this is my first tutorial, so I hope you enjoy it.
Flex 3 had an issue which is crashing in H3lix jailbreak, but I managed how to fix it and make it work in H3lix.
1-uninstall the flex you have first, then make sure you install it from the official repo, http:getdelta.co/
2-you must have filza, you can get the latest version from the offical repo if you want, http://tigisoftware.com/cydia/
3-open filza and go to /var/mobile/Library/Flex3/Flex.app and copy all files.
4-go to /Applications/Flex.app then paste and replace them.
5-respring or open H3lix and run uicache.
6-That's it flex should work now ,make sure you do that every time Flex get an update.
this fix only for H3lix jailbreak for 32bit, tested on "iPad4 10.3.3 H3lix".
if it's not working you can try the older version beta8, this version will probably work, so try install the new version on it, and then start from method 3, (it worked also for me) please run uicache, respring or reboot to fix some processing issues.
