I am trying to mod my ps2 v5 US as stated in the title with a modbo 4. I can access the menu, but I can't boot any disc at all, I have tried regular dvd, ps2 game, ps1 game, ps2 cd and burned games and I keep getting a ps2 red error for burned games. I have got the error DVD player is not configured or something like that while trying to boot a regular game. I have used that schematics to mod my ps2, I think that the problem might be cold solder joint which I was extremely careful to avoid, but looking at the schematics, you will notice that there is no H point and I didn't tried to solder that point. May this be the cause of my problems or some cold solder joints are probably the culprit. Also, I can access the modbo menu with no problems at all and I can navigate through it.
I have read this thread before posting, I want to know If I have to solder the H point as the schematic doesn't seem to require that joint to be solder.
"H" needs to be connected. If it's not then it won't boot your PS2 backups/imports. Not quite sure why it's left out of the diagrams.
