My phone is too slow becuase of this Belle. Is there any way to do hard flash of my phone without going to Nokia Service centre. Or can you send any updates for Belle so that my phone will become easy to run. I cant even take backup of my messages and contacts becuase of this slowness. I have around 2000 SMS in my phone and I think this is the cause. Could you please let me know process for hard flash of phone ?
Please do something for Belle, its very very slow and unresponsive.
