Hello Guys,

I need your help to update the firmware. Im now on version-main: 1.15.401.4 and want to update to the newest (dont know which one...)

I searched for hours, but just find broken links and outdated tutorials.

Also I got a question:
Can someone tell me why it is possible with my old firmware to run Android 11?
I dont understand the connection between the firmware and the android version...


Model: HTC U12 Plus (HTC__034)

Android 11 (ViperExperience Beta 7)

Version-main: 1.15.401.4

Status: rooted

What I need to do?

Thank you for your help
