A method that works for me on iOS. Geo phone USA, geo VPN USA not New York, New York gives a shadow on the account, and it is me.
1. Phone without a sim card.
2. Register an account on geo usa, it does not matter on the phone number or mail.
3. Go to the account, you can immediately formalize it.
4. Close TikTok, do not log out of the account.
5. Change the geo of the phone to the desired one, for example, Germany
6. Change your VPN geo to Germany.
7. Go to TikTok and start uploading videos.
If this does not work, then take the old US account on which were uploaded videos, start with the first paragraph, and delete old videos, if they are not needed.do all the same, just already with a ready account. I will be glad if someone will check it and give feedback.
