Issue not solved. possibly I broke it with a wrong pinout or connecting the chip with the tsop-clip. I wrote the NAND successfully, both banks, right size, with external power 3.3 volt to the NAND. Still a solid red light.
I'm looking for a diagram of the mainbord to see if I can power it on with an alternative path than the poweron button.
Hi Johannus,
You seem to be having the same problem as me, I successfully flashed my backup, made before CFW. I reassembled my unit and it came on but said it optical drive was not connected, so once I connected it jjsut stayedon the loading screen with out an error code.
So I attemped to reflash it but would not connect properly anymore, kept giving errors when attempting to write.
I went ahead anyways and after numberous attempts the board would not display a blue light just solid red light.
I am think that due to all the fiddling around I damaged something cause when I move the mainboard I do hear a light creaking /click as if a solder joint is loose. I think it is on a nand chip cause some times depending on how I position the board I do get a reaction from the connected teensy.
What I would love to know is when testing what devices need to be connected, for example will the wiiu power up if any of the network chips are removed?
or if the heat sink is removed. in order to get access to the pins I needed I removed the heat sink and tried flashing it without putting the heat sink back and just used a small 12v powered fan.
Now my board just shows a solid light ,nothing after pressing power,no video output teensy sometimes sees the chip but trying to write gives sector errors.
Also if you find a way to fix your problem please let me know.
I hope someone finds an easier way to try and bring these systems back from the dead.
