I think u should first see that the phone is startin or it remains in white screen hang. If the cell sound start
up sound then only u should see in display section other wise it is un use to work on it becoz u have damage the omap by over heating the kepad ic.becoz it is only near to it

you have only one problem,"OMAP",,, KEYPAD and WHITE SCREEN - HUNG are OMAP problems,,,,first you have keypad problem because there is open contact(s) under omap,, data from OMAP going to keypad ic is not complete,,then you applied heat to replace ic, problem on OMAP worsen open contacts under omap get more that is why your unit now is hung,,,you can fix your unit by removing GLUE and put new OMAP,,, actually what couses your problem is the glue,,if OMAP wasnt glued you can just reheat it and right away its fixed,,but since OMAP is glued,reheating will only make problem more bad,,glue will expand a bit and will result to more open contacts under OMAP,,this is also true on some DISPLAY problems,when there is missing data going to LCD IC'S,,,hope this analysis will answer many of your questions,,

if you want to check,,use your multimeter and check all connections on lcd ic,,sure there is missing connection(s) from OMAP
