2023-11-07 System & MCU update for S4 Pro/Ultimate 1920x720

Posted by Daniel Kim on


As this update includes XML update, before you update anything, please take a picture of all configuration under the factory settings options including AUO, Hstart option. Once XML gets updated all the known configuration will be lost and you need to configure them into previous configuration manually. There will be a lot of errors due to car mode mismatch resulting scrambled screen in OEM mode, loss of MMI control etc. Once XML is updated, reset the system by poking the reset hole with a paper clip. You should feel a click.  Then the system will boot into Android giving you few minutes to correct factory settings to the previous configurations. 

- Fixed the annoying music playing and immediate stop issue at carplay/android auto

This is for 1920x720 S4 Pro/Ultimate only. Different versions will be available on the further notice.
