ExtBUSC: DEAD DEAD DEAD DEAD DEAD DEAD DEAD DEAD
means, you or some one else did "reset data1" to this phone by using mxkey.
it's kind of signature from us
to revive:
- full erase by 'get addr', select all, don't tick 'safe erase' do 'erase'.
- flash the phone fully.
- rebuild imei, write pm, unlock.
