Firmware upgrade through Kies messed phone up

---

Hi,

My friend updated Galaxy S2 through Kies today for the first time. Everything seemed to go fine, but after successful upgrade, phone can't detect sim card anymore. Also when connected back to PC, Kies can't detect phone. What could be wrong? He haven't found any solution yet. Maybe need to re-flash with Odin

I wanted to upgrade my phone today also but I am afraid that I brick my phone the same way. We both bought our Galaxy S2 phones from Germany and live ourselves in Estonia. We didn't have any upgrades till now. It came with KE2 firmware from stock. Could it be that the problem is that buying region and region where we live/upgrade now is different? I'm just guessing. It's strange that official upgrade with newest Kies went wrong when it seemed to be successful. Hard resets also didn't help him. He tried other sim cards and these also won't work. Phone even won't ask PIN code when starting.

I googled every way and won't find that anybody have had similar problem after firmware upgrade. Does anybody have idea what to do, and what could have went wrong? I want to upgrade my phone, but don't want to mess my phone up

I appriciate when someone could help with information!

First step is a factory reset .
