Hey guys....really getting a lot of info from these threads, especially this one...Thanks Jichuan for starting it.

Maybe you guys can help me: I've been trying all weekend to make this decision: Just got the NC but I may return it for the 8GB NT. For $30 more, is it really worth it to get the 8GB NT? Do the benefits of the 8GB NT have a big impact that "the average user" would notice and might therefore have remorse about not splurging the extra $30? Seems like (so far) the 8GB NT is one big headache to mod it and I'm really not into tinkering around with it once I can access CM7....call me lazy but I'd be happy just using an SD card to be able to dual boot and run CM7 or the original Nook OS if I choose. I don't want to have to keep searching the threads and doing mods each time B&N sends out an OTA update which it sounds like tend to "break" the mods you folks have worked so hard to create (unless you can disable the OTA - which sounds like it works sometimes and sometimes not).

Can you please advise or help me decide?
[Barnes & Noble Nook Tablet] jichuan89:
Hmm...you seem to have done everything right. The only possibility I can imagine is that maybe your SD card was still mounted when you burned the image (as seen from your included snippet), and other processes could have corrupted the newly created file system on the USB stick. The command to unmount a drive in Linux is unfortunately spelt 'umount', not 'unmount'. Can you try going through the same steps, but this time correctly unmounting the drive?
[Barnes & Noble Nook Tablet] Farleytron:
IT WORKS!

Thanks Jichuan!

I am SO relieved!! I repartitioned the sd card and dropped your files onto the card.

It booted properly, and rooted the Nook!

YOU ROCK! I was going insane trying to root the damn thing for the last four days.

:D:DJICHUAN RULES!:D:D
[Barnes & Noble Nook Tablet] lictenau:
new launcher gone again after I hit the "n" button. any way to relink the button?:mad:
[Barnes & Noble Nook Tablet] jichuan89:
To get back to your custom launcher, you'd have to use the good-ol' search ("n" button -> Search). To permanently switch to your custom launcher as the default launcher, you can install the HomeCatcher app (http://xdaforums.com/showthread.php?t=1357175). Before you do that though you'd have to enable the installation of APK files (or installation from "unknown sources" - I recommend using the "NT Hidden Settings" app which is available on the Android Market).
[Barnes & Noble Nook Tablet] Farleytron:
Donated

I donated $5 for your awesome work.

Thanks again!

Thanks!! Glad to be of help :)

Can you help me modify it so it flashes/copies the whole system over? My NT is brick and I need to copy everything over (especially /boot).
[Barnes & Noble Nook Tablet] jichuan89:
Have you tried http://xdaforums.com/showthread.php?t=1420408 ? I bricked mine a couple of days ago when I flashed a bad boot.img via fastboot, but was able to use the above method to restore all internal partitions to stock.
[Barnes & Noble Nook Tablet] teddykgb715:
I'm grasping at straws here, but does anyone know if I should unmount or "eject" the sd card in Windows before flashing the image to it? Just trying to think what I could do differently to maybe get the damn thing to work! :)
[Barnes & Noble Nook Tablet] kr00lplatinum:
kr00lplatinum

In Linux Mint 12 KDE I followed the directions exactly and made sure to umount /dev/sdd.

I then copied all the files over to the micro sd. I put it in the NT and got the same results as before. My NT has firmware version 1.4.2 . Using the Win 7 method gives me the same results.

What firmware version do you guys have on your NT8gb?
[Barnes & Noble Nook Tablet] jichuan89:
Hang on - you should not touch your SD card in any way after running dd. Basically, when you're in Linux,

1. Unmount card.

2. Run dd the way you're already doing it.

3. Take out the SD card physically. Do not eject drive on your computer or view / modify it in any way.

4. Insert SD card into NT.
[Barnes & Noble Nook Tablet] kr00lplatinum:
Yeah, that's what I meant. I did exactly as you described above and still have no success. I meant that dd places all the files on the micro sd.

Sorry, for the confusion.
[Barnes & Noble Nook Tablet] jichuan89:
Huh. Stumped :(
[Barnes & Noble Nook Tablet] jichuan89:
Btw, can you run 'md5sum jichuan89_nook_root_sd.img' in Linux and see if you get this:

[Barnes & Noble Nook Tablet] ajprog:
It doesn't work I need do restore from a sd card, that is why I asked the question how do I modify your copy script?

Can I get copies of the source for those img files?
[Barnes & Noble Nook Tablet] bignish:
still not working

I have unsuccessfully attempted this process quite a few times. I am using method 1 and I believe it imaged correctly but when I attempt to load it boots right past the card. However if oi select the card icon at the bottom left corner of my screen and browse the content on it I can see the files are there.

What can I be doing wrong? Is my problem with burning the image? Do need to safely remove my card after writing or just eject it when I'm done? I am using Windows.
[Barnes & Noble Nook Tablet] jichuan89:
OK I'm out of ideas :(
[Barnes & Noble Nook Tablet] kr00lplatinum:
I'm having the same problem... He doesn't know how to fix it yet.
[Barnes & Noble Nook Tablet] jichuan89:
You should take out the SD card directly after burning the image, without "safely removeing" it. Since I don't have access to a Windows machine at the moment I can't really debug Windows-related problems for a while, but an earlier post said it's possible :/
[Barnes & Noble Nook Tablet] jichuan89:
To get the sources and rebuild the images, you will need a tool called abootimg. Grab the zip file linked in option 2 in the first post and extract that. Then run 'abootimg -x boot.img' in that folder, followed by 'abootimg-unpack-initrd'. You should now have the sources for the ramdisk in the ramdisk/ folder. Modify files under ramdisk/ as you wish. Then when you're done go back up to where you extracted the files and run 'abootimg-pack-initrd'. You now have an updated boot.img that contains whatever you've put under ramdisk/ that you can copy to an SD card.
[Barnes & Noble Nook Tablet] teddykgb715:
Since I'm having similar issues, I'll try this tonight.
[Barnes & Noble Nook Tablet] teddykgb715:
Nope, no difference. Bummer.
[Barnes & Noble Nook Tablet] bignish:
Me neither.
[Barnes & Noble Nook Tablet] jichuan89:
For people whose tablet doesn't boot from the SD card (no box with SD card inserted): the 16GB NT won't boot from SD card unless "tethered", i.e., connected to a computer. Can someone try the following:

1. Power off the tablet;

2. Insert microSD card;

3. Connect tablet to USB slot on computer.

The tablet should boot on its own without pressing the power button; if not go ahead and press the power button. Does that change anything?

----------------- EDIT --------------------

User MrChefBoiRD on YouTube says that his 8GB tablet does not boot from the SD card normally, but does boot when plugged into a computer. Can anyone confirm this?
[Barnes & Noble Nook Tablet] teddykgb715:
BINGO! Got the box. Waiting....and....we're rooted! Nice. Thank you!
[Barnes & Noble Nook Tablet] jichuan89:
NICE :cool: Looks like the tablets aren't born equal - some of them would boot from a microSD card only if plugged into a computer, while others (like mine) boot fine on their own. Hmmm.
[Barnes & Noble Nook Tablet] bignish:
This is definitely true, because mine still won't do either :confused:
[Barnes & Noble Nook Tablet] teddykgb715:
So are we able to install roms yet? I cannot get sideloading to work and I need to get rid of the stock homescreen!
[Barnes & Noble Nook Tablet] jichuan89:
1. Sideloading: install "NT Hidden Settings" from Android Market, run it and hit "Unknown Sources Hack".

2. Home screen: install a custom launcher, then install HomeCatcher app (Google for it; you will need to do step 1 because it's an APK file you need to download & install). Then when you press "n" and select "Home" you will be prompted to set your preferred launcher.
[Barnes & Noble Nook Tablet] Farleytron:
Everyone should be donating to Jichuan.

He is the first and only person to create a working root for the 8GB NT.

Please send him something to show your appreciation!

And for those people having a problem, it might be your SD card.

The Nook is really sensitive about card quality.

It also needs a fresh bootable partition to work.

Here's my advice:

Use an SD card reader, cell phone, camera, or something. Do not use the Nook. I used an old cell phone.

Using Windows (I used 32 bit Win7), download and install EASUS Partition Mgr (freeware)

Partition your card in EASUS Partition Mgr with a single 50MB FAT32 partition, name it BOOT, and set it to "active"

When the 50MB partition appears in Windows explorer, drop the files from Jichuan's pack into the directory.

Use the "safely disconnect" icon in the system tray to eject the card. Some say it will keep the card from getting corrupted.

With the Nook powered off, put in the sd card, connect the USB cable to your PC, then hold the N key and the power button til the Nook boots. If you see the Bauwks cardboard box, LET GO of the buttons. If you only see the Nook logo, keep holding it until the Nook shuts off. Then wait about 10 seconds and hold the power button and the N button again.

If you STILL don't see the Bauwks box, you might need to try a different card.

Worked Great

Registered just to add to the count of confirmed working cases. Bought my 8 gig NT tonight. Used method 1 , tethered , win 7 64. Worked without any issue.
[Barnes & Noble Nook Tablet] teddykgb715:
I swear I did this, but after trying again this morning it works great. Double press on the N takes me to go launcher now! Nice.
[Barnes & Noble Nook Tablet] teddykgb715:
So I'm obviously not clear on how all of this works, but can we install CM7 on the 8gb? Can we install CWR?
[Barnes & Noble Nook Tablet] bignish:
Okay, so I've tried this and everything else and still no box. With this my screen just powers on and off and if I let go of the Power and n buttons I get the question of do I want to power off or do a factory reset.

I am using a brand new 16 Gb class 4 Sandisk. What other card do you suggest? Or what else could possibly be the issue?
[Barnes & Noble Nook Tablet] teddykgb715:
I did not do power and n buttons, just turned it on. His post was the first time I saw that. If you haven't tried just turning it on with everything else the same do that.

EDIT: I also ended up not doing "safely disconnect" FWIW. I just pulled it.
[Barnes & Noble Nook Tablet] bignish:
Nope, tried that too. I have basically tried everything on here and still nothing. I am the only one with no results so I'm just about ready to give up. Thanks though.
[Barnes & Noble Nook Tablet] cheddleson:
Don't give up yet, no results here, either. Just seems to boot right past the sd card. Doesn't seem to matter whether I try to boot while tethered or not...
[Barnes & Noble Nook Tablet] jichuan89:
Farleytron is right about cards and card readers. People who still can't get your tablet to boot - perhaps you could try a different card and/or a different card reader? I for one am the owner of a card reader that won't write this image properly.

And @Farleytron - thanks a lot for the warm comments! :)
[Barnes & Noble Nook Tablet] jichuan89:
Depends on the meaning of "can".

It is certainly possible; theoretically, to boot a ROM for the 16GB NT on the 8GB you should only need to modify the kernel command line in the boot.img of that ROM to accommodate for the difference in memory. However, some mods for the 16GB NT might be using bootloading code from earlier versions of the B&N firmware (1.4.0, 1.4.1 etc) and will therefore need to incorporate the changes from the 1.4.2 firmware to be able to boot on the 8GB. But once booting the kernel is solved, everything else should work without modification.

If you mean whether we can we install CM7/CWM right now, then AFAIK no one's made these modifications for the 8GB NT yet, so no. My personal impression (which is quite possibly wrong) is that all this stuff (CM7, CWM etc) is still experimental (read unstable) even on the 16GB model, and the devs are too busy solving the existing issues on the 16GB versions to start porting it to the 8GB.
[Barnes & Noble Nook Tablet] pfunk123:
My nook has been "bricked" for the past week and after trying everything and every other method, this one finally powered mine back on. Well thats about all I got it to do but hey its a start. Ive followed the instructions for windows method and get the box and read forever logo, leave it alone for a couple mins but when I power off and try to reboot I get nothing. Tried plugged in plugged out, card in card out and still no go. Much props for the Good Work nonetheless!!!
[Barnes & Noble Nook Tablet] cheddleson:
I posted earlier about not being able to book from SD, but have just tried the SD version of CM7 with no problems. Does anyone with more knowledge than me have any idea why I can boot an entire operating system from sd, but can't get my Nook to boot these rooting files from SD? Oh yes, I had to be tethered in order to boot CM7...hope I'm not doing anything wrong... and thanks for all your work making the NT a lot better than stock!
[Barnes & Noble Nook Tablet] yang.joonyong:
cant download anything from market?

Hi,

I have successfully rooted my nook tab (8gb) but I cant seem to download any applications from the market.

Everytime I try to download for example launcher, NT hidden settings, it just says the app can not be downloaded due to an error.

anyone experienced and solved a problem like this?

Thank you!

---------- Post added at 08:10 AM ---------- Previous post was at 07:52 AM ----------

well it eventually just worked itself out but can anyone tell me how to install apk files in nook tab? sorryy
[Barnes & Noble Nook Tablet] jichuan89:
Glad you got it working in the end.

See post #58 in this thread.
[Barnes & Noble Nook Tablet] yang.joonyong:
hmm yea I downloaded NT Hidden Setting and clicked the unknown source and I placed the apk file into my sd card and tried using root explorer to install the app but I am getting errors =(

and another thing is, is there anyway to get to android menu so I can activate other keyboards that I download?

Thank you
[Barnes & Noble Nook Tablet] Farleytron:
Use adb to sideload.

"adb install <path to apk on your windows machine>' with USB debugging on from NT Hidden Settings
[Barnes & Noble Nook Tablet] jokersone78:
Im in the same boat my friend but im confident that eventually someone will figure it out.;)
[Barnes & Noble Nook Tablet] jichuan89:
So there can be multiple ways your tablet is "bricked". If you flashed a bad boot partition, your tablet should not boot past the "READ FOREVER" screen (so you won't see the "by Barnes & Noble" animation); in the worst case it will power off right after the initial dark "n" screen. If this is the case, I've made an image that will restore your boot partition.

On the other hand, if you destroyed your /system partition (by itself or the boot partition as well), this won't help you. If this is the case for you, post in this thread and I can make an image that flashes the /system partition as well.

1. Download one of the following depending on your hadware / OS version:

8GB NT/1.4.2: http://www.mediafire.com/?a803src02leyfq7 MD5: 79265f4730a1b0a0131cfb7e64f0d2bb​

16GB NT/1.4.2: http://www.mediafire.com/?pjbmcp7zpw9ciua MD5: 28a44b20ce497bb7a3d43219d344408d​

2. Make a bootable SD card following the instructions in post #1; either option will be fine.

3. Replace boot.img on the SD card with the file you downloaded in step 1; i.e., rename the file from step 1 to boot.img and overwrite boot.img on the SD card from step 2.

4. Power off tablet.

5. Insert SD card into tablet.

6. Connect tablet to computer via USB cable. If tablet does not start automatically press the power button.

In the best case, if you have not destroyed your /system, you should be able to boot back to stock, although it should take a while to boot. Otherwise, reply with your tablet model (16GB/8GB), what you did to brick your tablet and what you see when using this method.

I really do need feedback on this so please post back regardless of whether it worked.
[Barnes & Noble Nook Tablet] pfunk123:
Ok Ive searched and tried about everything I could of to get my 8gb NT to boot and turn back on. Your method from post 1 by far has gotten me the closest. A day old and I jumped the gun and downloaded "acclaim_update.zip" without even carefully reading. By the time I found out it was not meant for the 8gb, ive already made a card and popped it in the tablet, that was the last time I seen the screen on. Now after trying your root method I can get it powered back on, the cardboard box, and the read forever screen but no further than that.
[Barnes & Noble Nook Tablet] jichuan89:
Can you try out the method in my previous post (#76)? Can you get into the factory restore interface after 8 failed reboots?
[Barnes & Noble Nook Tablet] pfunk123:
Ok please correct me if Im wrong, download the file that you attached in your recent post for the 8gb version, the downloaded file "jichuan89_nook_restore_boot-8gb" then needs to be renamed to "boot.img", open win32diskimager and locate "boot.img" and write it to my empty fat32 formatted card?
[Barnes & Noble Nook Tablet] jichuan89:
NO. Write out the image in post #1, for instance using Win32DiskImager. Eject your SD card, and plug it back in to the computer. Now open up the SD card on your computer and you should see a "boot.img". Replace that file with the file jichuan89_nook_restore_boot-8gb.img. Then eject the card again and put it into your tablet.
[Barnes & Noble Nook Tablet] pfunk123:
Ok did just that. Loaded card with the updated boot image, plugged in usb cable, it powered on itself, now have the box screen and as we speak it will be goin into the 5th minute of being on this screen. Is this making progress, whats next from here?
[Barnes & Noble Nook Tablet] jichuan89:
Yes, as I said in post #76 this new image should quite a while to boot. This is because it's extracting the stock boot partition image I pulled from my own 8GB tablet and flashing it to yours. Do not turn off your tablet yet; let me know when you get past the box screen.
[Barnes & Noble Nook Tablet] pfunk123:
Well since my last post which was about 4 hours ago its still on the box screen. Should it have moved on by now or is this usual?
[Barnes & Noble Nook Tablet] jichuan89:
No, that is not usual. The box screen is shown when the 2nduboot bootloader loads my boot.img (kernel + ramdisk) into memory; it should take at most a couple of minutes as it does on my tablet. Looks like yours is simply refusing to boot my boot.img, so you should be able to safely power it off. Since I can't replicate this behavior on my tablet where it boots fine I can't really help at this point...
[Barnes & Noble Nook Tablet] pfunk123:
:D Your the BEST!!!!! I figured I start from the beginning again but this time with a fresh new card. Did exactly what you said in post 76 and soon as I popped in the card and plugged up the cable, 2 mins later I saw the life of my tablet come back alive. AWESOME!!!

So if I wanna go ahead and do the root I would just swap back the boot images?
[Barnes & Noble Nook Tablet] cheddleson:
Anyone having trouble getting this to work, try to download the files over. I was having problems even though md5's matched. Deleted all the files, downloaded again, and am now rooted. Thanks for the work put in getting this done!
[Barnes & Noble Nook Tablet] jokersone78:
it worked but now i cant use the n button also i cant use the system restore in the settings menu.
[Barnes & Noble Nook Tablet] JonNotJohnny:
Is it me?

So I got a Nook tonight because I was told it was the easier of the low cost tablets to root. In other words I got it at exactly the wrong time.

After some searching and several Youtube videos, I found this thread and I think all of my problems will soon be solved. Let me get straight to the point.

Step 1 Done.

Step 2 Done. Downloaded it twice now.

Step 3 Everything falls apart. According to the instructions on the Nookie FroYo page, I should be able to extract the files with 7-zip. Can't do it. I keep getting told there's an error with the image and it stops. A fresh download yields the same results.

I'm running Windows 7 if that helps. Is there another place I can try to get the image or should I try using a different extractor? I don't want to brick my new device but my confidence is slowing since I can't seem to get the one file I need to download completely.

Any help would be greatly appreciated.

Thanks!
[Barnes & Noble Nook Tablet] jichuan89:
That's unrelated to my restore image. Can't help you there I'm afraid.
[Barnes & Noble Nook Tablet] jichuan89:
Why aren't you using option 1, which is the easier of the two? You don't need to extract anything there.
[Barnes & Noble Nook Tablet] JonNotJohnny:
Oh, believe me I am. 10 seconds on the video for option 2 made me want to curl up in the corner and sob.

The reason I'm extracting is that's what the instructions for the Nookie FroYo say to do. Am I overthinking this?
[Barnes & Noble Nook Tablet] jichuan89:
Yes. Like I just said, you don't need to extract anything if you're using option 1. Skip to step 3 on the Nookie Froyo page.
[Barnes & Noble Nook Tablet] esthernrob:
after root, will i still be able to access my B&N books that i've purchased? looks as tho all original data on the tablet is lost? also, is there a way to un-root if the need be? TIA
[Barnes & Noble Nook Tablet] jichuan89:
Yes.

No. You will not lose any data.

Yes. All rooting does is install a bunch of files to /system; to unroot you just need to delete those files. AFAIK there isn't a reason to unroot the NT, but if one day there is I could make a bootable SD card for that.
[Barnes & Noble Nook Tablet] esthernrob:
thanks for the quick reply... gonna give it a go right now...
[Barnes & Noble Nook Tablet] jokersone78:
also i cant boot without the sd card installed is that normal?
[Barnes & Noble Nook Tablet] jichuan89:
Depends on what you mean by "can't boot". You'd have to describe exactly what your tablet does when you power it on without the SD card. Which screens are you seeing and what happens in the end etc.
[Barnes & Noble Nook Tablet] jokersone78:
i see nothing without the sd card in and the usb cable conected but once it gets to the home screen i can unmount the sd card and reemove the usb cable.

small SDcard boot issue

Hi

I tried the boot method 1 in your instructions w. a 512M and 256M SDcard I had lying around. Neither one gets to the initial cardboard box boot screen. I just see the n symbol and it boots in as normal. Tried putting the image on Windows and mac with same result. Is it possible that the SDcard density needs to be some specific range for this to work?

Thanks
[Barnes & Noble Nook Tablet] songjacked:
I had the same issue rerooting my 8GB earlier today. Perhaps there's something wrong with the .img or the WinImage version?

I eventually got it to work properly using the tools and image provided in http://xdaforums.com/showthread.php?t=1439630. Wrote that image to the SD, then just replaced the files with those provided in the OP's .zip. HomeCatcher didn't seem to be installed, but that was easy enough to sideload with ADB. Root and Market worked fine, though.
