samsung galaxy s2 Complete(Write) operation failed. Now Bricked

Hi all,

I really need your help.

I have a Samsung Galaxy S2 (GT-I9100G) unlocked from factory.

It comes with Android 2.3.6

It´s from US, but I use it in Argentina

For some reason I couldn't find any update to ICS for it (neither Kies nor OTA).

So I decided to do it manually by using Odin etc etc.

The process failed with this error: samsung galaxy s2 Complete(Write) operation failed.

So I unplugged the phone, and since then, when I turn it on, it ony displays Warning-Phone icon and cannot be set to download mode again.

What can I do in order to back to its original state? (Android 2.3.6) or and Ice cream sandwich suitable for my GT-I9100G

I think the problem was that the downloaded files (.md5 etc) were wrong or not for my model.

Can I use odin again? Or I shoud first put the phone in download mode?

I've tried with a jig, but it did not do anything.

I really need the telephone :-)

Thanks a lot in advance.
