Hi everyone!

Im really hoping someone here can help me. Basically, I plugged in my SGS2 via USB and thats when the issues started. Windows 7 told me the device was not recognized etc. The phone thought it was charging when it wasn't even plugged in and I got to messages about overvoltage issues whilst unplugged on a ICS ROM.

After much research I found out that its not the cables, drivers etc (as iv tried various PCs, OSs and cables, but that its actually the usb connector on the phone side.

So, today i went and bought rubbing alcohol and compressed air, used them and my USB issue is fixed. it read perfectly now, no issues. There was a lot of dirt in the socket!

But, just in case the phone does it again, I have warranty. But, not if my Binary Counter shows 100+ flashes. So I will be making myself a USB Jig after college today. I have purchased resistors already. I got 3 X 100Kohm resistors (I was assured they were right). They are blue and have the following bands: BROWN - BLACK - BLACK - ORANGE - BROWN.

As far as I can work out they are correct? Please could someone double check this if they have Jig experience? I will be using a spare nokia Micro USB B cable to make the Jig.

If anyone could calm my nerves that would be great!

I will stop typing now... haha

Orange? Sadly whoever you bought it from is mistaken. Color band should be Brown-Black-Yellow-(XXX). (XXX) can be different according to the tolerance, but brown is fine. The color you said is a 10K resistor, not 100K ohm resistor.

Thanks for the replies,

@Kaze105, according to an online resistor calculator its 100K ohm so Im very confused. whenever I look at tutorials, thier resistors are always different looking to what I get over the counter here in South Africa. Its wierd, but more so annoying.

Well sorry for my error, didnt see it was a 5 color resistor (lol), you are correct if its a 5 band, my thinking was as a 4 color resistor.
