If i ignore the above and go ahead and flash the patched image trough odin i get this after the phone boots

Now i reseted the phone , restart funny i still have magisk 17.1 installed but my problem now is that my imei is gone and so my network connection so i'm not able to get any signal from any mobile network (ee,o2,vodafone etc)

If i try to install a module from magisk i get the fallowing error: Unable to extract zip file. Installation failed!

Root on the other hand is working.

If i reflash the stock all comes back to normal

Can anyone give me hand with this.

Many Thanks,

George
