Hi there, recently i bought used m8 and its android version is 4.4.3, it is made in ireland as htc said. It is s-off and has supercid 11111, It means previous owner customized this device. I need to know its orignal Cid and Mid so i will update it to marshmallow( since i am not receving ota updates), so please help me out what should i do...I also dont know it has stock rom/ recovery. Bootloader is locked. I guess it has stock recovery. I want any stock upgrade because this rom has many bugs like delaying messeges e.t.c. Thanks in advance
