According to the usblogs from Kevin:
Erase Flash 810000
Write Flash 810000 3150
...
and from remote_info.h:
// fl_base, fw_base, config_base, fw_up_base, fw_4847_off,
cookie, ck_sz, endvec, micro, fl_sz, ram_sz, ee_sz, usb
...
// 9 - 360, 52x, 55x
{ 0x800000, 0x810000, 0x820000, 0x810000, 4,
0x4D434841, 4, 4, "PIC18LF4550", 16, 2048, 256,
"Internal" },
It writes directly over the live firmware in fact.
