Boots into stock boot animation

[YoungBeta]

Hello, I installed this modchip on a 1.0 xbox, and when I power it on, it goes into the stock boot animation. The hard drive and disk drove were not connected. What did I do wrong?

[YoungBeta]

It also stops working after 20 seconds with the disk and hard drive plugged in

[MrKittenK]

Have you grounded D0?

[YoungBeta]

Yes, I have. I put the point under wire 2

[MrKittenK]

I mean is D0 grounded on the motherboard. It's the only other thing needed to do separately.

There are vias and test points available on the upper and underside of the board. Plenty of guides online.

I've linked a pic as example

[YoungBeta]

Thank you so much! I have a 1.0, so where would I put it on ground?

[MrKittenK]

This shows the various points.

I know it's for Installing a different chip, but D0 is D0 💛

I use the easier to solder point on the bottom of the board, keep it short. If you want to swap to a modchip that can control the D0 line at some point then you'll have to unsolder and reattach to the new mod chip, so keep that in mind.

Ok, thank you! I really appreciate your help.

[MrKittenK]

Ok, thank you! I really appreciate your help.

You're very much welcome ✨ Always happy to help. Feel free to drop a message etc if you get stuck at all. I'm not the modXo creator, but I have some Xbox knowledge and love what Shalx has put together

[YoungBeta]

Hello, I ripped off the solder pad, but is there another point I could use?

[YoungBeta]

Alright, so I bought a new board and I'll try again. I'll provide a update when I get it!

For D0 grounding, you can use the motherboard screws, those have contact with ground pads.

[YoungBeta]

Thank you, I didn't know that! Also, how would I replace the trace on the old board? I know to scrape away the remaining trace, but where do I put the jumper to make it function again? I'm relatively new to soldering and the original xbox itself, so I would like to learn more about it. Thank you!

[MrKittenK]

There are alternative D0 spots. I always recommend flux, lots of flux, plus a temperature controlled soldering iron. If not temp controlled, keep to 15w and use 60/40 solder.

I shall reply asap with alternatives. 1.0-1.1 uses one set. 1.2-14 uses another. 1.6 is already explained on the ModXo readme

[YoungBeta]

Thank you! Do I need to fix that trace for the console to boot, or after I ground an alternative point it will fix the FRAG that currently occurs? Again, I appreciate your help so much and you have been very helpful!

[MrKittenK]

I believe the trace will need to be fixed yes. I shall double check.

Most welcome ✨

[YoungBeta]

Alright, I'll try to do that sometime.

[YoungBeta]

Alright, so I got the new board, and everything seemed to be working fine (got new hdd), and when I put it back together, it stopped working, so I bought a new Startech adapter, reflashed the pico with cerbios UDMA5 , and now I get error 21. I even reflashed with the hybrid bios again, but I still get error code 21. I used a different hard drive, and now it just hangs. The error picture is listed.

[YoungBeta]

I fixed it! I only had to change legacy mode to modern mode in the cerbios configuration and use a ssd, and it now boots! Thank you guys so much for your help, and my problem is solved.
