I upgraded my original 3.0 from my 2016 Focus RS to 3.4.20021 using the downgrade, then upgrade tool. Since then I’ve had a few bugs. Bluetooth disconnects repeatedly, Audio off when I start car until I change stations, USB port not compatible…
I’ve been trying to update to any of the newest builds to see if that helps. I constantly get the memerr_003 error. After reading the forum over and over I was thinking I ran out of storage space. I’ve even tried to install just the software, no apps or gracenotes. Still nothing.
I tried to use the APIM interrogator file and get a file_004 error on that one.
Any ideas on what I have to do to update to newest build?
Sometimes SYNC caches the error, reboot the unit, either disconnect power to the battery, or press and hold POWER + FWD for ~10 seconds or leave the car alone for ~30 minutes
Other than that assuming you are creating this file manually you likely have the wrong line endings, or you have special line ending characters or you aren’t saving it as plaint text and instead are opening it with wordpad, textedit, word etc. it must be plain text, use only notepad on windows or textedit on mac (in raw format)
