Hi,
Issue: After rooting my Nook Tablet I inadvertantly rebooted into factory reset. I cancelled the reset but after this point whenever I boot the device the following occurs:
The nook copyright screen appearsThe reading forever screen flashes for a fraction of a secondThe download/restore indicator with the green arrow appears for a fraction of a secondThe nook tablet logo appears with an exclamation mark with the instruction to "Please restart your device and try again. If you encounter the same issue please contact customer service ..."
Attempted Fixes: Naturually I have tried rebooting resulting in the same process being repeated. I have also tried the acclaim_update.zip sd fix but have had no luck running it from the sd. I have also tried the 8 x reboot method to no avail. Any attempts to use adb have thus far failed (the device is not even detected properly).
I understand that everyone is busy but if anyone has any suggestions I would be much obliged. I do not live in the US so returning the device is extremely difficult. I run Linux and have an XP virtual machine available.
Thanks for your time
Have you tried booting cwm from an sd card and then reinstalling a stock rooted rom like this http://forum.xda-developers.com/showthread.php?t=1488035
Unfortunately no luck booting cwm from sd - I have not managed to get anything to boot from sd. Thanks for the suggestion though.

Did you try to boot from sdcard while connected to your PC with the USB cable?

Update: Issue resolved - I ended up using AdamOutler's Ubuntu Wipe, which did hang indefinitely on the 'Overwriting sys with zeros' stage but did actually result in a factory reset.
Thanks to lavero.burgos and nba1341 for their assistance. I did successfully manage to boot CWM off an sd (my mistake was not formatting it as a boot partition), however I was unable to successfully flash any roms. Anyway I'm back to normal and ready to try again. Thanks all!

Hi Guys,
I really hope someone can help me out with this issue. I searched the forum and the internet but did not find any solutions.
My friend successfully rooted the Nook Tablet yesterday using a method that did not require an SD card. Today I was trying to install CM9 with ICS so I downloaded Nook Recovery Flasher.apk and flashed cwm. When I restarted my device got stuck into autorestarting loop. It shows the gray "n", which quickly followed by the clockwork recovery loading splash screen (the picture of the cardboard box). The device then shuts down and starts the cycle over.
I've tried holding the power and n button method but that doesn't work. I've also tried creating a bootable sd card but the device won't pick that up either.
I would appreciate any suggestions!
I've ended up bricking my 8GB NT a similar way. Ended up writing over my mmcblk partition with something I wasn't supposed to. Now stuck in a reboot loop, can't do adb, my phone isn't playing nice enough to where I can make a recovery SD.
BTW OP, from what I've read CM9 is only for 16GBs and will brick 8GBs.
Same thing happened to me a while back. I was able to create a bootable CWM sd card. From there you should be able to restore. If not, use the Ubuntu recovery.
Short answer: You're going to have to create a bootable SD card.
Hi all,
please need your help with my nook tablet, got bricked after trying to intall CWM, after that tried the ubuntu fix, I guess it didn't work until the end, so now got the "n" logo at the boot, and the message of battery low appears everytime, but it stayed in the plug whole day. don't know what happned, can't boot from SD.

It should be able to boot from the SD card because the nook automatically boots from there first. Try installing the latest version of of CWM onto the SD card and do a factory reset from there.
Here's the link for CWM Recovery. h ttp://goo.im/devs/succulent/acclaim/recovery/CWM_6.0.2.7_Nook_Tablet.7z
The story began when I decided to install CM10 on my nook tablet using old recovery that goes for CM7 and eventually broke my partition table and lost my ID(./adb devices shows 0000000000000000). Since my nook refused to boot futher than CWM loading screen (box) i decided to recreate my partitions through ADB using this method and then reflash nook with AdamOutler's Ubuntu recovery (he provided his own mmcblk0p5).
So, I succesfully recreate partition table (everything was in order, I checked a few times) and reflash it with Ubuntu recovery. Interesting part starts here. Now i get "bla-bla-bla please restart your device" and picture with exclamation mark. A couple of reboots gave nothing and brought me to the same screen. Reflash with BN factory recovery as well as factory reset did not work. At that point I decided to inspect partitions again. Everything was ok, formating, size, etc. But my ID still was 0000000000000000. This brought me to the conclusion that something is wrong with mmcblk0p5 and i need to flash partitions with dd again using this files (method). So, all went well without errors, at the end i killed adb server, dismount SD and pressed "reboot device" in CWM menu. And... From that time my nook is completely dead.
It didn't respond to any key. I charge it all night. I tried to hold home+power simultaneously. No response. Connecting to a computer or power outlet is also nothing.
Be kind, I'd like to hear your advice. Sorry for my runglish.

I'm having the same problem. I downgraded from 1.4.3 to 1.4.0. I was able to boot it once and then shut it back down so I could root it. Now it won't start up at all and I have tried everything that I can find to boot it to no avail.
The NT can sometimes get stuck in limbo while booting up, especially with SD-based boot. To get out of it, hold down the power button for 20-30 sec to turn it off then power it on again. Also remove any "bootable" SD card from the card slot; if it boots then the card was not bootable and its non-bootability was the problem.
It's also possible that the NT battery is completely drained (battery readings on some CM builds can be quite off, sometimes as much as 20 points) in which case you'd need to use the BN wall-charger and charge it for 8-12 hours.
I attempted to root a denver tac-70061 tablet in order to be able to switch the mounting of the internal and the external sdcards. I have only rooted once before; a denver tac-70031 tablet which was extremely easy to root by simply installing and running the superuser app. Unfortunately, it seemed that it was not as simple on the 70061.
As I am a novice, I followed the instructions blindly and read them through a number of times before attempting.
I followed a set of instructions which described downloading a zip file which contained adb for windows and some img and zip files to transfer to the sdcard.
I am using ubuntu, so I assumed that the adb which was installed along with android sdk would suffice.
I copied the required files to the root of the tablet's internal sd card and installed recovery via adb.
I unplugged the tablet and rebooted in recovery holding down volume-up while powering on.
When in recovery, the instructions told me to install superuser 3.1.3.zip from the sdcard but this file was not present.
When selecting 'reboot', the tablet kept rebooting to recovery and now seems to be stuck in a loop.
I hope that someone can help.
Factory Default reset?
How do you even get into the recovery menu. W/o I try, I get to the screen with the stupid robot laying down, and a ! inside a triangle showing. What buttons do you press to open recovery menu? On that page, no lists of stuff appear, and I want to reset the android tablet I used, also a TAC-70061, b/c it just keeps loading on the 3rd boot screen, and never gets passed it. Lame Denver product is not worth 2 cents. Apart from how annoyed I am, can you explain to me how to get into the factory reset and reset it/fix it?
Hi all,
Ok, so I have a weird problem with my Asus TF101 that for the life of me I can't seem to solve myself. Which is why I finally decided to ask for help.
To make a long story short: About two years ago I bought a used TF101 that I have been very happy with so far. And I definitely don't want to give it up, as it's been working fine until a few weeks ago. Then those boot loops (that everybody seems to be talking about) started and I was able to revive the device once by leaving it plugged off for a few days until the battery was empty (thus, I think, forcing a clearing of some kind of cache) and then re-booting it. Unfortunately, this does not seem to work anymore.
My TF101 has been rooted by the guy that owned it before. It features TWRP in version 2.2.1.4 and an older KatKiss ROM. Now, my situation is as follows:
Boot loops are preventing me from getting past the boot screen. I can thus not install or use any apps.
I can enter TWRP recovery mode and I could wipe the device, but I cannot find any ROM on the internal memory.
When connecting the TF101 to the computer (I'm using Linux Mint 17.3) it doesn't show up as disk. Only when unplugging it again, an error shows up on the Linux screen saying that the TF101 could not be connected. This is preventing me from loading a new ROM onto the device via a cable.
The device doesn't seem to recognize an SD card (32GB), no matter if formatted as FAT32 or as EXT3, with or without SWAP. So, in the TWRP file manager I cannot access an external SD card to load and flash a ROM.
When I enter "Mount" in the TWRP menu, I can't seem to switch to "Using external SD": When doing that I get an error "E:failed to mount /sdc (No such file or directory)" in the terminal window.
I have been reading forums up and down, but can't seem to find any helpful advice that applies in my case. I'm guessing the boot loop would disappear, if I could flash a new ROM, but I don't know how to put that on the device. Also, in case some of the problems are caused by version of TWRP that is installed, I would like to update that... but, again, I don't know how to get the new version on the device. I thought about entering APX mode, but holding Power and Vol+ simply turns my display black after a few seconds... no sounds, no beeps, nothing showing up on my desktop.
Any ideas? Pretty please?
Any help would be much appreciated.
Thanks in advance.
