Hi,
After downgrade i followed every step from tutorial but when i arrived to the step where i need to update back to my old latest version, i can't find version 2510 so i upgraded to 2506 but from then aprox january, i do not receive any update. I'm from romania and the car was set by default on NL and now is on NL. Now I think to make an manual update to 2511 to see if it trigger an OTA update.
The car say that I have latest version which for me is 2.1.0
don't forget to change country code to Singapore before upgrading
