Dear Jonathan,

Well done for your code download via the modem!  Sounds interesting.  
Have you documented your procedure anywhere?  Protocol/format of the 
data is probably* pretty similar to that over EXP, maybe?  :)  I don't 
have the means here to talk modem-modem to the device.

I was interested to read in your GPL-vio email that the PBL/kernel 
images were obtained by de-soldering the flash chips on an E3.  I'm 
keen to have a look at the E3's version of PBL (and thanks for sharing 
the symbols you'd deduced so far), but I'd prefer a non-invasive way of 
getting it out.  (So, JTAG or some EXP hacks - chicken and egg scenario 
w.r.t. reverse-engineering PBL's (v4) protocol though ;)  What is the 
state of the E3 whose flash chips were removed?  Were they read and 
then soldered back in place, or was it a sacrificial broken 
(before/after) E3?  IFF it was the latter I wonder if it might be 
possible to remove the OMAP5910 and beep out the JTAG pins to see if 
they go anywhere and if so, where?

Best regards,
