@Lobster I guess you are on an FP3, so the download link would be at https://ota.ecloud.global/api/v1/FP3/community/. Here is my report of how I switched an FP3 from T-official to A15-community: https://community.e.foundation/t/feedback-for-v3-1-1/73830/46?u=urs_lesse As I remember, data was taken over and not reset – I did not need to change the (locked) bootloader, so no factory reset was triggered.
