Well, we love you if you love Xposed, and we know how much hate thing sin your life when something as cool Xposed gets to not working anymore, and sends your device into a bootloop. Same with us. Well, if you own a Sony Xperia Z3 or Z4 or Z5 or any branch models of these three, normal Xposed installation can set your device into bootloop.
Luckily, there’s fix available for that. And it’s just been unearthed, and confirmed to be working too. All you need is to flash the unofficial Xposed file provided below, and then give your device a reboot.
Now, understand this that your Sony Xperia Z3 or Z4 will still bootloop. But only two times, and then it will reboot normally — so, uh, bootlooped fixed, right? Yep. Be patient with first two bootloops as third try will reboot normally.
Once you have flashed the above unofficial Xposed build using CWM/TWRP recovery, then you can go ahead and download the Xposed installer APK from official thread here by rovo89, install it, and download and install your favorite Xposed modules. Good luck!
