[Q] Nook HD, CM 10.1 w/ CWM earlyaccessv4 - How to diagnose mysterious reboot(s) - Nook HD, HD+ Q&A, Help & Troubleshooting

Hi All,
I have a Nook HD, recently purchased and then updated to BN 2.0.6 firmware during the BN registration process. I used the sdcard-cwm-early5.img.gz as referenced in Verygreen's post here to create a bootable CWM SD. I then installed the CM 10.1 build posted in thread by Bokbokban here. Finally, I installed latest gapps from goo.im. All seems to be pretty good, excepting that sometimes, seemingly randomly, the device will reboot itself, at which time it bypasses the SD during boot and goes straight for the stock BN rom on the emmc.
Any ideas on how to proceed? I haven't seen a pattern in the reboots yet, so I am not sure what may or may not be causing them. While I'm not exactly a newb with all that is involved with rooting/flashing various android devices (I own 5 of them), I could use some guidance on how to troubleshoot or diagnose problems like this.

I am confused. You used an HD+ image from verygreen and an HD ROM from bokbokan. How did you make that work? They should not have worked.
But if you really only used HD files, the reboot problem is probably the brand and class of the SD you used. It needs to be SanDisk class 4. We have that problem a lot on the HD+. It is cause by a kernel panic when trying to write to SD.
The solution is to get a better SD or use bokbokan's new Hybrid SD setup that puts /data on internal memory so SD speed does not matter.

Thanks for your prompt reply. To be clearer, I did not use the HD+ image, but I did use the CWM image Verygreen posted, 'sdcard-cwm-early5.img.gz', as that version supported using CWM to read .zip's from /emmc (in other words, those that were downloaded via BN stock browser).
At the risk of sounding like I am second-guessing you, I think it's worth noting that I had no trouble with many things related to writing to the SD card: writing the CWM image, booting into CWM from the SD, writing the CM10.1 image onto the card, booting from the 10.1 rom, etc... So if it is, as you say, the card having write issues and causing a kernel panic, I'm wondering how I can prove that. I will check the kernel logs when I get home.
I'm using a Sandisk 'ultra' class 10 16gb... I get that 'class 10' generally means 'crappy for small random write requests', but I've had good luck with this particular card on other platforms that are sensitive to consistency of write speeds (G2, Nook Color). However, I'll try a class-4 Sandisk per your suggestion.
Follow-up question: I can't seem to find a solid guide that shows how to install to emmc... is that a new frontier for this device? Is it just that nobody has bothered, or is there a problem with original bootloader supporting that?

The internal bootloader is locked down pretty good. Some day someone will be able to break it, but for now no one has.

[Q] Full Android HD+ As Yet???

As an original Nook Color owner from its first day availability, I am now ready to make the leap to the HD+. My primary reason for this is the 8.9 inch screen which emulates "trade paperback" size which has always been my reading goal along with enhanced video.
I have put my NC through numerous iterations over the last two years plus and finally did a full conversion to Android 4.1 a few months ago bidding a permanent farewell to any remaining vestige of the BN software. As the final remaining issue for me was "reading in store" which I no longer need, it was not a difficult decision.
In perusing this forum, I appear to have run afoul of trying to determine if there is a currently viable track for complete conversion of the HD+ eMMc as I simply do not need or want the BN interface. I know full well there are rooted, sdcard, and "hybrid" variations well explained in this forum but simply cannot find or continue to overlook any mention/instruction for full internal conversion as an option.
Am I simply overlooking that info or are we not yet there? If that goal has not yet been obtained, what would be my closest non sdcard option?
I have nothing but accolades and praise for those providing us with the fruits of their efforts. My multiple and varied experiences with my NC provided a truly fascinating experinece and learning curve starting with basic rooting up through several dual boot variations and now in eMMc Jelly Bean and all of its remarkably functional glory! It is clearly continuing with the HD and the "+" and I wish to express my deepest thanks for those continuing efforts in advance.
Any reasoned advice, suggestions, and/or direction would be appreciated.
As yet there is no full replacement of the emmc. The boot loader lock that even checks system makes it very hard.

Verygreenhas said he believes it is possible but not on his priority list, see his CM10 thread. We don't have many developers working it yet. And being CM working properly, kernels, etc are priorities now.

I too came from the Nook Color and have enjoyed the versatility of that device. Unfortunately B&N has locked down this device to make it more difficult to modify it. Your only two choices now is to modify stock with my CWM zips or opt for running CM10/CM10.1 from SD. You can get my CWM zips from my HD/HD+ CWM thread linked in my signature.

Get the HD+ and put cm10 via sdcard on it. If you use the right sdcsard (class 4? someone will correct me if I'm wrong) and dont look back. I came from the nook color 10.1 emmc myself. I know how soul crushing it was on there. Lag, reboots, lag, poor display, lag. Did I mention lag? I'd like an emmc too, but seriously you won't notice any difference. Its an amazing tablet with cm10 on it.

I have also had the Nook Color and the Nook Tablet.. the Nook HD/HD+ are awesome. I have always choose to ditch the stock B&N expereince. Currently booting CM10.1 from mircoSD on my NookHD, thanks to some awesome work by others, and its honestly great! maybe a few tiny little lags every now and then, but nothing close to a deal breaker. And its still early... so it can only get better from here. Going HD or HD+, you won't be dissapointed.
Actually this is strange that we dont have still bootloader lock hack. All tech things that i seen on xda forum are ulocked. And now some BN can lock it
I want help but i dont have knowledge for this stage. And with other words i need it too (run custom rom from emmc)..

Thanks to all for your comments, updates, and suggestions. I opted to take the "easy way out" this time around and d/l n2a's $19.99 version for the HD+ and installed it on a 32 GB card. Oddly enough, could not get it to run on a new Sandisk Class 10 but it ran on an older class 4 or 6 card that I had used for converted film storage with my NC. Any idea why that happened?
BTW, when formatting a card for the HD+ should we use FAT32 or NTSC?
It is great to have a full JB interface back!
Not at all enamored of the current BN interface which I hope now to leave alone and eventually replace when full eMMc access is achieved. If JB could be made "ready for prime time" on the NC, then I am sure that it is just a matter of time until one of you has a full blown "Eureka" moment and shows the way to a full and total conversion of the HD+.
Will keep you all up-to-date regarding my experiences with the N2A setup.

Actually i need run it internally because i have 12 Nook HD+ and clients who use these just may pull out SD (maybe steal SD too). All restrictions which one i made on ROm for user side is not working anymore.
Seems i need directly constact with Verygreen.
Thanks about sharing information.

Not sure what the above direction has to do with which format (FAT32/NTSC) is best for SDcard use in the HD+ for either simple storage or alternate OS.

This quote at this thread is about SD card formating:
For first time install only (you will need 4G or bigger sdcard, smaller ones are not supported and not tested):
gunzip cwm image and write it to your sdcard (entire sdcard not just one partition of it), use either dd on Linux/MacOS or Win32 Image Writer for those impaired by Windows.

Not all cards are created equal. The recommended card for running a ROM is SanDisk class 4. Others may or may not work well.
And it does not matter what format you had on the card originally before you burned the image to the card. It gets overwritten.
But for using an SD with stock, the card should be formatted Fat32 or ExFat. NTSC does not work.

Nook HD+: bootable SD after 2.1.1?

I have a new Nook HD+ on the way, I plan to register it and then install CM 10.1, but I'm concerned I saw in another thread that someone wasn't able to boot off an SD and the update automatically installed. Can anyone confirm they were able to still boot of an SD card after installing 2.1.1?
I was able to boot off a Transcend Class 10 SD card after installing the 2.1.1 update.
Some HD/HD+ units reportedly have difficulty booting off SD card, see http://forum.xda-developers.com/showthread.php?t=2288688. The problem has nothing do with the stock ROM, new or old.
Ok, thanks. Should have it today and will go ahead as planned. Just concerned me it was a brand new update and I'd only seen the negative response, but it sounds like it should be good.

My HD+ would not boot with a 4gb card or a 2gb card, I tried it at least 10 times apiece, however I did get it to boot with a SanDisk TransFlash 256 MB with just the boot image files and CWM.
It boots to the 256MB card first try everytime. So as soon as CWM loads I swapped the 256 for the 2gb and did a stock backup, rooted and installed CM.

It can be hard to get the SD to boot sometimes. In particular try the one where you hold the SD in.

I am tempted to dispute this. I had a brand-new HD+ with stock firmware v2.0.4 which consistently (and always at first attempt) booted from sd card (Kingston 4GB, cl 4).
After upgrading to stock firmware v2.1.1, but with no other changes, it wouldn't boot once in 50+ attempts. The sd card was unchanged, the HD+ hardware was the same, so this behaviour would seem to point to the firmware change as the culprit, doesn't it?

It does, but booting is controlled by the hardware chip firmware. There is no way for b&n to change that remotely.
A way to test your theory is to do an 8 failed boot with stock recovery installed and go back to 2.0.4. Then see if your booting trouble goes away.
Edit: If that is really the case, the solution is to revert to 2.0.4 and immediately upgrade to CM. Then it should boot SDs ok.

My HD+, which originally came with 2.0.4 and got immediately auto-updated to 2.1.0 and then later to 2.1.1, (luckily) has not had any problem booting off SD.
The boot-device selection process is controlled by the hardware configuration and bootstrap code in ROM (this is the device's real ROM, as opposed to the Android OS software that is commonly but incorrectly referred to as "ROM"); see http://omappedia.org/wiki/Bootloader_Project for an overview of the boot process, and more gory details can be found in http://www.ti.com/lit/ug/swpu270s/swpu270s.pdf.
Have you re-checked "bootability" of the boot partition of your SD card, or tried a freshly burned SD boot image? I have had a few instances of Recovery or ROM SD cards rendered un-bootable after the stock ROM created files/folders on them.

As I wrote in my first post, the sd card (which booted properly with v2.0.4) was unchanged. I deleted all stuff the HD+ had put on it (a bunch of empty directories, if I recall correctly) and it had only the 5 CWM boot files and 2 zips I wanted to install. To the best of my knowledge the sd card was unchanged.
Never mind, it's probably one of those things...

As he said earlier though, the fact that 2.1.1 wrote to it at all may have done something to the SD.

[Q] hd+ messed up, endless restart loop

Hi all,
please help me on this, please.
I think my hd+ was messed up. I remember at first I had CWM boot environment. but when I was flashing NookHDplus-factory-2.20-plain-stock.zip, it crashed. I didn't realize the emmc structure might be lost, I restart and flashed the twrp_recovery_ovation_4.zip into the machine(I heard from somewhere else it might be helpful). but now it is even worse.
I have tried 3 bootable microSD card(1. pny 4G, class4, 2. kingston 8G, class4, 3. sandisk 4G, class2) 1. is imaged with emmc-cwm-early3.1.img; 2. is imaged with nookHDplus-bootable-cWM-6028-for-stock-4GB-rev4-(05.11.13).zip. and 3 is formatted with SDformat & actived and with files from NookHDplus-bootable-CWM-6028-for stock-BOOTFILES-r4-(05.15.13).rar.
1)so without microSD card in slot, the hd+ did as follows(the power supplier is plugged in for indication):
green light turn on 4 second-->nook icon(with adobe reader statement) 2 second-->white cyanoboot(and blue universal bootloader) icon 4 second
2) with class 4 microSD card.-->loop
green light turn on 4 second-->nook icon(with adobe reader statement) 2 second-->white cyanoboot(and blue universal bootloader) icon 15 second.-->loop
3 with class 2 card.
green light turn on 4 second-->nook icon(with adobe reader statement) 2 second-->white cyanoboot(and blue universal bootloader) icon 30 second-->loop.
So it looks hd+ saw the microSD card, but still cannot enter the correct procedure.
Does anyone has any idea what I can do now? I was so frustrated...
Thank you so much in advance!
It might be that your emmc is bricked. All of the cards require that at least some of emmc is working. Verygreen made a noemmc CWM and ROM somewhere that I don't have a link for. Try searching the forum. Others have reported success with that in booting to CWM and getting a ROM working on SD.

Thank you very much! I would like to try it in the weekend. But I noticed in the discussions, that the OS on sdcard will also use some part of emmc, so if the emmc has errors in those part, the OS will not operate successfully, right?
By the way, is there any possibilities that you professionals make a kind of 'tool' microSD, that can automatically format and rebuild the file structures on a messed emmc and then copy/restore the stock OS to it without any manual input. Or even better, since the space of SD card is usually big enough, people can copy different OS zips into it, so that the tool card can let people to choose which OS to be installed after it automatically format and rebuild the file system structure on emmc.
Thanks again.

[Q] SD Install has bricked my HD+

I have an issue that seems to be similar to those suffered by a number of people. I'm just having difficulty understanding the cause of it, and the solution. I have a nook hd+ that no longer boots as a result of trying CM11 on an SD card.
I installed CM11 to an SD card (as I was nervous of altering my nook) using bokbokan's excellent instructions. Initially it seemed fine but this morning it was unexpectedly out of battery and will no longer boot.
The symptoms are similar to this: http://forum.xda-developers.com/showthread.php?t=2611769, this: http://forum.xda-developers.com/showthread.php?t=2736347 and this: http://forum.xda-developers.com/showthread.php?t=2649061&page=2 except that the posters there had previously replaced the stock software and overwritten the emmc.
When the SD is in, it locks up on the Cyanoboot screen, when the SD card is out I only get to the black screen with 'Nook' on it and no further. It looks like the SD install has messed something up on the internal emmc. Hard resets and multiple failed boots don't appear to help.
I can occasionally (but not always) get it to reboot to CWM recovery by reinserting the card and holding down N and lock, but I get a lot of errors such as "E:Can't open /cache/recovery/last_log", "W:failed to mount /dev/block/platform/omap/omap_hsmmc.1/by-name/cache on /cache failed:No such file or directory" and "I:Can't partition non-vfat: /emmc (ext4)". When I go to 'Mounts and Storage' in CWM, I cannot mount anything (e.g. "Error mounting /boot!").
I chose to go down the SD card install route (using ) in order to avoid touching the stock install on the emmc, but now the whole thing is dead.
Reading other threads, it sounds like either:
1. The emmc is bricked due to some firmware bug. The impression I get from reading around is that CM11 was supposed to incorporate a workaround for the issue. If the emmc is the problem, I have to return the Nook and hope to get a working one.
2. The emmc has (somehow) become corrupted, I have to put a different version of CWM on my SDcard (so it will install to the EMMC rather than the SDcard, and because CM11 uses a different version), using the instructions here: http://forum.xda-developers.com/showthread.php?p=35811322 and then reinstall a stock rom to my emmc. I then have to reregister the Nook (not sure if this is essential) before being able to use my CM11 SDcard install again.
If it is the first problem, I would like to know how I can check to see if the emmc is indeed broken.
If it is the second, I would be grateful for any help in understanding how and why the SD install has messed up the emmc, and whether the steps above are likely to bring it back to life.
It sounds like your emmc is indeed bricked. I would go for the warranty exchange now. Just because you installed CM11 to SD does not mean it does not use emmc partitions. It still accesses and uses many of them (cache, rom, bootdata, /data/media, etc.). So there is opportunity for a brick. I would exchange it now while the cyanoboot logo does not show when booting without the SD.

Thanks to both for replying. I feared that was the case.
I'm a bit disappointed that the SD card install (generally the option for those who want to leave the nook untouched) can in fact ruin the machine.
I've contacted the Nook website and will see what happens.

Just take your device to a store. They will exchange on the spot once they verify your registration on their computer. Of course don't tell them you were running CM, even on SD.

Thanks, but there are no BN stores in the UK. They don't even sell the Nook directly from their uk website anymore. I have to post it to the Netherlands and see what happens.
So, after 2 months, and a lot of arguing with customer services, I have finally got a replacement Nook through the post.
I am still keen to try CM, but want to be really sure that my Nook doesn't get bricked again. Is there any way of checking whether an sd card install is likely to trigger an emmc failure on my new Nook?

The best way to avoid bricking by CM11 is to not try CM11. I run CM 10.1.3 and have heard of no one bricking when running that.

Nook HD not charging since CM11 install
This morning I installed the latest CM11 build (M11) on my daughter's Nook HD. Prior to that I was using the stock ROM with no issues. Since installing the ROM the tablet will not charge; rather than showing an orange light the device shows a green light whenever the charger is connected.
It seems possible that my cable has failed at the same time as performing the install, though a little unlikely.
Thank you for your help.
CM11 - TI OMAP drivers going to get updated?
As seen here:
http://forum.xda-developers.com/nook-hd/general/updated-ti-omap-video-driver-sluggish-t2912381
Just curious if we'll see these get rolled in...
Thanks for all the hard work!
I updated my Nook HD+ from CM 11 snapshot 10 to 11 OTA , now there is frequent automatic-touches or ghost-touches on the screen without me touching the screen. Any help?
Newbie Questions - B&N HD+
Hi - i am going to flash my B&N HD+ for the first time. i have been reading the forums and instructions and have few questions.
i want to do this without SD card (i can go buy one but i if not needed, i prefer not to use it). is this possible? in the EMMC thread, i still see that the SD card must be used for the flashing/booting. so essentially, to flash CWM 6046, is it possible to not use SD card? and if so, can someone tell me how to do that?
Thanks

No, you must use an SD. There is no other way. And I suggest you use the dummies guide linked in my signature.

NookHDVolumeAdjuster for CM11 or CM10.2 ?
Is there a version of NookHDVolumeAdjuster that runs under CM11 or CM10.2 ? I am using version 1.0 under CM10.1.3. When I tried CM10.2, the sliders were all stuck at the far left. I need the sound higher volume, so I can't upgrade to CM10.2 or CM11. thanks.
Image Links?
Links to the intial sdcard image and recovery image in the original "[Q&A][Nook HD/HD+] EMMC CM11 install - updated 08/17" post are broken (nook.rootshell.ru appears down, from my perspective). Are these available elsewhere?
Thanks.

You can go to the dummies guide linked in my signature. In post 7 of that thread is everything you need for running CM11 on the HD/HD+.

Nook HD plus and Gapps error status 6
Good morning,
I was working on flashing my nook last night with
cwm-recovery-ovation-6.zip
cm-20141224-NIGHTLY-ovation.zip
I have tried many different versions of stock, modular-full, modular-mini and gets a status code 6, I have successfully flashed gapps-kk-20140606-signed, but when I try to use it, the playstore just hangs like it is loading. Can someone advise the steps I need to take to successfully install a working version of gapps?
I have tried factory wiping several times and flashing the various versions of GAPPS.
Thanks in advance for any assistance that you provide.
Jim

I'd suggest that you try resetting the Google Playstore app: go to Settings->Apps->Google Playstore, and do a "force stop" and "clear data" (after which you'll need to re-enter your Google (Gmail) account login/passwd).
CM11 M12 - Device Temperature
Hi all,
After staying around on CM10.2 for a long time due to a few issues with earlier snapshots of CM11, I've decided to upgrade to M12. Finding it runs great on everything I'm doing - definitely smoother performance. One thing I am concerned about is the temperature hike of my tablet, particularly when charged and running a game (in this instance, Terraria). Is anyone finding the back running quite hot? Can feel it on the screen and the left side of the device, but the temperature reading of 32C/90F doesn't seem that bad... it does feel worryingly hot though. Not sure if it's something on my end or a common thing with CM11, but I never had this on any other build.
As a sidenote - do the developers accept donations?
Audio stuttering in Rayman Jungle Run
I just did an SD card install of CM11 on a Nook HD+ and it's been working well (thanks!), except that I've noticed that the audio in Rayman Jungle Run and Rayman Fiesta Run tends to stutter / warble, making it unpleasant to listen to. Youtube and Great Big War Game sound are good. I'm using cm-11-20141129-UNOFFICIAL-ovation-sdcard.zip with its initial sdcard image for ovation (sdcard-cwm-early9.img) from the first post. The micro SD card is Samsung class 6 16GB.
Any ideas on how to fix this?

Well, what I did, is I found the thread here that describes how to put B&N's OS v2.2.0 on a bootable microSD card. Once I had that working (it's not like B&N is ever going to update the firmware), I did a backup of the Nook's internal storage, and then installed CM11 on the internal storage.
That should solve your performance issues.
Note: You mention an HD+, but then refer to "Ovation", which is the name for the HD, not the HD+. You may want to edit your message to clarify the situation.

Oops, since the files I used to install CM11 clearly say ovation.

Thanks for taking the time to reply. I would have done an internal install, but when I tried to backup the built-in firmware 2.2.0 using CWM 6.0.4.6 (from the OP), I got an error due to the /system partition being unmounted (I'm recalling this from memory; I hope I got it right). I tried using the mount option in CWM, but that failed too. I then said "screw it with the backup... I'll find another on the web", and then tried to do an emmc install of the latest milestone (M12) from the cyanogenmod download site (using SDCARD CWM-based 6.0.4.6 booted from SD... not internal memory), but the install failed with a "status 7" error (IIRC). I also tried using an earlier microSD image (sdcard-cwm-early7.1.img) and tried to install a backup of stock 2.2.0 firmware that I found from another thread here (thinking that maybe I had borked my own from an attempt at installing recovery CWM), but that finished too quickly (yet no errors), and on reboot it didn't appear to have overwritten my own stock firmware. After these efforts spanning a half dozen or so hours of reading, experimenting, etc., I was able to at least get the SD card install working, so I said screw it, I'll just use SD card. But I would really prefer an internal install as you suggest.
I wasn't able to get CWM to boot from internal memory, only SD card (Samsung 16gb class 6). I didn't try very hard though. Maybe this is the reason I can't do an emmc install or backup? Can you only backup internal memory after having booted from CWM recovery (on internal memory, not SD card)?
I was able to find a post somewhere that related the /system problem to rooting, but I never have rooted my Nook HD+ (manufactured Dec'12).
After reading more about the slow 4kB random write performance on most SD cards, I'm thinking of getting a Sandisk class 4 card, but I'd rather not go there if not necessary.
Thanks again.

It looks like you used the installation files meant for creating SD-based ROM image
See http://forum.xda-developers.com/showthread.php?t=2679899 or http://forum.xda-developers.com/showpost.php?p=42406126&postcount=7 for info/pointers on EMMC installation.

This worked! I now have an emmc install of cm11 M12 from the cyanogenmod site. Since I'm running Ubuntu GNU/Linux, not Windows, I replaced steps 1 to 3 in your instructions in the above link with (at terminal prompt, with microSD card inserted but unmounted):
gunzip emmc-cwm-early3.1.img.gz
sudo dd if=emmc-cwm-early3.1.img of=/dev/sdb
I then mounted the microSD card and copied (as root) the zip files as in your link, all with terminal. The unmounted /system partition error did not appear, and the M12 install went fine! When wiping I had an error related to sd-ext missing, but from some more searching I concluded that it was benign.
Thank you for helping me out. I was starting to give up before the help I've received here. I'm generally really pleased with the performance of cm11 on Nook HD+ so far. I'm not yet noticing much difference between emmc and sd-card installs, performance-wise.
Unfortunately, the earlier performance problem (sound stuttering/warbling in Rayman Jungle Run) is still there using this internal / emmc install vs. the earlier SD-based install of cm11, which suggests that the problem is in cm11 itself. On stock firmware (version 2.2.0 I believe when tested), Rayman Jungle Run ran fine (no sound problems at all). The sound problem may be a slowdown problem, but it's not severe.
