Hi, it's possible using paid services , e.g. "hcu-client" (4euros) . A8 Oreo is't supported, if you are running Oreo , you must downgrade to A7 Nougat via HiSuite.
If the roll back option is not available with your HiSuite ("switch to the older version", it may hapen), you must downgrade to the lower Oreo build version number doing the dload method (flashing Service ROM for your model and REGION (Cxxx)! This process will erase all your data!
Service ROM can be found here: https://androidhost.ru/search.html
. Type RNE- or Rhone- . Before you do anything, read carefully Software Upgrade Guidline in "ReleaseDoc" .
