Reply for what?

You did not backup your data.

The device is in recovery mode.

Restore it as new.

Move on with life and hopefully learn a valuable lesson that backing up your data is YOUR responsibility and is very important before attempting updates.

"please be informed that i didn't make a backup for my iphone 4 and i didn't conect it to the itunes or enable I cloud to make a backup "

Wow. You were trying hard to lose all of your data.

"this mean that I will loose all my contacts, picture and data saved on my mobile."

Yes. You will certainly lose everything, as you failed to backup your data.

Not sure what your question is.

You made a terrible mistake and failed to use your iphone as it is designed. You have lost a ll of your data.
