Finally got my 2GB card to flash...
Didn't matter how I formated it (and trust me, I tried any number of ways from any number of posts here and on XDA) all I'd ever get was the flash of "Loading - No image file"
What solved it was an obscure post by someone using Gparted Partition Tool. So, being a RL tech, I actually had a copy of that laying around in my desk! Popped it in, reformatted the card for the 20th time today, popped the file on (with lowercase extension, just to be safe) and BAM, it worked! So, yay, I'm on the new radio for what it's worth
