#N900

Also it didn't make all that good contact with the "pins" (just ends of wires...) that were not exactly same lenght...

Need to rethink my approach, either find very small springs or hook the phone via bench-supply and use blue-tack or similar to get wires on the pads with the battery out of the way.

Are you doing jtag-debugging or something similar?

Actually I'm trying to find out which pads are which, JTAG is there somewhere but doesn't interest me much ATM, serial console TX pin was located by another guy and I'm mainly interested in finding out if the I2C bus can be accessed via those pads (which would allow adding all kinds of interesting sensors with relatively little HW hacking [compared to opening the case and soldering wires to SMD IC feet...])

Unfortunately the phone takes on boot more current than my puny lab supply can give, OTOH #hacklabfi has not only better supplies but better scopes and better logic analyzer (though I don't know yet how to use it, the one in the background of the image is Open Logic Sniffer)
