Hi,
In most dct4(wd2, tiku) phones there are two areas with flash imei - the permanent
flash area ( flash imei, faid, working parmeters, etc) - the top of the flash and backup of the flash
imei in PM area - the bottom of the nor flash usually.
In normal phone when the algorithm is loaded, it first backup the permanent
area to ram, then you can erase it while flashing, at the end of flashing you
send permanent data restore comand to restore the ram backup to flash.
If something bad happend - example you disconnect the phone while erasing the second area,
the values will be gone from RAM also the permanent area will be 0xFF. But your phone will have good imei after second
flash, because on first bootup in normal mode, the phone will get the backup
from pm and write it to the permanent flash area.
This is not the case in 1100, because there is no pm backup, so flashing in
many cases can kill the phone flash imei.
Regards
