the BT and the L1

i soldered both in and voilá it worked ... but i forgot to plugged the 3 & 4 controller ports in again. so i took the hdd and dvd drive out and i saw that the L1 wire got loose ... when i was lookin at it i saw that the resistor got knocked out too ...
so right now i cant flash the chip again, but thats not the problem ... i dont know if that resistor is necessary ... because i could just buy another chip and put it on the pin socket ...
does anybody is able to help me?
