Yup dude read that already
I believe I cannot use the Firmware Update Method as ps.fi2 or ps.fir file isnt there
So I moved to Bootable SD Card Method
Followed "For cameras released after 2010" guide upto step 5. Got stuck on "6. Start CHDK manually by selecting the Firmware Update option in the Canon menus." The option wasn't there
EDIT Did
"Other methods for preparation a Bootable SD cardEdit
Windows Method #1: HxD GUI (for cameras released after 2010)"SUCCESS
Yeah baby Bring it on
