[Q] CWM cold boot - Barnes & Noble Nook Tablet

Q: why do we not have a key combo to enter recovery CWM after its been flashed ?
Ok , retartar q here but first a bit of back story , i beefed my sd card , not sure how but its dead so i swapped for another sd card. im offshore i cant pop into a store im 200 miles in the gulf so, i have flashed the ten point MT to the tablet and the internal emmc is still stock , i was trying out 10.1 4.2.2. i like it and now i want to flash that to the tablet but i can not figure out how to get into clockworkmod , ive searched and searched yes ive used google , yes ive tried all sorts of combinations on the tablet from a COLD boot i dont have access to touch screen at the moment to app to soft boot into recovery is out for the moment,
i have CWM installed on the tablet and cant figure out how to get to it from a cold boot , any thoughts ?
once i get to that im going to flash 10.1 to internal emmc , i wasnt counting on my sd card to break....

The easiest way would be making a bootable cwm sd card.
I dont think the cwm recoveries for NT have a hardware combo trigger, but try one of the the usual combo (press and hold) - power+n , n+vol up, n+voldown while booting. one of them may trigger recovery mode. But I've never tried this so i cant say for sure.
Also, wrong section

If you have the option to burn a new card that would be best but maybe you don't if you're off shore.
I thing that holding power and n trigger a full reset so you probably want to avoid that. You could try pressing power, release it and then right away hold n. I doubt it will work but it's worth a try.

i have one of those rare ones that doesnt need a cable to boot but what ive noticed is that upon cold boot it will boot to emmc then on the next cold boot boot to sd then next is emmc then sd card so no idea what thats about but i never had an issue holding power then restarting to get to boot to sd card but this leaves me to believe my only other microsd card out here wont work cause its failed non stop to boot to that sd card i had an 8 gig in it and my only other one from my cell is a 32 gig and its not booting same class 4 too , diffrent manufacture both name brand though , i think im **** outta luck until i go home and get my stash of sd cards outta my laptop bag ...
i tried burning a recovery sd card , nothing same boot to emmc factory software ,
ive tried countless things but all failures to boot to sd card , i think i need a diffrent sd card and thats not gonna happen for bloody weeks

OK so following the instrutions for the make sd card boot of 10.1 WORKED! but now i want to install to emmc is there a way to install to emmc once booted to sd card ? some reason i could not get the install from sd to emmc version to work , i have very slow bandwidth out here it takes me 2-3 hours just to download a bloody image (ROM) so i have the 10.0 install to emmc rom and 10.1 boot to sd how can i make this work without needing another night to download the image ?
yes , internet sucks out here , im 200 miles out in the gulf ...

I always use one of those "readymade" CM10 images on an sd when installing internally. What I do is I hold "n" right after "power" to get into Cyanoboot menu. Once there I vboot into recovery (CWM) and from there I can flash the CM10 and gApps that I put on the card prior to booting.
Described step by step: http://forum.xda-developers.com/showpost.php?p=43871774&postcount=2
Edit: And on a totally not important note: Those NT's that don't need to be tethered to boot from sd can't be as rare as some people seem to think, because of the dozen or so that has passed through my hands only one has needed to be plugged in to boot off sd.

SUCCESS!!! i got the 10.1 4.2.2 sd card to work , i then used cynoboot to get into CWM on internal , took a min to figure out how to copy from computer to my sd card the rom 10.0 but once i got it somewhere i could access it on the tablet under internal CWM it flashed and im booting it now , hopefully its not boot looped ..

SD Booting Experiment, Testers Needed!

So we are all confused with the tablets that boot straight to SD from power button and others that boot from usb cable put in. Everyone wants to see the tablets boot straight to sd when they hit the power button.
As seen in the below video, I was able to turn a usb only boot tablet into an always boot to sd from power tablet by forcing my tablet to brick and then recovering it. this got me thinking... maybe Barnes and Noble isnt as inconsistent as I thought... maybe they made all tablets to boot from usb and something some of us have done caused them to now always boot without usb.
Video: http://www.youtube.com/watch?v=0HC9XL_9aXk
So, I need some tester. I am not responsible for the loss of your tablet, you do this at your own risk.
Requirements: You need to have an 8gb or 16gb nook tablet that can currently only boot to SD from usb. This means that with bootable sd in, you can not boot to sd by hitting the power button from an off state and you require the usb cable to be connected from an off state to boot to SD.
File you must download: We are going to test this with the CWM bootable SD cards I have made: File here: http://forum.xda-developers.com/showthread.php?t=1439630
FIRST Make the SD card and then make sure you cant boot to it from the power button, and then make sure that you can boot to it from the usb
Second Make sure you make a backup of your tablet, I am not going to tell you to do anything that will brick you, but I am not going to be responsible for lost data... or atleast not bricks that I dont know how to get out of
Stop testing at any point that you become successful
Third TEST 1 Perform an 8 failed boots
With the SD card in and the tablet off, I want you to hold the power button down until you see the black N appear and maybe a white screen and the tablet turn off. This is one failed boot. Do this 7 more times and then let it boot the 9th time and allow it to factory restore. Now test to see if you can boot to sd with power button, if not, test with usb.
Fourth TEST 2 Unrooter http://forum.xda-developers.com/showthread.php?t=1380235
Root your tablet, then install the unrooter app, and then run the unroot script from the app
Test power and usb boot again
Fifth Test 3 Brick (8gb only)
Install cm7 rom, should brick on bootup, then flash back your recovered rom that you should have made before you started all this crap. Then test boot again for power or usb.
Fifth Test 3 brick (16gb only- Warning, I have not tried this)
Install my recovery rom for the 8gb NT, I think it might brick, then restore back with the recovery you should have made before starting all this.
Sixth Test 4: CWM, after installing CM7, clear cache, factory restore and clear devlic. Then restore back to your recovery and test.
Make sure you post as soon as something becomes successful. Do not proceed if something started working.
Please report back in this thread your findings.
Sorry Albert, I just noticed this thread. I will get a hold of an 8gb nt this weekend that I'm fairly sure only boots with usb.

Albert - thank you for looking into this. Bless you if this can be resolved. Just a quick note about your post, however: I think there are several places you talk about "boot to usb" when you meant "boot to sd". I've made the same typo lots of times myself.
I am one of the people who can only boot with USB attached. I will be HAPPY to try this out as soon as I can.
So interesting thing here, my nook tablet behaves differently depending exactly how long I hold down the power button and the home button.
If I hold it down for ~1 second after the "boot flash" (screen flashes)
it will boot to the sd card
if I hold it down much longer and it either turns off, or reboots (or tries recovery)
an odd thing is if I turn off the power, let it power off completely, wait an hour and turn it back on, it almost always boots SD and then any further reboot boots to stock.

Is this after any of Albert's experiments or just as you have it now? What root method did you use? 8GB or 16GB?
Ok, so I managed to pick up the 8gb NT today. It has been previously rooted. Here are the results of TEST 1:
First try, I must have miscounted because on what I thought was the 9th time, it loaded normally, and did not try to factory restore.
On the second attempt, @ power-on no.5, CWM loaded.
Third attempt, CWM loaded @ power-on no.2
Forth attempt, CWM loaded @ power-on no.4
At no point was the usb lead attached. Also I was only using the power button, never touching 'n'.
Will I remove the card, do a factory restore and proceed to TEST 2?

16 GB root through the SD card, I've since done a complete factory restore from the 8 boot recovery partition and the behavior persists this way.
I haven't had a chance to mess with it, since my wife sold her nook which I used for reading books while I messed with mine...
I got a new 16GB class 4 card on which I've backed up my apps with TB. I hope I will have some time to do some tests in the next few days. I have a bootable 32GB card (SanDisk class 4) with CM7 alpha final on it that I'll use as my test card for booting.
My Tablet is a 16GB model, so I'll likely have to try the "brick" with the 8GB image of CM7.
los101, so I am confused, did it work with just powering it on to start? or just doing 8 failed boots got it to boot to sd with just power and not usb?
FWIW... Just got my wife a n 8GB Nook Tablet for our anniversary. I used my MacBook to image your root card from this thread:
http://forum.xda-developers.com/showthread.php?t=1439630
I imaged it to a 2GB Kingston card. No idea what class it is because I haven't tested it. Stuck it into the 8GB NT, booted it *without* the power cable and it boots to SD just fine.
I then stuck in the 32GB Sandisk class-4 card onto which I installed CM7 alpha final... and it booted to stock.
It would seem we still might have a card issue, not just an internal issue. Tried turning off the 8GB NT, ejected the 32GB card, re-inserted it, still booted to stock. Turned the tablet off, removed the 32GB card, replaced the 2GB card and it immediately booted into the CWM recovery tool.
I then rooted by applying the zip using CWM from the 2GB card. Rooted successfully and asked CWM to reboot. Tablet rebooted to the (rooted) stock. I turned off the Tablet, turned it back on with the 2GB card still inserted and it, again, booted immediately to the CWM menu.
ALL BOOTS (except from CWM menu) WERE DONE WITH JUST THE POWER BUTTON. No finagling with the "N" button required.
I don't know if this helps, Albert. I'll still plan on eventually testing on my 16GB model. Also, when I have a free moment, I'll see if the 2GB card boots on my 16GB NT. If it does, what I would find interesting is if there is a way to get cards in general to boot more reliably across the board.
Edit: BTW - the 32GB Sandisk does boot to CM7 using the power cable.
Edit 2: Yes, indeed, the 2GB CWM root utility card boots great on my 32GB tablet without using the power cable (just pressing power).

Booted off SD just by powering on. '8 failed boots' was not required.
You know, just had a thought. I can try writing the CWM root image to the 32GB Sandisk SD card to see if it truly is the card at fault or how the partitions are set up. I'll also expand the last partition to fill the entire card as a test.
Is there anything fundamentally different in how the boot partition is set up for your root image over the CM7 (external SD) image, Albert? I want to make sure my tests actually are valid for comparison's sake and that I'm not just making the proverbial comparison between two dissimilar fruits...
I have CM 7 and have tested booting on two NTs that I have. I also have 32GB, 16GB and 8GB SD cards (each created from the same image and then increasing the 4th partition to full capacity for the card), and each behaves the same as the other depending on which NT I use. One NT always boots directly to CM7 using any of the cards, the other does not. However, if I first tether the one that doesn't normally boot to CM7, and immediately remove the tether when the first screen comes on, the unit will boot to CM7 (as expected) but will the always boot to CM7 again without tethering (even after a reboot to NT mode, a shutdown and then a new power on) until the unit is charged. After a charge I then have to re-tether the NT once, removing the tether quickly at power on, and from then on tethering is not required (again, until the next charge) just like before.
This behavior is fully repeatable for me and has been checked over the course of several weeks. It's magic I'm sure.

I had trouble getting succulents dual boot setup to boot at all. Neither from power button nor usb cable. I finally got it to work by burning celticwebsolutions cm7 image to sd (which booted perfectly from the power button), and modifying it with MiniTool Partition Manager per succulents instructions. It worked perfectly. Now I have stock rooted 1.4.2 on emmc and cm7/cm9 on sd. See my description here.
Perhaps this is not the place for this oddity/question, but I am attempting to root my 16GB NT and it will not boot to SD by *any* method. Neither Power, nor Power+N work, and when I try USB method, it will boot to stock after about 2-3 minutes, whether I've left the cable plugged in or not. Ideas?

In my experience, if the NT cannot boot off an SD card with powered USB then the problem lies with that SD card's format and/or content. You would be better off researching & asking your question in the forum thread that covers the SD-card rooting method you're using.
I am using Albert's R3 SD card (4.6 I think) method, one I created from his video instructions not one received from Albert. But I did locate Albert's troubleshooting thread and will try reposting the issue there, thanks. Otherwise, I'd be happy to help with the experiment!

I too was not able to create a bootable R3 card, until I abandoned using PowerISO to assemble files for the R3 disk image -- see my post here re: the alternative method suggested by Albert.

can not install ics of any rom

hi everyone well last week ive tried many times over to install ics rom over my gingerbread and everytime this is what i get after i have completed followed the steps of how to upgrade to ics rom....when its trying to install the sd card can not be mounted...and repeats it many times over...so then i put phone into recovery so i can reboot...and it rebooted into the ics rom which i dont know how, but now my sd card is damaged and cant mount so i lose all my info no biggy....after reformatting the sd card, its ok...so i figure i would start it again...same thing.....i even did the steps but left the sd card out where you are suppose to and put back in when needed...still the same thing cant read sd card on install and after reboot sd card damaged need formatted...so i dont know what else to think except that i just cant simply get it flashed to the ics roms of any kind properly...if anyone can help thanks
Should be moved to q&a section. You will get help there.

Sounds like you need a new SD card. Some of the stock cards don't play well with MTD based ROMs. I would probably get a Class 10 microSD card (be careful if you get 32gb, there are known problems with some of them)
I bought http://www.amazon.com/AmazonBasics-microSDHC-Class-Memory-Adapter/dp/B0058GH4U0/ref=sr_1_12?ie=UTF8&qid=1335980268&sr=8-12 and have had no problems at all after!
You are flashing the THS build 2 first right? You have to flash that rom, then reboot to recovery by holding down the power button wile your in the OS and select the recovery option after that you'll be in a compatible version of CWM. Flash AOKP M5 from there.

[Q] Bricked nook tablet (boot video added)

My nook tablet is bricked
Turn on the tablet will see the screen will a big n
and nothing happen
I tried to boot from sdcard but it seem don't recognize the sdcard during boot
putting zip files on sdcard is not working
CWM sdcard and ubuntu sdcard also not working
cannot get into CWM and how can I fix it?
I spend over 5 hours but nothing work......
Sometimes the SD Card boot "only" works by plugging in the nook power cable.
I tried more than 50 times by plugging the power cable and still the same....
BTW thank you for answering, if you have any other method, once I can do it, I will try it....
Is the Nook store near by ?
Sad to say no...
I am from Hong Kong....
What SD card are you using, i.e. Class and brand.
The higher class cards do not work all that well for booting from. The Sandisk Class 4 card, any size I imagine, works well for booting off card.
Not sure if this is your problem, but trying a different card my be a good direction to go for a fix, if you can get into CWM it will help.
Also, what specifically did you do/try to get yourself to this point? Always helps to know how you broke it to be able to fix it.
I am using sandisk class sd card
This happen will I try to change back from CM9 with new kernel and TWRP to CWM and CM7.2
After flashing CM7.2 and CWM, it successfully boot for once and then get into this situation on next reboot
I tried ubuntu recovery, sdcard version CM7.2 and this, but nothing work....
It looks like you have a similar problem to this http://forum.xda-developers.com/showthread.php?p=27381972. I think, form skimming over the thread they were able to get into CWM from sdcard - after many attempts. If you can get to that point you should be able to get an adb connection where as you can work your way out of this. Just read the linked thread, it should point you in the right direction.
Good Luck
I tried more than 100 times still noting happen
But when plugging in the power cable and boot the tablet, the indicator keep orange light and not green as it is in that post...
more options
what sdcard version of CWM are you using? you should try with another sdcard just in case, the procedures for a succesful CWM sdcard are the following:
For Windows users:
- Power off your NT and remove sdcard
- Put your sdcard into a card reader (preferably)
- Format your sdcard with SDFormatter https://www.sdcard.org/downloads/formatter_3/eula_windows/ (recommended) or any other but not windows native.
- Download latest Win32DiskImage-binary.zip from https://launchpad.net/win32-image-writer/+download (v5.0 recommended)
- Unzip the file
- Run Win32DiskImage.exe - Right click "run as administrator"
- Click the folder button and navigate to select the .img file you just unzipped.
- Click on the disk drive letter label on the right, and choose the letter that corresponds to your SD card.
- Press Write. When it finishes, press Exit.
- Safely eject/remove your sdcard and put it back to your NT
- Plug your device to the a/c power or PC using the USB cable, let it power on by itself do not press any button.
WARNING: This will completely erase your microSD card. Be sure to back it up!

OK let me get in puter I have other options. Obviously something in the boot process is corrupted
Edit: back!
Please try the following:
1. Verify the md5sum the ROM(s) you want to install just to make sure is not corrupted
2. Follow the instructions i posted in here to flash another CWM to discard CWM being part of the problem. Now as you already have the CWM sdcard you just need to add 8gb-16gb_cwm_internal.zip to the sdcard then boot again into CWM sdcard and flash that package
3. After that remove your sdcard and select reboot system now from the CWM menu, if your device boots fine then Congrats, if not then read the options below:
4. Read and try this. If no go, goto #5:
5. Read and try this

Right i forgot to add that @meghd00t's cwm sdcard already contain the 2 files (tools) that @soshite was talking about , so basically you just need the cwm sdcard, my partition images and adb working.
BTW what happened with option 2-3?

after trying option 6, the tablet now can boot into internal CWM
But after I flash CM7, it still keep booting into CWM rather than CM7....
Thanks for all, I can now get into the stock 1.4.0
I flash the flash-restore-stock.zip from here in CWM
and then using acclaim_update.zip to restore the tablet back to 1.4.0
I guest I may change the boot data and get mess up with it
Finally, thanks again for all help:laugh:
Yeah, for everyone else out there:
You must have stock recovery in order for the acclaim_update.zip to work.

[Q] Nook Tablet 8GB Dead. need help figuring it out.

I have a Nook Tablet 8GB that wont boot, just hangs on the 'N' logo.
I have been going though every suggested nook tablet "bricked" and "dead" forum post i can find. most are for the 16gb model.
I can get the CWM_NT to boot from external SD card, but it hangs at the "tapped box" logo.
I can get the cyan boot loader to work, and i try to load CWM "recovery.img" and the TWRP "altboot.img" from SD card, and they seem to load, but the screen gets all pixel filled and hangs, wont boot into any recovery from the SD card.
I was unable to get ADB to load in windows, and im not sure how to get that working in ubuntu.
Im looking for help to get the stock nook software working on the internal SD. I may need to reformat the internal partitions, and im willing to try everything.
anyone who can help me, and any questions i can answer for you please let me know i could really use your help.

I suggest using an SDC boot instead of internal ROM, especially if you don't know what you're doing.
Head over to goo.im for succulent builds. Download the SDC image for cm10. Once you flash use whatever SDC ROM you want.
Thanks for the fast reply, i have tried that method, and the parted fix it recommends. but i cant seem to get ether to work. I flash my sd card with the repart.img and boot my nook tablet 8gb, but it wont do anything. i leave it alone for 20-30 minutes on a the N logo, that software install message never shows up.
i have android sdk installed, and try to adb push parted command as well, and it fails with device not found. i have the nook showing up as "acclaim" in device manager.
still bricked.

@jbrennan: as @datallboy suggested you should try to burn and run Succulent CM10.0 image (cm-10-20121231-NOOKTABLET-acclaim-HD-SDC-img posted at http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/) off SD card. If that does not boot successfully your NT is likely hosed hardware-wise, but if it does you can try the next step of recovering internal ROM.
Thanks again for the fast replies.
I can get the nook tablet 8GB to boot the SD card, and when i let it "boot" SDC normal, or pick recovery SDC, i get a screen that hangs like this picture i took attached.
is it hosed? or fixable?

That might be hardware related. The older versions of cyanoboot make a similar screen when booting anything. It only happens for a second then boots into the ROM or recovery.
It might not be able to boot into anything is all. So if it is hardware related I can't help much.
Could it be the partition table? i read that if that's damaged nothing will boot. is there a way to fix the partition table if SD card wont boot recovery?

Well if your boot data partition is damaged then it might not boot. Adam outlet total reflash might have helped it, but for some reason it only works on 16 GB tablet.
I don't know of any ways you could essentially rebuild your boot data partition. Maybe another me member might be able to help though.

[Q] nook is bricked, still response to root format

hello guys,
i am a new android user and it is second time for me to root/flash room, my nook tablet was rooted and when i tried to flash cm 10.2, tablet won't boot from sd card, so i press n + power bottom(as someone said it can help tablet go to cwm recovery 6.0) i believe i hold 10-15 second, and i accidentally replease one of the bottom, n or power, i am not sure.. so my nook become as brick. every time i turn it on, it says i need to reboot again, if doesn't work i need to contact to nook customer service.
now, i have used two method so far, ubantu and cwm recovery, they seem not working at all(the tablet won't let me in to cmw v6.x when it was not bricked),and i tried the last one and only one that was use repary.img to recover(which is newest method in 2012,i am not sure if there a way way other than this) repart.img won't unzipped on my computer, my computer is win7 64 bit,the zip said,"unexpected ending of this archive"
what that mean?it means i am only one cannot unzipped the file in that thread.
by the way, i can still go to cwm 5.0 for my root-format sd card, but not the recovery sd card or anything else, HELP!!! it has been whole day!

Hi,
you need a clean copy of the repart.image.
http://d-h.st/5vJ
instruction thread here: http://forum.xda-developers.com/showthread.php?t=1663836
the repart.img sd card has been the most dependable way for me to reset any nook tablet , 8 or 16gb to stock.
I'd say get the latest copy of the img file, and burn it to a CLASS 4 Sandisk card
my experience is higher or lower class cards are often not as good for booting from NOOK tablets
if you erased the /system folder accidentally and di not reinstall an operating system, then the tablet will try to boot into recovery
if you erased the /factory partition accidentally, then even with a good recovery partition, the recovery will fail

sorry to hear that.
I have a similiar tablet, something has triggered the flash ram to not accept any writes

I have seen the problem on other devices (gps's) , but only once on 100 NOOK tablets
