I am trying to apply Jelly Bean firmware update on my Galaxy S2 X, but everytime I try to, Kies dies at 0% of the firmware update, without any error message.
I tried uninstalling and installing Kies again. It is up to date. I also tried running it in Windows 7 mode and XP SP3 mode (I'm on Windows 8 64-bit).
I did a factory reset of my cellphone, and still encounter the problem.
Is there any alternative or way to fix this?
