Has it been confirmed that TRIM is turned off so as not to cause the brick bug?
[Nook HD, HD+ Android Development] MugenMad:
Love the Build & its Proformance Great Job Any word On BT..
[Nook HD, HD+ Android Development] cfli1688c1:
very speedy. good work
[Nook HD, HD+ Android Development] MugenMad:
Morning is there a latest build of slim bean I see there Wip Final anything new for Nook HD+
[Nook HD, HD+ Android Development] killersloth:
Slim has has fixed BT on their end I believe.

Will check it out and update if it works ;)

Later sometime though. Busy busy.
[Nook HD, HD+ Android Development] rushless:
Questions to Killer please:

Is Trim disabled?

What changes have been done to this rom in comparison to 10.1 that would make it faster? Seems most issues we have are more hardware limitation related then firmware, but would like to be wrong!

Is bluetooth working?

How is battery bleed in sleep mode with wifi set to always on?

Thanks!
[Nook HD, HD+ Android Development] cfli1688c1:
How do I install this?

I try to install over 10.1, but when it boot, its struck at the slim flashing logo.
[Nook HD, HD+ Android Development] killersloth:
Pulled in updates and building now, hopefully with working BT.
[Nook HD, HD+ Android Development] iomthd:
Awesome, been looking forward to this!
[Nook HD, HD+ Android Development] killersloth:
Getting 12-15kb/s upload on this WiFi, haven't tested yet and can only test on ovation now...
[Nook HD, HD+ Android Development] MugenMad:
Sounds Great I Can't Wait
[Nook HD, HD+ Android Development] killersloth:
Just tested on ovation, Bluetooth doesn't work still :(

Good news: dho and nuclearmistake are working on fixing up strict aliasing errors for ovation. Helps a lot with getting this device setup for other developers :)
[Nook HD, HD+ Android Development] jpisini:
Thanks for trying it is appreciated
[Nook HD, HD+ Android Development] MugenMad:
Any links to the updated Slimbean Thanks
[Nook HD, HD+ Android Development] wktra:
I'd love an update, too!
[Nook HD, HD+ Android Development] webdroidmt:
Hey KS, I'm a little confused here. :laugh: Are you talking about Slimbean, Vanir, (nuclearmistake and DHO) or just in general with ovation? Speaking of Vanir, are you thinking of becoming a maintainer for them? ;) I wouldn't mind that at all. :D

Mike T
[Nook HD, HD+ Android Development] killersloth:
I don't have the time or properly functional computer to try and maintain a device, running test builds all the time and such. The good thing is that the people behind vanir (dho and nuclearmistake) are working out build errors for ovation, which means one of them has this device too ;)

Hopefully they don't get hung up at the weird hwc or whatever errors they were causing strange rotation and orientation.

Also, I have the latest build on my laptop and I can upload it if desired. Bluetooth doesn't work, only thing I tested.
[Nook HD, HD+ Android Development] webdroidmt:
Yeah I'm hoping those guys don't give up on the Nook. Seems like every rom that uses any of the AOKP framework has the rotation issues. And, we also have the "cool" borked bootanim. :laugh:

Speaking of rotation issues, I've actually been using your rootbox build now for about a month. I need 4.2 for HBO GO until HBO gets their act together for 4.3...I still say we may have 4.4 before HBO fixes 4.3. :rolleyes: Aside from a few little quirks, rootbox runs well for me and gives me all the functionality I need or use.

Anyway, Vanir is a very solid rom on most devices, I hope we get to see it on the Nook. Oh and I know I'm always "electing" you as a device maintainer, it's because you're that good! :D I know RL's got you busy, so do what you gotta' do and thanks for all your contributions here, it's appreciated. See ya' around.

[Nook HD, HD+ Android Development] jisoo:
The rotation issues are caused by the rotation sensor giving out inaccurate readings. There seems to be a few different ways to read rotation, and a lot of these fail to detect the actual rotation on ovation & hummingbird (CM has added a method to compensate for the inaccurate readings).

The most reliable way would be to compare display width and height (if width > height = horizontal/if height > width = vertical), but that's not the way AOKP decided to do it... I think it's telling that Halo (which is from PA) has no rotation problems that I've been able to find.

Speaking of the bootanimation bug, does anyone have any ideas what causes this? It seems like the display dimensions are detected wrong at first, though this gets corrected halfway through the boot sequence.
[Nook HD, HD+ Android Development] webdroidmt:
That sucks about AOKP but nevertheless good info, thanks. As for the bootanim glitch, this is/was also a problem on the Galaxy Tab 2, that I believe started with CM10.0 but kernel dev ketut.kumajaya pretty much solved the problem. How he did this is beyond my pay grade but it does work.

Here's a link to his Blackhawk Next kernel and his source in the OP if you want to take a look. http://xdaforums.com/showpost.php?p=41583846&postcount=1

Btw, since KS has stated that he is unable to be a maintainer, maybe you would consider being a maintainer for Vanir if those guys can get it fixed for Ovation? :cowboy: :D I have spoken to Prime Directive, one of the lead devs and they are always looking for new device maintainers. Plus, I would think you have a good step up on them for Ovation...so, just a thought. I lack the skill or I would gladly do it.

Mike T
[Nook HD, HD+ Android Development] jisoo:
Regarding the bootanimation, the actual code is part of the frameworks/base package (frameworks/base/cmds/bootanimation). This c++ code loads the images (in-built, or from a zip archive in /system or /data/local) and puts them in the framebuffer. Now, I'm not a programmer and can't read the source code (I can barely wrap my head around java) so I'm not sure where the bug could be.

If anyone ever comes across a ROM with a working bootanimation, we could probably compare the implementations to identify the bug (or find a way to hard-code the correct aspect ratio). As far as I can tell, this bug has been present in all custom ROMs for ovation, so I'm not too hopeful to find an easy fix.

I appreciate your suggestion I become a maintainer, but I'm not sure I would be the right person for this. My plan was to try my hand at building Pac-Man next (assuming there's no major bugs uncovered in the Carbon builds).

In general, I've found that putting together and updating ROMs is not overly complicated once you understand how the source code is organized (having a background in Linux helps of course).

If there is a custom ROM that already has good support for tablets, we should be able to get a build up in a day or two (as there shouldn't be too many bugs in the source code to start with). However, I'm starting to notice that Carbon for instance is not maybe the best suited ROM for tablets (even their official Nexus 10 builds have serious navigation bar issues), so I think we should first figure out which ROMs support tablets well and then start working on an unofficial build for that.
[Nook HD, HD+ Android Development] killersloth:
Paranoid android boot animation was correct but it was in landscape orientation all the way through boot. Then the display was showing one orientation but touchscreen was detecting input as if it were flipped a different direction.

#nookproblems

I probably deleted that build to make space on my laptop but the boot animation looked so clean in landscape. Otherwise it was completely unusable with that touch orientation bug.

Once strict aliasing bugs are worked out pretty much any ROM built from source for any tablet should be simple to build for nook HD/+
[Nook HD, HD+ Android Development] adwait.bhandari:
PapaSmurf151, one of the admins for PAC-man ROM was looking for a device maintainer for ovation. http://xdaforums.com/showthread.php?t=2406258

Any thoughts on this?

Also IMO the fixing of boot animation doesn't really matter as far as normal working of the ROM is concerned.

[Nook HD, HD+ Android Development] hast:
After trying all the other roms here, including Unofficial Carbon 10--20 and Xperia, I keep returning to this one. Hopefully 4.4 offers us some speed improvement.
[Nook HD, HD+ Android Development] smithmal:
Quick question: The instructions above indicate the CM ROM should be unzipped and you will get a 4GB image file for flashing using CWM. When copying the slim 4.3 ROM (slim_ovation-ota-eng.sloth) to the SD card, is it necessary to unzip/unpack first and then copy it over using WinDisk (as the instructions indicate) or should we just copy the zip file "as is" to the SD card and flash it using CWM?

Thanks,

smithmal
[Nook HD, HD+ Android Development] bpaulien:
Copy the zip as is. Then when you are in CWM you will choose to 'flash zip' (from either internal or external memory) and then you select that zip file to flash.
[Nook HD, HD+ Android Development] coolmen777:
Auto brightness doesn't work? Also, can't seemed to turn on Bluetooth (thought I read someone said it was fixed). Just confirming, a new Nook HD+ owner here.

Also, when attempting to add a new user, got many various FC error for Google related apps. Not sure why (using Nova launcher).
[Nook HD, HD+ Android Development] smithmal:
Thanks. I thought this was the case, but wanted to make sure other newbs more newb than me didn't go about trying to extract the ROM first and then try to flash it in CWM (has the original instructions state).

Could someone verify this? BT functionality is important to me.

smithmal
[Nook HD, HD+ Android Development] bpaulien:
There is no sensor for auto brightness on the device so no, that feature of this ( or any other ROM) will not work
[Nook HD, HD+ Android Development] coolmen777:
Thank you, didn't realize that.
[Nook HD, HD+ Android Development] smithmal:
Confirmed. BT will not turn on with this ROM.

smithmal
[Nook HD, HD+ Android Development] killersloth:
Yeah Bluetooth is borked, something with the hardware trees slim uses I think.

Just fixed the screen on my phone, it got run over weeks ago lol couldn't see anything on the screen. Tried so hard to blindly turn on WiFi tether toggle then it stopped accepting touch input completely.
[Nook HD, HD+ Android Development] smithmal:
Issues noted:

- BT won't turn on

- Wake is a little flaky when using the magnetic sleep function after it's been sitting asleep for a while

- User accounts don't work; when setting up I get lots of google process errors and it won't let me boot into any user except for default user.

Thanks,

[Nook HD, HD+ Android Development] alxndrs:
I'm also experiencing an issue with my auto rotate. I've tried different settings in Display and Accessibility but no go. This is a very nice rom, hope to get it fixed in next update.
[Nook HD, HD+ Android Development] smithmal:
I've tried just about every ROM now for the NookHD+ and this is far the most responsive. If BT could just be functional, I'd be a happy camper.

smithmal
[Nook HD, HD+ Android Development] 320flyboy320:
Anyone know if this ROM is 8/15 nightly or earlier (I assume if it's post 8/15 then trim should be turned off)?
[Nook HD, HD+ Android Development] smithmal:
Sloth,

Any chance the Slimbean devs would be adopting the HD/HD+ and/or could look into fixing the BT issues? This is really the only thing holding me back from making it my daily ROM choice. It is still my favorite for responsiveness so BT functionality would but the "cherry on the top."

smithmal
[Nook HD, HD+ Android Development] bpaulien:
I hear you. I came back to slimbean after trying out the Liquid Smooth ROM because this one is still way more responsive. I am fortunately I'm not using BT so that isn't an issue me.

I also wish that SB had the ability to use multiple users accounts (not working ATM).

Bluetooth Question

I'd like to try this ROM, but I do, sometimes, use a Bluetooth keyboard. Based on the discussions I've read here, should I assume that Bluetooth is not working at all in Slimbean? In other words, I would not be able to connect my bluetooth keyboard?

Thanks,

[Nook HD, HD+ Android Development] smithmal:
Thanks for providing this. Can anyone provide a quick tutorial on how to install this? Also, are there any additional advantages to this kernel other than trimfix? Someone above mentioned OC. If using this kernel, can OC now be applied using a CPU OC app that require root?

Agree with Slimbeam's responsiveness as voiced out in this thread, I have it in both an hd and hd+, and it is as smooth and responsive as my 1st gen Nexus 7. Thanks to the developers, and hope that they continue to update to account for some issues indicated in this thread. For the most part, it is my everyday rom now, since I don't use bluetooth. Please don't change SB's unique advantage over other roms which is it's simplicity and responsiveness.
[Nook HD, HD+ Android Development] SteveCoops:
Is the build from 15 August still the one to use for Slimbean?
[Nook HD, HD+ Android Development] smithmal:
AFAIK yes. We have the build #1. There is a build #2, but it hasn't been ported to the HD/HD+. Slimrom devs are now actively working towards implementing 4.4 (KK). I wish we could get this tab to be officially supported, but we would need someone to volunteer to be a "device maintainer."

According to Slimrom:

If you have a device we do not currently support, and you want to officially maintain it as well as keeping it up to date with our device trees, contact us and we will work with you to make this possible.

Not sure if killersloth has time to do this and if not, if being a maintainer requires some significant dev experience (i.e. linux experience).

smithmal
[Nook HD, HD+ Android Development] SteveCoops:
Thanks for that. I wouldn't have the dev experience to be the 'device maintainer' :(

I think this is the only Android ROM I've not tried yet, so installing now :)

Hi, I installed CM 10.1 and it's a bit laggy - better than stock but still slow. Could anyone please tell me:

1-how does slimbean achieve its smoothiness/better speed/performance? Has it been optimized, or has crap from AOSP or CM been removed? (I thought AOSP&CM were mostly crapless!)

2-I have the affected EMMC chip but with revision 6, and I'm willing to risk it. The slimbean kernel has trim on or off? Any recommendation?

Thanks!
[Nook HD, HD+ Android Development] smithmal:
I'm not wise enough in "dev speak" to answer your question as to why Slimbean is a more responsive ROM vs. "ROM x." My assumption is that it is better optimized from a I/O level which reduces overall lag but I don't know that for sure.

To your TRIM question. The stock Slimbean ROM in the OP is without TRIM optimization. There is also a TRIMfix kernel which can be flashed after flashing the original Slimbean ROM. I can't say that it has improved things with my HD+ however, it is my understanding that TRIM wipes away all unused memory blocks. Unused memory blocks become more of an issue the more you use your tablet. Since I'm constantly switcing out ROMs to test and therefore wiping my memory each time, TRIM issues haven't reared it's ugly head. I can say that the TRIMfix kernel hasn't reduced responsiveness so I see no reason not to use it. The other benefit to the TRIMfix kernel is that for the HD models, the CPU can be overclocked to 1.5Ghz. The HD+ models are already @ 1.5Ghz. I'm seeing an increase of 3,000 (vs. stock Nook firmware) on Antutu running Slimbean with the TRIMfix kernel.

Just remember the following, when choosing Slimbean ROM/Kernel versions for your Nook:

The NookHD ROMs and Kernels are denoted as "hummingbird" builds

The NookHD+ ROMs and Kernels are denoted as "ovation" builds

The reported bugs for Slimbean so far are:

BT non-functional

No multi-user support

Thanks,

smithmal
[Nook HD, HD+ Android Development] gotbass:
very useful post smithmal.

i appreciate that i may just be being lazy in finding the answer to this.

but, i have a HD and dont fully comprehend this TRIM my device may or may not possess?

how do i find out and is there anything i can do to my device once i have found out to make it more responsive?

thanks
[Nook HD, HD+ Android Development] smithmal:
The native Nook firmware nor "plain" Android OS does not contain TRIM fixes. It is a bug with the Android OS in which unused memory blocks continually build up the more you reboot your tablet. As these unused memory blocks increase over time, you will notice lag. There are apps on the market that may, or may not work with stock Nook firmware (see "lagfix"). Devs have built kernels which automatically removed unused memory blocks (i.e. "trim" your memory).

If you are planning on flashing the Slimbean ROM to your HD, the TRIMfix kernel you would want to flash the "Nook HD" version hyperlinked in this thread (click "Show Content" to see the DL link).

smithmal
[Nook HD, HD+ Android Development] :
Sorry for the noob question, but does SB come with a built-in updater like CM?
[Nook HD, HD+ Android Development] smithmal:
The NookHD/NookHD+ is not officially supported by SlimROM so no, you cannot automate ROM updates.

exFat microSD card support

Thought I should mention this for individuals trying to use a 64GB card with this ROM....

The Slimbean ROM is built around a version of CM 10.2 that does not natively support the exFAT format (which is the default format for SDXC 64GB cards). When first inserting a SDXC card into the NookHD+ I got the message "Damaged SD card; format necessary."

Both SB and CWM were unable to format the card. The reason is that exFAT is a two partition system which can't be properly read by this ROM. ATM, you will need to re-format your card to a single partition that is FAT32 in format.

In order to properly format your card to FAT32 you will need:

1. A SD card reader compatible with SDXC cards (note many older card readers don't support this; if you try using a card reader that doesn't have SDXC support the best you will be able to format your card to is 32GB).

2. EaseUS Partition Master Home Edition

3. Follow directions from this thread.

Please note; this procedure will wipe the card's exFAT format and change it to FAT32. The benefit is that you should now have a full 64GB storage capacity with your card. The negative is that since it is now FAT32 it cannot read files over 4GB (which exFat allows for). I believe new versions of SlimROM allow for exFAT compatibility however we do not possess this with the current Slimbean build for the HD/HD+.

If anyone has any work arounds to get SDXC cards working with this ROM using the exFAT format, please let me know.

SlimKat for NookHD/HD+

killersloth,

SlimROMs released a Android 4.4 version (SlimKat). What do you think the chances are of porting this to the NookHD/HD+? I'm still using Slimbean on my NookHD+ and loving its responsiveness (wish it had BT functionality, but I can live without it).

smithmal
[Nook HD, HD+ Android Development] asksmity:
I too would love a new version of slim, regardless of 4.3 or 4.4. The responsiveness is incredible on nook but the Bluetooth and couple of other flaws kill it for me.

I can compile, but I am weak in the bug fixing department. Also, since this is a non supported device I have no idea where the device repo is. If anyone knows where i can get the device files I am willing to TRY a build.
