I am currently on MI7 and in download mode it's a TGY (Hong Kong) CSC. Ideally I'd like Australian or UK CSC and MI7 or less ROM.
Then I can try the root method and if I have a problem I am not reduced to using a ROM that will prevent me from trying again unless I want to break Knox.
As a side issue, when going into DL mode, I get the android bot, then a smaller one, on its back with a red exclamation above the open chest. Is that a usual picture or is it indicating something wrong?
