Downgrade to Upgrade Issuse

OK, that’s progress. So you are still at Sync 3.3 but the screen is correct now?

VER_ERR08 – Error is VER_SETTING_VER_INFO_ERROR. I am doing some research on this to see what specifically could be the issue. The error means that your APIM cannot save the file for the setting.

I wonder if this is a cached error. You could hold the Radio Power button and Next Track, until screen goes black. Do that 2 times in a row, then try the update again. This reboots the unit and will clear the caches.

The last file you posted indicated Sync 3.3 with the Sync 3.4 voice file. This can cause performance issues, but I don’t know if it might do this.
4U5T-14G381-AN
5U5T-14G391-CS, should be 4U5T-14G391-CJ.

The storage has an issue:
<d2p1:PartitionHealth type=“/fs/Nuance/” total=“465M” available=“3.2M”/>
<d2p1:PartitionHealth type=“/fs/rwdata/” total=“1.2G” available=“0”/>
<d2p1:PartitionHealth type=“/fs/mp/” total=“496K” available=“17K”/>
<d2p1:PartitionHealth type=“/fs/mp/” total=“1.4G” available=“505M”/>
<d2p1:PartitionHealth type=“/fs/images/” total=“25G” available=“24G”/>

This is the culprit, this partition needs to be fixed/emptied. There is no space to save data for the updates, etc. If the unit was not MY20, a reformat would do it. But that is not an option here.

This partition contains “fordlogs” and “slogs”, which are supposed to be temporary, but have run the partition full. Deleting these would free up space in the partition which should fix the VER008 issue.
