I've just installed Lineage os on my zte axon 7, but I'm having trouble flashing gapps. I've tried the stock, full, and mini sizes and they all don't work. Every time I try flashing them, it says that it couldn't find the md5 file or something like that. It also says that my phone architecture is arm64, but every time I download one of the arm64 versions , it doesn't show up in the install section of twrp. I'm using a sd card btw. Does anybody have lineage os with gapps that can help me?
