I flashed (dirty) the latest experimental version (161030) and got the unending boot animation. Then, I tried again, doing a factory reset, no change. Wiped everything, no change. The installation of the AOSP and GAPPS ZIP files goes fine, I'm not installing any other ZIPs. When I rebooted, I got the gray loading animation, and it never goes beyond that.

For a few tries,, I couldn't even flash the AOSP ZIP - I just get:

E1001: Failed to update system image.

Updated process ended with ERROR: 7

Error installing zip file [...]

Updating partition details...

...done

After wiping everything, I was able to flash the AOSP image again, but now it looks like the newest build wants GAPPS 6 instead of 7.1?
[Nook HD, HD+ Android Development] mikeataol:
if it were me, I think Id eliminate file system corruption first. (at least one of these builds led to f2fs file system corruption and necessitated a reformatting)

and I have had better luck with rebooting TWRP after file system operations.

-----

boot to TWRP, and do the format data (not just the wipe) , in addition to wiping all other file systems

That resets it back to ext4 .

power off, REBOOT to TWRP again

change the data to f2fs, and cache if it isn't already f2fs

power off, REBOOT TO TWRP

load the rom only and see what happens.

If the rom boots. power off, REBOOT TO TRWP , wipe data, then install the correct gapps.
[Nook HD, HD+ Android Development] spragers:
Thanks for the suggestions. I formatted data and changed the cache to f2fs (data was already in that format) in addition to wiping everything else. Installed the ROM only and rebooted. It's been sitting on the gray "android" animation for about fifteen minutes so far. How long should the first boot take? Also wondering if you have any other suggestions as, at this point, it looks like my Nook is toast :-/

I tried installing the latest stable version but get an error that I can't install an older version over a newer version...?

One other bit of weirdness - if I flash the ROM, then immediately try to flash GAPPS 7.1, I'm told it's the wrong version and I need 6.0 (which it lets me install - although I still get stuck on the boot animation). However, if I install the ROM and then reboot, and try GAPPS 6.0, it then tells me I need 7.1.

Ended up trying the CM 13 build once more and it finally booted. Maybe it's just an issue with the experimental AOSP build.
[Nook HD, HD+ Android Development] Shadowpain:
I have exactly the same problems...
[Nook HD, HD+ Android Development] mikeataol:
you can fix the install error (cant install over a newer version) by using 7zip and editing/removing the first line of the updater script in the rom.

more drastic measures that another person says worked was flash the stock recovery, use it to go back to stock, then start over.

Tried the 10/30 Ovation release from experimental on my HD+. TWRP 3.0.2, I get to "patching system unconditionally", and 28 hours later, nothing has changed...

Flashed back the previous release from 10/13, and everything works fine.

Just an FYI, the only thing I run on it is an alarm clock and use it to control plex, so not a big deal.

I was downloading the cm ovation build when it was deleted from the folder.Are you talking about the aosp build?I was thinking about giving it a try.I am on an older cm build that I have downloaded last month.
[Nook HD, HD+ Android Development] Tight Git:
Same here.
[Nook HD, HD+ Android Development] mmnspeed:
New version of CM works fine.I just now flashed it.Remember to download gapps for 7.1(I am using pico) and also flash them before first boot.Gave me a hard time because I didn't do that .

For anyone who is curious,youtube is working perfectly.Some minor graphical glitches in the default browser.Everything else seems good so far.

Edit:There seems to be some issue with wifi.Can't seem to turn it on after turning the device off and then on again.

Wiping cache sorted this issue.I am not even sure if it is an issue in the first place.I tried turning the device off and on again,the problem seemed to have recurred.I left the device in that condition for sometime,but it now seems to have connected to wifi on its own.
[Nook HD, HD+ Android Development] Zippy Dufus:
Finally, a good Nougat CM14 build!

Just confirming that after a couple of weeks of struggling, I got a good build!

Thanks again [MENTION=4473900]amaces[/MENTION]!!

A nougat build appears to be a horrible resource pig with Java 1.8 and the Jack&Jill build tool. I had to give my virtual machine 12GB RAM and 4 CPUs to make this build run end-to-end starting from an empty .ccache directory and a clean build directory (my host machine is an AMD quad core with 16GB). "Google recommends compiling Android on a machine with at least 16 GB of RAM." Sheesh!!

Anyhow, I was able to install Titanium Pro (I saw issues in XDA with Nougat) and restored all my app and data. All is working and life is good! :)
[Nook HD, HD+ Android Development] mmnspeed:
I see the new recovery in the experimental folder but have stuck with the old one.Could someone please tell me if there are any new features or improvements in it?The one I have presently seems to be working fine.

I had a strange issue with my nook on the earlier builds.Perhaps due to faulty restoration with titanium backup.I downloaded roms using ADM and they would download fine,but with zip errors developing in them.Last month I soft bricked the nook several times, getting stuck on patching system partition.I would keep the verify zip option unchecked,thinking nothing can go wrong with a download accelerator like adm.So am a bit wary about touching something that isn't broken.Sorry for the long back story.XDA should award me for the longest,unhelpful posts.lol.:)
[Nook HD, HD+ Android Development] Rab_Kun:
First, let me say thank you [MENTION=4473900]amaces[/MENTION]! I used your CM12 build too. They've always been surprisingly stable, and to get Nougat on an older tablet like this and have it be as usable as it is, is amazing.

The wifi just seems to take a long time to "enable", after about a minute it will allow you to enable it and find the network on its own. I've also noticed the settings icon only gets half rendered sometimes (half a cog), in the app drawer. My homeassistant (home automation) control panel instance in the chrome browser and the kiosk browser was a little laggy, but I assume that's due to the older processor.

Otherwise, it's a great build, it seems a lot faster to boot (about 34 seconds from the cyanoboot screen) and I love the pop out side menu in settings. Video in the browser and tivo apps was smooth, crisp and vibrant.

I can't say what all of the differences between the 3.0.2 and 3.0.1 versions are, but I did have to upgrade to 3.0.2 to flash the latest nougat experimental. (Errored out with 3.0.1.)
[Nook HD, HD+ Android Development] mmnspeed:
Yeah,I realized that myself.The wifi takes quite a bit of time to start working.AOSP builds have far less bugs,but my sdcard with all the data isn't formatted for that.You might want to give that a try.These are early CM builds and will take time before most of the bugs are removed.

I was already on the old 3.0.2 recovery,but have myself realized since yesterday some issues while flashing the new builds with it.Will install the new one.
[Nook HD, HD+ Android Development] corhsin:
Hello all. First, thanks to the authors of these great projects. Keep up the good work.

I have a Nook HD+ 32GB and am hoping to get something that is newly stable and useful. Browsing on the current system is unusable and everything is dated. These are things everyone already knows.

This thread may well have the answers, at 136 pages it has passed the point gathering information is realistic and a study of the first, and last, 5-10 pages didn't result in anything useful. Maybe I can offer up some instructions for the OP when the time comes. Just an idea.

The strategy is to start with the latest and work backwards or wait for patches if something is not functioning. To do so, I have started here: https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3480156918 .

I was working with the instructions referenced in the first post of this thread. The PDF has different instructions, as best can be assumed, as there is no ZIP and instead an IMG file for TWRP. The SD card has been written to an card and inserted in the Nook with the device powered off, here (or maybe one step back) is as far as is clear. Can anyone provide some direction? Trying versions newer than 12.1 and 2.8.7.4 is desirable per the OP, to do so some instruction is needed that is not readily available. Any assistance is appreciated.. Thanks in advance.

I flashed the ovation CM using TWRP 3.02 and it worked fine but after I rebooted it is always going now to the TWRP cover page and freezing!!! Any help would be appreciated
[Nook HD, HD+ Android Development] vinceweis:
Just ran into the same issue. A reboot seemed to have reset everything to a very basic boot and now I can't get to recovery, same as you.

Guess it's time to insert the SD recover card and start over.
[Nook HD, HD+ Android Development] eeter:
I tried to reflash via adb and fastboot ..... no success
[Nook HD, HD+ Android Development] eeter:
Let me know if the SD recover method works for you..........Thanks
[Nook HD, HD+ Android Development] vinceweis:
It did work, however I had to use the old legacy cwm to get it to work. Since then, I reloaded everything.
[Nook HD, HD+ Android Development] corhsin:
Apologies for bumping, I suspect many people know the answers I am seeking. It may be that the question is poorly phrased. Maybe this will help.

I would like to move a Vanilla Nook HD+ to the latest 'experimental' branch without dirty installs. Is that an option? The instructions for 12.1 reference using TWRP to boot by writing the files to a drive in an order, the exp. TWRP 3.0.2.0 is uploaded in IMG format and it does not appear to boot. Can anyone throw a bone for how to start without having to dirty upgrade? Thanks in advance.
[Nook HD, HD+ Android Development] Tight Git:
Which cwm did you use?

Thanks
[Nook HD, HD+ Android Development] mmnspeed:
I don't get from the post what the problem is..perhaps someone who does might be able to help..till then have a look at this thread..http://xdaforums.com/showthread.php?t=2317500...there is a link for cm11 there also...if you have no recovery installed,you would have to make a bootable SD card(it will boot into cwm recovery)......if you are able to do that,you can easily install any ROM you want or any other recovery....the latest roms will require twrp recovery(not cwm)however..I don't remember the exact details of the process as I have done it a long long time back...you might want to go through the guides properly..

If this indeed is the problem,then you can pm me once you have a recovery installed..otherwise hopefully someone else can help you..

Something about the latest build...I installed it and it is the first perfectly working CM build...the wifi issue has been resolved...you might face issues in the stock explorer while using the SD Card,it might not allow you to open some types of files...I used es file explorer to for that....play store wasn't downloading anything...so I cleared the cache and data for Google play services and Google play store and it is working fine now...
[Nook HD, HD+ Android Development] vinceweis:
The one on the SD Recovery. I don't remember the version but when it boots to the SD, there are two TWRP versions and one cwm.

The Nov 9 experimental ovation build is working great for me. Had a couple glitches with trebuchet and switched to Nova launcher. Everything running smoothly and so far, wifi connects great every time.
[Nook HD, HD+ Android Development] belfastraven:
If you are starting from stock, I suggest you use make a bootable sdcard (it's possible you will have trouble with anything bigger than 16g in stock, so try to use a 16g or smaller card). Before you do anything, do a complete backup of the nook--just in case.

On the card put the 3.02 image and ovation rom zip from the erxperimental folder.

You can let the nook boot up into the default twrp from the card. Then flash the 3.02 ovation image from experimental. Twrp will flash the image for you--you can see that possibility after you select install If will ask you where you want it flashed, boot or recovery partition. You of course will select recovery.

Once you have flashed the recovery , Power the nook off, remove the sdcard and boot back into recovery. You should format data and cache f2fs. Then insert the sdcard and install the rom. You may have to wipe the system partition before you do that--you will know if you get an error when you try to flash the zip.

Sometimes people have a bit of difficulty booting from an SD card. Sandisk class 4 cards seem to work well; I have also gotten Sandisk class 10's to work. You make have to try booting a few times.

I hope this helps.
[Nook HD, HD+ Android Development] mmnspeed:
I might have ended up confusing the guy a bit.I haven't used a bootable SD card ever since I installed cwm through it the first time.When I came to the builds cm12.1 builds,I didn't start from scratch.Just changed recoveries.I only now realized that there is a bootable external recovery posted by the OP.
[Nook HD, HD+ Android Development] corhsin:
I am relatively certain I have a handle on this. Boot problems was my suspicion, I remembered someone saying it took them four tries, I tried five different shutdown/starts before I gave it up. I have a 32GB SanDisk UHS-I, maybe I will order a 16GB Class 4. If anyone has better ideas suggestions are appreciated, keep them coming.
[Nook HD, HD+ Android Development] mmnspeed:
You might want to try the older bootable external recoveries.Who knows...you might get lucky.You can then install any other recovery from the older one.If you have the time and nothing is working,you might try that till a class 4 card arrives.
[Nook HD, HD+ Android Development] gascomm:
I'm running cm12.1 on my HD+ & it's pretty much stable. I'm curious how far this (cm13.4 is it?) rom is progressing... how stable & functional is it? is there a list of known bugs yet anywhere? I'm sorely tempted to flash in the hope it handles the notorious lag issue with cm12.1 although I guess that's hardware and unsolvable.

whatever the state of play - keep up the good work. always refreshing to see quality devices being dragged into better OS's.
[Nook HD, HD+ Android Development] mmnspeed:
It is pretty stable.Better in various aspects than cm12.1.Haven't been able to find any major bugs worth mentioning.Have been using it only for around a day though.

Been running aosp_ovation-ota-MOB30Z.160820 for a week now with no major issues. Couple observations and apologies if there were covered in the 137 pages. Wifi doesn't start automatically on my Nook HD+... just have to go in manually and select the connection and then it starts. Is that a known issue? For shutdown is there a way to get Reboot and Recovery mode as additional options?
[Nook HD, HD+ Android Development] mmnspeed:
Yes,it is a known issue.You will have to enable reboot to recovery in developer options.

my bad..that is for CM not aosp...you will have to root and try an app like reboot manager from play store..
[Nook HD, HD+ Android Development] gascomm:
indeed, it's the daunting 130+ pages which have caused me to be so lazy and ask for a quick thread progress summary.

sounds like taking a dip into cm13, now .... where is the latest rom for dL? I will be reading backwards through the thread this evening - just looking to avoid a rough beta if there's a better version hidden in the mountain of text. useful for others dipping in as well I hope.

cheers all, appreciated!

I've been running cm_ovation-ota-NDE63X.161109 and WiFi does seem to behave well. It looks like the audio input bug is back though. Sound Recorder crashes and microphone doesn't work.

Has anyone else given it a try?
[Nook HD, HD+ Android Development] jaydeedid:
I ran cm_ovation-ota-NDE63X.161109 through the paces for a full day and loved it. I didn't experience any issues until I tried the HDMI adapter. My tablet gives me a "smart" tv and without that option, I had to revert back to official CM KitKat builds. Feels like failing because the latest Nougat build worked great otherwise.
[Nook HD, HD+ Android Development] vinceweis:
Sound recorder crashes for me also. The mic does work however. I use Cortana and it works great.
[Nook HD, HD+ Android Development] TBueno:
You're right, I tested it on Evernote and the microphone is functional. There are many alternatives to Sound Recorder too, so my main issue now is Duolingo. Maybe they need to update their app to work properly on Nougat.
[Nook HD, HD+ Android Development] captainw1990:
The cm_ovation-ota-MOB30z.160819.zip ROM no longer works with Gapps pico. The system partition is too small.
[Nook HD, HD+ Android Development] ajislav:
Delete a system apk(s) from the ROM before flashing..

Edit: an app you will not be using, such as - in my case - Gello
[Nook HD, HD+ Android Development] captainw1990:
There are no apks in the system folder of the ROM and I don't know of any other way to delete them.
[Nook HD, HD+ Android Development] ajislav:
You are absolutely correct. Thinking how I ended up doing this...

If my memory is right, I flashed the ROM, then still in recovery, mounted system and deleted the APK and then finally installed gapps..

Or you could achieve the same with a gapps-config file..

About A/V stutters on the latest AOSP builds, do the new test kernels in experimental work better?
[Nook HD, HD+ Android Development] belfastraven:
I'm installing now but won't be able to test till tonight...

On hummingbird with new kernel--Video still stuttering from within chrome_dev, browser, accuweather, nytimes. Video in stand-alone apps like TWC, youtube, is fine. Could this be some kind of webview issue?
[Nook HD, HD+ Android Development] Zippy Dufus:
Success! Thanks for your help!

It is working pretty well too. This is a straight build without any hacking other than the kludge to handle linking in the blobs.

Next up, build Linario gcc-5.2 and rebuild the ROM with it ... just for fun.

Edit: I've noticed the stuttering mentioned in the previous post with playing a large HD MP4 file.
[Nook HD, HD+ Android Development] andtron:
What are thd differences between the aosp and cm builds?

Are they mutually exclusive, meaning you could only install one of them?

Are the flushing procedures the same?

Video stuttering

All video seems to be stuttering whether embedded in a web page, part of an app - Weather Channel. Both with included browser and Chrome. Stand alone video works well with both VLC and MX Player.
[Nook HD, HD+ Android Development] vinceweis:
After new kernel, I initially had the same stutter on a video in dolphin browser. After stopping the video and restarting, it started working fine. Also tried YouTube and no problems with stutter.
[Nook HD, HD+ Android Development] RhinoNelson:
Ovation here and no difference with the latest kernel. I only flashed it and wiped Dalvik. Using 12/08 AOSP
[Nook HD, HD+ Android Development] amaces:
I've recompiled & updated the kernel installers; this time, they're actually tested ;) Go ahead and re-download if on latest AOSP builds.

Nope, just an overzealous cherry-pick; head is spinning after experimenting again with the DMA-buffered stuff.

Great, but you still need to figure out why pvrsrvinit doesn't link properly against the SGX libraries. About stuttering, the stable kernel branches are up to date, so you can sync & rebuild just the kernel, or flash one of the updated ZIPs in experimental.

Umm… OP info, plus Google? Otherwise, yes, the installation procedure remains the same.
[Nook HD, HD+ Android Development] belfastraven:

On 1st I confirm what reported by other users, but I also have to say that my Ovation works really faster now.

This kernel seems to have solved near all memory management issues I had before.

Switching between apps is faster and apps in background+launcher remains in memory now.

Quick Heads-Up about CM13

I'll be switching repos to CM12 soon (only have space to checkout two distributions at a time). If you plan to test the new CM13 builds, do let me know if they're horribly broken so I can attempt to fix them.

I have installed the latest CM MM build and the SD no longer showed corrupted likes the previous version.

Unfortunately none of the file managers I used (the default and FX File Manger) will not show the SD folder, the one that shows (File Manager HD) will fail if I copy files to it.

Anyone else has the same problem?

TIA
[Nook HD, HD+ Android Development] belfastraven:
I am using the File Manager that came with cm13: I have root enabled for it. It is working fine for me (Hummingbird build). How did you install? I did a factory reset and also wiped system (probably not necessary), then flashed rom, pico-gapps, supersu--then booted... (I was coming from the 12/08 AOSP rom).

When you got the message about SD card being found, did you choose to use it as a normal SD card, NOT to extend internal storage?

---------- Post added at 12:47 AM ---------- Previous post was at 12:13 AM ----------

Everything is running very smoothly on the cm13 12/13 rom for me (Hummingbird) I did have to downsize my gapps from micro to pico (didn't try nano)

Have you seen this--it seems that 6.01 is even a bit worse than 6 for space.

http://xdaforums.com/showpost.php?p=64208563&postcount=3393

I notice that ,in developer options, our root option is back. Does that mean that we no longer require superSU to be installed separately? I know that chainfire has a new version of superSU which does not modify system, but it seems to require modifications to boot. I also wondering if you think it would be worthwhile to remove some systems apps, (e.g. browser, email, others to be determined) with the gapps-config file when installing gapps.

One last question: when installing a new rom over previous one of the same type , e.g AOSP over AOSP, what is the preferred install method now?

Thanks so much. I hope that juggling multiple roms and playing with kernels still leaves you time to eat, sleep, play and even work :)
