Downloaded the Gapps for the above rom---whether Full, Mini or Basic- and they all end up in error in the TWRP flash sequence--Open Gapps open_gapps-arm-6.0-full-20160623 .zip. If I just flash the updated rom to S3 without Gapps, the phone still updates the rom, and everything else is as is. I forgot to wipe cache and Dalvik cache- phone still works, but I take it that a lot of previous junk from earlier rom has been left behind. Is this what they call a dirty flash ?? I can't seem to find Gapps for this rom apart from the one entered above. Any ideas please ?? Thanks. PS Got another S3 and S4 to update.
