Hi mate,

How are you freezing the phone apk?

I don't see anything with the word 'phone' displayed in the list of apps in Titanium backup (I have messages, mobile data and mobile network configuration....)

Cheers

Macca
[Nook HD, HD+ Android Development] jisoo:
You can always just delete the phone.apk file from /system/app, either through recovery (if you have TWRP), or even from the nightly zip itself, I think.
[Nook HD, HD+ Android Development] Reed-Sternberg:
Good to see you back.

I'd say by popular demand, a new trim kernel. And probably not-so-popular: any chance for a kernel with the possibility of overclocking CPU/GPU?

thanks man

Download speed

I've had a search but no luck so far... My wifi network download speed is rubbish (trying to download today's, 10.2 nightly) at around 1 to 6 KB/s and cant find a fix :( Any help would be appreciated :)
[Nook HD, HD+ Android Development] Sherip:
Funny, just in the last couple days I burned and set up a new 16gb sdcard from scratch to overcome the lag that had developed over time with my 8gb card. Then in a frustrating exercise I tried to fix the old card and ended up with a card that wouldn't start. Not sure if I ever previously tried restoring to sdcard in its cwm, advanced recovery of data-only failed (gave errors). Complete recovery appeared to be successful, but when restarted it seemed dead (no logo, animation or other sign of life). The new card is working fine (Google auto installed apps, after which I selectively reinstalled other apps and data with Titanium, and just now updated with the 1030 zip). I did notice that my About Tablet info shows serial number as "unknown", and couldn't recall -- is that appropriate for the sdcard install?

[Nook HD, HD+ Android Development] razholio:
those of us on the trim kernel are seeing very poor wifi behavior (dropping out, poor speeds, failure to scan, etc) since the 10/7 build (though that one is fine). I'm guessing the trim kernel needs an update. I don't suppose you'd have time for that? I'm pretty happy with 10/7 right now, but would rather not get too far behind...

---------- Post added at 11:22 AM ---------- Previous post was at 11:19 AM ----------

I froze 'mobile data' with TiB and that allowed me to boot all the way up (no more phone.apk crashing), but wifi is rubbish with at least the 10/29 build. You guys seeing good wifi performance with the trim kernel and recent builds?
[Nook HD, HD+ Android Development] :
I don't know if the trim kernel is introducing other issues but wifi problems are there without the trim kernel.
[Nook HD, HD+ Android Development] razholio:
Ah, thanks for the clarity. I was thinking it was all of us on trim, then some trimmers said they were OK and I figured it might just be lucky me. There must be something else some of us have in common causing bad wifi.
[Nook HD, HD+ Android Development] tomlang:
r

I don't dare use the trim kernel since my HD+ has the suscetable emmc and my previous HD+ died a horrible emmc death while using killersloth's last carbon ROM build.

That said, my WiFi performance is terrible. I am trying jsoo's carbon ROM, and WiFi works very well but it is terribly laggy.

Except for killing my previous HD+, killerslot's carbon was the best I have ever run on this device.

[Nook HD, HD+ Android Development] Sherip:
Thanks. BTW setting up my old 8gb card and reinstalling apps worked fine. So the card is OK. Only restoring from my cwm backup is problematic. Is it a known issue you can't restore to sdcard from a cwm backup of same? The restore successfully completed, just wouldn't boot.

So uh any issues with the "nook hd" not + version and the trim kernel? Sorry im new to the nook development :)
[Nook HD, HD+ Android Development] Darrian:
I can't run M1 and the new trim kernel, it crashes the phone service again. Otherwise I'm not having any major issues with the M1 build yet.
[Nook HD, HD+ Android Development] Reed-Sternberg:
freeze/uninstall the phone app. I used 'app master' from play store. there are a bunch of them you can use.
[Nook HD, HD+ Android Development] HiddenG:
No, hummingbird/Nook HD is not affected by the TRIM kernel. It's only ovation/Nook HD+ which has these issues. Which is good and bad news all in one I guess. ;)

UPDATE: For those quoting. I believe this is true, as the Nook HD does not use the same Samsung chip. Of course, I could be wrong, but my source: http://wiki.cyanogenmod.org/w/EMMC_Bugs :)
[Nook HD, HD+ Android Development] fma965:
Ok thanks for the simple and quick response, i don't usually get people to answer for me... usually i find it out my self by researching but i didn't have time.
[Nook HD, HD+ Android Development] Darrian:
I may try that if my Nook starts slowing down, but for now it seems to be pretty snappy. It would be nice if trim was built into the rom with an option to enable it with a warning in the performance settings, though.
[Nook HD, HD+ Android Development] verygreen:
I would not be so sure.

Trim problem is a function of the emmc chip used. If you have an affected chip on Nook HD, then it still might be susceptible to problems for all we know.
[Nook HD, HD+ Android Development] stegg:
For those who have WiFi and/or phone issue, I suggest to flash carbon ROM by jisoo, the maintainer did make a great work of optimisation for our HD/HD+: phone app is disabled and WiFi commits are reverted to a stable version
[Nook HD, HD+ Android Development] fma965:
how can i check what emmc chip i have? I tried googling it but didn't find any information. Thanks, And Great work on all your development on the nook hd and nook hd +, [MENTION=3654172]verygreen[/MENTION].
[Nook HD, HD+ Android Development] HiddenG:
Thank you very much for your response verygreen, and like everyone else I appreciate your work on these tablets, sincerely. According to CyanogenMod Wiki, EMMC Bugs, hummingbird/Nook HD is not affected. Perhaps it uses a different chip for storage? Or no Nook HD uses the MAG2GA MMC? As opposed to the Nook HD+.

Of course, I could be wrong, as I'm sure you're aware of these factors. Again, I appreciate your response. :)

You can check your EMMC details by following this guide, put out by CyanogenMod (thanks to them): http://wiki.cyanogenmod.org/w/EMMC_Bugs#How_do_I_check_my_device.27s_eMMC_details.3F

[Nook HD, HD+ Android Development] marscandybars:
Is there a link for the newest kernel (emmc) ?
[Nook HD, HD+ Android Development] razholio:
You can also search the app store for 'brick bug emmc' if that's easier. The 16GB HD doesn't have one of the known chips, but until proven otherwise, any Samsung emmc is suspect.
[Nook HD, HD+ Android Development] fma965:
i have a nook hd 8gb. thanks for the app link.
[Nook HD, HD+ Android Development] rhyang:
Look at the first post in the thread, verygreen has updated it with links.

I was running emmc nightly 9/24 and just upgraded to m1 yesterday, plus the new trim kernel. Works great, no WiFi issues, Even kindle works. Good stuff. My emmc is a 16gb sandisk.
[Nook HD, HD+ Android Development] rpop:
woohoo

After being unable to stand the lag anymore, I decided to go ahead and brick mine and do a warranty swap (I have MAG2GA and 0x000015 manfid).

I went ahead and installed cm-10.2-20130820-UNOFFICIAL-ovation-emmc-fstrim-take2.zip I found earlier in this thread, ran TRIM, and, to my surprise, didn't brick it. Just to be sure, I flashed kernel-fstrim-ovation.zip, ran TRIM again, still no brick. Updated now to the latest trimfix-kernel-ovation-2.zip, still no luck bricking it (there's words I never thought I'd type :p).

I see some other people have been having good experiences with this kernel; count me as another vote of confidence. I hope it sticks, but if it bricks down the road I'll be sure to update here.

I was suprised at how quickly TRIM runs; some of the comments earlier in this thread had me thinking I'd be waiting a while for it to complete, but it takes 2-3 seconds tops. I almost thought it didn't run properly, but sure enough the micro-benchmark in Androbench confirms my sequential write speed jumped from 0.37 MB/s prior to TRIM to 14.92 MB/s post-TRIM, and tablet is definitely speedy again. So happy not to have a paperweight anymore :D. Thank you verygreen! :good:
[Nook HD, HD+ Android Development] dmullens:
I was well am tired of the lag. Just flashed the trim kernel. Do I just wait for trim to run automatically or am I supposed to do it manually? When does trim usually run?

If I'm to run it manually what's the best way? Thanks all.
[Nook HD, HD+ Android Development] ArcSmurf:
Have been using lagfix from the play store to run manually when tablet seems sluggish, so far been working well. Running the cm10.2 M1 release and new vg kernel.
[Nook HD, HD+ Android Development] rpop:
I used LagFix Free the first time, after that I just typed the commands it runs into Terminal so I could uninstall it since I wasn't fond of the ads:

fstrim -v /system

fstrim -v /data

fstrim -v /cache

su beforehand since you need to be root first, of course.
[Nook HD, HD+ Android Development] dmullens:
Thanks! What an improvement. I decided to try the kernel because the thing was so slow. Figured if it got bricked I'd try returning it. If this is a known issue and the lag happens on stock as well, why no recall?
[Nook HD, HD+ Android Development] gunz.jones:
Used the latest nightly and the new kernel with trim. Works like a charm. It wasn't too bad for use before, but that little bit helped plenty enough. Thanks, VG.
[Nook HD, HD+ Android Development] joe_blow_xbox:
Thanks. Do you need to enter this after each reboot or only once?
[Nook HD, HD+ Android Development] verygreen:
in fact you don't need any app for that.

Just run "vdc fstrim dotrim" and it'd run fstrim on all mounted filesystems (or will try to, anyway).

[MENTION=3654172]verygreen[/MENTION]:

From my point of view the kindle issue is solved (marked as problem in initial post). Maybe by the change in build.prop or by update of the kindle app.

I am not sure, why all wifi analyzers I have tested are not able to scan the network. I setup a CM10.2 10.26 after full wipe and still have this issue. Are the apps not compatible with 4.3/10.2 or is this a Nook specific problem.
[Nook HD, HD+ Android Development] rhyang:
WiFi Analyzer works fine on M1 for me. The one nightly I tried was 9/24 which was also fine. In between I'd read about WiFi problems but did not experience them.

WiFi scanning did not work on the previous (earlier in September) SD card builds so I was glad to see it finally working. Maybe a fresh install will help you.

CM10.1 updated to CM10.2

Today I have updated my Nook HD+ with the bugged chip MAG2GA (HD+ 16GB) to CM10.2.

trimfix-kernel-ovation-2.zip - md5: becad8723b2a7bb5de5504a4c5924143

After the update and a reboot, I have run on Terminal (after a "su -"):

fstrim -v /system
fstrim -v /data
fstrim -v /cache

and also

vdc fstrim dotrim

with no problems to report. :good:

The lag is gone and the speed of the device is really nice :victory:

Yeah I too am running trim on 10.2 with the flawed emmc chip. If it bricks I will live with it.

[Nook HD, HD+ Android Development] huntz:
Try to change channel on your router, maybe you have some nearby interferences...
[Nook HD, HD+ Android Development] rholm:
I get command not found for vdc and ftrim. I'm pretty sure I installed the trim kernel. How can i verify? What should the kernel version show?

Other than that, everything is running great on M1.

[Nook HD, HD+ Android Development] laofan:
Have you tried to put in Terminal the "su" command first?

you might try this:

$ su

# vdc fstrim dotrim

（ you don't have to type $ or # in Terminal)

good luck

Not likely. Have no wifi issues on the 10/7 rom and the problems are not limited to AP connectivity.

you missed an "s" in fstrim

[Nook HD, HD+ Android Development] starbright_:
Two questions:

As we just talk about su in terminal: After become root by "su", I am not able to call history by "arrow up/down" or autocomplete with "tab". It is working, when I am a normal user. What might be the reason and how to change this?

This reports about trim: Does it mean, that something has been fixed (in kernel ?) so that it works also with this faulty(?) chips - which let the devices bricks at the beginning?

What is a good indication that running trim might make sense and how to measure a hopefully positive effect?
[Nook HD, HD+ Android Development] Phenomeno:
I'm in possession of NOOK HD+ ( 16GB ) with infamous Samsung eMMC chip MAG2GA . Last night decide to give a shot and try last Trim kernel from [MENTION=3654172]verygreen[/MENTION]. My Nook is still alive with no problems to report. I hope to see some overclocking options and more governors to play with...

Relating to this thread: http://xdaforums.com/showthread.php?t=1592535 OMAP 4470 is able to run with 1.74Mhz clock speed without issues.

[MENTION=3654172]verygreen[/MENTION] could you compile a kernel with GPU overclock from this thread and TRIM enable?

[Nook HD, HD+ Android Development] Reed-Sternberg:
In case an overclock, if we don't do extensive gaming/benchmarking, it's safe to assume that the battery/chip life won't be drastically impacted. using the activity monitor, I noticed that the moments of UI stuttering are the ones that CPU maxes out. an overclock could presumably benefit those.

[Nook HD, HD+ Android Development] huntz:
I understand, but often WiFi networks are on auto channel mode, so now, maybe, you get some new interferences from your neighbours...

Changing your router settings it's an easy step trying to debug your problem... :)
[Nook HD, HD+ Android Development] razholio:
Sure, I get that. However, the 'problems' are seen on multiple AP's, and are not isolated to AP connectivity (failure to scan). Reverting back to 10/7 makes the problems go away. This is not interference...
[Nook HD, HD+ Android Development] huntz:
From my understanding of the trim problem, if you get a good run, the kernel patch is working correctly and the ROM is safe.

If there is some problems, even only one fstrim run will be fatal...
[Nook HD, HD+ Android Development] silkshadow:
That was not my experience at all. Ran lagfix many times then all of a sudden ran it once manually and bricked Nook.
[Nook HD, HD+ Android Development] swaaye:
I've returned to 10.1.3. The WiFi is really unreliable with 10.2 at the moment and honestly I think 10.1.3 feels faster anyway....
[Nook HD, HD+ Android Development] huntz:
Arg! :)

Thank you for the clarification... Now I don't feel so safe anymore... :confused:

Anyway, after the release of the fixed kernel, I haven't read anyone complaining for a brick...
[Nook HD, HD+ Android Development] Sherip:
Still wish we could turn off the automatic execution and do it only manually. At least if it bricked we'd be certain of the cause. I'm still running from SD which finally got so bad I remade my card. Not as convenient as emmc/trim would be but fortunately mine is peppy again.

I flashed both the milestone release of 10.2 and the trim kernel to my HD+ with a faulty chip. Now I'm having BT connectivity issues. I cannot connect to my headphones, nor my AirTurn device.

[Nook HD, HD+ Android Development] king200:
Is there a script file that can run with something like ScriptManager that can be run but only when I want to? I think most of it is already in your post.
[Nook HD, HD+ Android Development] TeutonJon78:
Why no recall? TRIM wasn't added to Android until 4.3, and the device officially only has 4.0.3. So, in a stock device, there is no way to hit the problem. If a running a non-stock firmware, it's not something that B&N need to repair.

Edit: Typos

Also, with the Nook tablets being discontinued, B&N doesn't really care for them.
[Nook HD, HD+ Android Development] Darrian:
Ugh, that's a good point. I guess we can absolutely rule out ever getting an official firmware update that brings it up to android 4.3 or 4.4, even though 4.4 might bring better performance than stock is capable of. Thankfully we have Cyanogenmod!
[Nook HD, HD+ Android Development] TeutonJon78:
Well, there is also the supposed problem that the Galaxy Nexus is having -- lack of drivers.

4.4 changes some of the driver interface again, and we may not get them for our device, especially with TI discontinuing OMAP. Now, it seems that there are some drivers that will work.

Hopefully we can still get 4.4 for our device.
[Nook HD, HD+ Android Development] bsharitt:
Well the unofficial efforts to get 4.4 on the Galaxy Nexus seem to be moving full speed ahead, so hopefully there won't be a problem for this device.

On another note, I've been reading the last few pages of this thread about the lag issues that I'm getting really bad and will hopefully fix today. And to think I replaced my old Nexus 7 with the Nook HD+ because it had the same issue. I guess I'll try to fix the issue this time.
[Nook HD, HD+ Android Development] razholio:
I just flashed 10/7 and first trim kernel and that worked fine. Restore from backup is also nice. ;)
[Nook HD, HD+ Android Development] bsharitt:
Trim kernel flashed to M1. So far so good and the lag is gone.
[Nook HD, HD+ Android Development] rpop:
Is there any TRIM fix kernel for 10.1.3? The 10.2 milestone has too many issues for my taste; almost every game I try to run crashes.
[Nook HD, HD+ Android Development] bsharitt:
Unfortunately I seem to have lost about 6gb of storage space.
[Nook HD, HD+ Android Development] rpop:
I've had this happen numerous times as well after switching/flashing to and from various ROMs, as the wipe data & system partition options don't really seem to do that :confused:. Open Terminal and run du, which will list all the files in your filesystem with their size preceding them. Scroll up and down until you find whatever seems to be taking up the most space (for me it was traces of old apps that were not installed, yet were still present on the device), take note of where they're located, and delete them using the file manager (or the terminal itself).

Edit: On mine, it looks like most of the leftover crap was in /storage/emulated/legacy/Android/data. I've never managed to fully remove everything, I'm still missing like 600 MB space, but at least it's more manageable. I'm not sure how to fully reformat the device at this point, I may have to just rm -rf / before the next time I flash CM.
[Nook HD, HD+ Android Development] leapinlar:
Rpop,

Just do a format 'data and datamedia' in mounts and storage. That gets rid of everything, including your media files.
[Nook HD, HD+ Android Development] starfighter1948:
Wifi Analyzer doesn't show signal with the M1 + trim kernal - is this just me? This problem seemed have been cured with one of the nightlies but it looks like it is back.
[Nook HD, HD+ Android Development] huntz:
No, because 10.1.3 is based on Android 4.2.x and the TRIM feature is only for Android 4.3 (CM 10.2).
