I posted on this subject before and have a few more questions. I have a V4 NTSC with a Neo Key USB and a No-solder mod. I would like to give this unit to friends little boy but I am having some problems and would like to fix it first.
I am able to boot all originals fine. The Neo Key/Gameshark boot PS2 CD-R backups flawlessly. The no-solder/Gameshark booted DVD-R flawlessly for about a month. Now it only boots DVD-R 1 out of every 10-15 tries no matter whether it is lying flat or standing up. I can tell when it will boot the DVD-R because 10 seconds after my swap with DMC (which is not nicked or scratched) there is no sounds from the laser. When it doesn't boot it will start to make a ticking/spinning noise 10-15 seconds after DMC swap. If I continue, it will freeze at the "updating codes screen". I tried it with the lid off the PS2 to see what was happening and I noticed when it froze at the updating codes screen the (backup) disc would stop spinning. I don't think it's my laser as it boots CD-R with Neo Key flawlessly. The no-solder did work fine for about a month.
I would really like to have it fixed so I can give it as a Christmas present. Any help is appreciated!!
