Chinese ZTE blade A601 , unable to install gapps

Hello,
Recently I've bought in china ZTE BA601 for chinese market. And I can't install any google services on it. I tried to install opengapps and cgapps from custom recovery(TWRP doesn't support this device) and always get message "updates failed because of the wrong version" , though I tried versions for ARM android 5.1, which should be fine. I also tried to install google play services apk, and it crashes immediately - "google play services has stopped...", so I can't install anything related to google - inbox, translate,maps etc.
Any advise for a newbie?
