I have unlocked sim and bootloader (official way) and my flashmode and fastboot is screwed i cant get into either D:

Same here mate .. my USB is not working after trying to flash the stupid FXP 117 rom .. I did a restore of previous ICS Nordic official rom but it said some SD ext.img not found during that restoring process (i dunno wat that means) !.. Now i am not able to get into fastboot or use flashtool the green light and the blue light comes up but in fastboot it says waiting for device and in flashtool it says device not connected i am literally scrwed .. everything else is working ok except the USB not even gettin mounted .. how am i to proceed from here .. please can some smart devs here in XDA help me ??

Remove the battery for a while 3 mins or so, then flash original ftf. Do not boot before hand, just try and go straight to flash mode.
