adb
Code:
adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
adb uninstall com.google.android.youtube
adb push YouTube.apk /system/app
adb reboot
18 Go to Settings > Device Info > SdCard > UnMount > Format
Complete Wipe:
1 8 Failed Boots > Wipes /system
2 Factory ResetFactory Reset > Wipes /data
*You must do both of these to completely wipe clean your NOOKcolor.*
*Before anyone starts to say that I took this project away from GabrialDestruir, I posted this file in the original post, and sent the OP a PM asking to update the current project. I have yet to hear back, and the post was not updated. My post can be found HERE, dated February 2, 2011. I felt that this would be of a benefit to the community, so I am posting it now. If I am asked at some point to take it down I will do so at that time.*
Forgive my ignorance here, but I thought you were never supposed to use the NC to format your SD card? (last step)
I thought I read somewhere that it messes up something in the emmc?
Hopefully I'm wrong and just paranoid

I have never really seen an explanation as to why you don't format on the NC. I have formated via the NC and the card works fine both in the NC and my PC. When I want to burn an image, I have been able too. Been able to flash other images on it too.
Excellent!
Can you please add an MD5 to the first post?

Formatting the SDcard doesn't touch the onboard storage. It is one of the easier ways to remove bonus partitions to recover the full card. UPDATE: I should clarify this: when running Eclair internally.

You're thinking of Nookie Froyo. The stock B&N system is fine for formatting the card.
I think formatting the SD card is an issue when you use one of the Froyo images and boot from eMMC. When you format the SD card it actually formats the internal boot partition or some such. I remember reading it in one of the threads which led me to only boot the Froyo images from an external card.
I am at 1.1.0. When did 1.1.1 appear & how do I get it?
BTW Is this exactly the same as the interim A-N 2.12.25 modified for 1.1?

I'd say it's a typo and should be v1.1?

also interested to know that!
And if there is benefits, can we use the auto nooter?
Just for clarification, in steps 3 & 4 should the NC be turned off? I have never been sure if it matters, but the following statement makes me think that it should be off,
"5 Plug the USB cable into your computer and your NOOKcolor. (This will boot up the NOOKcolor.)"
Thanks,

I guess it should be the same, but I had a couple of games break after up'ing with 1.1_r2. So I wanted to try stock/clean 1.1 and then root...hoping this would bring them back.
help please
I'm having a problem rooting my nook color. 2 weeks ago I was fully rooted and for some reason I forget why? but I went back to stock. recently I updated to the newest Barnes & noble firmware. seeing the recent developments of honeycomb I wanted to root my nook again. so I tried downgrading to firmware before the most recent update and using that version of auto nooter. I followed the instructions exactly to a tee. the problem is my nook wont load the disk image from the sd card. I made sure to fully format the sd card before writing the img with Win32DiskImager. I made sure the nook was completely off then plugging in the usb to into the pc to wake up the nook. but nothing? the nook boots up like normal then says sd card damaged. I've formatted the sd card again and have used the newest nooter for my current 1.1. but nothing. the only difference is the first time I rooted I was at my mothers and used her pc. it was a windows vista 64 bit. my computer is windows seven 64 bit. anyone have any idea's as to why the nook wont load the sd card with the nooter image? I'm using the same sd card I was able to root from before. so I seriously doubt its the sd card. I am properly formatting it before writing the img. I am having no problem writing the img. any help would be appreciated

You probably have a bad burn on the sdcard. Are you writing to the sdcard from the sd card reader or from the nook? Also, if you return to stock, (8 failed boots, then Power+N) You should be on firmware 1.0.0 or 1.0.1. Then root using one of the two original auto nooters, download rom manager from the market and flash the 1.1 pre-rooted firmware.
Thanks buddy, I try doing that. and I don't have an sd card reader so I just put the sd card that I'm going to write into my cell phone. then mount the sd card and write the img to the same storage device that represents the sd card. I'm sure this is the wrong way of doing it but I have gotten root doing the same thing before
Giving this a go now, coming from auto-nootered 1.0.1.
I've got the Telstra RHOD110 and I've tried to install every Android build since about the first stable Froyo release. Every single one of them hangs during the Linux boot sequence.
It seems to be memory related, but past that I've got no clue - I'm an IT professional, but I'm in operations, not development so I'm a little out of my depth with this stuff.
I have NOT done HardSPL yet, but I was under the impression this wasn't necessary for the SD card method (which I wanted to test out before potentially bricking a ~$1000 phone). In theory it's just the standard Telstra WinMo 6.5 ROM...
It's getting a bit frustrating after years of trying this and seeing everyone else talking about how easy it is. I'm using F22's rootfs and TotalCommander isn't showing up any *.csv files in the \windows directory, so I can't even try the GBX0C (2.3.7) test build. Anyone know why my phone seems to be different?
Hi Nukkels lets focus on getting GBX0C running since

First things first: Format the MicroSD you plan to use using the HP USB Disk Storage Format Tool. Just use google to find it. I use version 2.1.8. Perform a FULL format, FAT32.
Now download the package from here: http://files.xdandroid.com/GBX0C_Full_Bundle_2012.04.24.zip and extract all of the files to the root of your SD card

This device is identical to the RHOD100_UK so pull the startup.txt out of the STARTUPS\RHOD\RHOD100\ and place it on the root of your storage card.

I think I understand why you are trying to use that rootfs since it has some stuff tailor made for Rhod110/Telstra but I don't think it is necessary. Just leave the existing rootfs.img from the GBX0C package, it should work for you.
Nukkels said:

I haven't used TotalCommander for a while, but it seems to me that there is an option like "Hide Files in ROM" or "Show Hidden Files" or something like that which is probably preventing you from seeing the .csv's in /Windows/. So find that option and find those files and copy them to the root of your storage card.
If you can't find them I think that GBX0C should still boot as I have booted without any .csv's, there was just no sound in the build. But at least you can see that it is working. In case you absolutely cannot find them, here are my .csv's from rhod100uk: View attachment RHOD100_CSV.zip, unzip to your storage card, which hopefully will get you going.
Okay, now all you need is a touch screen calibration file. If you do not have one here is mine:View attachment ts-calibration.zip
Unzip it to the storage card.
Now you have everything in place on the card, please at this point do not try to edit the startup.txt or anything in /conf/. Lets just get this baby working.
Before you run anything I would set WM to airplane mode, set your backlight control to any level but auto (ie low), and make sure that you are not overclocking your processor in WM.
Now run HaRET.exe from the root of the storage card and cross your fingers mate!
Be patient, first boot can take ~10 minutes sometimes.
EDIT: Also there is a fairly good chance that your thread will get moved to the Android section... if it does and you aren't able to post in it anymore you can PM me.
I just wrote up a huge post and lost it all :crying:
Basically I followed your sintructions step by step and it worked!
I'd never done a FULL format before - that takes hours! I'm guessing this might have been the main issue.
I'll play around over the next few days with F22s rootfs and rhod110 startup parameter, Airplane mode turned on, etc to see if any of that had an impact. I never thought to set backlight to manual or use Airplane mode.
Hopefully I can help find the crucial step I missed, so it can be included in the installation instructions (or at the very least someone might stumble on this thread).
Anyway thanks a tonne for your help, it got me up and running!:good:
Thread moved to the appropriate section.
I genuinely hope you didn't pay ~$1000 for this phone... wow.

Did you bite your tounge just right while dancing backwards to the wizard of OZ soundtrack? That always does it for me when it 'wouldnt work'.
My experience was that the full format using the HP tool is a crucial step. I did a full format using other tools but I had no joy until I did it with the HP tool.
I am now making post that there really shouldn't be any need for, because all that's in here is already covered elsewhere. 100% Apparently not easy enough to find for newcomers, so I'm making an attempt to help info collection.
NOTHING here is my work! All I’ve done is trying to make easy to follow instructions to other people’s hard work. Those people deserve your thanks, not me!
I’m a newbie myself and that’s why I can say that this really is very easy! If I can do it without problems, so can you! I try not to chat away too much in the instructions. Make regular searches, here or Google for more info. I found it, so surely you can too! Any questions? Well, being a noob myself I probably can't answer. Google is a very good friend of mine though...
Please do not ask questions through pm. It's better if people that know more than I do get a chance to answer them in the thread instead!
You need to know how to burn an sd image. Separate instructions to that after the other instructions if you don’t.
Step 1: Establish what it is you want to do! Choose A, B or C
A: You do not want to touch the internals of your NT but want to try CM10 anyway
B: You want to stay in the BN environment but would like to be able to install apps from elsewhere (for example Google Play Store)
C: You want to get rid of BN and install CM10 instead.
A: Run CM10 from sd card – no root required
This should work on 8GB Tablet as well as 16GB
When you boot into the card you’re running Android ICS. Remove the card and you’ll boot to internal BN operating system. (Or keep the card in, boot to Cyanoboot Menu and choose “internal boot”)
Ready-made card image download links to be found here: http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/
It’s a large download (around 500 MB), but it is a ready-made sd card image. As it says in the instructions there, you’ll more than likely want to expand the user partition to take full advantage of the card, but that’s covered in his instructions.
There are other, more manual ways to make these cards as well. Also covered both in that blog and here at XDA! Go search!
B: Root the Tablet
This works on both 8GB and 16 GB Tablet.
“Rooting” is like unlocking your device, giving you access and control over it. You’re still running BN operating system though. Several excellent root guides here on XDA.
For example: http://forum.xda-developers.com/showthread.php?t=1488035
Or http://forum.xda-developers.com/showthread.php?p=21275927#post21275927
The first one (Brian’s) require a 2 GB card the other one (Albert’s) just needs a very small card. (I think 128 MB would do, but I don’t have any that small to try)
Both give good instructions in their topics.
Both install gApps.
If you want to block OTA updates from BN, go to Play Store and find NT Hidden Settings. Even if it got installed with the root it’s probably not latest version and doesn’t have the Block OTA function.
C: Installing CM10 internally
***8GB owners must make sure to use ROM that works with their device!***
Since I’m a noob I look for easy way, and this is very easy and needs very little know-how!
***Warning! CWM is a very powerful tool. Do not "wander around" and "experiment" with stuff without doing proper research! Seriously! DON'T!***
1. You need a bootable CWM card. Instead of making my own I use Albert's root image from B (above) because this image includes CWM 5.x.x. I use this to flash a higher version CWM internally. I erase the zip files from the card to make room for a flashable CWM 6.x.x
2. Find a flashable CWM 6.x.x I found mine through http://forum.xda-developers.com/showthread.php?t=1640958
I use the one named "flash_cm9-10_cwm v6...." Download and copy to your sd card.
3. Boot into the sd-card and it should take you to CWM 5.x.x. environment.
I guess a backup of you current system would be a good thing (even though I admit to skipping that myself). To backup you'll probably need another card if you're using "The Albert Card" now, because I doubt it's enough room on that.
You navigate with the volume rocker, go back to previous menu with “power” and confirm choices with “n”
Choose “install zip from card” – “choose zip from card” – your CWM zip
See warning above!
4. Power off and prepare your sd card for ROM flashing. (If you’re working with just one card you will need to format it with SD Format or similar to get it back to full capacity.) Put your CM10 ROM zip and the appropriate gApps zip on the card.( It doesn’t matter if there’s other stuff on the card, so you don’t have to format it because of that!). I will not link to a specific ROM. Make your own choice but be sure it works for your model and also make sure you use the right gApps!
5. Reboot into Cyanoboot. This took me a couple of attempts to get right.
From powered down device, press power and right after that press and hold "n", You should boot into Cyanoboot and get the boot menu. Choose "Internal recovery" and you should get into new CWM
6. I don’t know how much clearing is needed, but I prefer to clear pretty much everything to make sure of a clean install. Cache and Dalvik I always clear.
***DO NOT format anything unless you knwo what you're doing! *** (See Satan's posts below)
7. Flash ROM and gApps same way as you flashed the CWM 6.x.x (install zip from card – choose zip from card) reboot and go!
How to burn an sd-image:
I use Win32Diskimager. Download link in Albert’s root topic (and numerous other places!!)
Unzip into a folder.
(I also copy my various img files to that folder to have them easily available)
No need to install, just run by doubleclicking the EXE in the folder.
Make sure the device letter really is your sd card.
Click on the blue folder and navigate to your img file, choose it and “write”.
It will take some time if it’s a large img, but that’s what the progress bar is there for, isn’t it?!
Nice work ,
But you should add 'do not format any partition ' warning. Android users coming from other devices might do this by default during flashing rom.
Almost every one with bricked tablets has tried formatting partitions.

Do not format especially the rom partition and, most critically, the factory partition which respectively contain a set of small files with device-specific unique data (not only Serial No. but also MAC address, public/private key certificates, etc.) and the backup archive copy of the same data files (/factory/romdata.zip).
Unfortunately, I've seen some "unbricking" tools (including some that are very frequently cited/recommended on these NT forums) reformat/zero-out and flash over these 2 partitions. The end result being, even in the event the "bricked" NT gets "restored to stock", depending on the specific tool used it could be carrying device-specific data of someone else's (e.g., tool developer's) NT.
EXACTLY!

Help
Im trying to single boot CM10 from sd card without touching nook os. I am using guide (CM10.0 Jellybean SDCard IMG for Nook Tablet (12/31) FINAL)
I have tried for hours using different methods also and cant even get it to boot to CM, no CM logo at all. I have a BNTV250 NT on 1.4.3. I have tried multiple sd cards, I am using a Sandisk 8gb class 6.
In a nutshell all I should have to do is
-Format the card with SD formatter,
-Extract the (Extract cm10_xxxxxx_sd_hd.img from cm10_xxxxxx_sd_hd.7z/rar)
-Use Winimage to write the image to the SD card, correct??
The Nook still refuses to boot into Cyanogen, just boots up normal every time!
same with every procedure i have tried,
Any pointers????
Have you tried putting the sd-catd in the powered down Tablet and then insert the charger cable, connected to the charger?
Many Tablets have difficulties booting into sd other ways,

I've never had to do it that way myself so I really don't know. You could try pressing the "n" buttons right after the power button and holding it for a few seconds.
Actually not being able to boot into SD card easily is the reason some install internally instead.

Alright, just got cwm 6.x installed and now ready to install rom, just wanting to verify that I should still "wipe data/factory reset" and "wipe cache partition"? That is different from "formatting" correct? I don't wanna brick this thing without confirmation. Thanks for the awesome guide!

Hi everyone,
Just bought a used NT and I flashed cm10.1 and TWRP 2.8.4.0. After a reboot, my NT shows a pixel glitch screen after the N logo then stucks at it. I tried to press power button to hard reboot, but it doesn't change. A recovery sdcard doesn't work to it too.
So I'm here to ask if there's any way can rescue my NT. Thanks.

You need to find a way to either power down or at least reboot (after that you need to remake your flashing file sdcard because there is clearly something wrong there).
Of course, you could let the battery die on its own, then boot up an sd recovery card. That will return your device to FW 1.4.2 and fix any partition issues.
So unless you can force a shutdown or reboot with the power button, you may not have many options other than to drain the battery (or open the device and disconnect the battery for a minute).
Edit: Also, that TWRP version looks way out of range for CM 10.1 Should be more something like 2.2.2. A newer TWRP version may not work at all with an older ROM like 10.1 (why 10.1, and not 11, or 12.1, or....?)

Thank you for your reply.
Maybe it's not clear that I explained about the reboot (sorry for my bad English, not a native speaker), I can press the power button to shut it down, or hard reboot it. The problem is that the glitch screen shows every time and stucks every time.
May I ask that how to use the sd recovery card you provide? Shut down, insert the sd card, boot up and follow the instructions, is that right?
About the TWRP, I was tried to flash lineage 14.1 to my NT but the latest version of TWRP (3.1.1.0) doesn't work on my tablet, it's just black and blank after I flashed the recovery, so I have to use the older version. Besides that, some versions of TWRP has the famous error that both internal storage and micro sd card are 0 mb size. That's strange. Because I download them all from the official site.

First, yes, you insert the recovery card, boot the tablet and follow the screen instructions, mostly "are you sure?", etc. This will restore your tablet to factory condition, FW 1.4.2. Should work for either 8 or 16 GB models.
Secondly, I hope you do not really mean CM 14.1. That would be a mistake, I think. That ROM requires repartitioning and there are newer (possibly better) options that do not.
If you are set on Android 7, then I suggest either AOSP 7.0 (which is what I run on my tablet) or LNOS 14.1 (which I have only tested on an 8 GB model, so I can't give a fair assessment:

If you have trouble with the TWRP from the actual website, let me know and I'll post a copy of my file. The emmc TWRP 3.0.2-0 is a little squirrely. The touch interface is shaky and you have to look carefully at what you have selected (or deselected) before going on to another step or you can end up in trouble. Not my favorite version.
Root, etc. for each of the ROMs is achieved a little differently, so when you get to that point, ask.
I don't recommend adding GApps to these unless you absolutely must have it. I do have GApps installed on my AOSP 7.0 install and it's "OK", but it would be more responsive without it. If you must have Google access then microG is probably the better way to go. You can read more about in my post on the 8 GB tablet. Everything there is applicable to the 16 GB tablet, except the ROMs I reviewed would all be expected to perform much better on the 16 GB version.

Some tablets will not boot from the sdcard unless they are plugged in to external power (either the power pack or USB from your PC). Try shutting down, then insert the power cord to make the tablet boot (it should come on by itself when power is applied). See if that helps.
OK, I should have given a lot more instructions with that file but I have never used it myself and forgot about all the stuff.

You may need to try another card, if you can get one. This is often the problem when the tablet won't boot (did you try booting by inserting the power cord?). It may take some trial and error, and as they say in the instructions, you may need to remake the card (reformat, re-write the image) to get it all to work.
I can't think of any other approach for where you are now. The device clearly can't get to either a recovery or an OS.
With no SD card in, does it show up as some sort of USB device? Maybe 0451/d00f?

Well, that means that there is *something* there.
Go to Device Manager and look for something with an exclamation.
Go to Details and look for Instance path.
I'm not sure even with an external SD card whether it still relies on the loader in eMMC.
OTOH, it could be a case of your regular system working well enough to start (and not go to SD) but too screwed up to run.

I checked the device manager and found nothing. Literally, nothing there even after the weird announcement popped up.
I agree with your idea: maybe my emmc and system work fine, but something of bootloader or hardware has some problem so I got a pixel glitch screen. In my observation, the pixel glitch scrolls out from the right margin of the screen and covers the n logo and adobe claim. I still can recognize the text and images from those pixel snows, so I highly doubt that something about rendering must be wrong.

What you describe is "normal" for a NT booting Cyanoboot--up to a point. With a properly functioning card, first boot copies over the cyanobootloader so that subsequent boots are from the emmc (assuming the system is intact). On the 16 GB NT every boot from the powered-down state flashes the pixelated screen briefly, and all at once. On the 8 GB NT, the pixelated effect moves from one side of the screen to the center and then from there to the other side until the entire screen is covered, then boot continues. and the pixelated effect disappears.
The problem seems to be getting a boot from the sdcard. If you read through the now crippled forum, you will see that's not so uncommon. The most common solution is a different card or at least a complete re-write of the offending card.
It has been reported often that some NTs cannot boot from the sdcard unless they are connected to a power source (either the charging pack or the USB connection to a PC). I have not seen this with my two tablets, but it would not surprise me.
Even making the original cyanoboot sdcard is filled with traps. Everything has to be done just right or the card will fail to boot or--worse--wreak havoc on the system.
It occurs to me that one other approach to this situation is to prepare such a card as if you were going to flash a custom recovery and a ROM. These instruction shepherd you through the card preparation:
nmyshkin said:
1. Using a disk partition tool (such as MiniTool Partition Wizard Home Edition) create on the SD card a Primary FAT32 partition, set the partition ID type for the partition to 0x0C FAT32 LBA, and set its Active flag. Once this is done, the partition should appear as a (read/write accessible) drive under Windows
2. Obtain and copy to the SD card the following files:
a. first MLO, then next u-boot.bin, and finally flashing_boot.img in succulent_boot.zip obtained from https://www.mediafire.com/folder/xjwc1a482a6ll/Nook_Tablet
b. TWRP (TeamWin Recovery Project) version 2.8.6.0, e.g. twrp-2.8.6.0-acclaim-sdcard.img from https://dl.twrp.me/acclaim/twrp-2.8.6.0-acclaim-sdcard.img.html, rename it to recovery.img before copying to SD card. Be sure to use the sdcard.img file and not the one for internal emmc
c. the flashable_TWRP_3.0.2-0.zip zip file from https://www.mediafire.com/folder/xjwc1a482a6ll/Nook_Tablet
Click to expand...
Click to collapse
Every single step is important, especially step 1. In step 2a the order in which the files are placed on the card seems to be important according to some guides. So every detail is important. No shortcuts. If you can prepare such a card and get your device to boot from it (try with the power cord), into the Cyanoboot menu, you should be able to flash a good emmc recovery and then......a ROM. But if the card won't boot, you can't do any of that.
Edit: Does this work on your tablet, or is it too far gone?
Perform Factory Reset of the Nook Tablet:
PWR off the Nook Tablet.
Hold "PWR" & "∩" & "VOL+" & "VOL-" buttons simultaneously to reboot.
After reboot, release only the "PWR" & "∩" buttons after 2-3 seconds upon receiving the "∩ - Contains Reader® Mobile technology by Adobe Systems Incorporated." screen while still maintaining to hold the "VOL+" & "VOL-" buttons.
The screen may blink a couple seconds later and then you will be presented with the Factory Reset screen with the following options:
Do you want to reset your device to the factory default?
Press POWER key to exit
Press HOME key to continue
Are you sure?
This will delete all your content and restore the device to the factory default settings.
Press POWER key to exit
Press HOME key to continue
I even accidentally let go of the "VOL+" & "VOL-" buttons once while testing this a few times but quickly pushed them back down again and was still given the factory reset screen so this method works even with a little goof like that. This worked since holding down the "VOL+" & "VOL-" buttons was found to be unnecessary.

What you describe is "normal" for a NT booting Cyanoboot--up to a point. With a properly functioning card, first boot copies over the cyanobootloader so that subsequent boots are from the emmc (assuming the system is intact). On the 16 GB NT every boot from the powered-down state flashes the pixelated screen briefly, and all at once. On the 8 GB NT, the pixelated effect moves from one side of the screen to the center and then from there to the other side until the entire screen is covered, then boot continues. and the pixelated effect disappears....

It's just so weird.... I booted it successfully and my NT works well again.
I made a new recovery card, here's what I did:
1. Format a 8GB Kingston card to FAT32, set partition ID type to 0x0C FAT32 LBA, then set it to main active partition;
2. Copy everything for the card (MLO, u-boot.bin, flashing-boot.img, renamed TWRP 2.8.6.0-sdcard, flashable_TWRP_3.0.2-0.zip) to the card;
3. Plug my NT to PC, insert the card, boot;
4. Pixelated screen disappears and it boots normally to the sd card cyanoboot;
5. I entered to the sd recovery and flash the 3.0.2.0 TWRP, reboot.
Now it's running but I still have some problems.
First, when I try to perform a factory reset in the sd recovery, I noticed it has a caution that "Unable to mount /bootdata/," I'm not familiar with the system structure but I think ihat where the boot files save and maybe it caused the pixel glitch;
Second, when I check the partition status in new flashed TWRP 3.0.2.0 on emmc, It doesn't show any partition except ART / Davlik Cahce in Advanced Wipe page. I'm not sure what's going here. Then I rebooted to system, which works fine, and reboot again to recovery, and all partitons come back.
I'm so confused by all these things but at least I can use it now. May I ask, if I want to flash the AOSP 7 ROM, whcih version of TWRP I need? Should I flash it with sd recovery or emmc one?

The emmc version of TWRP (3.0.2.0) is full of little goofy "error" messages. Just ignore the bootdata messages. In general, TWRP is not going to wipe out /bootdata/ unless you try really hard. That's to prevent you from ending up with a brick.

This I cannot explain, but I hope that things will settle down as you begin flashing a ROM. Just bear in mind that the emmc TWRP has a poor touch interface. Always be sure items you have checked (or unchecked) are really that way. There should be no highlighting around a checked or unchecked item. If there is, it's not really what it looks like and you need to select (or deselect) again until you have a normal checkbox.

The emmc TWRP you have is the correct one for AOSP 7. Continue here: https://forum.xda-developers.com/t/...-internally-on-the-16-gb-nook-tablet.3578665/ with step 2d. I do not recommend GApps, but it's in the instructions. If you want it, here is a link to the package I used. All the packages at OpenGApps seem to auto-expand with time until they are too large for our devices. If you don't want GApps, just skip any steps that refer to it.
Then proceed to step 3d since you have already flashed the emmc TWRP.
If you want full root access you'll need the superuser control apk. Here is a link.
I know the instructions are very tedious, with a lot of rebooting, but they are what worked for me reliably, over and over again. Detail counts in this kind of thing (and luck!).

It was the card, yes.
A brand new new questions here:
When sd card is inserted, I can't reboot or reboot normally or to the recovery. I did it from the power menu then it gives me a black and blank screen until I hold the power button to force it shut. If I try to boot it from the shutdown status. I have to remove the sdcard otherwise it can't be booted.

I'm not sure I understand, but the sdcard you have made is not something that you would normally leave in the device. It is for flashing purposes only or for accessing the sd-recovery for some reason (like the emmc recovery gets messed up somehow or you need to flash something that is too new/too old for the emmc recovery).
If you completed the initial cyanoboot installation corrrectly, the device should boot into cyanoboot and then to the ROM (if installed) when turned on (without the card). If you leave the sdcard in and power up without selecting the "n" button to get to the boot menu, you will get an error about "boot magic", etc., and the device will just sit there on the cyanoboot screen.
So, yes (?) you need to remove the card to boot "normally" (i.e., into the ROM), although even there if you are quick you can intercept the boot with the "n" button and go into emmc recovery (from one of the boot menu options).
Is the problem that you don't have any OS? I wasn't clear whether that survived your first attempts with the bad card.
Edit: if you want to use an sdcard with the NT for storage it will have to be a different one than the one you prepared specially for flashing cyanoboot, etc.

I restored the ID type of the sd card and now my NT can boot normally with the card inserted.
Tried the AOSP 7 you recommend and it's very good, thank you for it - but I think it would be better to have more custom settings, but Xposed and something like that are too heavy to NT with AOSP 7.
I tried to flash the lineage os 14.1 in your notredame folder but it can't boot. Looped at booting animation. Also, I tried a rom from AndroidFileHost, DrM-14.1-acclaim-Root-OC, but I got the status 7 error when flashing it, nomatter I use 3.0.2.0 TWRP on emmc or 2.8.4.0 one on the sd card. Any suggestion?
