Thanks!:good:

Seems you ran out of Memory. OOM algrithm only work on mutitasking (apps). That explained why it is ok after reboot.

You should remove some unused apps/services which is autostarted. The current pa_gapps is getting bigger and bigger. Disable those you don't needed in Settings > apps. Or you may use the gapps from google(20130301). Which is a bit outdated but Play will update them accordingly.

Someone report that some enhancer apps/mod might help with low free memory.

Good luck!
[Galaxy Tab 7.7 Android Development] FernandoMiguel:
yeah, i'm always on <100MBs of free ram.. but usually free ram is wasted ram, anyways!

i've checked and rechecked and there arent that many things i can strip out. i already remove several apps from gapps after flash, i hibernate several when they arent used, and even mem freeze apps that wake up for no good reason (greenify app)

plus OOM shouldnt affect a service like wifi/network :(
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, OOM doesn't apply to service. That's why you can gain more ram by OOM. I'm also in latest pa_gapps, I manage to get ~200M free ram.

I used to having a few clouds. Now I just keep one or two.

I disabled the following as well:

Box,

Mail, Exchange service

Currents

YouTube (not working on my region)

Good luck!

The best ROM for this device :)

Pretty smooth, good battery life and pure Android xpirience :)
[Galaxy Tab 7.7 Android Development] GNUDroid:
yep, it is! since i had my 6810 i always had been disappointed about the performance and the wasted money for it. daniel gave us a great gift, to reveal 90% of the power our devices have.

i would be curious how other cpu govs or other gpu settings perform, but i don't want to bother daniel to much... i'm so thankful to him!!!!!!!!!!!!!

send from my 6810. community and sharing are freedom are open source.
[Galaxy Tab 7.7 Android Development] GNUDroid:
just read about the new pa builds. which new drivers did you included, daniel? other changes under the hood?

i'm just curious if there are new things and if i should therefore extract the kernel and give it try on the loved cm build.

send from my 6810.
[Galaxy Tab 7.7 Android Development] daniel_hk:
You may find the changes in Change log.

In brief, the light sensor driver can produce one more step and a new power driver (for charging). A new blob (sensors.smdk4210.so in lib/hw) is required for the new driver to work...

Good luck!
[Galaxy Tab 7.7 Android Development] Jaevlar:
Flashed this a couple of days ago. Great work! Come a long way since I last tried out cm10 for the 6810. :)

Not sure if anyone has mentioned this in the thread (if so, sorry) but here goes.

Anyone noticing som clipping when playing sounds? For example, watching a movie on youtube, playing music in spotify etc. The sound dies instantly when there's silent parts and then comes back "hard" when there's sound again. Same problem if using speakers or headphones. Hope i made myself understandable ;)
[Galaxy Tab 7.7 Android Development] Edwrib:
Just saw a yesterday build of kernel inside you folder, anything new? :)
[Galaxy Tab 7.7 Android Development] daniel_hk:
Nope. I haven't release any new kernel lately. I did release the PA3.60 recently. You may find the change log in my PA3 thead.

Testing some drivers now. It takes time to test them all and select.:cyclops: Might put into a new cm10.1 build in a few days. ;)

I have the same bug with my tablet.
[Galaxy Tab 7.7 Android Development] sas_sas:
Hi chef,

I wonder if the time came to use CM 10.1.2 which said to have security update patch and masterkey features?
[Galaxy Tab 7.7 Android Development] grazy:
Thanks Chef, the security hole is patched finally :)

Ps: The screen appeared to be more blue than usual, and also I'm having difficulties to play video clips on Instagram.... no issue once reverted back to the latest PA3.65, kernel issue?! thx.
[Galaxy Tab 7.7 Android Development] scubajeff:
neither YouTube nor local video played. lock screen always in landscape mode.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks for the report!

Yeah, must be the kernel. Didn't test long enough before building the new PAC... :o

Can flash kernel-s on 0602 for the time being, only auto-brightness not working... Or try the new PAC first...

i815 looping boot newest cm release from goo

The newest cm from goo causes a boot loop on my i815. Did a second download with same result. Cleared user settings cache and palvic first and even tried pa full gapps and the newest reg gapps - still boot loop. Reloaded 6-24 still works rock solid with the pagapps.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I can only test it in p6800. May be its a kernel thing. Would you like to try flashing 0602 kernel -s on top? Tell me the result. Thanks! ;)
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
1. full wipe

2. install cm 07-14

3. install kernel 06-02

4. reboot

boot loop

unsure which kernels come with which cm release so

1. install cm 06-24

2. install kernel 06-02

3.reboot

works fine

1. installed kernel 06-09

2. reboot

works fine

1. installed cm 07-14

2. installed kernel 06-09

3. reboot

boot loop
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks for your help!

Someone report the similar thing for the latest PAC which is mainly CM base. Must be something wrong with the latest CM updates to i815...:eek:

I'll take a look after return home but I might need you to test it for me if I come up with something... ;)
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:

[Galaxy Tab 7.7 Android Development] daniel_hk:
I have a test build for i815 cm-10.1-20130718-UNOFFICIAL-i815a.zip, please test if it boot?
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
test build also boot loop

after full wipe I uploaded your test build and the tablet still went into boot loop.

by boot loop i mean it goes into the first screen past the cyanogen circle but then reboots. - just to be clear

here all day
[Galaxy Tab 7.7 Android Development] daniel_hk:
Can you dump the logcat and PM to me?

You can connect the tab and issue "adb logcat > <filename>" before boot up. The file will be created after it reboot.

Thanks! ;)
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
hmm

doing build on a new c compiler - will do when finished
[Galaxy Tab 7.7 Android Development] CPmillenia94:
How difficult would it be to add the kernel capability to adjust the color multipliers for the display? The same way the galaxy nexus trinity kernel or Franco kernel can?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Have no idea yet. Might take a look later ;)
[Galaxy Tab 7.7 Android Development] CPmillenia94:

Thank you so much that would be an incredibly valuable feature!
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
adb

OK so i learned a bit about adb and got it installed.

Learned how to put tablet into developer mode and set it to usb debugging.

Rran 1 log for june's cm10 from switch on till boot complete and one for the july cm 10 through 2 boot loops. PM to you now

HOPE I got it correct

PM wil only allow 15000 characers at one time. both logs show to be much more. May I use an alternate email for them?
[Galaxy Tab 7.7 Android Development] scubajeff:
in google map, current heading pointing to opposite direction. some sensor data readings must go wrong.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I just checked. My p6800 is OK. If you are not from a very old version, you may try flashing the old kernel-s on 0602.

You didn't mention which model you have. I can't do anything..:cyclops:
[Galaxy Tab 7.7 Android Development] scubajeff:
p6800. i have flashed the latest built dated 16/7, and someone mentioned that flashing kernel603 on top of it will result in boot loop, so.....
[Galaxy Tab 7.7 Android Development] daniel_hk:
You got it wrong. Those are i815. :D

BTW, you may install a compass app to verify the direction.

Good luck!

PS. Just found out that CM changed some blobs on July 13. I think that cause i815 not boot. Rebuilding a test now.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Here is another test build cm-10.1-20130720-UNOFFICIAL-i815.zip.

Please test if it work?

Thanks!
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:

[Galaxy Tab 7.7 Android Development] FernandoMiguel:
uhh new wifi driver!

time to see if that fixes one of my two issues :D
[Galaxy Tab 7.7 Android Development] CPmillenia94:
So I installed the latest build for p6800 and the green tint on the screen is really apparent, more so than on stock for some reason. I really think the ability to adjust the display would add so much to this ROM and the tablet overall! Have you learned anything regarding that capability yet?

P.S. thanks for all the awesome work youve done this rom is otherwise incredible!
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
still boot loop

downloaded and installed without clean wipe - boot loop will do again with log to your gmail
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
boot loop gone

the newestcm for the i815 you sent me seems to be working - well no bootloop for sure.

Thanks again - I ran a log while booting but did not think you would care to have it since the system now works - As I said before if you need any thing I can help with please don t hesitate to ask.:laugh:
[Galaxy Tab 7.7 Android Development] daniel_hk:
Good to know that! :D So the 'b' version fix it, right?

A log will be great, I can save it for future comparison.
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
yes B worked - log on way
[Galaxy Tab 7.7 Android Development] scubajeff:
very strange thing happened. incoming call won't ring at all, and leaves no missing call record. the calling party said he heard ringing on the other side. i have to rolled back to 6/23 build and 603 kernel-s
[Galaxy Tab 7.7 Android Development] daniel_hk:
If you are in the latest 0716 build, telephony may have trouble. One report that keys at call not working. Thus can't hang up. I've been digging for two days and found an incompatible issue in the Samsung blobs with the new Telephony. Just managed to add a fix in PA3. It's getting harder and harder to port our tab to new codes now... :eek:

May release a patch for p6800 cm10.1 later.
[Galaxy Tab 7.7 Android Development] scubajeff:
while go back to 6/23 build, i recheck google map's heading direction, it's correct. so there must be sth. wrong with 7/16 build.
[Galaxy Tab 7.7 Android Development] FernandoMiguel:
so, what's up with 0716 build:

screen is tinted. mDNle scenario is broken.... picking options favors tinted or warm options.

outdoor and inverted modes broken.

both stock camera and 4.3 camera are non funcional. youtube wont load any video. cleared data on both!

kernel no longer lets set min or max freq.

it's much smoother than previous build, uses less ram, with the same gapps (300MBs free vs 100MBs)

wifi non-startup bug is still present, and it feels like wifi uses much more power now.
[Galaxy Tab 7.7 Android Development] scubajeff:
can't download the patch file
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have tested many times. It's there!? Just a simple attachment in xda. Already have a number of downloads now. Don't know why you can't download it. :confused:

You have to be more specific. Did you usd a PC or the tab to download?

Anyway, I uploaded to one more place. http://3djanos.com/daniel_hk/index.php?dir=rom/patch

It's quite annoying, discouraging and time wasting with these kind of things... :(

Good luck!
[Galaxy Tab 7.7 Android Development] scubajeff:
i'm using tab. the link you posted just now works. thank you and sorry for the disturbance

[Galaxy Tab 7.7 Android Development] GNUDroid:
hi daniel. had been abroad for a week, therefore just had today the first chance to try the new cm build. it works great! just somehow the colors intensities are very weak and additionally it seems that OC support had been romoved. why? 1600 MHz worked great. it is possible reimplement this?

send from my 6810. supported by 9100 and my linux desktops. brain in the head and GNU in the heart. community and sharing are freedom are open source.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I try to include a new kernel in it but seems I haven't had enough time to test. You may flash kernel-s on 0602 and everything will be back.

Good luck!
[Galaxy Tab 7.7 Android Development] GNUDroid:
thank you very much for the quick reply. sorry about the color issue, it has just been the device setting which changed it default color profile whilst flashing... strange...

so if nothing else changed, i will revert to the kernel mentioned by you in order to be able to overclock that little bit.

best wishes to you!
[Galaxy Tab 7.7 Android Development] will2live:
Silly question I'm sure but having no luck finding the answer. Dont ask but i was doing some stuff around the house and come to find sitting I still have an LTE version of the i815 which i thought I sold. Anywhoo i'm curious being its the LTE version and not Wifi only will data still function correctly if I flash a JB rom to it seeign as VZW/Samsung are slacking on getting JB pushed to this device. Its not a big deal either way i'd just like to know because if data will work I may just flash one of the JB roms, but if not i may just leave it on ICS so data functions when I throw my spare SIM card in it as i still have 2 unlimited data accounts threw VZW. thanks in advance for the input, Peace.
[Galaxy Tab 7.7 Android Development] teiglin:
There is no official JB for i815, but daniel_hk makes builds of cm10.1, PA, and PAC ROMs for all three 7.7 variants (including i815), which are JB 4.2.2. I know that i815's IR blaster will not work with these ROMs, but I think everything else does (usually). Someone with i815 can probably give you more specifics on what bugs there are. :)
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
my sch i815

Using his most rescent cm for this model and everything is great - def no ir blaster but thats not implemented in cm.

You want the July 20 package - makes this tab run better then my nexus7 and Asus transformer. 4g DATA IS GOOD TO GO
[Galaxy Tab 7.7 Android Development] will2live:
Sweet..... Thanks for the input/info folks. Greatly appreciated
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
This maybe a silly question but I have to ask:

I recently bought my wife a galaxy note N7000 and I installed a custom ROM on her mobile that has the multiwindow feature from the galaxy note II working (this is where you can split the window and run more than 1 app at the same time)

The question is, is there a way we can port such a rom to our beloved 7.7? Or maybe not the ROM port such features like the multiwindow, or the smartstay or other features that are in the Note/NoteII/Galaxy S4 ?
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have a few request before. Seems it only works with Samsung's framework. You may have a cooked rom from a stock rom.

I don't have a device that can run multi-window so I can't try. Let someone has both devices to try. There is a post in GT-Plus thread about this. Anyone interested may take a look.
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Yes, that's right it's a cooked ROM based on stock 4.1.2

So there's no way to port this stock 4.1.2 framework to our 7.7

Thanks Daniel :)

Have you tried the official samsung release of 4.1.2 DXMD3 on your 6800? I saw they started the release in may.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I only tired it briefly for testig some drivers. The internal sd content need to move back from the '0' folder. It would be quite annoying when switching back and forth. The look is similar to ICS with no apearing difference but there is thing like multi-window might worth trying.

Good luck!

pls note that, it was with the same kernel optimization. Governor pegasusq and i/o schedular sio..

fstrim and the app lagfix

Hi Daniel,

I'm still enjoying your last cm10.1 build, now with the old overclock-able kernel.

Since my tab ist almost 2 years in use and I made good experiences with the lagfree app, I have the request if you could implement the "fstrim" binary in your next rom?

"fstrim" and "lagfree":

fstrim is well knwon from linux and enables manual trimming of ssds. It became more and more clear, that many phones and tablets benefit in memory, if sometimes the disk is trimmed. On my i9100 phone (not officially supported by the app "lagfix" (which just runs the "fstrim" command with the right parameters on the internal disk) I have very good experiences. Everyone could decide if it also works savely for the 6800 or the 6810 tabs.

The problem is, that androids 4.2 kernels have no automatic trim support for flash disks (on linux desktop, the kernel does this automatic since approx 1 year). And a normal format, will not bring the internal controller to make a proper release of all free memory blocks.

If you could implement the fstrim command some when a new build is planned, I will report if my data survived it. ...

best wishes!
[Galaxy Tab 7.7 Android Development] daniel_hk:
I had tried fstrim briefly before. I also test in my TWRP build which has a different kernel. Seems it is not working on the filesystem of JB. Didn't dig too deep. I thought someone would upgrad it for JB.

I've been working on cm10.2 for 2 days. With the old kernel and blobs, it is much harder than the Nexus devices. I can build it out but it would start bootloop when the lockscreen appear. Studying the AOSP and PA3 source now...:cyclops:

I took a coding job earlier today. It will occupy most of my time for a few months but I'll continue once a while. ;)
[Galaxy Tab 7.7 Android Development] TheDoolster:
Daniel, I just want to say how thankful I am for your hard work developing for the Samsung Tab 7.7. :)

You have contributed so much to the development on this device.

Sadly I am leaving this tablet for the new Nexus 7. I am going to miss the great (but small) community for this tablet, and the AMOLED screen technology.

Good luck with your development,

The_doolster
[Galaxy Tab 7.7 Android Development] GNUDroid:
take your time! we are really comfortable with your rom at the moment!

because you mentiomed fstrim would not be on jb: at the moment i am on slimrom sabermod (4.2.2, almost nightly) with kangbang kernel (the stock one from fusionjacks slimbean is also great) on my i9100. there fstrim works fine.

who is brave enough could try my build.prop additions + latest crossbreeder on their tabs. it gives some nice boost.

do not ask me about the sense (e.g.if all parameters are still available in jelly bean) but for me the build.prop additions work great.
