[Nook HD, HD+ Q&A, Help & Troubleshooting] warrenia:
Thank you for useful information in this post. I have a similar problem with a Nook HD+ 16Gb

I flashed cm-10.2-20131011-NIGHTLY-ovation.zip using CWM. After zip was written the machine rebooted and continued to boot into CWM (sdcard was unplugged).

The log file shows

net.bt.name=Android
net.change=net.bt.name
dalvik.vm.stack-trace-file=/data/anr/traces.txt
init.svc.ueventd=running
init.svc.recovery=running
service.adb.root=1
init.svc.adbd=running

I: Checking for extendedcommand...
I:Skipping execution of extendedcommand. file not found...
I:Can't format unknown volume: /external_sd
I:Can't partition non-vfat: datamedia

I can boot from sdcard and flash both CWM and TWRP to the device. I can remove the sdcard and the machine will boot to CWM and/or TWRP.

I don't think I have emmc bug as I can connect using adb.

I can run parted. I can mount and write to all partitions.

At one stage I did format /bootdata However, I followed the suggestion to flash stock rom stock-ovation-2.1.0.zip

This actually did rewrite files to the /bootdata partion

/bootdata # ls -lt
-rwxrwxrwx 1 root root 1088 Oct 15 17:15 BCB
-rwxrwxrwx 1 root root 4 Oct 15 17:15 BootCnt

However, if I flash stock, CM nightly, CM stable CWM says successful

But when I browse the logs, I still get the error I:Can't partition non-vfat: datamedia in the log file. The HD+ still keeps booting in to CWM.

I would be very grateful for suggestions.

I guess I can run CM from external sdcard.

I'm not having very much luck getting traffic on my post, and this one seems active, so I'll try here. Below is my problem:

Im having the below bolded issue and at my wits end. I was running Slimbean 4.3 for a couple of weeks with no issues. Whatever happened, happened while the device was running, and not in recovery mode because I was at work at the time, and my daughters told me the nook just turned off. They dont do or know anything about recovery. I can get to recovery, but when I attempt to boot, I cannot get past the Cyanoboot screen. When I do get to recovery, this is what I see:

E: Can't mount/cache/recovery/command

E: Can't mount/cache/recovery/log

E: Can't open /cache/recovery/log

E: Can't mount/cache/recovery/last_log

E: Can't open/cache/recovery/last_log

Needless to say, none of my nandroid saves will load(stock 2.1, CM10.1). Leapinlar, I made an SD boot of your stock 2.1.0 image (using the older winmanager method because im more familiar with it), and it begin to flash, then get stuck halfway and shutdown. Then I reboot and Im stuck at the same CWM bootscreen, which continues to loop. I also tried the flashing the 2.1.1 with the same results. I've tried this serveral times with the same results. I followed your instructions in your CWM thread to the letter. What can I do?

Someone suggested I connect to the PC via USB and the nook will reset to factory, but that didnt work for me.

ps-is there a way i can check for the emmc bug while Im stuck in recovery?
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
Try just flashing my stock recovery from my HD/HD+ CWM thread and then interrupt the boot 8 times in a row and it should reset and install the factory ROM.

Thank you leapinlar

Dear leapinlar,

Thank you so much. You are truly amazing. Thank you for your ZIP file. I flashed it, machine reboots and hey presto it's boot CM10 again.

What a wonderful experience on XDA developers forum, and all due to you. You spent time and effort making me a recovery file. You have made my month, I don't have a bricked device, and you have restored my faith in humanity with your help and patience.

Much respect to you.
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
Yes, I mean that item. But only flash the stock recovery from that item. We will know more about whether your emmc is messed up after flashing that and trying the 8 failed boot procedure.
[Nook HD, HD+ Q&A, Help & Troubleshooting] sadmaker:
OK here's what is happening. I flashed the stock recovery. I experienced the following:

1st reboot: showed nook screen, then immediately went to cyanoboot, where it hung. I powered off

2nd reboot: showed nook screen, then the 1st of 8 errors (screen). i powered off

3rd reboot: showed nook screen, then immediately went to cyanoboot, where it hung. I powered off

4th and every ensuing reboot: shows the nook screen, with a blue bar below it that fills up as it goes along from left to right (0%-100%). every single time, its gets hung up on 99%, then reboots and starts this process over again. This is the cycle: boot to nook screen, then blue bar until it fills to 99%, reboot.
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
It is trying to install the stock ROM and as part of that it tries to populate the other partitions as the last few steps. And that is where it is failing. This tells me something is wrong with your other partitions. Sounds like it is time for a warranty exchange. All traces of the non stock ROM should be gone now.
[Nook HD, HD+ Q&A, Help & Troubleshooting] sadmaker:
Thanks leapinlar,

I didn't previously want to get a warranty exchange, because every time it the nook booted up, it displayed the cyanoboot screen. Now there's no evidence of tampering. My nook isnt fixed, but with the help of your files, I can exchange it without any worries. Thanks again.

[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
To wipe your media files you need to wipe 'data and datamedia' in the mounts and storage menu.

And to get your /bootdata files back, go to my HD/HD+ CWM thread and flash the plain stock ROM from item 6.

And your serial number is on the box it came and is also on the flap covering the micro SD slot.

CM 10.1.3 can't reboot

I have few issues with my nook hd+ running CM 10.1.3.

I installed CRM, CM10.1.3 and gapps.

My tablet booted fine the first time. But when i select reboot option, it starts the reboot cycle but gets stock on the circle animation. I have to turn off and reboot into recovery or bootloader for it to reboot. I am not sure why it doesn't reboot normally when i choose reboot.

Another issue i see is that it only shows i have 768 MB memory on the device. I thought it had more than 1 gb.

I have issue with alarm clock. When alarm goes off in the morning. The screen takes a while to show up..can't turn off or snooze the alarm for few seconds.

Any guidence on these issues is greatly appreciated.

Thanks

I don't know about the rest of the items, but the 768 MB is correct. The remainder of the memory is reserved for hardware use such as video memory.

leapinlar,

Thanks for this. Somehow when installing the latest LiquidSmooth ROM I "boinked" my NookHD+ 16GB. I did the usual factory wipe, install zip from external SD card as usual and then all of the sudden all it would do is boot into CWM not matter what I did or what ROMs I tried to flash. I downloaded your "NookHDplus-factory-2.1.1-plain-stock" zip and got it back booting into stock Nook firmware. From there I'm in the process of re-installing CWM and installing ROMs again.

Do you have any idea why these issues are occurring where Nooks are getting stuck in CWM? Is it due to user flashing error or just something that might happen randomly with the NookHD+? I just want to try to avoid this in the future if possible. Donation sent.

smithmal
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
It is getting stuck in CWM because either the boot.img or /bootdata are getting corrupted during the flash. I don't know why that happens unless the flash process is stopping before completion. But usually flashing the stock zip will fix it.
[Nook HD, HD+ Q&A, Help & Troubleshooting] goingup:
I am in need of help. I took my brother in laws Nook HD+ that had an N2A card mod. I was attempting to remove the N2A card and install CM10.2 to the emmc. I did something wrong and I am now getting to the nook boot logo and it goes black and goes back to the nook logo and repeats. I can get into CWM but it see no files and everything I have tried does not get me to stock or CM.

Method of what I did.

Unistalled N2A card.

Rebooted into Nook and then shutdown system.

Set up a 32gb Sandisk class 4 card with sdformatter

Then used win32diskimager to burn emmc-cwm-early2.1 to card

Then copied to card cm-10.2-20131108-UNOFFICIAL-ovation.zip, gapps-jb-20130813-signed.zip, cwm-recovery-ovation-3.zip

From shut down state I installed the sdcard and turned on unit.

It booted to CWM and I choose to wipe data/cache

Then choose cwm-recovery-ovation-3.zip, then installed cm-10.2-20131108-UNOFFICIAL-ovation.zip, then installed gapps-jb-20130813-signed.zip

then backed up to wipe data/cache

then removed sdcard.

then backed up to main menu

and backed up to far and it rebooted

from there I get to nook screen and black screen and it repeats until it goes to CWM but I'm unable to after 4 hours get any method to work.

Please help me.
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
I follow you till the last line. There you say it boots to the nook logo and goes black until it boots to CWM. Do you mean it repeats the trying to boot several times (like 8) then boots to CWM? If that is what you meant, I know what is happening and I have a fix for you.

During your installation something glitched and it did not install the CM zip properly so it cannot finish its boot. Now it is attempting to do the 8 failed boot reset. But it needs the stock recovery to be still installed for that to work. And you replaced the stock recovery with CWM.

The fix is to go to my HD/HD+ CWM thread linked in my signature and go to item 6 there. Download one of my plain stock zips and flash that with your CWM SD. That will put stock back on internal memory so you can start over with your procedure. Hopefully it will work this time.

similar problem with nook hd+

Hi!

I have a nook hd+, and unfortunately, I don't really know what it went through.

I know it had a Cyanogen that was working entirely from the SD card, and then someone done something to it, and he can't even tell me what were the steps (it took some time until this unit reached me).

The situation right now is that I can't boot without and SD (black screen, no reaction) but I can consistently boot from SD with whatever CWM I put on it, but I can't install any zips from it, always getting the:

Can't mount /cache/recovery/log

etc.

Can't mount /sdcard/

Also can't manage to adb to it, but maye I didn't try for long enough.

Is there anything to be done about it?

I've tried 2-3 different CWM's, they all seem to work fine, but they all give me the same "Can't mount /sdcard" when I try to install zips. So no, as far as I understand, I can't install anything from an external SD.

Is this what you ment by installing?

/sdcard and an external SD may be different things depending on the version of CWM. There usually two options for selecting a zip. What I was asking is did you try both options?
