HI Alvin,
i tried wit custom firmware 3.1 on iTunes 8.2 .. but it showed the error (1600).. wat does it mean ??
With custom firmware it doesnt show previous error lik iPhone isnt eligible to restore ..
Hi Komar,
You need to update your iTunes to latest version. Remember to disconnect your iPhone first before updating the iTunes.
Then, try to restore again with the custom firmware. If your iPhone requires you to activate through iTunes, download the one for official carrier user and vice-versa.
