[HTC U11 Life Guides, News, & Discussion] saturday_night:
These Files and Guides are NOT for the US Sense Version, use only for the U11 life Android One Version!!!​

General information

These Files can restore your Device back to Stock or root your Device. The U11 life Android One Version has a/b partitions, so before flashing something you need to know which parition is active

Reboot your Device into Bootloader

Connect it to your PC and make sure you have a working Fastboot connection with

fastboot devices

Enter the command

fastboot getvar all

Search in the result for these lines

(bootloader) has-slot:system:yes
(bootloader) current-slot:a

That means slot a is active and you need to flash your Files to boot_a and system_a

If slot b is active you need to flash your Files to boot_b and system_b

You can change the active partition using one of these Commands in Bootloader

fastboot set_active other
fastboot set_active a
fastboot set_active b

If that doesnt work for you, you should update your adb&fastboot installation.
