2) If problems are detected after the "dirty" firmware, you should follow the simple recommendations given below:
• Uninstall the Google Keyboard application (GBoard), if one was installed earlier
• Clear data for the Play Market application and roll it back to the original version
• Uninstall Titanium Backup application with tails
• in TWRP wipe Dalvik and Cache
• After that install the patch again
