Verify Software Compatibility Prior to Flashing

[dagger969]

Are there any tools to help verify that an update is compatible before I push it? There are so many posts about breaking modules, missing calibration files, etc. It would help everyone if there are some tips on how to research these things for ourselves.

Are there any modules that I should be more careful with? If they all continue to communicate when an update fails, then it isn't a big deal. A lot of people on here have access to IDS. I do not. Thats not an option for me if I break something.

I updated the BCM on my car and it stopped functioning. I was able to fix it by going back to the old files. I could still communicate with the BCM, so it wasn't a big deal.

I think that people sees tat there a update .wich have higher letter than their in the car just jump 3-4 letters up in one programing I think that if we took it one at a time there will be lees problems there are a drop down menu where it is possible to select wich file to update . No one know what they have altering in the updates .It could be that there are some thing changed in some of the files if we go from ex. ******-*d to *****'-*j that is nessesary for the next update to Work
the problem wil come if there some thing changed in some of the file in between
Iam one of the Lucky ones that have ids and etis ids and fdrs access and original vcm 1-2 and access to a vcmm
and have rescued a few modules that have been out of reach with ucds and other tools but with fdrs i could reprogram them to be seen Again

So it's very dangerous to update modules by UCDS.

i dont think that it is dangereus to do so if you just dont take the large step 4-5 level at once but try to do it in more tempi then it should be more safe but there are possible some who knows tht could tell if i am on the rigth way

I agree. I just wanted to ask if there were any tips. People in this forum have done some very clever things. I don’t have the experience or knowledge to try them myself.

I recommend not to update every module u see, but to wait and verify if the update is correct

That is my question. I don’t know how to verify that an update is correct. I also don’t want to post on the forum every time I have a question.

I hope this isn’t a dumb question. Are there any modules that completely stop responding when incompatible firmware is sent to them? If I can always try to send again after a failure, then it isn’t a big deal. This is what happened with my BCM. Until I learn more, I’m avoiding things that seem critical like ABS.

Every module can stop responding
