Firmware Upgrade Successfully

I finally successfully upgraded my E71's firmware. After resetting several time due to lost connection with the phone during upgrading, i finally took the last option, reset to factory settings and guess what? It worked to fix my problem after upgrading my firmware

So the problem lies during the upgrade. After the phone restarted, i couldn't see my firmware version along with other information with special number inputted on the phone (for example *#06# to see the phone's IMEI or *#0000# to see phone's firmware version). But now everything is working normally and i hope nothing will happened in the future
