That's because of the low ram on this device, there's not much you can do. Play with zram in performance, it helps a bit. I don't know if it's gonna improve with cleaning of code in future updates. Gnex has 100 megs less ram and it's not as bad (resolution impact maybe?IDK)

The memory is certainly a constraint, but still it is killing apps in what seems to be a very aggressive way, at least compared to my other android devices. The tab 2 7.0 doesn't have more memory, and it doesn't show this effect. I am tempted to install the stock rom again to the see how it works. I also don't remember the same behaviour from 10.1 on my previous hd+, but I had it over a month ago, so might be mistaken.

SEM16G indicates that your eMMC is made by SanDisk. I have the same chip, and have been using the fstrim kernel since 08/24 with absolutely no problems.
[Nook HD, HD+ Android Development] starfighter1948:
Have you got 'allow purging of assets' enabled in the memory section of Performance? In theory this should purge background apps to free up memory for the foreground app you're currently using. I find that with 'allow purging of assets' set the Nook HD+ is more responsive. You could also try using Greenify to force apps to hibernate, when not being used thereby freeing up memory for the app you're using. Another approach is to use Android Assistant to force apps not in use to close, if the tablet gets slow.

Does this ROM allow for VPN setups?

Bump...
[Nook HD, HD+ Android Development] king200:
There are WiFi problems on the nightly builds since ~10/07. That is for the HD and HD+. There is either a very weak, low speed connection and disconnects. I've now tested all the builds since 10/07 and they have the same problem. To be certain, I did a clean install of today's 10/23 rom and the problem occurs. I only installed Speedtest and no other software or settings (other than unknown). The Carbon rom had the same problem and jisoo, OP for that rom, solved it with the in the latest build.

I'm guessing that other devices using the CM 10.2 builds are not having the same problem. How do we go about getting this issue fixed for this ROM? In my reading there is a .bin file that is created when you first setup the first WiFi. Can that file be copied into current builds?

I don't know to do the software but I'm willing to experiment both with the HD and HD+. I'd like to keep heading toward a RC CM 10.2.

i have a question about cm-10.2-20131021-NIGHTLY-ovation.zip,i have installed it on my nook hd+ with the gapps & CWM emmc but reading post number 961 he talked about flashing a tweaked kernel right after installing the rom which i did not do !! do i have to flash a kernel as tablet seems to work ok ? if so which one ? i also flashed my G300 mobile with one of G300 4.3 jb firmwares but i did not flash a kernel !!
[Nook HD, HD+ Android Development] Joe USer:
Actually both stock 2.1.1 and CM support VPN.

In stock, the VPN settings are hidden, so you'll need to download an app that lets you make shortcuts, use it to point to the VPN settings screen.

Thanks Joe. I installed 5 VPN from Play Store and it exposed the vpn settings and I was able to setup a vpn connection.
[Nook HD, HD+ Android Development] jbbandos:
No, I haven't enabled it as I was afraid it would kill openvpn and any other background app. I've found that enabling memory compression gives me a little more stability (openvpn is no longer killed as soon as I start atorrent). I'm already using android assistant to find out which apps are still running in background.

And still, firefox often dies/gets killed with only a couple of tabs open, and atorrent dies as soon as I open anything else. As I wrote before, I have to see if this also happens in stock, it sure doesn't happen on my galaxy Tab 2.

Mine works out of the box, I only had to enable bluetooth, search for devices, and then press the "connect" button in the keyboard. When the Nook found the keyboard I clicked on it, was asked to enter a code in the keyboard, and that was it.

What issues are you having?

Bluetooth Low Energy supported by hardware, not properly configured in software

jira.cyanogenmod.org/browse/CYAN-2494

Android 4.3 supports the central role in BLE with underlying Bluetooth 4.0 hardware. The Nook HD+ has a WL1271L chipset (4.0 + BLE)

processors.wiki.ti.com/index.php/Bluetooth_BTS_files_overview

The current CM 10.2 nightly uses firmware TIInit_7.6.15.bts which should provide BLE support. The bluedroid stack in Android must be compiled with BLE enabled. /system/etc/permissions/android.hardware.bluetooth_le.xml also must be present. This may look something like

github.com/CyanogenMod/android_device_asus_grouper/commit/f2a4cff785ba1070a4be342f2a86b00cd2248445

as the nightly is currently missing the XML file.

Please enable any Bluetooth Low Energy bits at configuration and compile time and I will gladly test on my device. Thanks!

I already have 8/13 installed, how do I upgrade to 8/15? do i just boot into recovery and install the 8/15 rom? thanks
[Nook HD, HD+ Android Development] starbright_:
2 questions here:

How to clean the "internal SD-card"? I couldn't find a entry in CWM and want to have a really clean install.

How is the internel SD card (not a real card, but some kind of a data partition) mounted?
[Nook HD, HD+ Android Development] verygreen:
Huh? There most certainly is the clear notifications icon at least ins the 8/15 build
[Nook HD, HD+ Android Development] SCWells72:
I upgraded to the latest nightly this morning and noticed that my Gmail app had been removed. Easy enough to re-add, but curious. Not surprisingly, I also had to re-flash SuperSU to allow TiBu to work properly. Overall the HD+ is running very nicely on this ROM with the well-known exception of the Kindle app and not being able to run fix permissions. I'm sure all of that will get ironed out over the next few days/weeks, but for now I'm quite happy with the performance and functionality of this device!
[Nook HD, HD+ Android Development] infra_red_dude:
Here is the complete logcat.
[Nook HD, HD+ Android Development] starbright_:
Usually this can be done semicautomatic. In Setting/About Tablet/CM Updates you can download the latest version.

Unfortunatly the update failed, as CWM is looking for the external card, while update ist stored in internal card.

Or has the name be the problem? Can't remember ..

So I copied it and did the update manually. After this a clear Dalvik...
[Nook HD, HD+ Android Development] cfli1688c1:
update manually -- is this booting in the recovery and install the new rom? also do i need to re-install the google apps as well?
[Nook HD, HD+ Android Development] Nucking Futs!:
I asked this in another thread but figured it pertains to this thread as well...

Had issues (most of the Google services wouldn't work & yes, I upgraded to gapps for Android v4.3) going from 10.1 to 10.2 by doing a "dirty upgrade" (only updating thru the Settings app & nothing else) so just did a clean install so it's running smoothly now. For future reference to be on the safe side & since I don't want to lose any data, out of those 3 (factory reset, wipe cache partition & dalvik-cache), is it fair to assume I should just do wipe cache partition & dalvik-cache (in addition to updating thru the Settings app) as long as I'm just updating the same version (example: going from 10.2 to newer version of 10.2)? I'm not referring to upgrading from 10.2 to 10.3, etc.

Does FSTRIM get disabled by just installing 815 over 813 ?

testing on sandisk 64 gig
[Nook HD, HD+ Android Development] bxlegend:
I just usually wipe system and cache when moving from one version to another (i.e. 10.1-10.2) when I want to retain my data and not use an app to restore it. This is usually the process used when carriers do over the air updates. Some partitions, cache for example, are automatically wiped when flashing an update and manual wiping is just over kill. As long as you do not wipe data or factory reset, you will retain your apps and their data.

I don't think FSTRIM is used on the external SD card. It just wouldn't make sense unless you have an SD install (should've been stated if it is so).

Yes that is a manual update. If you are not on the latest gapps from goo.im, then you should update.

An upgrade to lstest gapps from goo.im might be needed for the gmail thing. Super user is working fine on the latest nightly. I have no idea why you've installed SuperSU.

Internal SD card is emmc.

[Nook HD, HD+ Android Development] bpaulien:
When updating the latest nightly version, it rebooted into recovery and then couldn't find the update. It was looking for it on the SD card but it had been saved in internal emmc. Once I manually located it on emmc, it flashed and updated just fine.

Is there any way to get it to look at the internal memory to begin with, so I don't have to do anything manually? Or is it just something I have to do each time?

I don't suppose that there is a way to get it to save the updates to the external SD card, is there? Otherwise I'll have to clean up the emmc every now and then so all my memory isn't used up with nightly updates.

fstrim does not care how is your install working.

the vold would do the calls.

Also sdcard installs have /cache on emmc, so the calls are performed on that as well. (weally, on every filesystem mentioned in fstab that's mounted r/w)
[Nook HD, HD+ Android Development] Sherip:
Works fine for me, have you enabled pie controls for extended desktop and configured pie controls in settings? Have you enabled Extended Desktop in your Power Menu? Mine is configured on the bottom border and when I swipe up on the bottom border, they appear. I've even added buttons to my pie controls (in interface settings, buttons and layout). All working fine.

Not sure why phone / mobile data / etc are even in the nook or nookhd rom bases tbh
[Nook HD, HD+ Android Development] brusyev:

[Nook HD, HD+ Android Development] dmullens:
I've been seriously debating putting stock back on. I was running CM 10.1.3, but I would have random soft reboots, I ran Carbon, ran into similar issues. CM 10.2 hasn't given me any reboots...but it keeps running so slow that it is frustrating. I have an HD+ with the bad chip, so I'm hesitant to run the trim kernel. Wish there was some data regarding the trim kernel and the bad chips.

I posted a page back or so asking if there was some alternative way to speed up CM 10.2 when it gets slower, but didn't get any responses.

There are times when I'm using my tablet to display music (via moblesheets) and having random reboots is not good at all. Having it being frustratingly slow isn't desirable either. I'm at a lost to know what to do. Right now I'm running stock off of the SD card.

If any one has ideas on how to speed up CM 10.2 without the trim kernel, I would be very appreciative.
[Nook HD, HD+ Android Development] superpc:
Google wouldn't implement TRIM in 4.3 if there was an alternative eh? At this stage you either trust the TRIM kernel or bear with the slowness. I chose the former on my MBG4GA chip and *touch wood* it's been running amazing since.

Going back to stock wouldn't solve the problem, there's no TRIM and the device will still get slower and slower over time.
[Nook HD, HD+ Android Development] dmullens:
Hmm... I wondered that, but I thought if the slowness was also an issue on stock, and if the issue with the chip is known, wouldn't a recall, fix to stock, or something be in order?

I wonder how many others with the bad chip are running then trim kernel. It would be nice to have some type of solution that doesn't potentially brick your tablet.

Given time does the CM 10.1 rom have the same issue?

Thanks.
[Nook HD, HD+ Android Development] starfighter1948:
Are we sure that the problem with phone.apk persistently crashing isn't due to an interaction with the trim kernel? If you flash 10/21 and use cyandelta to take you to 10/27 the system works albeit with an noticeable lag at times. Flashing the trim kernel over 10/27 results in the phone.apk continuously crashing, which tends to suggest there is an interaction fault between the trim kernel and phone.apk. However, flashing the trim kernel over 10/21 seems to be stable. The phone.apk itself does not change between 10/21 and 10/27, so what is causing the crash?
[Nook HD, HD+ Android Development] jisoo:
This is the correct answer.

The boot ramdisk (loaded with the kernel) after 10/21 need to include an additional telephony component from the main framework, or the phone process will crash. So either someone will need to compile the trim kernel with the new ramdisk, or revert the change in the main framework and rebuild the ROM.
[Nook HD, HD+ Android Development] starbright_:
what phone.apk you are talking about? i haven't recognise any phone funcionality.

Most people probably will say this is not needed, as it had no GSM/UMTS modem in - but can be used via VOIP as well (without additional app).

So if this is possible, please give me a hint ...
[Nook HD, HD+ Android Development] jisoo:
Even if the device does not have phone capabilities, phone.apk (and some other telephony stuff) gets built in. The AOSP/CM build system has the ability to exclude only a few applications -- mainly the LED/torch and camera -- from being included in the ROM for a specific device. If you want to leave out phone/mms/other capability, you would need to modify the universal vendor/cm definition files, but any changes in these would apply to all devices built for that ROM.

So in short, for "officially supported" devices, you are going to see some features/changes which are not desirable for a specific device, but which have to go in because of wider device support. That's why most ROMs really best support Nexus devices (and some other very popular devices like the Samsung Galaxy S handsets), and any other device which have some hardware quirks (in particular our Texas Instruments Nooks) may suffer from these changes.

Fresh flash of Rom once in a while might help I guess.
[Nook HD, HD+ Android Development] leapinlar:
Or maybe a nandroid backup, followed by a format 'data and datamedia', (that actually formats /data instead of erasing it) followed by a restore. Of course that wipes your /sdcard too which a nandroid restore does not restore.

But I have no idea whether that really helps with nandroid trim.

If you're referring to my post, I used Titanium Backup. I did have to search for the full file name (com.android.phone) within TB. My only reasoning was that I never use any phone functions on a tablet, so why not try it? So far, the trim kernel/lagfix works and I haven't seen any side effects. Be careful which emmc you have, of course.

There are other "bloat" freezers in the app store.

[Nook HD, HD+ Android Development] TeutonJon78:
Nice to hear from you verygreen.

The only big issue is that the trim kernel started causing conflicts with phone.apk due to some changes. It can be worked around by freezing the apk, but we need a new kernel build with TRIM (or even better, some way to get it enabled back in the build based on chip type/desire to risk it).

I think most everything else is working. leapinajar has been very helpful for people.
[Nook HD, HD+ Android Development] brusyev:
Thanks Verygreen. Is there a chance we could get an updated trim kernel to work with the latest nightly's? Currently the only way to make it work is to freeze phone apk with Titanium backup...
