I tried using a qsb and don't work so i desoldered it so.

Im going to make my own sd rw for the 4gb corona v2 .

Here is a pic of pin layout.

Can I use a different ohm resistor? Or dos it have to be 68 Ohms?

I would just get the 68 ohm res. They are pretty common and can be found at an electrical supply store.
If u can't find one pm me and Im sure I have one I can mail you.

Rats I lifted one of the pads, do you no if theres somewhere else I could solder the green wire too?
If You Rip It From The Motherboard Your Gonna Have To Fix It, If It Isn't Repair Then Your Console Won't Work.

you can carefully try it. i would get some thinner wire though like some 30awg kynar wire. you will need to bridge a jumper accross the two vias where your upper arrow is because you broke that connection to the nand chip thats underneath the board.

Update N Newsk I tried the wire method, problem is when I tried soldering the sd reader cable to the jumped 30 gauge wire , the wire just desoldered from the points :frown:.

I have also tried using copper tape but it just lifted of as well .

U will need to scrape aways the pcb coating and get down to the copper trace/via and get the points pre tined first .
