TF700t Boot problem

Hi, im new here and i have problem with booting up my TF700t...

I did the process uncountably many times with clockwork and twrp recovery, i wiped out completely everything and i can say i tried everything to make it work... but when tablet tries to boot, there appears asus logo, then the four penguins show up with some codes, the last one is "preinit : finished - booting your operating system" ... sometimes there appears another two codes under that, but only sometimes. Then the crombi kk animation shows up and get stuck. This is repeating without end. I tried everything on all the forums i managed to google out but the problem still resists. It looks like my last chance is to post my problem here.

Thank you and sorry for my bad english
