I've flashed plenty of Z6tv's with cricket monster file.
Put phone in bootloader mode by turning it off or removing battery 1st.
Then Press and Hold # and * on the keypad next insert USB Cable, phone's screen will turn blue.
Use RSD Lite, Load the VRZ_Z6TV_01.16.0CP_PRImm82931_MONSTER_04 file into RSD Lite and press start. NOW AT 2% PULL THE CABLE FROM THE PHONE
Let RSD FAIL Close it, reopen it, Load the cricket monster file and flash. LET IT COMPLETE phone should now have the full cricket monster on it.
