i had it working like i was installing xex menu and dashlaunch etc.... then turned it off went and got a drink come back up turned it back on...i was on the pc then i look and seen that it did not boot this time so i look and the green light was not flashing so i open the shell etc...i found that the r3b15 wire was off the point it somehow rubbed onto another point beside R3B15
That resistor (STBY_CLK on a Trinity motherboard) is a very small and fragile point which will lift very easily if you are not careful.
You can use FT3N2 underneath the board instead (it isn't surrounded by any small components, so it is easier to work with).
If the original point has already been damaged, you will need to repair it first or the console will not power on.
Look at the image below for it's location (ironically, it has been posted on the se7ensins forum lol).
