I'm just hopping in into this voltage discussion. (For luck my 6810 is working again (tried to mod/replace some libraries in daniels great build and had been down to a soft-brick) - puhhhh that had been a shock for me.)

First of all, I never ever had any SOD on the 6810 (on my i9100 phone I was plagued by it very often). But nevertheless I also played around with the voltages. - Several times over the last month I also mentioned small non-fluid animation glitches, when opening menus or slide through anything. With a slight voltage increase for 200 MHz to 975 mV, this seems to reduce the "micro-hicks" in the very beginning of the animations. - Maybe MY CPU had to less voltage, the phenomenon than not necessary a SOD or other instability is caused by to low voltage but small performance break-ins, is known also from people, who do UV of their S2 phone.

But I would not change the default settings by the kernel for the tabs. But just one question: Are the official voltage tables of the 6810 and 6800 (factory ROM) known?

What about hosting on Google drive!?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, I'm testing a new kernel source now. Will start with the stock values next time.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks, but it is hard to login to Google in our region. The new host should work for most of you guys.
[Galaxy Tab 7.7 Android Development] swissd8:
For some reason i cant read videos anymore with the june 9 kernel, neither with bsplayer nor mxplayer, it just says "opening" forever. Back to june 2 kernel for me, it works fine except the crashes when torrenting without charge as usual.
[Galaxy Tab 7.7 Android Development] GNUDroid:
Just flashed the new kernel 09.06.2013 for 6810. It boots fine, wifi is working good for me!

Did not had too much time to test much, but played around with the interactive an pegasusq govs.

I’m just wondering if the 400 MHz for the GPU is new and if it is working. Started some 3d apps. Mostly played with google earth. Was not able to see any differences concerning the speed.

The CPU frequency is easy to monitor and to adjust. But we do not have any access to monitor GPU response (tried again the app ‘mali status’). – Because I expected some performance improvement with the new GPU-frequency step, but I did not be able to notice any change, I have the simple question, what the up-thresholds for the GPU are and if maybe there some adjustments have to be made.

For the CPU the up thresholds are accessible and I lower them always a little bit from 85% utilization to 75% in order to squeeze out some improvements. Additionally I increase the entropy generator.

Another thing I noticed: When I connect the tab to a charger, the CPU frequency is higher than expected. On the i9100, charging will stick the CPU to lowest frequency (no deep sleep whilst charging), e.g. 200 MHz. Here, on the tab I noticed 500-800 MHz which is quite high…

I know, it is too hard, but sometimes I wished a dev from the mobile corner would show up to support you Daniel. Something like the stweaks would give us the power, to find good internal settings for GPU and CPU adjustments…. A pity that you make to do all this great work all alone. *thumbs up for all you did for us!*

[Galaxy Tab 7.7 Android Development] daniel_hk:
We are now having 3 steps. 160, 267, 400. I think the nextstep algorithm (I modified from siyah) might have problem that cause HD video not start. I'll revert to my 2 step algorithm later. I also got no tools to test it... I can't find "mali status" app you mentioned. Can you give me the link?

When you enter powersave GOV which is the case in lpm, the cpu will lock to 200Mhz. I think i9100 will enter powersave automatically when plugging the usb cable.

I'm quite busy at work lately. Not much time to spend... I'll look into the kernel again after I finish my jobs in hand in a few days. :cyclops:
[Galaxy Tab 7.7 Android Development] strong0:
As I tested, the video player such as mxplayer can work properly with 6/9 kernel, but in my device (6800) the lightness sensor doesn't work. The sensor value in the display setting is 0, so the screen brightness is always the lowest. Please help check if there is something wrong with the kernels. Thanks！
[Galaxy Tab 7.7 Android Development] daniel_hk:
It might be the new GPU dirver's nextstep algorithm cause the video not start. I'll revert to my own algorithm later.

For torrent, I use it as a tool to test the wifi driver. I alway keep it on with a few files downlaoding repeatly. I also asked a few local guys who use torrent frequently to test. We don't have any problem after June 1.

I don't know why you still has crashes. I would really like to copy your situation. Can you PM me your seeds and other details?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, the lightsensor require a new blob which will be included in the next cm10.1 build.

The new sensor driver will have more steps... auto brightness will be smoother ;)
[Galaxy Tab 7.7 Android Development] GNUDroid:
1) Mali-Status (unfortunately not working for us)

Here you go: (running on several i9300 and i9100 kernels)

MaliStatus-0.0.1.apk by bala_gamer

http://d-h.st/423

2) Concerning new kernel-sources from siyah kernel:

At the moment I'm at work, I'll check by time, if in your new kernel the following interface (file) is included. I think the last kernels did not had this folder. - If it is there, we can adjust frequencies and thresholds by simple echo writing. I'm curious if it is now there

"system/xbin/echo "266 350 440 533" > /sys/class/misc/gpu_clock_control/gpu_control"

3) For entropy I used apps. "seeder", "entropy generator" or "pimp my rom" are recommended. Last app also improves the configuration of the govs "interactive" and "ondemand" in a helpful way for our tab. - By time I would have "cat" the actual sysctl parameters.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I didn't use siyah's gpu control. Don't have time to dig into it. Just use its nextstep. I study it briefly. It got better handling in 4412 not 4210. Some of the part for 4210 is missing. The voltage table of 7.7 is also different. Can't just use siyah's driver directly. I have changed the existing driver a lot. At least I know how it works.
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
I've just flashed the new 9-6-13 Kernel, will report later how it goes

I have a different question now, everytime I reboot my phone I get the Android is upgrading text, it only takes 3-5 seconds as it doesn't go through every application as it would after installing a ROM or Kernel, but still, why do I get this "Android is upgrading text" ! Something wrong with my Dalvik Cache? If so how do I fix that?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah. That would be the update of Dalvik cache. probably some of the gapps updates. I think you have already try wiping d-cache.

The only way might be by elimination. Uninstall the suspect apps one by one and reboot see which one cause it.

Good luck!
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Hmmm, I have been using a more updated GAPPS package recently that could be the cause

Alright, but whats the effect this has on my P6800's performance (other than it being very annoying everytime I restart) ?
[Galaxy Tab 7.7 Android Development] johnpat:
9／6kernel update report:

battery performance goes fine

Wi-Fi works

Monitor brightness goes dimmer

Camera broken
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Camera isn't working with the latest Kernel! I know you have only updated the WiFi in the latest Kernel but that's the case, I tried 4 times, just wont work!
[Galaxy Tab 7.7 Android Development] daniel_hk:
No. The latest kernel is from a new source. Some of the drivers require new blobs. Need some time to test.

I'm working on the new PA3.60 HALO with the old kernel. Almost done, will upload in a few minutes.;)
[Galaxy Tab 7.7 Android Development] MRBR7:
Downloading now...

:fingers-crossed:

edit i dont think its finnished uploading..
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Other things wrong with this latest Kernel:

1. Sometimes I loose WiFi signal or it becomes really weak, other times it's gray and not wokring

2. The screen goes really really dark on autobrightness mode

3. Battery performance not as good as before

4. As already mentioned, camera is not working
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks for testing. That was a test kernel. Seems that I need more time to make it work properly.

You may try the new PA3.60 HALO. GPS is fixed. :)
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Thnx, will do :)
[Galaxy Tab 7.7 Android Development] Rokky:
Hi all.

Tried this ROM after stock JB, everything is perfect, except Google Hangouts - it just failed to start with something like "can't enter system because of Google server error. Please retry" (my translation from Russian ;)) Somebody else encountered such errors, or I just happy one?
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
I'm using this ROM and hangouts works fine for me, the way I did was use titanium backup to uninstall google talk app, then install hangouts from the playstore, works like a charm
[Galaxy Tab 7.7 Android Development] Rokky:
do the same without any result.

Also there are continuously repeating message in log: "E/GTalkService( 365): connectionClosed: no XMPPConnection - That's strange!"

And another thing - previously when I was sending mails to my gmail accounts - my tablet received it almost immediately. Now it looks like it check email two or three times per day, no more...
[Galaxy Tab 7.7 Android Development] FernandoMiguel:
i had to manually delete the apk from system, clear app data, and then install from market to get it working

now i need to figure how to get Photo Sphere to work too
[Galaxy Tab 7.7 Android Development] GNUDroid:
tried the pa3.60 build since pure cm10 were not updated for a longer time. for a pa build smooth!

seems that the new kernel inside pa seems to be a nice one.

since i always experienced that cm is faster than pa, i will try to extract that kernel to the last cm rom.... bridging the time daniel may update also the pure cm builds. will report then...

any new project planed under the hood (e.g. kernel related) within the next weeks?

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] FernandoMiguel:
FYI our last test build has a bug in the data transfer stats

https://plus.google.com/109625435637812424164/posts/YTKi7tGCf7C

Once we have a newer build, we will need to delete the netstats files as well so otu start reporting sane data levels again﻿
[Galaxy Tab 7.7 Android Development] arthurson:
hello daniel , i just wanna ask, will you make a mod for official 4.1.2, so we can enjoy the missing bulit-in call recording function ?

i see note 1/2 can do that after adding audio.primary.exynos4.so and audio_policy.exynos4.so on /system/lib/hw, yet it doesn't work on 7.7.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Sorry for late reply... I miss your post...

The blobs in stock 4.1.2 doesn't work on 4.2. Samsung’s phone app use a proprietry way which is not controlled by Contacts.apk. :eek:

No way to do that :(. At least I don't know how... :cyclops:
[Galaxy Tab 7.7 Android Development] GNUDroid:
fast and fluid!! everything working good

still: cm 10.1 is most fluid codebase. thank you so much for the new cm10.1 build!

send from my 6810.
[Galaxy Tab 7.7 Android Development] L_o_k_i:
Hi daniel_hk,

I'm using this ROM since yesterday and so far I'm very impressed. It's much more fluid than ICS! No problem so far except for the auto brightness. It's doesn't seem to work...
[Galaxy Tab 7.7 Android Development] daniel_hk:
If you have a i815, light sensor is not working. Otherwise, you can see the light sensor's output in:

Settings > Display > Brightness > Adjust

The output will be shown in the top left under the title. ;)
[Galaxy Tab 7.7 Android Development] L_o_k_i:
I already saw that (I have a P6810).

The value is changing (0, 7, 70, 700, 7000) but the brightness doesn't seem to change accordingly. By the way there's a problem on the default values:

- 0 lux ---> 0%

- 15 lux ---> 100%

- 150 lux ---> 49%

- 1500 lux ---> 73%

- 15000 lux ---> 100%
[Galaxy Tab 7.7 Android Development] daniel_hk:
I think you came from a dirty flash or accidentally change the value of 15lux. The default values are 0, 24, 49, 73, 100.

As you can see, only a few steps are outpuf from the driver (stock blob). The brightness changes will not be obvious but its there. Try other auto-brightness apps if you want faster reponses.

There is a new driver for light sensor but I don't have time to deal with this minor thing. May be later...
[Galaxy Tab 7.7 Android Development] Esben84:
Just updated from CM 10.1 from 7 April to the latest 23 June version. Even though both are Android 4.2.2, there's a definite improvement in smoothness, both in scrolling the apps drawer, home screens and switching between apps. The browser is also quicker to load pages, and appears to load as fast as my Galaxy S4. Zooming is very glitch free and smooth as an IPad/S4. Thanks for the update Daniel. You've effectively extended the lifespan og the Tab 7.7, so that it's still an excellent device even with more recent devices released.

Haven't yet measured the standby battery life, but I'm hoping it's increased.:)
[Galaxy Tab 7.7 Android Development] daniel_hk:
You may tried wipe cache / dalvik caches and reboot.

If still stuck on boot animation, means there is some incompatible with the cm9 /data. sorry.

Let me think about it again after I take the Tab from my friend. If you don't want to redo the widget, stay at cm9 for the time being....
[Galaxy Tab 7.7 Android Development] carlo67:

I don't want to redo the widget no way lolol it is difficult for me to do all of widgets again because I am disabled guy :cool:

One question. Are you sure that you have over 50 widgets? Or just the shortcut of apps?

If it was just the shortcuts, many launcher like Primo, Nova & Go can backup/restore the desktops...

If possible, please send me a screenshot of your desktops by PM. I wan to make sure how to help you.

I would like to know how to wipe everything [re-format] sd internal in p6800 and how to a flash rom after re-format ?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Are you sure you want to do this? All the data (including Titanium BU, and others) will be gone!

If you are sure, you can do it in recovery. In TWRP, there is a format sd option inside wipe.

Even if you have format the internal sd and do factory reset, only /data partition is touch. The system is still there but it will take longer (up to a few minutes at boot animation) for the first boot.

Goodluck !

Hi Daniel_hk,

thanks for your effort to share with us new rom for our tab, im about to try your latest rom, 17/2/2013, but my concern is, how about 3g video call? is the function available inside your latest rom?

anyway appreciated your work
[Galaxy Tab 7.7 Android Development] daniel_hk:
I don't have the Tab to test it now....

3g video calls work on pa2.55 but haven't tried it on CM10.1.

It tried Skype on CM10.1 briefly, it works too.

Please do make a backup in recovery before flashing. With it, you may restore to your previous state in a few minutes.

Also note that, the content of internal sdcard will be moved to /sdcard/0 in 4.2.x.

Goodluck !
[Galaxy Tab 7.7 Android Development] carlo67:
I was taking about the internal sd.

because my tablet is running very slowly and sometimes force closes

why?
[Galaxy Tab 7.7 Android Development] abima80:
successfully flash new rom, but 3g video call function not available plus bluetooth not working.
[Galaxy Tab 7.7 Android Development] carlo67:
I would like to know Can tab 7.7 [p6800] support 64gb sdcard? When i see the spec on web, it says upto 32gb,
[Galaxy Tab 7.7 Android Development] edan1979:
Usually i will use this file in cwm to wipe all data in my tab if i want to do a full wipe test.

http://d-h.st/LXC

it is singha superwipe cwm files. it will factory reset your device and wipe internal memory as well.
[Galaxy Tab 7.7 Android Development] carlo67:
thanks [ I think about to do it]

does it wipe on ex SD card? I don't want to do that?

I have THE TWRP now

does singha superwipe work with TWRP?
[Galaxy Tab 7.7 Android Development] edan1979:
it only wipe internal data... it work with twrp last time i test.
[Galaxy Tab 7.7 Android Development] Romano2K:
Are you talking about the 24th of June build? I can't find a download link yet. But I'm looking forward to install it after reading your testimonial.

Anyway Daniel, thank your for your work! I second Esben84, thanks to your work and Iocerra's, the Galaxy Tab 7.7 is still the best Android tablet on the market, in my point of view.

And why isn't your ROM an official CyanogenMod ROM? Especially now that CM 10.1 is stable?
[Galaxy Tab 7.7 Android Development] jimmbomb:
Hi everyone, Daniel was kind enough to fix my bricked tab for me and send it back.

Thanks so much, Daniel.

And he put his version of CM10 - 4.2.2 on it, but which is a challenge for me as I am used to Samsung TW.

I am trying to get to know this new Rom , but my question is

How to turn on/off the GPS?

Thanks for a replies!

Go Daniel_hk!
[Galaxy Tab 7.7 Android Development] edan1979:
the same way you turn on GPS... or just scroll down from top to open the shortcut.
[Galaxy Tab 7.7 Android Development] jimmbomb:
There is no short cut in the notification panel? How do you even turn it on?

Thanks Edan
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
I'm currently in my annual summer vacation with wife 'n kids @ the seaside but I couldn't resist the new CM10.1 build so I downloaded the build over the air from my tablet and flashed it and it is working like a charm so far! No hickups or slowdowns or battery drain or SOD, so far Perfect! Add a little wifi-tethering in the mix and there is nothing else I would need :)
[Galaxy Tab 7.7 Android Development] LBN1:
Go to Settings, then Location Access. Toggle on or off.

ALSO, go to Settings, then System, then Quick Settings panel. Click on Tiles and Layout, hit Add, and you can then add a GPS and many other toggles to your Quick Settings.
[Galaxy Tab 7.7 Android Development] edan1979:
oh... the shortcut need to add i think... you can customize it from setting.

and to manually turn on... just go to setting ---> locations
[Galaxy Tab 7.7 Android Development] jimmbomb:
Thanks, guys.. I probably keep the ROM now.. ;)
[Galaxy Tab 7.7 Android Development] Esben84:
Yes, the build is the 24th of June version, which has the filename of 23th. The ROM is hosted by Espen96 in one of the other sub directories.

Battery life for me has been excellent. No standby drain, and finding your tablet still ready for use after days is a real pleasure. I got 3d10h from my last charge, with a lot of web browsing on white pages which consumes a lot of battery. With the new ROM is find web surfing on the tablet a worthwhile alternative to my laptop.
[Galaxy Tab 7.7 Android Development] Romano2K:
I definitely wouldn't have found it without your help! You'd really have to dig to find it by yourself.

http://3djanos.com/daniel_hk/rom/cm10.1/p6810/cm-10.1-20130623-UNOFFICIAL-p6810.zip

It's installed and working like a charm anyway, so thank you.

daniel_hk your ROM is great but your first post is a mess. Don't you think it deserves to be cleaned? :)
[Galaxy Tab 7.7 Android Development] daniel_hk:
If the build date misled you, I can't help...:cyclops:

Like most of other developers who build a few varients, the build dates may not always the same.

I have to test it before release. Sometimes I need to build a few times before it is ready. Only a clean build will change the build date. Even if I got a top end PC. It would take at least an hour to finish. My antique PC would take much longer for a clean build. An incremental build which most of the developer would do is much faster. To test and finish all the three models, it usually reqiures more thatn 24 hours. Upload them to all sites take extra hours. I don't want you guys to waste time on a corrupt downlaod. I need to make sure the ujpload is correct. goo.im sometimes would show different check sum. I have to redo the upload. After that, I update the post and release it.

It is quite annoying and tourblesome to keep 4 relesae areas but there are somewhere in the world can't access goo.im or others. Not everywhere and everyone would have the same resources and opportunities. Never take it for granted. I have no problem to serve the minorities. It just occupy a few hours of my linux PC. ;)
[Galaxy Tab 7.7 Android Development] Thvmh:
How can I go back from this rom to stock JB?
[Galaxy Tab 7.7 Android Development] jimmbomb:
go to here http://www.sammobile.com/firmwares/ and find the JB for your area.

Im in USA and I used the version to Singapore.It works just fine.

then sign up with a username and password, and it will let you download the stock JB firmware.

Then use Odin to flash your tab back to stock.

good luck
