[Q] Nook Tablet BNTV250A boot loop - Barnes & Noble Nook Tablet

So a buddy of mine gave me his nook tablet for free since he practically rage quit it, umm I'm not sure what he did to it but it's stuck in a boot loop, any simple solutions, I'm good with adb but am clueless when it comes to fastboot, I have a factory/fastboot cable which I use for my Kindle Fire HD, which I heard also works on Motorola devices, any chance the factory cable would work with this tablet anyone ever try it? I'm honestly just hoping there is like a one click or so tool to help me fix it, maybe a firmware flasher? I mean if it comes down to it I'll do it all manually but if you guys have any tutorials, tools, guides, etc to help me fix this boatload I'd greatly appreciate it

You did not elaborate what the device boots to: e.g., cyanoboot? recovery? stock boot?
I'd suggest that you burn one of Succulent's pre-made SDcard CM images from his repo http://goo.im/devs/succulent/acclaim/cyanogenmod/image (just download, extract .img file and burn it to SD using win32diskimager or DiskImage_1_6_WinAll) and see if the NT would successfully boot and run the CM image off SDcard.
If it does then you can proceed to restore custom or stock ROM on the internal emmc (e.g., see Info/Tools for Restoring to Stock at http://forum.xda-developers.com/showthread.php?p=48612997#post48612997).

[Q] nook tablet cyanoboot-loop

Since it would of been alot to type out I made a video and to show the problems.
---> Video
I also tried running CM7 off a SD and it was a no go as well. The only thing that will boot off a SD is CWM.
Thank you for your help.

use this link and carefully follow directions-it will fix your problem if you can boot sdcard with these instructions
you will return to stock 1.4.0 factory - better than unusable

The easiest way is to install cm9 alpha 0 (although it is an alpha, so be prepared for issues with the OS itself, plus remember that as an anti-profiteering measure it expires. read the full thread for more info....). When you use cyanoboot on emmc, you need to move the contents of boot.img and recovery.img so that they start at block 512. You can use dd or fastboot to put them on emmc...
See the original CyanoBoot thread as it talks about the above in a lot of detail, tho probably more than you need.
I read your post like five times I've flashed many Roms and did many things with phones and tablets. But I don't know what you mean by putting it at 512 or something I'm still a noob know how to flash move some things but when it comes to this I'm kind of lost

+1 to this, i'm trying to figuring out how to install it on emmc, in the post you get the idea of what you need to do but not how to do it, i mean what commands run,etc to install it. Say i want to test CM9 and want cyanoboot installed internally.
Could someone that has succesfully installed it internally (emmc) post proper instructions for this. TIA.

This may not be the exact answer you're looking for, but if you want to try it, just flash the newest CM9 (alpha 0.03) as it will install Cyanoboot to eMMC as well. I believe it's all contained in the CM9 boot.img.
There is no padding if you use flashing_boot.img on sdcard.
For emmc/internal, you need to pad flashing_boot_emmc.img to 512KB.
You have to pad flashing_boot_emmc.img correctly or else it can't find boot.img/recovery.img so you end in a bootloop.
dd if=/dev/zero of=flashing_boot_emmc.img bs=1 seek=524287 count=1
flashing_boot_emmc.img is then filled with zeros so the file size is 512KB. You then need to append boot.img or recovery.img to it.
cat flashing_boot_emmc.img boot.img > new_boot.img
Your new_boot.img can now be flash.
I haven't use cyanoboot, but bauwks 2ndboot method is the same except you need to pad it to 256KB.
You can gain cyanoboot by flashing my mmcblk0p2 i uploaded here, if you like

I think the reason your post has not been answered is because we don't know exactly what you're asking. Also most answers are already posted. You just have to search and read them.
I'm not sure what you're doing myself, but I think you need to use Odin to flash CWM recovery and then use that recovery to flash ROMs, kernels, etc...
Since I really don't know what you're trying to do, you need to make sure what I said is REALLY what you need to do. By searching and reading you will find your answer.

tq very much.. right now, i'm trying to do just like u say, if it works, i'm in your debt..
what i meant was, that my android recovery system cannot detect the path to SD card, since the gt-p7500 did not have any SD Card slots, so i can't flash any .zip files from my tab.. Thanks so much..

One of the partitions on your tablet is mounted as /mnt/sdcard (or /sdcard). You normally push files there using USB from your computer, either using "adb push" or mounting the sdcard as a media device on the computer.
Stock recovery does not let you choose a file from the /sdcard directory. I think the errors you're seeing is that the stock recovery isn't finding the files it's looking for.
You'll need to install Clockwork Mod recovery if you want to flash custom ROMs.
Galaxy Tab doesn't have an SD Card slot, so anything with external storage/mounting USB/ etc won't work in recovery. Flashing a ROM is possible because the data partition is read and treated as SD Card. If you need to add something to your tab via USB while it's in recovery, you'll need to use the Android Debug Bridge and type adb push, then the file, then the destination.
Example:
Code:
adb push rom.zip /sdcard/

[Q] not sure where to go.

I got a nook tablet recently, i registerested it already which i understand you have to do... now i want to backup everything and run regular android as in not B&N version. Im not sure which way to go from here, i see there is an sd option and a regular option?
i was reading this
http://forum.xda-developers.com/showthread.php?t=1439630
as i was getting ready to do it, i started to double think if it was what i wanted.
i want to be able to run the latest android rom possible.
appreciate any help, thanks.
The process you are linking to is very simple and "safe". With the card you create you can startup CWM (ClockWorkMod - utility for flashing and backup and more) and not only root your device, but also make a backup, should you want to go back to where you were prior to flashing whwaever you decide to flash.
The rooting alone lets you install apps from other sources than BN. I think rooted stock tweaked a bit isn't too bad to run actually!
To try out other options completely risk free you can run CM10 (ICS) from an sd card. I do that while I wait for CM10 to be more stable/bug free. It runs incredibly well from sd, and I doubt performance will be greatly enhanced onec I install it internally (as I probably will do at som point.
To run from sd card you don't have to root the device unless you want to.
Great guides for making a sd-card are here and there. For example http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/
The first thing I would suggest is to make a bootable recovery SD card using the process and files from here (use the MLO_u-boot_flashing-boot.rar and one of the packages with sdcard.zip suffix), and backup your current stock config and safely save/archive the backup folder -- you'll be glad you have it around one of these days. Make sure that you also keep a copy of whichever recovery program version you choose to use together with the backup folder, since different recovery programs and versions use different backup file archive formats.
If you want to root the NT I would recommend using the update.zip referenced in this post (by liquidzoo) which is more up-to-date than the rooting package you saw (I had used the latter version and had problem updating its Google Store app). Just put this zip package on the same recovery SD card and use the recovery program to install it.
Having tried out the rooted form of the NT for about a week I think it's just marginally better than a stock NT -- there are just so many common apps that are no longer available for the NT's Android version. You would be much better of investing time in going full-fledge CM10, either running off an SD or natively. If you choose to go native CM10 you can revert back to stock using the backup discussed above.
Can you please verify if I am doing the correct thing
@digimax,
I just got my Nook Tablet today, so just wanted to be very clear to make the backup of the current stock config. Here's what I propose to do. Please correct me if I am doing anything wrong.
1) As per you post, I downloaded 3 files
a) MLO_u-boot_flashing-boot.rar,
b) CM9-10_CWM_V6.0.1.2_8-16gb_tools_sdcard.zip,
c) CM9-10_TWRP_v2.2.2.0_8-16gb_tools_sdcard.zip
2) Unzip all the above 3 files
3) Rename the CWM file to recovery.img
4) Rename the TWRP file to altboot.img
5) Copy recovery.img and altboot.img and MLO, flashing_boot.img and u-boot.bin to the root of the SDCard.
6) Insert the SDCard into the Nook Tablet and boot the Nook into one of the recovery and make a backup.
Please let me know if this is the correct procedure.
Thanks!
It looks right, make sure that your boot partition is Primary FAT32 (type 0x0C) with LBA and Active flags set (you can check and set all this using a partition management tool such as MiniToolPartition).
Also, to boot into SD: just turn off the NT and insert a powered-USB cable, and the NT will boot up after a few seconds (assuming that the SD is bootable).
Once CyanoBoot comes up, hold the "N" button to get the boot menu from which you can select one of the two recovery programs.
a lot of this is going way over my head, i need to make sure i go slow and read carefully.
thanks for all the info.

Remember that you can make CM10 run totally risk free from am SD-card. That way you can have a smooth running device to explore while you keep reading up on diffrent options. That's what I do! The Tablet doesn't even have to be rooted to do this (mine is though).

Look through the comment sections for further clarity on the process.
If that is beyond you, then I suggest getting a pre-made image for the size of SDCard you have and burning your own image. Google AndroidforNook or N2A for the website links.

What do you mean? You have to manually download the recovery program. Rename it to recovery.img and place it in your BOOT partition in replacement of your current recovery.
I mean within GooManager, select install open recovery script installs 2.14,
Could you please elaborate on how to copy it to the boot partition? Can that be done from within the device, or do you need to be connected through USB/adb?

I went ahead and used fastboot to update my recovery, and I understand that using the flash_image binary is a second option, but this instruction has me curious if there's a third way to do it. Any further details would be appreciated.
In case it helps anyone else, I thought I'd document a couple of the "gotchas" that I ran in to. Some of the guides I'd read didn't seem to cover a key point here or there.
Obvious to the experienced dev, I didn't realize that for fastboot to work I actually had to boot to the cyanoboot screen and 'start fastboot', then run the fastboot command on my pc. /facepalm
Windows (I'm on Win7) detected the NT with a different PID (physical ID?) in Device Manager depending on whether I was booted into cyanoboot, recovery, or fully into android, so I ended up modifying android_winusb.inf three times and installing the drivers three times, once for each state.
I too wonder why Goo Manager doesn't install a newer version. But... I'm glad for the experience of installing the ADB SDK and using fastboot.
Cheers!

Connect your USB cable to the computer and find your device's BOOT partition. Should be a FAT32 partition so Windows can read it. Replace "recovery.img" with whatever newer recovery you want. That's how I replace the recovery. I'm using a SDC version so I can also change it on my tablet. I go to /storage.sdcard1 and replace recovery.img from there.
That sounds easy. Surely there's a catch!?:thumbup:

Recovery is located in /boot only in SD-based ROM image. When running ROM internally on emmc, Recovery is located in /recovery partition. Also emmc and sd recovery use different versions of recovery.img.

[Q] root question??

I have an 8gb nook tablet that I rooted probably 2 and a half years ago and haven't changed anything on it since. I am wanting to undo and update to current root and flash a 4.4 rom like on my phone. What is the best way to go about this? I know how to unroot, I just need to know the best way to root currently. Thanks.
Custom ROMs like CM comes with built-in root capability, and moreover once installed replaces completely the existing ROM currently in place (be it stock ROM, rooted stock ROM, or another custom ROM). As such, there is no need to root (or re-root) prior to flashing a custom ROM. See http://forum.xda-developers.com/showthread.php?t=2575489 for more background info and pointers.
Cool, thanks for the reply and links. I have some reading to do.

It should work (with the usual caveat YMMV). Flashing CM11 requires CWM version 6.0.4.5 or later, or TWRP version 2.6.3.0 or later (in step 2(b) of http://forum.xda-developers.com/showpost.php?p=43326042&postcount=123); you can find the SD version of TWRP 2.6.3.x at http://techerrata.com/browse/twrp2/acclaim. You also need a recent Gapps version corresponding to the CM11.
Alternatively, if your NT is already on CM10.x (as my NT was), you can:
download CM11 ROM and the corresponding Gapps zip files onto your NT (user content media partition).
use SD based recovery to flash a flashable emmc CWM zip (http://forum.xda-developers.com/showpost.php?p=48855275&postcount=2) or flashable emmc TWRP zip (http://forum.xda-developers.com/showpost.php?p=49111924&postcount=8) into emmc.
remove SD then boot onto emmc recovery (which is installed in step 2) and use it to install the ROM and Gapps zip files downloaded in step 1.
Remember to use SD based recovery to backup your current ROM before flashing CM.
I need help once again. In step 2a. of Installing CM10.1 Internally on Nook Tablet, I do not see the boot.zip with the 3 files needed and I am not sure how to extract them from the .img file from the pre-made SDcard images. I've only used linux like once and that was to root my Droid DNA. Thank you for your patience with me.
Nevermind...I found a Linux Reader program that let me extract them.

For future reference, you can use 7-zip (which is available for windows) to open .img files and extract its content.
