>I have set up options for the screen lock and have encrypted the tablet

As far as my experience, Android device encryption is rarely used by hobbyists, because it only protects against a small subset of dangers to your device, and does nothing for the most common attack vectors--malware or privacy-exploits taking advantage of user ignorance. The issue isn't unauthorized access of user data; the issue is that the user doesn't know enough to restrict access when apps ask for it. Moreover, user (calling) data is more important on a phone than on a tablet with no access to WAN connectivity.

Enabling encryption will complicate outside-the-OS operations, eg using CWM to backup/restore, again since encryption isn't taken into account by most of these tools. As well, you may encounter issues within CM. For example, encryption will affect overall speed and responsiveness of the device.

There are better ways to safeguard your privacy. The most effective is to restrict use of "free" commercial apps/games, as their monetization method is by mining your personal data for ads (and other purposes). The downside is that that removes about 90% of all the apps in Play Store. As a compromise, the more technical can avail of apps like Droid Wall and Permissions Denied.

More details on privacy best-practices can be found here,

No screen lock when rebooting

Hi e.mote

Thanks for the advice and the quick response (and the whole thread). I'm more concerned that the device is wide open every time it is power cycled though. The only reason I turned the encryption on was in the hope that the extra step would force the screen lock to appear on reboot.

This doesn't happen on other Androids I'm familiar with but this is the first CyanogenMod install I've done. Right now I'm hoping it is something specific to my install. Can you (or anyone else) confirm whether a reboot goes directly to the home screen on the Nook HD with CM10.1?

Thanks.
[Nook HD, HD+ General] e.mote:
>Can you (or anyone else) confirm whether a reboot goes directly to the home screen on the Nook HD with CM10.1?

Yes and no. On my one of my HD+'s, I was able to bypass the lock screen by simply waiting for it to timeout, after which then it goes into the Home screen. On another HD+, the lock screen stays in place as appropriate. I compared both's CM settings, and the error/bug is traced to the Display > Daydream setting.

When Daydream is on (at least with default 'Color' option selected), the lock screen can be bypassed upon a Daydream activation. The workaround is to disable Daydream. This may or may not be your issue. On a normal or power-up reboot, my HD+'s always go to the lock screen first.

Edit: Hmm, please disregard the above. It seems that unless a PIN is assigned, any activity would allow a jump from lock screen to Home screen. I'll have to play with this further.

As to your question, it's likely to be an issue specific to your setup, as that would be an obvious and very noticeable bug, and would have been reported before now.

>I'll re-flash the ROM

Yes, that's the catch-all troubleshooting tip. When all else fails, re-install. If THAT fails, return for exchange.
[Nook HD, HD+ General] danovision:
Thank you for taking the time to check that out and go through those settings, e.mote.

That's the behaviour I'm hoping for on my 7" Nook HD, so I'll double-check my Dream options and if that doesn't do the trick I'll re-flash the ROM (which is also the only way of undoing the encryption).

Will update with the results.

Update

Summary:

Combinations of Dream settings had no effect so I re-flashed the Nook HD and all's good.

Detail:

I recreated the bootable SD, formatted the /emmc from the SD's CWM, then installed CWM, the ROM and gapps to emmc. All worked as hoped; lock screen on reboot worked again. I went through settings to try and replicate issue but could not.

My Nook HD now reboots to lock screen every time.

My (very wild) guess is that the issue I experienced was a 'stuck' preference when reading the Quick Settings panel's Lock Screen toggle at boot. That feature can override other settings, but this time works perfectly on my re-flashed Nook HD (ie when its enabled it's always enabled, when it's disabled it's always disabled, with no changing of behaviour after reboot).

Thanks again to e.mote for helping me determine it was an issue with something in my install and not the ROM itself.

Do you know what causes infinite boot when flashing CM10.1.3 on top of CM10.2? Full wipe is mandatory?
[Nook HD, HD+ General] timmyd463229:
If I use the bootfiles does it still make the sd card unusable after or can I delete the files off the card after and use as storage
[Nook HD, HD+ General] leapinlar:
It does not make it unusable. You can delete the files and reuse the card. But I highly recommend against that. You should be using a relatively small card (4-8Gb) and save the card for future use as a bootable CWM. You WILL need it again.

question re modded and official OS...

whats the difference between modded cm-10.1-20130801-UNOFFICIAL-ovation-emmc.zip VS cm-10.1.3-ovation.zip (from official site)? does installing this OS vs the stock B&N void the warranty?
[Nook HD, HD+ General] evobb10:
I flashed cm10.1 unofficial avation.zip fromOP but doess not work. Unfortunatly my device rooted and has cwm recovery with out sd-card. So now can I flash cm10.1? Or I need to do something.

Thank you
[Nook HD, HD+ General] :
Hi Guys, I am new to the forum and in possession of a brand new Nook HD+, A few questions,

1. I have extracted the image file for cm-10.1.3-ovation.zip or should it be NookHDplus-stock-2.1.1-rooted.zip? and in the step by step guide it says the image should be about 4GB but I only see a 4.8mb image file, What am I doing wrong? and when I extract it, there are also two folders META-INF and SYSTEM, do I do anything with them? Next problem is that when i write the image to the sd card, do i read it in windows explorer? as I can't read anything and it says do you want to format? or can i only read it with win32DiskImager?

2. Once i get as far as doing a backup of the Stock Rom, to put it back to stock again if i wish, do i just boot up into CWM recovery and restore the original Backup?

3, I bought a Groovy case from Nook which puts the Nook into sleep mode when you close the cover and boots up when you open it, Will this function only work with the original stock firmware or while it still have this function with the Cyanogenmod?

4. I also want to mention that the Nook has version is 2.1.1,from the latest update, I notice that that are not in the US might have had problems rooting it, I am in the UK?

When people say problems, do they mean that it could wreck the Nook?

Appreciate some answers,

Thanks.
[Nook HD, HD+ General] leapinlar:
1. You are extracting the wrong file. That is the CM10.1 install zip. Read the instructions again. You get the image zip from my thread.

2. Yes

3. Both

4. Makes no difference which country you are in. Should root nicely.

[Nook HD, HD+ General] gamerka:

Thanks for your help, it seems I stuck on 10.2.
[Nook HD, HD+ General] islander2013:
ah ok... i meant there is an official cyanogenmod from download.cyanogenmod.org/?device=ovation and then there is the version which is in this guide, cm-10.1-2013####-UNOFFICIAL-ovation-emmc.zip.

whats the difference?
[Nook HD, HD+ General] martytoo:
I did something dumb yesterday. I downloaded a hummingbird file that didn't agree with my hybrid installation. Instead of installing on the sd card it installed on the Nook HD. So now I assume I have to get the Nook HD back to stock by hooking it to my PC .

What is the easiest way to get it back to stock. Well I have to call B&N to register it if I am successful?
[Nook HD, HD+ General] leapinlar:
Those builds were made before the CM10.1 became official starting in August. Since it became official they were not updated anymore. CM did the updates after that, ending when the stable version was released. So they are the same only stable is newer with more updates included. So if you want CM10.1 use the stable.

---------- Post added at 02:14 PM ---------- Previous post was at 02:10 PM ----------

No. Go to my HD/HD+ CWM thread linked in my signature and flash my plain stock zip in item 6. Then do a factory reset with CWM and re-boot. Then you can register again just like it was new. No need to call B&N.
[Nook HD, HD+ General] kangi26:
Any time you are flashing a different build (10.1/10.2), it's best to backup and a full wipe. You'd only be asking for trouble
[Nook HD, HD+ General] martytoo:
Thanks. It worked even without the factoy reset which made things easier. You are doing us a great service.
[Nook HD, HD+ General] :
First of all, what a difference Cyanogenmod makes to the Nook! My son has the stock firmware on his and it looks dull and sluggish, but he is nervous about updating it, this is fresh looking and smooth, I have noticed though that Google Earth has locked it up a few times, don't know if others have experienced this, but a reboot sorted it, also when I start the Nook up from sleep mode it takes about a minute or so to connect to the internet,although the wifi signal is there.

The version i have is 10.1.3 stable version.
[Nook HD, HD+ General] D000XXX:
Guys, grab a piece of that awesome 10.2 already, it's been working well for me for over a month now and gives you a completely new feeling of smoothness.

There's no reason to torture yourself with an overly outdated version of Android.

[Nook HD, HD+ General] D000XXX:
There's more and more people migrating. I don't have any problems, some supposedly do and many don't. But if, then it's mostly that you don't see the Access Points so you may have to type the name in manually, but there's no more loss of connection etc. So it's totally usable for your everyday environment.

IMHO the advantages in speed and smoothness outweigh the small disadvantages by far.
[Nook HD, HD+ General] timmyd463229:
I was reading about this trim thing which im not sure what it is other than it helps lag is it integrated into 10.2?
[Nook HD, HD+ General] D000XXX:
It's the same thing that defragmentation was in the pre-SSD era, it keeps your device nice and fast, which before was not the case. It is still disabled by default, so you're not risking a thing when you do the switch :)

But of course it is a lot nicer when turned on, you just have to decide how much risk you want to take (no bricks have surfaced in recent history, nobody knows exactly why it doesn't happen any more, but many people including me assume that we will be fine). If you want to make sure, MAG2GA in Revision 05 is the chip suspected to be faulty, you can extract the value and see if you're device is generally considered safe (not a guarantee, though).
[Nook HD, HD+ General] timmyd463229:
How do I find out what chip I have
[Nook HD, HD+ General] D000XXX:

Hi. thanks for this excellent guide. I've been running CM 10.1 for a while on a HD+ and it's been great. My friend has just got a HD+ and I want to install 10.2 on his to see what it's like. Is there a 10.2 build that people recommend I choose or shall I just try the very latest nightly build and see how I get on? With so many nightly versions I don't know if there are any that are better than others or some that should be avoided for some reason?

Many thanks for any help/advice :)

i seem to be struggling at the first hurdle, all files have been downloaded , the 4gb bootable has been extracted and is ready to be burnt, i have set the sd card to active and i have installed the cwm recovery zip image to sd card and inserted and booted , but still no clockword mod,,,,

thanks in advance
[Nook HD, HD+ General] leapinlar:
You said ready to be burnt. Did you burn it with win32diskimager?
[Nook HD, HD+ General] fr33radicalls:
yes , i think there is a problem with me understanding part of the process i think, i've got one 8gb micro sd , i have managed to boot from it like you said by using win32diskmanager to put the image of the file cwm 6027 on it, but when i get to that point i'm struggling , i'm under the impression that i've got to install cwm recovery before anything , so i can then back up everything on the stock nook and then possibly save that to the sd card and then a safe p[lace on pc, so i can then reuse the micro sd to then installcwm 10.1 if at all possible,

thanks in advance , and i apologize as well for my lack of understanding of the process , doing my s2 seemed like a breeze compared to this, and as this is my daughter christmas present i didnt want to make any costly mistakes,,,

---------- Post added at 04:03 AM ---------- Previous post was at 03:56 AM ----------

my daughters only 6 , but is used to my s2 and my partners 23 os, so that was one of the main reason for root along with obviously the ability to put third party apps and also the possibilities of usb host control which if i understand correctly will allow me to reuse a 32gb pen drive i have so i can keep swapping film back and forth without the need to keep going into the internal or external memory.......

thanks again in advance,,,
[Nook HD, HD+ General] leapinlar:
The first important step is to get the newly burned CWM SD to boot when you insert the SD into the Nook and power on. When it boots successfully you will see the title 'CWM based recovery...'. Then you can use that to back up stock and install the CM zip. Putting CWM on internal memory by flashing the recovery zip is not really important or necessary. Getting it to boot successfully to the CWM SD is where most users have trouble.

problem with wifi in recent cyanogen mod

hello all, after messing with the nook os for a few days, I missed the old cyanogenmod, and went ahead and flashed everything to

cm-10.2-20131219-NIGHTLY-ovation.zip from the cyanogenmod website. After that I installed the gapps, and everything is nice and dandy. However, I am noticing a problem with wifi- the first time I turn the device on, wifi works well. However, if I try to connect via wifi after the first time (for example if I connected at home and am trying to connect to a wifi signal at work), then wifi doesn't work- it just says all networks I have saved is out of range, and cannot find any networks at all.

I was able to replicate this issue multiple times.

Anybody else ran into this issue? Any and all advice will be appreciated. Thanks!

1. What is a good cm10.2 thread I can keep track of?

2. what do you think is the most noticeable difference of 10.1 vs 10.2 for cm? Is it worth upgrading at the moment?

Yes you can, but there will not be enough room to store a backup there. Your best bet is to use my new procedure to make the SD per my instructions in item 1a of my HD/HD+ CWM thread where you got those zips. That procedure will allow you to use the whole 4GB.

[Nook HD, HD+ General] leapinlar:
You do not have to worry about the trim bug running CM10.1.3 unless you install the lag-free app from the Play Store. Trim is not part of CM10.1.3.

[Nook HD, HD+ General] leapinlar:
TRIM is not included in CM10.1.3. The only way to get trim to work on CM10.1.3 is to run that lag-free app from Play Store. And you do not want to do that if you have the buggy emmc chip.

Edit: It is not included in stock either if that is what you meant.
