My Nokia N73 now is very laggy. It sends text message too long and it hangs while sending then back to normal after it sends the message. There are no files in the memory (both phone and memory card). Others told me to update the firmware because my N73 was repaired and reformatted by a technician and after a few days. This problem happened (laggy, takes too long to send messages). So I tried to make a backup and update it but the Nokia Software Updater won't work. I installed PC Suite and Nokia Software Updater but it still won't work. I already installed the latest .Net Framework from microsoft but still it won't work. Missing major components. Please reinstall. That message appears. I reinstalled it but it still won't work. Help please.
Note: After I installed SMS Accelerator from Nokia.com my phone I think was back to normal. Less laggy and it doesn't anymore hangs when I send text messages and it sends text messages normally again. But I don't want it to be messed up again so I want to update the firmware but I can't because I the Nokia Software Updater won't work. Help guys.
