While updating a new binary everything was wiped!

So, i have root for about 2 months. Everything went fine until i got a notification that the Su binary had to be updated. So i pressed the button ton update it the normal way. After that my phone went into a boot loop. I searched up hundreds of post to see how to get out of a boot loop. But nothing worked. But when i was in the boot loop i connected my phone to my PC and copied everything to it. Then i got some hope. After my phone started with the official firmware, my phone downloaded all the apps by itself. But it didn't put my contacts back. So after that i realized that i had a NANdroid back-up. I was happy again. But unfortunately after i restored it, my pone went back in a boot loop and got stuck.:crying:. After i installed the firmware AGAIN all my apps and basically how it was before everything changed, came back. I was happier than ever before. I went to bed with a nice feeling. Than i woke up and got the message again about updating the Su binary. So now i thought nothing would happen. And this time i updated it with TWRP. But again i failed and got stuck again. I installed the firmware again for the 3rd time. After it started, i looked if i still had a NANdroid backup. And i actually had. So i restored and my phone got stuck again. So i installed the firmware again, hoping it would put everything back like the previous time. But it didn't. I searched up how to get your contacts back. My contacts weren't in my Gmail account. The Android Data Recovery program did nothing but ****. I couldn't import my contacts. Because somehow there weren't any. My last hope was my whole back-up of my phone. It took approximately 5 hours to restore. But even that didn't put my contacts back. I lost my hope. But then i saw that i had backed up my contacts with Titanium Backup. And i restored them and restarted my phone. It only restored some contacts and Skype names i didn't care about. Then my hope was officially lost. I didn't know what to do. I rooted my phone for only one reason and that was to get IOS emojis. And i even got them. I never knew that this Su binary update would totally F*UCK up my phone. Well thanks for that. And if somebody still has a clue, let me know. Because my contacts were me number 1 priority.
