[Nook HD, HD+ General] erstwhile:
So I'm a little confused. Where exactly are people putting their sd card to write the image? Not in the nook because diskimage writer won't see that to write to. External or built in readers? The only way I've been able get diskimage to see the sd card to write to is when putting my sdcard in my cell phone, and turning on usb storage. but at the end of the write and copying files the phone itself and nook see the sd as damaged/errors. Is this viable or am I missing something obvious?
[Nook HD, HD+ General] Steve Tack:
Just wanted to give a big THANK YOU to e.mote for this guide! I'm an Android noob and was able to get CM10.1 installed without much fuss. I don't think I would have even attempted it without this thread.

---------- Post added at 11:28 AM ---------- Previous post was at 11:22 AM ----------

I was under the impression that you'd normally use an external card reader for that. I bought one just for installing CM10.1, since I didn't have one. I'm a new user, so I can't post a link, but I ordered a small $6 one from Amazon. I'd recommend one with a direct microSD slot so that you don't have to mess with an adapter.
[Nook HD, HD+ General] dawgpoundfan:
so if I can't get Win32DiskImager to write to this card I have to buy another?

I ask because I really don't want to go out and buy another one, I am limited on my time and resources as is, and going out to buy another SD card is not an option. Not a huge deal, I'd love to have Cyanogen instead of Nook's "version" of an OS...but sadly I am not able to go out and buy more cards.

every time I attempt to write it says it worked but when I eject and reinsert the sd card it Windows 7 wants to format it...rats.
[Nook HD, HD+ General] dpham00:
Which sd card so you have? SanDisk class 4 16gb or less seems to work the best
[Nook HD, HD+ General] dawgpoundfan:
Sandisk Ultra 32 gig

Just tried a class 4 16 gig no joy on that one (pulled from my son's tablet, he's not too happy right now, hehe)
[Nook HD, HD+ General] verygreen:
Did you forget to unpack the image before writing it? I imagine that would result in exactly this behavior.
[Nook HD, HD+ General] dawgpoundfan:
nope I did - 4912 is the size of the image - I hit write, choose that file and it disappears from the file directory eject and reinsert and it says would you like to format.
[Nook HD, HD+ General] verygreen:
And I also assume you are writing onto the whole device, and not onto the partition?
[Nook HD, HD+ General] leapinlar:
What do you mean, it disappears from the file directory? Are you putting the image file on the SD before you burn with win32diskimager? You should be putting the .img file on the PC and burn to the SD.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook HD, HD+ General] dawgpoundfan:
Sorry for confusion guys, just would love to get CM10.1 on this tablet. I downloaded the image, unzipped it, and then opened win32diskimager and hit "write" onto the root of the sdcard. as soon as it says write was successful the sd card dissapears for the explorer file tree and I can no longer access it from explorer. When I eject and reinsert the card it says I need to format the card.
[Nook HD, HD+ General] Figster07:
Hi ,

Thanks for the reply.

When you say use CWM - use the one that I already have as part of CM10.2?

And the factory reset and Wipe is within CWM?

I'm sorry - I am still learning all this!!

Cheers
[Nook HD, HD+ General] leapinlar:
No, do not use the one for CM10.2. Make a new bootable CWM SD from the files in the CM11 post. You do not need to do the step to backup stock. Then before the step to flash the new CM11 zips, do the wiping I recommended in my last post with that new CWM.
[Nook HD, HD+ General] Figster07:
Ah much clearer - thank you I think this all makes sense.

I shall try it and let you know how I get on!

Thanks for the help
[Nook HD, HD+ General] mogators1:
I just updated my HD+ to the latest nightly yesterday. I flashed the internal CWM from this thread, rebooted, then I did a factory reset, format system, and cleared dalvik cache. I then flashed the ROM and GAPPS. My location settings seem to be working now (weren't working with 10.2.1). I'll have to see if I can connect to other wifi's without rebooting when I get away from home as that wasn't working before either. I did have the screen flashing issue and turned off the overlay setting in the developer options and that seemed to clear it up. My wifi connection does not turn blue though as it used to. Seems to work, but I'm wondering why it doesn't change color and wonder what that means. Any ideas?
[Nook HD, HD+ General] Figster07:
Hey,

Just to advise everything worked and I was able to Install CM11 nightly...

Now running 4.4.4 :)

Thanks for your help
[Nook HD, HD+ General] tt c6:
Can someone please just post a link to a STICKY THREAD with the latest "idiot proof" step-by-step instructional to install Android (CyanogenMod) to the Nook HD+ ??????

All the threads I am finding are from 2013 and a search for "sticky" in this thread came up with nothing.

Thank you.
[Nook HD, HD+ General] leapinlar:
This thread is the latest and is up to date. Pay no attention to the original post date, it is updated as necessary. There is no sticky. Use the first post for CM10.1/CM10.2 and the link to the seventh post for CM11.
[Nook HD, HD+ General] tt c6:
Thank you for the quick response.

May I request that if this is the best, and most up to date, instructional guide thread for installing Android, it be made a sticky?

Also, as of 7/23/14, what is the recommended CM version? (CM11, etc)

Thank you.
[Nook HD, HD+ General] leapinlar:
This is the latest and most used guide. Only a moderator can make it a sticky. And I make no recommendation which version to use here. There are plenty of other threads dealing with that subject. This is just an install guide.
[Nook HD, HD+ General] WavyA70:
HD+ can't mount /system on cwm backup

I am getting a can't mount /system message when I try to back up at CWM screen. I have the Leapinlar? zip files installed to root stock.

I wanted to rty CM10.1.3 but wanted another backup first.

TIA

David
[Nook HD, HD+ General] leapinlar:
Are you following the guide in the first post? Which version of CWM are you using? And which device, HD or HD+?
[Nook HD, HD+ General] WavyA70:
-Yes as I am understanding them. I already had a SD card with CWM : NookHDplus-bootable-CWM-6028-for-stock-4GB-rev4-(05.15.13).img

-My Nook is a HD+

This before CM w/just rooted stock.

The backup starts but gives that message (can't mount /system) after the "Backing up system.." message.

Could it be the root??
[Nook HD, HD+ General] leapinlar:
It is not the root. You say you already had the SD with CWM. Are you sure it was not an old CWM SD that you had used for an SD install? That would cause those symptoms. In any case, start with making the SD fresh again with that image file you quoted.
[Nook HD, HD+ General] WavyA70:
Success

CM installed and running!!:o

Me bad! I thought I had 2 SD cards which were the same, WRONG. The one that did not work had CWM 6.0.32 and Two other directories that must have been added when I did the original rooting as you sugested.

Thanks much for all your efforts,

David
[Nook HD, HD+ General] tekpmb:
Which file should I download?

I'm very new to this kind of stuff. I installed CM10.2 on my HD+ and it GooglePlay crashes and the device is unstable. I must have downloaded/installed wrong version of one of the files.

I am trying to install CM11 now and reading leapinlar's guide for dummies. Guess I'm dumber than a dummy :laugh:

Which file should I download for "cm-11-####-ovation.zip (CM11) (the CM ROM zip)"? There are several nightly, stable, snapshot files. Is it OK to download the latest snapshot file (cm-11-20140708-SNAPSHOT-M8-ovation.zip) ?

I do not see a file similar to "cm-10.2.1-ovation.zip" for CM-11.

Thanks
[Nook HD, HD+ General] leapinlar:
CM10.2 is finished with development while CM11 is still going through development. Therefore CM10.2 only shows the stable (the "cm-10.2.1-ovation.zip" is the stable) and the last snapshot and CM11 has no stable, only nightlies and snapshots. Pick whichever CM11 you want, either the latest nightly or the latest snapshot.
[Nook HD, HD+ General] mooooor:
My new nook hd+ has been running incredibly sluggishly since installing Cyanogenmod about a week ago. Constant slowdown and app crashes - sometimes just bringing up the touchpad when browsing takes a few seconds. I'm not sure if this is a problem with CM or the device itself, but I'm pretty sure it's the latter. I've tried multiple versions of CM, 10.1, 10.2 and 11, and have similar problems with all of them. I'm not getting as much slow down on CM11, but trebuchet will periodically crash.

Does anyone know of a way to fix this? I've been googling the issue over the last few hours and have read that some nooks have a problem with the trim function, and that installing an app called lagfix can help, but I've also read that this only applies if you're using CM 10.1, as well as several reports about lagfix bricking nooks completely if not used properly (but not much info on how to use it properly)

I might just restore to stock, but I'm not sure if that will even help. I installed CM as soon as I got the device, and didn't test it on the stock os.
[Nook HD, HD+ General] leapinlar:
If is it a lag/trim issue, you will have the same symptoms with the stock OS.
[Nook HD, HD+ General] mooooor:
Bugger. Should I look at running lagfix in that case?

The only thing is I've read this is totally redundant on versions of CM above 10.2. I'm currently running CM11.
[Nook HD, HD+ General] leapinlar:
I am not going to advise users about lagfix. I agree with you that it is supposed to be not needed with CM10.2 and above. But I also know that many CM11 users have reported bricked emmcs after running CM11. I don't know if those were caused by trim or not, but I am suspicious.

You might want to go back to stock OS to see if it is a lag problem. If you do, go to my HD/HD+ CWM thread linked in my signature and make a new bootable CWM SD per item 1a and use it to flash a plain stock zip followed by a factory reset with CWM. That is better than restoring a stock backup since it also restores stock recovery.
[Nook HD, HD+ General] mooooor:
Many thanks for the advice. I'll give that a try this evening.
[Nook HD, HD+ General] adIesumPerMariam:
Many thanks leapinlar. Happily running CM11 on my Nook HD+!
[Nook HD, HD+ General] ranger7:
If I'm running 10.2 and install 11, I assume I lose all my installed apps because of the step in CWM that wipes something. What happens if I don't do the wipe?
[Nook HD, HD+ General] jpisini:
If you are coming from stock you will most likely just hang at boot if you don't wipe.
[Nook HD, HD+ General] leapinlar:
Coming from CM10.2 you may be alright, but it may hang too. If it does hang or crash, just go back and wipe later. Or if you use Titanium Backup to back up your installed apps before you install CM11, you can wipe and use TB to restore your install apps after installing CM11.
[Nook HD, HD+ General] ranger7:
Thanks. I was unaware of Titanium Backup.
[Nook HD, HD+ General] bob.teatow:
Thanks - CM11 Shapshot M8 + one question

THANK YOU. I'm late to this party, but I wanted to say THANKS.:good::fingers-crossed:

My Nook HD+ was becoming unusably slow with the infamous lag problem.

With CM11 it's a great e-reader again and much more.

Question: If one doesn't care about ever "going back", how risky is the upgrade process?

It seems this tablet is booting CWM right off of the microSDcard, so even if I screwed up the internal memory somehow, wouldn't I be

able to boot CWM from microSD, wipe and (re)install? :confused:

I have similar question for some other tablets I've acquired that seem to be microSD bootable.
[Nook HD, HD+ General] digixmax:
As long as the Nook can boot off SD you can use SD-based recovery to re-install CM (or even stock ROM) -- as long as you have not messed up the partition table or wiped the wrong partitions (e.g., /rom, /factory, ...).
[Nook HD, HD+ General] bob.teatow:
How bad could one mess up?

Interesting, I haven't looked into /rom /factory and the partitioning of the internal memory --- I'm not about to mess, but curious - I guess you're saying that these are mutable under software control -- which leads to the question - if you wipe all partitions - would you be "bricked" - or is the processor somehow hard wired or has a protected or read-only region of memory that will try to boot off of the external SD?
[Nook HD, HD+ General] leapinlar:
The boot mechanism is "hard wired" into the processor chip code. That means that it will always attempt to boot to SD if the SD is set up properly for booting. But that does not guarantee that it will boot successfully. The SD boot usually relies on certain partitions on emmc to be valid and to contain certain information. So even though it attempts to boot, it may not complete without a working emmc. So bottom line, be careful what you wipe from the emmc partitions.
[Nook HD, HD+ General] digixmax:
/rom has a set of files containing factory installed device info (ProductID, manufactured data, etc.) and individual device data (serial no., MAC address, security encryption keys, etc.). The device will not run without the individual device data in /rom.

/factory stores a backup copy of the stock ROM as well as a backup copy of the device data in /rom partition (romdata.zip). These backup copies are used by the stock Recovery to restore the device to "factory-fresh" state.
[Nook HD, HD+ General] toeknee0506:
I just wanted to say thank you for the awesome guide for getting CM11 up and running. Great write up. I followed it and had CM11 running within minutes. Thank you!

Thanks- able to get m9 4.4.4 working on Nook +

Just wanted to say an overall thank you!!!. I was able to get M9 4.4.4 working on Nook HD+. Seems smoother & more responsive than 4.4.2.

The only minor things I've noticed are that the wifi does not automatically switch to a stronger signal when available. I have also read some prior posts about location services not always working & this is true for me also. Does anyone know if this latest rom update is suppose to fix these minor problems? Thank again,

Al
[Nook HD, HD+ General] Risible:
Ok, can anyone point me to a guide on how to remove Cyanogenmod? I used the For Dummies guide and it was super helpful (thanks!) but I'm having battery issues and crashing issues and I want to go back to stock and see if it clears up. I made a backup as per the guide, but have no idea what to do with it and I don;t want to brick the device. Any help would be really appreciated, thanks!
[Nook HD, HD+ General] digixmax:
Just reboot to recovery, then from recovery's menu select backup/restore -> restore.

If you plan to stick with stock ROM going forward then you should also flash stock recovery -- see 2nd paragraph of item #5 of http://xdaforums.com/showthread.php?t=2062613.
[Nook HD, HD+ General] Risible:
Awesome, thanks so much for the fast reply!

---------- Post added at 08:43 PM ---------- Previous post was at 07:47 PM ----------

Ok, I assume I screwed up somewhere. I put my backup SD in, booted to clockwork, chose backup and restore, then restore from external_SD, chose the image, and let it run. It then asked me two questions that made me panic and I think I answered no to both. Now if I try to reboot it is stuck in a reboot loop. I have no idea what to do now.
[Nook HD, HD+ General] leapinlar:
Go to that same thread and flash a plain stock rom from item 6, followed by a factory reset with the CWM.
[Nook HD, HD+ General] Risible:
Thanks again :)
[Nook HD, HD+ General] neutronjeff:
Awesome sauce Leapinlar! I had no problems other than READING THE INSTRUCTIONS and FORMATTING AND SETTING SD CARD TO ACTIVE.

Now I have CM11_M9 rolling on my HD+. :)

I'm not sure if this is OT, but can the Nook app be run on CM11? I see that it won't install from Play.
[Nook HD, HD+ General] jpisini:
Yes you can run the nook app but it needs to be side loaded.

Help needed

Hi, guys.

I had been running 10.1.3 on my HD+ for eight months with no issues. Then it suddenly got stuck in a boot loop (for no reason). I've tried everything i can think of: factory reset, wipe cache/dc; reflashed 10.1.3, flashed CM 11 and CM 10.2.1; restored stock back-up; formatted /system and /data. I'm now back on 10.1.3 again; but, whilst, the device mostly boots ok, it will randomly switch off and sometimes even go back into boot loop. Whilst i've had problems with my android phones, I've always been able to fix by reflashing rom. Now i'm completely stuck, so any advice really appreciated!
[Nook HD, HD+ General] leapinlar:
Some of the newer Nook HD+ are quite finicky about booting from SD (I'm assuming you have an HD+, you don't say). Read through this thread for some ideas how to get it working:

http://xdaforums.com/showthread.php?t=2288688
[Nook HD, HD+ General] leapinlar:
The only thing I don't see on the list of things you tried was to flash a plain stock ROM. Go to my HD/HD+ CWM thread linked in my signature and download the plain stock zip from item 6. Flash that with an older CWM and then factory reset. You might also try going to mounts and storage and format 'data and datamedia'. That is a true /data format while the other /data options are just an erase operation, leaving the /media folder intact.
[Nook HD, HD+ General] aciduzzo:
Formatted data and data/media, and then flashed your stock 2.2.0. OS booted fine, but randomly rebooted itself twice during setup. So i tried another factory reset and it seems to be ok so far. At least, i made it thru setup! If it stabilises, i'll try CM11. Otherwise, i'll just have to send it back (with stock) for a warranty repair.

I spoke too soon...it crashed again! So off for repair it goes...
[Nook HD, HD+ General] NTAB:
So I can't get CWM to install, so I want to start from scratch. How can I remove CM11 and get it back to stock nook OS?

EDIT: After rebooting to factory recovery a few times by holding power+n, it finally seems to be doing a nook restore. I'm not sure why its finally doing it after several tries...I'll update again if it didnt work.
[Nook HD, HD+ General] leapinlar:
It is reseting itself because the 8 failed boot mechanism kicked in.

Were you following the instructions in post 7 for installing CM11? Be sure to use the files from that post if installing CM11.
[Nook HD, HD+ General] NTAB:
The main reason for me wanting to start over was that when in a reddit app, and watching videos through youtube via hyperlink, both apps would crash. I only frequent the Titanfall subreddit and it may have to do with the specific reddit app that I use, but I don't know. Just wanted a clean slate and it appears that its not even that. it remembers all the nook accounts that were there before and even kept the play store on the primary account. It also reset itself to 2.0.1 or something like that. :eek:

Gapps for CM11 M9

I have been working on upgrading from 10.2 on my Nook HD to the CM11 M9 version. Only I cannot find the correct gapps file. It would be the file that couples with the zip: cm-11-20140804-SNAPSHOT-M9-hummingbird.zip. I found a tutorial on Andrioidpulp and have been following it. Their recommendation is to use GApps_Standard_4.4.4_signed.zip for the Nook HD but I can't find the file to download it. Then I was going to just use the CM11 tutorial on here to do as I did when I did 10.2 but using the correct files.

I'm doing it this way because when I tried to upgrade it from my updates in my device it did weird things so I just put 10.2 back on and am assuming I did something funky, so I wan to do it from scratch, and hope the upgrades work from then on. (I apologize that the use of the terms "weird things" and "funky" are the extent of my current knowledge besides what I've learned on here. I feel like a housewife trying to describe a sound in my car to a mechanic... only I know far more about fixing cars than computers).
[Nook HD, HD+ General] leapinlar:
All the files you need are in post 7 of this thread. And you are right, you must start clean with CM11.
[Nook HD, HD+ General] little callow kid:
Awesome! Thanks so so much! Sometimes I just need reassurance that I am using the right files before I brick something.
[Nook HD, HD+ General] TPA5:
Hey guys!

First off I want to say a big thank you to all the people who have helped develop, test, fix, and create how-to's for

installing CM! You guys are really awesome, and I am so thankful for all the helpful posts I have read before I registered an account.

I just have a couple quick questions. I am running CM11 on my Nook HD+ and it's working completely fine! It's super slick and I am so happy. However I am curious to know if anyone has experienced poor battery life, and a jittery screen? When I leave the tablet on standby it's no big deal, battery drain is within normal parameters. However I seem to drop very quickly even when doing basic tasks such as web browsing. Sometimes I

Will see drops in excess of 10 percent in about half an hour. Is this normal? If it is that's totally fine, it just seemed a little much to me. If I am gaming with my Bluetooth controller, it really plunges, sometimes up to 15-20 percent in under an hour. Is this also normal? Again, if it's normal that's totally fine, I just want to make sure I'm not screwing up somewhere.

Secondly, does anyone else find they have a jittery, inaccurate touch screen? I find when web browsing if I try to scroll down a page it jumps left and right and up and down instead of smoothly scrolling. Also, sometimes when I try to click a link it clicks slightly above or below it instead. It's just a weird touch screen experience. Is this normal or am I missing some kind of calibration or setting?

Thanks again so much for creating CM, and for listening to my (probably dumb) questions!
[Nook HD, HD+ General] leapinlar:
You are best to ask these performance questions on the CM11 thread. This thread pretty much deals with installation issues. I don't run CM11 so don't know how to answer.
[Nook HD, HD+ General] neutronjeff:
I have to agree that the battery drain in use seems pretty high. However, I think the standby time is improved. Ymmv. I haven't had significant touch screen issues.

Stuck with incomplete install

I installed "cm-10.2.1-ovation.zip" on a Nook HD +. For some reason "gapps-jb-20130813-signed.zip", though installed from recovery, isn't showing up in the Apps (no Play store, for one). If I open the included file mgr, and tap the zip file, I get the error that there's no application associated with that type. I have turned on "Untrusted Sources".

How do I get the Play Store and supporting stuff? How do I get some context-options when I tap a zip file (Install, Extract, etc.)?
[Nook HD, HD+ General] leapinlar:
When you flashed the gapps zip, did it install completely or was there an error message? I suggest you redownload and reinstall with recovery.

And you will need a third party file manager to look at zips (like root browser, ES File Manager, etc.). And when you do, there will not be an install option (just view or extract). Only apk files can be installed.
[Nook HD, HD+ General] bk_xda80:
Thanks so much for the info! I downloaded (in Android's Browser), and reinstalled gapps within recovery. It installed completely (again), but still no evidence of it within Android. I am not a violent person, but I've tried just about everything else. Ok, exaggerating just a little- I just haven't tried the right thing.

I appreciate your help!
[Nook HD, HD+ General] leapinlar:
Go to settings, apps and select all apps and look for evidence that gapps is there. Things like Google Services Framework and Google Play Store.
