Basically the phone has an unlocked bootloader and has TWRP 188.8.131.52 installed .
I have since installed the 5.1 official untouched EU rom using the ADB sideload method . ( TWRP would not read/detect my external SD ) .
Now I am back to my original problem , the radios on the phone don't work . I have tried flashing the radio firmware multiple times but this gives me the same error every time
assert failed: format ("raw" "EMMC", "modemst1", "0", "/modemst1")
E:Error executing updater binary in zip '/data/media/0/sideload.zip'
Updating partition detals...
Despite the error , I just restarted the phone and it works !
Now im getting a weird random 'boot into recovery mode ' on its own !
