My jasper console gives me no signal on monitor, doesn't boot into xell after writing the ECC, It just flashes green lights.
One thing I messed up on is not saving the original NAND.
I did all the wiring correct, I made sure the Diode is on the right way, And I am using a 22k Resistor.

Things I Tried:
- Tried no resistor
- Tried no Diode
- Tried 10K Resistor
- Tried flipping Diode
- Tried new Diode
- Tried ALT SMC_PLL
- Plugged in DiskDrive (Same issue just instead of flashing green it was solid green no signal)
- Tried clicking eject instead of power
- Re-did all the wiring with new wires, new resistors, new diode

My Setup:
PLL -> Resistor -> ALT SMC_PLL (Also Tried SMC_PLL on other side of board)
POST1 -> Diode 1N4148 -> SMC_POST1 (Black tip is on POST1 Side)

Wiring (Pictures):
**(I don't have the wires taped on the board yet since I'm just trying to get it to boot into xell, so I know the wires are not interfering with anything)**

POST1 Point:

SMC_POST1 Point:

ALT SMC_PLL Point:

PLL Point:

Other Notes:
- I did test the console before I took it apart, was working perfect, usually before I open up the console I test everything and then format the HDD.
- I did use flux
- HDMI & Power cable indeed work because before I took it apart its the same one I used to format the HDD.


So without the original NAND dump I'm not sure what I could do or try, and I'm not sure how to make a NAND either, I just recently got into the RGH3 scene.
I'm pretty new to this, but I have done lots of research before going ahead and starting everything.
So far I have done 4 Trinity motherboards right off the bat but I'm not quite sure what went wrong with this jasper as you can see my wiring looks good.(I think)

If anyone has any suggestions or knows the issue I would be grateful for any help. Thank you.

I think it basically comes down to the fact that rgh3 is unstable on phats. Pretty much everything you have posted looks right from my memory. The solder could use a little touching up but it should work. If you have a chip i would recommend trying rgh1.2 as it is stable and was designed on phats. As for what to do about the nand, check our my tutorial here on how to make a donor nand. You can extract the kv from your currently modified nand to make a retail one again.

rgh 1.2 is absolutely perfect on phats not sure why anyone wants to improve single glitch boots. not sure i get it. rgh3 is for slims imop. And theres never an excuse to loose your original nand. Think of how stressed backing up your nand dumps have been from the begining of jtag etc.

Jaspers are pigs for RGH3, they can be done but not without challenges.

I know this post is outdated but wanted to ask if you found a solution, I was RGH'ing my kids' falcon system and am experiencing exactly the same issue

I just did 2 jaspers and now on my third ripped pll pad, did the under heat sink under solder mask and got into xell once... redid all soldering no luck flashing green. I can restore og nand to get rrod so I am assuming the console is fine just I guess i hit the RGH3 wall?
