Carbon is based on Android 4.2.2 not 4.3 it is unofficial because it isn't built by the Carbon team. I have been using B11 for over a week now and I have had no reboots or major issues. It really depends on the device some work better with Carbon and some with CM. Try both and use the one you like the best. B11 is a very nice Rom and works well.
[Nook HD, HD+ Android Development] crashff:
With my 32GB NookHD+, I got tired of the Nook reset built in and wiped it and loaded CarbonRom B11 in place. I couldn't be happier. This thing has outperformed my expectations of a $170 10" tablet on Jellybean.

Something I also tend to do to improve system storage space is run Links2SD use it to shift around system apps to user apps. (it will freeze, move user to sys / sys to user, uninstall system apps.. and it's free) I did strip out the live wallpapers, disabled Halo.. things like that. I find Andoird is like Windows in this regard. The more non-essential stuff you can pull out of it, the more stable and responsive it gets.

After 2 days of use and standby, it sits around 430MB RAM used in running processes, even with all the cached background processes.

My only recommendation to users would be to try out Nemus Launcher with it. I think I might have gone a little overkill when I threw a 32GB microSD in it :D

I did run into an issue about the lock screen wanting to use a (nonexistent) camera.. I found an app that will let you disable that though, and then everything is good.
[Nook HD, HD+ Android Development] 123421342:
Free memory is wasted memory, thats the linux way.
[Nook HD, HD+ Android Development] jpisini:
Which app did you use to fix the issue?
[Nook HD, HD+ Android Development] mpeg3s:
Any installed Web video codec for the OS? Not talking about FLASH!
[Nook HD, HD+ Android Development] merchant2112:
B9 was good. had no issues with it. yes its still 4.2.2

i have not run into any major issues with 11 since i did the clean install.

as for other rom's the only other one i would run is cryogen.
[Nook HD, HD+ Android Development] rob00:
Thank you for all the education, suggestions and insights.

I did a clean rom install, and no change. The same boot/reboot freeze persists.

I uninstalled some /system apps (w titanium backup), and it gave me more ram/space, but no change in the freezing department.

Here is some new info that might be a clue to someone. After I cannot get it to boot/reboot at all, I found that if I delete the cache partition from within CWM, which also reformats it, then it will boot. It will also "optimize" all my apps, taking a long time, but at least I can boot into carbon. Could there be a link w the cache partition and rebooting? I reboot using the standard android reboot (holding down the power button, then selection reboot or power off, not a forced hard reset).

I love carbonrom so much, that I am still hoping to find a solution. Thanks again.
[Nook HD, HD+ Android Development] lancorp:
I took the plunge and upgraded from a long running (and stable) B4 to B11. Wiped caches, etc, before and it's up and running, but I am noticing now that my screen flashes randomly. It NEVER ONCE has done that under B4.

Is there a setting or something I should look at that would be causing this?

Thanks.
[Nook HD, HD+ Android Development] 123421342:
You wiped system too? And factory reset?
[Nook HD, HD+ Android Development] killersloth:
Trying to sync carbons 4.3 trees but internet sucks lol

After work I'll try some more. Still might be incomplete/unstable.

Usually the prebuilt toolchains and the kernel tree are too much to sync on tether, but by referencing the repo I've already synced I can make it work. Not working this time lol need real WiFi.
[Nook HD, HD+ Android Development] lancorp:
Factory reset, as it back to the NOOK OS? No...I was under the impression I could update Carbon version by wiping the caches and system.

Everything else is OK (once I loaded NOVA Launcher to get my desktop back), just the random flashing/blinking of the screen.
[Nook HD, HD+ Android Development] killersloth:
HD? Turning screen on and off fixes it, not sure of the cause. Going to rebase with 4.3 and add the governors and schedulers back in to the kernel. Hopefully fixes that issue.
[Nook HD, HD+ Android Development] lancorp:
9" HD+ if it makes a difference.

Turning screen off and on as in hitting the side power button to sleep and wake? Closing the lid on my case (magnetic) doesn't have any effect...
[Nook HD, HD+ Android Development] killersloth:
Idk, don't have any issue like that on my HD+ and I just got a flip case with the magnet. Hopefully the clean start soon fixes it.

First 4.3 build may not have my kernel additions but I'll be adding to it as I get time, if I can get it to sync.
[Nook HD, HD+ Android Development] killersloth:
Hopefully this builds and runs as it should.

That would be nice :) I'll know when I wake up and share the outcome.
[Nook HD, HD+ Android Development] dbh369:
Having an error now on all Play Store actions- RPC S:5 AEC0 error retrieving information from server. Can't update or install anything. Any ideas?
[Nook HD, HD+ Android Development] Reed-Sternberg:
Removing the Google account and re-adding it should fix the problem
[Nook HD, HD+ Android Development] killersloth:
B12 will be up before I have to work if everything works. Ran into an issue with hummingbird but I think it's fixed. Building both now.
[Nook HD, HD+ Android Development] jpisini:
Thanks for all your work. B11 is working really well for me even the amount of times I have to double open the cover is way down. looking forward to seeing what this looks like on 4.3.
[Nook HD, HD+ Android Development] killersloth:
Overheated halfway through hummingbird build, but on ovation the rotation is weird and portrait navigation bar buttons are terribly large.

Carbon isn't finished with their 4.3 repos AFAIK. But all hardware works fine. Hopefully they'll be finished soon.
[Nook HD, HD+ Android Development] jpisini:
Thanks for the update.

[MENTION=3459071]killersloth[/MENTION]

When working on the kernel have you ever seen anything relating to color calibration? White balance, color temp, individual rgb settings, etc? I've noticed that the HD+ is shifted pretty warm (too much red) with greys being brownish. I don't know if it's something B&N went for or if they just didn't bother to calibrate the screen well. But my Archos G9 has more accurate color than the wonderful IPS LCD in the HD+!
[Nook HD, HD+ Android Development] waflsk8s:
Once B12 is out is there a way to use pinguy1982's tweaks with it? I know it has something to do with init.d but not sure how to get it to work through different updates.
[Nook HD, HD+ Android Development] webdroidmt:
Hi ks, hope all is well. Just got back from vacation a couple of days ago and had to do some catching up.:D

Anyway, don't know if this affects your builds or not but Carbon's new nightly for 8/13 on the N7 is their first 4.3 release and so far, it appears to be running pretty well. So, don't know about their repos but maybe ready now...or soon? :)

Mike T
[Nook HD, HD+ Android Development] killersloth:
I'll sync up and try to start a build before work. Was messing around with Slim to see if rotation issue was present but it errored out. Missed the error message because it started hummingbird build right after lol. Hopefully carbon is ready for a proper build, thanks :)
[Nook HD, HD+ Android Development] webdroidmt:
Nice! As for Slim, tbh, I was never too fond of their rom. Actually, I am a CM fanboy :laugh: and I always prefer roms that are based on CM, like Carbon.

Carbon 4.3 on the N7 has one glitch so far that I've noticed, settings/storage FCs which messes up storage and MTP connection. I'm sure this has to do with the new vold/fstab storage format Google implemented in 4.3, which is now in the kernel's ramdisk as opposed to a vold.fstab in etc folder. Until they fix it, just flashing another kernel image(and there are plenty on the N7) with the proper ramdisk solves the issue. Of course, shouldn't be an issue on the Nook which uses its own kernel.

Other than that, aside from some typical 4.3 app compatibility issues, IMO, their 4.3 runs better than their 4.2.2. Hopefully, this will translate into a nice build for Nookie. :D

Thanks,

Mike T
[Nook HD, HD+ Android Development] killersloth:
My test build of Carbon 4.3 was real nice and smooth without any apparent issues besides the rotation and sizes. I'm short on time these days so I'm hoping things just work as they should lol.
[Nook HD, HD+ Android Development] webdroidmt:
We can only hope. LOL One other thing I just noticed is that there is no tablet ui, don't know if it's something they plan on adding down the road, or it's been abandoned???

I don't use tab ui anymore, got used to phablet, so I didn't notice it right away. Maybe I just couldn't find it. :D

Thanks,

Mike T
[Nook HD, HD+ Android Development] killersloth:
I didn't have ui settings in test build either, probably just not merged yet.

Slim builds didn't error, they just didn't package the ROM lol. Packaged ovation build, going to test it when I get off work. Also started builds for carbon, as long as the laptop didn't overheat they should be ready for me to test tonight as well.

Working 3 hours late again too, wanting to just leave now like I was supposed to, but uhh...$_$ lol
[Nook HD, HD+ Android Development] jpisini:
You should get a chiller mat for the laptop. I picked up a cheapie for $6 over five years ago and it still works.
[Nook HD, HD+ Android Development] killersloth:
Wish it was that easy lol

My internal fan has been out for awhile, this is the only thing that can keep it from overheating at this point :p

Edit

So... Slim is working perfectly, while carbon is still rocking an extremely large set of navigation buttons and a rotation animation issue. I've asked around about the rotation problem, because I'm not so sure what to look for to fix it. Hopefully I get some help with it :)
[Nook HD, HD+ Android Development] stegg:
Soo... Give us Slim! :sly:

[Nook HD, HD+ Android Development] jpisini:
How much is a fan? Is it something you can do yourself?
[Nook HD, HD+ Android Development] killersloth:
Thinking about it :)

Typically I could. This laptop though, I've tried to take it apart, and I always get stuck. Miss one or two screws somewhere in there lol.
[Nook HD, HD+ Android Development] jpisini:
Where do you live? I am in Massachusetts I could help you if you are close.

I wouldn't mind a copy of slim if you feel like uploading it. :)
[Nook HD, HD+ Android Development] killersloth:
Florida :p

I'm heading to a friends house to upload on his WiFi, no work today lol.
[Nook HD, HD+ Android Development] bpaulien:
I understand that. I tried taking apart my wife's laptop to replace the fan a couple months ago. I think the fan is the furthest, most remote part of the computer. After watching a YouTube video and dismantling about 8 layers of computer parts, I finally got to where I could see the fan. But only the back of it. In order to get the screws out, I would have had to remove even more stuff, and I was already mentally exhausted. :eek: so I put it back together and said, "use it until it dies."

The crazy thing is that the fan started to work (intermittently) after that, so she can still use it for brief periods of time before it starts to overheat.
[Nook HD, HD+ Android Development] killersloth:
Yeah, took mine apart enough to get a q-tip in there, hit it with that and an air can to try and clean it. Works sometimes, makes loud noises though, and when it does start to get hot the fan cuts off lol. Same feeling - use it till it dies. Not much else I can do about it at this point. I've taken countless laptops apart but mine is a pita.
[Nook HD, HD+ Android Development] webdroidmt:
@ks

Quick question. Are you considering one final build for Carbon 4.2.2 compiled with the last Carbon source from I guess 8/13 or 8/14? I use HBO GO a lot on my HD+ because of the larger screensize and don't plan to go to 4.3 until HBO updates their app. Just askin'. :D

Based on HBO's track record, since they just finally updated their app to work properly with 4.2.2 on July 23rd, Android 5.0 may be out by the time they update for 4.3. :rolleyes:

EDIT: Just checked Carbon changelog, looks like their version 1.8 from August 1st is the latest and last 4.2.2.

Thanks,

Mike T
[Nook HD, HD+ Android Development] killersloth:
I'll look into syncing up their latest changes from their 4.2 branch.
[Nook HD, HD+ Android Development] webdroidmt:
Thank you, always appreciate your work and attitude here on the forum. Haven't had the opportunity to deal with bokbokan on his roms but you and verygreen make a great dev duo here.

Carbon vs CM10

Hey all, just rooted my HD and looking at ROMs. Some say this is better than CM10 and some say the opposite. Does anyone have some pros/cons or comparisons of the differences between the 2? Including what doesn't work on one or the other?

Thanks.
[Nook HD, HD+ Android Development] swaaye:
B11 build of Carbon has a serious rotation bug that causes extreme UI slowdown eventually and some other instability. Cyanogenmod 10.1 does not have this problem. You should peruse the recent pages of this thread.

I'm on a tablet UI-modded CM10.1 (I don't like the default Phablet UI). 10.2 is out too now but it is not refined yet.
[Nook HD, HD+ Android Development] dbh369:
I see some have posted screenshots, is there another way to get them than standard on nook? V-- n doesn't seem to work
[Nook HD, HD+ Android Development] bpaulien:
There is an option under settings (on the cm10.1, it's under System - Power Menu - then select the "screenshot" checkbox) I imagine that it is in a similar place on the Carbon ROM.

Then all you have to do is press and hold the power button for a second and it will be an option on the menu that pops up.

How are you guys liking Carbon? I rooted my Nook HD but haven't put a rom on yet. I read Carbon has issues and CM10 has issues. Any thoughts or advice?
[Nook HD, HD+ Android Development] swaaye:
How about reading the last few pages of this thread and the CM threads.
[Nook HD, HD+ Android Development] jpisini:
Carbon is very nice. Some people have issues others don't. Try it out and see I think you will like it.

Are you seeing any issues? What are you running it on, HD or +?
[Nook HD, HD+ Android Development] jpisini:
I'm on the HD + I don't notice any really issues. I don't see the rotation bug people mention and my device has only rebooted once in the last several weeks. I am happy enough to say if no new version were released I could use this one for months.

Unfortunately, System UI has stopped

Hi all,

Something odd has begun to happen. I keep getting the message: Unfortunately, System UI has stopped

I've used the unit throughout the day and have had CarbonRom on it for quite some time. Not sure what I need to do. I wiped the cache, but didn't want to wipe data unless that is the only way to fix this.

Thanks for any insight.
[Nook HD, HD+ Android Development] 123421342:
Do you have halo,pie or a theme? All these things could be causing the issue. Try turning each one off for a while and see what fixes it.

---------- Post added at 02:51 AM ---------- Previous post was at 02:50 AM ----------

Advice? Flash carbon and enjoy your new device. I literally have zero problems. After doing a few kernel and cpu tweaks (no OC just governor etc) this thing runs extremely smoothly.
[Nook HD, HD+ Android Development] dmullens:
I have PIE installed, but don't have themes, but I'll start turning stuff off and see what happens. I do have a wallpaper program and I wonder if that is it. Thanks.

I've tried turning off everything I can think of, but I still get the error every second or so. I have CM 10.2 I load off the SD card and it seems okay....but all my apps are under Carbon.
[Nook HD, HD+ Android Development] rqballjh:
Are you seeing this as better than CM10.2 by itself?
[Nook HD, HD+ Android Development] webdroidmt:
I would first try just reinstalling the rom and wiping cache/dalvik. If that doesn't work, I would then wipe system and reinstall both rom and proper gapps, wipe cache/dalvik.

With this, you won't lose your data. Obviously, if you still have problems, a full wipe is in order.

EDIT: I noticed you mentioned a wallpaper program, is it by chance Wallpaper Wizardrii? Great program but a bit flakey. Anyway, if it's not your wallpaper program, try the things I mentioned above.

Mike T
[Nook HD, HD+ Android Development] dmullens:
Thanks. I tried refreshing the rom and it didn't make any difference. I ended up wiping data and now it is working. Isn't taking too much time getting the apps back. Wish I knew what the problem was.

I can't remember what the wallpaper program is. I think it just c copies the wallpaper to the hard drive so I doubt that would be the issue.
[Nook HD, HD+ Android Development] jisoo:
Did you customize anything in the navigation bar? I've experienced system UI crashes after changing the default buttons here.
[Nook HD, HD+ Android Development] dmullens:
I don't think so. The odd thing is, I really haven't changed anything for probably over a week and I had been using it earlier in the day. I turned it on, unlocked it and boom...started getting the errors. Now I just hope they don't come back again ;)
[Nook HD, HD+ Android Development] ms2003:
hoping the new carbon will come soon.i flash back from slimbeam, i think carbon is better some how
[Nook HD, HD+ Android Development] LucaToo:
Have any apps updated.

I have been on holiday for a fortnight and not updated any apps while away. Have now updated apps automatically and system is a lot flakier. Lots of random crashes. Not sure which app is responsible.
[Nook HD, HD+ Android Development] yhli17:
Encountered the same issue. A lot of apps crash. Wipe cache doesn't help. Decided to switch to CM 10.2 0824 and kernel with fstrim. Smoother than Carbon. No issue so far except missing tabletui.
[Nook HD, HD+ Android Development] 123421342:
Fstrim caused bricks just FYI... read the op. Did you wipe data?
[Nook HD, HD+ Android Development] yhli17:
Thank you mention that. I supposed the bug has been fixed ;). I will keep the kernel without fstrim when I flash the next nightly. Last time I did wipe data.
[Nook HD, HD+ Android Development] 123421342:
no problem. not wiping data is what was causing your crashes probably. I will hold out for 4.3 carbon since carbon is currently very smooth
[Nook HD, HD+ Android Development] JeauxAdam:
I have Carbon 4.3 on my phone and its pretty sweet. Missing ribbons at the moment but I think that's being added either today or tomorrow. Look forward to it on here.
[Nook HD, HD+ Android Development] Crazy Chuckster:
I have been searching and messing with this all day. Can anyone tell me how to get the dang Google search bar off of my home screen?
[Nook HD, HD+ Android Development] JeauxAdam:

[Nook HD, HD+ Android Development] Crazy Chuckster:
The launcher that came with it, im assuming Nova. I looked in there and did not see the checkbox to disable.
[Nook HD, HD+ Android Development] williamlaw:
any update will be released ??
[Nook HD, HD+ Android Development] JeauxAdam:
If it is Nova get into Nova settings, desktop, persistent search bar then select never.

If it's a different launcher, just download Nova because it's better. :)
[Nook HD, HD+ Android Development] Crazy Chuckster:
I confused nova with halo. There are no launcher settings in the carbonrom so I may just try nova. I am getting some laggyness and slowdown but I love all the features that carbon has.....

Sorry if I have missed some obvious answer to the following.

Just purchased my HD+ this afternoon. Now the primary reasoning behind this was for class work. However, the diehard inability to stick with a stick android is too much to overcome.

Can someone please verify that rooting, this ROM, etc will not effect such things as ability to run and access adobe digital editions, EBSCOhost, flash video, etc. Cause these are require for my classes and prefer not to do a dual boot setup.

Thanks for all input

Also, what are the installation steps for this one. It's there a preferred root methods.

JB3 (4.3) build under work -- looking for help to fix remaining bugs

Hi guys & gals,

I've been working on getting Carbon JB3 for ovation working. This is obviously based on 4.3 and I'm pulling in the ovation-specific trees from CM10.2.

Although it builds and boots up fine, I'm having problems getting Wi-Fi to work.

The build does have the necessary firmware included and in the right place wl1271-nvs.bin, but the kernel is not loading this because the option CONFIG_WIRELESS_EXT is set to N (when it obviously should be Y).

I'm quite new to the Android build system, and am having trouble figuring out where the kernel config should be set in the source tree.

I would appreciate it if someone who is more familiar with Android build systems could point me in the right direction. As far as I can tell, everything else seems to be working fine.

[EDIT:] Turns out the firmware was in the wrong location. I've moving it to where it should be but loading fails due to size mismatch. I will probably get this fixed tomorrow (Friday).

I'm also including a download link for my current build:

[link to broken build removed, please use below link]

[EDIT2:] OK, everything is fixed now. Wi-Fi, BT, rotation etc. work at least as far as I can tell. New build up at dev-host:

CARBON-JB-UNOFFICIAL-20130912-1634-ovation.zip - 144.52 MB

If anyone would be kind enough to try this on their HD+ and let me know if there are more bugs, I would really appreciate it. Obviously, you will want to have a nandroid backup and do a clean install before you try this out.

Unfortunately, I do not have access to HD/hummingbird, so am unable to build and test for that device.

As soon as I've fixed the Wi-Fi issue, I will upload an updated build and start a new thread for it.

My plan is to follow the Carbon and CM trees with updated builds about once a week, and of course provide downloads for these in xda forum.
