These changes make little difference to kitkat. My testing found it worked best with 128M swap. I was using the older lzo compression.

We had horrible video bandwidth problems on the bn encore (omap3). We obtained much better performance by using 16 bits per pixel rather than the default 24 bits per pixel. Steven Luo (steven676) made a nice user settable toggle. I made a simpler patch. I haven't noticed any change under kitkat or ics but we are not so bandwidth limited there. It might help with lollipop. Here's the kernel patch

Thanks, amaces. I don't think this is a kernel problem because there is no dontpanic file or last_kmsg log. I have a zip of three tombstones from today. From the 00 tombstone it looks there is some problem with a google newstand process. (I have a newsstand widget.. I was not reading when the crashes happened) . I have a zip of all the other logs also, but I think the tombstone are probably the most useful right now.

Hi

I installed the latest version and I am impressed with it. Nice work there. I had some crashes, reboots which are expected. MY question is about performance. Are there any tweaks that I can do to improve the performance in general a bit? I use the interactive scheduler.
[Nook HD, HD+ Android Development] twiztid_:
I've been having an issue with built-in Browser on the current stable 5-30 (and an experimental, 5-25 maybe?). If the tablet sleeps, with ANY tabs including the default homepage, when I relaunch browser the previous tabs I get the following error:

net::ERR_NETWORK_CHANGED

It doesn't seem to be affecting, or caused by, my connection as it happens only on existing tabs, and doesn't affect the home page -IF- browser was closed by closing all tabs so homepage tab needs to be "created".

Anyone else having this issue?

Also have had a long standing issue with Most Visited homepage, due to F2FS. Seems it can't read its internal file when the storage (/data I think) is F2FS.

Hi,

I've updated TWRP and flashed the ROM OK but I cant seem to get gapps working at all. I've tried 4 different versions and only 1 version has actually installed via TWRP. When I boot the rom and start the play store it force closes.

Can any one help me out?
[Nook HD, HD+ Android Development] twiztid_:
What gapps have you tried? They have to be 5.1 gapps, 5.0 and 4.x will not work.
[Nook HD, HD+ Android Development] scoopsy:
Ive tried TK gapps mini & micro 5.1.1, pa gapps micro 5.1 and banks dynamic gapps

The banks one is the only one that will install successfully however the play store fc's when launched
[Nook HD, HD+ Android Development] twiztid_:
I use PA Pico gApps, and never had an issue. Did you dirty flash? Maybe you have some files that are causing problems. I wipe /system, /data, /cache, and /dalvik when moving to a new ROM or having issues, and /system + caches when I need a semi-clean upgrade. Haven't had an issue following that so far.
[Nook HD, HD+ Android Development] belfastraven:
After I tried re flashing the 5/24 rom (which always worked for me) and started getting the same issues, I wiped cache, dalvik and data, and reflashed the 5/30 hummingbird rom. so far so good. I don't quite understand what became corrupted on both of my systems... which are not running all of the same apps. I see how things go for the next couple of days. Thanks again.
[Nook HD, HD+ Android Development] scoopsy:
I was just doing a standard wipe via TWRP. Wiping the system as well got it working with the PA gapps.

Thanks for you help.
[Nook HD, HD+ Android Development] twiztid_:
Of course, as seems to always be the case, once I posted about the "net::ERR_NETWORK_CHANGED" error, it went away. It did not happen yesterday or today at all. I do use a Hosts based adblocker (AdAway), and reloading the errored pages would continue to give me the error.

If it happens again, I'll try disabling the adblocker, thanks.
[Nook HD, HD+ Android Development] techdudepro:
Wow, THANK YOU [MENTION=4473900]amaces[/MENTION] FOR YOUR AMAZING WORK. The 5-30 hummingbird build is a lot smoother for me. The builds just keep getting better and better!!! Awesome job!!!!!!!!!!!!!

chrome issues w/6-4 experimental build

The new experimental build seems REALLY fast switching tasks, etc. Unfortunately in my setup chrome becomes mostly unusable.

On certain sites some "rectangles" on the screen will keep reloading or blinking on and off. Not really the flashing we have had with some other issues but kind of similar.

Like I said, good in many ways so hopefully can use some of this or figure out what is going on with chrome.

Thanks MUCH for everything!!

6-4 problems

Seemed ok till I tried videos. Youtube would not play any video, same with netflix. MX Player only works with non HD videos even then poor rendering. I have reverted to 5-30 where they all work quite well. For me the DMA means Doesn't Media Anything.

[Nook HD, HD+ Android Development] techdudepro:
Okay, 2 bugs on the hummingbird 5-30 build (minor, happened only with 5-30 build)

1: when I open a bookmark from stock browser that is on the home screen, trebuchet crashes, and opens up to the recent apps menu, then I can select which browser to use (I have Firefox also). Still happens even when stock browser is used to open the bookmarks on the home screen by default.

2: when in battery saving mode (from settings), and if I open an app group from the home screen, the apps in the group don't show (invisible). Then, when I go back to the main home screen, none of the icons show. The only way to show them again is to long-press the home screen (and show widgets) which brings back the home screen icons.

Edit: 1 more bug:

Can't see battery percentage in battery icon, if enabled. The battery percentage text is white, which is the same color as the battery icon itself, thus the reason for me not being able to see the percentage in the battery icon.
[Nook HD, HD+ Android Development] TBueno:
In every device I've ever run CM, Trebuchet has always been a source of strange bugs. Check JIRA for these ones, they're probably being worked on already. I'd bet these are not "5-30 build bugs".

By the way, I've never seen such a buggy version of the Browser. No anonymous mode, for starters. "Find in page" has a graphical glitch, text you enter is white on white background, thus invisible. Long press on an image brings options covered by a thick shadow, it's barely readable. My only sudden reboot on 05-30 so far was triggered by it. WTF... is this AOSP or CM?
[Nook HD, HD+ Android Development] tj2003:
I agree with you on Youtube. Do not have Netflix.

Mx Player Pro is working fine with 1080p movie from sd card. Amazon Instant video plays hd movie without any trouble. Verizon Fios mobile app plays any hd or sd channel without any problem. This is with 06/04 experimental ovation.
[Nook HD, HD+ Android Development] kdejong2012:
Apologies if this has been asked before but I've read through the thread a few items for specific install instructions. I'm currently running CM10.2 and cynaboot.

I have flashify installed and wanted to confirm install instructions -

1. Download ROM and GAPPS

2. Install TWRP via Flashify

3. Install ROM and GAPPS from EMMC via TWRP
[Nook HD, HD+ Android Development] tebra:
You are all good.

Don't forget to download gapps for android 5.1. And format cache, davlink cache (and data)
[Nook HD, HD+ Android Development] N0he:
I'd recommend downloading the TWRP version in amaces' folder, rather than downloading TWRP through Flashify. amaces is our expert here, you can't go wrong with whatever TWRP version he provides.

Also, jumping from 10.2 to 12.1, you should do a full wipe.
[Nook HD, HD+ Android Development] js290:
usb debug?

Anybody else having problems with usb debugging? Adb devices shows nothing connected. I've had this same problem with ovation and hummingbird on official CM11. Same problem now with cm-12.1-20150530-UNOFFICIAL-hummingbird.
[Nook HD, HD+ Android Development] kdejong2012:
Thanks to N0he and tebra for the quick replies. I did factory refresh, flashed with amaces' TWRP, and flashed PA Pico Gapps and everything is flying.

Thanks to Amaces for the awesome rom. I running the Google Keyboard and did not turn of HW overlays, I have no issue so far.
[Nook HD, HD+ Android Development] danrb40:
Is there a TWRP for hummingbird somewhere? I feel like I missed it.

Edit: Nevermind, I found the "box"!
[Nook HD, HD+ Android Development] TBueno:
Anyone running 0607-ovation yet? Care to share first impressions?

[edit] Just because I didn't do a backup this time, Chrome is giving me some ugly flickering...
[Nook HD, HD+ Android Development] sasmith-129:
HDMI issues

Thanks for your hard work amaces -- this is a great ROM!

I've been using the published ovation builds over roughly the last month with only occasional hiccups/restarts similar to what have already been reported and discussed.

However, today, while away from home, I tried using the HDMI output for the first time and discovered there's no audio over HDMI. Also, the video is upside down although that can be corrected by rotating 180 degrees. I tested with MX player, VLC, and the standard video player, all with the same results. I can't rule out the TV I'm using although a Dish receiver works fine using the same HDMI connection.

This is probably a low priority for you but thought I'd pass it along in case someone else knows of a workaround.
[Nook HD, HD+ Android Development] twiztid_:
It feels faster than 5-30, but it's flickering is FAR worse. On 5-30 I could deal with the flickering and finish typing, but on 6-07 the flickering would not stop and I had to hold the power button to force power off. I turned Hardware Overlays off and have been happy with it.
[Nook HD, HD+ Android Development] TBueno:
Yes, it's apparently snappier. Only had time to experience flickering in Chrome, other browsers seem fine. But I'd rather not compromise so I fell back to 0530, my golden standard so far.

Some of the tweaks that improve graphical responsiveness are probably causing the flickering, I'd guess.
[Nook HD, HD+ Android Development] danrb40:
Hummingbird running smooth like butter here. Didn't encounter any problems during setup or the hour or so I was downloading apps. Haven't tried Netflix or hulu yet, which is what I will mainly use it for.

Fantastic freaking job!
[Nook HD, HD+ Android Development] bluecopper:
GM! I I was running the CM M12 release on my HD+ for a while and decided to try out the May 24th nightly. I started having some touch issues that i had before the M12 release. The touch would would randomly activate at different areas, which was very annoying. Decided to look into lollipop release and found this one and installed Saturday. I'm however still having those touch issues and the tablet has rebooted while in use about 4 times between saturday and today. Going to update to the latest release now and see how it goes. Any ideas about the touch issues?
[Nook HD, HD+ Android Development] tebra:
Also have the touch issue on my HD. That bug was even there with the stock rom. I think it is a hardware issue :(
[Nook HD, HD+ Android Development] amaces:
I certainly hope so… Honestly, recently I've only pushed to my GitHub repos rather than submit to CM Gerrit for review. There are too many commits, and the process takes too long, but mostly I need to make sure everything is actually a stable improvement. Also, no point pushing too hard while our few longstanding bugs (e.g. HW overlay underflows, digital mic capture, etc) remain… Yes, I also wondered about acclaim, but it's likely that chrmhoffmann is actively using his, while Hashcode has three generations of Amazon devices, Motorola stuff, etc, to deal with, so totally understandable.

Yup, the interaction between the new ION/memory allocation backend and the tiler does that on the early DMA-buf K3.0; it's incomplete, but after working on it for a few days, I was excited that it actually boots. It was just a taste of how much better K3.4 could be, if we ever make it run on the HDs.

Yup, as mentioned when I uploaded it, everything video that is HW accelerated (i.e., sent through the OMX->Ducati/IPU coprocessor) will not work on that highly experimental kernel, but what does work, is promising in my opinion. That's useful incentive to continue working on K3.4, and don't plan to make that experimental K3.0 default on the regular builds.

Yup, stopped using Trebuchet years ago. By the way, [MENTION=6626970]techdudepro[/MENTION], I noticed a few related commits last week, so maybe the 06/07 build works better. Regarding the Browser, I thing Google more or less gave up on it; the AOSP version is even buggier than what we get on CM :( Anyway, this set of bugs is part of the rough world that is CM12. Somehow, the Nexus 5 nightlies are equally buggy and inconsistent, and that's a supposedly well supported device…

Fluke? I use ADB a lot, and it only happened once, months ago; if re-pluging the cable or rebooting doesn't fix it, check Developer options.

Try the test boot image in the ovation folder with 06/07 (may also work on 05/30); some of the bandwidth prioritization code I back-ported from K3.4 needs more work, so I've removed it for now.

Huh, I wonder if the lack of audio over HDMI is a new bug, or something hidden till now. I don't have the HDMI adaptor to test it, but it may be related to the class of audio bugs unearthed with the transition to new ABE firmware/digital stuff. Either way, I'd say it's medium priority so hopefully we get it to it after the other kernel stuff settles.

If the 06/07 build feels unstable, try flashing the boot-ovation-test.img on top of it.

Definitely a hardware component to the digitizer bugs, although they happened less often recently. In my case, I would put the device to sleep for a couple of seconds, then resume, and the phantom touches would disappear.
[Nook HD, HD+ Android Development] bluecopper:
OK thank you. Will try that. I also had the touch issues with stock nook is too.
[Nook HD, HD+ Android Development] amaces:
Heads up, Hashcode has just turned on CM12.1 nightlies for some KFire devices (jem and tate, similar to ovation and hummingbird, respectively): http://review.cyanogenmod.org/#/c/100435. Maybe we're not far behind…
[Nook HD, HD+ Android Development] mr72:
Has anyone gotten Screen Casting to work with this ROM? If not, would it be too much to request it? I think it works on CM12.0 on Ovation. With a 3rd party app I was able to at least get it to show my Chromecast as a target and try to connect, but it immediately disconnects and never casts the screen.
[Nook HD, HD+ Android Development] TBueno:
Does that mean more chances of a 3.4 kernel port or maybe your [awesome] builds are making their way to "official" CM?

---------- Post added at 06:13 PM ---------- Previous post was at 05:58 PM ----------

It works for audio only (blank TV screen) in 0510 and 0530-Ovation.
[Nook HD, HD+ Android Development] mr72:
Well that stinks since what I want to use it for is video only (ebook).

Any news on this? Plans?

Root Access

Not to interrupt, but I lost root access after flashing this rom. Anyone know of a way to become rooted again?

Apologies if this has be mentioned before.

Thanks
[Nook HD, HD+ Android Development] king200:
Try Settings->Developer Options->Rootaccess-> Select Apps
[Nook HD, HD+ Android Development] js290:
Knowing me, that's certainly possible. Though, I've had the same problem now on two different ovations and one hummingbird. Must be some setting I'm missing. I know USB communication is working because the device filesystem mounts on my Xubuntu computers. And, the device itself even indicates USB debugging connected. But, adb devices from my xubuntu systems all show nothing when ovation or hummingbird is connected. All other devices work just fine. FWIW, I opened a bug report a while back.

I've been running the Candy5 build on jem.

Skype/Hangouts problem

I updated from CM11 to CM12 -0530 and when i make a skype or hangouts call the sound is choppy or i can't hear nothing at all . The mic is working though .

Is this a common problem with CM12 ?

Everything else is working perfectly.
[Nook HD, HD+ Android Development] jt61:
can someone explain in a little more detail what the above means? just un-zip, replace the boot.img file in the zip with that one, re-zip, and re-install?

thx,

-John
[Nook HD, HD+ Android Development] prsa01:
I

I'm far from an expert, but, what i did based on his post:

Flash 6/07 ROM

Then flash the boot image file (twrp lets you flash an image)

This seemed to work. I ended up with similar isssues to 6/04 rom, though not quite as severe, so went back to 5/30 which has been VERY solid for me
[Nook HD, HD+ Android Development] jt61:
thx - I think I'm going to try that (5/30)

I went from 5/23 to the experimental 6/4 DMABUF and then 6/7, but solid sounds good

I have side issues that cross versions, so should probably post those separately, but in case anyone here has any hints, they are (succinctly):

* won't stay powered off - shutdown shuts down but immediately re-boots

* battery level randomly appears to suddenly drop to 1% - I say apparently because it will keep running for quite a while afterward, and sometimes re-booting will re-set battery level to something reasonable like 65% or whatever

both are very annoying, but like I said, I saw both issues with earlier versions (e.g. 10.1 and 11), so probably not appropriate for this thread

-JT
[Nook HD, HD+ Android Development] twiztid_:
I flashed the boot.img file on top of 06-07 and all I can say is wow.

Probably the fastest build of lollipop to date, and the flickering is all but gone so far. I got some minor flickering while typing in a URL in Browser, using 5.0 stock keyboard (don't care for 5.1s layout) but thats about it. I got 3 maybe 4 flickers total when typing in google.com and imgur.com, but i typed some comments and this entire reply without a single hint of a flicker.

:highfive: Amazing work, amaces!

To anyone who has never flashed a boot image under TWRP (like me):

Hit the install button, then the Image button (bottom right corner) to switch from zip to img. Just be sure to select boot not recovery. After that I wiped cache and dalvik just to be sure, but I have no clue if its needed.
[Nook HD, HD+ Android Development] TBueno:
Hangouts trouble had been reported before. Just tried Skype here and it's just crackling... bummer. We're running out of telephony options.

[edit] WhatsApp can't handle voice calls either, but it does voice messages, if you master the 2-second delay it takes to "open" the mic, discussed here. And Sound Recorder works. Something's funny about audio.
[Nook HD, HD+ Android Development] TBueno:
Tried the same, but I still get artifacts (white rectangles) on Chrome.

Apart from that, everything seems faster, Lollipop's fancy animations are snappier and smoother. Task switcher and Newsstand are sensibly faster.

Memory management seems better, sometimes falling back to home screen from Chrome doesn't trigger a redraw, and redraws are visibly faster.
[Nook HD, HD+ Android Development] danrb40:
My HD has to be plugged in to use it. I'm not sure why. It all started when I upgraded to cm11. Could be something wrong with my battery. The second I unplug it, it shuts off and it won't turn on unless it's plugged in.
[Nook HD, HD+ Android Development] twiztid_:
I gave up on Chrome long ago... Browsing a site like imgur.com is UNBEARABLE in Chrome, every image has rendering issues and causes it to reload (redraw?) repeatedly. Stock Browser, while outdated and unmaintained, is more stable, faster, and has less rendering issues than Chrome. Sadly, I can't help but feel like Google is screwing over AOSP apps to push their own, and even screwing over their own apps like GMail. If I could find a comparable app store (Amazon tends to be extremely slow on updates), I'd probably drop gapps all together. Have been tempted to just make a list of APK sites/mirrors and use that.
[Nook HD, HD+ Android Development] Tschumi:
I have to agree. the 06-07 is the best lollipop rom so far, even better than cm11

Chrome never worked for me , always slow to load and reloading every time you left a tab. Have you tried lightning browser? It's very light, very fast and material-y.
[Nook HD, HD+ Android Development] twiztid_:
I haven't tried it, but I'll check it out.

There's one thing that keeps me from using a lot of 3rd Party browsers... the lack of Bookmark Sync. I'd love to see one that could use the bookmarks synced to my google account, but I'm not sure if that's possible via permissions or if you'd have to create an entire sync adapter (I don't mean a desktop browser addon). But Chromium's android code is out now, and that has it's own sync, so maybe?
[Nook HD, HD+ Android Development] TBueno:
Yes, "Shutdown" triggers a reboot. Tried in 0530 and 0607-ovation. A workaround I found is to power it off from CWM Recovery's advanced menu.

No such battery issues here though.
[Nook HD, HD+ Android Development] jt61:
brilliant - that works - thx!
[Nook HD, HD+ Android Development] spazimspaz:
I've got the 07jun build running but the screen seems to go crazy when I watch movies... It just blinks on and off I eventually have to hard restart to clear whatever is screwing the screen up. I used vlc beta, vlc, and MX player all the same results. I even changed out the video files... All mp4 though....
[Nook HD, HD+ Android Development] Forsquall:
I didn't have any problems with flickering or Chrome rendering on 0530, but saw the blank-coloured-square issue as soon as I updated to 0607. (Developer Options -> Disable HW Overlay) fixes Chrome on 0607 for me, at a cost of reduced UI smoothness overall.

Sometimes Chrome renders OK with HW Overlay enabled, sometimes not. Does that point to a memory issue?
[Nook HD, HD+ Android Development] techdudepro:
One question: I am kind of new to Xposed, and have some much-needed mods, but when I dirty flash an updated version of a hummingbird build (5.1), will I have to re-install Xposed? Or will it still work? Does it disable itself? Should I uninstall it first? And...how do I disable/uninstall?

Sorry for all of the questions.

And thanks, even if this might be in the wrong forum...
[Nook HD, HD+ Android Development] twiztid_:
Disabling HW Overlays works to solve the issue, but as you mentioned leads to less smooth ui.

After flashing the boot.img on the 06-07 build, I still get flashing but its bearable. I'll get 2-3 flashes on the URL bar, but then its fine for a few seconds, usually enough to finish up my typing or tap an auto complete link.
[Nook HD, HD+ Android Development] spazimspaz:
Thanks for the tip! VLC plays nice and smooth again. I only use it as a video tablet for my kids in the car so I haven't had any issues with chrome.
