Hi,
I am using nokia6681 mobile I updated latest firmware (v 6.09.00) last 2 weeks back. After that network signal problem no coverage in my mobile
I changed the battrey and Adapter same problem, and I checked with ather mobile same sim card its working.
Please help how to restore old firmware to my mobile.
Thanks in Advance

The older firmware won't be available , simply because the new firmware is considered as improvement .
Anyway , two things you can try first :
1) flash the Firmware again , and/or
2) do a Hardreset , see my post here :

Have a Backup of your Personal Data and restore after . Nokia default security code : 12345
BTW : was the phone sold as a locked phone (to a Network) ? It could be a cause , when the Phone wasn't properly unlocked .
