Back in August 2017, HTC promised that Android 8.0 Oreo would come to the U11, U Ultra, and 10. The U11 (and U11 life) have both received their Oreo updates, and the 10 is the next in line. The Android 8.0 Oreo OTA is now rolling out to this 2016 flagship, and if you’re on the impatient side, you can download the RUU instead.
As it is with every 8.0 Oreo update, you can be sure to see picture-in-picture support, Autofill, notification dots, Instant Apps, and so on. This update carries the software version 3.16.617.2, and it should be starting to go out all around right at this moment. If your phone isn’t displaying the update and you’re tired of jamming the ‘Check now’ button desperately, you can also download the 1.8GB RUU (clicking the link will start the download). It is pertinent that you keep in mind that this will wipe your phone, so make sure that everything is backed up.
On another note, the U11 is now receiving its December security patch with version 2.42.617.1. The 1.9GB RUU for that can be found here (again, clicking will start the download).
HTC has pulled the HTC 10’s Oreo RUU download and the update page for unknown reasons, and it doesn’t seem like any HTC 10 owners actually received the update over-the-air. Apparently, the update caused a lot of confusion on the forums, as the only individuals who were able to even install the RUU were those who had paid for Sunshine S-OFF, extracted the firmware from the RUU, and flashed the firmware itself.
However, we could guess that not many HTC 10 users went through that whole process, especially with the update expected to come OTA.
Hopefully we will hear from HTC about what caused them to pull the Android 8.0 update for the unlocked HTC 10, and when another attempt might be made.
