420 Missing TDO Solder point ?

[indal_98]

I have a 420 in front of me,went to do the zkt mod and there is no solder pad for the TDO only a pinhole but manage to get the jtag wire in but jkeys couldn`t detect so I flip the board over and again no solder pad tried the wire in the pinhole but no detect, My JTAG IS GOOD anyone else have this problem or know where else I could solder the TDO too. I don`t think I can use the solder pads to the left of the normal pads can I ? any help would be great.

You need to get the IRD in BFL (Boot From Link) mode so you can gain control of the chip. Then if you look at the board from the back, there will be 2 rows of through holes, the left row is for JTAG, the right row is all ground. The pinout are clearly marked right next to it (TDO,TCK,TRST,etc....).
