@visakkus Hi, thanks for your support.
Normally, we offer two versions for XGIMI projectors: Chinese vesion for Chinese customers, and Global version for customers from overseas. But it's not for all models. H1S has the Chinese version only, please don't switch the system to avoid the possible compatibility issues, booting issues and system crash.
Please check with the original reseller or our Chinese service team for the system issue, appreciate your understanding: https://account.xgimi.com/pass/login?callback=%2F%2Fshop.xgimi.com%2FrepairApply.html
