GENERAL strange trinity nand

[simlol]

hello everyone.
i got today trinity(not opened before),and start the rgh procedure.
solder the nand wires and when i read the nand via nand-x,j-runner say to me:
Version: 03

Flash Config: 0x00000000
Can not Continue

so i decide to check the nand-x with another console and nand-x work great,i have high level in soldering and that is not the problem.
i follow this:
http://www.team-xecuter.com/forums/showthread.php?t=77908

and check myself with strange value:
1(black): 0.02v,1.42k
2(brown): 0.20v
3(red): 0.33v
4(orange): 41.20 ohm
5(green):3v

what can be a problem?..a manufactor problem maybe?
i done like a 100 trinity with rgh and this is my first time with this problem.
thank you.

It's actually quite common. There's either a cold solder joint under the southbridge or the SPI portion of it is faulty.

I suggest reflowing the southbridge first and if that doesn't help, reballing or replacing it should sort it.

wow...strange case :facepalm:
o.k thank you martin i will do reflow hope it solve the problem.
somthing else: the console boot up.
it's should boot up when is a cold solder in sounthbrigde?..or maybe these points is just an outout points without any effect?..

The console under normal operation has no need to use these points as they are there for dev/jtag reasons. So yes, it's perfectly possible to have the SPI not make contact and the console still work.

Sometimes, it's not the soldering or the motherboard (though it might be with your readings on the meter), rather it's the connector the goes into the nand-x not making proper contect

I've found that pulling out the connector and pushing it back in with a little force results in finding the flash config again.
