can't get EPSi to change firmware

Hi,
I have bought an EPSi that is running on firmware 1.01 (reverb) and can't it to switch to C.01 (cab). I followed the instructions given by Logidy in their pdf (first update boot code, then replace the boot code epu file with the firmware epu and repeat the update process). The epu files have been placed in the EPDA folder as required. Can anybody assist me in getting this done? Thanks!

Are you using *just* an SD card (not an SDHC card)? Where are you running in to trouble? Are you getting an error code?

Problem solved! I sent a mail to the good people at Logidy and got an immediate response from Olivier, asking me wether I was on a Mac. I should try with a PC because Macs sometimes might break the file. Expert. That did the trick.
So in case you want to change the firmware on an EPSi, do it from a PC (virtualisation works, I only fired up my virtual machine inside the Mac).

Thanks for posting back to let us know about this! I am on a mac too and I would never have guessed it might be OS specific..
