Hello everyone! I will tell you about my problem: I have an Xbox 1.0 with TSOP and 128Mb of RAM (I bought it pre-modified), I have tried to install an Aladdin Xblast by soldering the pinheaders to the LPC port and soldering point D0 of the motherboard to D0 of the chip (I have also tried soldering D0 from motherboard to ground on motherboard) and got FRAG. I have followed Barnito's Lpc Diagnostics (V0.1) guide (https://www.ogxbox.com/forums/index.php?/topic/239-lpc-diagnostics-v01/#comment-945) to verify voltages and continuity. With respect to continuity everything is correct except pin 2 and with respect to voltages everything is correct (+-10% of the correct voltage) except pin 1 0V and pin 5 1.7V. If I disconnect the D0 cable from the chip or ground, or if I disconnect the Aladdin chip, the console boots correctly with the Cerbios bios that I flashed in the TSOP and boots my Xbmc4gamers. What could be the problem? (if photos are necessary, I'll take them later when I get home from work)

I did search first before posting and couldn't find any threads specifically talking about this. I'm sure I'm missing something obvious. I have tested with an original XBOX S Type controller and a 3rd party controller. I have also tested with a USB keyboard and an adapter. None of which work when I enter XeniumOS. However, the controllers work when modchip is disconnected. This is a 1.4 revision XBOX. I assume it must be one of my solder joints to the modchip. I have already reflowed these joints multiple times to fix another issue. Unfortunately, I closed the machine up before I realized the problem. Anyone know which pins I should focus on? Is there a way to test continuity between LPC header pins and the motherboard? Thanks for any help you can provide.
