I wish there was an active OG Xbox community on Lemmy. The subreddit helped me get through my journey of doing a hardmod (TSOP flash) on my 1.0 version; I had an unfortunate disk drive failure at the EXACT wrong time (after the softmod), and it made things a LOT more complicated lol. But I also learned wayyy more than I anticipated, and have flashed 3 more since then without any issue (except for finding a roach infestation inside one of the cases, but I still salvaged the hardware and flashed it)
But regardless, you can message me too with any questions. I’ve never installed a chip to hardmod, but I can TSOP flash the hell outta them now. And if you’re able to hardmod, I highly suggest it mainly because of how much more stable it becomes
Edit: This wiki also has pretty much anything you’d want to know about modding the Xbox https://consolemods.org/wiki/Xbox:Original_Xbox_Mods_Wiki
The softmod is pretty easy, especially if you have one of the exploitable games lying around (I had Splinter Cell). The flash drive-to-controller port converter-cable and a compatible flash drive (listed on that website) is all you need.
Just write down your EEPROM number after you softmod, for the love of god, even before trying to zero it or back-it up. That was when mine froze, restarted and the disk drive failed, giving me an “error code 7”… which not many people knew could be due to a dead disk drive, because it can be due to several things. A TSOP flash (if you have a version earlier than 1.6) allows you to run without a disk drive, and an unlocked HDD. It makes it pretty much brick-proof
I had no soldering skills when I tried it, so I was very intimidated too. But a $15 RadioShack soldering iron got the job done… the TSOP flash technically only has to work once. I even “lifted the pad” on my second xbox, but there are alternate points you can use a jumper wire on, if you fuck up the first attempt. .
For a $30 xbox at a thrift store, it might be worth your time to try. I say this from the other end of doing it, but it was also my first mod, first soldering job, and I was terrified I would fuck it up. Turned out, the soldering was the least of my problems after my disk drive failed lol
But either way, good luck! It was one of my favorite projects and is still in use as a balling emulator. The thing has a lot of potential once you get into it!
