shashank, remember that all that this kit is trying to accomplish, is to close cracked solder joints. Most of the time the extra few pounds of torque provided by the kit, will close those cracked joints. It is not a permanent fix, nor is it a sure thing either. It all depends on the individual logic board and the damage to the solder joints. I strongly suggest a reflow with this kit. The chances to be successful is greater with a combination of RROD kit and a reflow. Here is a guide for the reflow. Of course, a permanent fix would be a total reball. for a reball to be done, you will need the stencil, a rework machine as well as the proper reball temperature template. If you do not have those tools, you can not do a reball. This will give you a pretty good idea on how to do it. Hope this helps, good luck.
