How to flash Android 8.0 Oreo RUU Stock Firmware on HTC U11 using SD Card

Many of you know the fact that HTC U11 is the latest flagship phone from the Taiwanese smartphone manufacturer as long as you are already owners of this handset. Are you though aware of the fact that this device is currently receiving the latest Android 8.0 Oreo update too? Yes, I know that the OTA update usually takes time depending to tour current location and country, so my advice is to download and manually flash it on the smartphone.

After all, an XDA senior member, 5m4r7ph0n36uru, has released a generous collection of RUUs or ROM Update Utility files. Be sure of the fact that they really are the very same files that are released by HTC in different regions and even better, the collection of zip file includes all of the variants for the HTC U11 released in US, UK and Asian countries including India.

Don’t do that if you are a newbie, yet I am sure that an advanced Android user has no fear of such a procedure. And do not even think of starting the operation before getting ready. You have to:

  • Make sure that you are using a compatible SD card before even thinking of the installation operation;
  • Verify that you have more than 70% battery left on your smartphone. This is a new device, I know it, yet a small thing like this one could lead to bricking it for good.
  • I know that a smooth installation of the latest firmware on your HTC smartphone is all that you want, but understand that you are the only one to be blamed if something goes wrong.
