Boot loop - How to get out - Barnes & Noble Nook Tablet

Was attempting a change when I pressed "n" while powering up. Now stuck in a fast boot loop where it gets to N screen then cycles again and again. Help!

nook version (8 or 16)
firmware (rom used before bootloop)
if you have it already rooted, and have installed CWM then re install the rom you were using
if you were using stock, their are instructions on how to fully wipe your device to stock (requires firmware download to SD-->reboot)

Already rooted, 16GB, had cm7 installed and has CWM, but, how do I get CWM up and running when it just keeps continuously cycling thru bootup? Tried holding down "n" and didn't work

Have you tried putting recovery on an SD card and see if it boot to that?

Enter CWM
hold n + Power together until force shut down
after power down,
hold power and QUICKLY hold the n again... (5 secs later, let go of the power but keep on holding the n until the CWM comes up)
format all the stuff, cache dalvic etc. and then reinstall the rom

No go. Pressing power and N together, counting to 5, releasing power, holding n - the "n" logo appears briefly, then the screen goes blank.
Do I have the sequence right?

SORRY
instructions modified
hold n + Power together until force shut down
after power down,
hold power and hold the n again at the same time... (5 secs later, let go of the power but keep on holding the n until the CWM comes up)
format all the stuff, cache dalvic etc. and then reinstall the rom
What assumption i made--> i am ASSUMING that CWM is installe ON the nook itself and not off some SD

Nope. Tried with and without sd card in (pretty sure I have CWM both internal and on card). All it seems capable of doing is powering on just long enough for "n"logo to come up for 2-3 seconds, then shuts down no matter what I try

Interesting
Reading through the post my question is:
What "change" were you doing?
This can shed light on what the problem might really be caused from

If you have CWM on a bootable SD card, power off the NT. Remove SD card, reinsert SD card. DO NOT POWER ON WITH POWER BUTTON. Plug in wall charger and let NT turn on by itself
Sent from my NT running CM10

All it does when I plug it in (following your instructions) is continue to cycle through the n logo process over and over again

i dont think your entering CWM correctly in my instructions, because that will ALWAYS work since it is seperate from the main Nook boot

What I'm doing:
(with card IN)
Holding [power and N down (same time), waiting 5 seconds, releasing power - CWM does not come up (screen goes dark)
(without card)
Same as above
What I was doing prior to this issue was - after installing Goo manager and downloading blaze.img file for TWRP),it says it installed correctly but didn't reboot to TWRP screen like supposed to. Followed instructions to boot it up by pressing power and N simultaneously, that's when bootloop started

im out of ideas...maybe try the unbrick method for complete reformat...

OK thanks - anyone else?

Are you sure your SD card is formatted as bootable?
Sent from my NT running CM10

I shouldn't assume anything anymore although that is how I got to CWM way back when needed. Lets assume it is not. I have me most recent backup on that card. Can I refresh CWM on that same card, keep my backup, and use it to boot up? If so, how?

My card has an clockworkmod folder which contains th backup I did a few days ago. It also has folders for all the apps I've installed. The version is pre 6.0 and I've read you need a later version to work with CM10, but I'm getting ahead of myself.
What should I do to get it to boot up into CWM? If I can get that working I assume I can reinstate from my backup to cm7 (where I was previously)

Make a bootable SD card with a different SD card using http://raywaldo.com/2012/05/root-nook-tablet-with-cwm-sdcard/ as a guide. Just use a newer CWM

If your NT is like mine, it will only boot off an SDcard from a power-off state and upon insertion of a powered USB cable.
[This of course assumes that your card has a bootable FAT32 partition (LBA and Active flags set) which contains the requisite files (u-boot.bin, MLO, boot.img and/or flashing_boot.img)].

[Q] Really Lost

I have a Viewsonic GTablet. I have used it very little and know nothing about rooting or ROM's or anything. I picked it up one day and turned it on and it's in a loop while booting...it goes from "viewsonic" to "Gtablet" to "TapNTap" then sticks there for several minutes then turns off. I have tried holding down the power and Vol. + and It comes in the upper left hand corner saying "Detect Recovery Key Pressed" and then "Booting recovery Kernal Image". Then the "unpacking box" appears...nothing happens but when I press the "HOME" button it says "Formatting MISC" and then "Rebooting" then the loop again. Called Tech support they laughed and said send it in...not sure about all that but would rather figure something out before doing that...thanks in advance...remember I am a NOVICE...so simple instructions please LOL
You need a data wipe/factory reset. Can be done from stock recovery. I recommend method I from the following thread...

Did that it came up with the first 2 "Detect Recovery Key Pressed" and "Booting Recovery Kernal Image" then to the "upacking box" for about 5 seconds then to the loop again. Still lost...thanks for trying to help any more suggestions?

Look for the links about installing clockworkmod. Once installed you'll need to try the data wipe and possibly repartition your internal storage. That will cause any data stored there to be lost.
tried all of them and the tablet will not recognize the SD card or being connected to the computer
A little more than tried all of them would be helpful...
Did you get CWM installed?
Were you able to wipe data?
Did you partition?
What was the result of each of those actions?
Is the tablet still looping?
Can you still get into recovery?
If not, what exactly is it doing when you turn it on?
No..I put that on the SD card and put the SD card in the tablet. Booted up and it goes through the same cycle. It will not even boot from the SD card. It never brings up a menu to cycle through with the Vol + or -....if I connect it through the USB it never recognizes it because it never comes out of the boot loop.
Thanks for all your help...I am really a novice with this thing
Well... It doesn't boot from the SD Card. Recovery looks at the SD Card to see if there is anything for it to do. Back to basics...
Install ClockworkMod: http://forum.xda-developers.com/showthread.php?t=865245
The first part of that post describes how to do it. Use the MicroSD card version which you will find at the bottom of the first post. You'll need to download it, extract it and put the recovery folder and update.zip at the root of your MicroSD card using your computer. Then put the MicroSD card in your tablet. Turn the tablet on while holding down the Volume Up key. You should boot into recovery and see the little box, arrow and progress bar. When it finishes you want to reboot it while holding down the Volume Up key again. That will get you into ClockworkMod (CWM).
From CWM main menu you can wipe data. Try that and see if it helps. If not then reboot while holding the Volume Up and go into CWM again. Select "Advanced" menu and you'll find the partitioning command. Select it and answer the two questions with 2048 and 0. This will erase everything stored on your tablet in the user storage space but should fix the problem.
Tried it
Tried it and this time it worked like......clockwork LOL...thanks so much...any more advice to have an awesome butt kicking machine?
Glad to hear it. Hang out around here for a bit and read up on the custom ROMs and stuff. You can turn these tablets into some pretty kick butt machines without too much effort. Just take your time and make sure you understand the process before you get started.

[Q] went from das bamf 1.4 to gingersense 2.1 now stuck in htc loop help

I made the change from das bamf 1.4 to gingersense2.1 and now I'm stuck in HTC loop, I can't recover or anything, I'm so bummed please help
Did you wipe through CWM? Are you on the correct radio version?
Boot into hboot and then restore from previous backup or reflash ROM. (Shut the phone down/Hold the Volume down/Then press the power button)
Similar thing happened to me, but not due to the Roms you mentioned. Here is how I was able to get out of the boot loop.
Before You Begin:
1. Perform the steps below at your own risk!
2. Make sure you have a USB micro SD Memory Card Reader (~$6)
3. Charge your phone's battery as best you can, or use a spare battery
4. Download Rom of choice to your computer
5. Do some research into removing the micro SD Card as needed
6. Don't Panic! (I Love to Say This!)
Here We Go:
A. Remove battery from phone
B. Remove SD Card
C. Insert SD Card into USB micro SD Card Reader
D. Plug micro SD Card Reader into USB port on computer
E. When prompted, select option to view folder contents
F. Rename Rom PG05IMG (Keep .zip extension - PG05IMG.zip)
G. Copy PG05IMG.zip onto root of SD Card
H. Eject micro SD Card Reader from computer
I. Install SD Card in phone and then install battery
J. Press and hold Volume Down & Power buttons until phone boots into recovery
K. PG05IMG.zip should be automatically recognized by recovery
L. When prompted, press (Not Hold) Volume Up button to start update
M. Wait for flash to complete (Be patient, get an ice cold Root Beer!)
N. When prompted, press (Not Hold) Power button to initiate reboot
O. Wait for phone to boot (Be patient, get another ice cold Root Beer!)
P. If all goes well your phone will live to fight another day!
Personally, I reset my phone after following this process. I then perform a wipe and flash the Rom a second time before setting up my phone. Some will say this is overkill though.
Try to boot into recovery (pull battery, hold volume down and power button). Wipe Cache then Wipe Dalvik Cache, then reboot and see.
i did all the steps from above EXCEPT trying to rename any ol rom, i did try to reflash the final rom from the rooting process, to the save results , stuck on the htc white screen loop. i was using das bamf ginger remix , had it working , but with no signal when i powerd phone down to reboot is when i got the loop, from what im reading there is no cure?????? ill try to reflash a different rom ,, but really need the link to put it back to stock to return to verizon, please help
Don't panic. Somebody here will be able to help you, and after you are done, you will not need to return your phone to Verizon. Renaming that file to PG05IMG.zip is important to get it to read in H boot. are you able to boot into recovery at all? and if so, do you have any other roms still saved on your sd card?
Also, how long are you waiting for the screen to change?
I can get into recovery for a second then loop starts all over again

You need to have a Rom on the root of your SD Card named PG05IMG.zip for recovery to provide an option to flash. As I mentioned before, I was stuck on the HTC screen and recovery would not work, but I was able to escape the boot loop by placing a renamed Rom on the SD Card. Try it, it works!

[Q] Problem Installing BSR on CM9

Recently i flashed the CM9 rom onto my Droid X2. Followed the instructions and everything installed correctly. Since it has been a couple of days and I have installed all my programs and got everything where i wanted it, i wanted to make a backup.
Soon i discovered that I didnt have System Recovery installed. SO i began looking into my SD card and i have two files,MOTODX2_Bootstrap_signed.apk. So i decided to install it, everything went fine but now my phone is stuck in a boot loop. It wont even boot into CM9.
Is there another BSR that i should be flashing instead of this one. Maybe the ReRecovery one? i know theres a [patched] BSR to install but i gave me the same problems.
Thanks EHB
Hi, for Cyanogenmod9 use the CM7 PATCHED BSR. It works just fine for me everyday. I'm kind of addicted to flashing ROMs for some reason and usually am on different ones multiple times a day. Always in BSR either restoring or backing up. The patched BSR for CM7 works just fine for me. For reference, in the app drawer it should say "CM7 System Recovery" not just System Recovery.
I'm not sure if it has been looked into by dev's yet or not, but the day CM9 was released I actually did flash the CM7 ReRecovery zip and I was able to boot to BSR from a powered off state just by plugging in. I wasn't sure if it was okay to use, so I installed a fresh CM9 without it. I don't know if this is 100% safe or if there would be any issues from using the ReRecovery zip. I would recommend just installing the patched CM7 apk and trying to use that.
Here's the link to the patched CM7 Recovery. Pulled straight from the CM7 thread
http://www.mediafire.com/?pzz4413k6wggcao
***^That BSR is an application. You download, install and run it on your phone. The ReRecovery is a flashable zip you can install once already inside of BSR allowing you to get into custom recovery say for example, if you're boot looping. ***
================================================
If you're still having bootloop issues, try this;
-Grab your ECOMOTO charger, plug into A/C power, pull battery, replace & plug into wall.
- Wait for the Motorola logo to disappear and the battery charging icon to appear (this can take several minutes)
-When you see the battery charging icon, unplug your phone and pull your battery.
-Reinstall the battery and hold the VOLUME DOWN key while powering on the device. Release the VOLUME DOWN button when it turns on.
You should now see "FASTBOOT" in white text above the Motorola logo.
-Press the volume down key several times until you see ANDROID RECOVERY.
-With ANDROID RECOVERY now showing where fasboot was, press the VOLUME UP button. It will tell you that it is starting android recovery mode.
This will take you to a screen that shows a picture of an android next to a triangle with an exclamation mark (!) inside of it.
-From that screen press both the VOLUME UP and VOLUME DOWN keys at the same time.
If you made it this far, you're now in the stock android recovery. Using the volume buttons, key down to Wipe Cache Partition then press the power button to select. You will be taken to a confirmation screen. Key down and select Yes. Wait for it to complete. After you wipe the cache try rebooting back into CM9. This will take slightly longer than usual as your cache has to rebuild itself. If you can boot back up successfully, click the link above. Download the patched CM7 Bootstrap Recovery and install it. If you don't know what to do from there, open the application "CM7 System Recovery" and click "Install Recovery" -- You will now be prompted to grant or deny it superuser permissions. Allow them. You will receive a message saying the install was a success! Click OK. Now plug your phone back into the wall outlet and hit "Recovery Mode" and your phone will boot into BSR! From there just go to backup and save it to your external SD card. You can find your backups later via the file explorer of your choice under /mnt/sdcard/clockworkmod/backup. Note: You can rename the file so you know which ROM is which, just don't add spaces to the file name or it will ruin your backup and you will not be able to restore it. NO SPACES!!!
FYI you will still see the Motorola logo immediately after it turns back on. It takes a minute or two to boot into custom recovery.
I've been through a lot of trial and error with the X2 and these steps have helped me plenty of times. Hopefully they do the same for you....Good luck.
Cyanogenmod all day
Thanks for the information.
I knew basically everything you said except for the "wipe cache partition". Why is this necessary? I know that it doesn't delete personal information but what does it wipe/delete?
Im going wait to do this tomorrow - my day off. Im just worried that its going do the same thing and ill have to reflash and start all over again.
Thanks again EHB
Wiping the cache partition clears any/all application data and common app components. It does not wipe apps themselves, rather the files that the app generates when used.
Wiping it is necessary because when core system components are changed, the resources used by the apps also (could) change. Having stale app data after a system change or tweak can cause problems, which is why it is best to clear it. It gets rebuilt as apps are used.

I'm afraid I'm in the same boat and am going through these steps to hopefully get back on the right track. When you say the battery charging icon can take several minutes... are you suggesting 3-5 minutes, or up to 30 minutes? Because... I'm at about 35 minutes right now and am getting pretty nervous.
just skip to this part, if you can
remove charger and battery
-Reinstall the battery and hold the VOLUME DOWN key while powering on the device. Release the VOLUME DOWN button when it turns on.

I am having a similar but different problem with the patched BSR. I had it running fine while using CM9 on my Droid X2, but now I am running MIUI, and when I install and attempt to get into the custom recovery, it seems like it attempts to load it, but does not. What I get is a jumbled screen that has the colors of the custom recovery, so I can tell it is attempting to come up, but something is going wrong. It shows that jumbled screen for a few seconds, then goes black and eventually just shuts down. I have tried EVERYTHING I can think of to fix this. I have tried a fresh download of the patched BSR, and even did a fresh SBF and reinstall of MIUI, but nothing fixes it. Any advice you have would be greatly appreciated. Thanks!
I would re flash sbf
if you have been using ezSBF
use rsd lite, vise versa, or try a different sbf version like 2.3.3 and take ota update
or see if someone could upload a nandroid backup

The odd thing is, if I restore to CM7 or CM9, then the patched BSR will work again. It seems it only goes bad with MIUI. Could the ROM somehow affect the BSR installation and/or function? I wouldn't think this is the case, as other are using the patched BSR with MIUI without trouble.

I was trying to flash the latest CWM recovery using the method from this post by nba1341.
Easiest way to install the latest CWM to internal memory (FOR 16GB USERS! Untested on 8gb):

usually boot from sd is done by having the NT off with the sdcard inside, and then plugging in the usb cable and it should boot from sd.
I did that several times. Nothing happens.

[Q] Re-installing CWM Recovery (or getting to it)

Guys,
I'm rooted, with MDK base, and THOUGHT I had a working version of CWM (maybe 6.0.2.3?)
I was in the process of getting ready to try out a new ROM; going through the usual motions, formatting system, data, cache, and for good measure, I finished with a Wipe Data/Factory Reset (which I believe just does the same things again).
The phone suddenly rebooted and froze at the samsung custom screen. When I try to get back to recovery, I can't (hold down up-vol and power; blue message appears and disappears quickly in upper left, and back to Samsung custom lock screen.
I'm stuck. In the past, I always got into recovery by rebooting with ROM Manager, so I haven't really had to use the power-on/ vol up method (thus it may never have worked).
I can get into download mode. So I'm thinking - assuming - that the first thing I should try is to Odin CWM. But I'm admittedly confused, because all of the posts that relate to installing CWM seem to be in the context of the rooting process, and assume you have the ability to place certain files in rooted directories (like loki), which I obviously can't b/c I can't boot.
1) Is re-flashing CWM the right approach ? If so, is there a .TAR file somewhere with just CWM? I can't find an Odin-flashable .tar. EDIT: I found one, but it's designated for i9505. Same thing?
2) If that's not the right approach (or I'm just an idiot and don't know how to get into a working recovery), please advise
Thanks!
Turn the phone off.
Hold volume up and press the power button until it vibrates.
When it vibrates let go of the power and stay holding volume up until you see the recovery splash.
I've found that sometimes continuing to hold the power button will cancel the call for recovery boot. Not sure why.
You can always Odin if that doesn't work.
And I don't know of an Odin package for vzw recovery.

EDIT: Cr*p. Not out of the woods yet. Now, when choosing 'Install from SD Card' I'm getting 'E: Can't mount /sdcard/'
I'll post this issue in a separate Q.
