My Clip's working fine now!
Please, could you be more specific? What build are you using?
I've tried builds 21578, 21593 and 21613 and still can't get past the bootloader. Old build 21506 works (as well as many other older than that), but with the known random freezing issues.
I formatted the device and that didn't make any difference.
The bootloader build I have is 21444, can that make a difference? I tried compiling the bootloader from source... well actually I did it, apparently the compling process was successful, my Clip did the firmware upgrade but then it didn't work. I got a little scared and had to go back to build 21444 of the bootloader. What could I have done wrong? Where (or how) can I get a 'good' recent bootloader build?
BTW, I have a 4Gb Clip (v1, of course)
