what people are getting mixed up with is that when the programs fails with the error cal date empty : fail "" its not saying it is empty, its saying the complete oppersit.......... the cal date needs to be empty for the program to continue !
if you enter the service menu in the phone *#9998*324# then menu 4 2 2 you will see that the cal date is not empty, but for this program to go past this part it needs to find an empty cal date .
if you try to edit the cal date,even by entering 0000 00 00, it will still have a cal date of 0000.00.00, so the cal date is still not empty ???
so from what i can see, winimei can only work on an empty board that has no original cal date.
ELCO agrees with me that winimei alone cant change the imei on zxxx phones.
no matter what you do with the rx and tx usb and com port wires, it wont make any differance........
i hope someone can prove me wrong.
