Headunit Firmware Dump?

[nanaisu]

Hi all,
apologies if this is posted in the wrong place, I'm more of a lurker than a poster. I've been reading up on a few threads related to coding and was wondering if anyone had dumped the firmware and or filesystem of the headunit for the Supra.
I'm more used to REing malware and not headunit firmware or car hacking in generally... but I'd love to give it a shot if it's already been dumped (or if someone has general instructions that may apply to the Supra.)
TIA

Apologize to revive a old thread/post, But have you found any dumps? im in the process of RE it and finding a way to change the seatbelt / warning gong/sound to custom Audio.

Thank you

With all of these advancements in AI & things like the bar behind reverse engineering dropping, it would be awesome if someone with more knowledge/capability would be able to use AI to decompile the firmware and safely modify it to enable us to do fancy things to our cars.

With using AI for reversing, one of the key things you need to remember is that you need to be able to fact check it's work, or you pose the risk of breaking something that you might not be able to recover from.

The biggest capability I want at the moment is being able to code start/stop off by default.

Can't this be done with xHP?

Pushing a button too hard

Pushing a button too hard

No, but it's a design flaw that can (still?) be easily rectified with Bimmercode in seconds. And once you code the car to start in Sport mode, that's two buttons that won't bother you ever again. And when you code auto locking when you walk away, that's three.

If you can fix these little annoyances, why wouldn't you?

Maybe because I don't see them as annoyances just part of the driving engagement. I spent 42 years in aviation and there's a checklist for everything, pre flight before start, taxi check list the list goes on and they all have things to set and check. A pilot might fly 4 legs in a day all on different planes as well so there's a lot of buttons and stuff to move and check. Pushing a couple of buttons is nothing to me in all my cars. The Supra has 2 the Kia has 3 to push and the Mazda has one. No big deal as far as I'm concerned. Half the conversations here are about having to reset the coding again after it's reverted back anyway.

The only way it reverts back is if the dealer runs a particular update on your car.. and generally speaking, most Bimmercoding usually persists. As a clear example, I have never had to re-code start/stop once I disabled it a few years ago, even after the dealer replaced my instrument cluster and ran relevant updates. My coding even survived the Femto unlock.

Also, I'm not sure I jive with the idea that superfluous button presses are cool. I'm sure every pilot alive will tell you that reducing the checklist is a good thing.. when said checklist contains items that have zero bearing on the safety or normal operation of the plane.

Bimmercoding out annoyances and poor design choices improves this car immensely in my opinion and is easily one of the cheapest and best modifications we have at our disposal.

Ok, so I might damn well have the first Supra running Android Auto natively.

It cost me about $500 in tokens, and there's still work to be done.
I will open source the code when its done. I obviously need to work on the resolution, but this is 100% natively running on the NBT Head Unit. There is No MMI unit. I'm connected directly to the CarPlay wireless network.

There's a few quirks I/GPT-5.5 need to work out...
- Resolution
- Audio Streaming
- Controls/Touch Screen
- Launching natively within iDrive
- Coming up with a free way to open SSH on y'alls head units

Once again, I will not charge for this like bimmer_manufaktur is planning to. I cannot guarantee compatibility or anything of the sort, however, I'm happy to have AI look at it and hopefully come up with something for you. Once it's finished, I'd obviously like to recoup a bit of the cost, so I will include my PayPal, but for now... I've got some vibe coding to do.

Ok adrenaline rush is over, have a picture

Amazing job man, this is something that will meaningfully change a lot of driver's experience with the Supra. Will throw some money to support you once you post the PayPal link and I dont even use an Android.

This is some impressive work,

Can I Help? I am being serious have knowledge into low-level and I am a Computer Science, Cyber security. And Also I'd like to add a couple of features some people would also like like changing the chime to custom bring your own audio, and changing the pictures of the black supra to custom colored Supras. I have a designer friend that can also help with this. and see many other things if people would like.

Obviously im only doing this for the love of the game. All donations can go to you I don't want any

changing the pictures of the black supra to custom colored Supras

has already been done before
https://www.supramkv.com/threads/guide-custom-supra-icons-throughtout-idrive.24478/

@a90.faz had all the UI assets posted on GitHub
https://github.com/FarazzShaikh/j29-supra-id6-assets

And here's all the audio:
https://github.com/Sq00ky/Supra-Headunit-RE/tree/main/audio
90% sure there's checksums in place for audio. I've tried, and I know others have and haven't had luck.

Code currently exists here: https://github.com/Sq00ky/Supra-iDrive6-Android-Auto/tree/main/Milestone-2
