Hey folks,
Can you help me out here? :| My 5D3 is dead, stuck on firmware update.

Here's the story behind it:
I purchased it 6 months ago, almost new (7k shutter count). Was working fine with Magic Lantern for 4 months or so. Very minimalist usage. Didn’t shoot much.
So for two months I was using it only in video mode (with ML, without ML) and it was fine if we don’t count occasional ERR 80 showing up.
Few days ago I decided to remove Magic Lantern and install latest Canon firmware (1.3.4), I did the standard ML uninstall procedure (I’ve installed/removed ML on many cameras in the past years, so I know how it’s done). After uninstalling ML, camera still "worked" as described above.
But, after starting firmware update it stuck at 9% and I’m not able to resolve that issue with 5 different batteries I have and 4 different cards (both CF and SD) since then.
My question is, is there any way I can bypass this issue and install firmware on my camera again? I’m OK with malfunctioning/only video mode working and regretting the moment I started this fucking firmware update.
P.S. The added problem is there’s no official canon service center in my country.
