|I'm guessing the on the locked firmware the code for the memory reset goes something like this: |
1. set some variable in flash mem somewhere to 0 -- call it 'flashupdate'
2. do wipe out memory flash thing -- zero out... doesn't f you clobber ' flashupdate' as its already 0
3. relock mailstation by putting the mail.mymailstation.com etc back in.
4. set above variable to 1
And in unlocked versions it just does step 2.
Now if I try to to pull the plug at just the right time [ and I have tried a few times ], before the mailstation stuff is copied back in, and there's some code on startup if flashupdate==0 then jump into reset menu, then it's back to square 1.
Just my guess anyway.
CHECK mailstation internal pics posted thread and inside mailstation thread for info on the the chips.
What does it take to wipe the flash memory? Any special hardware or is it it a matter of connecting certain pins to ground?
I can afford to break 1 so I might try it myself. I'd give it a maybe 50/50 chance of success, if its done as above zeroing the flash won't help, but if they just couldn't bare to reverse the logic, it might.
