Also running 11/20. But while in settings WIFI scan works after disable/enable, tools like Wifi Analyzer just show an empty screen. It seems it uses other mechanisms to access this data ...
[Nook HD, HD+ Android Development] FoxForceFive:
So the wifi is working as normal, no drops after sleep or reboot?

If so I don't care what the wifi analyser says!
[Nook HD, HD+ Android Development] rholm:
My experience is the same as yours. Random reboots all the time and had to always wipe the caches. I wiped a couple times (takes only a half hour to restore now... maybe I've done it too many times now) and even tried to go back to 10/07 which was very stable for me. I'm now on 11/20 without the trim enabled kernel.

WIFI is good. No problems with it here.

I was using ADW as my launcher, but have gone back to the default as many of my reboots were at the home screen. If all is good for a few day, I might try it again, but with fresh settings. Or, maybe another launcher is better...

My only issue is with the email app. I can't enter my accounts as it keeps crashing.

Cheers,

[Nook HD, HD+ Android Development] TheDannemand:
Thank you! I upgraded from M1 to 11/20 Nightly after reading your post, and I like that new version a lot. I have not seen any WiFi issues (yet); and battery life seems significantly better (for whatever reason, properly working WiFi could be one).

For my part, the WiFi disconnects (or inability to connect after wake-up) was the least of my problems with previous 10.2 versions (including M1). That one was usually easy to fix, either with a tablet reboot or cycling airplane mode.

My biggest gripe was, even when WiFi connected and all looked good, network performance would sometimes become terribly slow. Simple browsing or Tapatalking might not reveal this, but speedtest.net certainly would. That's why it took a few weeks on M1 before I realized something was wrong. Sometimes running a speedtest from another device would fix it, other times a router reset would was required. And one time only a cache and dalvik wipe in Recovery would fix it (even that could have been just a coincidence).

So far I have not seen that that issue on 11/20 Nightly -- or any other issues. I think they nailed that WiFi bug!

As previously mentioned, I triple-wipe cache, dalvik, system and bootdata first. Then flash the ROM, Gapps and Trim kernel2. 99.9% of the time that's probably overkill; but if there is even the slightest chance that it catches a stubborn bit of flash memory, it's worth it.
[Nook HD, HD+ Android Development] FoxForceFive:
I would have thought of you have a faulty emmc chip every time you wipe or write to it you increase the chance of a brick?

I could be wrong, I don't know exactly how emmc wipes data, but if it reallocates or zeroes it over then it would logically increase the risk.

I'm a relative novice with Android though so could be completely wrong.
[Nook HD, HD+ Android Development] TheDannemand:
Maybe, that could be. I don't know if formatting (wiping) actually invokes the trim command. If so, a nandroid restore should be risky as well.

Since I have the Rev 6 firmware, I am hoping it is not affected by the Trim bug. But if I *am* affected, I prefer to have it brick sooner (while I still have warranty) rather than later.

Once I decided to go with the Trim kernel, I decided to stop worrying about it.
[Nook HD, HD+ Android Development] leapinlar:
I don't think normal writing and erasing files triggers the emmc bug. It is the specific way that the TRIM command does its thing that triggers the brick bug. Part of the fix in the TRIM kernel is to make TRIM operate on the chip differently.

Edit: The fixed TRIM kernel just reactivates the command.
[Nook HD, HD+ Android Development] FoxForceFive:
Cool, I don't mind being wrong in my assumptions, especially if it's good news for the majority of people!

Thanks for the clarification.

CM 10.2 nightly

Hello,

I hope I am in the right area.

I have been using the nightly currently the 11/23 ovation for the Nook HD+.

Am I in the right forum?

If so I had some issues with 11/20 the 11/23 seemed to have corrected Email now working, would just flash to home page after trying to setup.

I seem to be able to flash all with the internal SD is this correct or should I use the external SD which does not seem to be working, unless I use on initial boot with SD?

My external SD card is 64 G, at times it does not seem to want to see it? However the built-in file manager now seems to see it fine now on this build.

Anyone using the trim kernel? And what does it do? I have flashed many ROMS but new to the Nook HD+ etc.

Thank you for all that you have done and great work! Just a little confusing and new to CM.

[Nook HD, HD+ Android Development] leapinlar:
See my edit above for clarification on the TRIM kernel fix.
[Nook HD, HD+ Android Development] TheDannemand:
But my understanding is it still includes the workaround (from Nexus 7) which attempts to avoid bricking on select emmc firmware. Please correct me if I am wrong in this assumption.

Oh BTW, I am in complete awe of your efforts here to help Nook owners. I know how much work it can be and how taxing on one's patience!

So thanks to both you and verygreen :)
[Nook HD, HD+ Android Development] leapinlar:
I don't really know the answer to that. Others have stated above that all he did was reactivate the TRIM capability that he had deactivated earlier in the standard CM10.2 kernel.

Edit: see this post:

http://xdaforums.com/showthread.php?p=47676272

Edit 2: If you follow the links in that post referenced above, you will see that verygreen commited the Samsung bug fix to the CM10.2 kernel at the same time he disabled TRIM. So that tells me that by verygreen re-enabling TRIM, the Samsung fix should be there.
[Nook HD, HD+ Android Development] TheDannemand:
Thank you, again. Yes, I saw that discussion, and that was my understanding as well.

I've been following this thread since the beginning, and the CM10.1 before that (and your threads before that). But I only joined the Trim Team after VG posted his second kernel update. I think there is a good chance that (A) the emmc bug is limited to Rev 5 firmware, or (B) the patch actually works (otherwise Nexus 7 2012 would brick as well), or (C) both of the above.
[Nook HD, HD+ Android Development] jamus28:
I've been running with trim enabled on my mag2ga without problems.

Correct me if I'm wrong, but since this whole Trim drama started, only One (1!!) user has a confirmed brick from running lagfix/trim: silkshadow.

I've been following the threads closely and haven't seen someone report a real brick from running trim since the august fix. I feel like the issue has more bark than bite.
[Nook HD, HD+ Android Development] leapinlar:
No, if you follow all of the threads, several have reported trim bricking. In fact, the silkshadow was the first to report it using the TRIM app on CM10.1 in June. But you are right about none reporting since the August fix. So that may mean the fix works. But only on fixed CM10.2 with the TRIM kernel.

I've compiled the Ovation(hd+) cm10.2 kernel with jisoo's Bluetooth tether fix and trim enabled. I hope he doesnt mind me uploading.

Flashing this will work for aosp/cm ROMs and enable trim and Bluetooth internet.

All credit goes to jisoo and verygreen.

[Nook HD, HD+ Android Development] Kubombelar:
hi guys everything i install from apps to games keeps force closing why? did a fresh install, wiped data, cache and internal storage
[Nook HD, HD+ Android Development] nikotime:
Thanks this works great
[Nook HD, HD+ Android Development] jpisini:
Did you install the correct gapps package?
[Nook HD, HD+ Android Development] mg.degroot:
Running de trim kernel together with the nightly for more then a week now, and no problems so far. The chip is the MAG2ga with firmware revision 6. I insalled a new nightly today together with the trim-enabled kernel and still running good.
[Nook HD, HD+ Android Development] Kubombelar:
hi no i did not install gapps......thats related to why i cant run games after installing them?
[Nook HD, HD+ Android Development] leapinlar:
How are you installing apps if you did not install gapps? Sideloading?
[Nook HD, HD+ Android Development] Kubombelar:
maybe i wa abit unclear......i installed the rom and it works fine, however i did not install gapps because i rarely use google apps. Problem is whenever i launch a pre-installed app that comes with the rom eg terminal it force closes OR if copy a game to my internal sd and install it using a file explorer it will force close upon launch despite being installed succesfully
[Nook HD, HD+ Android Development] leapinlar:
Ok, that method of installing apps is called sideloading. And usually that works fine without gapps installed.

But Terminal Emulator FCing and sideloaded apps FCing is not normal. Maybe you should try installing gapps to see if it helps. There may be something in CM10.2 that requires it.
[Nook HD, HD+ Android Development] Kubombelar:
still no luck i dont know why.......although when i install on carbon rom based on CM 10.1.3 (jelly bean 4.2) they are working fine so am not sure what am doing wrong. Am also wiping data, internal storage and cache prior to each install
[Nook HD, HD+ Android Development] leapinlar:
How are you wiping internal storage?

This should not matter, but try wiping /system (as well as factory reseting) before you install CM10.2.
[Nook HD, HD+ Android Development] Crazy Chuckster:
Can we flash this kernel to any version of the cm 10.2 nightly or just the 11/23?

Also do we just flash via boot from ext sd card and install from zip?
[Nook HD, HD+ Android Development] Darrian:
Should be fine on any recent nightly. I'm running it on 11/26 right now, no issues. You flash it in recovery (CWM or TWRP) just like the rom and gapps. If you don't have an internal recovery installed a bootable sdcard recovery will work.
[Nook HD, HD+ Android Development] huntz:
Is this nightly "stable"? I'm concerned about the WiFi problem... Have you tried to play some videos from YouTube?

With the WiFi bug watching 10 minutes of any video streaming is nearly impossible....

Thanks!
[Nook HD, HD+ Android Development] FoxForceFive:
I'm gonna flash a nightly later, however the results on the wifi bug will be negligible cos I pretended my old router was broken to my isp so have a new one that performs much better which possibly would solve the wifi bug anyway.
[Nook HD, HD+ Android Development] Darrian:
Yeah... my router's dead and I am not gonna eat up my mobile data, so short answer: I can't really test that for ya right now, sorry. Can't hurt you much to try yourself, though. If it doesn't work just reflash the rom that works for you and don't reflash this kernel.
[Nook HD, HD+ Android Development] Crazy Chuckster:
Thanks for the tips, I flashed the 11/26 nightly then the new kernel from internal memory and my Bluetooth bug is fixed. We shall see how it performs one it trims itself down the road.
[Nook HD, HD+ Android Development] razholio:
wifi on the 11/26 rom

I've got 11/26 installed along with the trim2 kernel and wifi hasn't dropped out or given poor performance yet, but I still cannot scan reliably. What I mean by this is that while I can scan fine after a reboot, if I sleep the nook and then wake it up at a new location, it will connect to AP's it has saved, but will not (and cannot) scan for new ones. The difference with 11/26 over 10/7 is that I can get scanning back by turning wifi off and then on again.

This is a significant improvement, and enough for me to stay on 11/26, but I'm curious if this issue is unique to my installation or is one others are seeing as well.
[Nook HD, HD+ Android Development] mrhanky89:
Maybe you guys can help. I was using the 10.2 nightlies when my Nook HD+ started shutting off during videos and during audio playback. I changed the rom to Slimbean and the same thing keeps happening. Has this happened to any of you guys?

Here is my original post in the appropriate forum

http://xdaforums.com/showthread.php?t=2545839
[Nook HD, HD+ Android Development] TheDannemand:
I saw this YouTube problem consistently on 11/20, even after I thought all WiFi problems were solved. I then updated to 11/25 the other day, and wasn't able to reproduce the problem when testing the same YouTube videos. Then last night, my wife again found she couldn't play those videos smoothly anymore.

I am now thinking that (A) the problem is partially on the YouTube or ISP side and depends on traffic and time-of-day, or (B) the problem was solved by wiping cache and dalvik (as I did before updating) not by the newer ROM version, and it will come back after awhile.

I still haven't tried going back to an earlier ROM to see if the problem exists (or develops) there too. That would be a hassle, since this is really my wife's tablet, and I would need to restore apps to the same state as on this later ROM, so she can run it for a few days.
[Nook HD, HD+ Android Development] tomlang:
The last few nighties have worked well for me, no problems at all. I came back to cm after spending a month on jisoos carbon rom, just to have usable wifi.

I am downloading the 11/27 nightlie now, and am looking forward to seeing how the new RIL works.
[Nook HD, HD+ Android Development] FoxForceFive:
Forgive my ignorance, what's 'RIL'?
[Nook HD, HD+ Android Development] SteveCoops:
I lose track on what build I'm on (I think it's the latest Slim one as of a couple days ago) and I have the same issue - it remembers my home wifi networks when I'm at work. Manually entering the SSID and password works fine though.
[Nook HD, HD+ Android Development] tomlang:
A Radio Interface Layer (RIL) is a layer in an operating system which provides an interface to the hardware's radio and modem on e.g. a mobile phone.

Hopefully this includes the wifi radio, not just the nonexistent on a nook telephone radio.
[Nook HD, HD+ Android Development] FoxForceFive:
Ahhh. Glad I asked now, was convinced it'd be an acronym for something blindly obvious!

Yeah, hopefully it'll mean stable wifi from here on in.

No doubt we'll have similar trials & tribulations once (if?) we get kitkat!
[Nook HD, HD+ Android Development] tomlang:
Now running the 11/27 build, and it looks good. Connected right up on WiFi, good strong signal, no drops, and shows remembered hotspots as out of range when they are out of range.

BTW, using the trimfix kernel on an HD+ with the problematic emmc.
[Nook HD, HD+ Android Development] Crazy Chuckster:
Well I takebthat back. I flashed the trimfix kernel today and I am still having an issue with Bluetooth. What happens is when I try to use foxfi to Bluetooth tether my Nook to my Motorola Photon, it will pair but the Bluetooth icon will not light up and it says paired but not connected.

The radio button to use the Bluetooth device for internet is always ticked on my Nook and I am assuming that is the Bluetooth bug.

Is there a fix for that?
[Nook HD, HD+ Android Development] Guiyoforward:
Hi everyone, is there a "CM 10.1 to CM 10.2 with bad emmc for dummies thread"? I installed 10.1 following the for dummies thread, but clearly I have a "difficult" unit - MAG2A plus very hard to boot from SD. I would like to give 10.2 a try, with the patched kernel.

Is is safe to use this patch?

Any easy walk through for install? I have CWM up and running so it shouldn't be too hard - is it necessary to update gapps too?

thanks!
[Nook HD, HD+ Android Development] kdejong2012:
What firmware version is your MAG2GA? From my understanding if firmware is v6 then you'll likely not have an issue. I have MAG2GA v6 and I'm running CM10.2 WITHOUT trim kernel patch. Been running it for several days and havent seen a performance drop. If system starts to slow down then I'll install trim kernel.

Read the 5 pages of this thread to get up to speed on trim issues - http://xdaforums.com/showthread.php?t=2528009

Since you already have CWM running, just do clean wipe, install most recent CM10.2 build, and install 4.3 gapps. You have to use 4.3 gapps with CM10.2.
[Nook HD, HD+ Android Development] huntz:
I'm on 11/27 build now, and it looks solid. The WiFi is working as expected.

I'm using also the trimfix kernel.
[Nook HD, HD+ Android Development] marscandybars:

[Nook HD, HD+ Android Development] jamus28:
That's currently a kernel bug with a simple fix that jisoo made.

Edit: Didn't realize you were already referring to the fixed kernel. CM's native tethering works perfectly for me. Don't know about foxfi. If you hit the button to use the other device for internet it will disable or enable it depending, but yes the checkbox itself is bugged a bit. Moreover clicking this box alone won't actually connect internet.

Once you have it paired, you have to hit the name of the device from the tablet's main bluetooth settings page to connect. It should say connected in the notifications and the icon turn blue.

[Nook HD, HD+ Android Development] Guiyoforward:
Thanks everyone - just installed yesterday's nightly and everything seems smooth - smoother than 10.1 in any case. Two questions please:

1-I'm willing to take the risk of gaining performance with trimming. I have the bad chip MAG2A but rev 6, so it does not seem affected. How does one do that? I understand I have to install some specific kernel, where does one get that?

2-Performance is smooth - not just "butter", for instance transitioning between apps, etc. How does CARBON, SLIMBEAN o LIQUID obtain their gains in performance? Anything I can modify on my CM 10.2 to get closer to the performance of those editions? I'd rather stick with modified CM than going to another barely supported ROM.

Thanks!
[Nook HD, HD+ Android Development] beyored:
To be honest carbon is pretty solid.... so is slim other than Bluetooth not working which I rarely use anyway....

[Nook HD, HD+ Android Development] Guiyoforward:

[Nook HD, HD+ Android Development] derschnelle:
1) you go to the first post and take the kernel under the spoiler. Install it via cwm or twrp just like your rom

2) I just moved from slimrom to nightly 29 and am very satisfied with the speed (at the moment even without trim). I think I will try trim when lag starts to annoy me ( I am on Rev. 6 too).
[Nook HD, HD+ Android Development] king200:
I don't agree with your assumption that other roms are barely supported. Enough said.
[Nook HD, HD+ Android Development] deepasadish:

based on this http://wiki.cyanogenmod.org/w/EMMC_Bugs

the Nook HD does NOT have any emmc bug, correct? thanks.

ps. sorry for being paranoid.
[Nook HD, HD+ Android Development] Guiyoforward:
My mistake then - I just assumed that being a CM supported device with nightlies etc. meant more support than other roms that haven't been updated in three months, for instance. Barely supported FOR THE NOOK, not in general. Can you tell me why you consider this wrong? Thanks!
[Nook HD, HD+ Android Development] huntz:
Now I'm with 11/30. The WiFi is going better (anyway it's not good as 10.1.3). Sometimes loading a web page takes minutes instead seconds, but after some minutes the problem disappears (with no user intervention).

Finally CM 10.2 is good enough for daily use. I'm experiencing only some soft reboot scrolling Pinterest or browsing friends to share with on Google Plus (maybe once a day, but is not a very big annoyance...)
[Nook HD, HD+ Android Development] TheDannemand:
I am on 10/30 as well, and agree that 10.2 has gotten really good.

Regarding the YouTube issue, I am now 99% convinced it is either on the YouTube side or with my ISP, or a combination: I tested a number of earlier CM 10.2 and 10.1.3 versions, and all had the same issue: During some times of the day (but not always) HD playback is simply impossible, as the app will re-buffer every 30 seconds or so.

I found there is a conspiracy theory out there that some ISPs (TWC and Verizon in particular) throttle access to all YouTube cache servers, and the suggested fix is to block the device from accessing entire IP address ranges, thus forcing the app to go straight to the source host for the video. See here for a description and fix. However, applying that fix didn't solve it for me (I tried both in Android and on my router). Also, I don't have the problem when playing the same videos in Chrome on a PC.

I never use YouTube myself, but my wife does, and it's her tablet ;)
[Nook HD, HD+ Android Development] marscandybars:
I'm still having issues finding new wifi access points. I practically have to reset the device in order to scan for new APs. Is there a fix for this?
[Nook HD, HD+ Android Development] starbright_:
CM rolled out the 10.2 final.

What is the showstopper for the NOOK HD+ ? Is this just WiFi ? Other things that not work?

Is USB host included now?
