Riff Box can repair dead boot of this phone. I managed to brick two of these phones (both didnt have download mode, so I used Android SDK & both phones died!)

Only problem is it's a very fiddley task trying to solder the wires to the board. I wish someone would bring out a jig!

Are you kidding ?

you just have to brush white paint, and pads are there, don't use the small tinned points of course.

i9000 jtag pads are too easy, regarding to HTC G1

100% tested to me...

since that kind of resistor is not available here

i took 3 pcs of resistors (100K) from any bb5 phones...just connect all the resistors and connect every end to pin 4 and 5....

although it is 300k (not 301k) but it is enough to force in download mode

another alternative is here

Noob question :-)

I have a Micro-B connector cut from a usb cable, which pin must I use?

1 = Red (VCC)
2 = White (Data -)
3 = Green (Data +)

4 = ID (Micro-B not connected)
5 = Black (GND)

So if pin 4 (ID) is not connected, where do I put the resistor?

If I stripped the connector, I see under: black, green and red and top: white and one that is not soldered.

So it is pin 5 (black) with the one that is not soldered?


Sorry for the noob question ;-)
