Please help, I'm tearing my hair out. I wanted to update to ICS Android 4.0 on my Orange branded S2 NFC. I was told by Orange support to download Kies. I did, had a few problems getting the phone to connect to the software including a few driver crashes. After it finally connected, it offered me ICS which I accepted. But every time I have downloaded the update it then fails saying "Failed to run firmware upgrade. Unknown error occurred."
I have uninstalled kies and the driver from my PC (windows 7 home premium 32bit) and reinstalled to no effect. Turned off the phone, taken out the battery, turned off wi-fi and data.
If it wasn't for the fact the orange "signal boost" app has been quite useful in my dead zone of a flat I would root the phone and unbrand it and download the update off the net.
Please please can someone help before I destroy this phone.
