unable to do normal boot invalid kernel length

you need to flash whole stock fw, if you flashed this custom kernel using odin :)
15 days ago i got this error in my A7 :: unable to do normal boot invalid kernel length.

i tried almost everything i found on google or telegram groups but got no luck

Odin gives Complete write operation failed error

while in download mode device manager shows only :: samsung usb modem driver while other samsung device show in portable devices too

even tried to get Z3X but avaible v29.5 or something doesn't support newer samsung model


Do you know about any other tool than Odin or Heimdall that can help me in this situation

WLAN

Hi,
using V2.5 for a while now, but I am experiencing very poor WLAN-Performance.
I remember it working well in V2.0.

Is there something I can do ?
