Personally I haven't heard of any that have failed from that, but I'm still new to Xbox modding. I may see about removing the resistor in the future, but since the console still works and the mod chip works to boot up custom bioses, it isn't a top priority. I thank you and everyone else who commented on this thread for the help I've been given. Sincerely, DobaMuffin

I am sure. I connected it to the Xyclops side of the resistor just like in the diagram. I even tried putting it on either side of the smd pull up resistor that was already on the main board. That made no difference. Thanks, DobaMuffin

I'm guessing that system still has its clock capacitor installed? If that's the case, and if it's a 1.0-1.5, you need to remove it. I see damaged traces in that photo you uploaded. If you repair the damaged traces, the console buttons should work again, but it also seems like there some corrosion at various points on that underside there. You'd want to gently clean that off. I'd say use a soft toothbrush and some isopropyl alcohol to gently clean it up. As for the damaged traces, there are 2 methods to repair it. You can solder a short length of wire across where the breaks in the traces are, or you can solder a wire from the end of the trace where there's a via that goes through the board, and solder the other end of that wire to another via somewhere after the break in the trace. A multimeter is best to help with that too.

By worked like normal, I mean before the mod to the LFrame trace, setting the switch to disable the modchip allowed me to boot up the console stock as if no modchip was installed. After the little hardware mod though where I cut LFrame and then soldered a resistor to reconnect LFrame properly, the board won't boot up with the modchip switch set to disabled. Instead it Frags. But if I remove the D0 wire that's connected to LFrame on the motherboard, the console boots stock properly. The bioses I'm using on the mod chip are xecuter 2 5035, and m8+ 1.6. those work properly though. The D0 wire on the modchip is connected to LFrame on the main board since it's installed in a 1.6. The LFrame trace has been cut, but then I also installed a resistor to repair the LFrame trace so that the mcpx doesn't push too much current and fry itself eventually. As for the warped main board, it was like that when I got it. So I have no clue what happened to it.

Hello, I am writing this today to see about getting some help with my 1.6 Xbox and the Xeceuter 2.6 CE installed in it. I recently did this motherboard mod involving a resistor to extend the life of the board and the board works fine after the install. This is also where I managed to find an issue. With the mod chip enabled, both banks load up their respective bioses, but when I disable the mod chip using the front panel switch, the console Frags after 3 tries. When I disconnect the LFrame wire from the mod chip, the console boots up like normal to the stock dash using the stock bios. Before the mod though, disabling the mod chip using the front panel switch worked liked normal. So now I am a point where I made a modification to extend the life of the console, but lost some functionality in my mod chip at the same time. I am wondering if anybody knows what would cause the issue I described and if anybody else has ever run into similar issues. Though I know most don't tend to mod 1.6 consoles if the can avoid it. I'm also curious if anybody else happens to have an Xbox motherboard that is warped around the CPU and GPU area. By warped, I mean that I can see a curve in the motherboard around that area. Thanks, DobaMuffin

Thanks for that. It sucks that they degrade so much. I guess replacing the flash chip with a new one (huge risk of messing up) or chipping the consoles are the way to go. Though a modchip would be the way to go unless restoring the console to look stock. Though reflashing the chip will still work for a while wont it?

Hello everybody. I recently got to thinking about the data retention of the flash memory used in the original xbox. I purchased an original xbox not to long ago that was basically a coma console in that it would have a green light, but no audio or video. Turns out the bios was corrupted or something similar and that it would boot with extreme difficulties after pressing the eject button a bunch of times until the drive ejected. Basically these symptoms. I did manage to flash a custom bios onto the system and that solved the booting issues it was having, but that then leads me to what I have as a discussion today. Looking at the datasheet for the Winbond W49F020 series of flash memory used in my console, I notice that it has a data retention of 20 years. This means that it should hold the data for about 20 years no problem, but it seems like mine started having issues early. By what I can tell, to refresh this data and basically restart the countdown, I need to reflash the bios to the chip rewriting the data. This brings it back to a state where the data is properly stored and is ready to last another 15-20 years. My only concern about the whole thing is that flashing a new bios can go wrong and cause the console not to boot without a mod chip. My question to someone more knowledgeable than me in this topic is, are we going to see more and more stock consoles fail to boot due to corrupt bioses in the up and coming years? I know that 1.0 and 1.1 consoles already have some issues with their 1mb flash chips, but will all sorts of version have issues? ie, 1.0 - 1.6? Is this just a limitation of anything using flash memory in a component used to boot up? I know nothing lasts forever, but I do try to make it last as long as I can. Thanks for taking the time to read through this and I hope it can spark some good discussion on the topic. Also if anything I have here is incorrect, please let me know as I am still learning about hardware in general, and I try my best to be accurate in my information. DobaMuffin

This would have been lovely to have when my console had a really corrupt bios and would barely boot at all. I only found out stuff like this was possible after the fact and I struggled to get the console to boot so many times to go the tsop flash from softmod route. Hopefully this process, or similar, will come in handy in the future.

Hello, I always end up late to these modding scenes due, but I hope to learn about the original xbox and discover how much fun I can have modding these old things. I do have great memories though. Growing up with an xbox can do that sometimes. Hopefully you enjoy this as much as I do.
