Wont go into download mode

[DroidKillaz]

i wanted to go back to stock on my g900w8 so i flashed using odin, when it booted back up it keeps popping up "unfortunatley this and that has stopped working" and wont let me get out of it no matter how many times i press ok. the phone is now only one 2 percent and i was going to try and reflash it i was wondering maybe thats why its not going in download mode maybe?
