Reflowing the RSX & Cell processor is not enough for the 60Gb model (COK-002)
Firstly, you need to remove the heatspreader from the RSX (check youtube) otherwise you will damage it. The southbridge chipset near the HDMI/AV ports needs to be reballed/reflowed as this is the main controller for the video/SATA/NAND etc.
Vorlone - no wonder you can't repair them... Your reflow profile is completely wrong. Bottom heater should be doing 70% of the work, top heater does the other 30%. You should be heating the underside to ~180*c and then use the top heater to raise the temp of the die to ~220-225*c or until the point of liquidus
Please don't say you use a heatgun...
