Switch Oled black screen (after clk point short in GND), hwfly infinity training (yellow led blinking.

Paulo_Suzuki · Jun 1, 2023

Hello everybody! I would like help with a problem, yesterday I successfully managed my first cfw on the oled model, I turned it on and I had a hekate screen with micro sd, but when closing everything, unfortunately the nvidia chip shield touched the clk point (d point), after that I only have a black screen with hwfly in "training" mode (infinite yellow led), I measured the clk point and I still have a value of 714 on the diode scale, I tried the sthetix video for unbrick level 1, 2 and 3, but without success, because I can't start hekate, can you give me some advice on this? We can make a payment for your support, thank you very much for your attention!

I won't do unbrick until you see hekate tells you emmc init failed. Try remove all hwfly cable and see if console boots normal into hos.
I've worked on someone's dumb clk point insulation job ( D point touching CPU cover shield). And console still works and even hwfly survives after all cable redo in proper way.

Thanks for your answer! I got the same advice from sthetix, today I finished removing all cables from hwfly, but I still get a black screen (console won't turn on), when I put it on the charger there is no signal.

I will provide a photo of the plate and the clk point.

Have three questions:

Would a possible break in the clk point of the nvidia cpu with the emmc result in a black screen?

Can I get a clk reference point from the emmc to measure continuity with the clk point next to the cpu?

This cmd component near the cpu if it is having problems can result in a black screen? what would be its value?

The CMD resistor often time give people purple screen when the resistor failed due to the long time high heat from solder iron.
Your pic or vid is not clear enough to see if any broken trace or via damaged on the clk through hole you have worked on. But It's likely would be either CLK point or Emmc corrupted by adapter leading the black screen
