Great ROM, I love it and many thanks to verygreen for bringing CM10.1 to the Nook HD

One problem to report: Netflix doesn't work well with this ROM. Get really bad audio sync issues (audio lags behind video). I have had to revert to stock where it works as expected. Not sure if this is specific to the ROM, or CM10.1 in general, or whether it could be fixed with a few tweeks to build.prop - I tried a couple and managed to make it worse but maybe I didn't get lucky.

Actually another problem: HDMI out works but the screen stays on and no way to turn if off without turning the external display off too. This is not the same behaviour as stock which automatically dims the tablet screen when HDMI is active. I also think it doesn't scale the output quite correctly (stock seems to go into "full screen mode" when video is playing and HDMI is connected).
[Nook HD, HD+ Android Development] DigitalHeretic:
So am I to understand that this ROM doesn't do the "automatic reset" back to B&N stock if we use an app that changes /system? I've been running CM10.1 from my SD card for that reason and would love to just have it on emmc.
[Nook HD, HD+ Android Development] leapinlar:
It will not reset. Change /system all you want.

[Nook HD, HD+ Android Development] BlueC78:
Thanks for the feedback, does anyone else experience problems with netflix and this ROM? Are there different variants of the nook hd hardware?

I have to admit the last version I tried was 13/06/15 and not tried more recent ROM yet but didn't see anything in changelog to suggest it might have improved. I'll try again once I have a new SD card that I can backup my working stock ROM to.

Also, could be a regional netflix issue - I am using netflix UK service.
[Nook HD, HD+ Android Development] verygreen:
some TWRP goodies for Nook HD too.

flashable zip to have twrp as recovery twrp-recovery-hummingbird-1.zip

I am not promoting this to OP yet looking for feedback on touchscreen performance, which seems to be both too sensitive and too insensitive at times, scrolling big lists is kind of hard (you've been warned).

Post your experiences here.

Also to play with it, adb shell in and

echo 0x80 >/sys/bus/i2c/drivers/ft5x06/3-0038/wmreg
echo 0x16 >/sys/bus/i2c/drivers/ft5x06/3-0038/wmval

Try to play with the 16 in the second string (11 is the default, I have somewhat good results with 9, I think better than with 16, but you let me know what's working better for you).

Roll back roms?

Curious to know: is it possible to roll back to a previous version of this ROM? Can I just install an older ROM, or do I have to toil through some special process to get it working?
[Nook HD, HD+ Android Development] verygreen:
just flash the older version and you are good to go.
[Nook HD, HD+ Android Development] verygreen:
I don't think it's all that easy, I already looked into it.

bb2d core is clocked off the fixed clock dpll_per with a pretty rigid set of dividers, so there's not much we can do there.

There is a possibility to switch dpll_per to another fixed clock, dpll_core that's about 4% faster, but that's about it (and so far the kernel seem to favor in-hardware setup, even though the code says otherwise).

Very similar picture with sgx core too.

I imagine I need to take another close look at trm to see if there are useful dividers we might use.

One area I had high hope for is the l3 hub, all the data travels through there, at the default divider of 2 it's working at 233MHz which is is about 900megabytes/sec it seems. The register settings seem to allow a divider of 1 which would give us 466MHz, though when I tried it once, it did not finish booting hanging somewhere on the way.
[Nook HD, HD+ Android Development] drakester09:
Hope so, it did work that way on Tuna, but the reference I had for those changes did not have any code for 447x, 446x did not have bb2d... might be worth a shot nevertheless.

I'll get around to setting up a build environment next week. :cowboy:

Oops, ignore this.
[Nook HD, HD+ Android Development] mystichobo:
Hey Verygreen!

I picked up a Nook HD today with the whole firesale thing as I needed a cheap tablet, and had this installed within 15 mins of getting it hope. Awesome job!

I have a quick question, is there any way to tweak the screen's colour values? At the moment, mine has a very slight warm tinge, especially at lower brightness levels.

Also, thanks for providing the device source, might have a shot at building it over the weekend.
[Nook HD, HD+ Android Development] samomamo:
Verygreen why is the minimum CPU frecuency is set at 800? Is that going to eat up the battery faster? Bye the way thanx for the ROM its really smooth.
[Nook HD, HD+ Android Development] hellslave:
Is it alright if I just install over my current build with this one, or should instill do a data wipe and clear the dalvik?
[Nook HD, HD+ Android Development] leapinlar:
Just flash over the top without any wiping or clearing.

[Nook HD, HD+ Android Development] verygreen:
That should not be really happening, I am pretty sure I reverted that patch long ago.
[Nook HD, HD+ Android Development] Windsor1959:
I also encountered this after installing the latest build. Easy enough to change, though!
[Nook HD, HD+ Android Development] verygreen:
Hm, indeed, I certainly see it.

Night of the undead patch, huh?

I'll address this in the next build.

Your changes would be reverted next time the screen is turned on, though (it's still at low freq with the screen off).
[Nook HD, HD+ Android Development] rushless:
How be this?
[Nook HD, HD+ Android Development] Windsor1959:
Normally, you can change the CPU speed settings under Settings - Performance - Processor. But, if I am reading verygreen's reply correctly, the change won't stick until he releases the next build.
[Nook HD, HD+ Android Development] Bruce777:
Thanks Verygreen; amazing work!

I just wanted to report a bug after flashing the 7/6 build. My "recent apps" soft key (at the bottom next to home button) stopped working. If it's user error please let me know.

Thanks again.

EDIT: fixed it. Went into system settings > navigation bar > buttons and layout. I removed the recent button altogether, saved the settings. Did the process again and added the recent button back and it worked.
[Nook HD, HD+ Android Development] bckrupps:
is there any real harm or negatives to setting my build prop to 320 on the nook HD? other than potential market issues it is awesome for flipboard and pulse readers. any better number to use and also any way to move the soft keys back down to the bottom with this change. its the only thing I don't like
[Nook HD, HD+ Android Development] leapinlar:
I use 320 and have for months. No downsides. But don't do build prop. Do local.prop like I instructed a few posts back.

And what do you mean soft keys at the bottom? That's where mine always are. Where are yours?

Edit: oh, this is HD. I did have trouble with 320 on the HD. SystemUI kept crashing. But that was months ago with bokbokan's build. Might be ok with verygreen's now.

Also that instruction was on the HD+ emmc thread.

[Nook HD, HD+ Android Development] bckrupps:
yeah i got the hd. surprisingly i like it a lot for most things. No crashes or issues at all thus far on cm 10.1. i used rom toolbox pro to change it. is that ok for the smaller tablet?

---------- Post added at 06:53 AM ---------- Previous post was at 06:52 AM ----------

the color tweaking was a question of mine also
[Nook HD, HD+ Android Development] leapinlar:
Yes it is okay, but with that you have to tweak it every time you flash a new ROM version. If you use my tip to use local.prop from the HD+ thread, it sticks with a ROM flash.

[Nook HD, HD+ Android Development] bckrupps:
Thanks. I had the HD+ but switched to the HD for the portability. You 3 main devs are taking up alot of my time lol. I'm always looking for new tips, rom upgrades and such on here. Makes me wonder if you actually take time to use the tablet ha ha

Battery drain

I just installed the 7/8 build. Let it sit overnight to test battery drain. I'm getting about 1% per hour drain. Is this normal? I didn't tweak anything yet. I remember in my old nook days that deep sleep was always an issue. Are there any settings to help mitigate the battery drain in standby/sleep?

Also I got rid of the stock clock widget and tried to put it back. Using cLock widget and weather never shows up even though there are settings for it.

Thanks.
[Nook HD, HD+ Android Development] Sherip:
Concerning returning to plain stock --

I've had occasion to want to restore original stock on both an HD and an HD Plus. I don't think the posted original 2.1 stock files work unless you already have stock on emmc. So before installing any alternate system on emmc, I think its very important to make and an own stock backup. On an HD Plus, I had CM 10.1 on emmc. In CMW, I cleared the caches, selected factory reset, and then tried to install the available original stock 2.1 zip. CMW went so far as to delete boot and some other areas before reporting some library file was missing, and quit. At that point all the Nook would do is boot loop, and it continued to do so after 8 restarts. I then restored my own stock backup. Once that was on board the original stock zip installed properly. So I was glad I kept my stock backup.

One other note about restoring my stock backup. I booted the Nook after the restore. My avatar file was possibly not available. It booted showing a photo image of a very angry looking man (as the avatar) I'd never seen before on the lock screen!

Question -- Is it possible in CMW to delete everything from internal /sdcard? That's important for a Nook you are disowning. I've deleted folders from the My Files area of the stock Library screen but some invisible files or folders might have remained. I learned the hard way that "format /sdcard" on the CMW menu means the micro SD card (at least if CMW booted from micro sd).

[Nook HD, HD+ Android Development] leapinlar:
You should be able to use my plain stock 2.1.0 zip from my thread over the CM10.1 ROM. Get it by going to my HD/HD+ CWM thread linked in my signature.

I have had that angry guy (John) too. Don't know why.

Yes, you can use CWM to format /data and /datamedia (the last option in the mounts and storage menu). It will clear all your data including the internal sdcard.

[Nook HD, HD+ Android Development] Sherip:
Those were the downloads I used. Is the problem that I first used the CMW factory reset option?

Thanks for the info on eliminating user files and data. Any harm to do it after the fact?

Sent from my Nook HD+ Running CM 10.1 from emmc
[Nook HD, HD+ Android Development] leapinlar:
Huh. Those should have worked. Well, best to use the backup anyway.

No, do the format any time if you want rid of all your data.
[Nook HD, HD+ Android Development] GinoDivx:
I am noticing this too. I think an older release (end of June-like) had a better battery consumption.
[Nook HD, HD+ Android Development] killersloth:
When I restored stock backup on my HD it gave me that picture too. Looked like Walter White from breaking bad lol.

Very strange.
[Nook HD, HD+ Android Development] Windsor1959:
I used to get that picture often when I had stock on my HD, even before 2.1. I just figured that it was B&N's way of saying, "We know you root, and we're pissed!"

Got that angry man avatar restoring my stock backup! Had to clear /data /datamedia and reset up the nook and now it's gone. Going to exchange my HD since the bezel is peeling from the screen on all 4 corners.
[Nook HD, HD+ Android Development] hellslave:
Ever since updating to the july 8 build, my wifi will randomly drop out completely. the icon will be there but without any bars and I won't be able to connect. the settings section will be blank as well. the temp fix for this seems to be to disable and enable wifi from the quick settings dropdown menu. but it doesn't last long. I've had to do this now just in the time it has taken me to type up this reply. this seems to affect other aspects as well. for example, I'm being told "dropdown" is spelled wrong. but tapping it, and then tapping to add it to the dictionary gets no response while my wifi is seemingly not connected. the very moment I turn wifi off via quicksettings however, the system responds to the request to add the word to dictionary and pops up the word entry box.

[Nook HD, HD+ Android Development] verygreen:
Well, works for me, though granted I have much more battery left. Does it do this even plugged in?
[Nook HD, HD+ Android Development] Thistleknot:
haven't tried it yet.

I had a rom in the past that did something similar, it was because the battery was reporting a false amount of charge (although in that case, when it did turn off, it didn't turn on again until I plugged it in, this case it does turn back on).

I'll try to fully charge it, and see if it does the same.

[Nook HD, HD+ Android Development] cybernevets:
verygreen - thank you for this.

I was fortunate to be able to buy one of the $80 NookHD's from OfficeMax and installed CM10.1 to the EMMC this morning. It took a few reboots to get things working (wouldn't authenticate WiFi at first, then wouldn't login to Google Play). Everything works fast and fluid. I'm really enjoying the 1440 x 900 resolution on the 7" screen. I previously had an NookHD+ and found it laggy with running stock 2.1.0. I suspect the challenge with the HD+ is pushing those 1920 x 1280 pixels.

If anyone is thinking about running CM10.1 on their NookHD EMMC - I recommend that you go for it. The performance and feature difference of CM10.1 over stock is significant. As always, back your stuff up first.

Good to know! I'm new to Nook, so I'm not entirely familiar with development on it. Thanks for your hard work on getting CM10.1 on it, as well as the recoveries. I hope that now with it being discontinued by B&N, we get some more official support from AOKP and CM10. Either way, it's a neat little tablet and has some potential.

I'm having some issues with random reboots. Usually it just blacks out and goes into the cm screen and quickly back to the lock screen, but sometimes I get the battery is low notice and then a minute later it reboots. Any idea? The random reboots occurs about once every other day and the battery reboots only a couple of times. I started out with earlier builds and this didn't occur until sometime in late June, I think.
[Nook HD, HD+ Android Development] Yianaki:
Random Reboots too clean install.

I just did a clean install last week of cm-10.1-20130712 and I am getting random reboots every other day. It reboots after five ten minutes of use after leaving the tablet alone for a day or so. Wifi is set to turn itself off after 15 min inactivity.

If anyone could point me to a stable old evergreen ROM for this tablet until reboot is fixed, I would appreciate it. Reboots only happen every other day or third day so am very happy with this ROM. Will try the latest rom and see if that fixes things.

Thanks so much for this wonderful ROM. I had a lot of epubs and stock kept on showing syncing library drove me nuts. Also on stock Bluetooth never turns off once you use a BT device *(even if you actually turn off BT), would drain battery in a day. Am so happy with my purchase. Hope I don't go do something stupid like buy more of these just because they are such a great value. You can't find a nice 1080 9-10 tablet for cheaper.
[Nook HD, HD+ Android Development] verygreen:
Please grab /proc/last_kmsg after such a reboot and post it somewhere
[Nook HD, HD+ Android Development] verygreen:
The "soft reboot" where you briefly get to a rotating logo screen are known to be caused by a filedescriptor leak in google maps. Reportedly latest google maps update fixes it.

With the battery low notice, is the battery really low when it's reported?
[Nook HD, HD+ Android Development] Yianaki:
Sorry Just noticed this forum was for the HD, I have the HD+. Will grab file on next reboot and post in HD+ forum. Thanks Much, again wonderful work.
[Nook HD, HD+ Android Development] brendac87:
About the battery reboot, the battery is never low. It happened twice today, I flashed the 07/19 last night. It usually doesn't occur that often. The two times it happened today, after the reboot the battery show percentage at 90 and 78.
[Nook HD, HD+ Android Development] sqs1shu:
6/30 ROM has a good battery life (lasted >15 days with ~5 hours screen time and 15% left) and no reboot observed, 7/19 one reboots every a few hours, and its battery usage during sleep is reasonable (consuming very little battery) and much better than other July builds.

Thanks, verygreen and devs.
