In Summary:
I need to downgrade my firmware to fix a problem that has occured since using nokia's update tool. I would like to know of a program to upgrade / downgrade firmware on a nk6630 on voda via the data transfer cable supplied with the phone (used this to apply the update also) and where to get the firmware files from.
In Depth:
Saw nokia's firmware upgrade tool on their site and thought... why not? (I understand the "if it ain't broke, don't fix it" rule now!). After installing every 3 - 5 incoming / outgoing calls, calls coming in or going out do not connect. This started the day after the update was applied. I would like to go back down a few versions and see if this resolves it. Any help would be much abliged.
Thank you
