Thanks rammkorn for the link. Did restoring gsmparam.cfg fix the internal speaker issue as well? Is it possible to modify gsmparam.cfg to restore a specific IMEI? Can you please share your copy of the file?
Thanks.
yes after I've restored my gsmparam.cfg I've solved all my problem. In that file there are encoded my IMEI and my MAC, so I can't share it, but you should have your copy in your mobile, in the windows folder. I don't know if there is a way to edit it.
