I have canon 600d
firmware 1.0.2
so the problem as i already told you when i try to record a video the err 70 appear on my canon screen..
then i found out in this forum that i have to try ton install magic lantern and i already did .
when i try to record a video or livemode, the ASSERT code appear but the err 70 still there .. and when i push the record button, the mirror didn't stuck, i mean like, 'clak' 'clak' ... i think it's the shutter .. if know what probably the problem is ..
sorry for may bad english
