Jacob, maybe you have to change front cover assembly (which includes your touch panel) or your main flex (it's the riban between your mechanic-slide).

Philemon, Your problem comes from the on/off flex, it contains the secondary mic.

Kenzo, I think for your earpiece there are no need to change it, just adjust your earpiece proprely. But for the mic, I think the problem comes from the flex you replaced, you have to change it. Maybe the new flex is not good.

Isaac, do a software repair with your Blackberry Desktop, thats all. Don't worry, it's nothing.

Louise, tu peut la changer toi-même. Mais voilà, si tu t y prend mal, tu pourrai casser un composant ou déformer ta cosmétique. Tiens, tu suis ce guide: BlackBerry Curve 8520 Motherboard Replacement Ensuite une fois que tu as atteint la carte mere, tu en enleve la vis noire et tu remplace ton trackpad. Si t'as d'autres questions n'hesite pas.

I think it's a bad idea. The logic board that you are seeing on these images are water damaged boards. So the values are maybe not good. In this case I think the problem comes from Camera flex, maybe they're cut anywhere (micro-cuts). For my part, you have to change the camera and make cross test.

Hi tourangelle, it's a software engine problem. You have just to software update your phone. Here, this the software that you have to use: http://www-support-downloads.sonymobile.com/Software%20Down...-2.11.12.5.exe Before anything, your battery must be fully charged. Install it on your PC. Then run the program. Choose the model. Launch. Take out the battery, put it back, and keep the back button pressed. Plug it to your computer (don't forget, you have to keep the back button pressed). When the software update starts, you can release the back button. Wait until it finish, restart your phone. It's finish..

Sorry Tif, but have to change your motherboard. There is no solution.
