Emergency help for NT, booting glitch - Barnes & Noble Nook Tablet

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:

(there are many versions of this ROM. The link takes you to the "obsolete" folder where you need to hunt down lnos_acclaim-ota-NJH47F.180211.zip. This seems to be the only version without the shut-down bug)
Flashed with emmc-based TWRP 3.0.2-0

For either of those ROMs you can use the sdcard version of TWRP:

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

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.

Thank you for these detailed instructions. Unfortunately, I write the factory reset file to a 16gb sd card, insert my NT and boot it, nothing change.

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. Here is a link (messy...the important stuff runs down the left side of the screen) that describes how to use that zip file to restore your tablet: https://web.archive.org/web/2018082...06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/

I hate to say this but it doesn't work, still can't boot from sd card. The interesting thing is, my NT will automatically reboot after stuck at glitch screen for a while.

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?
"doof" is German for stupid.

Unfortunately no. It has no reaction on mac and when I plug it to PC, windows shows me a announcement that there's a device which doesn't work properly

That's weird. I followed the instructions on that page but still doesn't work. everytime I boot up, I got a quick N logo show screen then the familiar pixel glitch one.
Also I tried to change the partition ID to 0x0E FAT 16 LBA according from a thread in Chinese forum, but nothing changes
I was wondering if it's any kind of hardware issues?

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...

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.

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?

Cannot Install gapps on bootable MicroSD Card (CM7)

I am trying to install Gapps on a bootable MicroSD card to run on my Nook Tablet BNTV250 16gb running the BN 1.4.3 software version.
I have successfully booted CM7 in multiple separate attempts (whereby I completely blow away and reformat and re-burn the SDcard in between attempts).
I am using Wind32DiskImager for writing, and diskpart to blow away and reformat the card in between attempts.
Team-B-CM7SD-Alpha_final.img
gapps-gb-20110828-signed
I am using a PNY 16 gb class 10 micro SD card.
My goal is to get Gapps working. its the last step to truly get the device's functionality significantly beyond the stock functionality of the Nook.
I have, thus far, been completely unable to get it working.
I have noticed at least a few discrepancies between what my software displays and what has been described in some of the guides I have been following. I am NOT yet set to root my device, and I am trying to keep it to the bootable card for the moment.
I have tried the following methods all without success:
1) install (copy) the gapps Zip file to the root directory and "reboot in recovery mode" using ROM manager
-- this didnt work because the reboot process resulted in the Nook Tablet booting the stock OS, and it gave me the stock error message
-- Yes. I booted CM7 first, enabled Wifi (and my Google account in several attempts), turned the device completely off, removed the SD card, copied the Zip file, turned device completely on, then attempted the reboot procedure.
2) install (copy) the gapps Zip file to the root directory and "reboot in recovery mode" by pressing the power button, then choosing reboot, then choosing "reboot in recovery mode"
-- this didnt work because, for some reason, I do not get the option to "reboot in recovery mode." If I choose "reboot" from the power-button option list, the 2nd window that popups merely says "reboot" with a green circle opposite and "OK" or "Cancel" as the only text in the window
3) "hard booting" into recovery mode by performing the procedure that involves holding the power button and the N button in sequences...
-- this didnt work because I never even saw a loading screen even once. If I press and hold the power button while holding the N key (press the N-key FIRST), It just loads that first CM7 screen, then black, then the loadout with the circle/arrow splash.
no loading screen of any kind.
4) The "Multi boot" method that uses a separate U-Boot.bin file. I tried multiple different U-boot.order files ("10" and "01") but none worked.
-- the reason that this did not work is that as soon as I replaced the u-boot.bin file, it made it so that my Nook would no longer boot up at all.
this is a repeatable bug that only manifested itself after replacing that file.
I hate to say it, but I am completely stuck.
yes. i have spent HOURS reading through posts. unfortunately this forum is cluttered with guides and step-by-step methods and "fixes" that have helped SOME PEOPLE, and you could spend weeks reading through the first 5 relevant search results before you find a solution.
I am by no means new to modding or homebrew consumer electronics stuff. However, this is my first forray into the Android homebrew scene.
I would not be surprised if the solution existed somewhere on the forums. As I am sure everyone understands, there are many situations where the solution may be difficult to find despite it being a common issue.
Please don't respond with a link to another thread. Chances are I have seen the thread. If there are specific points associated with the thread please TELL ME. if it takes you 3 seconds to paste a link, i seriuosly doubt it would take you more than 20 or 30 seconds to type a full response.
I'm going to be completely honest in saying I didn't read your entire post.
But what I know for sure is that gApps are already pre-installed to the CM7 SD ROM.

[HOW TO] Root/Run from sd/Install CM10

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.

Tried doping that with no luck. After 8 or 10 attempts magically boots todo cm. Thanks.

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!
edit: Ignore the wipe question, found it, thank again for the guide, I will let you know how the install goes!

[Q] Stuck on cyanoboot bootloader screen

So I have tried everything getting this thing (Nook 16GB Tablet) to work (boot off SD [class 4 8gb Sandisk] card into CM10.X+)
I have followed the directions to a T (several several times) and everytime I turn on my Nook it goes to the cyanoboot screen and goes to (SDC) LOADING BOOT and is stuck there, or if I hold the N before it get to it it will allow me to choose my boot option (I've tried the SDC recovery to use automatic partition zip provided on iamafanof's wordpress site; please note I have tried it with manually partitioning, and just leaving image as is and same results).
I have did a complete factory restore via the repart.img method, tried different SDC image versions, bought a new SD card just to make sure it wasn't the card.
The weird thing is I can create a CM7 SD card and it loads fine (so I don't think its the SD Card).
I am at witts end with this; I work in technology as a career (on a bit diff side) and this thing is driving me nuts not working.
I have tried booting tethered as well; the only thing that may be different is that I bought this used and it has an aftermarked (Griffin) charger.
What really sucks was I was originally thought I bought a NC b/c I heard it was easier to create a bootable SDC and found out I had a microphone
Can someone recommend a next approach? The only other thing I could think of was to try the alt boot files on "iamafanof" wordpress site but the links are dead.
I don't care if its 10.1 or 10; just really interested in Android 4.0 period.
Also this Nook was 1.4.3 when I first tried to boot from SD; since then I went through process above and now is 1.4.0 factory reset.
I have looked through the forums EVERYWHERE and I decided to join here to get help - thanks in advance!
I hdon't know why this happens, but just to be clear, have you tried Iamafanof's ready-made CM10 bootbale sd? http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/
If you decide to install CM10 internally this image can be used as a bootable CWM card even if you don't want to run CM10 from it.
And FWIW, why does it suck that you got a Tablet instead of a NC? The Tablet is so much better, and certainly not any harder to mod.

Well guess it doesn't suck considering I payed 50 for a better tablet, I am just annoyed with it at this point. Yes I did, I formatted a SDC and burned that image to it after unzipping ( cm-10-20121231-NOOKTABLET-acclaim-HD-SDC-img.rar ) as well as other versions and they don't work even if I don't mess with partition tables. My only guess is that the boot files in the boot 1st partition of the image aren't compatible with my device which could be explained since I'm sure mine is a late model ( but why does CW7 work ? )
At this point I wonder if its possible to use the CW7 SDC and just copy gapps and the 10.1 Rom over. I'm extremely new at this so hopefully that isn't a stupid idea.
I do want to stay away from rooting internal for various reasons.
Any ideas ?

I'd suggest you try flashing flash_kernel_acclaim_30MAR2013_HD_SDC.zip at http://iamafanof.wordpress.com/2013/02/18/cm10-1-jellybean-android-4-2-2-for-nook-tablet-0218/ (under heading "Flash this if your NT doesn’t boot newer kernel" in SDC section).

That's for if your doing the internal root though right ? I don't want to do that. I listed above one of the exact zip files I tried, I've tried several of them ( the pre done SDC images). And none of them will boot past cynogenmod .

Ok I now see it (flash_kernel_acclaim_30MAR2013_HD_SDC.zip) but how do I flash it if I can't boot into SDC Recovery from the Cynogenmod screen? Does it modify internal ROM - can I put it on a blank SD Card or on the CM7 and go into recovery?
Sorry if this is a noob question.
Well I've now tried it manually > forum.xda-developers.com/showthread.php?t=2098419
and I get stuck at the same place (booting into SDC Recovery in steps).
I have ruled out it being the SD card (unless I some how managed to get two bad ones that still boot into CM7).

Yes I did. I have another larger flash drive coming in the mail, I do not think its the flash drive though. No one else has ever had this issue? CM7 works fine, I may try to boot into CM9 later this weekend.
Just to clarify I have done manual method and burned image, they boot to the cynogenmod boot menu and if I pick SDC anything it just hangs there.
I almost want to say I don't think it's cynogenmod bc I can choose internal boot from it and it boots into nook fine

This so odd! It seams like there is something wrong woth the boot section on your sd, but I don't see how that could be the problem if indeed you have tried ready-made images that we know work for "everyone else"!

If you pick SDC Recovery from Cyanoboot menu it should say "loading SDC recovery" but it will take some time (up to between 1-2 min) before the CWM menu appears. Same thing with SDC Boot: it will take a bit of time before you see its boot animation. But neither should not take more than a couple of minutes to appear.
Also, for the manual method I'd suggest checking to make sure that boot.img and recovery.img on the SDcard /boot partition are not corrupted in the process of copying them to SDcard.

I am about 95% sure I have; I will try it again just to make sure; I tried several different versions of the image for 10.0 and 10.1 as well as the manual methods for both thinking it may be the build.
I will try to boot CM9.X and see if it works since 7 works. Really strange that no one else seems to have the issue.
In addition, I have left it well over 1-2 minutes at the cynogenmod screen and it never boots into CWM or the image (depending on boot option I pick).
So quick update.
I tried building a CM9 card and I got Cynogenmod to boot into SDC recovery (maybe I can use the same boot.img file?) However when trying to boot into SDC (after installing gapps.zip / ROM.zip) it reboots and boots into the normal INT nook.
Granite I may have messed something up with the process since I only did it once; but atleast I got past Cynogenmod screen.
Followed these directions and used these files:
http://iamafanof.wordpress.com/2012/11/11/how-to-guide-bootable-cm7cm9cm10-sdcard-for-nook-tablet/
ive had similar issues , one thing that hit me was that my downloads were incomplete . when you download the images of cm 10.X verify the file size vs the download page stated size and make sure that your downloads are complete. also i would try re downloading them all over again thats what i had to do , and follow the instructions to the dot but give us a link so we can see which ones your reading too , ive learned alot in the past three weeks of non stop hacking and modding on my tablet, its bricked itself three times so far and ive been forced to un brick it ,
the reason why i said that is , sometimes i get so worked up and over whelmed, take a five minuet break and go to the fridge and grab a drink and dont think about this for five minuets , clear your head and calm down then look back at the work you have already completed and examine it step by step fresh , you prob just missed one little detail ,
"it reboots and boots into the normal INT nook. "
if upon reboot it goes to nook , hold power button until its off , then hit power to turn it on , once N shows up hit the N button on the tablet if you have CWM installed to internal , this is like a short cut key to force it to boot to sdc , OR with tablet completely powered off plug in charger cable , it should turn tablet on ,and with cable inserted it should boot to sd card first , if it takes a while then goes to nook OS your sd card is incorrect ,
checked your link this isnt the one i used , i used this link
http://forum.xda-developers.com/showthread.php?t=2056626 yes its for 10.0 but once its installed internally you can connect to wifi and update to 10.1.2 4.2.2 in software on device , just remember to get the right Gapps before hand
forwarning , dont play with the touch screen firmware editor without reading , if you do pm me ill tell you how i crash coursed through that and how to fix it once you break that too lols 10 point is nice though
SD card version works nice too

[Q] [q] !!!!!!! I think i broke my nook tablet plz help

I POSTED EARLIER BUT IT NEVER SHOWED UP SO IM REPOSTING. sry for caps.
rooted my nook color and everything was fine. then i tried to root my nook tablet. searched all over the net for comprehensive instructions to do so and i found this
The first thing you need to do is extract the contents of file #1 and write the extracted img file to a Micro SD. If you are using Microsoft Windows then click the file named Win32DiskImager.exe, select the NT16or8gbV47SDimagefile.img, select your drive letter for your SD card.
If you are using Linux, then open up the terminal and CD into the directory where NT16or8gbV47SDimagefile.img is located. Once in the correct directory issue this command to write the .img to the Micro SD:
sudo dd if=NT16or8gbV47SDimagefile.img of=/dev/sdX
You must replace the X in sdX with the appropriate letter for your SD slot. There are many ways to get the correct letter but I use the program Gparted.
Ok, so now you have an SD card that will root your Nook Tablet. Let's boot into Recovey. Turn off your Nook if it is on, and connect the USB wire to your computer. Your Nook will now turn on and enter into ClockwordMod Recovery. Using the Volume Keys to move up and down and the N key to select, click on Install zip from SD. You will now see a zip file called Root_8gb-or-16gb-NTV4_7.zip. Highlight that file and press the N.
If all goes well, the operation will complete. You are now rooted. Press the Power button to go back to main Recovery menus and select Reboot and press the N key. Your Nook will appear normal. It is not. Press the N key and you will see a new option for Home screen. Clicking the new Home icon will take you to an Android looking desktop. Yay! We are not done yet.
Now, install ES File Explorer from the Play Store. Open the app and browse your Micro SD card. Look for a folder called Apps. In this folder you will see a file named Nook Recovery Flasher.apk. Click this file to install it. Once installed, click on Flash CWM Recovery. Now you do not need the SD card you made earlier to boot into Recovery. It is now part of the system.
Remove the SD card and connect it your computer and format it so that it is empty.
Copy the files #2, #3, and #4 that you downloaded from above to the SD card and insert it back into the Nook Tablet.
Remember how to boot your Nook into Recovery mode? Do it.
Select Install zip from SD again and install ONLY CWM_v6.2.7_emmc.zip. This will upgrade your recovery. Without upgrading, you will not be able to flash CyanogenMod. Once the operation is complete, use the power button go back to reboot the Nook. Boot it to Recovery one more time.
Now you can select the latest CyanogenMod file you downloaded to install it. After that, select the latest Gapps you downloaded. Reboot the Nook and you are good to go!!!
. i folowed all the instructions to the dot. but when i got the this step, "Remember how to boot your Nook into Recovery mode? Do it." and i did it. but when i rebooted it immediately tried to boot into recovery but got stuck on the cardboard box screen and it flickered none stop and would not proceed to recovery (CWM) menu. I tried everything i could think of and i found that if i reformatted my sd card with the CWM sd root img and put sd card into NT and boot up it successfully brings up CWM. from this i tried both normal cache wipe and advanced menu cache wipe and also tried wipe to factory settings and wipe battery stats, rebooted and it still gets stuck on the flickering cardboard box screen..........anyone have any ideas? i cant seem to boot it up at all past this screen. maybe i shud format system through sd-card cwm? but then i would have no OS, so how would i proceed with this. is it totally broke or wut? god i hope not:crying::crying::crying::crying::crying::crying:

well i think wut u gave me is exactly wut i need. followed the custom rom tutorial and it worked fine to the point to where i first get to cyanoboot menu where i would have proceded to install cm10 and gapps. but i accidentally put the wrong cwm on the sd card and it said bad boot. (note it also said it disabled charging) so i go the right cwm boot img for it. but the fact that it disabled my charger i cannot get back into the cyanboot menu. anyone kno how i can reactivate charging? if not then im completely screwed because once it dies i wont be able to charge it again and it will be flippin useless. even worse than before.........sigh fml someone shoot me in the dome
The "charging disabled" message on the Cyanoboot screen does not mean what you think it means (i.e., charging is turned off on for good until you somehow turn it on again). If you're stuck on that boot screen, just hold down power button for 20-30 sec to turn it off and start over with the SD card with the right CWM.
Yeah, I always wondered about why it says charging disabled when you are in the cyanoboot loader.
That being said, you should be just fine. I recently had to restore, then reflash, then restore my 16GB Nook Tablet. I saw that message in the upper left hand corner and all I really thought was, huh I wander why they do that.
As the poster above me said, just burn the correct version of CWM (you need v6 or higher), load your CM10 and Gapps .ZIP files onto the card.
When you see the Cyanoboot loader hold down the "n" button for the menu.
Select internal recovery.
Select install file from zip.
Select your CM10 .ZIP file.
Wait a few minutes while it does it's thing.
Repeat the same procedure from the install menu for the gapps.zip file.
Once it is done, you can safely remove the SD card. Sometimes this will make the Nook reboot. But that's fine. You want it to reboot anyway. It should boot into CM10. Sometimes the first boot can take a while as it set's itself up. Once it comes up you should be good to go.
Post back if you have any questions.
A piece of advice. If you ever for any reason may need to restore the Stock OS/ROM ***DO NOT*** run any 5point or 10point multitouch installer. If you do and you forget to reflash the multitouch firmware, you will be unable to use the touch screen with the stock OS. Then you will have to reload CM10, reflash the screen firmware, then reload the stock OS. I was running CM10 for months and totally forgot that I did the 10point flash. Screwed me over for a bit. Learn from my pain, don't do that. 99% of all Android users I know (and I know a lot, I work in IT) use 1 finger most of the time and sometimes 2 for pinch to zoom. So in my opinion, you don't gain very much functionality from it and if you forget to reflash the 2 point touch firmware, you could end up with a headache. Just thought i'd throw that out there.
YAY!

YAY! i figured out how to get past the bad boot part. just be sure to be vigilant and press "n" asap when the screen boots up in cyanoboot......and i mean like THE second it pops up. that solved all my problems.......
but i dont understand the piece of advice part with the 5 point/ 10 point touch installer deal. ill do alil research on it to see wut it is and wut i got to do. if you care to send a link explaining it that would be super flippin awesome. and btw thx sooooooooooooooooo much. this forum has been the most helpful place. quick responses and accurate information. everyone i talk to rocks. i appreciate it so much. :victory:
The 5point and 10point touch is just that.
So you know how your screen responds to your touch input? And let's say you use to fingers to zoom in on a picture. That would be an example of 2 touch. Expand from there for more finger interaction.
Here's an XDA thread on the topic:

and nice Wikipedia article on how multi-touch works:

Glad you are up and running.

[GUIDE] How to install Android on your Switch, step-by-step.

This guide was created for people who are not as familiar with the world of Switch exploits.
NOTE: This is not the official ROM thread! DO NOT ask questions about using, troubleshooting, etc. the ROM here. I will not be able to help you and it splits discussion. Please ask questions, tips, etc, in the official thread! This post is purely to guide users in setting up their PC and such for installing this on their Switch.
DISCLAIMER: Everything is done at your own risk. Use common sense.
What you will need:
An RCM exploitable Switch console. Check here to see if your device is exploitable. If you have a newer device an exploit may be possible on older firmwares, but if you haven't already set it up you probably updated to a too new version already. Read more here. (for non-RCM exploitable devices)
A jig or other method of triggering RCM. Here's a few methods. Premade jigs can be found online.
A computer. (Assuming a Windows PC for the purposes of this guide)
A good USB-C cable that can connect to your PC and Switch.
A high quality, high speed microSD card of at least 16GB.
A way to read microSD cards on your PC.
Required downloads:
The ROM, find it in the Downloads section of the first post. Select the SD Card size that matches yours. Read through the post as well for latest information.
If desired (but not required), the shield-ifier.zip and/or the Reboot2Payload zipfile also in the ROM downloads section. Shieldifier should allow you to download games meant for the NVIDIA Shield. Reboot2Payload means you'll reboot to Android when you hit "reboot" within Android (or Hekate if you choose reboot to bootloader). Without it you'll reboot to the default OS.
GApps, AKA Google Apps. This will install the Play Store and other Google services. Not required but 95% of people will want this. Select ARM64, 8.1, and then any on the right (Nano is recommended). Hover your mouse over each option for descriptions. If you're not sure just choose Nano.
TegraRcmGUI. This program will push the exploit to your Switch. Grab the latest .msi installer and install it.
balenaEtcher. This program will write the ROM to your SD card.
Hekate. This is the "bootloader" if you will. Once you get to RCM with your jig (or whatever method) this is the payload we'll be sending over. The ROM developer recommends using version 5.0 exactly, and I'll recommend that. Version 5.2+ however does include support for partitioning your SD card so you can use one SD card for Horizon (Switch's default OS) and Android, though I have not been able to figure it out.
I recommend putting the ROM, GApps, shieldifier, Reboot2Payload, and Hekate files all in one folder so your Downloads folder doesn't get cluttered.
Steps:
Insert your SD card into your PC. Backup anything you need to because all data on the card will be wiped.
Open balenaEtcher. Select the "android-XXgb.img.gz" file you downloaded. In the middle make ABSOLUTELY sure the device selected is the SD card you want to use. You don't want to accidentally destroy some other drive you have attached. Click "flash". This can take a while (30mins-hours depending on SD card speed and size!), especially on larger cards. The progress bar will jump around, and get stuck at like 99%. Don't worry, that's fine.
Once it's complete you can close balenaEtcher. You should be able to see two new drives in Windows explorer. One will give an error if clicked (Don't click format when Windows asks!) and another is a 2gb partition Windows can read. If these don't appear then reinsert your SD card into your PC. Mine mounted the unreadable partition as D:\ and the readable one as S:\. EDIT:Redoing this months later it only shows the one drive for me.
Place the GApps .zip (and shieldifier/Reboot2Payload .zip) file(s) in the root of the 2gb partition. Don't unzip them.
Eject the SD Card from your PC and place it in your Switch.
Use your preferred method of booting into RCM. I posted a link with many methods in the "What you need" list up top. You'll know you're in RCM when the Switch screen stays black and doesn't boot as normal when you hold Power+Vol Up.
Launch TegraRcmGUI. Go to the settings tab and select "Install driver". Go back to the payload tab and select the Hekate .bin file as your payload. Connect your Switch. It should say "RCM OK" in TegraRcmGUI. Now select "Inject Payload". Once you see the GUI on your Switch then you can disconnect it.
Tap "More Configs" and then hold down Vol Up and tap "Switchroot Android". Continue holding Vol Up until you get to the TWRP menu.
Tap "Keep Read Only" on the first screen.
Tap "Mount" and check "System" and "Vendor". Then tap the home button at the bottom. (If they don't appear, move your finger up and down in the middle and it should refresh, try that every time it looks like things are missing in TWRP.)
Tap "Install", then "Select Storage", then "Micro SD card" and "OK". Tap the GApps zip, uncheck "Reboot after installation is complete" and slide the slider to the right. Optionally do the same for shieldifier and Reboot2Payload (press back after GAPPS flash to go back). Once finished with all zips wipe the Dalvik cache (it will prompt you). NOTE: If you want GAPPS you MUST install GAPPS before you first boot up Android, so if you accidentally booted into Android, reflash your SD card and restart the guide (you may be able to wipe data and caches through TWRP to fix it, I haven't tested).
Select "Do not install" if it asks to install the TWRP app. Reboot the device (you may have to hold the power button), enter RCM again, and re-inject hekate from your PC. Boot Android again but this time don't hold any buttons. Your screen may be black for a minute, don't panic. First boot takes a while.
Your device should boot into android. Congratulations. Update the NVIDIA Shield app through the Play Store if you installed it. For setting up anything else, or for questions you may have, use the official thread.

Please ask questions, tips, etc, in the official thread! This post is purely to guide users in setting up their PC and such for installing this on their Switch.
You are missing the step where you mount the SD card first before installing GApps. GApps install will fail if you do not mount the SD in TWRP first.

Tap "Install", then "Select Storage" (If the dialog box is blank just slide your finger up and down to scroll and it should refresh), then "Micro SD card".

That works for me AFTER I mount the SD card "System" in TWRP
EDIT: You even said it yourself but missed adding it to your guide. Just trying to help

Ohhhhh you mean mount the /System partition? I think we had a miscommunication. The "sdcard" is automatically mounted, as shown in the YouTube video I hastily made...
I believe the part about mounting the /System partition is only needed sometimes, depending on what you told TWRP to do with the /System partition on first boot. Got ya.

Not much to it. Short pin 9 & 10 and hold down power and vol up. If you can't manage it look into buying a premade jig that does it easily and reliably.
So one side of the paper clip directly on pin 9,10 and the other near a conductive metal? Also there are several options on amazon. (Quickest shopping method) any chance you can point me to the correct one?

Just shorting 9&10 should do it. They're just plastic with a tiny piece of metal inside. Just find one with good reviews.
What's the best way to boot into recovery, this is my first time trying to do anything in relation to modding my switch, any help will be highly appreciated!
everything is working but my joycons wont connect any ideas?
One thing that isn't on here that was required for me was to wipe the dalvic and the cache right after flashing GAPPS. It wouldn't boot aftr that, might be a good addition to your guide. Thanks for the guide though, it was absolutely amazing and got be Android!
Does it cleans the data on switch or just clear the sd card?
Please don't advise people to shove a paperclip into their rails. The pins are susceptible to damage. Advise them to purchase a proper jig, instead.
Does this process make any changes to the Switch? Normally I use SX OS and would rather not mess with it just to try Android.
Will the switch boot android automatically, or do you need to inject hekate from a PC or phone every time you want to boot it?

We asked, he answered. What’s it to you?
Atmosphere and Android
This is awesome news, by chance I had just ordered a hackable Switch today.
Might be a silly question, but I was planning to follow the NH Server instructions to install the Atmosphere CFW
I have ordered a 512GB Micro SD Card for homebrew stuff
The instructions here (Thanks, very clear) suggest that an entirely new / dedicated SD card will be needed for Android.
Anyone planning / see a way to partition and have Atmosphere apps AND Android off of 1 SD card?
Thanks
After injecting payload, screen stays black. Anybody having this issue?
See screenshot showing payload was successfully injected.
