X-Reallity Not WORKING!! topic

I was on iHackers 2.0 and xreality was working fine.then i updated it to 2.1 and x-reality wasnt working.I just thought that its a software problem from iHackers 2.1 .but today I just relocked my bootloader and flashed the 14.2.A.1.136 and still the xreality isnt functioning .
anyone has any solution?!
