[Need Help] Samsung Galaxy A5 2016 Soft brick

Dear Readers,

I recently bought my Samsung Galaxy A5 2016 and its an excellent phone, although, I rooted it quite soon after purchase.

Used CF-Autoroot and everything worked just fine,
Now today I wanted to get Xposed up and running on my phone, and I wanted to back up everything first.
I installed Flashify and downloaded a TWRP img, I flashed it and rebooted my phone.
Heres some info now:
Normal boot: Kernel is not seandroid enforcing
What comes next: Bootloaded exception
[RST_STAT = 0x10000]
ASV TBL VER = 32768
LOT_ID = N469X
-Some useless CPU heat info etc-

Exception: do_handler_sync: UNKNOWN

pc : 0x40205000 l r : 0x43e07c68 sp:"0x43f07f40


Now after that I shut down with vol down+main menu+power button
And I boot again with vol up+main menu+power button

First comes up:
Installing system update...

Then:
On the bottom of the screen: dm-verity verification failed. . .
And ofcourse in the middle the basic options
On the top
Android System Recovery <e3>


PLEASE help me out cause I really dont know what to do now..
Greetings from The Netherlands

Edit: I get different text on the first normal boot every time it seems, some weird letters and numbers etc.
Example: B f $ AFA G $ AFB p G @F H1 G pl
