[ROM][KK 4.4]Nameless ROM GT-P7500/7501/7510/7511 (unofficial build - 13-Apr-2014)

I was compiling several ROMs for Samsung Galaxy devices. With KitKat coming up I was able to maintain my ROMs for the S4, but was not successful with a ROM for my Galaxy Tab 10.1 (GT-P7500).

Thanks to the incredible support of kasper_h I was able to take over his work and create this KitKat ROM for the tablet! Unfortunately he discontinued the work on this ROM because he will move on to a more advanced tablet. I wish him great success with his new tablet and want to thank for his work for the 10.1 tablet!
With kasper_h agreement I take over and will maintain future updates of this ROM.

Reminder:
At this time this is an unofficial build of the Nameless ROM! Several parts of the Nameless sources have been patched by kasper_h to get Nameless working on our beloved old 10.1 tablet. Some functions of the ROM are not 100% the same as you would see it on a Nameless ROM for other devices!

Changelog of 13-Apr-2014
- Updated source codes to latest releases from NamelessROM & CM
- Recompiled and published
- Small simple boot animation (as the original Nameless boot animation seems to make problems)

Older changelog in post#4

This ROM features the Mackay kernel (it is a kernel named ICS_2014, because kasper_h 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. kasper_h also improved the OC code and changed voltages.

First installation:

• Boot into recovery
• Factory reset
• Wipe system partition
• Install ROM
• Install gapps (you should use a package specifically for KK4.4! - don't worry if you install an outdated gapps packages, as long as it is for KK4.4 the apps in the gapps package will be automatically updated.
• Wipe dalvik-cache and cache
• 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.

• Boot into recovery
• Factory reset
• System wipe (to get rid of old GApps installations!)
• Wipe system partition
• Install ROM
• Wipe dalvik-cache and cache
• Reboot system
• Reboot recovery
• Install gapps
• Reboot system

==> Sometimes you get problems with GApps, even you did factory reset and flash a new GApps version. The reason is that Nameless build in the updater-script a routine that calls any batch saved in system/addon.d. Most GApps installations place there a batch called 70-gapps.sh. This batch file saves all GApps apks and libs before the flashing wipes system and restores them just before the flashing is finished. And factory reset does not wipe system!

-> 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

You can download any gapps packages for kitkat that you like, but one that I use and tested is the minimal GApps from BaNkS.
