Install flashfire and supersu from the google play store and perform the same steps.

Updated from 5.2.11.3A to 6.7.1.17 beta Chinese update
Folowed spanish guide
Got the supersu and flashfire from google playstore
Moved the chinese update to root directory using the phone folder manager app
The global update was in the download folder
Granted root
Installed supersu with Normal option
Granted root to flashfire
Selected in flashfire the global zip and checked the options ...
