    I found a really old Xbox 360 xenon model brand new on ebay with kernel 2.0.1888 on it
    This is the first public kernel version and I dont want to update it.
    As I am a noob in the xbox scene, I was wondering what can I do with this one?

    Dual NAND system possible?

    you can jtag it, but that's gotta be a xenon. I don't know how long it will last.

    Sounds fishy.
    I assume it's sealed in box?

    1888 is useless tbf, the 360 had a day 1 update that bumped the kernel to 2xxx.
    I suppose updating it to anything under 7371 would make sense if you want to JTAG it.

    Dumping the NAND and removing the resistor that blows the efuses allows you to keep 1888 on a dual nand if you'd wish.

    I say don't invest too much into it. it's a ticking time bomb. xenons are notorious for failures. I only beat one or two games. Braid was one of them before mine kicked the bucket.

    A system like this would be best utilized by a developer for reverse engineering and penetration testing. For an end user, it’s not really useful other than rarity value. Plus I’d imagine they’re asking a high price for it.

    1888 can run kk exploit via updating to 4532, or just update to 4532 and jtag, dual nand is only possible with rgh

    does the king kong exploit work on that low of firmware? I know it's the only software style full exploit, but it was patched at some point.

    KK exploit should work on whatever kernel King Kong required until 4548.

    Dual NAND is possible on JTAG.

    Kk exploit works on 4532 and 4548 iirc, 4552 - 7371 is jtag only, the exploit that makes kk and jtag work was introduced when 4532 was released, as it updated 2bl (CB) and blew fuses, 4552 patched loading kk exploit and blew fuses to prevent downgrade back to pre 4552 (without CPU key from kk exploit) dashboard, they patched kk entry point, but didn't update or patch the syscall exploit itself (a bug within 2bl/cb) until after 7371, which fuses were blown and 2bl was updated, jtag is just the kk exploit but refined and is able to gain execution at boot

    Dual nand used to be rgh only, things might have changed, dual nand isn't necessary if you use online stealth imho

    Also with kk exploit you still need a flashed DVD drive or xk3y

    As others mentioned then being a xenon means there is always a considerable "will this be the day" hanging over it, and it might sound like a plane as well. DVD modding might be tricky but I am not sure offhand what will likely be in it.

    Rather than hacking it you would probably have more luck finding someone that enjoyed the blades dashboard and going with that.

    idvd modding a xenon isn't too bad. I had a hitachi 78fk in mine. iirc, you have to put it in diagnostic or debug mode to flash it, but it's not that hard to do.

    I almost sold one of my jtags to joonie of team rebug. He didn't want a falcon, jasper or newer.

    Dual NAND was never RGH only.

    Cyngos360 or 360 Cyngos, whatever the name of the chip was around well before RGH was discovered.

    Never know with xenons. Some last years; some last months. I'd sell it and get a slim.

    run stock blades, and have a rebooter nand on latest dash...? since xell is needed to use a rebooter to load a later dash, you cant update jtag past 7371, (i think 6717 was the last blades dash)

    with rgh you can keep one nand on the latest dash, and have a separate glitch nand to boot rgh/xell like an emunand of sorts

    My jtag is on the latest dash. Isn't that something like 17559?

    It isn't a stock dash, it has been patched, it contains modified bootloaders, hyper visor, and it boots using a rebooter (freeboot), and a modified smc which preforms the jtag exploit

    Console boots, exploit, freeboot,dashboard

    Freeboot allow you to run a newer dash on old fuse sets (low ldv)

    I know. I thought you were saying that a jtag couldn't be updated past 7371.

    I was referring to the dual nand, it wouldn't make sense on a JTAG, since if its a xenon or zephyr you can JTAG and run any dash between 4532 And 7371 since you'll have your CPU key, otherwise to play any games made after 2009, you'll have to run the latest dash via a rebooter,

    you can dual nand a jtag, you can only run a stock 4532-7371 nand if you have your CPU key (note you have update and dump nand for each version you want)
