Default [Kernel/Recovery][P75XX] A1 Kernel V1.9/TWRP2.6.3.0

First of all Thank you for your patronage!!!

Before you do anything: This is purely at your own risk and I will not be responsible for anything that happens to your tablet. I flashed it on mine at my own risk.

Compatibility Information: There are 2 different versions. 1 for stock and 1 for Cyanogenmod. Even though the kernels are intended for the 3G tablet it will work just fine on a WiFi only tablet (like mine). This makes the build process less messy.

**Sources Fully documented v1.9 beginner friendly sources now available including the build script. If more explanations are required, please say so. However, remember that the explanations are not intended to be a blind step by step instructions of going from samsung source to A1.

TWRP V2.6.0.0: Please read: do not worry about any kind of "E:A: Render Error". This is a side effect of removing some image files to save place on the recovery image so it will fit on the 5MB. The error simply means it failed to show (render) and image file that it is looking for. This is not harmful at all. If you can't flash the recovery please try the dd method.
TWRP V2.6.3.0: There are no more E:A Render errors. All graphics that were removed are there. Also, the recovery will install supersu if no root is detected. That feature has also been restored. The kernel has been stripped of anything not recovery related to shrink it down. It also has selinux support which allows the "set_metadata" zip installation to work. The download is in the attachments below.

Great to see someone else kernel developing, could be the start of something here... Lol, I wanna give this a try but I think It'll stop 3G working if I flash the 7510 kernel.

Care to try the 3G version I just uploaded? I don't own the 3G version but I followed the same idea for compiling the 3G kernel.

Dang, you move quick, I've installed it but, how did you get the voodoo app to recognise the device as supported?

Scratch that, it was me being an idiot
