Question Flashed HongKong Firmware by mistake, how to fix?

I was on the S5 v5.0 Port when i decided to go back to stock, started flashing the most recent firmware for our device ( i thought) N9005ZHUENF1 for the HK version im now hurtfully aware of )when i ran into the system/cache ext4 issue (no **** sherlock due to wrong firmware)

And i fixed this by downloadin the N3kitkat.torrent file and a valid pitfile and flashed that version which is AP_N9005XXUENA6_340325_REV03_user_low_ship_MULTI_C ERT.tar without issue.

Now to my issues
*no sound anywhere
*randomly vibrating like in haptic feedback
*slow and bad response and sometimes no response at all
*lockscreen wont open, i can draw my finger on the background as usual but then it goes black
*kies wont find my phone
*it reconnects to wifi spontaneiously
And more...

can i be on the hong kong bootloader still?
Have tried different firmwares and different kernels
Have tried to clean dirt from chargingport but no difference
What do you suggest i do?
