May be I can help you.
First of all you need to download Android SDK from intrenet. Then you need to flash yours phone recovery manager [ you see now android logo and exclamation mark in a triangle].
I will upload back up from my phone[ it is the same but it is from Serbia telecom and don't know will it lock your sim but it should not]
When you install SDK go to C:\Program Files\Android\android-sdk\platform-tools
In this folder you should see little file called 'fastboot'.
Then go to Start\run and enter "cmd'. Win terminal should appear.
In terminal enter this command cd C:\Program Files\Android\android-sdk\platform-tools
Now copy file cwm_recovery_racer2.img
to this folder.
Turn off your phone. Press power button and volume + button for 5-10 sec, connect your phone and computer with usb cable. If copm ask for drivers you should install it.
When everything is set in terminal enter command fastboot
, then fastboot flash recovery cwm_recovery_racer2.img
[note that file cwm_recovery_racer2.img
must be in C:\Program Files\Android\android-sdk\platform-tools]
. wait for 8 s and you should see done message.
Now you need to copy folder clockwork
to your sd card.
diskonect phone from usb, turn it off, press power button and volume - button for 10-15 sec and if everything go well you will see black screen with some options. Go to back up and restore
using volume buttons and confirm with Home button. Then go to restore and pick folder that appears and that it restore will begin.

This phone have problem with drivers so i recomend you to install unlockroot
and from Start\all programs\unlosk root\ install driver[ you will see it]
