Ok, took the mx chip from the fecked ubee, wired it up as I would normally, joined pin's 1, 2, and 9, joined negative of power supply to pin 10 of spi, (Pin 2 of usbjtagnt) both wires then connected to pin 2 of usbjtagnt, then applied 5v usb power (I used a good hub) to the three wires previously mentioned to the + usb power, detected chip, flashed and verified each section, then verified all flash, disconnected programmer, disconnected power, reconnected power, plugged in programmer, got a good read from all section's.. so far so good, now I'm gonna swap out this chip from the good board, finger's crossed..
Update, seems the chip was fine, read and verified with 2 other spare chip's, strangst thing was, when I put chip back on board, pin 1 and 2 were then perm 3.5 volt's.. time for a rework me-think's, if anyone has ever done this, why would this happen?
And eth is still dead, but can read/write from chip. Also I should add, that when connecting power, I noticed one more handy tip.. solder 5v to pin two, then cut wire, shred sheathing enough to twist wire's together, because it seems that when wire is just soldered on, all 5 light's go solid dim blue, but by scrapping the two ends to twist as you would hot wire a car, the lights will change from 5 to 4 or 3, this is your goal to unbrick, or at least, flash chip, successfully, if the 5 lights are solid, chip wont be detected.
