Hello.There are problems with operation SYNC 3 v 3.4 22251, namely the language is reset from the set one to English, and the Bluetooth connection is also lost. I’m trying to update via Syn3Updater with a downgrade, but the following error appears on the screen. INSTL_ERR12. This machine originally had version 2.2, but I updated it to version 3.4.20237 and then to version 3.4.22251. I used the current version (3.4.22251) for a year and a half until the errors described above appeared. Tell me what could be the problem? Thanks

SYNC Region: EU

Navigation Variant: Nav

Manufacturer Year: Pre MY20

Install Type: OEM

Old SYNC Version: 2.2.16223

New SYNC Version: 3.4.22251

Do you have a error message, if so what is it?
INSTL_ERR12

Update Method: CyanLabs Manual Method

You need to get out of 3.4.22251 since it’s bugged.
Follow this guide → APIM Sync Settings Not Saving, VER_ERR08 Errors, Cannot Perform Master Reset or Upgrades/Updates (Solved)
