We should have anticipated it — OnePlus and missed software update deadlines kind of go hand-in-hand these days — but the One’s long-awaited CyanogenMod 12 firmware based on Android 5.0 Lollipop has been delayed. Again.

OnePlus originally promised the release within 90 days of Lollipop’s public debut, which came way back in November. Ever since then, the Chinese startup has been making new promises that are subsequently broken.

Back in mid-March, OnePlus promised CM 12 would be available before the end of last month — alongside its new OxygenOS software, which is also based on Lollipop. But neither have arrived yet, and there’s no word on when they’ll be available.

“Unfortunately, CM12 won’t be OTAing today due to certification issues as well,” reads an update on the OnePlus forum. “All parties are working together to resolve the problems as soon as possible.”

OnePlus adds that it understands customers are frustrated, and it vows to be “more careful with our ETAs in the future.”

If you’re a One owner who’s fed up with waiting, you can flash the CyanogenMod 12 nightlies manually to get your hands on Lollipop. They don’t contain all of the features you get with dedicated One firmware, but most things are there, and they are a great alternative in the meantime.
