The link to the instructions are in a text file within the compressed MiB aio file but here is a link to the instructions:

Ken:
These are the instructions that I used but they are wrong or maybe I should say incomplete. It is worded as if you do not have to turn on the ignition.

I agree. That part of the instructions could be clearer. The video is more clear:

@CaymanMatt @Treemagnet There are so many threads already on this process and even instructions posted it hardly seem like a worthwhile endeavor to start another one, besides how would you ensure that interested parties go to that one instead of any other thread. most forums have a policy of leaving up all material so any search will always bring up multiple hits.

I personally have been active not only here and on Rennlist as well for years and it has been my experience that many people refuse to start at the beginning and actually read the thread, they want somebody to start from scratch answering the same questions that have been covered off multiple times... add to this, even when the correct instructions are provided so many people skip steps, don't read them completely or simply wing it based on some notion that they know a better way... the incorrect assumptions are amazing!

Personally I don't have the time or permissions to manage such a thread, it would take a lot to keep it clean and uncluttered, you would be better off to have a DIY document on the forum. And the thing is this already exists, @Ken G just posted another link to one.

I'm all good with everything you say. Thank you! I certainly broke some rules during my installs. The AIO just sloughed it off and got the job done when I let it.

I'll say my knowledge of AIO is limited to this forum, and I've surely missed many posts. On that limited basis, and my three cars, I formed my doubt about the warning. I'm really sorry I've missed reading about them. People should know if there's an appreciable risk.

But you were maybe involved in such a case I take it? Any links? I'm keen to understand and correct my thinking. If it's just too risky to do this stuff without a charger, then I'll stop pushing my luck and get with the program!

Just about every credible set of instructions I have seen for the AIO process recommend having a suitable charger hooked to the car to the upgrade, I don't understand the pushback to doing this when most people already have a CTEK or equivalent... The need for this wasn't included on a whim.

As for issues, problems, mistakes, impatience, errors or simply deciding not to follow the instructions, what can I say, some just don't read or maybe they think they know a better way? This is a firmware update, interrupt it, or loose power and the results can leave your PCM in a state where some functionality is lost or worse the PCM doesn't work at all, why risk it?

So regarding failures and their causes, there have been a number posted in this thread alone, some people don't mind sharing there experience and asking for help, some go the route of a private message and you would not see them at all, I don't take information from a PM and share it, I have helped at least a dozen people this way, others by email, text, WhatsApp and even on the phone.

Over on Rennlist are more threads, duplicates too of course because people don't start at the beginning and read the posts, one is 80 pages long, lots of information, and yes questions repeatedly asked, but there you can find reports of problems and resolutions, I think that it is worth a read.

The problem is is that there are so many threads on the subject and they all point different places and have different information. But as I noted to Ken G, the instructions that I used which came directly off of the MIB site were not accurate in a way that caused me to basically have a failure. You can trust me when I say that I spent so much time trying to make sure that I got the information from the right place, got current information, etc before I actually ran the script. I still had a failure because the information I had - although mostly accurate - was inaccurate in a way that is causing me grief.

This is why I suggested a thread like the x431 programming thread that puts all the proper information in one place.

Believe me, I understand and appreciate all the effort that everyone has put into this. I'm just hoping to maybe prevent what happened to me from happening to others, as well as making it just easier for people to find the correct information.

MOO & FWIW

@OttawaSteve - If an updated instruction post was created for this thread, is there a way to make it sticky, at the top of every page of the thread, so it is easy to find when new people look here?

I can sticky the thread, but as far as I can see, the only way to make something appear on each page of the thread is to put it in the thread title.

OK. Thanks for looking.

Where is a failure that was caused by the AIO? You were pretty forceful in castigating me, as if I had ignored the known risks. I accepted your words as authoritative. But now, you just give links to long threads about MIB.

I'll grant that my experience installing MIB AIO of three cars is not definitive proof of anything, but it does provide some hard data points. Where are yours?

I don't want to give out bad advice, but nor should I have to defend my experiences against innuendo. Let's just seek truth about how things really work.

My point above is that people hesitate to do the AIO because of fears that have been overblown, and that if they had a clearer sense of the risks (probability and impact), more would go forth confidently and successfully.

Wow! This is heading off into the weeds (castigating, inuendo?), I see no where that I was anything but trying to be helpful, at no time did I reprimand you for your actions regarding AIO either. Additionally, I don't know what truth you are trying to find or determine here, AIO has been out for years, those that are just getting to this now are behind the end of the cycle (2023).

Why would you be asking or expecting me to provide you with empirical data on failures caused when using a free program supplied by a third party with no implied support? I am not the author of MIB or AIO but was involved with rollout testing of the various versions and helped vet the instructions that were initially released, and I have been involved or assisted in trouble shooting dozens of upgrades using AIO all over the world since it was first released, and before that with a manual version using MIB that needed to patched to each specific version of firmware on the PCM being upgraded.

When AIO was rolled out and the instructions were followed the results were very solid, but so many simply went their own way, making assumptions and ignoring what was suggested in those instructions, surely that is on that individual and no one else. If as an end user you wish to interpret or modify the instructions and processes that is completely up to you, but you do it at your own risk, and I don't think that the risks have been overblown and anyone attempting this update should be aware that real issues can happen, it would be improper to say it is fool-proof especially when not following instructions. The risk is certainly not zero, have you priced a replacement PCM?

 

[718socal]

Wow this went downhill fast. We, me, Westcoaster, MIB and others have spent a lot of time helping others on our own free time to offer AIO for free. We gave you advice on what not to do. It is your car and you can do whatever you want. You should show some respect for people like Westcoaster who will help anybody who needs help

 

[ReidMcT]

You should show some respect for people like Westcoaster who will help anybody who needs help

I do, and I did. Did that not come through earlier? I wrote very sincerely.

But respect goes both ways, doesn't it?

Here is @Westcoaster 's opening in replying to a reply I had made to another member:

"Thanks for sharing your opinion, but to be clear there have been problems and what you refer to as "bricked PCM's" that have happened in the course of doing the AIO update. I get the feeling that because you personally haven't experienced the problem or been involved in trying to restore a compromised PCM that it hasn't happened, again untrue."

I didn't think my ideas were unreasonable, but I was hearing that I was missing key facts that invalidated my thinking. It seemed like a straightforward refutation, which I accepted in full voice, and asked for the facts. I haven't been involved in any post-AIO install PCM restorations because mine didn't break, and I don' know anyone whose has. You?

N.B. the bricked PCM phraseology is not mine; it is from the AIO documentation that I was discussing. It's the sort of language that may push some to overestimate not only the probability of the most negative possible outcome, but even its severity.

With an open mind, I think I will for the time being maintain my mild advice:
A 718 with a decent battery and lights/fans off, doesn't need a charger to do this work.


The last word on this thread should be someone else's. Peace.

 

[718socal]

You never stop do you. This is why I stop being active here. YOU are always right.I get weekly or bi-weekly PM from someone bricking their modules with PIWIS. And yes a few people did brick their PCM with AIO before. Good luck

It may be time for a bit of a recap of the current situation on this topic.

This thread deals primarily with two downloadable packages and the application thereof, AiO and Maps.

AiO (All in One) is a self-executing update package for PCM4.0 that has a number of functions. The most requested functions are activation of wired AndroidAuto, wired CarPlay, and factory Navigation. Secondary functions are things such as setting a flag to allow lifetime map updates, and onboard WiFi for Track apps. The complete AiO download is about 1.8GB in size. Please note - AiO is not compatible with the later PCM version (I will call it PCM4.1) that does not have an optical disc drive. PCM4.1 was phased in sometime around early 2024 production. If your PCM does not have a CD/DVD slot, this package will not work, and there is no newer package available at this time. The most recent AiO file is MHI2_US_POG11_K5186_1-MU1476-AIO.7z dated March of 2023.

Maps file is region-specific, and is used to update the NAV maps to a later version. The latest North American files that we have access to is for 2024-25. This is especially needed if you enable NAV via AiO on an older car, as the maps included in your PCM will date from sometime prior to the build date of your car. (The maps in my 2018 were from 2015-16.) You can also update factory activated maps after using AiO to set the lifetime update flag. The Maps packages are rather large—the 2024-25 North American maps are 12.5GB.

The current issue is that the person or group who originally built, obtained and/or maintained these packages has gone radio silent, and the primary web site for downloads is down (and looks like it may not return). Both AiO and Maps are region-specific (AiO had different versions for US, EU and others, while the maps are obviously not world-wide).

There are a few of us here who have saved these packages (most, or maybe only, for North America). But having the few of us with files constantly uploading them to people's personal cloud drives is not a sustainable model. I was able to find one possible mirror for AiO, but while it appears to be the same release by date as the one from the old web repository, it is definitely smaller in size and not as complete as the one that everyone has used in the past.

Short term - some of us who have the files needed are willing to share, but we aren't going to be able to upload them to individuals willy-nilly forever. And the Maps file is too large for us to upload to most personal cloud storage.

Long term - while I doubt we can expect any further development on this (especially for the later PCM4.1), it would be best if we could find a place to mirror these files, both the North American which are the most common, but also the other regions if we can identify people who have copies to share. So if anyone has any ideas on where we could store maybe 50-100 GB of files for free downloading, please let us know.

If you are still in possession of the files, I would appreciate them as well. I am also in the process of setting up a server pc so maybe I can host it in the future. I'm lucky my 24 model has a CD player haha.

Looks like mibsolution.one is gone again, this time the domain name has expired.

@marth - Before we go through the hoops of getting the files uploaded somewhere you can access them, please verify your car's software version. Select CAR -> Set -> Software Update -> Version Info. We need to verify the top line as shown here.

 

[marth]

Hello, thank you for the quick reply. Mine is as follows.

 

[CaymanMatt]

I just discovered I put this request in the wrong thread. I'll try again.

Has anyone here actually done a restore to their PCM? I'm trying to figure out which is the correct restore to go to. I'm going to attach a photo to see if it helps.

I'm a bit worried that the writing of the backup in AIO didn't actually work as it supposed to since the line "restore backup components to unit" does nothing. There is a backup file on my SD card but looking at it on my computer it doesn't seem to be too in-depth.

Hello, thank you for the quick reply. Mine is as follows. View attachment 92695

Good. I have the AiO updater for that one, as well as the 2024-25 North American map files for Nav. The updater is 1.82GB, the maps are 12.62GB.

@Ken G - do you have these files recently uploaded anywhere right now?

Perfect! I have a 64 GB SD card, so I can put both the AiO and the Maps for NA on it at the same time?
