"sounds like a more severe problem that you cant solve with a simple solution..
typically if a phone acts this was it can be a damaged qcn, damaged modem, damaged security, damaged efs partion... all of which to fix you would require either serious hacking skills or a cellphone box tool such as octopus box.... with these tools you can write these otherwise unaccessible partitions, but in some cases such as efs you would require an efs backup from another phone same model to repair or an existing efs backup.... bring it to a cell software tech or search gsm server forums... in any case you require root access , for g925w8 cf autoroot is boss...."
