COlors going crazy info and other gpu issues

If your display freezes and you have to hold the power button down to force a reboot then your gpu is locked up - why - because the gates inside the chip failed to reset themselves when an invalid path was in-acted due to a bad current through the chip. Usually means your freq and voltage levels are not working together well.

If your image is sharp but all of a sudden the colors are off - blue becomes pink - then this can be caused by to low a gpu freq or a mismatched freq and volt age setting.

I have best results of no lock ups and no color distorts with

min gpu freq = 160

gpu min freq volt = 950

max gpu freq = 400

gpu max freq volt = 1150

Since the GPU chips were produced by two diff manufacturers for the ones in our 7.7 tablets then you will need to figure what works best for you.

Just Know that volts and freq work together - Without enough volts the freq wont be steady.

This all sounds good but if you know diff then lets here it.

Thanks John. I will give it a try, as i would like to run Daniels newer builds without the lockups.

Anybody knows how to make screenshot with this rom??
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
It should be an option as a ring target. Then you just use it. I am sure there are other ways but i don't have the omni rom loaded right now
[Galaxy Tab 7.7 Android Development] kriegschluesser:
Where to find these gpu setting? Setting>performance or else? because i dont find any gpu there. only cpu. i installed Extweaks and its says kernel doesnt support... etc...
[Galaxy Tab 7.7 Android Development] raducux:
Try holding volume down plus power button for one second
[Galaxy Tab 7.7 Android Development] kriegschluesser:
i've tried. it says recorded screen. open the gallery, and theres nothing except grayscreen with triangle icon as is if its a video file...
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
It looks like with omni that performance settings are not available for change.

You will have to build the rom with your own settings or wait until a new release or switch to CM or slimkat.
[Galaxy Tab 7.7 Android Development] daniel_hk:
If you spent a few seconds to play with it the way you install a new app from Play, you won't miss it.

Omni's performance app is "kernel tweaker" from Play. It is there since day one. I just added the GPU settings page. Carbon use the same app too. It has the sliding drawer style like Play. In menu, you can also find an option switching to tabs. If you ever click the menu at top right, you will find the option and find your answer right away.

I have put a tips in post#2 too. It's there for a reason....

Hi Daniel,

Thanks for your hard work and give us those firmware to improve our GT 7.7.

I tried to install your exFAT fix from recovery but I am getting a "Failed" error message.

I tried to install it the same way as if it was a firmware using the "install" menu.

Many thanks.

Thanks for your report. I think I forgot to mount before setting permission but it might still work since the files are already copied. I'm away and don't have my tab in hand to test.

You may test if it work. If not, I can made another zip after return home tomorrow.

I'll put it in the next build if it work.

Difference betwenn Carbon Rom and this Rom

Hi,

what is the difference between Carbon Rom and this Rom, both made by Daniel. Is this Rom also in german language?
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
The roms are not actually made by danielhk but are in fact ported to our device by danielhk. On that note and after trying to port a rom to our device myself it is not a simple thing for our devices. With out his skills there would be no kit kat at all for the 7.7's. As far as the diffs between omni and carbon i would suggest visiting the web sites that do create the two roms and discover the differences that way.

No battery drain at all..

Ths again...
[Galaxy Tab 7.7 Android Development] werich:
Using Omni 4.4.4 for half a year now I'm also very satisfied - stable, 3G/WIFI/BT and no battery drain.

But one thing bothers me:

Is there a possibility to alter the color saturation just like the DNIe settings of Samsung-Stock Roms? The standard of Omni ROM seem much oversaturated with a reddish tint, which is a pitty with the nice AMOLED screen of the p6800.

Is that setting possible with another KitKat ROM like SlimKat? PAC-ROM 4.2.2 had this option!
[Galaxy Tab 7.7 Android Development] teto84:

Serious FPBug found on Exynos 4210 (this device) they found it and fixed it.

Hello. I'm sorry if this is the wrong place to type but as Tab 7.7 and Tab 7.0+ forums are not so active I decided to use the last active thread ;)

By chance I have Note 1 (Exynos 4210 device) and Galaxy Tab 7.0+ (also Exynos 4210 device) and I came across this thread about some serious kernel bug that has been on Exynos 4210 Devices a long long time. They finally found the cause of the bug and nailed it after months of hunting.

I'm wondering if the Tab 7.7 or Tab7.0+ community is informed about this. I can't understand much of the stuff myself but it seems serious enough to cause a lot of weird problems.

If this is not fixed already on Tab 7.7/7.0+ then do you think if anyone has the willingness to put effort in and put the fix in Tab 7.7 and Tab 7.0+ kernels?

PS.

I read that latest Omni 4.4.2r2 (This very thread) for Tab 7.7 could have possible working AptX. No one has said anything about it working or not working though and it's been months. I only have Tab 7.0+ but it should on paper also support AptX with Samsung firmware. Seems the last Omni for 7.0+ is not as advanced as for 7.7 so I cannot test AptX even though I have headphones that support AptX.

Rom is nice.. I´m a sucker for anything light and fast. Testing it for two weeks, and the report:

1. Diceplayer 2.0.50/PlayerX 2.0.2 crashes when playing videos (wmv and mp4), but playing via Quickpic works fine (except wmv).

2. Performance settings fc - manually setting UV/ scheduler/system tweaks and so on works as always.

3. Installing Crossbreeder always helps extending screen time for me from 4-5hours to 6-7 hours depending on screen brightness, mine is around 10% all the time..This has been a huge issue for me regarding any roms 4.2-> as screen time is no where near cm10 @ 9-10 hours of usage when browsing without javascript and mainly reading in airplanemode.

3. What happened to the smdk4210 settings in 4.2->, the one where we could set screen temp and modes and so on..

Does anyone mind if I post in this thread regarding building this rom?

I won´t be able to "contribute" in development before beginning of february, hopefully there will be something left for a noob to do :)

cheers!

new 2013 12 11 build

Could not wait to flash, therefore I tried the new build meanwhile today's breakfast.

To make it short:

1) Came from the last CM kitkat build with dirty flashing + my last gaaps I had on the sdcard --> boooting fine --> optimizing apps fine --> as starting apps --> repeatable hot reboot (tried 3 times).

2) So I had gaaps in mind because I did not downloaded a new build --> flashing without gaaps --> same as before: hot reboot cycling after just saw for 2 seconds the homescreen

No time left this morning: so I will try again in the evening after doing TB and then a full wipe and afterwards restore of the user apps.

Maybe someone can report his experience meanwhile here!?

It may be also just related to some autostart apps I have (trickstermod, brightness controll....) ... for luck with an CWM backup it is safe to simply try. .. But the first 2s scrolling on the on the homescreen seemed to be promising fluid. so excited about daniels work....

Cheers!
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have tried many combinations. Dirty flash for OmniROM seems not working. It is not gapps related. Both my Nexus 4 and Nexus 7 are the same. AOSP base SlimKat is similar.

Puh that took a while…

Complete clean flash, adding all my build.props and kernel tweaks back,

add blocking, changing fonts and settings,

and MOST important remove all this gaaps junk which nowadays come with the gapps package and other apps in the roms (who needs an office and 3 music applications on a tab?).

plus's some greenify and auto start killing here and there....

Finally after some reboots: this build its definitely FASTER than all kitkat builds until now! Very happy with this one.

bugs:

- Seems that there is absolute no way to disable wifi! Help! This is somehow annoying because of battery drain, wifi-free sleeping and also possible security leaks.

- the "rotation snow" is still there. It is a bug, but personally I like it! ;P

[Galaxy Tab 7.7 Android Development] ZhenMing:

For the moment, that is what I tested so far for ART.

Anyone able to make the Bluetooth work? I just cant turn it on.
[Galaxy Tab 7.7 Android Development] sbkoh-xda:
Sorry I was mis-led. Switched to ART in Developer Options and rebooted fine, only to go back to Developer Options to realise that runtime is still Dalvik and not changed at all. :(
[Galaxy Tab 7.7 Android Development] ZhenMing:
ART will not work with Xposed and it will stop you changing from Dalvik.
[Galaxy Tab 7.7 Android Development] GNUDroid:
art and wifi-problem

I switched to ART and it survived a reboot for me. I don't have Xposed and until now everything is running fine.... but I did not tested to much apps with art until now.

This ROM is quite good unless the known problems (mainly phone). I can highly recommend to remove many apps which came by the ROM and especially by most gaaps packages. Additionally some kernel adjustment and now it is fine.

Actually the speed now feels again like the last 4.3 build from daniel which was great!

Some steps should do to be happy with this ROM:

- remove all unnecessary apps for you. There are many apps like "system app save remover" to to this.

- edit build.prop with your own tweaks collection or make at least some standard adjustment with apps like "pimp my rom"

- take a look at the autostart apps and additionally greenify almost everything, Titaniumbackup will help you to convert also many system apps to user apps for that job.

- "trickstermod" is cool to decrease the up threshold for the cpu and also allows many other kernel-tweaks, which are really necessary with the stock kernel-settings. ... look for example in i9100 related forums for reasonable settings.

Still the bug not to be able to keep WIFI disabled is annoying me! I also tried fix-permission scripts and search for app-permissions which could activate wifi on their own... no luck until now with that. - So if anybody finds a solution, please post!

All together: My daily driver and great work from Daniel!

[Galaxy Tab 7.7 Android Development] daniel_hk:
You need to do a wipe data to recover. Do a backup on /data after restoring all apps.

WiFi ON/OFF is caused by the old radio driver from samsung. Seems mobiledata has the same pin as WiFi. We can only have either one now. No source on the libsec-ril which is still ICS.. Trying another approach now.

Good luck!
