WARNING​

If you have i.e.

dalvik.vm.heapstartsize

before tweak lines in build.prop, You must delete them all which are :)

SEEDER - entropy generator​

You must use kernel without FRANDOM, or original (only original is without frandom now). Only on that will work.

http://d-h.st/P0j <- just flash via cwm

after boot up go to terminal emulator

type :

su

allow permissions

next:

seeder

you welcome

there are drivers for processor, but phone is more laggy after it for me ;) http://xdaforums.com/showthread.php?t=2352724
