Earlier this year, known scene member and exploit creator "Grimdoomer" released the BadUpdate hypervisor exploit for the Xbox 360, while also revealing his retirement from console hacking. It looks like he couldn't stay away from digging into how the 360 ticks, however, because Grimdoomer is back, and has a massive announcement: there's an Xbox 360 softmod method on the horizon. In the past, Grimdoomer himself has claimed that there would never be anything more elaborate than the proof-of-concept hypervisor exploit, but he's one-upped himself, with a video that teases a 360 softmod method.

There is no ETA on any release, and Grimdoomer explains that the process will take time.

I know I said I retired from console hacking but I got one more in me. An Xbox 360 softmod is coming, no eta yet, THIS WILL TAKE TIME to finish. I still can't believe this exploit chain works, and I also can't believe I spent 20 hours a day for the last 3 weeks straight working on this. I'm so tired but seeing that coffee cup on screen was worth it

I have an OG hackable old model Switch, I really should hack it one of these days.

If you really have a OG v1 unpatched, it’s a USB-C, a computer, a sd card and a hour of your time (maybe less depending of the configuration you choose) and then you are done.

That's it? Wow. although should check what firmware it is at.

Doesn’t matter, all fw up to date have cfw

What a remarkable achievement.

Slick to hear he's back to modding, although now I guess I should see if I can finally fix my two RRoD systems ~_~

Not sure why modding/hacking an Xbox 360 is relevant in 2025.... seems like its been done a long time ago...would be nice to see something for the Xbox One S & X as there's currently not much for those consoles and they are more up to date.

I presume this isn't connected to BadUpdate 1.2, which means it is even better, which is FANTASTIC news!!

The Xbox 360 is my favorite console of all time, so it is awesome that this finally happening .

 

[balemoc]

...softmod? Sayless. I'll be Googling how, in 2-years afyer everything is ironed out, ha

Too much backlog (non-XBox Games) to look into 360 (I have the few games I like on discs, and I still havent played them)

 

[CoolMe]

They did release an update as recently as June 2025, which is nuts

the 360? it was literally the same old 17559 fw ver they just changed the dash to advertise the xsxs/x consoles, hoping to entice the ol player base still stuck on the 360 to upgrade and get the current gen concoles, dassit!

Really interesting comeback! The 360 has such a passionate scene, and seeing an “unretired” dev return to push the boundaries again is exciting for enthusiasts.

Also fixed a bug where game images were the wrong aspect ratio (a bug they introduced with the update prior)

I would've freaked out about this 10 years ago.

I've been using BadUpdate 1.2 and sometimes it takes literal SECONDS to trigger. It's so good.

Excited for the softmod, I hope it allows us to use any HDD/SSD.

2nd gen hypervisor exploits might prove useful for poking at the proverbial bigger bear... XB1/Series hypervisor. Maybe those who missed Collateral Damage exploit, will get a second chance.

I believe the exploit outlined here is hope for the crowd who do not dabble in hardware exploits that require technical skills like soldering.

and this is a SOFTmod

if you can't grasp that concept, log out permanently

If you can’t grasp the concept of simply hacking the xbox360 “Disc Drive” then I suggest log out… permanently

There’s no soldering involved all you need is a copy of the iXtreme lt+3.0 a laptop, jungleflasher, CK3i and a probe for the “Disc Drive” to extract the bios file and a special tool to unlock the xbox360 which is cheap as chips that’s it

Here you go these are the tools you need in the photo. I’m sure if you go on AliExpress you can probably buy them all very cheap now

I will admit you do need a special disc drive and an xboxusbpro tool and the exploit file to be able to burn the games at over the 8GB capacity and you need to buy verbatim dual-layer discs but it’s worth the trouble

Edit: before anyone asks I do not provide any sort of hacking service I never have done. I’m completely legit these are only old personal hacking memories

... 'like' being keyword. Console disassembly and motherboard probing, I would still consider technical skills. I'm sure someone of your caliber would be surprised to know there's many would-be backyard unethical hackers that haven't opened a console ever, let alone use probe tools but I digress... the just of my previous reply was to merely state that there's hope for the many looking for less technical solutions for their Xbox 360.
