Before you modify your OP–XY
This is experimental, unofficial software for modifying your device's firmware.
Modified firmware can cause data loss, permanent hardware damage, or make your device unusable ("bricking"). Recovery is not guaranteed.
This site and its software are independent of teenage engineering and are not affiliated with, endorsed, sponsored, or supported by teenage engineering.
The software is provided as is, without warranty. Proceed only if you understand and accept these risks. Back up any device content you want to keep before installing modified firmware.

Choose OS
Is your OP–XY on OS 1.2.1?
This builder works only from teenage engineering’s OS 1.2.1. A Hadden OS made from an older OS does not count: if your OP–XY shows HADDEN at startup, it must end in 1.2.1.
Install OS 1.2.1 first.
Install it with teenage engineering’s updater, as for any OS update. It keeps your projects and replaces a Hadden OS.
