bretzeljoe, hello, I just read your replay and I have some points to highlight, first and the most important, the hack was originally designed for the early e30, so I must ask you about the version of your camera, is it from before 2013?
Second, You asked about the CRC, I will revise the procedures, but to clarify, my hack lays on the supervisor structure, it is the same that goes on use when you set it to high res from the supervisor menu, but it only while powered on or while not rebooted, and was said so, send me the files you created I will revise it to you.
Third have you done a comllete backup? I can get the sup for you from there, but only if it is a camera from before 2013.
I will look forward your answer, at this very moment I am on my way home, so I may have left a mistake or two, so excuse me.
Kind regards,
Gustavo Campos
