I am looking into it. I have a ST model TSOP, so I guess I need to bridge the two points on the top side of the motherboard (1.4). How should I go on about this? Can I do it without solder (just soldering iron)?

Okay so here's what I've done: I repurposed the old 8GB Xbox HDD (had it upgraded to a 160 GB) and removed the softmods and basically made it retail. I cleaned the LPC port, applied new solder to the needed points and soldered the modchip again, connected D0 wire to alternative point, and surprise surprise, doesn't work/show EvoX. Doesn't boot burned games (the discs work, as I can confirm they did when it was softmodded) or my out of region discs. D0 wire disconnected, same thing. It really is dead, huh?

I've tried both methods, but the chip doesn't seem to be working. In fact, I experienced some weird glitches, the screen "shakes" occasionally and I've decided to remove it completely. Been working fine since then, played San Andreas for a couple hours and no issue. I guess I'll just give up on the modchip, spent too much time on it haha. Apparently BIOS checker was false, as when using a Hexen disc to try and flash the modchip, the BIOS information reported that it's a stock Xbox BIOS and cannot be flashed. I guess BIOS checker reports the modchip status because I edited the EEPROM region from NTSC-J to NTSC, because some games showed japanese text no matter what I did. It is softmodded. I used hotswap method to install Rocky5's softmod. The reason why I want to get the modchip working, is that the DVD drive on the 1.6 Xbox is dead so If I were to get it working, I'd have to flash a nodvd BIOS (either on TSOP or Modchip, so modchip in my case) to get them both working. I'm really hoping I didn't accidentally killed the 1.6b motherboard.

Yes to all. Seems like this chip really is dead. I don't mind, though. Tried everything over the last few days, and it seems that it's no dice. Rip. Anyway, I wanted to ask. This other Xbox I have, it's a 1.6B model. I swapped the motherboard into a 1.4 case (I know, bad idea, had no clue unfortunately). However, the powersupply was the 1.4 powersupply, so it didn't power on. Is there a chance it's still alive? It's an NTSC Xbox so I'll need a transformer to use the 1.6 powersupply. My country is in full lockdown atm so I'll need to wait for 7 days to test. Just need a glimpse of hope, haha.

Yoo, I FTP'd Xbox BIOS checker to my Xbox. Ran it, and got this https://imgur.com/EOMWNYs What does this mean? Is the modchip working? I just don't see evoX on bootup.

Resoldering the chip solder joints, swapping linked BT to the modchip, exactly like this guy here https://imgur.com/gallery/n84343r Xbox still boots normally, without evo-x or modchip light. I think this modchip is dead, should I just remove it (or just keep it there) and give up on it?

All looks good to me. I have an idea. If I remove the two wires L1 and BT and connect BT to the modchip as you said, would that help? Also do I need to desolder or can I just cut the wires (L1 and BT) and reconnect BT to the modchip itself. Just for time saving measures and me not comfortable with desoldering on the motherboard itself (LPC is fine tho).

I actually caught that around a month ago before it leaked and cleaned off the board with ISA both top and underneath, here's an updated picture https://imgur.com/2QmuHND I recall inspecting the underneath of the motherboard and it's more than fine, atleast where the clock capacitor was. The motherboard is working okay.

Update: Removing the D0 wire from the modchip disabled the power button, xbox turns on with it but pressing it again won't shut it off or do anything. Putting it back in and everything's back to normal, without the modchip working ofcourse. Do I have a dead modchip?

No, it was preinstalled on the 1.4 motherboard I didn't touch it. How should I go on about this? I've read the manual for the Aladdin modchip and it's wired exactly the same. Would that help? Also what fitting? Sorry I've never done this before, but I do have a soldering iron that I used to install a XenoGC modchip on a gamecube.

Hello. I posted about this a while back on Reddit but eventually I gave up and softmodded instead. However, it's kinda ... what's the word for it... irritating to have a non-working modchip as I want to have a backup plan incase my DVD Drive fails, or the other NTSC Xbox that I unintentionally potentially killed by swapping its 1.6b Board into a translucent 1.4 case and 1.4 power supply (EU 230V)... (yeah not proud of that) comes to life. I have no way of confirming if it still works as I have no step down voltage converter, BUT if it does, it'll have no DVD Drive. The plan is, I want to get this modchip working first, if possible. I've tried resoldering the wires, the modchip itself, and it won't work. No evo logo, nothing. All it does is play original games. Motherboard is a 1.4 according to UnleashX. Here's a picture: https://imgur.com/1MME9Nc Is it dead? I assume it used to work before, as it was installed when I received the console (got it for really cheap, had error 7, swapped dvd drive and it works). Is anything looking out of the ordinary?
