Wait so, I updated my MMI 3G firmware to the latest one I have found in this link - okayNo, you dont have to downgrade from 2018. First make sure that you're on K0260 and you must know which Activator is used FSC or Script. If FSC activator is installed then I recommend to remove it with FSC removal script (extract it to sd card root, put ignition on, insert sd card to slot 1). Dont worry about images in script they are in 800x480 resolution so they will override your mmi screen resolution. After you removed FSC Activator insert sd card with 2019 maps turn on Map view and wait for message about blocked maps for 2 minutes approx. Then insert sd card with Audi_3gb_fix-K0260 script Activator and follow the instructions on mmi screen. After script is applied reboot mmi and you are good to go. If you want to use second 2019 map you have to install 2017 map first (east or West) and then install 2019 you want. When reversing back to primary 2019 map the procedure is always the same 2019>2017>2019
Here is link for 2017 east map
I took maps which I have found there from 2019 - okay
Navi now says it's blocked - okay
And you are saying now if I take activator you provided I just wait till it tells me that navi is blocked, insert SD card into slot 2 it will tell me that some script will be applied I will follow instructions, it will just do something weird with the screen, then just reboot MMI and should be okay right?
