Unhappy Help me with Stock bootloader...

Hello,

2 days ago I flashed the wrong bootloader with teamwin recovery project v2.1.3
Official I have the Liberty tab G100W but installed a lot of acer roms custom kernels. This time it went wrong and I really don't know how to fix it.
Is there someone that has the official bootloader and kernel and rom or someone who knows what combination bootloader kernel & rom works?
I really hope someone can help me.
