From what i have read since now, u had only bad flash ic or bad solder under flash ic. But now situation is differit now u have two problems:
1.flash ic
2.COBBA
Let me tell u why; first after u changed flash ic and flashing was succesfully but CS, u SHOULDN`T do anything to cobba, successfull flashing don`t mean that flash ic is ok.
Try to solder a new cobba because new ic`s come with ready made pin`s
Try same thing with flash ic, after this opperation reflash phone and should work, NO MATTER WHAT VERSSION u put inside,
I wish u luck, because u`ll needit,
