Bricked my 1st SB6121

[random4102]

Yeah that's cool but I have a ribbon method which provides a quick access to the jtag w/o having to open the case each time. My question was about the procedure for reading & writing? If I already have known ISP point then I don't have to do external power correct?

Is the R153 100% confirmed ISP for the SB6121?

Can anyone please confirm R153?
I have searched everywhere and I am getting so many mixed answers its ridiculous!
When I do it, for the first time! I'm not trying to brick mine

Picture I had laying around, not sure where I found it. Another way too via external power via usb

Best of luck to you

Everywhere I read I see people saying "just do it as you would a 6120"
and I am 1000% that the ISP on 6120 is on the back of the board closest pin to R362 R358. Now if the boards are the "same" and labeled the same, then it'll work..Thats the next thing to find out.. Let me know if you have any luck
