Leif, I don't know anything about this stuff other than what I've read and played with on my WRTs. I'll tell you what I -think- I know and maybe that will get you a few steps further.
I think you have to crack one open and see what flash chip and processor is being used. You might be lucky enough that the HairyDairMaid JTAG software would backup one of those units if you could figure out what the starting addresses and sizes were. Again, I'm no expert but it might be possible to backup one of the SIP phones (assuming you could get your hands on one) and then upload that firmware into the phones you've got. I've got a JTAG cable that you could borrow if you felt adventurous. Dave On 3/28/07, Leif Madsen <[EMAIL PROTECTED]> wrote:
As an additional incentive, if anyone knows how to reflash to bootloader (it appears to need some sort of Jtag probably which is inside the phone case), and can get it to work, then I'll give them one of the Mitel 5220 phones. Just thought I'd giver another shot here :) Thanks! Leif.
