Earlier, I have been compiling several ROMs for the galaxy tab (P7510/p4wifi) based on KitKat 4.4. After my experience with Omni was not that bad, I decided to move over to Nameless ROM, where I have become a core member of the team: http://nameless-rom.org/.
Changelog of 23-Mar-2014
-Many upstream updates from nameless & CM
-Updates to CustomLauncher (I have had no more FC's)
It features the Mackay kernel (it is a kernel named ICS_2014, because I worked on this kernel for stock ICS and CM9 as well). The zram code has been optimized (based on google advice for low-RAM devices) and is enabled by default. I also improved the OC code and changed voltages.
First installation:
-Boot into recovery
-Factory reset
-Wipe system partition
-Install ROM
-Reboot system (there sometimes are bootloops if gapps is flashed directly on top of the ROM without first booting the ROM)
-Reboot recovery
-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 - don't worry if you install an outdated gapps packages with the correct updater-script, as long as it is for KK4.4 the apps in the gapps package will be automatically updated -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)
-Reboot system
-> some people report issues (e.g. bootloop or crashing gapps) if they flash ROM & gapps in a row after fully wiping the tablet. In that case, wipe again, flash ROM, boot the tab, reboot to recovery, and then gapps.
-> 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 (Nameless -> Nameless):
-Boot into recovery
-Install ROM
-Reboot system
