You need an Mbus/Fbus cable running through a COM port to reset SP locks, update FAID and change IMEI.
I had the same problem, i bought a data cable to update my phone software because the store where I bought it from said it could be done. Then they told me I needed a flasher cable instead of a data cable. So I returned the data cable and got a flasher cable.
Then I found out I needed both a Flasher and Mbus/Fbus cable to fully update phone software.
Now that I have both, I have had no problems
Hope this helps
