Title: USB reset pad
Post by: J on 12. Aug 2009, 17:01
Hi I'm new in modding BT boxes, I want to mod my VIP1216. I have read throught everything here but I can't find USB reset pad on VIP1216, haven't got a clue where it is or how can I find it can you help me please? (I guess modchip won't work without it right)

The modchip will work without it, except if the box resets itself (software) the chip would not get a signal to patch the bootloader.

I used the usb reset pad, because it was the only place I knew on the bt box where a reset signal was output. Maybe there is another chip on your box that gets a reset signal? If so, you can use that instead.

Oki thanks  :) I didn't know that modchip works without usb reset pad. It shouldn't be problem now to install modchip. Hope I don't screw it up.

I don't want to start a new topic so I'll write it to this old one. When I was preparing to install the modchip I noticed that some rezistors around JTAG are missing. Here is picture.

I have read something here on forum about missing rezistors, but it was on some other box so I want to ask if you got some ideas how to get JTAG work what should I use there how can I figure out what rezistors should be there. Box version is VIP1216E I tried to look after older versions but no luck this version was manufactured since October 2007 so I don't think I can find an older box.

The resistors will probably be 10k pullup/ pulldown resistors. You could just wire normal ones direct to the jtag points then to 3v for the pullup ones, and wire the others direct to the pads, then to gnd for the pull down ones.
