Hi,
I’m hoping someone can point me in the right direction.
My son has bought a 2018 fiesta but it has had a warranty sync unit fitted by the Ford dealer.
I can confirm with the syn3updater that it is definitely a MY20 unit.
It is on sync 3.0 but I would like to change it to the latest 3.4 build.
I know it’s not supported on here but I would like to know if anyone has indeed successfully done this.
From what I have read it can be done by:
Jailbreaking the Apim via the Fmods jailbreak tool.
Format the APIM using Fmods reformat tool.
Reformat and install the latest sync 3.4 using the cyanlabs updater tool.
If anybody has any information on how it’s done or even better a step by step guide I would be more than grateful.
Thank you for the quick replies.
What is it that actually brick’s the units? I’ve read its a driver issue with the screen but also read its a formatting issue?
I think I would be happier knowing the exact reason that causes it to brick the unit.
Does the fmods universal reformat tool have the correct drivers then?
I’m a little confused why using the fmods reformatter and jailbreak gets around the driver issue?
Yes as it’s via jailbreak they are not restricted to only being able to use ford signed packages and therefore can modify the package adding additional drivers, newer boot images etc.
