[Q] my note doesn't boot up

i was trying to downgrade from revolt rom (kit kat 4.4.4) to sweet rom (jb) 4.1.2
so i flashed philz kernal so that i could install the rom
after that i wiped every thing and installed the rom
then once its booted up it stuck in setup menu
then i installed speedmod kernal
and rebooted system, then a black screen appeared and also no recovery
i went to download mod then i found this
custom binary download : yes (2 counts)
current binary: custom

and also a yellow triangle appears if i tried to boot up the sevise

please tell me what to do or refer to any helpful topic
