Hello peeps. I would like to thank Cyanlabs for their excellent software and continued support. I upgraded to 3.4.26057 but have since read that this is a dealer only version. I have not experienced any problems with tihs version, however I would like to roll back to 3.4.23188 since this is an official release. I have used Syn3 2.14.2.0 and updated the current version installed to 3.4.26057 and input the new version I want to roll back to, 3.4.23188 and keep existing maps, but the Syn3 software downloads 3.4.26057 files. This was confirmed when I completed the install and noticed the version number had not changed. I also noticed that the Syn3 software shows the APPS package version as 3.4.26057 when selecting 3.4.23188. Can someone help? * * * **SYNC Region:** EU **Navigation Variant:** Nav **Manufacturer Year:** Pre MY20 **Install Type:** OEM **Old SYNC Version:** 3.4.26057 **New SYNC Version:** 3.4.23188 **Do you have a error message, if so what is it?** No **Update Method:** CyanLabs Syn3 Updater **Syn3 Updater Version:** 2.14.2.0 **Syn3 Updater Documentation Read:** yes **Syn3 Updater Log File** ```no-highlight CYANLABS - SYN3 UPDATER - V2.14.2.0 Branch: Stable Operating System: Microsoft Windows 10 Home (2009) PREVIOUS CONFIGURATION Version: 3.4.26057 Region: EU Navigation: True Install Mode: Auto-Detect (autoinstall) Install Mode Overridden: False My20 Protection Enabled: Auto-Detect DESTINATION DETAILS Mode: Drive Model: SanDisk SanDisk 3.2 Gen1 USB Device Size: 233.1GB FileSystem: exFAT Partition Type: MBR AUTOINSTALL.LST ; CyanLabs Syn3Updater 2.14.2.0 Stable - Autoinstall Mode - Sync 3.4.23188 EU [SYNCGen3.0_ALL_PRODUCT] Item1 = RWDataCleaner TOOL - PU5T-14G386-BB_1690840002000.TAR.GZ Open1= SyncMyRide\PU5T-14G386-BB_1690840002000.TAR.GZ Item2 = VOICE - 5U5T-14G391-AT_1660763323000.TAR.GZ Open2 = SyncMyRide\5U5T-14G391-AT_1660763323000.TAR.GZ Item3 = GRACENOTES - 4U5T-14G423-AC_1615425645000.TAR.GZ Open3 = SyncMyRide\4U5T-14G423-AC_1615425645000.TAR.GZ Item4 = ENH_DAB - 1U5T-14G658-AH_1644006443000.TAR.GZ Open4 = SyncMyRide\1U5T-14G658-AH_1644006443000.TAR.GZ Item5 = APPS - NU5T-14G381-AE_1778770590000.TAR.GZ Open5 = SyncMyRide\NU5T-14G381-AE_1778770590000.TAR.GZ Options = AutoInstall FILES (5) PU5T-14G386-BB_1690840002000.TAR.GZ (3.2KB) 5U5T-14G391-AT_1660763323000.TAR.GZ (1.5GB) 4U5T-14G423-AC_1615425645000.TAR.GZ (689MB) 1U5T-14G658-AH_1644006443000.TAR.GZ (57.5MB) NU5T-14G381-AE_1778770590000.TAR.GZ (869.9MB) LOG [07/09/2026 14:34:37] Selected Region: EU - Release: Sync 3.4.23188 - Map Version: Keep Existing Maps [07/09/2026 14:34:37] Install Mode: Auto-Detect (autoinstall) Forced: False [07/09/2026 14:34:37] MY20 Protection: Auto-Detect [07/09/2026 14:34:37] Formatting USB drive [07/09/2026 14:34:37] Re-creating partition table as MBR and formatting as ExFat on selected USB drive [07/09/2026 14:35:18] Checking Existing File: PU5T-14G386-BB_1690840002000.TAR.GZ [07/09/2026 14:35:18] Validated: PU5T-14G386-BB_1690840002000.TAR.GZ (Skipping Download) [07/09/2026 14:35:18] Checking Existing File: 5U5T-14G391-AT_1660763323000.TAR.GZ [07/09/2026 14:35:37] Validated: 5U5T-14G391-AT_1660763323000.TAR.GZ (Skipping Download) [07/09/2026 14:35:37] Checking Existing File: 4U5T-14G423-AC_1615425645000.TAR.GZ [07/09/2026 14:35:44] Validated: 4U5T-14G423-AC_1615425645000.TAR.GZ (Skipping Download) [07/09/2026 14:35:44] Checking Existing File: 1U5T-14G658-AH_1644006443000.TAR.GZ [07/09/2026 14:35:45] Validated: 1U5T-14G658-AH_1644006443000.TAR.GZ (Skipping Download) [07/09/2026 14:35:45] Checking Existing File: NU5T-14G381-AE_1778770590000.TAR.GZ [07/09/2026 14:35:51] Validated: NU5T-14G381-AE_1778770590000.TAR.GZ (Skipping Download) [07/09/2026 14:35:51] Preparing USB drive [07/09/2026 14:35:53] Checking Existing File: PU5T-14G386-BB_1690840002000.TAR.GZ [07/09/2026 14:35:53] Copying: PU5T-14G386-BB_1690840002000.TAR.GZ [07/09/2026 14:35:53] Validating: PU5T-14G386-BB_1690840002000.TAR.GZ [07/09/2026 14:35:53] Copied: PU5T-14G386-BB_1690840002000.TAR.GZ [07/09/2026 14:35:53] Checking Existing File: 5U5T-14G391-AT_1660763323000.TAR.GZ [07/09/2026 14:35:53] Copying: 5U5T-14G391-AT_1660763323000.TAR.GZ [07/09/2026 14:36:21] Validating: 5U5T-14G391-AT_1660763323000.TAR.GZ [07/09/2026 14:36:49] Copied: 5U5T-14G391-AT_1660763323000.TAR.GZ [07/09/2026 14:36:49] Checking Existing File: 4U5T-14G423-AC_1615425645000.TAR.GZ [07/09/2026 14:36:49] Copying: 4U5T-14G423-AC_1615425645000.TAR.GZ [07/09/2026 14:37:01] Validating: 4U5T-14G423-AC_1615425645000.TAR.GZ [07/09/2026 14:37:03] Copied: 4U5T-14G423-AC_1615425645000.TAR.GZ [07/09/2026 14:37:03] Checking Existing File: 1U5T-14G658-AH_1644006443000.TAR.GZ [07/09/2026 14:37:03] Copying: 1U5T-14G658-AH_1644006443000.TAR.GZ [07/09/2026 14:37:04] Validating: 1U5T-14G658-AH_1644006443000.TAR.GZ [07/09/2026 14:37:05] Copied: 1U5T-14G658-AH_1644006443000.TAR.GZ [07/09/2026 14:37:05] Checking Existing File: NU5T-14G381-AE_1778770590000.TAR.GZ [07/09/2026 14:37:05] Copying: NU5T-14G381-AE_1778770590000.TAR.GZ [07/09/2026 14:37:18] Validating: NU5T-14G381-AE_1778770590000.TAR.GZ [07/09/2026 14:37:21] Copied: NU5T-14G381-AE_1778770590000.TAR.GZ [07/09/2026 14:37:21] Generating Autoinstall.lst [07/09/2026 14:37:22] ALL FILES DOWNLOADED AND COPIED TO THE USB DRIVE SUCCESSFULLY! ``` ---

Thanks. Also noticed the full version list under car configuration does not list version 3.4.23188. ---

Yep, that’s known and not that relevant, as users can manually input any version. ---

I would like to understand why it is quoted as below posts. Shall I leave as 3.4.26057 or downgrade to 3.4.23188? > [@Want to update from 3.0.18025 to 3.4.26057](https://community.cyanlabs.net/t/want-to-update-from-3-0-18025-to-3-4-26057/27657/3): > > I would also not go any higher than 3.4.23188 on a NAV APIM or 3.4.21265 on a non-NAV APIM. Ford currently has 3.4.26057 as a dealer only install to deal with a specific recall issue. > [@SYNC 3 update 3.4.26057](https://community.cyanlabs.net/t/sync-3-update-3-4-26057/27762/2): > > Drop your build to 3.4.23188, it doesn’t require reformat. 3.4.26057 isnt really a general release, right now Ford has it as a dealer only install. Also this has been quoted > [@SYNC 3.4.26057 unstable on 2017 Ford Focus – CarPlay crashing, lagging and freezing](https://community.cyanlabs.net/t/sync-3-4-26057-unstable-on-2017-ford-focus-carplay-crashing-lagging-and-freezing/27528/6): > > I’m aware, that you’re not on 23188. Ford never bothered to worry about 23188 on non-supported hardware (eg G/H/J APIMs) so why would they test 26057. Builds between 21265 & 23188 are affected by the RWData partition bug Personally I’d stay on 21265 since that release was clean across all Sync3/3.4 APIMS, you should be running your factory AB. So, for a MY18.5 Kuga what version do you suggest is the best/stable version to install? Sorry to be a pain but I think it may require clarification so that others can understand what version is best/stable for their vehicle. Many thanks for your patience. 🙃 ---

As I said above regarding non-Sync 3.4 native APIMs. “I would also not go any higher than 3.4.23188 on a NAV APIM or 3.4.21265 on a non-NAV APIM”. Basically if the car is older than 2019, follow the above. ---

I have 3 cars that are 2018 and 26057 has worked perfect in all of them. There is no problem going up to 26057. Many opinions but no real problems. ---

Since we are talking about this, I agree: if you do not see any issues, why would you downgrade?. All versions accesible through Syn3udater are official releases… ---

This should be fixed… I’m not sure why you would want to downgrade, but if you really want to, you should be able to do so now… ---
