I think this is bsi track 100% missing.When you removed capacitor then bsi track destryed.Becouse without bsi dc power supply show 1 or 2 after then 0.So you need bsi jumper.If you need any help call me :008801922661249.I am in bangladesh.

He he good coment.................If you want good hadware you must have good idea about dc power supply reading.When you want to power on 3100 with dc power supply, connect dc power supply (+) with 3100 battery connector(+) & connect dc power supply (-)with 3100 battery connector (-) & bsi togather i mean gnd & bsi must be short. Now press power button phone must be power on(if phone is running).Now disconect bsi from gnd & press power button phone can't power dc power supply show only 1 after 1 or 2 second 0.Now Red com will find his own way.He can take help from schemetics otherwise he will take another 3100 board & findout bsi track by multimetere.
