18 January 2014 - new overclocked kernels repository; (note - each kernel is in its own CWM upgrade package - you first have to unzip this zip file in order to get at all the kernel packages inside it);

TIP: I find the "T14" builds better in terms of speed and battery usage - but the "T13" builds run cooler.

* This mod is based on; kasty-cube_u30gt2-422-206_20131029-rooted4

* This mod is set for 4GB data partition.

CHANGES to the Kasty ROM:
1. Some unnecessary library files (relics from removed Chinese apps) have been deleted.

2. Multi-user mode is enabled by default (fw.max_users=5)

3. Some extra user apps added (e.g., Dolphin browser, Reboot, Master Key dual fix, Nova Launcher, Bluebox security scanner, Xposed Installer (has to be enabled first), bash, Terminal Emulator, etc.)

4. persist.sys.ui.hw set to "false" (allows some games to play)

5. ro.rk.systembar.tabletUI set to "true" (solves wallpaper stretch problems)

6. Timezone set to London

7. Language/locale set to GB and English

8. Tablet set to announce itself as GT-P7500 (Samsung Galaxy Tab 10.1) – this is for better compatibility with Google Play apps

9. (January 2014 mod only); this mod has an OVERCLOCKED KERNEL; the cpu is clocked at 1800mhz and the cpu is clocked at 768mhz; the DDR memory is not overclocked. The kernel is based on kernel #12 from the freaktab forum 900supersport ROM, using the "T14" DarthJabba build specs (see the discussions on the numbered test overclocked kernels on the this forum). If you are worried about overclocking and what it might do to your tablet, then this mod with the overclocked kernel is NOT for you!

NOTES:

A. You may need to reboot the tablet once or twice for things to settle down completely.

If you are worried about bricking your tablet, then STOP RIGHT NOW !!!
