how do I change a Flex Cable in a mobile phone?

I have a U900 and needed to replace the flex cable... I bought a new one - but..... how do I remove the old one and put the new one in ??

thanks

Each end should have a ZIF (Zero insertion force) socket. On each side of the flat socket is a very small block you have to pull or push these two little pins, together. Usually if you try one side at a time, it just rocks back and forth. I've found a pair of needle point tweezers with one point under the little block at each side is perfect. When both sides slide forward, it releases the pressure and releases the contact bar pushing down on the exposed contacts at the cable end. It should almost fall out and require virtually NO force to pull once the clamp is fully released. Note whether the silver contacts are facing UP or DOWN. You do the opposite to put in the new cable. Slide in the end of the cable, into the socket with the silver contacts facing the same way as the one you removed. It should take NO force whatsoever. (Hence the name, ZIF socket) Hold the end in place and then slide the little clamping bar back in place. It will be relatively hard to snap the locking bar home. Once the locking bar is in place, the cable end is locked in place with the bar pressing down to make sure the silver parts make good contact.
