Earlier, I have been compiling several ROMs for the galaxy tab (P7510/p4wifi) based on KitKat 4.4. I now decided to move over to OMNI ROM as base: http://omnirom.org/
The nice thing of OMNI in my personal opinion is smoothness: it is relatively low in features, but at the same time it is not that resource hungry as some other ROMs. The end result is a smooth ROM.

Changelog of 15-Feb-2014
-Omni codebase of 14-Jan
Several small fixes, nothing spectecular

It features the Infamous kernel (same kernel as for JB4.3, without SELinux). The zram code has been optimized (based on google advice for low-RAM devices) and is enabled by default.

To see the additions on top of Omni, check github (additional patches are always shown on top):
Frameworks
Settings
OmniGears


First installation:
-Boot into recovery
-Factory reset
-Wipe system partition
-Install ROM
-Boot tablet (there sometimes are bootloops if gapps is flashed directly on top of the ROM without first booting the ROM)
-Reboot recovery
-Install SuperSU: http://download.chainfire.eu/371/Sup...erSU-v1.85.zip
-Install gapps (you should use a package specifically for KK4.4 and with the old-fashioned updater-script! - don't worry if you install an outdated gapps packages with the correct updater-script, as long as it is for KK4.4 the apps in the gapps package will be automatically updated -> only small gapps packages fit, e.g. banks core of pa 0-day gapps mini)
-Boot it up

-> some people report issues (e.g. bootloop or crashing gapps) if they flash ROM, gapps & supersu in a row after fully wiping the tablet. In that case, wipe again, flash ROM, boot the tab, reboot to recovery, and then flash the rest.
-> if coming from stock ROM, a factory reset may wipe you entire /data partition, so you loose you sdcard contents as well (I think this only happens with CWM, but I'm not sure)
-> in CWM "wipe system partition" can be found under mounts, and is called "format /system"
->If you get the message 'This package is for "p4" devices this is a "GT-P7500"' (or something likewise) update to a recent CWM or TWRP

Update installation (OMNI -> OMNI):
-Boot into recovery
-Install ROM
-Install SuperSU (in the SuperUser app you can create a script that will automatically backup/restore SuperSU on ROM updates so you don't have to reflash SuperSU).
-Boot it up

You can download any gapps packages for kitkat that you like, but one that many have used successfullyis PA 0 day gapps:

What does NOT work?
-There are graphical glitches. Although they mainly have been solved there seem to be some remaining issues with hwcomposer that may crash the tab.
-Bluetooth audio does not work (other Bluetooth functions do work).
-HDMI output (may be fixed according to some posts, didn't test myself yet)
-HD movies (in e.g. youtube) may stutter

Smoothness advice:
Go to performance settings:
-Overclock CPU to 1400MHz (Do this at your own risk!)
-Set IO scheduler to CFQ
-Keep governor on Interactive
Go to developer settings:
-Set the three animation scale options to 0.5x
-Activate "Force GPU rendering"
-Active "Disble HW-overlays"
-Set background process limit to 4 processes

(if performance/developer options are not yet shown, go to settings>about and press build number 7 times)

-> Thanks to all forum members contributing to this list
-> Do it at your own risk!
-> Don't complain about limited battery life (ROW+interactive+1000MHz leads to better battery life for sure)


Some other tips:
-For improvement of sound quality, you can use Viper4Android
-For more volume only, SpeakerBoost is earier to use
-For netflix, head over here: http://forum.xda-developers.com/show...&postcount=445
-To be able to use Flash player, use a browser that doesn't use the kitkat browser engine (e.g. firefox can be used). Download flash player from adobe website (thanks to AAccount for finding out!).
- If you can't see your internal SD on PC: Go to Settings -> Storage -> 3 dot menu -> tick MTP.
-To use the multi-window feature, go to the recent apps screen, press&hold an app, and select put aside.

Just wipe everything and flash the ROM.

You need to separately flash SuperSU. SuperSU can create a script for backing it up, so that on future ROM flashes you don't have to repeat this.

Doh, its a p4wifi ROM. If you don't use 3g, flash a p4wofi recovery first, reboot, and flash again.

Flash P4wifi recovery, Then flash this ZIP again


Bad to see that it is really not for the GT-P7500 . So i will not update.... i really need my 3G
Why it is so difficult to get 3G working Did 4.4 change so much?
