Echo on call - since 12070 fw update

[Snake.]

Since updating my Lumia to the latest firmware, I get complains that other side can hear itself, anyone experiencing this? How to resolve it? Is there a way to downgrade firmware?

The update was forced using the updatewp utility

If you have done a backup you can restore via Zune. If you have not done a backup (and you should always do backups when doing unofficial stuff) you have three options:

a) reflash the Firmware manually and risk losing your warranty

b) visit a local Nokia Care Point and ask to reflash the firmare/send it in for repair

c) live with it. Echos can also result because of bad Connection or the other Party using VoIP (at least I heard that at the german Support board).

Have you tried to hard reset the phone?
