I have successfully installed AIO tweaks (plus ID7 Autorun & Recovery) on my 2017 CX-5 with firmware v59.00.446. If I get the CarPlay retrofit upgrade, will any of my installed tweaks still work or will it completely overwrite everything?

If the dealer installs your CarPlay retrofit kit, he has to install the latest FW 70.00.352 (or .335) and this will overwrite any tweak (including ID7). The installation of tweaks via USB then is not possible any more. Except if you do the serial access and install the FW again (see www.mazdatweaks.com/id7).

If you do the retrofit installation by yourself, you can decide to update to FW 70.00.100 before installing hub/cables. With this version you can still install tweaks via USB, as you installed ID7 tweak from AIO already, which works up to/including 70.00.100.

Double post from the AIO thread, if this upsets anybody or is against the rules, I'm sorry and can delete this post. I'm just trying to get as much feedback/information as I can so I don't ruin the CMU on my car. I've done a bunch of googling and trying to find videos on YouTube, but there aren't that many videos in English, and none that really highlights my scenario to my knowledge.

"Hello everybody! New to this forum as I've never been brave enough or had any care to mod my car. My last car was a 2011 Mazda3 i Sport, today I just bought a 2016 Mazda3 i GT and am loving it. I did check the CMU version on it and remember it being fairly low, in the 50's for sure (I can confirm the exact version later today), definitely somewhere between 55 and 59 though. Anyways, I've been doing a lot of research on tweaks and stuff with updating and am liking the idea of being able to customize the infotainment system.

I want to install tweaks, but my biggest concern with doing this is that I have plans in the future to get the dealer-installed CarPlay (I'd do it myself but I don't trust myself to do it without messing up the wiring or trim somehow lol). Is there a certain order of operations that I should do in terms of installing tweaks, updating, etc. to prepare myself in a way where the dealer won't screw me over in terms of having tweaks? A better way to word that, will I be able to have tweaks at the same time as the dealer-installed CarPlay, will I need to install tweaks beforehand or something that allows me to install them after the CarPlay install? I'm aware that once I hit the higher versions, I'll lose USB access. I'm just unsure of the order I need to do things to make sure that I'll at least still be able to have serial access after the dealer installs CarPlay. Also, when I'm restricted to using serial access to install tweaks, is this something I have to do every time I start my car or is this a one time deal, I guess the same question applies to USB access as I'll be using that until I get CarPlay installed.

I really love the work you guys have put into this and really appreciate the continued dedication to it! Thank you! Honestly, I feel like I could ask a million questions about this and don't know if I'd be able to do it all through typing hahaha."

EDIT: Solved, thanks to the help of @Tristan-cx5, I'm fully set up with ID7 and USB access for tweaks at 70.00.100, decided to go ahead with the retrofit myself. I know it's not a huge feat, but it's a big deal to me as I just got the car and didn't want to ruin the CMU. Thank you for all of your help!!

Hi everyone,
Recently a new version of he infotainment system FW v70.00.335-C NA was found to have as part of its update process a highly unnecessary, destructive little script called "neutralizeid7" which DIRECTLY TARGETS ITS USERS BY PREFORMING THE UNDESIRABLE ACTION OF REMOVING THE RECOVERY THAT WE USE TO KEEP OUR SYSTEMS OPEN, CUSTOMIZEABLE AND WELL... OURS!!! This incredibly destructive script once again acts kind of like ransomware without the ransom and it wipes out all the recovery files, not that they would work after the update anyways for even the mechanism that would run those files during system boot time is also removed, and just locks you out so completely even connecting to the serial port will no longer work. As of right now, this new FW is only available online for NA region AFAIK and I haven't heard of anyone being updated to it by their dealership yet so even though I am extremely busy these days I took the time to think about how to stay one step ahead and I rewrote the recovery scripts so that the update will think it removed the recovery but really the new recovery slips them right back in there and will even add the required lines of code back to certain files to make the whole thing work again. Early awareness of all this will help minimize the amount of users that loose access to their systems but THIS WILL ONLY WORK IF YOU INSTALL IT BEFORE UPDATING, IF YOU UPDATE TO V70.00.335+ WITHOUT THIS RECOVERY INSTALLED THERE IS NO CHANCE OF EVER TWEAKING YOUR SYSTEM AGAIN, SERIAL CONNECTION WILL NOT EVEN WORK ANYMORE!

So here is the new ID7_V2 recovery but I need a brave soul to test one thing about it. Insofar as the main functionality of these scripts which is to run the tweaks installer for FW v59.00.502+ it works perfectly and exactly the same as the previous id7 recovery. Also, updating to any FW below v70.00.335 will also work as expected but updating to v70.00.335 is right now untested and that is the part I need someone to confirm for me.
So just to reiterate if you want to install this go ahead, it is safe and works exactly like the old version but unless you are that brave tester I am seeking I would wait to update to v70.00.335+ until the test is confirmed. I will update this post after that happens. UPDATE: ID7 Recovery v2
Happy Hacking My Friends,

How do you verify you hace instaled correctly the ID7 recovery?

Tengo un cx-5 2016 en México con fw 70.00.335, intento instalar ID7 v2, reinstalando la misma versión .335, ejecuté la actualización como dice en ID7 Recovery v2, última actualización y en ningún momento me conecté a la conexión en serie, ¿cómo debo hacerlo? o es posible reinstalar una versión anterior?

Yes, something must have happened with my translator since my English is not good, I have version 70.00.335 in my mazda cx-5 2016, try to install ID7v2 by reinstalling the same version 355 as it says in ID7 Recovery v2 , but at no time could I make the serial connection, I was physically connected but in putty no text appeared to me, in the USB-TTL if only the red RX led lights up, is it the only thing it does, how should I do it? or can an older version be installed?

It seems that your cables have no connection to the CMU. Try to remove more insulation, so that your bare wire gets longer and put them in the 2S/2T slots farther than you think they have to be. And do not forget to connect the 3rd wire to Ground. This site about serial access basic knowledge you most probably know already? Serial Connection and for special ID7v2 for .335 and .352: ID7 Recovery v2

An older version could be installed, but if you choose e.g. 59.00.545 you still would need to do the serial access ID7v2, as you downgraded from .335. I think I read, that you could downgrade to 59.00.502 and then use the old serial access from www.mazdatweaks.com - but still it`s a serial access (with cables connected necessary) and there is no way around, if you want to install tweaks via USB.

If you will not success with your cables, there are two more options:
  • Opening the CMU and soldering the cables to the platine - photos of that are somewhere here in the forum
  • Buying proper Pins and crimp them to cables and insert them in the connector - see this post and the following ones for more details

Apparently if I am doing it as you mention it, will there be any way to know if the USB-TTL adapter works? otherwise I will try another and stripping the cable more. Thank you.

I do not know, perhaps someone else knows that. My USB-TTL Adapter has no LEDs at all. It might be that it is broken and you need a new one... but first I would try stripping the cables some more.

A fast way to check the adapter is to connect the transmit and receive wires together. That way any key-presses will be echoed back to the screen. If nothing echos back you have an issue with the software/drivers or adapter.
