i found a doc (1952 atm) a thread, where the user actually had kpcol0 marked on their board but figured it was wrong because it didn't work so i tested my usb cable on another device and it works i then started trying different testpoints. i think the four near the battery might relate to usb. i grounded some of them and then when i plugged my device my usb port overcurrented O_O oops and all the usb devices on the hub reset O_O oops 1954 1956 I FOUND IT BY TRIAL !!!! THE DEVICE SHOWS IN THE DMESG AGAIN !!!!!! O_O !!!! :D ! 1958 it's the lower-left-most test pad, the closest one to the warning image of somebody touching something to a test pad, next to the notch on the board and the card slot. it's in photo 3 on page 2 of the fcc doc. i found it !!!!!!!!!!!!!! i guess i'd better reflash the phone. i'll share what i found on my xda thread. 6/24
